If the side-length is 9, we can do:
A = 9²
A = 81 m²
Step-by-step explanation:
Step 1: Find the area

Find the interest on $4,500 at 5.2% for 2 and a half years. Which of the following equations would be used to solve this problem?
Please help!
A: 4500 = P(0.052)(2.5)
B: I = (4500)(5.2)(2.5)
C: I = (4500)(0.052)(2.5)
D: I = (4500)(0.52)(2.5)
The equations used to solve this problem is I = (4500)(0.052)(2.5).
The correct option is (C).
What is Interest?Simple interest is a loan interest payment that borrowers pay to lenders. It is based solely on the principal and does not account for compounding interest. Straightforward interest is not limited to certain loans. It is also the form of interest that banks pay on savings accounts.
Given:
P = $4500
R= 5.2%
Time= 2 and half year
Using the formula of Simple Interest
= P x R x T / 100
= (4500 x 5.2 x 2.5)/ 100
= (4500 x 0.052 x 2.5)
= $585
So, the equation is: : I = (4500)(0.052)(2.5)

A movie theature offers two containers. One container is a traiangular prism with a base area of 12cm and 19 cm of height, for $6.75. The other is a rectangular prism with a base area of 8cm and a height of 15cm, for $6.25. Which container is the better value? Use 3.14 as an approximation for pie
Answer:
rectangular container
Step-by-step explanation:
Triangular prism area: A = 1/3 * base area * height
= 1/3 * 12 * 19
= 76 cm²
Rectangular prism: A = base area * height
= 8 * 15
= 120 cm²
The rectangular container has a better value because it has a bigger area and is cheaper.

A chemical company mixes pure water with their premium antifreeze solution to create an inexpensive antifreeze mixture. The premium antifreeze solution contains
80
%
pure antifreeze. The company wants to obtain
320
gallons of a mixture that contains
55
%
pure antifreeze. How many gallons of water and how many gallons of the premium antifreeze solution must be mixed?
Answer:
let w = amt of water required
:
An equation based on the the percent water, an 80% solution is 20% water.
.20(320-w) + w = .50(320)
64 - .2w + w = 160
.8w = 160 - 64
w = 96%2F.8
w = 120 gal of water to produce 320 gal of 50% antifreeze
:
320 - 120 = 200 gal of 80% solution
Water: _120___ gallons
Premium Antifreeze: __200___ gallons

Answer:
k = 5,
y = 5x
Step-by-step explanation:
If y is proportional to x,
y ∝ x
Then the equation will be
y = kx
Her k = proportionality constant.
Now we choose a point from the given table.
Let the point is (2, 10).
By putting the values of x and y in the equation,
10 = 2×k
k = [tex]\frac{10}{2}[/tex]
k = 5
This will be true for any point we choose from the table.
And the equation will be y = 5x

Martin made 12 out of 40 shots during the basketball game. What percent of his shots did he make?
Answer:
30 percent
Step-by-step explanation:
12/40=0.3
0.3=30 percent
Answer:
30%
Step-by-step explanation:
To find a percent, use this equation:
x/100 = n/t
where x is the percent, n is the select number of things, and t is the total number of things
Substitute:
x/100 = n/t
x/100 = number of shots Marin made/number of shots attempted
x/100 = 12/40
Now, we need to cross multiply, or multiply the numerators by the denominators of the other fraction, and vice versa.
Multiply:
x/100 = 12/40
x(40) = 40x
100(12) = 1200
40x = 1200
Now, divide both sides of the equation to find the value of x.
Divide:
40x = 1200
/40 /40
x = 30
Now we have the percent is fraction form: 30/100
To make it a percentage, simply take the numerator and add the % sign.
Therefore, Martin made 30% of his shots.

A linear system is classified as inconsistent. Choose True or False for the statement about the graph of the system.The slopes of the lines are the same.
Answer: true
Step-by-step explanation:
A system of linear equations can be written as:
y = a*x + c
y = d*x + f
Now, the idea of this is find the point (x, y) where both linear equations meet.
Particularlly, if the slope in both equations is the same, we will have two options:
1) The lines are parallel, so they never met, and the system has no solution.
2) The lines are the same lines (this happens when c = f) and this means that we have infinite solutions.
So it is true, if the slopes are the same, the linear system is not consisten.
