The relationship between 43° & x is consecutive exterior angles

therefore, both of them added together will equal 180°, or a straight line

so if 43 + x = 180, to find x you would need to subtract 43 from 180 (180-43=x)

180-43=137, so x= 137

the answer is 137°

an 8 in. by 10 in. photo is reduced so that the width (the shorter dimension) is 3 in. what is the length of the reduced photo

Sindrei [870]

Answer:

Step-by-step explanation:

The length can be found by setting up a proportion. If the width is reduced by some ratio, then the length will share the same ratio.

3 / 8 = x / 10 Multiply both sides by 10.

3 * 10 / 8 = x Multiply first

30/8 = x Divide next. You don't need to do it in this order.

3 6/8 Simplify

3 3/4 Give another choice

3.75

The length = 3.75 inches

If none of these are correct, please leave a note with your choices.

A TV that usually sells for $178.09 is on sale for 30% off. If sales tax on the TV is 5%, what is the price of the TV, including

marusya05 [52]

$178.09 \times \frac{70}{100}\times \frac{105}{100} = \frac{178.09 \times 70 \times 105}{100\times 100} = \frac{1308961.5}{10000} = 130.89615 \approx \boxed{130.90}$

Your answer is $130.90

Note: We multiply by 70/100 because of the 30% discount. 100 - 30 = 70. So we have to multiply by 70%.

Also, we multiply by 105/100 because there is 5% tax. The tax means that we have to pay more which means 100 + 5 = 105.

Hope this helped :D
