Use the number line below, where RS=9y+2, ST=2y+6, and RT= 52

Answers

Answer:

Step-by-step explanation:

Given

RS=9y+2, ST=2y+6, and RT= 52

The addition postulate is true for the number line.

RS+ST = RT

Substitute

9y+2+(2y+6) = 52

9y+2y+8 = 52

11y = 52-8

11y = 44

y = 44/11

y = 4

Find RS

RS = 9y+2

RS = 9(4)+2

RS = 36+2

RS = 38

Find ST:

ST = 2y+6

ST = 2(4)+6

ST = 8+6

ST = 14

Hence y = 4, RS = 38 and ST = 14

Simon bought three plants at a nursery for 17.94 how hutch money would it cost for Simon to go back to the store and buy two more plants. Please help me !

Answers

Answer:

11-96

Step-by-step explanation:

The money required for Simon to buy two more plants is 11.96

What is Average?

The average value in a set of numbers is the middle value, calculated by dividing the total of all the values by the number of values.

Given data ,

Number of plants Simon bought = 3 plants

Total amount of plants = 17.94

Amount for one plant = Total amount of plants / Number of plants bought

So , Amount for one plant = 17.94 / 3

                                           = 5.98

Therefore , Amount of cost for Simon to buy two more plants = Amount of one plant x 5.98

= 5.98 x 2

= 11.96

Hence , The money required for Simon to buy two more plants is 11.96

O C. 4.32891789376287184... and 0.2323
O D. 8.3182706837521... and 0.232323...

Answers

Answer:

A. 0.752 and 0.232323...

Step-by-step explanation:

A rational number is a number that can be expressed as a ratio. That is, it can be written as a quotient of two integers. A rational number can have a terminating decimal. E.g. 0.5, which can be expressed as ½ or 1:2. This is a terminating decimal. Also, a rational number could be a number that has repeating decimal that keeps repeating forever. E.g. 0.333... which can be expressed as ⅓, or 1:3.

An irrational number is just the opposite of a rational number. Thus, am irrational number cannot be expressed as ratio, and also has a decimal that goes on forever without repeating. For example, π = 22/7 = 3.14159... it has no definite ratio.

From these explanation we can easily pick out which pair that has both decimals representing rational numbers.

Thus, the answer is A. 0.752 and 0.232323...

0.752 is a terminating decimal, therefore it is a rational number.

0.232323... is a non-terminating decimal, however, its decimal is a repeating decimal. Therefore, it is a rational number.

Answer:

The answer is A 0.725 and 0.232323...

Tyler earned 60 points on his last test. If there were 75 possible points, what was his percent grade?

Answers

Answer:

his percent grade was 80

Step-by-step explanation:

15 is 20 percent of 75

This is a proportion problem. Eric earned 60 out of a possible 75 points, so the ratio is 60/75. You put that equal to x, so 60=x% and 75=100%. So it would look like

60 = x

75 100

then you cross multiply 60 and 100, and 75 and x, so you get

6000=75x

then divide by 75 and you have your percent

You change a fraction into a percentage by multiplying by 100.

So, for example, half is 1/2. Multiply by 100 gives 100/2=50. So half is 50%.

5. Ed, an employee of the Natural Color Company, suffered from a rare disease that was very expensive to treat. The local media ran several stories about Ed’s problems, and the family created a website that generated more than $10,000 in gifts from individuals to help pay the medical bills. Ed’s employer provided hospital and medical insurance for its employees, but the policy did not cover Ed’s illness. When it became apparent that Ed could not pay all of his medical expenses, the hospital canceled the $25,000 Ed owed at the time of his death. After Ed’s death, his former employer paid Ed’s widow $12,000 in "her time of need." Ed’s widow also collected $50,000 on a group term life insurance policy paid for by Ed’s employer. What are Ed’s and his widow’s gross income?

Answers

Answer:

$0

Step-by-step explanation:

The $10,000 that Ed's family received as gifts from individuals to help them pay the hospital bill are not included as part of their gross income.

Generally debt cancellations are taxable, except when they are made out of "detached and disinterested generosity", i.e. debt is cancelled for humane reasons and not business reasons. I believe that the $25,000 debt that was cancelled by the hospital fits into the definition of disinterested generosity, therefore, the $25,000 are considered a gift and are not taxable.

Under section 102, money given by an employer to an employee's widow may be considered a gift and is not taxable. If the payment is made due to a special circumstance and not in recognition of previous work done, then it is a gift. I also believe that the family can argue that this money is a gift since Ed died of a rare disease that left them almost bankrupt.

Life insurance proceeds are not taxable.

Listed below are the 35 members of the Metro Toledo Automobile Dealers Association. We would like to estimate the mean revenue from dealer service departments. The members are identified by numbering them 00 through 34.

Answers

Answer:

Metro Toledo Automobile Dealers Association

a) The mean revenue

= Total Revenue from the dealer service departments/35

b) The sample of five include 27, 23, 32, 11,  and 13

c) Using systematic random sampling, the dealers included in the sample are: 7, 13, 19, 25, and 31.

Step-by-step explanation:

a) The mean value is the total value divided by the number of elements. The mean revenue is, therefore, the total revenue from the dealer service departments divided by the number of dealers.  This gives an average revenue from each dealer, which is a statistic to describe the population.

b) The sample of five cannot include any number that is outside the population.  For example, 85 is not a number allocated to any dealer in the indicated population, therefore, it cannot form part of the population sample.

c) The systematic random sampling starts from 7 and chooses the sixth number after 7.  Therefore, the next four numbers are multiples of 6.  This is why we choose 13, 19, 25, and 31.
