X= the number
x-.20x=20
.80x=20
x= 20/.80
x=25
Answer:
c.
Step-by-step explanation:
Answer:
After 4 months
Step-by-step explanation:
The cost at both the programs consists of a "fixed cost" (reg fee) & "variable cost" ( per month fee).
Let number of months be "x"
<u>Yo-Yoga:</u>
35 fixed
90 per month
So equation would be: 35 + 90x
<u>Essence Yoga:</u>
75 fixed
80 per month
So equation would be: 75 + 80x
To find number of month when cost would be same, we equate both equations and solve for x:
35 + 90x = 75 + 80x
10x = 40
x = 40/10
x = 4
hence, after 4 months, both cost would be same
Answer: 56in³
Step-by-step explanation:
Let the volume of solid B de denoted as x. Based on the information given in the question, we can solve further by:
1/2 = 28/x
Cross multiply
1 × x = 2 × 28
x = 56
Therefore, the volume of solid is 56in³.
Answer:
0
Step-by-step explanation:
The question lacks the graph to be able to solve it, I was doing a little research and I could find the graph which I will attach:
Already with the figure we can solve the question.
We have that the average exchange rate in this case would only take the normal slope between those 2 lines
. Furthermore we know that the slope (m) is given by:
m = (y2-y1) / (x2 - x1)
From the graph we have to:
y2 = 0
y1 = 0
x2 = 5
x1 = 3
we replace:
m = (0-0) / (5 - 3)
m = 0
Therefore the average rate is 0.
