Write an expression that, when simplified is equivalent to 15x +7

Answer:

A. 120(3)t = 3,240; t = 3

Step-by-step explanation:

We are given that enrollment capacity for first year = 120

The school plans to triple the capacity every year.

Assuming t to be the number of years, the capacity for every t year will be [tex]3^t[/tex].

This is expressed by the equation [tex]120(3)^t = 3240[/tex]

Substituting t =3 in the above equation to get:

[tex]120(3)^3 = 120\times 27=[/tex] 3240

So the equation is true when t = 3.

Therefore, the correct answer option is A. 120(3)t = 3,240; t = 3.

Step-by-step explanation:

Because the sugar tablets will do nothing to the patient, the reasearcher wants to see how the patient will act thinking that they are being treated with medication, when infact it is just a sugar tablet, he is trying to find out the psychological effect it will have on the patient, so the answer is E.

The sugar tablets devoid of any medical effects are most likely used as placebos in medical research. They serve as a control measure in drug trials to ensure any observed changes are attributed to the medication being tested and not from biases or expectations.

In the field of medical research, sugar tablets without any medical effects are likely used as placebos. Placebos are administered as control measures in experimental studies to ensure that any observed effects can be attributed to the medication being tested, rather than participant expectations or experimenter bias. For instance, in a drug trial, one group (the experimental group) receives the medication, while another group (the control group) receives a placebo, in this case, a sugar tablet. If the experimental group shows different results as compared to the control group, it can be deduced the differences are likely due to the drug itself. This process helps to maintain the integrity and credibility of medical research.

Answer:

eight cubes can be shipped.

Step-by-step explanation:

The height of the shipping box is the same as the height of the boxes that are about to be shipped. (4 1/2 inches). So you can get 1 layer of the boxes to be shipped.

The length of the shipping box is 18 inches. You will be able to get 18/4.5 = 4 boxes along the 18 inch side.

The 9 inch side will allow 2 boxes.

Answer:

300

Step-by-step explanation:

A number cube has total six possible outcomes:

1, 2, 3, 4, 5 and 6

Probability of the occurrence of each side is: 1/6

From the possible outcomes, the even number are 2,4,6

Therefore the probability of the occurrence of an even number is:

1/6 + 1/6 + 1/6

=> 3/6

=> 1/2

1/2 probability shows that if a number cube is rolled 'n' times, (1/2)*n number of chances are it is an even number.

So the expectation of rolling an even number with 600 trials is:

(1/2)*600

=> 300

To find out how much of the $13,000 was loaned at 8%, set up a system of equations based on the total amount of the loan and the total interest received. Solve the equations to find that $7,250 was loaned at an 8% interest rate.

Explanation:

The student is dealing with a problem related to the allocation of two different simple interest rates for portions of a loan. To find out how much was loaned at 8%, we set up two equations representing the amounts loaned at each rate and the total interest earned. Let's assume the amount loaned at 8% is x and the amount loaned at 16% is y. The following system of equations can be formed:

By solving this system of equations, we can determine the value of x and y.

The first step is to express y in terms of x from the first equation: y = 13000 - x. Next, we substitute this expression into the second equation: 0.08x + 0.16(13000 - x) = 1500. Simplifying this gives us 0.08x + 2080 - 0.16x = 1500, which further simplifies to -0.08x = -580. Dividing by -0.08, we find x = 7250. Therefore, $7,250 was loaned at 8%.

Answer:

D) d,c,a,b

Step-by-step explanation:

To arrange the fractions in the order requested we have to express them to a common denominator . This is done by finding the Least common multiple of the denominators. Thus, the fractions,7/3, 8/2, 2/1,6/5, the L.C.M of the denominators is 30 thus lets divide the L.C.M by the denominator of each number then multiply with the numerator.

7/3=70/30

8/2=120/30

2/1=60/30

6/5=36/30

thus from the least  to the largest we arrange them as follows 6/5, 2/1, 7/3 then 8/2

Answer:

[tex]\frac{50}{113}[/tex]

Step-by-step explanation:

The ratio is simply the division of one by another (and simplification).

Hence, the ratio of production of the first line to the second line is 1250 divided by 2825. So,

Ratio = [tex]\frac{1250}{2825}=\frac{50}{113}[/tex]

Answer:

[tex]\frac{50}{113}[/tex] or [tex]0.442[/tex]

Step-by-step explanation:

We are given that a plant runs two assembly lines, the first one produces 1,250 units a day while the second produces 2,825 units a day.

We are to find the ratio of production of the first line to the second line.

To find this production ratio, we would just simply divide the the production unit of first line with the production unit of the second line.

Ratio of production of the first line to the second line = [tex]\frac{1250}{2825}[/tex] = [tex]\frac{50}{113}[/tex] or [tex]0.442[/tex]

Answer:

The fraction of her stickers that are not animal or flower is [tex]\frac{9}{24}[/tex]

Step-by-step explanation:

Topic: Fractions

Let A represent the fraction of stickers that are animals

Let S represent the remaining stickers including the flower stickers

Given

A = [tex]\frac{5}{12}[/tex]

To get the fraction of stickers that are not animal or flower, the summation of the fraction must be equal to 1.

Mathematically, A + S = 1;

By Substitution, A + S = 1 becomes

[tex]\frac{5}{12} + S = 1[/tex] ------ Collect like terms

[tex]S = 1 - \frac{5}{12}[/tex]

[tex]S = \frac{12 - 5}{12}[/tex]

[tex]S = \frac{7}{12}[/tex]

Hence, the fraction of her stickers that are not animal is [tex]\frac{7}{12}[/tex]

From the question, we have that [tex]\frac{5}{14}[/tex] of the remainder are flower stickers.

Let F = Flower Stickers

F = [tex]\frac{5}{14}[/tex] * S

F = [tex]\frac{5}{14}[/tex] * [tex]\frac{7}{12}[/tex]

F = [tex]\frac{5}{2}[/tex] * [tex]\frac{1}{12}[/tex]

F = [tex]\frac{5}{24}[/tex]

To get the fraction of stickers that are not animal or flower, the summation of the fraction must be equal to 1.

Mathematically, A + F + R= 1;

R = 1 - A - F

Where R represent the fraction of stickers that are not animal or flower

[tex]R = 1 - \frac{5}{12} - \frac{5}{24}[/tex]

[tex]R = \frac{24 - 10 - 5}{24}[/tex]

[tex]R = \frac{9}{24}[/tex]

Hence, the fraction of her stickers that are not animal or flower is [tex]\frac{9}{24}[/tex]
