If 40% are boy and there are 12 boys
40% of girls would be 12 and another 20% is 6 so
You add 12+12+6=30 students total
Step-by-step explanation:
but sorry i can't get the answer of (2x-1) =3 (x+5) because the answer of this came -16
Answer:
Not a function
Step-by-step explanation:
Y values can repeat in a function but domain cannot. 3 is repeated twice, thus these values do not represent a function.
Given the radius, circumference can be solved by the equation, C = 2πr. The circumference of the circle above is C = 2π(8 in) = 16<span>π in. To solve for the length of the segment joining the arc is the circumference times the ratio of central angle and 360 degrees.
Length of the segment = (16</span>π in)(60/360) = 8/3 <span>π in
Thus, the length of the segment is approximately 8.36 in. </span>
The sum exterior angles of a square are:
4*90=360°
