Because a negative square root is an impossible number, you use "i". Then you just solve for the square root of 100, which is 10.

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
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.
Please do 24 1/2 - 19 5/8
Answers
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]

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
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.

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
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.

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

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

The number of 3rd-grade students is 9 less than the number of 4th-grade students. The number of 2nd-grade student is 10 less than the number of 5th-grade students. How many students are in each grade.
Answers
There are 0.19(500) or 95 students in grade 4.
The number of students in 3rd grade is 95-9 or 86 students.
So, there are a total of 266 students from grade 1,3 and 4. This leaves 234 students for grade 2 and grade 5.
Let n be the number of students in 5th grade; n-10 is the number of students in 2nd grade.
[tex]n+\left(n-10\right)=234[/tex]
[tex]2n=244[/tex]

There are 122 students in grade 5, and there are 112 students in 2nd grade.

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
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.

for the diagram below which equation is the correct use of the distance formula
the last one D is
D= √(11-6)^2 + (5-y2)^2
Answers
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]
Which is the required equation.
