priya bought x grams of flour Clara bought 3/8 more than that select all questions that represent the relationship between the amount of flour prior bought x and the amount of flour Clara bought is y

a. y = 3/7 c
b. y = 5/8 x
c.y = x + 3/8 x
d. y= x - 3/8 x
e. y = 11/8 x​

Answers

Answer:

Option C : [tex]x+\frac{3}{8}x[/tex] is the correct answer.

Step-by-step explanation:

Given that:

Quantity of flour bought by Priya = x grams

Quantity of flour bought by Clara = 3/8 more than that

It means that Clara bought the amount bought by Priya plus an additional 3/8 of flour that was bought by Priya

Total bought = y

y = x + [tex]\frac{3}{8}x[/tex]

Hence,

Option C : [tex]x+\frac{3}{8}x[/tex] is the correct answer.

A family has 4 horses bred from the same set of parents. All of their horses are mares (females). They are planning on having one more horse to complete their herd. A neighbor comments that they are much more likely to end up with a male horse the next time around. Is the neighbor’s reasoning correct?
a. Yes, they are more likely to end up with a male horse in order for the probabilities of male and female to get back to 0.5
b. No, the probability of the new horse being male or female remains 0.5, regardless of what its older siblings are.
c. Yes, after having so many female horses in a row, the breeding pair is due to have a male.

Mary draws the number line below to represent the solution set of the inequality 50 – 8t < 90. What mistake did Mary make? Use the drop-down menus to explain your answer.

Answers

Picture relating to question is attached below

Answer:

t > - 5

Line is in the wrong side

Step-by-step explanation:

Given the inequality :

50 – 8t < 90

-8t < 90 - 50

-8t < 40

-8t / - 8 < (40/ - 8)

t > - 5 (sign changes)

During simplification, we should observe that the inequality sign changes due to negative sign. Hence, our final inequality equation read t > - 5 ; thus, arrow should point to the right

Answers

Answer:

20/8 or 5/2

Step-by-step explanation:

4 can be written as 4/1, and 5/8 is just 5/8.

5/2 is the solution.

4/1 • 5/8 = 20/8, simplified it is 5/2.

Someone please help me with this question I'm struggling

Answers

ExplanationSolve for x-term when g(x) = 5. Substitute g(x) = 5 in the equation.

[tex]g(x) = - 2x + 1 \\ 5 = - 2x + 1[/tex]

Solve for the x-term.

[tex]2x = - 5 + 1 \\ 2x = - 4 \\ x = \frac{ - 4}{2} \\ x = \frac{ \cancel{ - 4} \: \: \: - 2}{ \cancel{2} \: \: \: 1} \Longrightarrow \: \frac{ - 2}{1} \\ x = - 2[/tex]

Answer Check

Substitute x = -2 in the equation.

[tex]5 = - 2( - 2) + 1 \\ 5 = 4 + 1 \\ 5 = 5[/tex]

The equation is true. Therefore x = -2 is the answer.

A skin care company had 1,500 people try a new acne cream. Nine people had a mild reaction the formula is then improved and those 1,500 people try the new cream only 4

Answers

Answer:

The percent decrease in number of allergic reactions is 55%

Step-by-step explanation:

Only 4 of them had a mild allergic reaction. What is the percent decrease in number of allergic reactions?

Percent of allergic people= Allergic people/ Total people * 100

                                         = 9/1500* 100

                                         = 0.6 %

IT means that out of 1000 people only 6 persons are allergic to the cream.

New Percent of allergic people= Allergic people/ Total people * 100

                                         = 4/1500* 100

                                         = 0.267 %

It means that out of 1000 people only 2.67 persons are allergic to the new improved cream.

Difference between Percentage = Old Percentage- New Percentage

                                                      = 0.6 %- 0.267%

                                                       =0.333%

Decrease= 0.333% = 0.333/100

In every thousand people 3.33 people are free of allergic reactions from those 6 allergic people.

Percentage Decrease= Decrease/ Total * 100

                        = 0.333/ 0.6 *100

                           = 0.55*100

                            = 55 %

The percent decrease in number of allergic reactions is 55%

Answers

Answer:

I two groups are formed: 18 students

If 3 groups are formed: 12 students

Step-by-step explanation:

We will answer this problem based on two occurrences:

1. The students chose to form only two groups:

If the students chose to form only two groups, the number of students in each group will be got by dividing the total number of students by 2. this will be 36/2 = 18. Therefore, there will be 18 students per group if only 2 groups were formed.

2. The students chose to form three groups:

If the students chose to form three groups, we will divide the total number of students by 3. this will be 36/3 = 12. Therefore, there will be 12 students per group if only 3 groups were formed.
