Answer:
90 red cars, 150 blue cars
Step-by-step explanation:
Divide 240 by 8. 8 comes from the 3:5 ratio (3+5). 240/8=30. 30x3=90, 30x5=150.
Answer:

Step-by-step explanation:
The following piecewise functions are linear functions. The graph of any of them is a line segment.
We just need to calculate the value of the function at each end specified in the brace.

Substitute x =-1 and x = 0:

Range of this piece is [-5; -2)

Substitute x =0and x = 5:

Range of this piece is [3; 13)
Therefore the range of the following piecewise function is:

Look at the picture.
Answer:
given
n=9
a=1
d=3-1=2
Step-by-step explanation:
now , by formula,
sn = n/2(2a+(n-1)d)
= 9/2(2×1+(9-1)×2)
=9/2×18
=81
