Given width is 24 less than length.
W=L-24
Perimeter = 2(W+L)=2(L-24+L)=4L-48 
But we're also given perimeter = 172'
Therefore 4L-48=172
solve for L
4L=172+48=220
L=55'
W=55-24 =  31'
Check: Perimeter = 2(W+L)=2(31+55)=2*86=172'  good!

Answer: The dimensions of the garden are 31' * 55'

Ierofanga [76]

Answer: 30%


Step-by-step explanation:

The first step is to find the increase in numbers

26-20= 6

Now you find the percent. This means you're looking for the percent 6 is equal to when compared to 20. The easiest way is to divide the increase by the original number

6/20= 0.3

To convert that to percent, multiply it by 100

0.3 * 100= 30%

There was a 30% increase.

You join an Internet service. You get the first 5 hours for free, and then you pay $2 per hour. How many hours of Internet use,
Vika [28.1K]

Answer:

27

Step-by-step explanation:

firstly we know we get 5 hour free so we know that when we add our total it will go up by 5. an easy way to do the equation is to take 45 and divide by two because we are essentially paying two of our 45 dollars every hour. this means that we will get half the amount we pay in hours. 45/2 =22.5 (do not round up because you will only get what you pay for and if you cant pay for a full hour you just do not get it) 22+5=27. so you get 27 hours of internet.
