We can conclude the following information:

Every 3 hours the temperature changes.

<em>At 9 AM, the temperature </em><em><u>was -1.6°F</u></em><em>:</em>

9 AM = -1.6°F =>

<em>Between 9 AM and noon, the temperature </em><em><u>rose 6.6°F</u></em><em>:</em>

12 PM = -1.6 + 6.6 = 5°F =>

<em>Between noon and 3 PM, the temperature </em><em><u>increased by 2.8°F</u></em><em>:</em>

3 PM = 5 + 2.8 = 7.8°F =>

<em>Between 3 PM and 6 PM, the temperature </em><em><u>went down 10.5°F</u></em><em>:</em>

6 PM = 7.8 - 10.5 = -2.7°F

<em>What was the </em><em><u>temperature at 6 PM</u></em><em>? </em>

-2.7°F

Marcus sails due north and Sandra sails due east from the
garri49 [273]

Answer: The boats are 44.82 miles from each other.

Step-by-step explanation:

The direction of movement of Marcus and Sandra forms a right angle triangle.

The distance sailed by Marcus due North would represent the opposite side of the right angle triangle.

The distance sailed by Sandra due east would represent the adjacent side of the right angle triangle.

The distance, h between the both of them after 2 hours represents the hypotenuse of the right angle triangle.

To determine h, we would apply Pythagoras theorem which is expressed as

Hypotenuse² = opposite side² + adjacent side²

h² = 35² + 28² = 1225 + 784

h² = 2009

h = √2009

h = 44.82 miles

Why are new offers APRs higher than existing account APRs?
Kamila [148]

Answer:

The APR reflects the interest rate plus the fees you paid directly to the lender or broker or both: origination charges, discount points and any other costs. Those fees add to the cost of the loan, and APR takes them into account. That's why APR is higher than the interest rate.

Have a good day
