If Noah is running 6 miles an hour then we know that for every hour, he is running 6 miles. You have to multiply each hour he’s running by 6.

For the last three answers, since they give you how much time he ran, you have to divide by 6 miles.

Answers:
1 = 6
1/2 = 3
1 1/3 = 8
(I can’t see the fourth one)
1 1/2 = 9
3/4 = 4 1/2

for a short time after a wave is created by wind the height of the wave can be modeled using y= a sin 2pit/T where a is the ampl
dangina [55]

Answer:

y = 4 sin(t/2 + 4π/3) − 2

Step-by-step explanation:

General form:

y = a sin(2π/T t)

Given a = 4 and T = 4π:

y = 4 sin(2π/(4π) t)

y = 4 sin(t/2)

Add horizontal shift of -4π/3 and vertical shift of -2:

y = 4 sin(t/2 − (-4π/3)) − 2

y = 4 sin(t/2 + 4π/3) − 2

A 10 2/3 inch long pipe is cut into 8 equal length pieces, how long is each piece​
storchak [24]

Answer:

\frac{4}{3} inches

Step-by-step explanation:

The total length of pipe is  10  2/3rd inches

It is cut into 8 equal pieces

We need to divide total length by 8 to get length of each piece. First, we have to convert mixed number (total length) to improper fraction by using formula shown below:

a\frac{b}{c}=\frac{(a*c)+b}{c}

So,

10\frac{2}{3}=\frac{32}{3}

Each piece length is:

\frac{\frac{32}{3}}{8}\\=\frac{32}{3}*\frac{1}{8}\\=\frac{32}{24}\\=\frac{4}{3}

So, each piece is \frac{4}{3} inches

Due to conservation efforts, the gray whale has been removed from the endangered species list. There are now 13,000 in the world
brilliants [131]

Answer:

P = 13,000(1.11) ^ t

Step-by-step explanation:

This scenario can be modeled using an exponential growth equation.

The exponential growth equations have the following form:

P = p (1 + r) ^ t

Where P is the population in year t

p is the initial population at t = 0

r is the growth rate

t is the time in years.

In this case we know that the current population is 13,000 and that the growth rate is 11%

So

p = 13,000\\r = 0.11

The equation that models this scenario is:

P = 13,000(1 + 0.11) ^ t

P = 13,000(1.11) ^ t
