Answer:

41 inches of wire will cost 164 cents.

Step-by-step explanation:

1st Method

Use proportions!

18/ 72 = 41/ c

Cross multiply

18 * c = 72 * 41

18c = 2952 divide both sides by 18

c = 164

2nd Method.

Find the rate of the costs. r = rate

18*r = 72

r = 4 cents/inch

Now that you've found the rate you can multiply it by 41 inches to find the cents the wire costs!

41 inch * r (cents/inch) inches cancels out.

41 * 4 = 164

164 cents

One angle of a triangle measures 65°. The other two angles are in a ratio of 3:20. What are the measures of those two angles?

Nataly_w [17]

Answer:

15° and 100°

Step-by-step explanation:

$65 + 3x + 20x = 180$

$23x = 115$

$x = 5$

3 × 5 = 15, 20 × 5 = 100. So the other two angles measure 15° and 100°.
