Set up the ratio for N.A butterflies to S.A butterflies: 5/3=30/x. Solving for x, you get that there are 18 S.A butterflies.
Set up the equation 3/2=30/x. Solving for x, you get that there are 20 European butterflies.
Answer:
a) m = (24 - 16 / 3 - 2) = 8/1
b) each roller coaster car holds 8 passengers.
The answer to this question is c
Answer:
just use the concept that if two lines are perpendicular then product of slopes is -1
then you can find slope of other line by using -1/m1
where m1 is slope of the line given
then for that m2.use 2 point form of a line to find it's equation which passes through (4,-6)
Given,
LP = 15, PR = 9
Point P lies on the line segment PR. It would mean that,
LP + PR = LR
⇒LR = 15 + 9
⇒ LR = 24
Hence, "LR = 24 because LP + PR = LR according to the Segment Addition Postulate, and 15 + 9 = 24 using substitution" is the correct option.
