Answer: Her end score would be 200 points.
Step-by-step explanation:
Add everything together like so, 200+-400+100+-600+700+200 and that equals 200
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.
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%
20 points :) Select the favorable outcomes for rolling doubles.
(1-1) (2-2) (3-3) (4-4) (5-5) (6-6)
(5-1) (5-2) (5-3) (5-4) (5-5) (5-6)
(1-1) (1-2) (1-3) (2-1) (2-2) (3-1)
(1-3) (2-3) (3-1) (3-2) (3-4) (3-5) (3-6) (4-3) (5-3) (6-3)
Answer: A. (1-1), (2-2), (3-3), (4-4), (5-5), (6-6)
Step-by-step explanation:
Doubles are any pair of numbers where the outcomes are the same. There are 36 possible outcomes, and 6 of them are doubles since they have the same numbers. For example, (1-1), also known as snake eyes, are doubles since a 1 is rolled on each die. Therefore, the answer is A.
Answer:
(1-1), (2-2), (3-3), (4-4), (5-5), (6-6)
Step-by-step explanation:
(1-1), (2-2), (3-3), (4-4), (5-5), (6-6)
Find the LCM of 6 and 15.
A) 6
B) 15
C) 30
D) 90
Answer:
30
Step-by-step explanation:
the answer is 30 because if you count by 6 it would go 6,12,18,24,30,36,42 and if you go by 15 it would be 15,30,45,60,75,90..... and the only number that you see twice is 30 so the answer would be 30. Hope this helped...

MATH SMARTIES I WILL GIVE BRAINLIEST PLEASE GIVE EXPLINATION THE HWERK IS PERCENTS
Answer:
a. 28
b. 6.5
c. 30
Step-by-step explanation:
1% = 80÷100
35% = 0.8×35
1% = 0.65
0.65 × 10 = 6.5
1% = 0.5
60% = 0.5×60
Answer:
28
6.5
30
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

Step-by-step explanation:
What is the volume of the cylinder and i need how you got the answer plz. Thank you
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.
Find the perimeter and the area of the polygon with the given vertices.
T (2,7), U (2,9), V (5,9), W (5,7)
The perimeter is __ units.
The area is ___ square units.
Answer:
Step-by-step explanation:
TU , UV , VW, TW are the sides
As points T and U have same x-coordinate, length of TU will be given by the difference of y-coordinate
TU = 9 - 7 = 2 units
As points U and V have same y-coordinate, length of UV will be given by the difference of x-coordinate
UV = 5 - 2 = 3 units
As points V and W have same x-coordinate, length of VW will be given by the difference of y-coordinate
VW = 9 -7 = 2 units
As points W and T have same y-coordinate, length of WT will be given by the difference of x-coordinate
WT = 5 - 2 = 3 units
TU = VW = 2 units
UV = WT = 3 units
So, TUVW is a rectangle
Area = length *width = 3* 2 = 6 square units
Perimeter = 3 + 2 + 3 + 2 = 10 units

What is the exact circumference of a circle that has a radius of 10 cm?
Answer:
C = 20π cm
Step-by-step explanation:
If you want the "exact circumference," use π instead of the usual approximation 3.14 or 3.14159.
Here the circumference is C = 2π(10 cm), or C = 20π cm.

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)
Part C: If the rate at which the candle burnt was 0.3 inches per hour instead of 0.5 inches per hour, will the relation continue to be a function? Explain your answer using input and output values. (3 points)
9514 1404 393
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.

Step-by-step explanation:
To go down the line, you need to do the 15 x 15 x 15 x 15 (15^4), in which equals 50,625. Then, 50,625 - 10 which equals 50,615. Next, 50,615 + 36 which equals 50,651. Finally, you would need to do 50,651 ÷ 10. Making it *5065.1*

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

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.
For each number, name its opposite.
a. -5
b. 28
C. -10.4
d. 0.875
e. O
f. -8,003

Find the area of the shaded region.
Answer:
75m2
Step-by-step explanation:
Usually, we would subtract the area of a smaller inner shape from the area of a larger outer shape in order to find the area of the shaded region.
The area of the shaded region is the difference between the areas of the rectangle and the square. The dimensions of the rectangle are 6 by 8 and so the area is 6 times 8, that is 48 square units. Each side of the square measures 2 units and so the area is 2 times 2, that is 4 square units.
