Answer:
12 units^3
Step-by-step explanation:
V=1/3Bh
=1/3 Area of the base times height
Area of base: r^2=4
height=9
4 times 9=36
1/3 of 36 =12
Answer:
1. There are a total of 19 marbles in the bag. The probability of picking a green marble out of them is 4/19 since there are only 4 green ones. The probability of picking a brown marble after replacing what has been initially picked is 1/19. The final probability is the product of the two probabilities and that is 4/361.

Answer:
Measure of angle ADC is 70°
Step-by-step explanation:
So, we know that the overarcing angle BDA equals 110°. And then, we have these two equations that split up this overarcing angle. To solve for x, all we need to do is say is that the sum of these two equations are equal to 110°
2x+10+3x+25=110
Combine like terms
5x+35=110
Subtract 35 from both sides
5x=75
Divide by 5 on both sides
x=15
Now, to find the measure of angle ADC, simply plug 15 in for x on that equation:
3(15)+25
So, the measure of angle ADC is 70°
The answer is: t = 1
You need to separate t from everything to figure out what it is.
Step 1: Subtract 9 from both sides, so we get 7 - 2t = 5t
Step 2: Add 2t to both sides, so we get 7 = 7t.
Step 3: Divide by 7, meaning t = 1.
Next you should check your work. If we plug 1 in for t, we get 14 = 14, so the answer is correct.
Hope this helps!
Answer:
The distance is 3
Step-by-step explanation:
It can be demonstrated that the distance is 3 by performing the operation to obtain the distance between two points.
Where (x2,y2)=(0,0) since it is the origin.
(x1,y1)=(0,-3)
We can see that = 0
And that = 9
Hence the distance is 3
