Answer:
27,320,832
Step-by-step explanation:
It is $0.49 per square feet
You need 55,756,800 square feet
Multiply 55,756,800 x 0.49 = 27,320,832
3 + 3 + 5 = 11 (11 total parts of the ratio.)
132 ÷ 11 = 12 (one part of the ratio)
Multiply 12 by the number of parts in the ratio:
12 × 3 = 36
12 × 3 = 36
12 × 5 = 60
Therefore, the final answer is 36:36:60 kg.
The number of red marbles in the bag is 19 and the number of blue marbles is 8.
<u>Explanation:</u>
Let R be the number of red marbles
Let B be the number of blue marbles
According to the question,
R + B = 27 (Total number of marbles is 27
) -1
R = 3B - 5 (Number of red marbles is 5 less than 3 times the number of blue marbles
)
Substitute the right half of the second equation for R in the first equation
3B - 5 + B = 27
Add 5 to each side and combine the Bs
4B = 32
Divide both sides by 4
B = 8
Use this value of B in the first equation
R + 8 = 27
R = 19
Therefore, number of red marbles in the bag is 19 and the number of blue marbles is 8.
