Numbers like 10, 100, 1,000, and so on are called?

1 answer:

3 0

Numbers starting with a 1 and followed by only 0s (such 10, 100, 1,000,10,000, and so forth) are called powers of ten, and they're easy to represent as "exponents". Powers of ten are the result of multiplying 10 times itself any number of times.

2. Solve the following 10/12 - 4/3

Mama L [17]

The answer is $-\frac{1}{2}$

First you must change the fractions so that they have like denominators.

$\frac{10}{12} -\frac{16}{12}$

Then you subtract the fractions.

$-\frac{6}{12}$

Finally, you need to simplify the answer.

$-\frac{1}{2}$

Find the measure of the indicated angle below

Norma-Jean [14]

Answer:

The measure of x is $70\°$

Step-by-step explanation:

we know that

The formula to calculate the sum of the internal angles of a polygon is equal to

$S=(n-2)*180\°$

where

n is the number of sides

In this problem we have

$n=9\ sides$

substitute

$S=(9-2)*180\°=1,260\°$

Find the measure of each internal angle

Divide the sum of the internal angles by the number of sides

$1,260\°/9=140\°$

The value of x is half the measure of internal angle

$x=140\°/2=70\°$
