(I forgot how to do taxes and discounts)
Answers
For taxes do the same thing but instead of subtracting add your product to the amount.
You just have to multiply by the percentage when it's a discount and subtract it from the original amount, 50% becomes .50. 99.50*.5=49.75 99.4-49.75=$47.75
2) D 103.48
You multiply by the percentage (0.04) and then add it to the original price when it's a tax
3) D 4.74
The same process as tax multiply by percentage (.2) and add to the original price
The difference between a markup and tax is the store controls the markups while taxes are usually state-controlled on a certain product (soda 5c or 10c tax is by state)

draw a rectangle that has a perimeter of 12 units and an area of 8 square units
Answers
The dimensions are either 4 units by 2 units or 2 units by 4 units.
To draw a rectangle with a perimeter of 12 units and an area of 8 square units, we need to find the dimensions of the rectangle first.
Let l be the length of the rectangle and w be the width of the rectangle.
We know that the perimeter of a rectangle is given by: P = 2(l + w) =12
12 = 2(l + w) ,6 = l + w
Also, the area of a rectangle is given by: A = l * w = 8
Now, we need to find a pair of numbers l and w that satisfy both equations: 6 = l + w and 8 = l * w
One such pair is l = 4 and w = 2 , because ( 4 + 2 = 6 ) and ( 4 * 2 = 8 ).
This rectangle has a length of 4 units and a width of 2 units, with a perimeter of 12 units and an area of 8 square units.

The athlete’s salary, in thousands, for the first two years is $400 and $400(1.05). Explain how to find her salary for each of the next three years. Do these values form a geometric sequence? Explain.

where
[tex]a_{n}[/tex] is the nth term of the sequence
[tex]a_{1}[/tex] is the first term in the sequence
[tex]r[/tex] is the common ratio
[tex]n[/tex] is the position of the term in the sequence
To check if the values $400 and 400(1.05) for a geometric sequence, we are going to find their common ratio. To find the common ratio, we are going to use the formula [tex]r= \frac{a_{n} }{a_{n-1}} [/tex]
where
[tex]a_{n}[/tex] is the current term in the sequence
[tex]a_{n-1}[/tex] is the previous term in the sequence
We can infer from our values, that the current term of the sequence is 400(1.5), so [tex]a_{n-1}=400(1.5)[/tex]. That leaves 400 as the previous term, so [tex]a_{n-1}=400[/tex]. Lets replace those values in our formula to find [tex]r[/tex]:
[tex]r= \frac{a_{n} }{a_{n-1}} [/tex]
[tex]r= \frac{400(1.05)}{400} [/tex]
[tex]r=1.05[/tex]
Now that we have our common ratio, we can replace it in our formula for the nth term to find the athlete's salary for each of the next three years. Notice that the first term of our sequence is $400, so [tex]a_{1}=400[/tex]
[tex]a_{n}=a_{1}r^{n-1}[/tex]
[tex]a_{n}=400(1.05)^{n-1}[/tex]
[tex]a_{3}=400(1.05)^{3-1}[/tex]
[tex]a_{3}=400(1.05)^{2}[/tex]
[tex]a_{3}=441[/tex]
[tex]a_{4}=400(1.05)^{4-1}[/tex]
[tex]a_{4}=400(1.05)^{3}[/tex]
[tex]a_{4}=463.05[/tex]
[tex]a_{5}=400(1.05)^{5-4}[/tex]
[tex]a_{5}=400(1.05)^4[/tex]
[tex]a_{5}=486.2025[/tex]
We can conclude that the athlete's salary for each of the next three years is: $441,$463.05,486.2025 respectively. Also, those vales for a geometric sequence because they share a common ratio, (1.05).

Brand is combining the leftovers from two batches of chili to serve for dinner tonight. There are 1 1/3 cups of chili left over from the first batch of chili, and there are 3 3/4 total cups of chili left over.
1 1/3 + x = 3 3/4
How many cups of chili were left over from the second batch of chili?
A. 2 5/12
B. 5 1/12
C. 4 1/2
D. 1 5/12
Answers
Brand had 2 5/12 cups of chili left over from the second batch (option A). This was determined by solving the equation 1 1/3 + x = 3 3/4 using improper fractions and subtraction.
To find out how many cups of chili were left over from the second batch, we need to solve for x in the equation 1 1/3 + x = 3 3/4. Firstly, convert the mixed numbers to improper fractions: 1 1/3 becomes 4/3 and 3 3/4 becomes 15/4.
Now the equation looks like this: 4/3 + x = 15/4. To find x, subtract 4/3 from both sides of the equation.
15/4 - 4/3 = (15*3 - 4*4)/(4*3) = 45/12 - 16/12 = 29/12.
Now convert the improper fraction back to a mixed number. 29/12 is 2 and 5/12. So Brand had 2 5/12 cups of chili left over from the second batch (option A).
Lisa is asked to draw a triangle with the following specifications:

