Using the average rate of change, it is found that the average rate is of:

(1) 2.1 °F per minute

<h3>What is the average rate of change of a function?</h3>

It is given by the <u>change in the output divided by the change in the input</u>.

In this problem:

At 15 minutes, the temperature was of 90ºF.

At 45 minutes, the temperature was fo 153ºF.

Hence, in 30 minutes, the temperature increased 63ºF, hence the rate is given by:

r = 63/30 = 2.1 °F per minute.

A student charges $31.50 for 3 hours of babysitting. If the amount the student earns babysitting is proportional to the hours sp

vodomira [7]

Answer:

C) y is equal to 10.5x

Step-by-step explanation:

$31.50 is charged for <em>3 </em>hours so, for 1 hour we need to divide 31.50 by 3, which results in 10.50. So 1 hour of babysitting is $10.50

this is because x is equal to the number of hours they babysit. we do not know the actual so it is replaced with x

and y is equal to the sum of 10.5x because we multiply the number of hours worked, and the amount per hour.

5,25,125 find 10th term

anastassius [24]

Answer:

9765625

Step-by-step explanation:

There is a common ratio between consecutive terms , that is

r = 25 ÷ 5 = 125 ÷ 25 = 5

This indicates the sequence is geometric with n th term

$a_{n}$ = a₁ $r^{n-1}$

where a₁ is the first term and r the common ratio

Here a₁ = 5 and r = 5 , then

a₁₀ = 5 × $5^{9}$ = 5 × 1953125 = 9765625

Camellia earned $160 over the summer. If you put 80% of earnings into her savings account and spent 75% of the rest on a gift fo

In-s [12.5K]

Answer: She has left over $8.

Step-by-step explanation:

Hi, to answer this question we have to analyze the information given:

<em>Camellia earned $160 and you put 80% of earnings into her savings account: </em>

So, to obtain this number we have to multiply Camellia's earnings by 0.80 (the percentage in decimal form, 80 /100 = 0.80)

$160 x 0.80 = $128 (savings)

If we subtract the number obtained to Camellia's earnings:

$160 -$128 = $32 (money left without purchasing a gift)

<em>She spent 75% of the rest on a gift for her </em>

The rest is $32, so we have to multiply it by the percentage in decimal form (75/100=0.75)

$32 x 0.75 (decimal form) = $24

And finally, subtract that number to the original rest.

$32-$24 = $8

She has left over $8.
