Answer: the cost of Parker's tuition is $17955
Step-by-step explanation:
Let x represent the cost of Parker's tuition.
Parker was able to pay 44% of his college tuition with his scholarship. This means that the amount that he was able to pay with his scholarship would be
44/100 × x = 0.44 × x = 0.44x
The amount that is remaining for him to pay would be
x - 0.44x = 0.56x
If he paid the remaining $10,054.52 with a student loan, it means that
0.56x = 10054.52
x = 10054.52/0.56
x = 17954.5
Rounding up to the nearest whole number, it becomes
x = $17955
A 1500 kg hippo is completely submerged, standing on the bottom of a lake. What is the approximate value of the upward normal force on the hippo?
Answer:
About 428 N
Step-by-step explanation:
Weight = 1,500 * 9.8 = 14,700 N
Density = Mass ÷ Volume
1,030 = 1,500 ÷ V
V = 1,500 ÷ 1,030 = 1.46 m^3.
Buoyant force = Density * g * V
Buoyant force = 1,000 * 9.8 * (1,500 ÷ 1,030)
Buoyant force = 9,800 * (1,500 ÷ 1,030) = 14,272 N.
Net force = 14,700 – [(9,800 * (1,500 ÷ 1,030)]
The upward normal force on a 1500 kg submerged hippo is approximately equal to its weight, calculated as its mass times the acceleration due to gravity (1500 kg × 9.81 m/s²), resulting in a force of 14715 N.
Explanation:The question is asking about the upward normal force on a submerged hippo in a lake. To find this force, we must understand that the upward normal force that the ground (or in this case, the lake bed) exerts on the hippo is equal to the weight of the hippo, which is the product of the hippo's mass (m) and the acceleration due to gravity (g).
In equation form: Normal Force = m × g. Plugging in the values, we have a 1500 kg hippo and the acceleration due to gravity is approximately 9.81 m/s². Therefore, the upward normal force is:
Normal Force = 1500 kg × 9.81 m/s² = 14715 N.
This is the approximate value of the upward normal force exerted on the hippo standing on the bottom of the lake.

Leah gets to paint her room since she bought a new bedspread set. Two gallons of paint covers 800 square feet. How many gallons of paint will Leah need to paint her entire room, which is 1,200 square feet?
Answer:
3 gallons
Step-by-step explanation:
If two gallons of paint covers 800 square feet, 'x' gallons of paints will cover 1200square feet room where x is the number of gallons needed to paint the 1200 square feet room.
Mathematically,
2 gallons = 800sq.ft
x gallons = 1,200sq.ft
x × 800 = 2 × 1200
x = 2 × 1200/800
x = 3 gallons
Therefore Leah will need 3gallons of paint for 1200sq.ft room
Two pools are being drained. To start, the first pool had 3700 liters of water and the second pool had 4228 liters of water. Water is being drained from the first pool at a rate of 31 liters per minute. Water is being drained from the second pool at a rate of 42 liters per minute.
This is a comparison problem involving rates. We multiply the rate of draining by the time and subtract the result from the initial amount, which gives us the amount of water after that time.
Explanation:This problem is considerate a comparison problem that involves rates of draining water from two pools. In these cases, it's crucial to keep the rates and the initial amounts separate to correctly solve the problem.
The first pool is initialy with 3700 liters of water and the draining rate is 31 liters per minute. The second pool from the start has 4228 liters and is being drained at a rate of 42 liters per minute.
To know the amount of water in each pool after any given time in minutes, we would multiply the rate by that time, and subtract the result from the initial amount of water.
For example, if we wanted to find out how much water was left after 10 minutes, we would do the following calculations:
For the first pool: 3700 - (31 * 10) = 3400 liters remained.For the second pool: 4228 - (42 * 10) = 3828 liters remained.Therefore, after 10 minutes, the first pool had 3700 liters and the second one had 3828 liters of water.

