[tex]Area\ of\ a\ trinagle = \frac{5}{12}x^2[/tex] [tex]or\ 0.42x^2[/tex]
Step-by-step explanation:
Given:
Height of the triangle [tex]h = x[/tex]
Base of the triangle [tex]b=\frac{5}{6}x[/tex]
We need to find the area of the triangle.
Solution:
Using given Formula:
[tex]Area\ of\ a\ trinagle = \frac{1}{2}bh[/tex]
Where:
b = Base of the triangle.
h = Height of the triangle.
Substitute [tex]h = x[/tex] and [tex]b=\frac{5}{6}x[/tex] in equation in given formula.
[tex]Area\ of\ a\ trinagle = \frac{1}{2}(\frac{5}{6})x\times x[/tex]
[tex]Area\ of\ a\ trinagle = \frac{5}{12}x^2[/tex]
[tex]Area\ of\ a\ trinagle =0.42x^2[/tex]
Therefore, Area of the triangle is [tex]\frac{5}{12}x^2[/tex] or [tex]0.42x^2[/tex].

{(-34/7, -16/7)}
{(-34/7, 16/7)}
{(34/7, -16/7)}
Answer:
{(-34/7, -16/7)}
Step-by-step explanation:
Rearrange values, multiply to solve for x.
(5) 2y = 3x + 10
(-2) 5y = 4x + 8
Solve for x.
10y = 15x + 50 ↓
-10y = -8x -16
Combine and evaluate.
0 = 7x + 34
Subtract 34 from both sides.
7x = -34
Divide both sides by 7.
x = [tex]\frac{-34}{7}[/tex]
Plugin x value into either equation to solve for y.
2y = (3 × [tex]\frac{-34}{7}[/tex]) + 10
2y = [tex]\frac{-102}{7}[/tex] + 10
2y = [tex]\frac{-32}{7}[/tex]
y = [tex]\frac{-16}{7}[/tex]
The ratio of faculty members to students at a college is 1:15. If there are 675 students, then how many faculty members are there?
Answer:
The number of faculty member is 45.
Step-by-step explanation:
Ratio of faculty members to students = 1 : 15
Number of students = 675
Total = Number students + faculty members
Let the total be t
Let the faculty member be f
Representing the ratio, we have:
[tex]\frac{15}{16} * t = 675\\\frac{15t}{16} = 675\\15t = 16 * 675\\15t = 10800\\\frac{15t}{15} =\frac{10800}{15} \\t = 720[/tex]
Therefore, the total number of both the students and faculty member is 720. To get the number of faculty member:
Total = Number students + faculty members
[tex]720 = 675 + f\\f = 720 - 675\\f = 45[/tex]
The number of faculty member is 45.

-3t-8+7t =34 +9t -2
Solve for t
Please give an exposition
Answer:
t = -8
Step-by-step explanation:
combine like terms, so -3t + 7t = 4t and 34 - 2 = 32
so 4t - 8 = 32 + 9t
then subtract 4t from both sides and subtract 32 from both sides. You will get: -40 = 5t.
Then divide both sides by 5 so you will get -8 = t
Answer: t= -8
Step-by-step explanation:
3t-8+7t=34+9t-2-3t+7t-8=9t+32-24t-8=9t+32t= -8You have decided to purchase a new Toyota 4Runner for $25,635. You have promised your daughter that the SUV will be hers when the car is worth $10,000. According to your car dealer, the SUV will depreciate in value approximately $3000 per year.
a) Write a linear equation in which y represents the total value of the car and x represents the age of the car,
The linear equation representing the value of the car as it depreciates over time is y = -3,000x + 25,635, where y is the value of the car and x is the age of the car in years.
To write a linear equation that describes the depreciation of the SUV over time, we define two variables: y represents the total value of the car at any time x, where x represents the age of the car in years.
The car is purchased for $25,635 and depreciates at a rate of $3,000 per year, which means that the value of the car decreases by a constant amount each year. We can write this situation as a linear function:
Linear Depreciation Equation:
y = -3,000x + 25,635
Here, the y-intercept is $25,635 (the value of the car at the time of purchase when x is zero), and the slope is -$3,000 (the rate at which the value of the car decreases per year).

