Answer:

9.09%

Step-by-step explanation:

You over estimated by 2 feet. Find out how much 2 feet of 22 is by dividing 2 by 22...

2/22 = 0.090909090909

To convert a decimal to a percent, multiply the decimal by 100%

0.0909090909(100%) = 9.0909090909% or 9.09%

Y would be 3 then.
Beacuse the equation is y=Mx+c
So if you substitute the values it will be
y=2(0)+3
Y=0+3
Y=3

Cara and Jena, working together, can clean the house in 4

kirill115 [55]

Answer:

$\frac{4}{3}$ hrs/house

Step-by-step explanation:

Rate is the amount of work done per unit of time;

Let Cara's rate = C

Let Jena's rate = J

C + J = 4 ------ i

Now;

Working alone:

Jena takes twice as long as Cara

J = 2C ---- i

How long does it take Cara to clean a house alone

C + J = 4

J = 2C

C + 2C = 4

3C = 4

C = $\frac{4}{3}$ hrs/house
