Answer:
VA = 2/3πrB²hB
Step-by-step explanation:
Let the volume of cosA ad cone B be expressed as;
Va = 1/3πra²ha
Vb = 1/3πrb²hb
If the radius of the base of cone A is twice as large as the radius of the base of cone B
rA = 2rB
If the height of cone B is twice the height of cone A, then;
hB = 2hA
hA = hB/2
Recall that;
VA = 1/3πrA²hA
VA = 1/3π(2rB)²(hB/2)
VA = 1/3π*4rB²(hB/2)
VA = 2/3πrB²hB
This gives the volume of cone A
You could do 20 divided by 10 times 2 plus 1 to get 30
Answer:
It is the third option.
Step-by-step explanation:
First, the shaded part is above the line, so there must be a y>, ruling out two of our options. so now, the slope of the line is the only missing item. Use the points (0,3) and (3,5). m=(y2-y1)/(x2-x1), so m = -2/-3, which simplifies to 2/3. Therefore, y>2/3x + 3 is your answer.
Hope this helps!

![x = 105 \\ is \: the \: correspoding \: angel \\ \\ (3z - 9) + 105 = 180 \\ \\ 3z - 9 + x= 180 \\ \\ 180 - 96 \\ \\ 3z = 84 \\ \\ z = \frac{84}{3} \\ \\ z = 28](https://tex.z-dn.net/?f=x%20%3D%20105%20%5C%5C%20is%20%5C%3A%20the%20%5C%3A%20correspoding%20%5C%3A%20angel%20%5C%5C%20%20%5C%5C%20%283z%20-%209%29%20%2B%20105%20%3D%20180%20%5C%5C%20%20%5C%5C%203z%20-%209%20%2B%20%20x%3D%20180%20%5C%5C%20%20%5C%5C%20180%20-%2096%20%5C%5C%20%20%5C%5C%203z%20%3D%2084%20%5C%5C%20%20%5C%5C%20z%20%3D%20%20%5Cfrac%7B84%7D%7B3%7D%20%20%5C%5C%20%20%5C%5C%20z%20%3D%2028)
because x = 75 is the corresponding angel
and x value was 75 then (3z-9) was straight angel they are sum was 180 degree. my answer was wrong please report
Answer:
A good prediction is that the number 5 will be rolled 8 times
Step-by-step explanation:
Here, we want to get the number of times 5 would occur in a roll of 50
firstly, we need the probability of having a 5 come up
To do this, we have to divide the number of 5’s by the count of possible numbers
We have this simply as 1/6
Now, we have to multiply this by 50
we have this as;
1/6 * 50 = 8.333
This is approximately 8
so we have it that in 50 rolls, we can have the number 5 coming up 8 times
