Answer:

option-C

Step-by-step explanation:

We are given

At 9:00 a.m., a wind speed of 20 miles per hour was recorded

So, initial wind speed =20 miles per hour

Each measurement showed an increase in wind speed of 3 miles per hour

The strongest wind was recorded at 4:00 p.m

so,

top wind speed = initial wind speed + ( total number of hours between 9:00 am and  4:00 pm)*(change in wind speed)

top wind speed = 20 mph+(16-9)*3

=20+7\times 3

=41 miles per hour

Since, change in wind speed and initial wind speed are constant

but the number of hours it took for the wind speed to reach its minimum for the day can be changed

so, most important variables is

the number of hours it took for the wind speed to reach its minimum for the day can be changed

Calculate 936 divided by 36 show your working out
Tema [17]
To do this without a calculator, the best method would be chunking.

Minus 36 from 936 in groups of ten until a smaller number is reached; record the number in each group.

936 - (10 x 36)
936 - 360 = 576

576 - (10 x 36)
576 - 360 = 216

216 - (5 x 36)
216 - 180 = 36

36 - (1 x 36)
36 - 36 = 0

Add up all the bold numbers

10 + 10 + 5 + 1 = 26

Find the unit rate with the numbers 12 and one and one half
kati45 [8]

Answer:

The value of the unit rate is 8

Step-by-step explanation:

we know that

To calculate the unit rate simply divide the first number by the second number

so

12:1\frac{1}{2}

Convert mixed number to an improper fraction

1\frac{1}{2}=1+\frac{1}{2}=\frac{1*2+1}{2}=\frac{3}{2}

substitute in the expression above

12:\frac{3}{2}=\frac{24}{3}=8
