1/2 Kg of Cherries
Give both 2/5 and 1/10 a common denominator- 10
4/10 + 1/10 = 5/10 = 1/2
Amount of tax paid = 43-40 = 3
Tax rate = 3/40 = 0.75
0.75 x 100 = 7.5%
Tax rate = 7.5%
Answer:
8
Step-by-step explanation:
using
a= 6 c=10
Slope: rise over run, for any straight line. Example: y=mx + b
Constant of proportionality: a constant by which you multiply your independent variable (x) to get a specific value of the dependent variable (y). Example: y=kx.
The main difference here is that y=mx+b may or may not pass through the origin, whereas y=kx always passes through the origin.
Both k and m are "slopes," with k pertaining to direct variation y=kx, and m pertaining to slope of a line which may or may not pass through the origin.
In this limited sense, both k and x are slopes. k could be the slope of a straight line passing thru the origin, same as m, but m could not be the constant of proportionality if the line in question does not pass through the origin.
Answer:
9 x 3 = 27, 27 x 2 = 54
4 x 3 = 12, 12 x 2 = 24
9 x 4 = 36, 36 x 2 = 72
Add given areas:
54 + 24 + 72 = 150 cm^2 is your answer.
