Heritage Middle School has 150 students. Two out of three students in Mrs. Masons class prefer gel toothpaste. use this rate to predict how many students inthe entire Middle School prefer gel toothpaste.
Answer:
100 bc 150/3 = 50x2=100 this equation vary on the percent bc if it was 3/3 then u would devide by 3 then times 3 get it?
Answer:
100 students.
Step-by-step explanation:
First because it says "..2 out of 3" you have 2 boxes (i'm using a tape diagram) for the students that prefer gel toothpaste and 1 box for the others/don't prefer gel toothpaste students. Since there are 150 students in the school in total you will divide the number of students (150) by the 3 boxes and get 50. Each box will be filled with 50. Students that prefer gel toothpaste : 50 x 2 = 100 (students) Students that don't prefer gel toothpaste : 50 x 1 = 50 (students).
Hope this made sense somehow lol, i'm not very good at explaining.
We may conclude that (a) events A and B are independent. (b) events A and B are mutually exclusive. (c) either A or B always occurs. (d) events A and B are complementary. (e) none of the above is correct.
Answer:
The answer is below
Step-by-step explanation:
The question is not complete. But I would show you how to solve the problem.
Two events A and B are said to be independent if the occurrence of event A does not affect the occurrence of event B and vice versa. P(A and B) = P(A) * P(B).
Two events A and B are said to be mutually exclusive if event A and event B cannot occur at the same time. P(A and B) = 0.
Two events A and B are said to be complementary when event A occurs if and only if event B does not occur and vice versa.

Find the equation of the line?
Answer:
Y=-1/4x-6
Step-by-step explanation:
Prove that tan22° + tan23° + tan22°. tan23° = 1
Answer:
Hope you got it....
Step-by-step explanation:
1=tan45∘
1=tan(22∘+23∘)
1=tan22∘+tan23∘1−tan22∘tan23∘
1−tan22∘tan23∘=tan22∘+tan23∘
1=tan22∘+tan23∘+tan22∘tan23∘
It will be the same for any two angles that add up to 45∘.
Answer:
ooo....
Step-by-step explanation:
22° + 23° = 45°
taking tan on both side
or,tan(22° + 23°)=tan45°
or,(tan22° + tan23°)/(1-tan22°. tan23°)=1
or,tan22° + tan23° =1- tan22°. tan23°
or,tan22° + tan23° + tan22°. tan23° = 1

A bookshop has an offer. "Buy one book and get one free!" Ria gets 8 books from the shop with that offer. The normal price of each book is £6.99. How much does Ria spend?
Answer: £27.96
Step-by-step explanation:
Since the bookshop has an offer. "Buy one book and get one free!" and we are told that Ria gets 8 books from the shop with that offer. This simply means that Ria bought 4 books and also got 4 free.
Since the normal price of each book is £6.99 and Ria bought 4 books, the amount Ria spend will be:
=£6.99 × 4
= £27.96

Which equation represents this problem? The time it takes Tomás to bike to the community center is 2 minutes less than half the time it takes him to bike to the city park. It takes Tomás 18 minutes to bike to the community center. Let p = the time it takes Tomás to bike to the park.
A. 2p+12=18
B.12p+2=18
C.2p–12=18
D.12p–2=18
Answer:
The equation that represents this problem is [tex]\frac{1}{2}[/tex] p - 2 = 18 ⇒ D
Step-by-step explanation:
Let us solve the question
∵ p is the time it takes Tomás to bike to the park
∵ The time it takes Tomás to bike to the community center is 2 minutes
less than half the time it takes him to bike to the city park
→ That means multiply p by [tex]\frac{1}{2}[/tex] , then subtract 2 from it
∴ The time to the community center = [tex]\frac{1}{2}[/tex] (p) - 2
∴ The time to the community center = [tex]\frac{1}{2}[/tex] p - 2
∵ It takes Tomás 18 minutes to bike to the community center
→ Equate The time to the community center by 18
∴ [tex]\frac{1}{2}[/tex] p - 2 = 18
∴ The equation that represents this problem is [tex]\frac{1}{2}[/tex] p - 2 = 18
Tammy takes a taxi home from the airport. The taxi fare is $2.10 per mile, and she gives the driver a tip of $5. Tammy pays a total of $49.10. What is the distance (in miles) between Tammy's home and the airport?
Answer:
21
Step-by-step explanation:

