Answer:
D
Step-by-step explanation:
The best way to work with fractions is to turn them into decimals by dividing the numerator by the denominator.
Volume of cone canbe calculated using the following rule:
volume of cone = (1/3) x pi x (radius)^2 x height
from the givens:
pi = 22/7
I'll assume that the 10 cm refers to the height
radius = 16/2 = 8 cm
substitute in the equation to get the volume as follows:
volume=(1/3) x (22/7) x (8x10^-2)^2 x (10x10^-2)
= 6.7 x 10^-4 m^3
Answer: If the class sold c cards, the inequality that represents their profit goal is [20c - 0.2 > 10,000]
This year’s class sold 520 cards, so they [met] their goal because they sold more than [505] cards.
Step-by-step explanation:
When reflecting a point across the x-axis, you multiply the y coordinate by -1 (you flip the sign), so (-8,-3) would turn into (-8,3).
When reflecting a point across the y-axis, you multiply the x coordinate by -1 (flip the sign), so (-8, -3) becomes (8, -3)
X equals seven, hope this helps
