How do I find X in this problem

pogonyaev

You know that BC is congruent to x so you need to solve for x using the ratio:
$\frac{12}{24}=\frac{x}{BC}$

So then we need to find BC.

We know:
$A=\frac{base \times height}{2}$
$28=\frac{BC \times 7}{2}$
Therefore BC =8

Then:
$\frac{12}{24}=\frac{x}{8}$
$x=8 \times \frac{12}{24} = 4$

1) The probability of getting a queen is 187/10000 which is 0.0187 = 1.87%

2) The probability is 449 / 479 which is 0.937 = 93.7%

You may need to round the answers. It doesn't say if they need to be rounded or not.

if a right circular cone has a volume of 15 cubic ft and a radius of 3 ft, what is the height of the cone?

Setler79 [48]

Volume of cone=1/3 times height times pir^2
v=15
r=3
15=1/3 hpi3^2
15=1/3hpi9
15=9/3hpi
15=3hpi
divide 3
5=hpi
h=5/pi
pi=aprox 3.14
5/3.14=1.59

1.59 ft
