Answer:
B) Find the ratio of minutes to miles, 4:1. Multiply 7.5 by 4
Step-by-step explanation:
A bicyclist rides the same number of miles every minute. The ratio table below shows the number of miles she rides during certain amounts of time.
Biking Times and Distances
Number of Minutes Number of Miles
10 2.5
16 4
? 7.5
48 12
Which statement explains how to find the number of minutes it takes to bike 7.5 miles?
B) Find the ratio of minutes to miles, 4:1. Multiply 7.5 by 4....
Gross income : 785 per week
deductions are :
FICA : 42.25
income tax : 90.33
2% state tax : 0.02(785) = 15.70
1% city tax : 0.01(785) = 7.85
3% retirement : 0.03(785) = 23.55
total deductions are : 42.25+90.33+15.70+7.85+23.55 = 179.68
gross pay - deductions = net pay
785 - 179.68 = net pay
605.32 = net pay <====
Answer:
Multiply both sides of the equation by 3 and then divide both sides by 2. The standard form of the equation is 6x – y = 12.
Step-by-step explanation:
Katarina's equation
4x - 2/3y = 8
In order to convert Katrina's linear equation into standard form,
She should find the least common denominator
4x - 2/3y = 8
{4x(3) - 2y(1)} / 3 = 8
(12x - 2y) / 3 = 8
Multiply both sides by 3
(12x - 2y) / 3 × 3 = 8 × 3
12x - 2y = 24
Divide both sides by 2
(12x - 2y) / 2 = 24 / 2
6x - y = 12
The advice sofiya gave Katrina is to Multiply both sides of the equation by 3 and then divide both sides by 2. The standard form of the equation is 6x – y = 12.

Answer:
Hello! Your answer is D: 75.
Step-by-step explanation:
First we need to find the volume of pyramid A in order to solve this problem:
The formula for the pyramid is: V=
(B)(h)
Now we plug in the numbers:
V=(81)(4)
V=(324)
V=108in³
Now we divide pyramid B's volume by pyramid A's:
8,100/108 = 75
So the volume pyramid B is 75 times bigger than the volume of pyramid A!
Hope this helps!
