I need help ASAP!!

Dmitrij [34]

Suggestion:

The width is the x value and the hight is the y value.

Plot the points on the graph as decimal if that helps.

The point at the bottom left is the origin (0,0)

I hope this helps.

A silo is a composite of a cylindrical tower with a cone for a roof. What is the volume of the silo if the radius of the base is

kirza4 [7]

Answer:

The answer is b. 343,480.8ft

Step-by-step explanation:

I thought it was c at first because I forgot to add the volume of the cone.

The equation for the volume of a cylinder is V=π×r²×h

The solution would look like V=π40²×65=326725.8

The equation for the volume of a cone is V=1/3πr²×h

The solution would look like V=1/3π×40²×10=16755

Adding the two volumes would equal 326725.8±16755= 343480.8

you pick a card at random without getting the first card back you pick a second card at random what is the probability of pickin

Keith_Richards [23]

We have to calculate the probability of picking a 4 and then a 5 without replacement.

We can express this as the product of the probabilities of two events:

• The probability of picking a 4

• The probability of picking a 5, given that a 4 has been retired from the deck.

We have one card in the deck out of fouor cards that is a "4".

Then, the probability of picking a "4" will be:

$P(4)=\frac{1}{4}$

The probability of picking a "5" will be now equal to one card (the number of 5's in the deck) divided by the number of remaining cards (3 cards):

$P(5|4)=\frac{1}{3}$

We then calculate the probabilities of this two events happening in sequence as:

$\begin{gathered} P(4,5)=P(4)\cdot P(5|4) \\ P(4,5)=\frac{1}{4}\cdot\frac{1}{3}=\frac{1}{12} \end{gathered}$

Fudgin [204]

Find area of lumber 2 x 10 = 20
garage needs 324 feet, rec room needs 430, bonus room needs 283
324 + 430 + 283 = 1037
1037/20= 51.85 feet of lumber
