Answer:
[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].

5y = 4x + 8
{(-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]
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.
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

Sam invests $6000 in an account that pays interest of 4.5% per year.
a) How much interest would he earn each year?
b) How much would he have in his account at the end of the first year?
He would earn an interest of $270 each year and at the end of the first year he would have $6270 in his account.
Step-by-step explanation:
Step 1: Given details are Principal Amount (P) = $6000, Rate of Interest (R) = 4.5% and time (T) = 1 yearStep 2: Calculate simple interest by using the formula SI = PRT/100⇒ SI = 6000 × 4.5 × 1/100
⇒ SI = 60 × 4.5 = $270
Step 3: Calculate the amount he would receive at the end of an year by using the formula, A = P + SI⇒ A = 6000 + 270
⇒ A = $6270

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

What is the final amount if 943 is decreased by 13% followed by a further 6% decrease?
Give your answer rounded to 2 DP.
The final amount after a 13% decrease followed by a further 6% decrease from 943, rounded to two decimal places, is 771.19.
Explanation:To calculate the final amount after sequential percentage decreases, you first apply the initial percentage decrease to the original amount, then apply the second percentage decrease to the new, lower amount.
Here’s how you can do it step by step:
Calculate the first decrease of 13%: 943 × 0.13 = 122.59Subtract the first decrease from the original amount: 943 - 122.59 = 820.41Calculate the second decrease of 6% on the new amount: 820.41 × 0.06 = 49.2246Subtract the second decrease from the new amount: 820.41 - 49.2246 = 771.1854The calculator answer is 771.1854, but since we want the answer rounded to two decimal places, we must look at the third decimal place. Since the digit in the thousandths place (5) is greater than or equal to 5, we round up giving us a final answer of 771.19.

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.
The graphs of f(x) and g(x) are shown below.
On a coordinate plane, a straight line with negative a slope represents f (x) = negative x. The line goes through points (0, 0), (negative 6, 6) and (6, negative 6). On a coordinate plane, a straight line with a positive slope represents g (x) = 2 x. The line goes through points (negative 3, negative 6), (0, 0) and (3, 6).
Which of the following is the graph of (g – f)(x)?
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]
Option C is true.

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.
