Answer:

Area of base = 25cm

Step-by-step explanation:

The formula for the volume of a rectangular prism is:

Volume = length × width × height = lwh

for a square base, length = width

∴ volume = l × l × h = l²h

where:

l = length

h = height = 9cm

volume = 225 cm³

∴ 225 = l² × 9

l² = 225 ÷ 9

l² =  25

∴ length = √ 25 = 5cm

Area of base = Length × Length = 5 × 5 = 25cm

Answer:

150 square feet

Step-by-step explanation:

Step 1

Find the Length and Width of the backyard

The length of a rectangular backyard is 5 feet longer than the width of the backyard. The perimeter of the backyard is 50 feet.

Perimeter = 2L + 2W

L = Length, W = Width

L = 5 + W

Hence:

50 = 2(5 + W) + 2W

50 = 10 + 2W + 2W

Collect like terms

50 - 10 = 4W

40 = 4W

W = 40/4

W = 10 feet

We find L

L = 5 + W

L = 5 + 10 feet

L = 15 feet

Step 2

What is the area of the backyard?

Area of a rectangle = Length × Width

Area of the rectangular backyard = 15 feet × 10 feet

= 150 square feet

Answer: Exponential, and increases by 343 percent.

Step-by-step explanation: Always depends on the number being raised, let's call it B. If B is between 0 and 1, it's a decay, but if B is greater than 1, it is exponential. In this case, B is 7, therefore it's exponential.

Answer:

System of equations:

L = 5W + 7

2W + 2L = P

L = 62 cm

W = 11 cm

Step-by-step explanation:

Given the measurements and key words/phrases in the problem, we can set up two different equations that can be used to find both variables, length and width, of the rectangle.  

The formula for perimeter of a rectangle is:  2W + 2L = P, where W = width and L = length.  We also know that the L is '7 more than five times its width'.  This can be written as:  L = 5W + 7.  Using this expression for the value of 'L', we can use the formula for perimeter and solve for width:

2W + 2(5W + 7) = 146

Distribute:  2W + 10W + 14 = 146

Combine like terms:  12W + 14 = 146

Subtract 14 from both sides:  12W + 14 - 14 = 146 - 14 or 12W = 132

Divide 12 by both sides:  12W/12 = 132/12 or W = 11

Put '11' in for W in the equation for 'L':  L = 5(11) + 7 or L = 55 + 7 = 62.

Answer:

15 meals and 35 drinks

Step-by-step explanation:

m + d = 50

5m+ 2d=145

2m+ 2d = 100

5m+ 2d =145

3m=45

m=15

15+d=50

d=35

Step-by-step explanation:

I think you mean solve for x

Set up a proportion.

The proportion should be set up as

Large Parts of ADE = Similar Parts of ABC

DE/BC = AD/AB

DE = x

BC = 6

AD = 20

AB = 10

x/6 = 20/10                Multiply by 6

x = 20*6 / 10

x = 120 / 10

x = 12

Answer:

Jack's new balance is: 397.51.

Step-by-step explanation:

With the information provided, first you can find the unpaid balance using the following formula:

Unpaid balance=Previous balance-payments

Unpaid balance=95.85-45

Unpaid balance=50.85

Then, you can calculate the finance charge by multiplying the unpaid balance for the finance rate:

Finance charge=50.85*1.5%

Finance charge=0.76

Finally, you can find the new balance by adding up the unpaid balance plus the finance charge plus the new charges:

New balance=50.85+0.76+345.90

New balance=397.51

According to this, the answer is that Jack's new balance is: 397.51.

Answer:

118.73

Step-by-step explanation:

Answer:

118.74 ft²

Step-by-step explanation:

First, you're going to get the are of the following shapes, one by one.

Area of A Circle = πr²

Area of a Rectangle = bh

Area of a Square = s²

Step 1: Let's find the area for the Circle.

Diameter = 6

Radius = Diameter ÷ 2

6 ÷ 2 = 3

The Radius is 3.

A = (3.14)(3)²

Simplify:

(3.14)(9) = 28.26 ft²

Step 2: Find the Area of the Rectangle.

A = bh

11 × 2 = 22

Area of Rectangle = 22 ft²

Step 3: Find the Area of the Square

A = s²

13² = 13 × 13 = 169 ft²

Step 4: Subtract the Aea of the Circle and Rectangle form the Are of the Square.

169 - 28.26 - 22 = 118.74 ft²

Answer:  Six hundred thirty-one thousandths.

Answer:

Six hundred thirty-one thousandths.

Step-by-step explanation:

Answer:

158 quarters

54 dimes

Step-by-step explanation:

Let d = no. of dimes

     q = no. of quarters

10d = value of all the dimes since each dime is worth 10 cents

and 25q = value of all the quarters since each quarter is worth 25 cents

$44.90 = 4490 cents

  10d + 25q = 4490              d + q = 212

- 10d - 10q = -2120

             15q = 2370

                 q = 158 quarters   d + 158 = 212

                                                        d = 54 dimes
