Answer:
Explanation on ratio and rates.
Step-by-step explanation:
So rates are when you compare two things. For example let's say there are 12 boys and 10 girls. The ratio would be 12:10 or 6:5. Rates is also comparing two things but in fraction format. For example if you drive 30 miles in 3 hours the rate would be 30/3. 10 miles per hour is a unit rate since it is 1 hour, 10/1. I hope this helps you, have a good day.

1b. b. At midnight the temperature is -7°C. At midday the temperature is 4°C. By how much did the temperature rise? * 1 point Your answer
Answer:
[tex]Rise = 11^\circ C[/tex]
Step-by-step explanation:
Given
[tex]Midnight \to -7^\circ C[/tex]
[tex]Midday \to 4^\circ C[/tex]
Required
The temperature rise
This is the difference between the final and the initial temperature
[tex]Rise = Midday - Midnight[/tex]
[tex]Rise = 4^\circ C - -7^\circ C[/tex]
[tex]Rise = 4^\circ C +7^\circ C[/tex]
[tex]Rise = 11^\circ C[/tex]

Please help what does B equal and C equal :)
Answer:
m∠b=m∠c=61°
Step-by-step explanation:
The 119° angle and ∠b/∠c are supplementary angles. ∠b and ∠c are congruent because they are vertical angles and they are also both supplementary to the 119° angle. I will use b to find c.
[tex]b+119=180[/tex]
[tex]b=61[/tex]
Since b and c are equal, c=61 too.

The two bases of a trapezoid measure 14 inches and 10 inches respectively. The trapezoid's height is 8 inches. What is the area of the trapezoid?
Answer:
A.O.T=1/2×height(sum of bases)
Step-by-step explanation:
A.O.T=1/2×8(14+10)

96
Step-by-step explanation:
What is the value of y?
Answer and Step-by-step explanation:
We are given a triangle and are asked to solve for the value of y.
We know that the angles in a triangle add up to 180 degrees. So let's add all of the angles together and equal it to 180.
2y + y + 10 + 50 = 180
Combine like terms.
3y + 60 = 180
Now subtract each side by 60.
3y = 120
Finally, divide each side by 3.
y = 40
We get the value of y to be 40.

what else would you need to measure the area of something
The simplest (and most commonly used) area calculations are for squares and rectangles. To find the area of a rectangle, multiply its height by its width. For a square you only need to find the length of one of the sides (as each side is the same length) and then multiply this by itself to find the area.
A parabola can be drawn given a focus of (1,3) and a directrix of x = -7. What
can be said about the parabola?
The parabola has a vertex at (
), has a p-value of
and it
PLEASE HELP
Answer:
Below.
Step-by-step explanation:
The parabola will open to the right and will be symmetrical about y = 3.
The vertex is halfway between x = 1 and x = -7 making it at (-3, 3).
The p value is the distance between the vertex and the focus - here it is 1 - -3
= 4.
Answer:
The parabola has a vertex at (-3, -6), has a p-value of 4 and it opens right.

Many fundraisers ask for donations using email and text messages. A paper describes an experiment to investigate whether the proportion of people who make a donation when asked for a donation by email is different from the proportion of people who make a donation when asked for a donation in a text message. In this experiment, 1.8% of those who received and opened an email request for a donation and 7.9% of those who received a text message asking for a donation actually made a donation. Assume that the people who received these requests were randomly assigned to one of the two groups (email or text message) and suppose that the given percentages are based on sample sizes of 2,000 (the actual sample sizes in the experiment were much larger). (Let p1 be the proportion who make a donation after receiving an email, and p2 be the proportion who make a donation after receiving a text message.)
The study described is an experiment with two treatments. What are the two treatments?
a. fundraisers
b. donations using text message
c. charitable giving
d. donations using email
e. deadlines
Answer:
b. donations using text message
d. donations using email
Step-by-step explanation:
From the question, it is clear that the people who received these requests were assigned to two groups and these 2 were assigned treatments of if they make donations after either receiving email or text messages after which their respective proportions p1 and p2 are determined.

7x+10=36
y=2x+9
x=
y=
Answer:
x=26/7
y=115/7
Step-by-step explanation:
7x+10=36>>subtract 10 from 10 and 36 you get 7x=26>>>divide both sides by 7>>>>x=26/7
To find find y you substitute the x for 26/7>>2(26/7)+9=115/7

Use the formula 2x + 3y = 6 to find y when x=0
Answer: 4/3
Step-by-step explanation:
You would find this answer because if x is 0 then it is just 2 then when you multiply 3 x 4/3 you get 4 then when you add that by two you get 6
Hopes this helps
Answer: y=2
Step-by-step explanation: where there is x you put 0
2(0)+3y=6
0+3y=6
3y=6
Then divide both sides with 3
(3y/3)=(6/3)
Y=2

An English teacher needs to pick 9 books to put on his reading list for the next school year, and he needs to plan the order in which they should be read. He has narrowed down his choices to 13 novels, 17 plays, and 13 nonfiction books. If he wants to include an equal number of novels, plays, and nonfiction books, how many different reading schedules are possible
Answer:
Different schedule Possible = 55,621,280
Step-by-step explanation:
Given - An English teacher needs to pick 9 books to put on his reading list for the next school year, and he needs to plan the order in which they should be read. He has narrowed down his choices to 13 novels, 17 plays, and 13 nonfiction books.
To find - If he wants to include an equal number of novels, plays, and nonfiction books, how many different reading schedules are possible ?
Formula used -
Number of combinations of n things taking r at a time : [tex]^{n}C_{r}[/tex] = [tex]\frac{n!}{r! (n-r)!}[/tex]
Proof -
Given that, An English teacher needs to pick 9 books and wants to include equal number of novels, plays, and nonfiction books
i.e. he will Choose
3 books from Novels
3 books from Plays
3 books from Non-fiction books
Now,
Given that,
Total number of novel = 13
Total number of plays = 17
Total number of non-fiction books = 13
So,
Different schedule Possible = [tex]^{13}C_{3}* ^{17}C_{3}*^{13}C_{3}[/tex]
= [tex]\frac{13!}{3! (13-3)!}* \frac{17!}{3! (17-3)!}* \frac{13!}{3! (13-3)!}[/tex]
= [tex]\frac{13!}{3! (10)!}* \frac{17!}{3! (14)!}* \frac{13!}{3! (10)!}[/tex]
= [tex]\frac{13(12)(11)10!}{3! (10)!}* \frac{17(16)(15)14!}{3! (14)!}* \frac{13(12)(11)10!}{3! (10)!}[/tex]
= [tex]\frac{13(12)(11)}{3(2)(1)}* \frac{17(16)(15)}{3(2)(1)}* \frac{13(12)(11)}{3(2)(1)}[/tex]
= [tex]{13(2)(11)}*{17(8)(5)}* {13(2)(11)}[/tex]
= 55,621,280
⇒Different schedule Possible = 55,621,280
Claire has quarters and nickels in her purse. The total value of the coins is $2.65. Which equation can be used to find x, the number of quarters in Claire’s purse?
Coins in Claire’s Purse

Nickels
2x + 4
Quarters

5 (2 x + 4) + 25 x = 2.65
0.05 (2 x + 4) + 0.25 x = 2.65
0.5 (2 x + 4) + 0.25 x = 2.65
(2 x + 4) + x = 2.65
Answer:
0.05(2x +4) +0.25x =2.65
Step-by-step explanation:
The decimals are in the right places. A. would have been correct but it would have had to be 265 instead of 2.65. They put the decimals in the incorrect place.
Answer:
0.05(2x +4) +0.25x =2.65 or b
