Andrew has 212 coins, all of
which are either quarters or
dimes. The total value of the
coins is $44.90. What is the
value of all of the dimes?
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

The graph of y = f(x) is shown below. Determine the value of x when f(x) = 2?
The value of x when f(x) = 2 is 0.
When you replace f(x) with 2 you get y = 2.
Thus, you graph y = 2 and you get the following image below.

A right rectangular prism has a square base and a volume of 225 cubic centimeters. The height, h, of the prism is 9 centimeters. Find the area of the base, B. A. B. C. D.
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

Frank decided to keep track of his sleep using a fitness tracker. He was surprised to
learn that there was 21 minutes of awake time during the seven hours when he was
supposed to be asleep at night. What percentage of the seven hours was Frank awake during the night?
%
Answer: 5%
Step-by-step explanation:
First and foremost, we need to know that 60 minutes = 1 hour. Therefore,
7 hours = 60 × 7 = 420 minutes.
Number of minutes awake = 21 minutes
Number of minutes supposed to be asleep = 7 hours = 420 minutes
The percentage of the seven hours that Frank was awake during the night will be:
= 21/420 × 100
= 1/20 × 100.
= 5%
The length of a rectangular backyard is 5 feet longer than the width of the backyard. The perimeter of the backyard is 50 feet. What is the area of the backyard?
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:
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

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
