Answer:
= 18 cm^3
Step-by-step explanation:
V = Bh where B is the area of the base, which is the triangular face
B = 1/2 (4*3) = 6
V = 6* 3
V = 18 cm^3
Answer:
a
Step-by-step explanation:
Answer:
a) 1/10, 7/24, 1/2, 13/20
8 + 6 + 9 + 12 + 4x / 5 = x Original Problem.
25 + 4x / 5 = x Addition.
25 + 4x = 5x Multiply each side by 5.
25 = x Subtract 4x from each side.
x = 25 Switch equation around.
Answer: x = 25
Recall that to compute for the new amount of the original sum at a compound interest is
A(t) = P(1 + r/n)^(nt)
where P is the original amount, r is the interest rate, n is the number of times P is compounded each year, and t is the number of year.
With this, the total amount owed by Sam in five full years becomes [(120)(1 + 0.30/12)^60 ]. The total interest is the difference between the original amount owed and the amount that needs to be paid over time. Thus, total interest is [(120)(1 + 0.30/12)^60 ] - 120 = 407.97.
Therefore, the total interest is $407.97<span>.</span>
