What is the volume of a cylinder with a base and height of 13 in?? PLZ HELP QUICK
Helga [31]

Answer:

V = 549.25 pi = 1,724.645in^2

Step-by-step explanation:

If both the base and height are equal, then you must use the given equation:

V = pi * r^2 * h

V = pi * (1/2 13)^2 * 13

V = pi * 6.5^2 * 13

V = 549.25 pi = 1,724.645in^2

If log10(x^{2}y^{3})=7 and log10 (x/y)=1 , then x=__ and y= __
yuradex [85]

Answer:

x=100

y=10

Step-by-step explanation:

we are given

log_1_0(\frac{x}{y})=1

Firstly, we will get rid of log

so, we will take exponent over 10 on both sides

10^{log_1_0(\frac{x}{y})}=10^{1}

now, we can simplify it

\frac{x}{y}=10

now, we can solve for x

x=10y

we are given

log_1_0(x^2y^3)=7

Firstly, we will get rid of log

so, we will take exponent of 10 on both sides

10^{log_1_0(x^2y^3)}=10^7

x^2y^3=10^7

now, we can plug back x from first equation

(10y)^2y^3=10^7

now, we can solve for y

100y^5=10000000

\frac{100y^5}{100}=\frac{10000000}{100}

y^5=100000

now, we can take radical 5

y=\sqrt[5]{100000}

y=10

now, we can find x

x=10\times 10

x=100

So, solution is

x=100

y=10

There are 8 marbles in a bag. Each marble is a different color. The colors are: red, orange, yellow, green, blue, purple, black,
saveliy_v [14]

Answer:

B. 1/56

Explanation:

There are 8 different marbles. In the first draw, you have a one out of 8 chance of getting the red. In the second draw, there are 7 marbles remaining, so a one out of 7 chance of drawing a white marble. To find the total probability of drawing the red and then white marble, we multiply the probabilities if each draw.

(1/8)*(1/7)=1/56

Is 1/3 bigger than 5/6
adell [148]
No because in 1/3 you get 2/6 so if you have 1/3 vs. 5/6 than you only have 1/3 containing 2/6 and we are looking for 5/6 so that is wrong. 5/6 is bigger that 1/3.
