For #2, the proportion would be .40/.25 and x/15, then you would cross multiply to find x. and for #3 the proportion would be 15/6 and 75/x and again you would cross multiply to find x. (:
Answer:
0.40 x 50
Step-by-step explanation:
40% is of 1 so it can be rewritten as 0.40
Contraction if the scale factor is <1 (0.25, 0.8, 0.375)
<span>Expansion if the scale factor is >1 (1.5, 4, 1.75 )
0.25<1
0.8<1
0.375<1
1.5>1
4>1
1.75>1</span>
Answer:
The answer is D.
Step-by-step explanation:
First, we take the info we know. We know that this of multiplication. That means we can rule out A and E.
Now, we need to take the definition of the associative property. The associative property means that you keep the same numbers, variables, and operations, but you switch the grouping. This means that the answer is D. This is because, on both sides of the equation, we keep the same numbers variables and operations. However, on one side we have 4 grouped with r, and on the other, we have 3 grouped with 4. We switched our grouping but kept the expression. This means that our answer is D.
Answer:
or 763 cubic feet.
Step-by-step explanation:
The tank is cylindrical and the volume of a cylinder is given as:

where r = radius and h = height
The radius, r, of the tank is 4.5 ft and the height, h, of the tank is 12 ft.
Therefore, the volume of the cylindrical water tank is:

Approximating to whole number, the volume of the tank is
or 763 cubic feet.
