A local concert promoter purchases 2 3/4 pages of ads. When one of the concerts is cancelled, the promoter cancels 1 5/8 pages o

Lynna [10]

Answer:

1 $\frac{1}{8}$ pages

Step-by-step explanation:

Since the concert promoter started with 2 $\frac{3}{4}$ pages of ads but had to cancel 1 $\frac{5}{8}$ , subtracting the cancelled amount from the original amount will give the amount of advertising space the promoter is now actually using:

2 $\frac{3}{4}$ = 2 $\frac{6}{8}$

- <u>1 $\frac{5}{8}$ </u> - <u>1 $\frac{5}{8}$ </u>

1 $\frac{1}{8}$ pages

In order to subtract fractions, you need to have like denominators, so you need to convert $\frac{3}{4}$ into an equivalent fraction with a denominator of '8'. Since 4 x 2 = 8, then you also need to multiply the numerator by the same factor: 3 x 2 = 6.

What expression is equal to COS B????

Murrr4er [49]

Answer:

A/C

Step-by-step explanation:

Since the sum of the angles in a triangle equals 180°, and angle C is 90°.

That means angles A and B add up to 90°, that is, they are complementary angles. Therefore the cosine of B equals the sine of A.

We saw on the last page that sin A was the opposite side over the hypotenuse, that is, a/c. Hence, cos B equals a/c.

Your welcome! :)
