Solution
Here we have to use compound interest formula for half year.
6 months = 1/2 years
Amount = [tex]P(1 + \frac{r/2}{100})^2n[/tex]
R = Rate
P = Principle
n = number of years
Here P = 6000, r/2 = 3.5/2 = 1.75, n = 1/2
Plug in the given values into the formula, we get
A = 6000(1 + 1.75/100)^2(1/2)
A = 6000(1 + 0.0175)^1
A = 6000(1.0175)
A = $6105
Compound interest = A - P
= $6105 - $6000
Interest = $105

Lupe’s chili recipe makes 12 servings and uses 12 green peppers and 4 red peppers. Drag green peppers and red peppers into the box to show how many Lupe needs for 9 servings.
Answer: 9 green peppers and 3 red peppers
Step-by-step explanation:
Lupe makes 12 servings:
She uses 12 green peppers and 4 red peppers.
If you want to know the number of each pepper that she needs for servings, you must divide the number of peppers by the number of servings:
green : 12/12 = 1
She needs one green pepper for serving:
red: 4/12 = 1/3
She needs one third of a red pepper for serving, so for 9 servings she needs:
9*1 = 9 green peppers
9*(1/3) = 9/3 = 3 red peppers
A computer sales associate makes $110 each day that she works and makes approximately $19 in commission for each computer that she sells. If she wants to make at least $338 in one day, at least how many computers does she need to sell?A computer sales associate makes $110 each day that she works and makes approximately $19 in commission for each computer that she sells. If she wants to make at least $338 in one day, at least how many computers does she need to sell?
Find out what number $350 is 8% of, since he makes 8% commission on sales. In the percent formula: a = pb
a is the part, p is the percent (as a decimal), b is the base
350 is 8% of what number? 350 = 0.08b {substituted given values into percent formula and changed 8% to a decimal}
b = $4,375 {divided each side by 0.08}
He needs to make at least $4375 worth of sales.
Jaycie has a VIP membership to a movie theater, so she pays $27 a year and $6.00 for each movie she sees. Claire doesn’t have a membership, so she pays $8.25 each movie she sees. How many movies would they have to see in a year in order to pay the same amount that year?
What you would have to do for this problem is set up an equation for a year and equal them out. The equation would be 27+6x = 8.25x.
X = each visit to the movie.
Now all you have to do is solve the equation. Subtract 6x from 8.25x, and get 27=2.25x. Then, divide 2.25 from 27, and you would get your answer, which is 12. So, they would both have to see 12 movies to pay the same amount that year.
To check your work to see if you were right, you would plug in 12 as x, because that is the variable that represents the amount of visits to the movie. For Jaycie, the equation would be 27+6.00(12), and you would get 99, so she would pay $99 in total. For Claire, you would just do 8.25(12), which is also 99. That is how you know your answer is right.
Hope I helped, it would be greatly appreciated if you gave me brainliest if you understood what I explained :)
They'll need to see 12 movies together before they pay the same amount.
Let the number of movies be x
Based on the question given, the equation for Jaycie will be:
= 27 + (6 × x)
= 27 + 6x
The equation for Clarie will be:
= 8.25 × x
= 8.25x
Then, the equation to solve the question will be:
27 + 6x = 8.25x
Collect like terms
27 = 8.25x - 6x
2.25x = 27
x = 27/2.25
x = 12
They will see 12 movies together.

Imani spent half of her weekly allowance playing mini-golf. To earn more money her parents let her wash the car for $4. What is her weekly allowance if she ended with $12?
16 is her weekly allowence
Imani's weekly allowance is $16. This is determined by setting up and solving an algebraic equation based on the information provided in the problem.
Explanation:Let's use the information given in the problem. The student, Imani, had an initial allowance. She spent half of it on mini-golf and then earned an extra $4 by washing a car. After these transactions, she has $12 remaining. We can use this to set up a simple algebraic equation.
Let x be the initial allowance. We know from the problem that Imani spent half of it, which is 0.5x, on mini-golf and earned an extra $4. So, the equation can be written as:
0.5x + $4 = $12
Solving this equation gives the weekly allowance. If we subtract $4 from both sides of the equation, we get 0.5x = $8. If we then divide each side by 0.5, we find that x = $16.
So, Imani's weekly allowance is $16.

Problem: A karate team had 6 girls and 9 boys. Then 2 more girls and 3 more boys joined the team. Did the ratio of girls to boys stay the same?Explain.
The ratio of girls to boys in the karate team remained the same at 2:3, both before and after the new members joined.
Initially, there were 6 girls and 9 boys, creating a ratio of 6 girls to 9 boys, which simplifies to 2:3 when divided by the greatest common divisor, 3. After 2 more girls and 3 more boys joined, the team had 8 girls and 12 boys.
This new ratio also simplifies to 2:3, since both the numerator and denominator can be divided by 4. Therefore, the ratio of girls to boys did not change after the new members joined the team; it remained the same at 2 girls for every 3 boys.

