Answer: 32 2/19°F
Step-by-step explanation:
Since the temperature was 52° and dropped to 38°, the difference will be:
= 52° - 38°
= 14°
Therefore, 14° was dropped in 4¾ hours. Therefore, the temperature dropped pee hour will be:
= 14/4¾
= 14 / 19/4
= 14 × 4/19
= 56/19
= 2 18/19° per hour.
In 2 hours, the temperature dropped will be:
= 2 18/19° × 2
= 5 17/19°
With the above explanation, the temperature after 2 hours will then be:
= 38° - 5 17/19°
= 32 2/19°F
The temperature will be 32 2/19°F.

Answer:
C,20%
Step-by-step explanation:
First we are told that she has 3 hours to grade 35 student papers ,and she has 30 minutes to grade 5 paper, now we calculate how long it took her to grade 1 paper.
Part1
if 5papers = 30minutes
therefore 1paper = (30*1)/5 = 6mins per paper.
now we are left with 2hrs 30mins(150 mins) to grade 30papers
Part2
if 30papers = 150minutes
therefore 1paper = (150*1)/30 = 5mins per paper.
to calculate how fast she has to be in relation to the first part
we substract :
(6mins- 5mins)/ 5mins *100 =1/5 * 100 = 20%.
Solution:
<u>Step-1: Find the area of the pizza.</u>
- Area of pizza = πr²
- => πr² = π x 9 x 9
- => 81π = Area of pizza
<u>Step-2: Find the area of the slice.</u>
- = 81π/6 = Area of slice
- => 27π/2 = 13.5π = Area of slice
Option D is correct.
