Answer:
78.75 cm³
Step-by-step explanation:
Volume = Width × Height × Length
V = 5 × 4.5 × 3.5
V = 78.75 cm³
Answer:
Area =
Step-by-step explanation:
We let the width of the pool be "w"
We know the length is twice as long as width, so the length is:
2w
So,
Width = w
Length = 2w
Since a sidewalk with 2 feet width goes around the pool completely, the area enclosed by pool + sidewalk would have 2 feet around it, so its length and width would be:
Width = w + 2 + 2 = w + 4
Length = 2w + 2 + 2 = 2w + 4
The area of a rectangular region is always length * width, so the expression for area of pool and sidewalk would be:
If we let the width of the swimming pool be "w", the expression for the area of pool and sidewalk is:
Area =
Answer:
<h3>
9t + (t + 2) </h3>
Step-by-step explanation:
the product of 9 and t is: 9•t
the sum of t and 2 is: t+2
increasing means adding, so:
the product of 9 and t increased by the sum of t and 2 would be:
<u>9t + (t + 2)</u> = 9t + t + 2 = 10t +2
Answer:
Of the total 31 + 20 + 6 + 6 + 6 = 69 medals, the USA won 31 of them. 31/69 as a percentage is about 45%. Since there are 360° in a full circle, 45% of that is 0.45 * 360 = 162°.