A private opinion poll is conducted for a politician to determine what proportion of the population favors adding more national parks. How large a sample is needed in order to be 98 % confident that the sample proportion will not differ from the true proportion by more than 6 %?
Answer:
n≅376
So sample size is 376.
Step-by-step explanation:
The formula we are going to use is:
[tex]n=pq(\frac{z_{\alpha/2}}{E})^{2}[/tex]
where:
n is the sample size
p is the probability of favor
q is the probability of not in favor
E is the Margin of error
z is the distribution
α=1-0.98=0.02
α/2=0.01
From cumulative standard Normal Distribution
[tex]z_{\alpha/2}=2.326[/tex]
p is taken 0.5 for least biased estimate, q=1-p=0.5

To prepare for a marathon, Henry gets a new pair of running shoes. If Henry runs 20 miles each day in week 1 and adds 12mi to his daily routine each week, what is the total mileage on Henry's shoes after 5 weeks?
Henry will have run a total of 1540 miles on his new running shoes after 5 weeks.
Explanation:To find the total mileage on Henry's shoes after 5 weeks, we need to calculate the distance he runs each week and add them up.
In week 1, Henry runs 20 miles per day, so the total distance he runs in week 1 is 20 miles * 7 days = 140 miles.
In week 2, he adds 12 miles to his daily routine, so he runs 20 miles + 12 miles = 32 miles per day. The total distance he runs in week 2 is 32 miles * 7 days = 224 miles.
We can continue this pattern for the remaining weeks:
Week 3: 44 miles per day, total distance = 44 miles * 7 days = 308 miles
Week 4: 56 miles per day, total distance = 56 miles * 7 days = 392 miles
Week 5: 68 miles per day, total distance = 68 miles * 7 days = 476 miles
The total mileage on Henry's shoes after 5 weeks is the sum of the total distances in each week: 140 + 224 + 308 + 392 + 476 = 1540 miles.

Use the graph that shows the solution to
f(x)=g(x) .
f(x)=−3/4x^2+3x+1
g(x)=2x
Graph A is the correct representation, as it aligns with the functions f(x) and g(x), resulting in the accurate intersection point (2, 4). Graph B does not accurately represent the functions based on the reported intersection point (4, 1).
The correct graph can be determined by analyzing the given functions and the specified intersection points. The functions are f(x) = -3/4 * x^2 + 3x + 1 and g(x) = 2x, and the reported intersection points are (2, 4) for graph A and (4, 1) for graph B.
To verify the accuracy, substitute the x-values into both functions:
Graph A (Intersection at (2, 4)):
f(2) = -3/4 * (2)^2 + 3 * 2 + 1 = 4
g(2) = 2 * 2 = 4
Both functions align, confirming the correctness of the reported intersection point.
Graph B (Intersection at (4, 1)):
f(4) = -3/4 * (4)^2 + 3 * 4 + 1 = 1
g(4) = 2 * 4 = 8
There is a discrepancy here, as the y-values do not match. Therefore, graph B does not accurately represent the functions f(x) and g(x).
In conclusion, graph A is correct since it accurately reflects the given functions and results in the reported intersection point (2, 4).
The percentage of Male workers who prefer a female boss over a male boss increased approximately linearly from 5% in 1974 to 9% in 1998. Predict when 9% of male workers will prefer a female boss.
The percentage of male workers who preferred a female boss increased at a rate of 0.1667% per year from 1974 to 1998. Using this information, we can predict that 9% of male workers would prefer a female boss in the year 1998.
Explanation:This question involves linear relationships and prediction in mathematics. In this case, we're looking at an increase from 5% to 9% in male workers who preferred a female boss--this increase occurred over a period of 24 years (from 1974 to 1998). So, the rate of increase in male workers who preferred a female boss over those years was (9% - 5%) / 24 years = 0.1667% per year. Since the percentage was 5% in the beginning year 1974, we need to find the year when this percentage will become 9%. So, 9% = 5% + 0.1667% * (number of years from 1974). Solving this for the number of years gives approximately 24 years. Therefore, the year when 9% of male workers will prefer a female boss would be 1974+24 = 1998

∫₋₂² (f(x) + 6) dx
Split the integral:
∫₋₂² f(x) dx + ∫₋₂² 6 dx
Graphically, if f(-x) = -f(x), then ∫₋₂² f(x) dx = 0. But we can also show this algebraically.
Split the first integral:
∫₋₂⁰ f(x) dx + ∫₀² f(x) dx + ∫₋₂² 6 dx
Using substitution, write the first integral in terms of -x.
∫₂⁰ f(-x) d(-x) + ∫₀² f(x) dx + ∫₋₂² 6 dx
-∫₂⁰ f(-x) dx + ∫₀² f(x) dx + ∫₋₂² 6 dx
Flip the limits and multiply by -1.

