Answer:
50.27
Step-by-step explanation:
Question 4:
2x-3
Because we don’t know how much Fernando has that would be where we fill in the variable giving you 2x then 3 dollars less will give you the -3 therefore 2x-3
Question 5:
1/2x+7
Because we don’t know Deb’s age that would be the variable and we are looking for half of Deb’s age giving you 1/2x then the 7 years more giving you the +7 hence 1/2x+7
So, for the semi circle, we need to find the area of a circle then divide it by 2.
pi times r squared
is the area of a circle with the radius of 4
(I'm going to use 3.14 as pi)
So 3.14 times 16 is 50.24
Divide that by 2 and we get 25.12
For the rectangle at the bottom. We know that the radius is four, so we can cut off 4ft from the height, leaving us with 8.
8 times 8 is 64.
To find the area of the whole figure, we add 64 and 25.12 together, getting 89.12
So the area is 89.12 feet squared.
Any questions?
Answer: Have you figured out the answered cuz I need it to please?
Step-by-step explanation:
Answer:
14. 1 inch = 96 miles (12 × 8)
1/2 inch = 48 miles (96 ÷ 2)
96 + 48 = 144 miles
3 3/4 = 3.75
144 ÷ 3.75 = 38.4
A. 38.4 mph
15. Adding a negative number is the same as just subtracting.
D. 35(2) - 1/2(15)
20. - = withdrew because you are subtracting
+ = deposited because you are adding
D. Peter withdrew $47.27 and deposited $598, increasing his bank account by $550.73
21. Yana: 7 - 3 + 6 - 1 + 8 - 2 = 15
15 ÷ 6 = 2.5 average
Amber: 1 + 5 - 2 + 4 - 2 + 6 = 12
12 ÷ 6 = 2 average
2.5 - 2 = 0.5
A. Yana's average number of points is 0.5 point greater than Amber's
