1/2 of an hour is = 30
288 / 4.30=67
The answer is 67 miles per hour.
Answer:
D) 32.5 ft
Step-by-step explanation:
Here we have to use the trigonometric ratio.
We need to find the length of the hypotenuse.
We use sin ratio.
Sin 38 = Opposite / Hypotenuse
Here opposite = 20, Hypotenuse = Length of the six cars
sin 38 = 20 / length of the six cars
The length of six cars = 20 / sin 38
The length of the six cars = 32.48
Which is closest to 32.5 ft
Thank you.

Answer:
68%
Step-by-step explanation:
Divide the amount she spent this year, by the amount she spent last year, in this case, 393 divided by 572 =0.68706293706, but we need to make it into hundredths, so it is 0.68, or 68%.
<span>The equation that can be used is 90-10y=5x. In order to get this answer, you first start with figuring out how many miles total were hiked for each trail. The 5-mile mountain trail total would be equal to 5x and the 10-mile canal trail total would be 10y. Adding both of these totals together would give you 90 miles and an equation of 5x+10y=90. All you do now is rearrange the equation by subtracting 10y from each side and you get 90-10y=5x.</span>
