Answer:
D
Step-by-step explanation:
8 hours and 35 minutes can be rewritten as the mixed fraction 8 35/60.
You can reduce this fraction by dividing the numerator and denominator by 5.
35/5 = 7
60/5 = 12
So, 35/60 = 7/12
Now add 8 to your reduced fraction.
8 + 7/12 = 8 7/12

Rental of space = $68 per guest; Downpayment = 25% of total cost; Payment due one month before the reception includes a 7.4% interest payment on the balance.
This question is incomplete, the complete question is;
PROBLEM SOLVING WITH PERCENTS: You are planning a wedding reception for 75 guests that will take place in exactly 10 months. There are two different sites that you are contemplating using, with the stipulations on payments as described below. Determine the TOTAL cost of renting each location.
Rental of space = $68 per guest; Down payment = 25% of total cost; Payment due one month before the reception includes a 7.4% interest payment on the balance.
Answer: Total Cost of Renting = $5312.29
Step-by-step explanation:
Given that;
Rental space = $68 per guest, down payment = 25%, 7.4% interest payment on the balance.
Total Cost of Renting = Down Payment + Remaining payment
Total Cost of Renting = $68 × Guests × 25% + ($68 × Guest - Down payment) × (1 + Interest *9/12)
Total Cost of Renting = $68 × 75 × 25% + ($68 × 75 - Down payment) × (1 + 7.40% × 9/12)
Total Cost of Renting = $1275 + ($5100 - 1273) × (1.0555)
Total Cost of Renting = $1275 + 4037.29
Total Cost of Renting = $5312.29
Solve 2(x + 1) = 2x + 5
Answer:
no solution
Step-by-step explanation:
Given
2(x + 1) = 2x + 5 ← distribute parenthesis on left side
2x + 1 = 2x + 5 ( subtract 1 from both sides )
2x = 2x + 4 ( subtract 2x from both sides )
0 = 4 ← not possible
This indicates the equation has no solution
Answer:
See below
Step-by-step explanation:
● 2(x+1) = 2x +5
Multiply 2 by (x+1)
● 2x + 1×2 = 2x+5
● 2x + 2 = 2x+5
Substract 2x from both sides
● 2x+2-2x = 2x+5-2x
● 2 = 5
This is impossible, so this equation has no solution.
The area of the top face of a cube is 9 square centimerers. Use 9 of these cubes to make a rectangular prism. What is the volome of the rectangular prism?
Answer:
243 cm³
Step-by-step explanation:
A cube has the same measure in length, width and height. So, we know that the area of the top face of a cube is 9 square centimeters, this means that
Length x width = 9 square centimeters
But, since length and width are the same, we have that they are equal to [tex]\sqrt{9} =3[/tex] cms (since 3² = 9).
Thus, the volume of each cube is 3³ = 27 cm³
We are going to use 9 of these cubes to make a rectangular prism, therefore, the volume of this prism is going to be 9 times the volume of each cube.
Volume of prism = 9 (27) = 243 cm³
Answer:
243 cm³

Define a variable, write an equation, and solve the problem. Adults' tickets to a play cost $5 and students' tickets
cost $2. If 295 tickets were sold and a total of $950 was collected, how many students' tickets were sold?
Answer:
175
Step-by-step explanation:
Let A be the number of adult tickets and S be the student's tickets
{A + S = 295 or S = 295 - A
{5A + 2S = 950
5A + 2(295 - A) = 950
5A + 590 - 2A = 950
3A = 360
A = 120
S = 295 - 120 = 175

