Ok, first let's find how much a nickle is worth, a nickle is worth $0.05.

0.05 x 27 = $1.35

0.05 x 32 = $1.60

0.05 x 39 = $1.95

0.05 x 47 ≠ $2.45 (It's equal to $2.35)

I hope this helps!

What is the measure of z?
Lady bird [3.3K]

Answer:

The missing angle is 24 degrees

Step-by-step explanation:

The two angles form a straight line so they add to 180 degrees

x+156 = 180

Subtract 156 from each side

x+156-156 = 180- 156

x = 24

The missing angle is 24 degrees

What is the value of y in the triangle
Scrat [10]

Answer:

y ≈ 6.7

Step-by-step explanation:

Using the sine ratio in the right triangle

sin26.5° = \frac{opposite}{hypotenuse} = \frac{y}{15} ( multiply both sides by 15 )

15 × sin26.5° = y , then

y ≈ 6.7 ( to 1 dec. place )
