What expression is not equivalent to 1/343

Mathematics
1 answer:
GREYUIT [131]3 years ago
7 0
1 / 343
This is just equal to 
1 / 7^3 = 7^-3

A. 7^-1 * 7^-2 = 7^(-1 + -2) = 7^-3
B. 7^7 * 7^-10 = 7^( 7+ -10) = 7^-3
C. 7^-2 * 7^-5 = 7^(-2 + -5) = 7^-7
D. 7^-5 * 7^2 = 7^(-5 + 2) = 7^-3

So the correct answer is letter C. 7^-2 * 7^-5

Can somebody please help me with this question??:,,)
MatroZZZ [7]

Answer:

30 and 60

Step-by-step explanation:

1. "The measure of angle is twice the measure of its complement" means that one angle is twice the amount of another angle, and when both of them are added together, they equal 90°.

2. 60 is twice the amount of 30, and when both of them are combined, they equal 90°.

Therefore, the answer is 30 and 60.
