Answer:
- Sand in small bag = 2x = 2(7.5) = 15 kg
- Sand in medium bag = 3x = 3(7.5) = 22.5 kg
- Sand in a large bag = 7x = 7(7.5) = 52.5 kg
Step-by-step explanation:
Total weight = 90 kg
As 90 kg has been distributed in 3 bags in the ratio 2:3:7
Let the small bag contains = 2x
Let the medium bag contains = 3x
Let the big bag contains = 7x
so the equation becomes
2x+3x+7x = 90
12x = 90
x = 90/12
x = 7.5
Thus,
- Sand in small bag = 2x = 2(7.5) = 15 kg
- Sand in medium bag = 3x = 3(7.5) = 22.5 kg
- Sand in a large bag = 7x = 7(7.5) = 52.5 kg
<u>SOLUTION CHECK</u>
15+22.5+52.5=90 kg
Answer:
12
Step-by-step explanation:
To find perimeter, add the lengths of each side. 5 + 4 + 3 = 12
Answer:
A. 11160 cubes B. 1395cm^3
Step-by-step explanation:
Volume= length x width x height
Its easiest to solve B. first and use it to solve A.
B. 7.5 x 12 x 15.5 = 1395cm^3 (volume of prism)
A. .5 x .5 x .5 = 1/8cm^3 (which is the volume of the cube)
1395 ÷ 1/8 = 11160
