Please see the pic, I'd solved in it.
Answer:
The formula for the volume of a cylinder is V=Bh or V=πr2h .
Answer:
<em>There are 12 students.</em>
Step-by-step explanation:
This is because there are 4 students per team, and there is 3 teams.
So...
3 * 4 = 12 students
The <em><u>correct answers</u></em> are:
B- x + y ≤ 10
; and D- x ≥ 4
Explanation:
The illusionist needs at least 4 female volunteers. This means he could use 4 or more; this means x, the number of female volunteers, is greater than or equal to 4:
x ≥ 4
The total of number of volunteers needed is up to 10. This means the illusionist can use 10 or fewer people; this means the total is less than or equal to 10.
The number of female volunteers is x and the number of male volunteers is y; together they create the expression x+y. This gives us
x+y ≤ 10
