Solve for u. -9–4u=-u

Answers

Answer:

u = -3

Step-by-step explanation:

-9 - 4u = -u

+4 = +4

Add 4u to both sides.

-9 = 3u

Divide both sides by 3

-9/3 = 3/3

-3 = u

Answer: The variable u is equal to -3 for this equation.

Step-by-step explanation:

To solve this variable equation, you will need to follow these steps:

Rewrite the equation, moving 9 to the other side, adding it on both sides, and simplify

-4u = -u + 9

After that, move u to the other side of the equation, also adding it on both sides and simplify

-3u = 9

Then divide both sides by -3, simplify it one last time and you will get your answer!

-3

Therefore, the answer to this equation would be equal to negative three or -3. Hope this helps!

The members of a school club are selling tickets for a fundraiser. The goal for the fundraiser is to earn $50.00 each day from ticket sales. The list below shows the percent of the goal reached each day.
On the first day, the members earned 90% of their daily goal.
On the second day, the members earned 6% more than their daily goal.
On the third day, the members earned 14% less than their daily goal.

Answers

Answer:

$151.00 was earned over the 3 days.

Step-by-step explanation:

First Day:

.90(50)

Second Day:

50 + .06(50)

Third Day:

50 - .14(50)

.9(50) + 50 + .06(50) + 50 - .14(50)

45 + 53 + 43

141

Answer:

They made 45 dollars the first day, 53 dollars the second day, and 43 dollars the third day. In total the made 141 dollars.

Step-by-step explanation:

For the first day you multiply the goal amount by the decimal or fraction that represents the percentage to get your answer. So it would be:

50 x 0.90 = 43

For the second day you do the same as above, but once you get the answer to that step, you add fifty to it. You can also do it all in one step. It would look like:

50 x 0.06 = 33 + 50 = 53

50 + (50 x 0.06) = 53

For the third day you would do the same as you did for the first day, then you would take that answer and subtract it from fifty. You can do this all in one step too. It should look like this:

50 x 0.14 = 750 - 7 = 43

50 - (50 x 0.14) = 43

Then to get your final answer, you would just add all of the days up like this:

45 + 53 + 43 = 141

So your answer would be 141 dollars, or $141.00

I hope this helped and will help you do similar problems in the future!

Answer:

$\frac{16}{27}$

Step-by-step explanation:

From the table, we notice that the total number of students is:

$3+10+8+6=27$

Then, along the second column of the table, we notice that the number of students who do not have a brother is:

$10+6=16$

So, the probability that a randomly chosen student does not have a brother is:

$\frac{\text{number of students who do not have a brother}}{\text{total number of students}}=\frac{16}{27}$

16 over 27 sorry if i’m wrong.

The stem-and-leaf plot displays data collected on the size of 15 classes at two different schools.

Mountain View School Seaside School
0 5, 8
9, 8, 2, 0 1 0, 1, 2, 5, 6, 8
8, 7, 6, 5, 5, 4, 4, 3, 1, 0 2 5, 5, 7, 7, 8
0 3 0, 6
Key: 2 | 1 | 0 means 12 for Mountain View and 10 for Seaside

Part A: Calculate the measures of center. Show all work. (2 points)

Part B: Calculate the measures of variability. Show all work. (1 point)

Part C: If you are interested in a smaller class size, which school is a better choice for you? Explain your reasoning. (1 point)

Answers

To calculate the measures of center, we need to find the mean and median for each school.

For Mountain View School:
Data: 0, 0, 0, 0, 1, 2, 3, 4, 4, 5, 5, 5, 5, 6, 7, 8, 8, 8, 9
Mean: (0 + 0 + 0 + 0 + 1 + 2 + 3 + 4 + 4 + 5 + 5 + 5 + 5 + 6 + 7 + 8 + 8 + 8 + 9) / 19
= 100 / 19
≈ 5.26

To find the median, we need to arrange the data in ascending order: 0, 0, 0, 0, 1, 2, 3, 4, 4, 5, 5, 5, 5, 6, 7, 8, 8, 8, 9.
The median is the middle value, which is the 10th value in this case.
Median: 5

For Seaside School:
Data: 0, 0, 0, 1, 1, 2, 2, 4, 5, 5, 5, 5, 6, 7, 7, 8, 8, 8, 9
Mean: (0 + 0 + 0 + 1 + 1 + 2 + 2 + 4 + 5 + 5 + 5 + 5 + 6 + 7 + 7 + 8 + 8 + 8 + 9) / 19
= 80 / 19
≈ 4.21

To find the median, we need to arrange the data in ascending order: 0, 0, 0, 1, 1, 2, 2, 4, 5, 5, 5, 5, 6, 7, 7, 8, 8, 8, 9.
The median is the middle value, which is the 10th value in this case.
Median: 5

Now let's calculate the measures of variability, specifically the range and interquartile range (IQR).

Range: The range is the difference between the largest and smallest values in the dataset.

For Mountain View School:
Range: 9 - 0 = 9

For Seaside School:
Range: 9 - 0 = 9

Interquartile Range (IQR): The IQR is the difference between the third quartile (Q3) and the first quartile (Q1) and measures the spread of the middle 50% of the data.

