Answer:
Step-by-step explanation:
<u>Given</u>
- x : y = 2 : 5, y is 80% of z
<u>Rearranging the ratios:</u>
- x/y = 2/5 ⇒ x/y = 0.4 ⇒ y = x/0.4 ⇒ y = 2.5x
- y is 80% of z ⇒ y = 0.8z
<u>Comparing the values of y:</u>
- 2.5x = 0.8z
- x/z = 0.8/2.5
- x/z = 0.32
- x/z = 32/100
- x/z = 8/25
- x : z = 8 : 25
Answer:
32 cubic meter
Step-by-step explanation:
Volume for any pyramid is given by following expression
volume of pyramid = 1/3( area of base of pyramid * height of pyramid)
________________________________
In the problem
base area of pyramid = 24 sq. m
height = 4 m
Therefore substituting the above given value in formula for volume of pyramid we have
volume of pyramid = 1/3( 24 sq. m * 4 m) = 8 sq. m * 4 m (since 24/3 = 8)
volume of pyramid = 32 cubic meter.
Answer:
Same
Step-by-step explanation:
The number of days is 10 if, on a poultry farm, 50 hens give 200 eggs in 2 days.
<h3>What is the ratio?</h3>
It is described as the comparison of two quantities to determine how many times one obtains the other. The proportion can be expressed as a fraction or as a sign: between two integers.
It is given that:
On a poultry farm, 50 hens give 200 eggs in 2 days.
It is required to find the number of days will 20 hens require to give 400 eggs:
Let x be the number of days:
(50×2)/200 = (20x)/400
x = 10
Thus, the number of days is 10 if, on a poultry farm, 50 hens give 200 eggs in 2 days.
