If the total amount of people serving as of January is estimated to be 1,400,000 people, how many are in the Air Force?
d1i1m1o1n [39]

Answer:

<em>There are 364,000 people in the Air Force.</em>

Step-by-step explanation:

<u>Percentages</u>

The N% of a number M is calculated by:

\displaystyle \frac{N*M}{100}

For example, 15% of 280 is

\displaystyle \frac{15*280}{100}=42

We know the total amount of people serving as of January is estimated to be 1,400,000 people and that 26% of them are serving in the Air Force.

Compute 26% of 1,400,000:

\displaystyle \frac{26*1,400,000}{100}=364,000

There are 364,000 people in the Air Force.

Answer:

y = -\frac{1}{3}x + 3

Step-by-step explanation:

2 = −⅓[3] + b

−1

3 = b \\ \\ y = -\frac{1}{3}x + 3

Perpendicular Lines have OPPOSITE MULTIPLICATIVE INVERSE <em>RATE OF</em><em> </em><em>CHANGES</em><em> </em>[<em>SLOPES</em>], so 3 becomes −⅓.
