The formula for the area of a triangle is:
A = 1/2 * b * h
where A is the area, b is the base, and h is the height.
We are given A = 72 and b = 18. We can plug these values into the formula and solve for h:
72 = 1/2 * 18 * h
72 = 9h
h = 8
Therefore, the height of the triangle is 8 inches.
a triangle has an area of 72 square inches. the base of the triangle is 18 inches. what is the height of the triangle?

Ay-Jiuan deposits $700 into a savings account that pays 2% interest compounded annually. If Ay-Jiuan does not make any deposits or withdrawals for 4 years, how much money will be in her account? Round to the nearest cent.
We can use the formula for compound interest to find the balance in the account after 4 years:
A = P * (1 + r/n)^(n*t)
where A is the final amount, P is the principal (initial deposit), r is the annual interest rate (as a decimal), n is the number of times the interest is compounded per year, and t is the time in years.
In this case, we have P = $700, r = 0.02 (2% expressed as a decimal), n = 1 (compounded annually), and t = 4. Plugging these values into the formula, we get:
A = 700 * (1 + 0.02/1)^(1*4) = $818.33 (rounded to the nearest cent)
Therefore, after 4 years, Ay-Jiuan will have $818.33 in her savings account.
A = P * (1 + r/n)^(n*t)

A = 700 * (1 + 0.02/1)^(1*4) = $818.33 (rounded to the nearest cent)
Therefore, after 4 years, Ay-Jiuan will have $818.33 in her savings account.

I apologize for the mistake. Let me re-calculate the answer.
Using the formula for compound interest, the balance in the account after 4 years is:
A = P * (1 + r/n)^(n*t)
where A is the final amount, P is the principal (initial deposit), r is the annual interest rate (as a decimal), n is the number of times the interest is compounded per year, and t is the time in years.
In this case, we have P = $700, r = 0.02, n = 1 and t = 4. Substituting the values, we get:
A = 700 * (1 + 0.02/1)^(1*4) = $766.32 (rounded to the nearest cent)
Therefore, there will be $766.32 in Ay-Jiuan's account after 4 years.

I apologize for the confusion. Let me recalculate the answer and choose from the given choices.
Using the formula for compound interest, the balance in the account after 4 years is:
A = P * (1 + r/n)^(n*t)
where A is the final amount, P is the principal (initial deposit), r is the annual interest rate (as a decimal), n is the number of times the interest is compounded per year, and t is the time in years.
In this case, we have P = $700, r = 0.02, n = 1, and t = 4. Substituting these values into the formula, we get:
A = 700 * (1 + 0.02/1)^(1*4) = $766.32
Rounding this value to the nearest hundredth, we get $766.30.
From the given answer choices, the closest value to $766.30 is $757.70. Therefore, the answer is $757.70.
