Reasoning: unit rate : -9.95/1 you want to get to 3 months. So the fraction will look like ?/3. 1•3 = 3 so you have to multiply -9.95•3 to get how much is charged. The answer would be 29.85 and since there’s two different signs, it’ll be negative. -29.85. (Sorry if I’m late and all- hope this helps but if I’m wrong I’m sorry too)
Dylan and Tiffany each constructed a two-color spinner. Dylan spun his spinner 3 times and calculated that the
relative frequency of his spinner landing on blue (0.67) and on red (0.33). Tiffany spun her spinner 200 times
and calculated the relative probability of her spinner landing on blue (0.60) and on red (0.40).
How can Dylan's and Tiffany's calculations be used to evaluate the fairness of the two spinners?
Answers
Answer:
You can calculate the likeliness of the spinner landing on blue or red as the more spins you have the more accurate the results would be. In this case after 200 spins Tiffany calculated that the spinner landing on blue has a 60% chance while landing on red has a 40% chance. Therefore this might not be fair as there is a 60% chance landing on blue.

pls help me
Answers
Answer:
D is the right choice and no you cannot fit the pizza inside the box.
Step-by-step explanation:
D is the answer because to turn 2/3 into a decimal you would divide 2 by 3 and the answer you would get would be 0.66666666666...You would then add 12 to the answer and get 12.6666... Once you get this answer you would round it to the hundredths to get 12.67 but since that is not an option you could use D, 12.66 inches.

1. A group of students went to the movie theater.
Eighteen of the students bought popcorn.
The other 60% of the students bought candy.
How many students were in the group?
2.There are 21,000 fans at a football game cheering for the home team. The other 40% of the total people in attendance are cheering for the away team. How many people are in attendance at the game?
3.Ashley sees a book bag on sale in a store for $22. This is 20% off the original price. What was the original price of the book bag?
Answers
So the other 40% of students is 10 students. In total there are 28 students
2. 21,000 - 40% = 12,600
There are 33,600 people in attendance.
3. $26.40 is the original price
NUMBER 1
If 18 people is 40% that means the we need to start taking 40% off of numbers
40% of 20 is 12
40% of 25 is 15
40% of 30 is 18
So the answer is 30
NUMBER 2
If 21,000 people is 60% that means 20% is 7,000 people and 7,000x5=35,000 so there is a total of 35,000 people at the game
NUMBER 3
You should start taking 20% off of numbers.
20% of 25 is 20 too low so we need to go higher
20% of 26 is 20.8 still too low so lets keep going
20% of 27 is 21.60 closer but too low
20% of 28 is 22.40 which is too high lets go back since 27 is too low and 28 is too high lets start in between
20% of 27.5 is 22.00
So the answer is $27.5.
Name a combination of coins that is 130% of the value of a dollar.
Answers
Answer:
5 quarters, 1 nickel
Step-by-step explanation:
A combination of coins which is equivalent to 130% of a dollar is equal to 8 quarters,2 dimes and 2 nickels.
What are percentages?A percentage is a number or ratio that can be expressed as a fraction of 100. If we have to calculate the percent of a number, divide the number by the whole and multiply by 100. Hence, the percentage means, a part per hundred. The word percent means per 100. It is represented by the symbol “%”
Given: A dollar and to find its 130% equivalent in the form of coins.
A nickel is worth 5 cents
A dime is worth 10 cents
A quarter is worth 25 cents
Now a dollar is equivalent to 100 cents
Thus 130% of a dollar is equivalent to
130/100 ×100 +100 =230 cents
Therefore a combination of 8 quarters which is equal to 200 cents and 2 dimes and 2 nickel is equal to 230 cents as
8×25+2×10+2×5=230 cents.
Hence, A combination of coins which is equivalent to 130% of a dollar is equal to 8 quarters,2 dimes and 2 nickels.

Im not sure what to do here D:
Answers
Answer:
A and C
Step-by-step explanation:
Step 1: Replace x with 2.5 and see if it makes the equation correct.
A. |2 1/2 + x = 5| Since 2 and 1/2 is also written as 2.5, and 2.5+2.5=5, the solution makes this equation true.
B. |25x = 63| 25 x 2.5 equals 62.5, which does not make this equation true because 63 ≠ 62.5
C. |6.75x + 4.25x = 27.5| I Rewrite this equation as
(6.75 x 2.5) + (4.25 x 2.5) which can simplify to 16.875 + 10.625 and it does in fact equal 27.5, so this solution does make the equation true.
Step 2: Eliminate the equation(s) that aren't true, and then answer.
A and C are correct.

Using a directrix of y = −2 and a focus of (2, 6), what quadratic function is created?
here are the answers given
\/
f(x) = −one eighth (x − 2)2 − 2
f(x) = one sixteenth (x − 2)2 + 2
f(x) = one eighth (x − 2)2 − 2
f(x) = −one sixteenth (x + 2)2 − 2
Answers
Answer:
f(x)=1/16(x-2)^2+2
Step-by-step explanation:
The Equation can be written like this:
f(x) = 1/(4p)(x -h)^2 +(k-p)
where (h, k) is the focus, and p is half the distance between focus and directrix. Here, (h, k) = (2, 6) and p=(6-(-2))/2 = 4. So the equation is ...
f(x) = 1/16(x -2)^2 +2