Rachel earns $67.50 for working 9 hours at the dairy farm. How much does Rachel make per hour? How much would Rachel make if she works 5 hours a day for 6 days?
Answer:
$225
Step-by-step explanation:
Frist, we need to figure out how much Rachel makes per hour. For 9 hours of work, she makes $67.50
67.5 / 9 = 7.5
Rachel makes $7.50 per hour
Now we can add up all the hours she worked.
5 hours a day for 6 days
5 x 6 = 30
She worked 30 hours at a rate of $7.50 per hour
7.5 x 30 = 225
She earned $225

Your answer
Answer:
∠ 6 = 28°
Step-by-step explanation:
152° and ∠ 5 are corresponding angles and are congruent, then
∠ = 152°
∠ 5 and ∠ 6 are adjacent angles and are supplementary, thus
∠ 6 = 180° - 152° = 28°
Find the values of x and z
Answer:
z = 92 degrees
x = 6
Step-by-step explanation:
z and the angle that measures 92 degrees are vertical angles which means they are congruent. So, z = 92 degrees.
The total measure of all these angles is 360 degrees. Subtract 92*2 from 360 and divide the answer by 2. You get 88.
88 = 9x + 34
Solve for x.
x = 6
Answer:
z = 92°x = 6Step-by-step explanation:
For x:
Write and algebraic equation: 92 + (9x + 34) = 180Combine like terms: 126 + 9x = 180Subtract 126 from each side, so it now looks like this: 9x = 54Divide each side by 9 to cancel out the 9 next to x. It should now look like this: x = 6For z:
Because the 92° angle and z make a vertical angle, 92° = z°I hope this helps!

A set of 5 consecutive integers sums to 10. What are the integers?
Answer:
Let x be the smallest integer (the first integer)
1st: x, 2nd: x + 1, 3rd: x + 2, 4th: x + 3, 5th: x + 4
Hence,
x + x + 1 + x + 2 + x + 3 + x + 4 = 10
5x + 10 = 10
5x = 0
x = 0
Therefore, the answers are
0, 1, 2, 3, 4
Step-by-step explanation:
Integers include all positive integers, negative integers and 0.
0 is an integer but it is neither positive nor negative.

3х - 4y ≤ -20 helppppp
Answer:
I suppose that you want to find the region of solutions.
We start with the inequality:
3х - 4y ≤ -20
To solve this, will be easier to write this as a linear relationship, we can do this as follows:
3x - 4y ≤ -20
-4y ≤ -20 - 3x
y ≥ (-20 - 3x)/-4
(Notice that the "direction" of the sign changes, this is because we divided both sides by a negative number).
y ≥ 5 + (3/4)*x
Now we have the equation of a line, and we know that y will be equal or greater than the line, this means that we need to draw the line and shade all the area above the line, as shown in the graph below:

Choose two numbers from this list: 3, 4, 6, 12. Explain the difference between finding the greatest common factor and the least common multiple of the two numbers.
Answer:
Please check explanations for answer
Step-by-step explanation:
Let us choose 4 and 6
When we talk of the greatest common factor, we mean the highest number that is a factor of both numbers
The factors of 4 are 1,2,2 and 4
Factors of 6 are 1,2,3 and 6
So as we can see the only common factors to both are 1,2 but the highest here is 2
The least common multiple refers to the smallest number which divides 4 and 6 at the same time without leaving a remainder
Multiples of 4 are 4,8,12 , 16,20 •••••
multiples of 6 are 6,12,18,24
As we can see, the lowest common number to both is 12
