Answer:

Sofia would have the stronger orange flavor with the ratio being 4 to 8 while Sarah's ratio would be 3 to 9.  Sofia has the more orange flavor because she added 4 liters of it into her mixture while Sarah only added 3

If you need it to be explained further just let me know and I will put it in the comments, I try to make my answers as straightforward as possible. :)

Answer:

sarah's ratio - 3:9 / 1:3

sofia's ratio - 4:8 / 1:2

Step-by-step explanation:

i believe that sofia's sparkling orange juice (or whatever it is) is going to have the stronger orange taste because for every two liters of sparkling water she adds a liter or orange juice, whereas, sarah's is for every three liters of sparkling water she adds a liter of orange juice. sooooo sofia is most likely going to have the stronger orange flavor.

There are approximately 3,000 bass in a lake. The population grows at a rate of 2% per year. Round answers to the nearest tenth.

From Year 1 to Year 4, the average rate of change of the population was about 62.4 bass per year.

From Year 5 to Year 8, the average rate of change of the population was about 67.6 bass per year.

The rate of change increased by about _____ bass per a year.

Answers

Answer:

years 1–4: 62.4 bass per year

years 5–8: 67.6 bass per year

Step-by-step explanation:

If the population in year n is ...

 p(n) = 3000·1.02^n

then the average rate of change from year 1 to year 4 is ...

 (p(4) -p(1))/(4 -1) = 3000(1.02^4 -1.02^1)/3 = 1020·(1.02^3 -1) ≈ 62.4

The average rate of change for years 1–4 is 62.4 bass per year.

___

For years 5–8, the rate of change is similarly computed:

 (p(8) -p(5))/(8 -5) = 3000(1.02^8 -1.02^5)/3 = 1000·1.02^5·(1.02^3 -1) ≈ 67.6

The average rate of change for years 5–8 is 67.6 bass per year.

An online survey revealed that 78% of the people liked to listen to music in the car. If 234 people said that they like to listen to music in the car, how many people total were surveyed?

Answers

The total amount of people that were surveyed were 300 people.

Explanation: Divide 234 by 78 and you should get what the one percent is. Then multiple that by 100.
300 people. this is because you would divide 234 by 78 (equals 3) then, multiple by 100 (equals 300)

A line is reflected, what line is the results?

Answers

Answer:

A I think

Step-by-step explanation:

I dont really get the question so im not sure

Answer:

C.

Step-by-step explanation:

The question states that a LINE is reflected, just with this information we know that A. is incorrect because it is curved.

At first, when looking at B., it seems as though it could work, until you notice that it starts somewhere, but doesn't end, thus it is not a LINE. So, we can count B as incorrect as well.

When looking at C, it it a straight line, and has a beginning and and end, which means that so far, it is the most likely the line.

Then, we look at D. When looking at D, we can tell that it is a straight line, however, it has no beginning and no end, thus it can't be the answer.

Now, we know that C is the only possible answer for this question.

Answers

Answer:

f(x) = -(x-3)^2 + 4

Step-by-step explanation:

(h; k) are the coordinates of the vertex.

On the graph are (3, 4), therefore we have:

f(x) = a(x-3)^2 + 4

We have the x- intercept (1,0) -> x=1; y=0.

Substitute them into the equation:

0 = a(1 - 3)^2 + 4

0 = a(-2)^2 + 4

4a + 4 = 0 | -4

4a = -4   |-4

a = -1

So, we have the answer:

f(x) = -(x-3)^2 + 4

Subtract

Aiden says that equivalent expressions always have the same number of terms. Is Aiden correct? If he is, explain why. If he is not correct, give a counterexample.

Answers

No. Because for example

4+5 is 9, which has 2 terms (4,5)
BUT
3+5+1 also equals 9, which has 3 terms (3,5,1)

Both equations are equivalent to eachother, but do not have the same amount of terms. This also goes for multiplication.

10x10 is 100, which has 2 terms

BUT

5x10x2 is also 100, which has 3 terms, therefor the answer does not determine the amount of terms in an equation.

The opinion of Aiden about equivalent expressions always having the same number of terms is; Not correct

Mathematical Operations

Aiden is not correct with his assertion as we will see for four major operations.

1) Addition; 2 + 6 = 8 and also 1 + 3 + 4 = 8.

We can see that in both cases the expressions have equivalent answers but the number of terms are not the same.

2) In multiplication; 2 × 6 = 12 and also 1 × 3 × 4 = 12. We can see that in both cases the expressions have equivalent answers but the number of terms are not the same.

Same scenario also applies for division and subtraction. Thus, we can say that Aiden is not correct.
