Answer:
approximately 10
Step-by-step explanation:
Volume = 1/3h times 
times radius square
1570 = 1/3 x 15 x 22/7 x 
1570 = 5 times 
times
1570 = 15.71
= 
99.9 = r^2
= r
≅10
Assuming the order does not matter, you want the number of combinations of 9 things taken 5 at a time. The combinations can be shown as C(9,5), 9C5.
C(9, 5) =
9/5(9-5) =
9*8*7*6*5 / 5*4
The 5 terms cancel.
9*8*7*6 / 4*3*2 =
9*7*2 =
126
The above change is because 4*2 cancels the 8 in the numerator and 6/3 = 2
Therefore, the solution is 126.
Answer:
if that statement is true, then DE=ST, and ST=4 so your answer should be <u>DE=4</u>
Explanation:
you can tell that they are even from looking at the first statement, it states <u>DE</u>F=<u>ST</u>U, emphasizing on the DE=ST part, it gives your the answer right there because ST=4
