Answer:
Unit rate is 3.7 if that’s what you are asking for, you were not very specific.
Step-by-step explanation:
Answer:
10%
Step-by-step explanation:
20%=20/100=0.20
75$x.0.20=15$
The price when she received a 20% discount was:
75$-15$=60$
Then, the web site applied a 10% service fee to the discounted price, so you have:
10/100=0.10
75$x0.10=7.5$
60$+7.5$=67.5$
So, if 75$ is the 100% of the price, what percentage represents 67.5$?
75$--------100%
67.5$------x
x=67.5 x 100/75
x=90%
Then,
100%-90%=10%
Hello from MrBillDoesMath!
Answer: The relationship is linear. The equation is y = 2x + 19
Discussion:
When x changes from -7 to -5 ( and increment of of +2), y changes from 5 to 9 ( an increment of +4). When x changes from 5 to -3 (an increment of +2) , y changes from 9 to 13 (an increment of +4)... and so on.....
So far, when x changes by 2, y changes by 4. This means the data falls on a line (so is linear). In fact,
(change in y) / (change in x) = 4/2 = 2 = slope of line.
so y = 2x + b. As the line passes through the point ( -7, 5)
5 = 2 (-7) + b or
5 = -14 + b or ( adding 14 to both sides)
5 + 14 = 19 = b.
Hence the equitation the line is y = 2x + 19
Thank you,

The first thing we are going to assume for this case is that the tree and the post are located in the same place.
From that place, both cast a shadow in the same direction.
We then have two similar triangles.
Therefore, we have the following relationship:
From here, we clear the value of x.
We have then:

Answer:
the tree is 30 feet tall
Possible unit is m³
<u>Step-by-step explanation:</u>
- The possible unit for volume of a cone is m³
- Volume of a cone = Base area × Height
- Here unit for volume will be square units and that of height will be in units. Together, they form cubic units.
- In the given options, the only unit that is in cubic form is m³
