A card is drawn from a standard deck of
Gala2k [10]

Step-by-step explanation:

Total number of outcomes = 52 , since each deck consists of 52 cards

probability = Number of favorable outcomes/ Total number of outcomes

a) Number of favorable outcomes = Number of club cards = 13

P(club) =13/52 = 1/4

b) Number of favorable outcomes = Number of red cards = 26

P(red card) = 26/52 = 1/2

c) Number of favorable outcomes = Number of cards that are not hearts = 39/52 = 3/4

A punch recipe says to mix 4 cups pineapple juice 8 cups orange juice and 12 cups seltzer in order to make 18 servers of punch.H

81 servings. I found this by making a ratio:
24 c            108 c
-------     =    -------
18 ser            x
I then cross multiplied to get the equation: 24x=1,944. I solved this equation to find x, the number of servings in 108 cups, which was 81. 

I remember doing this back in elementary school. I had a hard time with it too!

the volume of the cone is 25.12cm cubed, and the area of the base is 12.56cm squared.what is the height
Lady bird [3.3K]

Height of the cone having volume as 25.12 \text { cm}^{3} and base area 12.56 \text { cm}^{2} is 6 cm.

Solution:

Given that volume of cone = 25.12 \text{ cm}^{3}

Area of base = 12.56 \text { cm}^{2}

Need to determine height of the cone.

Formula for volume of the cone is as follows

\mathrm{V}_{c}=\frac{1}{3} \pi r^{2}{h} \rightarrow (1)

Area of circular base of cone = A_{b}=\pi r^{2}

Replacing \pi r^{2} \text { by } A_{b} in equation (1), we get

\mathrm{V}_{\mathrm{c}}=\frac{1}{3} \mathrm{A}_{\mathrm{b}} \mathrm{h}

\Rightarrow \frac{3 \mathrm{V} c}{\mathrm{A}_{\mathrm{b}}}=h

\Rightarrow h=\frac{3 \mathrm{v} c}{\mathrm{A}_{\mathrm{b}}} \rightarrow (2)

In our case Volume of cone V_c= 21.12 \text{ cm}^3 and Area of base A_b=12.56 \text { cm}^2

On substituting the values of volume and area in equation 2 we get

h=\frac{3 \times 25.12}{12.56}=6 \text{ cm }
