500
Step-by-step explanation:
400 x 1.25 = 500 or just 400x0.25 +400
Answer:
The volume of a cylinder = 78 \mathrm{cm}^{3}78cm3
Let us substitute the volume of cylinder in the formula.
The formula for volume of a cone is V=\frac{\pi r^{2} h}{3}V=3πr2h (1)
The formula for volume of a cylinder is V=\pi r^{2} hV=πr2h (2)
Substituting V=78V=78 in equation (2), we get,
\begin{gathered}\begin{array}{c}{V=\pi r^{2} h} \\{78=\pi r^{2} h}\end{array}\end{gathered}V=πr2h78=πr2h
Given that the cone has the same radius and height of that of the cylinder, let us substitute 78=\pi r^{2} h78=πr2h in equation (1)
\begin{gathered}\begin{array}{l}{V=\frac{\pi r^{2} h}{3}} \\{V=\frac{78}{3}} \\{V=26}\end{array}\end{gathered}V=3πr2hV=378V=26
Thus, the volume of a cone with the same radius and height of a cylinder is 26 \mathrm{cm}^{3}26cm3 .
we know the rocket was launched from the ground, meaning its initial height is 0, thus

Answer:
0.624999999(repeating) so i would round it to 0.625 or 0.63 (both work and are rounded, its really up to wherever your teacher wants you to round it to if they want you to round it)
Step-by-step explanation:
2/3 x 1/2 (3/4 ÷ 2/5)=
simplify the parentheses (3/4 ÷ 2/5) to 1.875
2/3 x 1/2 x 1.875=
simplify 2/3 x 1/2 to 0.333333(repeating)
0.3333333333 x 1.875 = 0.6249999999(repeating)
round it to 0.625 or 0.63 (which ever one your teacher wants you to round it to)
Answer: D
Just add 10 zeros behind the 6.
You get 60,000,000,000
Checking this with a calculator verifies this is the correct answer.