The two triangles [tex]\triangle MNP\sim \triangle RST[/tex].
Therefore the corresponding sides are proportional.
[tex]\frac{|ST|}{|PN|} =\frac{|TR|}{|MP|}[/tex]
From the diagram |MP|=4, |PN|=3, |MN|=5 |ST|=x and |TR|=12.
Let us substitute the values and solve for x.
[tex]\frac{12}{4}=\frac{x}{3}[/tex]
Multiply both sides by 3 to get:
[tex]3*\frac{12}{4}=\frac{x}{3}*3[/tex]
This implies that:
[tex]9=x[/tex]
Therefore x=9

Together, teammates Pedro and Ricky got 2693 base hits last season. Pedro had 283 more
hits than Ricky. How many hits did each player have?
Answer: Pedro= 1205. Ricky= 1488
Step-by-step explanation:
It is found that Ricky hits 1202 base and Pedro hits = 1485 base
What is an equation?An equation is an expression that shows the relationship between two or more numbers and variables.
A mathematical equation is a statement with two equal sides and an equal sign in between. An equation is, for instance, 4 + 6 = 10. Both 4 + 6 and 10 can be seen on the left and right sides of the equal sign, respectively.
Given that
Pedro + Ricky = 2693 hits
Let Ricky hits = x
So, the Pedro hits will be = x + 283
( x + 283 ) + x = 2693
2 x + 283 = 2693
2 x = 2693 - 283
2 x = 2404
x = 1202
So, the Ricky hits 1202 base
Thus Pedro hits (1202 + 283) = 1485 base

Explain why dividing by a fraction results in the same answer as multiplying by its reciprocal.
Answer:
lets consider an example like
20 divided by 2/4 so we can rewrite as
2/4* x =20
so , 2* x =20*4
2* x =80
x=80/2
x=40
similarly,we can write the fraction as (20*4/2)-we can see that reciprocal of the fraction 2/4 is 4/2
x=20*4/2=80/2=40
so, we can say that dividing by a fraction results in the same answer as multiplying by its reciprocal.
At the zoo, the Spencer family bought 3 adult tickets and 2 children's tickets for $23.50. The Yang family bought 2 adult tickets and 4 children's tickets for $25. How much would the Diaz family spend if they bought 3 adults tickets and 1 children's ticket?
Diaz family spend $ 20 if they bought 3 adults tickets and 1 children's ticket
Solution:
Let "a" be the cost of each adult ticket
Let "c" be the cost of each student ticket
The Spencer family bought 3 adult tickets and 2 children's tickets for $23.50
Therefore, we frame a equation as:
[tex]3 \times a + 2 \times c = 23.50[/tex]
3a + 2c = 23.50 --------- eqn 1
The Yang family bought 2 adult tickets and 4 children's tickets for $25
Therefore, we frame a equation as:
[tex]2 \times a + 4 \times c = 25[/tex]
2a + 4c = 25 ----------- eqn 2
Let us solve eqn 1 and eqn 2
Multiply eqn 1 by 2
6a + 4c = 47 ---------- eqn 3
Subtract eqn 2 from eqn 3
6a + 4c = 47
2a + 4c = 25
( - ) --------------
4a = 47 - 25
4a = 22
Divide both sides of equation by 4
a = 5.5
Substitute a = 5.5 in eqn 1
3(5.5) + 2c = 23.50
16.5 + 2c = 23.50
2c = 23.50 - 16.5
2c = 7
Divide both sides of equation by 2
c = 3.5
Thus, cost of each adult ticket = $ 5.5
Cost of each student ticket = $ 3.5
How much would the Diaz family spend if they bought 3 adults tickets and 1 children's ticket?
Total cost = 3a + 1c
Total cost = 3(5.5) + 1(3.5) = 16.5 + 3.5
Total cost = 20
Thus Diaz family spend $ 20
Final answer:
The Diaz family would spend $20 for 3 adult tickets and 1 children's ticket at the zoo after solving the system of linear equations given by the Spencer and Yang families' purchases.
Explanation:
Let A be the price of an adult ticket and C be the price of a children's ticket. We are given:
3A + 2C = $23.50 (Spencer family)
2A + 4C = $25 (Yang family)
To solve this system, we can multiply the first equation by 2 and the second equation by 3:
6A + 4C = $47 (Spencer family doubled)
6A + 12C = $75 (Yang family tripled)
Subtracting the first equation from the second gives us:
8C = $28
Dividing both sides by 8 yields:
C = $3.50
Now that we know the price of a children's ticket, we can substitute this value back into one of the original equations to find the price of an adult ticket.
3A + 2(3.50) = $23.50
3A + $7 = $23.50
3A = $16.50
A = $5.50
With the price of both ticket types known, we can now calculate the cost for the Diaz family:
3A + 1C = 3($5.50) + 1($3.50)
3A + 1C = $16.50 + $3.50
3A + 1C = $20
Therefore, the Diaz family would spend $20 if they bought 3 adult tickets and 1 children's ticket.

