Answer:
80 yd^2
Step-by-step explanation:
Since the formula for squares is s^2, we can use this to set up an equation, which is
s^2=400
If we square root this, we get
s=20
The perimeter formula for a square is 4s, so if we plug in, we end up with 80 yd^2

If f(x) and r1(x) are inverse functions of each other and f(x)=2x+5 , what is f^-1(8) ?
PLEASE HELP!!
Answer:
3/2
Step-by-step explanation:
Given y = 2x + 5, let's rewrite the equation in terms of x;
y = 2x + 5 => Bring 5 to the other side
2x = y - 5 => Divide either side by 2
x = (y - 5)/2
If we want to take the inverse, simply swap the variable's positions...
We have y = (x - 5)/2
Now let's determine f^-1(8), substituting for "y" provided y is our inverse, f^-1
f^-1(8) = (8 - 5)/2 = 3/2
Solution: 3/2

What do degrees measure?
A. The type of angle
B. The length
C. The orientation
D. The incline
The degrees measure the incline because the degree measures an angle which is the measure of incline option (D) is correct.
What is an angle?When two lines or rays converge at the same point, the measurement between them is called an "Angle."
It is given that:
The measuring unit is the degree
The measurement can be defined as the numerical quantity that gives an idea about object length, width, and many more. It can be used to compare two objects.
As we know from the definition of the angle; two lines or rays converge at the same point, and the measurement between them is called an "Angle."
The degree measures an angle which is the measure of incline.
Thus, the degrees measure the incline because the degree measures an angle which is the measure of incline option (D) is correct.

24 __ 3/4 = 18 is it Multiplication Division Addition Subtraction
Answer:
Multiplication
Step-by-step explanation:
Calculator
Multiplication is the required operation.
What is the BODMAS rule?According to the BODMAS rule, the brackets have to be solved first followed by powers or roots (i.e. of), then Division, Multiplication, Addition, and at the end Subtraction. Solving any expression is considered correct only if the BODMAS rule or the PEMDAS rule is followed to solve it.
Given here: The equation given is 24_ 3/4=18
Let the operation be multiplication then we get
24×3/4=6×3
=18
Similarly, we can verify that no other operation yields the answer an s18 and thus the operation performed must be multiplication.
Hence, Multiplication is the required operation.

Jason spent a total of $131 on shirts. Dress shirts cost $28 dollars and T-shirts cost $15 dollars. If he brought 7 shirts how many of each kind did he buy?
Answer: 28x + 15y = 131 and x + y = 7 where x is the number of Dress shirt and y is the number of T-shirt.
Step-by-step explanation:
We will represent the number of Dress shirt he bought by x and we will represent the number of T-shirt he bought by y.
We know that he spent 131 so the cost of each dress shirt plus the cost of each T-shirt has to equal 131. Also, he bought 7 total shirts so x plus y has to equal 7.
28x + 15y = 131
x + y = 7
Note: it says don't solve so I didn't solve but if you want to solve use these equations.