For Mountain View School:
Q1 = 3
Q3 = 7
IQR = Q3 - Q1 = 7 - 3 = 4

For Seaside School:
Q1 = 2
Q3 = 7
IQR = Q3 - Q1 = 7 - 2 = 5

To determine which school is a better choice for a smaller class size, we can consider both the mean and the median.

Both the mean and median for Mountain View School are higher than those for Seaside School. This suggests that, on average, the class sizes at Mountain View School are larger than those at Seaside School. Therefore, if you are interested in a smaller class size, Seaside School would be a better choice

Part A:

For Mountain View School:
- Median: The median class size is the middle value, which is 25.
- Mean: The mean class size is the sum of all the class sizes divided by the total number of classes, which is (29 + 28 + 28 + 27 + 25 + 24 + 24 + 23 + 21 + 20 + 19 + 18 + 15 + 13 + 10) / 15 = 21.27.

For Seaside School:
- Median: The median class size is the middle value, which is 20.
- Mean: The mean class size is the sum of all the class sizes divided by the total number of classes, which is (25 + 25 + 27 + 27 + 28 + 28 + 28 + 30 + 31 + 35 + 36 + 38 + 40 + 43 + 45) / 15 = 31.13.

Part B:

For Mountain View School:
- Range: The range is the difference between the largest and smallest values, which is 29 - 10 = 19.
- Interquartile Range (IQR): The IQR is the difference between the third quartile (Q3) and the first quartile (Q1). From the stem-and-leaf plot, we can see that Q1 is 20 and Q3 is 28. Therefore, the IQR is 28 - 20 = 8.

For Seaside School:
- Range: The range is the difference between the largest and smallest values, which is 45 - 25 = 20.
- Interquartile Range (IQR): The IQR is the difference between the third quartile (Q3) and the first quartile (Q1). From the stem-and-leaf plot, we can see that Q1 is 27 and Q3 is 38. Therefore, the IQR is 38 - 27 = 11.

Part C:

If you are interested in a smaller class size, Mountain View School is a better choice for you because it has a lower mean and median class size than Seaside School.

solve the equation for y: y + 7 = 5/4 (x + 16)

Answers

To solve the equation for y, we need to get y by itself on one side of the equation.

The first step is to get rid of the fraction on the right side of the equation by multiplying both sides by 4:

4y + 28 = x + 16

Then, we need to move the x term to the left side of the equation by subtracting x from both sides:

4y + 28 - x = 16

Then, we need to move the constant term 28 to the left side of the equation by subtracting 28 from both sides:

4y - x = -12

Finally, we have the equation in the form y = (1/4)x - 3, so the solution for y is y = (1/4)x - 3

It is important to note that in this solution we have used the distributive property and followed the order of operations to get to the final result, if you don't follow this steps you might get a different result.

STEPS FOR SOLVING LINEAR EQUATIONy+7=45(x+16)Use the distributive property to multiply 45 by x+16.y+7=45x+20Swap sides so that all variable terms are on the left hand side.45x+20=y+7Subtract 20 from both sides.45x=y+7−20Subtract 20 from 7 to get −13.45x=y−13Divide both sides of the equation by 45, which is the same as multiplying both sides by the reciprocal of the fraction.4545x=45y−13Dividing by 45 undoes the multiplication by 45.x=45y−13Divide y−13 by 45 by multiplying y−13 by the reciprocal of 45.x=54y−52SOLVE FOR Yy=45x+13

Mackey invested some money in an account paying 6% interest for one year. She invested $1000 more than this amount in an account paying 8.5%. How much did she invest in total if the total interest earned in the year was $737.50?

Answers

Step-by-step explanation:

Let's assume the amount Mackey initially invested in the 6% account is x dollars.

According to the given information, Mackey invested $1000 more than x in the 8.5% account, which means she invested (x + $1000) dollars in that account.

The total interest earned from the 6% account would be 0.06x dollars, and the total interest earned from the 8.5% account would be 0.085(x + $1000) dollars.

The total interest earned in the year is given as $737.50, so we can set up the equation:

0.06x + 0.085(x + $1000) = $737.50

Simplifying the equation:

0.06x + 0.085x + 0.085($1000) = $737.50

Combining like terms:

0.145x + $85 = $737.50

Subtracting $85 from both sides:

0.145x = $737.50 - $85

0.145x = $652.50

Dividing both sides by 0.145:

x = $652.50 / 0.145

x ≈ $4500

Therefore, Mackey initially invested approximately $4500 in the 6% account, and she invested $1000 more, which means she invested a total of $5500.

$4500

A cylindrical cake is made in a pan that has a diameter of 10
inches and a height of 2 inches. What is the total surface
area of the icing on the cake?

Answers

141.37 square inches

Answer:

about 141.4 square inches

Step-by-step explanation:

You want the area of icing on a cake that is 10 inches in diameter and 2 inches high.

Icing

The icing on a cake covers the lateral surface area and the area of the circular top. In terms of diameter, the sum of those areas is ...

icing area = πdh +(π/4)d² = πd(h +d/4)

icing area = π(10 in)(2 in + (10 in)/4) = π(10 in)(4.5 in)

icing area = 45π in² ≈ 141.4 in²

The area of icing on the cake is about 141.4 square inches.
