3/30=9/v
3×3=9
30×3= 90
v=90
Answer:
1.33 liters
Step-by-step explanation:
Volume of any shape is given by cross sectional area multiplied by height. Therefore, V=Ah
Where A is area and h is height
Since their cross sections are the same, then volume depends on height.
If 12cm equals 2 liters
8cm equals x
X=(2*8)/12=1.3333333333333 liters
Approximayely, the smaller pail has capacity of 1.33 liters
Answer:
Pretend that x and y represents the 2 numbers that we need to find.
According to the information, we know that:
x + y = 21
6x = y
Replace y in the first equation with 6x (because they are equal to each other according to the second equation):
x + y = 21
x + 6x = 21
7x = 21
x = 21/7 = 3
Now have two ways to find y, both will give us the same result:
3 + y = 21 ⇔ y = 21 - 3 = 18
6 · 3 = y ⇔ y = 18
So the numbers that we need to find are 3 and 18.
