Answer 1

5. 120% is the same as 1.2 (from the percentage symbol go to places to the left and place a decimal). So we do:

5x + 5x(1.2)

Simplify to get:

5x + 6x = 11x

6. 7z - 1/3(7z)

Simplify the equation to get:

[tex]7z - \frac{7}{3} z[/tex]

Rewrite as:

[tex] \frac{21}{3}z - \frac{7}{3} z[/tex] and combine like terms to get [tex] \frac{14}{3} z[/tex]

8. [tex] \frac{3}{4}v - 6( \frac{2}{9}y) [/tex]

Rewrite as:

[tex] \frac{3}{4} v - \frac{12}{9}y [/tex]

And simplify to get:

[tex] \frac{3}{4}v - \frac{4}{3}y [/tex]

10. [tex]2x + \frac{2}{3}x + 5 + 11 - x [/tex]

Combine like terms:

[tex]x + \frac{2}{3}x + 16 [/tex] which becomes [tex] \frac{3}{3}x + \frac{2}{3} x + 16 [/tex]

Do it again and get your answer:

a basketball court is a rectangle with a perimeter of 1040 feet. The length is 200 feet more than the width. What is the width and length of the basketball court?

Answers

if you do 1040-400 you get 640
then you need to divide that by 4 to get 160 leaving you with the width, to get the length you have to add 200 to the width meaning the length is 360

length = 360
width = 160

Length = width + 200

[tex]x + x + x + 200 + x + 200 = 1040 \\ 4x + 400 = 1040 \\ 4x = 640 \\ x = 160[/tex]
Length = 160 + 200 = 360 feet

Answer :
Width = 160 feet,
Length = 360 feet

two more than the product of a number and 8 is 5

Answers

When ever the problem says is, the next number after that is going to be the answer to the equation. So now you have =5.

Next it say two more which means adding so now we have, +2=5

Now we have the product of a number and 8. This means that the number and 8 equal the product. Now we know that an answer that is a product is a multiplication problem. That means that you have to multiply 8 and the number.

That leaves us with the answer, n•8+2=5

The unknown number is [tex]$ \frac{3}{8} $.[/tex]

Let's solve the problem step by step.

Given: Two more than the product of a number and 8 is 5.

Let's denote the unknown number as [tex]$ x $[/tex].

According to the problem, we can express the given condition in an equation:

[tex]\[8x + 2 = 5\][/tex]

To find the value of [tex]$ x $[/tex], we need to isolate it on one side of the equation. We'll begin by subtracting 2 from both sides to get rid of the constant term on the left side:

[tex]\[8x = 5 - 2\][/tex]

[tex]\[8x = 3\][/tex]

Now, to solve for [tex]$ x $[/tex], we'll divide both sides of the equation by 8:

[tex]\[x = \frac{3}{8}\][/tex]

So, the solution to the equation is [tex]$ x = \frac{3}{8} $.[/tex]

Now, let's provide a brief explanation:

The equation [tex]$8x + 2 = 5$[/tex] is formed based on the given problem statement. By subtracting 2 from both sides and then dividing by 8, we isolate the variable [tex]$ x $[/tex] to find its value, which is [tex]$ \frac{3}{8} $.[/tex]

Thus, the correct answer is:

[tex]\[ x = \frac{3}{8} \][/tex]

Jennie says the experimental probability that a 7th grade student reads at least 100 pages per week is 16/125. What is her error and the correct experimental probability?

HERE IS THE CHART

| pages | 6th | 7th | 8th| {Grades}

| 75 pages | 24 | 18 | 22 |

| 100 pages | 22 | 32 | 24 |

| 150 pages | 30 | 53 | 25 |

Answers

The correct probability is 85/103. Her errors were that she only took the number of 7th grade students that read 100 pages per week; she did not include the number of students that read more than that, and she wrote the denominator of the probability as the number of pages read instead of the total number of seventh grade students.

32 seventh grade students read 100 pages per week. 53 students read 150 pages per week. This is out of 18+32+53=103 seventh grade students. This gives us 32+53=85/103.

Jennie incorrectly calculated the experimental probability of a 7th grader reading at least 100 pages per week. The correct calculation is the sum of 7th graders who read 100 and 150 pages, divided by the total number of 7th graders, resulting in an experimental probability of 85/103.

Jennie's error lies in calculating the experimental probability that a 7th grade student reads at least 100 pages per week incorrectly. To find the correct experimental probability, we need to add the number of 7th graders reading 100 pages and those reading 150 pages, then divide by the total number of 7th graders. According to the chart, 32 read 100 pages and 53 read 150 pages. The total number of 7th graders is the sum of students reading 75, 100, and 150 pages, which is 18 + 32 + 53 = 103. So, the correct experimental probability is (32 + 53) / 103 = 85 / 103.

Answers

the Answer is A, verified apex

Answer: The correct equation is,

[tex]6.71=\sqrt{ (11-5)^2+(y_2-6)^2}[/tex]

Step-by-step explanation:

If [tex](x_1,y_1)[/tex] and [tex](x_2,y_2)[/tex] are the endpoints of a line segment,

Then by the distance formula,

The length of the line segment is,

[tex]d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}[/tex]

Here, (5,6) and (11, [tex]y_2[/tex] ) are the endpoint of the line segment which has the length 6.71,

Thus, d = 6.71, [tex]x_1=5[/tex] [tex]y_1=6[/tex], [tex]x_2=11[/tex]

[tex]\implies 6.71 = \sqrt{ (11-5)^2+(y_2-6)^2[/tex]

A quadrilaterals angles = 360°

three angles are given, with the fourth as x: 90, 80, 74, x

Add all the angles together and set it equal to 360

90 + 80 + 74 + x = 360

Simplify. Combine like terms

x + 244 = 360

Isolate the x, subtract 244 from both sides

x + 244 (-244) = 360 (-244)

x = 360 - 244

x = 116

116° is your answer

Kelly has 236 feet of fence to use to enclose a rectangular space for her dog. She wants the width to be 23 feet. Draw a rectangle that could be the space for Kelly's dog. Label the length and the width.

