Steve puts an 18-foot ladder against his house. The ladder reaches a height of 15 feet on the house. How far is the bottom of th
krek1111 [17]

Answer:

3 \sqrt{11}

Step-by-step explanation:

Since we are given the hypotenuse which is 18 since it slanted, and leans on the house. And we are given one of the legs which is 15 since it is vertical. We can use the pythagorean theorem to solve for this problem.

{a}^{2}  +  {b}^{2}  = c {}^{2}

where a and b are the legs and c is the hypotenuse l.

Let plug it in

{a}^{2}  + 15 {}^{2}  =  {18}^{2}

{a }^{2}  + 225 = 324

{a}^{2}  = 99

a =  \sqrt{99}

a =  \sqrt{9 \times 11}

a = 3 \sqrt{11}

vichka [17]

Answer: 192.75

Step-by-step explanation:

I am answering your question assuming that the three amounts were checks that were written out during the week.

Beginning balance = 345.28

Subtract the total amount of the checks (65.08 + 24.50 + 118.95 = 208.53)

345.28 - 208.53 = 136.75

Next, add the amount of the deposit. 136.75 + 56.00 = 192.75
