H=height
y=number of years.
we have the next expresion:
h(y)=my+b
m=the slope of the line, in this case, the slope is equal to "18"; (18 cm/ year).
b=the initial heigth, in this case, the initial heigth is equal to "5" (5 cm).
Therefore, our expression will be:
h(y)=18y +5
answer: h(y)=18y+5
100+30=130
100+40=140
online price is 130% or original
superstore price is 140% or original
the difference bewteen them is 140-130=10% of the original price
A. 1.3 times 160=208=online
1.4 times 160=224=superstore
B. difference is 224-208=16=10% of 160
it is 10% of the original price
A. online=$208
superstore=$224
B. $16, this is 10% of the original price
The pressure is 39 Pa if the volume is expanded to 168L and the pressure, P, of a gas varies inversely with its volume, V.
<h3>What is a proportional relationship?</h3>
It is defined as the relationship between two variables when the first variable increases, the second variable also increases according to the constant factor.
We have:
The pressure, P, of a gas varies inversely with its volume, V.
P ∝ 1/V
P = k/V
k is the constant.
If P = 126 Pa and V = 52 L
126 = k/52
k = 6552
P = 6552/V
Plug V = 168 L
P = 6552/168 = 39 Pa
Thus, the pressure is 39 Pa if the volume is expanded to 168L and the pressure, P, of a gas varies inversely with its volume, V.

First of all, you have to rank the numbers from the lowest to the hightest. I let you to do it.
There are 10 numbers.
So, 0.25*10 = 2.5.
In that case, the 1st quartile would be the third number "17".
Hope this helps !
