Answer 1

Answer:

y=5/2x-16

Step-by-step explanation:

First, we want to find the slope of the original line.

m= -4+8/-1-9

m= 4/-10

m= -2/5

Because we want the perpendicular bisector, we will need the slope to be the opposite reciprocal. Therefore, our slope is

m=5/2

Now, we want to find the midpoint of the line.

9-1/2

8/2=4

-8-4/2

-12/2= -6

So, the midpoint is (4,-6)

Using the information we have, we now can find b.

-6=5/2(4)+b

-6=10+b

-16=b

That gives us our equation

y=5/2x-16

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?

Answers

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

To find what she makes per hour, divide the amount she made by the time she spent. 67.50/9= 7.5 she makes 7.50 per hour. Then if she were to work for 5 hours a day, 7.5(5)=37.5. She makes 37.50 per day and multiply that by 6. She would make 225

A set of 5 consecutive integers sums to 10. What are the integers?

Answers

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.

Answer:

Hope you got it....

Step-by-step explanation:

1=tan(22∘+23∘)

1=tan22∘+tan23∘1−tan22∘tan23∘

1−tan22∘tan23∘=tan22∘+tan23∘

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

Answers

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

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?

Answers

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

3х - 4y ≤ -20 helppppp

Answers

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:

Find the values of x and z

Answers

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 = 6

Step-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 = 6

For z:

Because the 92° angle and z make a vertical angle, 92° = z°

The roots of $y^2 + 5y - 11 = 0$ are $a$ and $b$. Find $(a + 3)(b + 3).$

Answers

Since a and b are roots of y² + 5y - 11, we have

y² + 5y - 11 = (y - a) (y - b)

and expanding the right side gives

y² + 5y - 11 = y² - (a + b) y + ab

so that

a + b = -5

ab = -11

Now,

(a + 3) (b + 3) = ab + 3 (a + b) + 9

(a + 3) (b + 3) = -11 + 3 (-5) + 9

(a + 3) (b + 3) = -17

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.

Answers

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.

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 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.
