Answer: BC = 41

Step-by-step explanation:

AB + BC = AC

8x + 9 + 6x + 5 = 98

14x + 14 = 98

14x = 84

x = 6

BC = 6x + 5

Substitute 6 for x

BC = 6 (6) + 5

BC = 36 + 5 = 41

Hope it helps!

Answer:

BC = 41 degrees

Step-by-step explanation:

You know that AB + BC = AC, so:

8x + 9 + 6x + 5 = 98

14x + 14 = 98

14x = 84

x = 6

BC = 6x + 5

substitute in x = 6:

BC = 6 * 6 + 5

= 36 + 5

= 41

james borrows Php 700000 and promises to pay the principal and interest at 15% compounded monthly. How much must he repay after
Licemer1 [7]

Answer:

A = $ 1,987,379.10 + 700,000= $2,687,379.10

Step-by-step explanation:

15% = 0.15 rate per tear

A = P (1+r/n)^nt

A = 700,000 (1+0.015/12)^12*7

A = 700,000 (1+0.0125)^84

A = 700,000 ((0.9875)^84

A = 700,000 (2.839113)

First, you need to find the height, in which it says “a height that’s half the length of the longer base side. Can you guess what that is between 7 and 5? It is 7. And you would find half of that which is 3.5. Now you know the height is 3.5. The formula to find a rectangular pyramid's volume is lwh/3 which you would do 7 * 5 * 3.5, which is equal to 122.5, and then you would divide that by 3, which is 40.833 which would round to 40.8, so there is your answer.
It is 40.8 units^3
