Answer: 4

Step-by-step explanation:

4^2=16

Answer:

4

Step-by-step explanation:

When we square something we just multiply it by itself.

2 x 2 = 4 so not 2

3 x 3 = 9 so not 3 either

4 x 4 = 16 this one is correct!

8 x 8 = 64 not this one either

So the answer is 4 BOOM

Answer:

Answer:

A down payment of $5,388.50  to get the principle to $19611.50  for a monthly payment of $400 for 60 months at 8.25%

Step-by-step explanation:

I used a payment calculator

I don't know how else to solve the problem.  I thought I could find the equation, but I don't think this is it, since P didn't equal 19611.50

A = P[r(1+r)n] / [(1+r)n - 1]    

if you have the correct formula follow this process

A = 400        P principle ???    r = i%/12 = 0.0825/12 =  0.006875    n= 5×12 = 60

     solve for P      then    down payment = 25000 - P

 P = A / [r(1+r)n] / [(1+r)n - 1]    

    = A [(1+r)n - 1]  /  [r(1+r)n]

    =  400 [(1 +.006875)60 -1]  /  [0.006875( 1 +0.006875)60]

Answer:

A) y = x²- x

Step-by-step explanation:

A linear function will have y equal to x, without x being manipulated by a square root, exponent, etc.

y = x²- x has x being squared.

This will create a graph of a parabola, which is not linear.

So, since it is a quadratic instead of a line, answer choice A) y = x²- x is correct.

Answer:

36 cm^2 is the area

Explanation -->

- first, separate the polygon into two separate ones, horizontally, to make two rectangles

- NOTE : Area = length x width

- 6 times 4 = 24

- 4 times 3 = 12  (self-explanatory, you get 4 by subtracting 6 and 2, as you can see)

- 24 + 12 = 36

-- You get 36 cm^2 --

The volume of the given cone is 718.01 square feet. Therefore, option H is the correct answer.

The volume of a cone is the amount of space occupied by a cone in a three-dimensional plane. A cone has a circular base, which means the base is made of a radius and diameter. The volume of a cone formula is 1/3 πr²h.

Given that, radius of a base of cone is 7 feet.

A height of a cone equal to its diameter = 7×2 = 14 feet

Here, volume of a cone = 1/3 ×3.14×7²×14

= 718.01 square feet

Therefore, option H is the correct answer.

Step-by-step explanation:

Answer:

Carl buys 132.475 liters of water.

Step-by-step explanation:

Since Carl buys seven 5-gallon jugs of water multiply 7 by 5 to know how many gallons of water Carl bought in total.

7(5) = 35 Gallons

Now that you have the total amount of gallons of water Carl bought you have to convert 35 gallons to liters given that 1 gallon = 3.785 liters by multiplying 35 by 3.785.

35(3.785) = 132.475

So Carl bought 132.475 liters of water.

Though that is the answer based on what is given a gallon is actually equal to 3.78541 liters so the exact answer would be 132.489 liters of water.

There is 1820 ways of teams of 4 can she make without repetition using combination formula.

What is combination?

  Selections are another name for combinations. The choice of items from a predetermined group of items corresponds to combinations. We don't want to organise anything here. We are going to choose them. We use the notation nCr to indicate how many distinct r-selections or combinations there are among a set of n objects. A combination is distinct from an arrangement or a permutation. No matter how the objects are arranged, combinations are produced by choosing some or all of them.

Here There are 16 total swim team members and 4 swimmers that will be chosen for each relay team.

So, n=16 and r=4. Then

=> nCr =  [tex]\frac{n!}{r!(n-r)!}[/tex]

=> 16C4 = [tex]\frac{16!}{4!(16-4)!}[/tex]

=> 16C4 = [tex]\frac{16!}{4!*12!}[/tex]

=> 16C4 = [tex]\frac{16*15*14*13}{4*3*2*1}[/tex]

=>16C4 = 4*5*7*13 = 1820

Hence there is 1820 ways  of teams of 4 can she make without repetition.

how to calculate percentage of a number. Use the percentage formula: P% * X = Y

Convert the problem to an equation using the percentage formula: P% * X = Y.

P is 10%, X is 150, so the equation is 10% * 150 = Y.

Convert 10% to a decimal by removing the percent sign and dividing by 100: 10/100 = 0.10.
