8^-3 is the answer.. when two numbers of the same base in a fraction form are stacked on top of each other, the exponents always SUBTRACT.. so 3-6 is -3 and the base stays the same :)

Multiplying and Dividing by Powers of 10 When multiplying a number by 10, move the decimal to the right. When multiplying a numb

Answer:

Because we actually divide by 10 when a number is multiplied by 0.1.

Step-by-step explanation:

Let $a$ be a number.

When we multiply a number by 10:

$a \times 10 = 10 a$ (One '0' is increased in the number)

For example:

$23 \times 10 = 230$

Considering a decimal number:

$2.3 \times 10 = 23$

Multiplying a number with 0.1 (which is actually $\frac{1}{10}$ ) means dividing the number by 10.

$23\times 0.1 =23\times \frac{1}{10}=2.3$

Considering a decimal number:

$2.3 \times 0.1 = 2.3 \times \frac{1}{10} = 0.23$

Therefore, When multiplying a number by 0.1, move the decimal to the left.

Find m angle A

stepan [7]

Answer:

D. 14°

Step-by-step explanation:

The Law of Sines tells you sides are in proportion to the sine of the opposite angle:

sin(A)/BC = sin(B)/AC

sin(A) = BC/AC·sin(B)

A = arcsin(BC/AC·sin(B)) = arcsin(7/28·sin(75°)) ≈ 13.974° ≈ 14°
