Answer:

Step-by-step explanation:

By the Pythagorean Theorem we know that the hypotenuse squared is equal to the sum of its squared sides.

h^2=x^2+y^2

Here y=25 and x=8 so

h^2=25^2+8^2

h^2=625+64

h^2=689

h=26.25 ft

They obviously rounded to nearest whole foot.

So Carrie is correct in saying the ladder should be 26 feet.

Archy [21]
5 feet = 60 inches
4 1/2 inches = 1 hour
60 inches = 1 ÷ 4 1/2 x 60
= 13 1/3 hours

If the snow keeps accumulating, it would take 13 1/3 hours for 5 feet of snow to accumulate.

Lily invested $750 in a savings account and earned $225 in interest at the end of 5 years.
slava [35]
After 5 years Lily has $750+$225 = $975
The equation for interest rate looks like:
750 * x^5 = 975 
x^5 = 975/750
x^5 = 1.3
x = \sqrt[5]{1.3}
x = 1,0538
That means that interest rate is approximately 5,5% (B)

The reason for this calculation is because each year you multiply your money with interest rate and add that to your starting money.
After one year you will earn
750 + 750 * interest rate = money after 1 year.
After 5 years we multiply 5 times so our interest rate is x^5 and money after 5 years is 750 + 225.
