Answer: D
Step-by-step explanation:
The number generator is not fair, in most of the experiments, considerably less than 60 % of the selected marbles are green.
And if Sixty percent of the marbles in the jar are green. A number generator should simulates randomly by selecting atleast one of the 60% of green marbles from the jar
C:t=2:3
t:h=2:1
multiply first equation by 2 and 2nd by 3
c:t=4:6
t:h=6:3
so
c:t:h=4:6:3
if t is 4 more than c
t is 6 units and c is 4
6-4=2
so 4=2 units
2=1 unit
hollly is 3 units
3*2=6

Answer:
100
Step-by-step explanation:
start with what's in the parenthesis':
8 (9.75 - 3.25) + 12 x 4 = 8 (6.50) + 12 x 4
then take the number outside of the parenthesis' time the number inside of them:
8 (6.50) + 12 x 4 = 52 + 12 x 4
now, take the product of the two number on the right side of the addition sign:
52 + 12 x 4 = 52 + 48
finally, add the final two numbers together:
52 + 48 = 100
Answer:
Option D. 5890.5 feet²
Step-by-step explanation:
An individual head of a sprinkler system covers a circular are of grass with a radius of 25 feet.
Yard has three sprinkler heads that each cover circular area with no overlap.
We have to calculate the approximate area watered by these 3 sprinkler heads.
Area covered by one sprinkler = π×r² = π×(25)² = 625π feet²
Therefore area covered by three sprinkler heads = 3 × 625π = 5892.85 feet²
which matches the approximate value of Option D. 5890.5 feet²
