Step-by-step explanation: Answer: around 64 minutes
We need to first set the two equal to each other.
We can model the first part using the slope intercept form.
y=.17x+15
We are trying to find the amount of minutes or x she can spend. We solve for x by using inverse operations.
However, the question states that she has already paid the flat fee of 15 dollars, so we are only doing .17x=10.92 (inverse operations for x)
X=64.23 minutes or around that.
You use > for greater than and < for less then
-4 < x < 6
Answer:
1. a^3/6 (15)^{1/2}
2.
a. a = 12 cm
b. V = 384 cm^3
Step-by-step explanation:
1. The volume of rectangular pyramid is given by:
b: base area = a^2
h: height
c: side edge = 2a
"h" can be calculated by using the Pitagora's theorem:
The, the volume is:
2.
a. The side base is calculated by using the Pitagora's theorem again:
b. The volume is given by:
N is less than or equal to -8
