Choose the answer that BEST describes the situation. * 1 point A. The shirt will have the lowest price with the $20 off coupon. B. The shirt will have the lowest price with the 20% off coupon. C. The shirt will cost the same with either coupon. D. It depends on the cost of the shirt as to which coupon will help John pay the lowest price.
Answer: D. It depends on the cost of the shirt as to which coupon will help John pay the lowest price.
Step-by-step explanation:
Given two different coupon options :
First: 20% off
Second = $20 off
To our hase with one which enables one to pay the amount of money :
The price of the shirt will determine which of the coupons will give the least amount. For instance, a shirts which which cost below $100 will require the $20 off coupon in other to attain the least payment amount. However for shirts which cost above $100, the 20% coupon yield the least amount. Shirts which cost $100. Both coupons yields the same discount amount.

Action movies make up 25% of Sara’s DVD collection. If she has 16 action DVDs, how many DVDs does Sara have in her collection?
Answer:
64 DVDs
Step-by-step explanation:
25% = 16 DVDs
25%x 4 = 16x 4
100% = 64 DVDs
If action movies make up 25% of Sara’s DVD collection. If she has 16 action DVDs, how many DVDs does Sara have in her collection will be 64
First step is to convert the decimal to fraction
16÷24÷100
Second step is to reduce the fraction
16÷1÷4
Third step is to divide the fraction by multiplying its reciprocal in order to determine how many DVDs does Sara have in her collection
16×4
=64
Inconclusion if action movies make up 25% of Sara’s DVD collection. If she has 16 action DVDs, how many DVDs does Sara have in her collection will be 64

Classify a triangle with side lengths of 9, 12, 17
A. Right
B. Acute
D. obtuse
Answer:
B.
Step-by-step explanation
give me brainliest
Side length 9, 12, 17 forms a obtuse angled triangle.
What is Pythagorean triplets?"Pythagorean triplets are combination of such three numbers which satisfy the Pythagoras theorem a² + b² = c²."
Formula used
Pythagoras triplet
c = hypotenuse
'a' and 'b' other two sides of a triangle
a² + b² = c² (Right angled triangle)
a² + b² ≤ c² (Obtuse angled triangle)
a² + b² ≥ c² (Acute angled triangle)
According to the question,
Given
Side length of a triangle = 9, 12, 17
Substitute the value in the formula of Pythagoras triplet we have,
a² = 81
b² =144
c² =289
c² > a² +b²
Therefore, triangle with side length 9, 12, 17 forms a obtuse angled triangle
Hence, Option(D) is the correct answer.

The formula for the perimeter of a rectangle is P=2(l+w). Solve for l.
Answer:
l = [tex]\frac{P-2w}{2}[/tex]
Step-by-step explanation:
Given
P = 2(l + w) ← distribute right side
P = 2l + 2w ( subtract 2w from both sides )
P - 2w = 2l ( isolate l by dividing both sides by 2 )
[tex]\frac{P-2w}{2}[/tex] = l
Answer:
l=‒2w+p/2
Step-by-step explanation:
p=2(L+w)
p=2L+2w(add ‒2w on both sides)
‒2w+p=2L+2w-2w
‒2w+p=2L
‒2w+p/2=2L/2
L=‒2w+p/2

Which card is incorrect and why?

C.3
Answer:

