1/2=x/20
times both sides by 20
20/2=x
10=x
answer is 10/20
Answer:
50 years old
Step-by-step explanation:
The BC/AD time line is like a number line: the negative side of 0, the numbers move backwards; and the positive side of 0 moves normally. If you have -25, then move to +25, you have just moved 50 places.
Hope this helps :)
5/5 because 7/8-2/3 equals 5/5 what you are doing you are taking away you take away 2 from the 7 and take away 3 from the 8 so there is your anwser 5/5 hope this helped! :D
(1/12) / (1/3) = 1/x....now just solve it like a proportion.....oh, and x represents the number of hrs it would take to fill the whole tank
Answer:
a. 43.96 feet
b.153.86 square feet
Step-by-step explanation:
Hi, the path through the middle of the circular garden is the diameter.
Since the diameter is equal to:
Diameter = 2 radius (r)
Solving for r
14 =2r
14/2 = r
r = 7 feet
The distance around the outside of this garden is the perimeter.
Perimeter of a circle (P) = 2 π r
Replacing with the values given:
P = 2 (3.14) 7 = 43.96 feet
b. area of the circle-
Area of a circle (A)= π r²
Replacing with the values given:
A = 3.14 (7²) =153.86 square feet
