A cyclist travels 56 miles in 4 hours. What is the cyclist speed in feet per second
Step2247 [10]

Answer:

21.09 ft/s

Step-by-step explanation:

The first step is to create the ratio of speed/time.

\frac{56 miles}{4 hours}

Next we must simplify

\frac{14 miles}{1 hour}

Next we must convert 14 miles in to feet. There are 5280 feet in a mile.

14 * 5280ft = <u>75,920 feet</u>

Now for hours into seconds.

1 hour = 60 min, 60 min = 3600 seconds

Our new ratio is \frac{75920ft}{3600sec}

simplify.

75920ft / 3600sec = 21.09ft/s

Trip bought an ice cream cone that is 4 inches tall with a radius of 2 inches the cone has a mass of about 3 ounces when empty a
SVEN [57.7K]
We know that
[volume of the cone]=(1/3)*pi*r²*h
for r=2 in
h=4 in
[volume of the cone]=(1/3)*pi*2²*4-----> 16.747 in³

volume of the hemisphere=(4/6)*pi*r³
for r=2 in
volume of the hemisphere=(4/6)*pi*2³----> 16.747 in³

[<span>the density of the ice cream]=mass ice cream/volume ice cream
</span>
mass ice cream=35 oz-3 oz-----> 32 oz

volume ice cream=volume of a cone +volume of hemisphere
volume ice cream=16.747+16.747----> 33.494 in³

density ice cream=32/33.494-----> 0.955 ounces/in³

the answer is
0.955 ounces/in³
