B)257.1
Explanation: Area of a square : length x width
Area of square = 12x12= 144
Area of a circle: pie(radius)^2
diameter:12
radius:12/2=6
Area of a circle: pie(6)^2=113.1
ADD BOTH AREAS
Area of the figure =144+113.1
=257.1
Answer: 615.4
Step-by-step explanation:
if the radius is 14
5 times 2 times 8 would equal 80
Answer :80
Answer:
x = 6
y = 2
Explanation:
To solve the system using elimination, we need to multiply the second equation by -1, so the second equation is equivalent to:
x - 9y = -12
-1 (x - 9y) = -1 (-12)
-x + 9y = 12
Then, we can sum this equation and the first equation. So:
5x - 9y = 12
-x + 9y = 12
4x + 0 = 24
So, we can solve for x, as:
4x = 24
4x/4 = 24/4
x = 6
Then, we can replace x by 6 on the first equation and solve for y, so:
5x - 9y = 12
5(6) - 9y = 12
30 - 9y = 12
30 - 9y - 30 = 12 - 30
-9y = -18
-9y/(-9) = -18/(-9)
y = 2
Therefore, the solution of the system is x = 6 and y = 2
Answer: 75%
Step-by-step explanation:
35% of 5 liters is 1.75 liters
1.75 liters + 8 liters = 9.75 liters (only juice)
(5 liters + 8 liters = 13 liters) (the whole thing)
So, 9.75/13 is 75%