Answer:
9 1/3, 12 1/2, 14 3/4
Step-by-step explanation:
I assume the formula you’re working with is A=b*h since nothing says otherwise...
((Patio 1))
So you have your area (147) and your base (15 3/4), now you need to plug them in, which should look like this:
147= 15 3/4*h
You need to isolate your h in order to get the missing number, so you should divide both sides by 15 3/4 OR 63/4 ((15*3—>60+3=63))
Dividing by a fraction is the equivalent of multiplying by its reciprocal... so
147 * 4/63 = 588/63 which can be simplified to 84/9 once both the numerator and denominator are divided by 7
In mixed number for it is 9 3/9 which simplified becomes 9 1/3
You solve the other similarly

On a coordinate plane, a straight line with a negative slope goes through points (negative 2, 6), (0, 0), and (2, negative 6)
On a coordinate plane, a straight line with a negative slope goes through points (negative 6, 6), (0, 0), and (6, negative 6).
On a coordinate plane, a straight line with a positive slope goes through points (negative 2, negative 6), (0, 0), and (2, 6).
On a coordinate plane, a straight line with a positive slope goes through points (negative 6, negative 6), (0, 0), and (6, 6).
Answer:
Option C
Step-by-step explanation:
We are given that
[tex]f(x)=-x[/tex]
The line passing through the points (0,0),(-6,6) and (6,-6).
[tex]g(x)=2x[/tex]
The line passing through the points (-3,-6),(0,0) and (3,6).
We have to find the graph of (g-f)(x).
[tex](g-f)(x)=g(x)-f(x)=2x-(-x)=2x+x[/tex]
[tex](g-f)(x)=3x[/tex]
Substitute x=0
[tex](g-f)(0)=3(0)=0[/tex]
[tex](g-f)(2)=3(2)=6[/tex]
[tex](g-f)(-2)=3(-2)=-6[/tex]
[tex](g-f)(-6)=3(-6)=-18[/tex]

Ava’s aquarium is 95% filled with water. The tank holds 1,120 gallons of water. Which is the remaining number of gallons of water needed to fill the aquarium to the top?
Answer:
The aquarium needs 56 more gallons to be completely filled.
Step-by-step explanation:
To get the amount remaining you have to first divide 1120 by 100
1120/100=11.2
Then multiply it by 95
11.2*95=1064
You take the maximum amount (1120) and subtract the amount in the tank (1064) to get the amount left.
1120-1064= 56
With 56 gallons as your final answer.
