Answer:

You have to make h the subject using volume of cone formula :

v =  \frac{1}{3}  \times \pi \times   {r}^{2}  \times h

3v = \pi {r}^{2}  \times h

\frac{3v}{\pi {r}^{2} }  = h

h =  \frac{3v}{\pi {r}^{2} }

Question help a lottery game has balls numbered 0 through 1313. what is the probability of selecting an even numbered ball or a
Licemer1 [7]
So i'm assuming 33^a is saying any number that is a square of 33 inside of 1,313 so first, to find how many even numbers divide 1,313 by two to get 656.5 so if I am not mistaken 656 numbers in 1,313 will be even. Now find all squares of 33 that don't pass 1,313 which is 33 itself and 1,089 because 33^3 is 35,937 so add 2 to 656 to get 668. so the probability is 658/1,313 i believe.

Help me out with number 8!!! I’m confused and I need this by tomorrow HELP PLEASE

We can use elimination for these set of systems.
First, we need to set up our variables.
Belts=b
Hats=h
Now, the situation is 6 belts and 8 hats for $140. The situation after is 9 belts and 6 hats for $132.
Let’s set up our system of equations.
6b+8h=140
9b+6h=132
We need to eliminate a variable. Since b has coefficients of 6 and 9, we can easily eliminate b by multiplying the top equation by 3 and the bottom by -2.
18b+24h=420
-18b-12h=-264
Now let’s add.
12h=156
Let’s divide to get h by itself.
156/12=13=h
So a hat costs $13. We need to put in 13 for one of the equations so we can find the cost of a belt.
9b+6(13)=132
9b+78=132
We need b by itself.
9b=54
54/9=6
Belts are $6
We can also use the first equation to check our answers.
6(6)+8(13)
36+104
140.
So, the price of a belt is $6 while the price of a hat is $13.

A scale drawing for a plot of land is shown below.
Vitek1552 [10]

The area of real backyard is 72 square meters.

Step-by-step explanation:

Given,

Length of rectangular backyard = 8 cm

Width of rectangular backyard = 4 cm

According to scale;

2 cm = 3 m

1 cm = \frac{3}{2} = 1.5\ m

Real length of backyard = 8*1.5 = 12 m

Real width of backyard = 4*1.5 = 6 m

Real area of backyard = Length * Width

Real area of backyard = 12*6 = 72m²

The area of real backyard is 72 square meters.
