Equation for company a: y=20x+8
Equation for company b: y=24x+4
Company A would be cheaper for 5 loads of laundry, because it is $108 dollars opposed to $124 which is what company b would charge for 5 loads.
$32 dollars is saved by using the services of company A instead of company B to clean 9 loads of laundry.
Answer: Amount that they paid in 2007 is 1.01 millions.
Step-by-step explanation:
Since we have given that
Number of millions paid last month = $1.29 millions
According to question, it was 26% above what they paid in 2007.
Let the amount paid in 2007 be x
So, our equation becomes,
Hence, Amount that they paid in 2007 is 1.01 millions.
Answer:
<h3>3cm</h3>
Step-by-step explanation:
Area of a triangle = 1/2 * base * height
Given
Area = 7 7/8cm²
Base = 5 1/4 cm
Required
Height of the triangle
Substitute;
7 7/8 = 1/2 * 5 1/4 * Height
63/8 = 1/2 * 21/4 * h
63/8 = 21H/8
63 = 21H
H = 63/21
H = 3cm
Hence the length of h is 3cm

Answer:
The answer to your question is Circumference = 81.64 ft
Step-by-step explanation:
Data
Area of a circle = 530.66 ft²
Circumference = ?
π = 3.14
Process
1.- Calculate the radius of the circle
Area = πr²
-Solve for r²
r² = Area / π
-Substitution
r² = 530.66 / 3.14
-Simplification
r² = 169
-result
r = 13 ft
2.- Calculate the Circumference
Circumference = 2πr
-Substitution
Circumference = 2(3.14)(13)
-Result
Circumference = 81.64 ft
