Answer:

The overall change in temperature over the time period ∆T = -12.6°F

Step-by-step explanation:

Rate of change of temperature r = -2.8°F per hour

Time t = 4.5 hours

The overall change in temperature ∆T = Rate of change of temperature × time period

∆T = r × t

∆T = -2.8°F per hour × 4.5 hours

∆T = -12.6°F

The overall change in temperature over the time period is -12.6°F

13 Solve the inequality n+7&lt;5n-8<br>​
Papessa [141]

Answer:

3.75 < n

Step-by-step explanation:

n + 7 < 5n - 8

Add 8 to both sides

n + 7 + 8 < 5n

n  + 15 < 5n

Subtract 'n' from both sides

15 < 5n - n

15 < 4n

Divide both sides by 4

\frac{15}{4} < n

3.75 < n

John di Silvestre obtained a loan to buy a cello for $8,400. He pays 12% exact interest on the loan for 146 days. What is the am
Svetradugi [14.3K]
<span>Normally when they tell you interest rate they say per annum meaning the percent interest rate for a year.

But in this problem they seem to say John pays 12% for a 146 day loan.

So interest = P * r / 100 = 8400 * 12/100 = $1,008.00
Maturity value = Principal + Interest = 8400 + 1008 = $9,408.00</span>

How many total ounces of chicken
aleksklad [387]

Answer:

An average chicken breast weighs 174 g, or about 6 ounces (oz). But sizes vary from smaller cuts at around 4 oz, to larger ones at 8 to 10 oz. There's no right or wrong choice here. It really depends on what you're cooking and how much chicken you want.
