The area of the postcard pictured below is 24 square inches. What is the width b of the message section (in inches)? Pick the equation that would best model this situation.
A. 4(b + 3) = 24
B. 3(4 + b) = 24
C. 4(b - 3) = 24
D. 3(b - 4) = 24

The Area Of The Postcard Pictured Below Is 24 Square Inches. What Is The Width B Of The Message Section

Answers

Answer 1

Answer:

Step-by-step explanation:

4(b + 3) = 24

Answer 2

Answer:

A. 24 = 4(b + 3)

Step-by-step explanation:

Area is equal to length times width. In this case, the length is b + 3 (since both b and 3 are part of the width, with the length being 4.

Substitute into the equation for area:

a = lw

a = 4(b + 3)

The area is 24, so the final answer is:

A. 24 = 4(b + 3)

You need a 45% alcohol solution. On hand, you have a 175 mL of a 25% alcohol mixture. You also have 70% alcohol mixture. How much of the 70% mixture will you need to add to obtain the desired solution?

Answers

175 mL at 25% concentration of alcohol contains 0.25 (175 mL) = 43.75 mL of alcohol. If v is the amount of the 70% solution that you use, then that amount contains 0.7v mL of alcohol.

Mixing these two yields a total volume of 175 mL + v, and it contains 43.75 mL + 0.7v alcohol. You want to end up with a concentration of 45%, which means the ratio of the amount of alcohol to the total volume needs to be 0.45:

(43.75 mL + 0.7v) / (175 mL + v) = 0.45

Solve for v :

43.75 mL + 0.7v = 0.45 (175 mL + v)

43.75 mL + 0.7v = 78.75 mL + 0.45v

0.25v = 35 mL

v = 140 mL

Where,

a = 6

b = x = ?

c = 15

Plug in the values into the equation

1,500 divided by 8 step by step

Answers

Answer:

1500 divided by 8 = 187.5

Step-by-step explanation:

1,500 divided by 8 is equal to 187, with the remainder of 4.

To divide 1,500 by 8 step by step, we can follow the long division method.

We start by dividing the first digit of the dividend (1) by the divisor (8). Since 1 is smaller than 8, we move to the next digit of the dividend.

We bring down the next digit of the dividend (5) and divide 15 by 8. The quotient is 1, and the remainder is 7.

8 ) 1,500 ( 187R4

A pump removes 1500 gal of water from a pool at a constant rate 40 gal/min. Which equation models the amount of water y in the pool after t minutes?


A. y = 40t + 1500


B. y = -40t - 1500

C. y = 40t - 1500

D. y = -40t + 1500

Answers

D, y=-40t+1500

You are subtracting 40 gallons each minute, which is why this is negative. The 1500 is positive, since this is what you have initially, and are subtracting from.

A box has 18 candies in it: 3 are peppermint, 4 are caramel, and 11 are taffy. Jina wants to select two candies to eat for dessert. The first candy will be selected at random, and then the second candy will be selected at random from the remaining candies. What is the probability that the first candy selected is caramel and the second candy is taffy? Do not round your intermediate computations. Round your final answer to three decimal places.

Answers

11/18 = 0.61111111 (continuing)

3/18 = 0.166666 (continuing)

4/18 = 0.222222(continuing)

caramel = 0.2222222 x taffy = 0.6111111111

probability = 0.1358024691358, 0.136.

13.6%

The probability that the first candy selected is caramel and the second candy is taffy is 0.175

What is probability?

Probablity is the likelihood or chance that an event will occur.

Probability = expected/total

If a box has 18 candies in it, the total outcome will be 18

If the probability that the first candy selected is caramel is 4/18

If the probability that the second candy selected is randy is 11/18

Pr(caramel and randy) = 4/18 * 11/18

Pr(caramel and randy) = 2/9* 11/18
Pr(caramel and randy) = 11/63

Hence the probability that the first candy selected is caramel and the second candy is taffy is 0.175

Two lines are parallel, but are not the same line. Which of the following is not true of the lines? A. The slopes are the same. B. The lines have no points in common. C. The y-intercepts are not the same. D. The lines must have a positive slope. Please select the best answer from the choices provided A B C D

Answers

Answer:

D

Step-by-step explanation:

Parallel lines must have the same slope. They could have points in common. If the y-intercepts were the same, taking into consideration the fact that the slopes have to be the same, it would be the same line and as the question directs, they are not. Parallel lines can have negative slope, as long as their slopes are equal.