Ok, this is just simple math problems think of it like this....
3+p=8 ➡ rearrange the equation
p= 8 - 3 ➡ this is because p has to be added to 3 to make 8
p= 5
Four mathematicians have the following conversation:
Alice: I am insane.
Bob: I am pure.
Charlie: I am applied.
Dorothy: I am sane.
Alice: Charlie is pure.
Bob: Dorothy is insane.
Charlie: Bob is applied.
Dorothy: Charlie is sane.
You are also given that:
● Pure mathematicians tell the truth about their beliefs.
● Applied mathematicians lie about their beliefs.
● Sane mathematicians beliefs are correct.
● Insane mathematicians beliefs are incorrect.
Describe the four mathematicians.
Answer: plz mark as brainliest
Step-by-step explanation:The table below shows the net effect of a person’s mental state and occupation on his or her truth telling.
Suppose that Dorothy is telling the truth. Then she is sane (and hence a pure mathematician) and Charlie is sane. Bob says that Charlie is insane, so Bob is not telling the truth. Since he says he’s pure, he’s actually applied and hence Charlie is telling the truth. But then he’s applied and sane applied mathematicians do not tell the truth. This is a contradiction.
Therefore, Dorothy is not telling the truth. Thus, both Charlie and Dorothy are insane (hence Dorothy is pure). Consequently, Bob is telling the truth. Therefore Bob is pure (and sane, since he is a truth teller). Since Charlie says that Bob is applied, he is not telling the truth. Since we know that he is insane, he must be pure.
Since Alice says that Charlie is pure, she is telling the truth. Therefore she is insane and consequently applied.
In summary:
Alice is an insane applied mathematician.
Bob is a sane pure mathematician.
Charlie is an insane pure mathematician.
Dorothy is an insane pure mathematician.
Alice: Alice claims to be insane. If she is telling the truth, then her belief is incorrect, and she is, in fact, sane.
What is a mathematician?Mathematicians and statisticians solve problems in industry, academia, and government by using formulas and data.
Alice: Alice claims that she is insane. If she's telling the truth, her belief is incorrect, and she's perfectly normal. Alice is thus either pure or applied.
Bob: Bob declares himself to be pure. Bob's belief is correct, and he is indeed pure, because pure mathematicians tell the truth.
Charlie claims to be applied, but Alice claims Charlie is pure. Alice's claim about Charlie is true because applied mathematicians lie, and Charlie is actually pure.
Dorothy: Dorothy asserts that she is sane. Dorothy's belief is correct, and she is indeed sane, because the beliefs of sane mathematicians are correct.
Therefore, the four mathematicians are Alice (either pure or applied), Bob (pure), Charlie (pure), and Dorothy (sane).

Which of the following is most likely the next step in the series?
Answer:
Option (c)
Step-by-step explanation:
From the diagram attached,
First circle has 4 points on its circumference. By joining these points we get a quadrilateral inside the circle.
Second circle has 3 on its circumference. By joining these points we get a triangle inscribed in the circle.
In 3rd circle points on the circumference have been reduced again to 2. By joining these points we get a straight line.
Following the same pattern in the 4th circle we will get a single point on the circumference of the circle.
Therefore, Option (c) will be the answer.

Please help me answer this question! It’s in the picture!
Step-by-step explanation:
We can prove this by using similar triangles. We know that angle ABE and ACD are SIMILAR(we know that by the sign in between them).Therefore, we also know that CDA and BEA are similar, and EAB and DAC are similar. Since all the angles are similar, we also know that the side lengths are equal in proportion. AB/AE is equal to AC/AD. When assigned values, that would create a proportion that is equal since the smaller triangle is similar to the bigger one. If you want to create a proof, break each statement into its own section.
A parallelogram has sides lengths of 7 inches and 11 inches. Find the prerimeter
Answer: 36 in
Step-by-step explanation:
the formula for perimeter: 2(l+w)
length: 7
width/length: 11
2(l+w)

=2(18)
=36 in
Hope this helps!! :)
Please let me know if you have any question
Answer:
The perimeter of the parallelogram is 36 inches.
Step-by-step explanation:
The perimeter of a parallelogram is the addition of all of its side lengths. In a parallelogram, each side length is repeated twice. The perimeter can thus be represented by the following formula:
P = length + length + width + width
Now, we can substitute in the values that we are given in the problem.
P = 11 + 11 + 7 +7
Next, we simply have to add together the remaining values to simplify.
P = 36 inches
Therefore, the perimeter is 36 inches.

