$7.40/8 = $0.925 per pound.
$5.38/4 = $1.345 per pound.
1.345 > 0.925, so it's better to buy the 8 pound bag rather than the 4 pound bag.

The formula for wind chill (in degrees Fahrenheit) is given byC = 35.74 + 0.6215T ? 35.75v0.16 + 0.4275Tv0.16 where is the wind

PIT_PIT [208]

Answer:

dC =0.6899T + 30.02

dC/C = (0.6899T + 30.02)/(35.74 + 0.6215T - 35.75V^0.16 + 0.4275Tv^0.16

Step-by-step explanation:

C= 35.74 + 0.6215T - 35.75v^0.16 + 0.4275Tv^0.16

dC = 35.74 + 0.6215T - (35.75×0.16) +:(0.4275×0.16)

dC = 35.74 + 0.6215T - 5.72 + 0.684T

dC = 0.6899T + 30.02

dC/C = (0.6899 + 30.02)/(35.74 + 0.6215T - 35.75Tv^0.16 + 0.4275Tv^0.16

Nicole left home and traveled toward the recycling plant. Two hours later Kristin left traveling at 50 km/h in an effort to catc

Sedaia [141]

Answer:

Nicole's average speed is $30\ km/h$ .

Step-by-step explanation:

Given,

Speed of Kristen = $50\ km/h$

Time taken by Kristen to cover the distance = $3\ h$

Solution,

We can find out the distance traveled by Kristen by multiplying speed with time.

$Distance = Speed\times Time$

$Distance =50\ km/h\times 3\ h=150\ km$

The distance traveled by Kristen is equal to distance traveled by Nicole.

As the question said Kristen left 2 hours later and cover the distance in 3 hours.

That means Nicole take 5 hours to cover the distance.

So, For Nicole;

Distance = 150 km

Time = 5 hrs

Here we use the formula of speed.

$Speed = \frac{Distance}{time}$

Now substituting the values, we get;

$Speed = \frac{150\ km}{5\ h}=30\ km/h$

Hence Nicole's average speed is $30\ km/h$ .

The RANGE of the function f is

monitta

Answer:

Step-by-step explanation:

The range of the function is what values of y from lowest to highest that are covered by the function. The domain are the values on the left: A-E; the range are the values on the right: 1-3. We state both domain and range in interval notation, stating only the lowest and highest values in either a set of brackets if the values are included, a set of parenthesis if the values are not included, or a mixture of both. Our range is inclusive, so we mention the lowest and the highest only: [1, 3].

Which number line best shows the position of square root of 7?

Serggg [28]

Step-by-step explanation:

First off, you want to find the whole number in square root form

1 = √1

2 = √4

3 = √9

4 = √16

5 = √25

You want to find which to numbers √7 is in between

7 is between 4 and 9 so the √7 is in between √4 and √9 which means that √7 is between 2 and 3

The second one is your answer

I hope this helps!!!