Alfred Juarez owns a small publishing house specializing in Latin American poetry. His fixed cost to produce a typical poetry volume is $525, and his total cost to produce 1000 copies of the book is $2675. His books sell for $4.95 each.
(A) Find the linear cost function for Alfred's book production.
(B) How many poetry books must he produce and sell in order to break even?
(C) How many books must he produce and sell to make a profit of $1000?
Answer:
(A) [tex]C(x)=2.15x+525[/tex]
(B) 188 books
(C) 545 books
Step-by-step explanation:
We have been given that Alfred Juarez's fixed cost to produce a typical poetry volume is $525, and his total cost to produce 1000 copies of the book is $2675.
(A) The cost function will be in form [tex]C(x)=ax+b[/tex], where, a is cost of each copy, x is number of books and b is fixed cost.
Upon substituting our given information, we will get:
[tex]2675=1000a+525[/tex]
Let us solve for a.
[tex]2675-525=1000a[/tex]
[tex]2150=1000a[/tex]
[tex]a=\frac{2150}{1000}=2.15[/tex]
Therefore, the cost function would be [tex]C(x)=2.15x+525[/tex].
(B) Since each book sells for $4.95, so amount earned by selling x books would be [tex]4.95x[/tex]
Revenue function would be [tex]R(x)=4.95x[/tex]
We know that break-even is a point, where cost is equal to revenue or when there is a 0 profit.
[tex]R(x)=C(x)\\\\4.95x=2.15x+525[/tex]
[tex]4.95x-2.15x=525[/tex]
[tex]2.8x=525[/tex]
[tex]x=\frac{525}{2.8}[/tex]
[tex]x=187.5\approx 188[/tex]
Therefore, Alfred must produce 188 poetry books to break even.
(C) We know that profit is equal to difference of revenue and cost.
[tex]\text{Profit}=\text{Revenue}-\text{Cost}[/tex]
[tex]P(x)=4.95x-(2.15x+525)[/tex]
[tex]1000=4.95x-(2.15x+525)[/tex]
[tex]1000=4.95x-2.15x-525[/tex]
[tex]1000=2.8x-525[/tex]
[tex]1000+525=2.8x[/tex]
[tex]1525=2.8x[/tex]
[tex]x=\frac{1525}{2.8}[/tex]
[tex]x=544.642857\approx 545[/tex]
Therefore, Alfred must produce and sell 545 books to make a profit of $1000.

The altitude of a model rocket launched into the air from a rooftop is given by the quadratic equation A(t) = −16t2 + 32t + 48, where t is the time in seconds since launch, and A is measured in feet. At what time does the rocket land on the ground?
Answer:
Rocket will land on the ground in 3 seconds.
Step-by-step explanation:
Given:
[tex]A(t) = -16t^2 + 32t + 48[/tex]
where [tex]t[/tex] ⇒ time in seconds since launch.
[tex]A(t)[/tex] ⇒ altitude of the rocket after reaching the ground.
we need to find the time at which rocket will land on the ground.
Solution:
Now we can say that;
altitude of the rocket after reaching the ground will be equal to 0.
So;
[tex]A(t)=0[/tex]
Now Substituting [tex]A(t)=0[/tex] in given expression we get;
[tex]0=-16t^2+32+48[/tex]
Now we take -16 common we get;
[tex]0=-16(t^2-2t-3)[/tex]
Now Dividing both side by -16 we get;
[tex]\frac0{-16}=\frac{-16(t^2-2t-3)}{-16}\\\\0=t^2-2t-3[/tex]
Now factorizing the above equation we get;
[tex]0=t^2-3t+t-3\\\\0=t(t-3)+1(t-3)\\\\0=(t+1)(t-3)[/tex]
Now we will find 2 values of t by substituting each separately.
[tex]t+1=0 \ \ \ Or \ \ \ \ t-3 =0\\\\t =-1 \ \ \ \ \ \ Or \ \ \ \ \ \ t=3[/tex]
Now we get 2 values of t one positive and one negative.
Now we know that time cannot e negative hence we will discard it and consider positive value of t.
Hence Rocket will land on the ground in 3 seconds.

