Answer:
228 butterflies
Step-by-step explanation:
X represents the moths
2x represents the butterflies
solution:
x + 2x = 342
3x = 342
x = 114
2x = 228
so therefore Alex have 228 butterflies
Answer:
r =5 in
Step-by-step explanation:
Area of a circle is given by
A = pi r^2
We know the area and pi
78.5 = 3.14 r^2
Divide by 3.14
78.5/3.14 = 3.14 /3.14 r^2
25 = r^2
Take the square root of each side
sqrt(25) = sqrt(r^2)
5=r
The denominator is supposed to be 15 so do 3/5x3=9/15
So she must attend at least 9 classes
Answer:
Value of y = 7
Step-by-step explanation:
By the midpoint theorem of the triangles,
"Segment joining midpoints of the two sides of a triangle is parallel to the third side and measure half the length of the third side."
Therefore, from the figure attached,
In ΔFGH,
J and K are the mid points of the two sides GH and FH.
By theorem, segment JK║GF and m(JK) =
(5y + 3) = 2(2y + 5)
5y + 3 = 4y + 10
5y - 4y = 10 - 3
y = 7
