Answer:
The question says area of a square = 9 cm squared.
And they said if the sides are doubled in length what is the new length
so new length = 9 cm^2 × 9 cm^2
which should give you 81cm^2
therefore your answer should be = C
Answer:
The volume of the ball is 256 cm³
Step-by-step explanation:
we know that
The density is equal to the ratio of the mass by the volume
D=m/V
Solve for V
The volume is equal to the ratio of the mass by the density
V=m/D
In this problem we have
m=128 g
D=0.5 g/cm³
substitute
V=128/0.5=256 cm³
Answer:
Your answer is C. 1/2 (16*6) = 48 square feet
Step-by-step explanation:
The formula to find the area of a triangle is A = b*h/2 (base times height divided by half)
First you need to multiply the base (6) by the height (16).
6*16 is 96.
Now you divide 96 by 2 or cut it in half.
96/2 (or cut in half) is 48.
Therefore your answer is C
Answer: 94 cm^3.
Step-by-step explanation: You use the formula 2(ab+bc+ca). You plug in 3, 4, and 5 to get 94.
Answer:
1. 15, 13
2. 12, 6
3. 130,135
4. 44, 41
5. 42, 52
Step-by-step explanation:
1. the answer is 15,13 because the sequence goes with minus 2
2. the answer is 12,6 because the sequence goes with divided by 2
3. the answer is 130,135 because the sequence goes with plus 5
4. the answer is 44, 41 because the sequence goes with minus 3
5. the answer is 42,52 because the sequence goes with plus 10
