Answer:
The length would be 30 and the width would be 20
Step-by-step explanation:
For the purpose of this, we'll set the width as x. We can then define the length as x + 10 since we know it is 10 ft longer than the width. Now we can use those along with the perimeter formula to solve for the width.
P = 2l + 2w
100 = 2(x + 10) + 2(x)
100 = 2x + 20 + 2x
100 = 4x + 20
80 = 4x
20 = x
Now since we know that the width is 20ft, we can add 10ft to it to get the length, which would be 30ft.
Answer:
The price of the cupcakes
Step-by-step explanation:
The expression represents the price of the cupcakes. D represents the dollar amount. If you were to do d-7 then you would get the price of the cake but since it's d+7 it would be the cupcakes
12.5%
First you need to find how much more the population increased (700 people)
Then you set up for a cross multiply and divide
700/5600 x/100
the 700 OVER 5600 people in fraction format shows the number of people arrived against the number of people already present
the x OVER 100 are the percentages, x representing what we need to find
The next step would then multiply 700x100 (cross multiply)
Then with the number you found 70,000 you would then divide by 5600 (divide)

Answer:
=4sqrt(10)
Step-by-step explanation:
The geometric mean of two numbers is sqrt(a*b) where a and b are the two numbers
geometric mean = sqrt(8*20)
=sqrt(160)
= sqrt(16*10)
We know that sqrt(ab) = sqrt(a) sqrt(b)
=sqrt(16) sqrt(10)
=4sqrt(10)