the side between the two complementary angles has a length of 12 centimeters
Which of the following statements about this triangle is true?
A.
Exactly one triangle exists with the given conditions, and it must be an isosceles triangle.
B.
More than one triangle exists with the given conditions, and all instances must be right triangles.
C.
More than one triangle exists with the given conditions, and all instances must be isosceles triangles.
D.
Exactly one triangle exists with the given conditions, and it must be a right triangle.
Answers
Since two of the angles are complementary, adding up to 90°, the third angle must be 180-90=90°.
However, this does not mean only one triangle exists. The only information we are given about the two angles is that they are complementary. This could be 30 and 60; 45 and 45; or multiple other combinations. This means there is more than one triangle that fits these criteria.
Final answer:
Triangles with two complementary angles must be right triangles. Since these angles add up to 90 degrees, the side between them is part of a right triangle. There can be many different right triangles that satisfy these conditions, but all must have a 90-degree angle. (Option D)
Explanation:
The question asks about the conditions that define a certain type of triangle. With two angles being complementary, they add up to 90 degrees. In geometry, a complementary pair of angles adds up to 90 degrees, which means that the two angles in question must be acute angles that add up to form a right angle. Therefore, the triangle with two complementary angles must be a right triangle.
Since the triangle can have many different dimensions for the other sides and angles while keeping the side between the complementary angles at 12 centimeters, we can infer that there are infinite variations of this triangle, each with different measures for the remaining side and angle. However, all those triangles must satisfy the condition of being right triangles.
Thus, the correct answer to this question is:
D. Exactly one triangle exists with the given conditions, and it must be a right triangle.
Rajeev has \$175$175dollar sign, 175 that he earned from his summer job. He puts the money in an account that yields 4\%4%4, percent interest compounded annually. Assume that Rajeev does not make any other deposits or withdrawals from his account. After how many years from the time he deposited the money will Rajeev have at least \$200$200dollar sign, 200 in his account?
Answers
It will take 4 yrs for Rajeev to reach 200$
To find out after how many years Rajeev will have at least $200 in his account, we can use the formula for compound interest. P = $175, A = $200, r = 0.04, n = 1, and t = ? Substituting these values into the formula and solving for t, we find that it will take approximately 7.38 years for Rajeev to have at least $200 in his account.
Explanation:To find out after how many years Rajeev will have at least $200 in his account, we can use the formula for compound interest, which is given by:
A = P(1 + r/n)^(nt)
Where:
A is the final amount in the accountP is the initial amount depositedr is the interest rate (expressed as a decimal)n is the number of times interest is compounded per yeart is the number of yearsIn this case, we have:
P = $175A = $200r = 0.04n = 1 (compounded annually)t = ?Substituting these values into the formula, we get:
$200 = $175(1 + 0.04/1)^(1t)
Simplifying the equation, we have:
1.1429 = (1.04)^t
To solve for t, we can take the logarithm of both sides:
log(1.1429) = log((1.04)^t)
Using logarithmic properties, we have:
t log(1.04) = log(1.1429)
Dividing both sides by log(1.04), we get:
t = log(1.1429)/log(1.04)
Using a calculator, we find that t ≈ 7.38
Therefore, it will take approximately 7.38 years for Rajeev to have at least $200 in his account.

divide 660 g in the ratio 4 : 7
Answers
Final answer:
To divide 660 grams in a 4:7 ratio, you first calculate the value of each part by dividing 660 grams by 11 (the sum of the ratio parts), resulting in 60 grams per part. Then multiply 60 grams by 4 to get 240 grams, and by 7 to get 420 grams, giving you two portions that comprise the ratio 4:7.
Explanation:
To divide 660 grams in the ratio 4:7, first add the two parts of the ratio together to find the total number of parts. This is 4 + 7 = 11 parts in total. The ratio indicates that for every 11 parts of the total weight, 4 parts should be in one portion and 7 parts in another. To find the weight of each part, divide the total weight (660 g) by the total number of parts (11).
660 g ÷ 11 = 60 g per part
Now, to get the weights for the two portions:
For the 4 parts: 60 g/part × 4 = 240 grams
For the 7 parts: 60 g/part × 7 = 420 grams
Thus, 660 grams divided in the ratio 4:7 of gives two portions of 240 grams and 420 grams, respectively.

Solve: q to the second power =36
Answers
The equation q^2=36 has two solutions because both a positive and a negative number squared can result in a positive number. The solutions are q=6 and q=-6, illustrating the concept of integer powers and square roots.
Explanation:To solve the equation q squared equals 36 (q2 = 36), we look for the number that, when multiplied by itself, gives the product of 36. In mathematics, finding a value that satisfies this condition involves taking the square root of both sides of the equation. Thus, we have two potential solutions since both positive and negative values can be squared to yield a positive result.
The square root of 36 is 6, so our equation gives us two possible solutions: q = 6 or q = -6. This demonstrates the concept of integer powers, where for instance, raising 4 to the power of 3 (43) means multiplying 4 by itself three times. When dealing with the square root, we are essentially doing the opposite: we are asking what number multiplied by itself gives us the original number under the square power.