A tire for a car is 24 inches in diameter. If the car is traveling at a speed of 60 mi/hr, find the number of revolutions the tire makes per minute. (Round your answer to the nearest hundredth.)
Answer: The number of revolutions the tire makes per minute= 840.76
Step-by-step explanation:
Given : Diameter of tire = 24 inches
Speed of car = 60 mi/ hr
We know that 1 mile =63360 inches and 1 hour = 60 minutes
Then, Speed of car = ( 60 mi/ hr) x( 63360 inches) ÷ (60 minutes)
[tex]=\dfrac{60\times63360 }{60}[/tex] inches/minute
=63360 inches / minute
Circumference of tire = [tex]\pi (diameter)[/tex]
[tex](3.14)(24)=75.36\ inches[/tex]
Now , the number of revolutions the tire makes per minute = [tex]\dfrac{\text{speed of car}}{\text{Circumference of tire}}[/tex]
[tex]=\dfrac{63360}{75.36}=840.76433121\approx840.76[/tex]
Hence, the number of revolutions the tire makes per minute= 840.76

Marilyn Mallinson invested $30000, part at 6% annual interest and the rest at 7.5% annual interest. Last year she earned $1995 in interest. How much money did she invest at each rate?
Answer: she invested $17000 in the account earning 6% annual interest.
she invested $13000 in the account earning 7.5% annual interest.
Step-by-step explanation:
Let x represent the amount that she invested in the account earning 6% annual interest.
Let y represent the amount that she invested in the account earning 7.5% annual interest.
Marilyn Mallinson invested $30000, part at 6% annual interest and the rest at 7.5% annual interest. This means that
x + y = 30000
The formula for determining simple interest is expressed as
I = PRT/100
Where
I represents interest paid on the loan.
P represents the principal or amount taken as loan
R represents interest rate
T represents the duration of the loan in years.
Considering the account earning 6% annual interest.
P = x
R = 6%
T = 1 year
I = (x × 6 × 1)/100 = 0.06x
Considering the account earning 7.5% annual interest,
P = y
R = 7.5
T = 1
I = (y × 7.5 × 1)/100 = 0.075y
Last year she earned $1995 in interest. This means that
0.06x + 0.075y = 1995 - - - - - - - -
Substituting x = 30000 - y into equation 1, it becomes
0.06(30000 - y) + 0.075y = 1995
1800 - 0.06y + 0.075y = 1995
- 0.06y + 0.075y = 1995 - 1800
0.015y = 195
y = 195/0.015 = 13000
x = 30000 - y = 30000 - 13000
x = 17000

7 cannot be subtracted from 5 so borrow a 10 to make it 7 subtracted from 15 and then the 8 tens becomes 7 tens so 7-2=5
58+27=85 to check your work
We need to regroup 1 ten as 10 ones by the problem; subtract 27 from 85
What is a numerical expression?A numerical expression is an algebraic information stated in the form of numbers and variables that are unknown. Information can is used to generate numerical expressions.
Given that regroup 1 ten as 10 one
85 -27 = 58
Since 7 cannot be subtracted from 5 so borrow a 10 to make it 7 subtracbecomem 15 and then the 8 tens becomes 7 tens thus, 7-2=5
Therefore,
58 + 27 = 85
We need to regroup 1 ten as 10 ones by the problem; subtract 27 from 85

In pea plants, smooth pea shape is dominant towrinkled and yellow pea color is dominant togreen. A plant that is heterozygous for pea shape and has green peas is crossed with a plant that is has wrinkled peas and is heterozygous forpeacolor. What is the probability of having offspringwith wrinkledgreen peas?
The probability of having wrinkled green peas is 25% or 0.25
Explanation:
Given:
Pea shape - smooth and wrinkled
Pea color - Yellow and green
Smooth is dominant to wrinkled
Yellow color is dominant to green
So, the genotype of smooth pea is SS or Ss
wrinkled pea is ss
The genotype of yellow pea is YY or Yy
green pea is yy
According to the question,
Ssyy X ssYy
Possible gametes of Ssyy - Sy , Sy, sy, sy
Possible gametes of ssYy - sY, sy, sY, sy
Cross between these gametes are shown in the punnett square drawn in the word file attached.
According to the cross,
The probability of having wrinkled green peas is 25% or 0.25
