What is 15% of 450 show your work

Answers

Easy, change 15% into 0.15

n=0.15*450

n=67.5

Thus, your answer is, 67.5
15 becomes 0.15 after you divide 15 by 100
Next, do 0.15 times 450 which equals
 67.5
rounded, this would become 68
So, the answer is 67.5

A cheetah’s speed was timed over a 100- yard distance. The cheetah was clocked running 70 miles per hour. Which equation shows the relationship between the distance, y, and time, x, the cheetah runs?A y=100x C y=100x+70
B y=70x+100 D y=70x

Answers

Speed is the rate of change of distance over time.

The equation that shows the relationship is y = 70x

The given parameters are:

Distance = 100 yards

Speed = 70 miles per hour

Speed is calculated as:

Speed = Distance / Time

So, we have:

70 = y/x

Multiply both sides by x

y = 70x

Hence, the equation that shows the relationship is y = 70x

Answer with Step-by-step explanation:

The cheetah was clocked running 70 miles per hour.

i.e. in 1 hour cheetah covered 70 miles

in 2 hours cheetah covered 140 miles

in 3 hours cheetah covered 210 miles

in general, in n hour cheetah covered 70n miles

If y denote the distance covered

and x denotes the time cheetah runs

Then, y=70x

Hence, the equation which shows the relationship between the distance, y, and time, x, the cheetah runs is:

D  y=70x