Step-by-step explanation:
You must divide the 7 from all parts of the equation, not only from the y.
Answer:
A because that is the way you have to write it
calculate without using tables the values of
(1+√2)⁴ - (1-√2)⁴
=========================================================
Work Shown:
A = 1+sqrt(2)
B = 1-sqrt(2)
-------------------
Using A and B, let's add and subtract those values
A+B = (1+sqrt(2))+(1-sqrt(2))
A+B = 1+sqrt(2)+1-sqrt(2)
A+B = 1+1+sqrt(2)-sqrt(2)
A+B = 2
and
A-B = (1+sqrt(2))-(1-sqrt(2))
A-B = 1+sqrt(2)-1+sqrt(2)
A-B = 1-1+sqrt(2)+sqrt(2)
A-B = 2sqrt(2)
-------------------
Next, square both sides of the A equation
A^2 = (1+sqrt(2))^2
A^2 = (1+sqrt(2))(1+sqrt(2))
A^2 = 1(1+sqrt(2))+sqrt(2)(1+sqrt(2))
A^2 = 1+sqrt(2)+sqrt(2)+sqrt(2)*sqrt(2)
A^2 = 1+2sqrt(2)+2
A^2 = 3+2sqrt(2)
-------------------
Do the same for B
B^2 = (1-sqrt(2))^2
B^2 = (1-sqrt(2))(1-sqrt(2))
B^2 = 1(1-sqrt(2))-sqrt(2)(1-sqrt(2))
B^2 = 1-sqrt(2)-sqrt(2)-sqrt(2)*(-sqrt(2))
B^2 = 1-2sqrt(2)+2
B^2 = 3-2sqrt(2)
There's a bit of nice symmetry going on with A^2 and B^2, due to A and B having similar symmetric structures themselves.
-------------------
Lets add A^2 to B^2
A^2+B^2 = (3+2sqrt(2)) + (3-2sqrt(2))
A^2+B^2 = 3+2sqrt(2) + 3-2sqrt(2)
A^2+B^2 = 3+3+2sqrt(2)-2sqrt(2)
A^2+B^2 = 6
-------------------
Now onto the final event
We'll use the difference of squares rule twice
Afterward, apply substitution using the previous sections above.
A^4 - B^4 = (A^2)^2 - (B^2)^2
A^4 - B^4 = (A^2-B^2)(A^2+B^2)
A^4 - B^4 = (A-B)(A+B)(A^2+B^2)
A^4 - B^4 = (2sqrt(2))(2)(6)
A^4 - B^4 = 2*6*2*sqrt(2)
A^4 - B^4 = 24*sqrt(2)
(1+sqrt(2))^4 - (1-sqrt(2))^4 = 24*sqrt(2)
-------------------
To check this with your calculator, you can type in the following
(1+sqrt(2))^4 - (1-sqrt(2))^4 - 24*sqrt(2)
The result you should get should be 0, or very close to it

Which problem solving strategy would be best to solve this problem? Four people are in line at the movie theater. Jennifer is ahead of Jeanie. John is not first or last in line. Jarett is directly in front of Jennifer. Name the order in which the people are standing in line. A. guess, check and revise B. compute or simplify C. work backwards D. write an equation
Answer:
C. work backwards
Step-by-step explanation:
Given from the first statement of the question that that four people are in line. This is the result of the question, so the strategy required would be the work backwards.
Jennifer is ahead of Jeanie implies that Jeanie is somewhere behind Jennifer. Since John is neither the first or the last in the line, then he must be between Jeanie and Jennifer. And Jarett is directly in front of Jennifer, so that Jarett is the first in line. The arrangement goes thus:
Jeanie ⇒ John ⇒ Jennifer ⇒ Jarett
Answer:
The answer is C, work backwards.

i need to find the domain and range
The required domain is {-5, -4, -2, 0, 1} and range is {4, -4, 1, 4, 3}.
As given in the question, for the ordered pairs given {(-5, 4), (-4,-1), (-2, 1), (0, 4), (1,3)} domain and range of the system is to be determined.
Range, it is the set of the values that come out to an outcome for a certain mathematical operation.
What is simplification?The process in mathematics to operate and interpret the function to make the function or expression simple or more understandable is called simplifying and the process is called simplification.
Here,
Given the ordered pair are,
{(-5, 4), (-4,-1), (-2, 1), (0, 4), (1,3)}
Values in the place of abscissa x and ordinate y are the value of a set of domains and ranges respectively.
So domin = {-5, -4, -2, 0, 1}
and range = {4, -4, 1, 4, 3}
Thus, the required domain is {-5, -4, -2, 0, 1} and range is {4, -4, 1, 4, 3}.

Write a sentence as an equation using the given information in each problem.
1. Write the sentence as an equation.
the product of 371 and d is the same as 52
2. Write the sentence as an equation. n decreased by 320 is equal to 139
3. Write the sentence as an equation. 317 is equal to k plus 110
4. Write the sentence as an equation.
the total of 374 and k is the same as 305
5. Write the sentence as an equation. 398 is the same as d plus 6
Answer:
1. 371 × d = 52
2. n - 320 = 139
3. 317 = k + 110
4. 374 + k = 305
5. 398 = d + 6
Step-by-step explanation:
1. 371 × d = 52
d = 52/371
d = 0.14016172506
2. n - 320 = 139
n = 139 + 320
n= 459
3. 317 = k + 110
k = 317 - 110
k = 207
4. 374 + k = 305
k = 305 - 374
k = -69
5. 398 = d + 6
d = 398 - 6
d = 392
