Answer:
There were 120 questions on the test.
Step-by-step explanation:
It is given that:
Number of questions answered = 54
Grade percent = 45%
Let,
x be the total number of questions
45% of x = 54
[tex]\frac{45}{100}x=54\\0.45x = 54[/tex]
Dividing both sides by 0.45
[tex]\frac{0.45x}{0.45}=\frac{54}{0.45}\\x=120[/tex]
Therefore,
There were 120 questions on the test.
If a line passes through (6,4) and (12,7), what is the slope? I really need help and if you can please explain how you got the asnwer
Answer:
0.5 OR 1/2
Step-by-step explanation:
Since the two points are (6,4) and (12,7) you would find the distance in x and y.
Slope = change in y/ change in x
Change in y: the y coordinates are 4 and 7, so 4 + 3 = 7. +3 is the change.
Change in x: the x coordinates are 6 and 12, so 6 + 6 = 12. +6 is the change.
Slope = 3/6 = 1/2 = 0.5 = 50%
Hope this helps :D

Find the zeros of 6x^2-27x
Answer:
x = 0, 9/2
Step-by-step explanation:
6x^2 - 27x = 0 (original)
3x(2x - 9) = 0 (factor out GCF of 3x)
|
v
(solve each factor (3x and 2x - 9) for x)
3x = 0
x = 0
2x - 9 = 0
2x = 9
x = 9/2

There are 635,000 residents in Jones County and 12.8% are under the age of 5. Approximately how many residents are under the age of 5?
Answer: 81280
Step-by-step explanation:
From the question, we are informed that there are 635,000 residents in Jones County and 12.8% are under the age of 5.
The number of residents that are under the age of 5 will be calculated as:
= 12.8% × 635000
= 0.128 × 635000
= 81280
The price of gas was $2.49 last month. This month, gas costs $2.79. What is
the percent increase?
Answer:
12%
Step-by-step explanation:
2.79 - 2.49 = $0.30
0.30 / 2.49 = 0.12 = 12% (decimal changes to percent)
You can check your work by doing original cost times the decimal of the percent increase. $2.49 * 0.12 = $0.30. Add this to original -> 0.30 + 2.49 = $2.79.

Sample Response: To find the image after a reflection over the x-axis, I would negate the y-coordinate. To find the image after a reflection over the y-axis, I would negate the x-coordinate. So, reflecting the point (5, 2) over the x- and y-axis, I would get (–5, –2).
Which did you include in your response? Check all that apply.
Negate the y-coordinate.
Negate the x-coordinate.
Get the point (–5, –2).
