To pass her test, Tori needs to answer at least 65% of the questions correct. If there were 60
questions and she got 42 correct, did she pass? All work MUST be shown to justify your
answer.
Answers
2) .65 • 60 = 37.2 questions need to be right
3) since she got 42 correct, that is greater than 37.2, so she passed.
OR
1) 42/60 = 0.7
2) 0.7 to a percent = 70%
3) since she got a 70% on the test, she passed.
Step-by-step explanation:
To obtain score of 80% on entire exam means the student have to answer
(80/100)×80 = 64 correct answers
Student have already answered 75% of the first 60 questions correctly meaning
(75/100)×60=45 correct answers from first 60 questions
Remaining correct answers s/he have to answer
64-45=19
So from remaining 20 questions s/he have to answer 19 correct questions that is
20 × (x/100) = 19
x = 19 ×(100/20)
x = 95%

Answers
Answer:
It should be D, [tex]x^4 - 2x^3 + 7x^2 -12x - 4[/tex]
Step-by-step explanation:
Since, the equation given in the question is the factored form of the equation D. It can be solved using FOIL (First Outside Inside Last):
x * x³ = [tex]x^{4[/tex]
x * 7x = 7x²
x * 2 = 2x
-2 * x³ = -2x³
-2 * 7x = -14x
-2 * 2 = -4
This all would add up to ⇒ [tex]x^{4}[/tex] - 2x³ + 7x² + (-14x + 2x) -4
Simplifying the parenthesis further would give the option D as the answer.

Answer: 69 cents
Step-by-step explanation:
First you find the area of the circle (A = radius squared * pi) then you multiple the are by 5.5. That will give you the total volume of the can then to find what profit from the can you would multiple the volume by .01 to get .69.
Answer:
Rounded to nearest hundred
Here we will tell you what 69 is rounded to the nearest hundred and also show you what rules we used to get to the answer.
Remember, we did not necessarily round up or down, but to the hundred that is nearest to 69.
First, 69 rounded to the nearest hundred is:
100
When rounding to the nearest hundred, like we did with 69 above, we use the following rules:
A) We round the number up to the nearest hundred if the last two digits in the number are 50 or above.
B) We round the number down to the nearest hundred if the last two digits in the number are 49 or below.
C) If the last two digits are 00, then we do not have to do any rounding, because it is already to the hundred.
SO IT IS 100
But if it was nearest tenth that would be 70

A candle burns down at the rate of 0.5 inches per hour. The original height of the candle was 6 inches.
Part A: Write a list of 6 ordered pairs to show the height of the candle in inches (y) as a function of time in hours (x) from the first hour after it started burning. For example, the point (0, 6) would represent a height of 6 inches after 0 hours. Explain how you obtained the ordered pairs. (5 points)
Part B: Is this relation a function? Justify your answer using the list of ordered pairs you created in Part A. (2 points)

Answer:
A. (0, 6), (1, 5.5), (2, 5), (3, 4.5), (4, 4), (5, 3.5)
B. is a function
C. is a function
Step-by-step explanation:
Both relations are functions.
A relation is NOT a function if the same input value maps to two different output values. Virtually any relation involving time as an input will be single-valued: a measure can only have one value at any given time (ignoring quantum physics).
__
A: If height decreases 1/2 inch per hour, then some ordered pairs could be ...
(hours, inches) = (0, 6), (1, 5.5), (2, 5), (3, 4.5), (4, 4), (5, 3.5)
For each additional hour, 0.5 inches was subtracted from height.
__
B: There is only one output for each input, so the relation is a function.
__
C: Yes, the relation is still a function. There is still only one output value for each input value.

What is the volume of the cylinder and i need how you got the answer plz. Thank you
Answers
Answer:
471.24 inches is the volume of the cylinder.
Basically, since the diameter of the cylinder is 10 inches the radius will be 5 inches.
The formula to figure out the volume of a cylinder is V=πr2h.
So using that formula the volume of the cylinder is 471.24 inches.
V = Pi*R^2*H
V = Pi*5^2*6
V = Pi*25*6
V = Pi*150

Answer:

another way you can get these answers is by cross multiplying. In order to do that you need to identify the percent, the whole (of), and the part (is). In identifying the whole and the part, look for the word is, and the word of. The number that is associated with is either the part or the whole. (There is 6 out of 80, what is the percentage?) always set the percentage out of a hundred.
So from there we set up the proportion:
ONE
(we don't know the part in any of them)
X/80=35/100 (cross multiply by putting the numbers on top of each other for the fractions)
TWO
X/65=10/100
THREE
X/50=60/100

Part B: What are the initial value and slope of the graph and what do they represent?
Answers
Step-by-step explanation:The slope of AB and BC are the same.
The initial value is 60 m and the slope is 40 m/min.
Step-by-step explanation:
The graph shows the depth, y, in meters, of a shark from the surface of an ocean for a certain amount of time, x, in minutes.
See the graph attached.
Part A : If we consider two right triangles one Δ ABD and Δ BCE, where D(2,100) and E(1,60) points.
Now, those two triangles are similar and hence the slope of line segment AB will be .
Again, the slope of the line segment BC will be
Hence, and the slope of AB and BC are the same. (Answer)
Part B : From the graph, it is clear that the initial value of the graph is 60 m and it represents that initial position of the shark i.e. at t = 0 min, the shark was at a depth of 60 m from the water surface.
The slope of the graph is 40 means the rate of change of distance from the Ocean surface of the shark with respect to time in minutes will be 40 m per min. (Answer)