Audrey sells closet organization systems. She is paid a commission of 5.14% of her first $1500.00 in sales during the week and 10% on all sales over $1500.00. What is her commission in a week during which she sells $7500.00 worth of closet organization systems?
Answer:
$827.1Step-by-step explanation:
We proceed to calculate the 5.14% of the $1500 in sales during the week
Hence she is paid 1500*(5.14/100)
= 1500*0.0514
= $77.1
And also she is paid 10% of sales over $1500 and she made sales of $7500
her commission is
= (10/100)*7500
=0.1*7500
= $750
Hence in all for the week her commission will be (if she sells $7500)
= 77.1+750
= $827.1

The following are the means and standard deviations of some well-known standardized tests, referred to as Test A, Test B, and Test C. All three yield normal distributions.
Test Mean Standard deviation
Test A 500 100
Test B 150 8
Test C 70 15
Required:
a. A score of 450 on Test A corresponds to what score on Test B?
b. A score of 625 on Test A corresponds to what score on Test C?
Answer:
(a) A score of 450 on Test A corresponds to a score of 146 on Test B.
(b) A score of 625 on Test A corresponds to a score of 88.75 on Test C.
Step-by-step explanation:
We are given the means and standard deviations of some well-known standardized tests referred to as Test A, Test B, and Test C. All three yield normal distributions.
Test Mean Standard deviation
Test A 500 100
Test B 150 8
Test C 70 15
So, [tex]\mu_A[/tex] = 500 and [tex]\sigma_A[/tex] = 100
[tex]\mu_B[/tex] = 150 and [tex]\sigma_B[/tex] = 8
[tex]\mu_C[/tex] = 70 and [tex]\sigma_C[/tex] = 15
(a) We have to find a score of 450 on Test A corresponds to what score on Test B.
For this, firstly we will find the z-score for a score on Test A and then equate with that of Test B.
z-score of 450 on test A = [tex]\frac{X_A-\mu_A}{\sigma_A}[/tex]
= [tex]\frac{450-500}{100}[/tex] = -0.5
So, this z-score corresponds to the score on test B, i.e;
z-score on test B = [tex]\frac{X_B-\mu_B}{\sigma_B}[/tex]
-0.5 = [tex]\frac{X_B-150}{8}[/tex]
[tex]X_B= 150-(0.5 \times 8)[/tex]
= 150 - 4 = 146
Hence, a score of 450 on Test A corresponds to a score of 146 on Test B.
(b) We have to find a score of 625 on Test A corresponds to what score on Test C.
For this, firstly we will find the z-score for a score on Test A and then equate with that of Test C.
z-score of 625 on test A = [tex]\frac{X_A-\mu_A}{\sigma_A}[/tex]
= [tex]\frac{625-500}{100}[/tex] = 1.25
So, this z-score corresponds to the score on test C, i.e;
z-score on test C = [tex]\frac{X_C-\mu_C}{\sigma_C}[/tex]
1.25 = [tex]\frac{X_C-70}{15}[/tex]
[tex]X_C= 70+(1.25 \times 15)[/tex]
= 70 + 18.75 = 88.75
Hence, a score of 625 on Test A corresponds to a score of 88.75 on Test C.

Breanna has $150 and she needs to save at least $560 for spring break trip if she can save $45 per week how long will it take her to save enough money let W equals weeks saving money right and in quality to
Answer: It will take her more than 9 weeks.
Step-by-step explanation:
If she already has $150 that will be constant and if she can save $45 per week the we will have the expression 45w where w is the number of weeks.
Together it will be 150 + 45w
Now the money has to be at least $560 so it will be
150 + 45w ≥ 560 Now solve for w
-150 -150
45w ≥ 410
w ≥ 9.1
Which means it will take 10 or more weeks t

a-b=4
Answer:
a = 12 b = -4
Step-by-step explanation:
To solve this equation it would be easiest to use the elimination method
a + b = 8
a - b = 4
a = 12
Now all we have to do is substitute 12 for a in any equation. For this I will use the first one.
12 + b = 8
Lastly subtract 12 from both sides
b = -4
Answer:
a = 6 , b = 2
Step-by-step explanation:
a+b - (a-b) = 2b
8 - 4 = 4
2b = 4
b = 4 ÷ 2
b = 2
When b = 2,
