Answer:

\frac{1}{25}

Step-by-step explanation:

the probability that the first card will be red and the second card will be blue:

p(red then blue) = p(red) × p(blue)

                          =\frac{1}{5} *\frac{1}{5}

                          =\frac{1}{25}

What is the volume of a cylinder, in cubic centimeters, with a height of 8 centimeters
Arisa [49]

Answer:

1608.5 cm³

Step-by-step explanation:

Use the cylinder volume formula, V = \pir²h

If the diameter is 16 cm, then the radius is 8 cm.

Plug in the radius and height into the formula, and solve:

V = \pir²h

V = \pi(8)²(8)

V = \pi(64)(8)

V = 1608.5

So, to the nearest tenth, the volume of the cylinder is 1608.5 cm³

Please help thank you.

Hello!

To solve this we use the equation sin60 = (s/2) / (d/2)

s is a side of the triangle
d is the diameter

sin60 = s/d

\sqrt{3/4} =s/d

d=s/ \sqrt{3/4}

d = s \sqrt{4/3}

d = 2s/ \sqrt{3}

put 6 in for s

d=12/ \sqrt{3}

d =  \sqrt{48}

d = 6.9

The answer is C) 6.9

Hope this helps!

Tell how you know when you have found the prime factorization of a number
sweet-ann [11.9K]
When you end up with prime numbers for example
If you factored out 12 you could say 3x4. Now 3 is a prime number so it cant be broken down any more. You can break down 4 into 2x2. 2 is a prime number so cant be broken down any further. When 12 is factored out it is 2x2x3