Answers

perimeter = 236 ft

length=?

p= 2l+2w

236=2l+2(23)

236=2l+46

190=2l

l= 95ft

Final answer:

To create the space for Kelly's dog, a rectangle with a length of 118 feet and a width of 23 feet should be drawn.

Explanation:

To draw a rectangle that could be the space for Kelly's dog, we need to consider the given information. Kelly has 236 feet of fence to use, and she wants the width to be 23 feet.

Since the opposite sides of a rectangle are equal in length, we can divide the total amount of fence by 2 to determine the length of each side. 236 feet / 2 = 118 feet.

So, the rectangle that could be the space for Kelly's dog would have a length of 118 feet and a width of 23 feet.

Brianna took out a car loan for $12,250 that has a 0% APR for the first 20 months and will be paid off with monthly payments over a 4 years. For how many months will Brianna be charged interest.

Answers

Brianna doesn’t have any interest, determined by the 0% APR for 20 months. This is 1 year and 8 months. If she plans on making the payments for 4 years then her interest months is 4 years (48 months) minus 20 months, leaving her with 28 months of being charged interest. 28 months is 2 years and 4 months.

Final answer:

Brianna will be charged interest for 28 months.

Explanation:

To determine how many months Brianna will be charged interest, we need to first calculate the total number of months she will be making payments. Since there are 4 years in total, and each year has 12 months, the total number of months is 4 years * 12 months/year = 48 months.

For the first 20 months, Brianna has a 0% APR and will not be charged interest. So we subtract these 20 months from the total number of months to find out how many months she will be charged interest: 48 months - 20 months = 28 months.

Therefore, Brianna will be charged interest for 28 months.

Brian wants to buy a motorcycle and is planning to get motorcycle insurance. Suppose the average accident rate is 0.1, and the average expenses incurred on accidents is $38,000. The insurance plan has a yearly premium of $1,000 and a deductible of $4,000.
If after 4 years of insuring 100 people, 9 motorcycle drivers had an accident, where does the company stand after money has been taken in and paid out for this group of 100 insured people?

$85,500
-$36,000
$94,000
$58,000

Answers

It's $94,000

1,000 X 100 X 4 = 400,000

Answer:

The correct option is $94,000

Step-by-step explanation:

Yearly premium under the insurance plan = $1,000

Total premium from single motorcycle driver in 4 years = $1,000 * 4 = $4,000

Number of people insured = 100

Total premium collected from 100 motorcycle drivers = $4,000 * 100 = $400,000

Average expenses incurred on accident = $38,000

Deductible = $4,000

Net expenses incurred per accident = $38,000 - $4,000 = $34,000

In 4 years , 9 motorcycle drivers had an accident

Total expenses incurred for accident = $34,000 * 9 = $306,000

Net savings of Insurance Company = total premium - total expenses = $400,000 - $306,000 = $94,000

Hope it helps.

Ms. Ito's art class used 2/3 of bottle of blue paint. If they used 1/4 as much red paint as blue paint. How many bottles of red paint did they use?

Answers

The answer is 1/6 bottles of red paint. For how I got it was I multiplied 2/3*1/4 which was 2/12 and when u simplify it, your answer is 1/6. Hope this helped!!!

Final answer:

The class used 2/3 of a bottle of blue paint and 1/4 as much red paint, which means they used 1/6 of a bottle of red paint.

Explanation:

To solve the problem presented by Ms. Ito's art class, we first need to determine the amount of blue paint used and then calculate the red paint used based on that amount. The class used 2/3 of a bottle of blue paint. Since they used 1/4 as much red paint as blue paint, we need to divide the amount of blue paint by 4 to find the amount of red paint used.

Calculation: (2/3) ÷ 4 = 2/3 ÷ 1/4 = (2×1)/(3×4) = 2/12 = 1/6

Therefore, the class used 1/6 of a bottle of red paint.

Answers

The first step for solving this expression is to know that since both of the expression are equal to y,, we must set them each to each other to form an equation in x. This will look like the following:
-3x + 7 = -3x - 6
Now cancel equal terms on both sides of the equation.
7 = -6
This tells us that the statement is false for any value of x and y,, so our answer is (x,y) ∈ ∅,, or no solution (option D).

Please do 24 1/2 - 19 5/8

Answers

In order to subtract mixed numbers, the easiest way to do it is to make them into improper fractions.

In order to do that, multiply the whole number by the denominator and add it to the numerator.

That would make 24 [tex] \frac{1}{2}[/tex] into [tex] \frac{49}{2} [/tex].

Also, it'd make 19 [tex] \frac{5}{8}[/tex] into [tex] \frac{157}{8} [/tex].

Now that they're both improper fractions, you need to make them have a common denominator in order to actually subtract them. You can do that by multiplying the numerator and denominator of [tex] \frac{49}{2} [/tex] by 4, to make it stay the same fraction, but have the same denominator as [tex] \frac{157}{8} [/tex].

[tex] \frac{49}{2} = \frac{196}{8} [/tex]

Now we can subtract them!

[tex] \frac{196}{8} - \frac{157}{8} = \frac{39}{8} [/tex]
When subtracting fractions, only subtract the numerators. You don't subtract the denominators.

The final answer is [tex] \frac{39}{8} [/tex]
