Answer:

y = 2x

As you can see 2 times x would equal to y in this situation so the constant of variation would be y=2x

Hope it is right and helped :3

SOMEONE PLEASE HELP!

Andrews [41]

Answer:

17.2°

Explanations

To find angle A, use the cosine rule.

a^2 = b^2 + c^2 - 2 × a × c cos A

4^2 = 7^2 + 10^2 - 2 × 7 × 10 cos A

16 = 49+ 100 - 140 × cosA

16 = 149 - 140cosA

16- 149 = - 140cosA

-133 = - 140cosA

cosA = 133/140

cosA = 0.95

A = 17.2°

Solve. Use models to help you.

Answer:

3.38

Step-by-step explanation:

x + y + z = 16.9

x = 2y

y = z

y=y

2y (x) + y(y) + y(z) = 16.0

5y = 16.9

y = 3.38

A sailboat traveled 30 miles in 2.5 hours. At the same speed, how far can the boat sail in another 4.5 hours ?

Ivanshal [37]

54 miles

using the formula

speed = $\frac{distance}{time}$ = $\frac{30}{2.5}$ = 12 mph

continuing at 12 mph then

distance = speed × time = 12 × 4.5 = 54 miles