Answers

Answer:   Choice A)  -20+48i

========================================

Work Shown:

x = (4+6i)(4+6i)

x = y(4+6i)  ...... let y = 4+6i

x = 4(y)+6i(y)  ..... distribute

x = 4(4+6i)+6i(4+6i)  .... plug in y = 4+6i

x = 16+24i+24i+36i^2  ..... distribute again

x = 16+24i+24i+36(-1)  .... use the fact that i^2 = -1

x = 16+24i+24i-36

x = 16-36+24i+24i

How is this couple practicing healthy communication? Check all that apply. Is unflavored Gelatin a natural resource???!ANSWER NEEDED QUICKLY!!! THANK YOU! Hi, can someone help me revise with the following PIE paragraphs I need help with grammar puntuatuion. I would like if you can help me add or take some setences if does not make sense thank you!!Problem, Cause, and Solution PIE Paragraphs One of the systemic education problems is that the financial aid system doesnt offer financial help to students. For example, When students doesnt recive financial help they are just worry about how they going to pay for their tuition. When they dont have money to pay for they tuition they might thinking in not continue with school. In the memoir Educated, Tara Westover had this problem when she first started school at Brigham Young University. Westover (2018) wrote, My bank account decreased steadily, I had been worried that I might not pass my classes, but a month into the semester, after Id paid tuition and rent and bought food and books, I began to think that even if I pass I wouldnt be coming back to school for one obvious reason: I couldnt afford it (p. 239). Westover said that she might not continue with school because she doesnt have enough money to pay her rent and her tuition. If financial aid provides her help, she might not be thinking in leave the shcool. This concludes that the financial help system is a big problem with students education.The first cause of this problem comes from student parent income. Financial aid offer financial help to students based on they parent income. The financial aid system assumes that a if a student parent income is high enough they will be able to cover their son or doughter tuition. For example, I have a friend who was studying at Skagit valley college she couldnt qualified for financial aid because her parents income was too high. Financial aid thought that her parent would help her because their income was high enough. What financial did not know is that her parent wouldnt help her pay for college tuition. This leads her to stop with her education and looks for work so she can save money to pay for college.The second, cause is that they are hard on the requirement. Financial aid require students to be a full time student in order to qualify for financial aid. When financial aid require student to take 3 classes, they can not learn all the material that they are studying When student take more than three classes, they can not learn what they are studying because is too much for their brain. For example in A Glossary of Common Lerning Terms. John Websters ( 2020) wrote, Our brains work easily with a few concepts or numbers at once, but when we work with more than three to five entities the load begins to get heavy. This what happened to student when the financial aid require them to take three classes. When student take three classes it is difficul for them to learn all the three subject they are studying. Their brain cant process well all the information they are learning. This leads to a bad GPA at the end of the quarter because they did not perform well on the assignment because it was too much information for their brain. First solution is that financial aid should not offer financial aid help base on students parent income. Not all parent help their son or daughter to pay for college. For example as I mention before my friend parent didnt help her to pay for her college tuition. Even her parent income was high they didnt help her to pay for her college tuition. This is what many student face todays their parent income does not have nothing to do with them. For this reason financial aid should not focus on student parent income in order to offer them financial aid. Financial aid system should help students independently not base on their parent income.A solution to financial aid system problem is to change the hard requirement that they have on students. For example the financial aid should provide financial aid for part time students and not just for full time students. If financial aid dont change their requirement, students are more likely are more to not continue with their education. For example, one of my other frind coldnt qualified for financial aid because she was a part time students. Since she couldnt qualified for financial aid she stop attending college. The last time I talk with her she told me that she might not come back to college because she work and she can not be a full time student. For For this reason, financial aid needs to change the hard requirement and be able to help all students no matter if they are part time or full time students by doing this financial aid will help students to achieve their goals.
