It would equal 5 x 10 ^ 10
because 10 ^ 10 is 10 billion and 9 x 10 billion is 90 billion and 4 x 10 billion is 40 billion. so, 90 billion - 40 billion. that's 50 billion, and that can be turned into 5 x 10 ^ 10.
Answer: 9
Step-by-step explanation:
Answer:
Perpendicular
Step-by-step explanation:
m=y2-y1/x2-x1
m=15-3/14-(-2)
m=3/4
7^(7n + 7) = 2401
apply log on both sides to solve the equation
log 7^(7n + 7) = log 2401
the power is brought forward
(7n + 7) log 7 = log 2401
7n +7 = log 2401 / log 7
7n + 7 = 4
7n = -3
n = -3/7
Hope it helped!
First we need to have same units before comparing them. That is, either both of them are in cm or both of them are in mm. So if we need to convert 12.5 cm to mm, we know that 1 cm =10 mm. So we have to find out how many mm are in 12.5 cm. And let 12.5 cm =x mm. So to find the value of x , we set a proportion and solve for x. That is

The units cancel out and we do cross multiplication. That is

x=125
So 12.5 cm =125 mm. Therefore the correct proportion is C.
