Answer:
Part A: option C. 135.2°F
Part B: 40 min
Step-by-step explanation:
<em>Part A:</em><em> What is the temperature in degrees Fahrenheit of the soup after 25 minutes?</em>
<u>1. Set an equation</u>:
- Temperature = Initial temperature - decrease in temperature
- decrease in temperature = rate of decrease × time
- Variables:
temperature: T
initial temperature: To = 192.7°F
decrease rate: 2.3°F / min
time = t
- Equation: T = 192.7°F - 2.3(°F/min) × t
2.<u> Substitute t = 25 min</u>
- T = 192.7°F - 2.3 (°F/min) × 25 min = 135.2 °F
Part B. <em>How many minutes will it take for the soup to cool to 100.7°F?</em>
2.<u> Solve the equation for t</u>
- T = 192.7°F - 2.3(°F/min) × t ⇒ t = (192.7 °F - T) / (2.3 °F/min)
3. <u>Substitute T = 100.7°F</u>
- t = (192.7°F - 100.7°F) / (2.3 °F/min) = 40 min
Part A.
7.8 is a rational number between 7.7 and 7.9.
It is rational because it can be written as a fraction of integers, such as 78/10.
Part B.
sqrt(60) = 7.75
sqrt(60) cannot be written as a fraction of integers. It is a decimal number that never ends and never repeats.
Answer:
$151,257.12
Step-by-step explanation:
7.5% is the annual interest rate, the monthly interest rate is:

The amount (P) that must be deposited into an account at a rate 0.625% per month for 7 months in order to obtain $158,000 is given by:

$151,257.12 must be deposited into the account today.
Given:
The point is T(-3,7).
To find:
The image T' after
.
Solution:
, it means reflection across x-axis is followed by reflection across y-axis.
If a point is reflected across the x-axis, then


Then point is reflected across the y-axis. So,


Therefore, the coordinates of point T' are (3,-7).
Answer:
Explanation:
Please, see attached the chart corresponding to this question.
The<em> chart</em> is a pie chart that shows the percentage composition of the <em>expenses </em>and uses color to identify each item.
The items corresponding to<em> taxes</em> are:
- <em>Federal tax: 29%</em>
- <em>State tax: 6%</em>
All the other expenses are not taxes.
Add the two items that are taxes: 29% + 6% = 35%.
Hence, the expenses that are not taxes can be calculated by difference:
