Answer:

(y-6)/(4+r)=x

Step-by-step explanation:

y=4x+rx+6

y-6=4x+rx

y-6=x(4+r)

divide both sides by (4+r)

(y-6)/(4+r)=x

Margie did math homework for 25 minutes science homework for 60 minutes and took a break for 15 minutes write a percent to repre

kaheart [24]

Answer:

Margie spent 60% of time in doing science Homework

Step-by-step explanation:

Given:

Time spent in doing maths homework = 25 minutes

Time spent in doing science homework = 60 minutes

Break Time = 15 minutes

To Find:

A percent to represent the portion of time that Margie spent on science homework = ?

Solution:

Let the portion representing the portion of time that Margie spent on science homework be x

The total time spent in doing both maths and science homework and in break time = Time spent in doing maths homework + Time spent in doing science homework + Break Time

The total time spent in doing both maths and science homework and in break time = 25 +60 +15 = 100 minutes

Then

x = $\frac{\text{time spent in doing science home work}}{\text{total time spent}} \times 100$

x = $\frac{60}{100} \times 100$

x = 60%

The density of granite is about 2.75 grams per cubic centimeter. Suppose you have a granite countertop for a kitchen that is 1 m

Ugo [173]

Answer:

equation: 2.75 g/cm^3 * 1 m *3 m* (100 cm/1 m)^2 *4 cm * (1 kg/1000 g)

Step-by-step explanation:

countertop mass, m =?

density, ρ = 2.75 g/cm^3

wide, w = 1 m

long, l = 3 m

thick, t = 4 cm

countertop volume, V = w*l*t = 1 m *3 m*4 cm* (100 cm/1 m)^2

Isolating mass from density definition gives

ρ = m/V

m = ρ*V

m = 2.75 g/cm^3 * 1 m *3 m* (100 cm/1 m)^2 *4 cm * (1 kg/1000 g)