How can you tell from the graph of Molly's garden on the previous slide that it represents a proportional relationship?
Answer:
A proportional relationship is a relation of the form:
Y = A*X
This means that if we have two variables, X and Y, for each unit that X grows, Y grows A times that.
And notice that the relation:
Y/A = X
is also a porportional relationship
This relationship can be expresed in a graph as a straight line that pases through the origin and has a constant unit of growht (in this case A) that is also called the "slope" of the line.
The graph of a proportional relationship has the same unit rate, is a straight line, and starts at the origin.
If the denominators of two fractions are the same, how do you add the fractions?
Step-by-step explanation: To add like fractions or fractions or fractions that have the same denominator, simply add the numerators and keep the original denominator.
Let's try an example.
[tex]\frac{1}{13}[/tex] + [tex]\frac{5}{13}[/tex] = ?
In this example, if we add the numerators we have 1 + 5 which gives us 6 and we put this over our original denominator which is 13. Therefore, 1/13 + 5/13 . gives us 6/13 which is in lowest terms.
write an equation for the line that passes through (5,-4) and is perpendicular to the graph of 5x -2y=-6
Answer:
y = (-2/5)x - 2
Step-by-step explanation:
One way to attack this problem is to interchange the coefficients of x and y and change the sign of one to +: 5x - 2y = -6 becomes 2x + 5y = c. Solving for the slope, m, we get 5y = -2x + c first, and then y = (-2/5)x + D.
Subbing 5 for x and -4 for y, we now have -4 = (-2/5)(5) + D.
Then -4 = -2 + D, so that D = -2.
The desired equation is thus y = (-2/5)x - 2.
Check: Does this pass through (5, -4)? Is -4 = (-2/5)(5) - 2 true? Yes.
Is the slope -2/5 the negative reciprocal of 5/2? Yes, it is.

Select all the equations where m= 4 is a solution
Choose 3 answers:
A) 13 = 9 + m
B)7- m = 3
C) 15 = 11m
D) 5 = m + 2
E) 20 divide m =5
Answer:
A, B, E
Step-by-step explanation:
A) 13=9+m
m= 13-9
m=4 ✔️
B) 7-m =3
m= 7-3
m=4 ✔️
C) 15= 11m
15=11*4
15≠44
D) 5= m+2
If m=4 therefore
5≠4+2
5≠6
E) 20 divide m = 5
20/4 = 5
therefore, m=4 ✔️
By substituting m=4 into each equation, we find that options A) 13 = 9 + m and E) 20 divided by m = 5 are the correct equations where m=4 is a solution.
Explanation:In mathematics, specifically algebra, we can solve and check equations by plugging in values. You are asked to find the equations where m = 4 is a solution.
Let's substitute m with 4 in each equation:
A) 13 = 9 + m becomes 13 = 9 + 4. Hence, 13 = 13 which is true. B) 7- m = 3 becomes 7 - 4 = 3 so it is incorrect because 3 is not equal to 7 - 4. C) 15 = 11m becomes 15 = 44 which is incorrect. D) 5 = m + 2 becomes 5 = 4 + 2 which is incorrect because 5 is not equal to 6. E) 20 divided by m = 5 becomes 20 divided by 4 equal to 5. So, 5 = 5 is correct.Therefore, the equations where m=4 is a solution are A) 13 = 9 + m and E) 20 divided by m = 5.

In a triangle the length of two sides are 1.9m and 0.7m. What is the length of the third side, if you know that it should be a whole number?
Answer:
2
Step-by-step explanation:
A side of a triangle is less than the sum of the lengths of the other two sides and is greater than the positive difference of them.
third side is in between 1.2 and 2.6 but it has to be a whole number so its 2
A possible measure of the third side is 2m (to the nearest whole number)
Using the triangular theorem which states that the measure of the third side of the triangle is less than the sum of the other two sides.
Given the length of the other two sides as 1.9m and 0.7m
Taking the sum
Sum of other two sides = 1.9m + 0.7mSum of other two sides = 2.6mSince the length of the third side must e less than the sum, hence the required answer must be less than 2.6m.
A possible measure of the third side is 2m (to the nearest whole number)

If kara lines up all 3/4 inch button what would be the total if the length?
To find out the total length of the buttons when lined up, multiply the number of buttons by the length of one button (3/4 inch). An expression for this would be L = n imes (3/4). A button is considered pressed if the extended key length K* is greater than or equal to LO, the rest length of the lock.
Explanation:If Kara lines up all her 3/4 inch buttons, the total length of the buttons aligned in a row can be found by multiplying the number of buttons by the length of one button. Let's denote the number of buttons as n, and the length of one button as 3/4 inches. Hence, the expression for the total length L would be L = n imes (3/4) inches. If the key K* finally stops at a position that is greater than or equal to the rest length of the lock LO, then the button will be pressed.
To determine whether the button will be pressed, we could set up an inequality: K* \\geq LO. If this condition holds true, Kara knows that the button is pressed.
