Option B.             The ratio of the number of students who passed the test to

the total number of students who took the test is 2/3

Step-by-step explanation:

Firstly, we have to find the total number of students who took the test, we can do that by adding the number of students who passed and the number of students who did not pass, so ...

32 + 16 = 48

Now we just write down the ratio between the number of students who passed the test and  the total number of students who took the test. So we get

32/48

Now we just simplify and get...

2/3

Answer:

The answer is 16/3.

$113.28 is the total cost

Step-by-step explanation:

18%= 0.18

96 x 0.18= $17.28

96 + 17.28= $113.28

Answer:

1. Skyler's processes are incorrect. She put (3^6)^x = 9, but when working with exponential problems, both sides have to have the same base. 3 does not equal nine, so you can automatically rule out her approach.

2. Robert's processes are correct. He set both bases equal to each other and then solved for the exponents.

3. Kaitlyn is also correct, she set the bases equal to 3 and solved for the exponents.

Step-by-step explanation:

When working with exponents, the goal is to get the bases equal to each other. In this case, you could have set it equal to 9 (which Robert did) or you could have set it equal to 3 (like Kaitlyn did). But you never want the bases to be conflicting, which is what Skyler did. Just by looking at the problem and using deductive reasoning, it is likely that Robert and Kaitlyn are both correct, since they have the same answers, although they used different methods, but it is still important to look at the steps.

Skyler's one mistake was setting 3 = 9, because that is impossible. If you plug in her answer of 3/2 into x, you get a ridiculous number of 19,683 = 9, which is not possibly true. For the others, when you plug in 1/3, you get 729^(1/3) = 9, so 9=9.

Hopefully this makes sense, if not, I can try to explain it better. Thanks much & have a wonderful day.

The explanation of whether Skyler, Robert or Kaitlyn were correct/wrong and the reason from their processes is that;

1) Skyler is wrong because she didn't make the bases of both sides to be equal before equating the exponents.

2) Robert is correct because he made the bases of both sides to be the same before equating the exponents.

3) Kaitlyn is correct because she made the bases of both sides to be the same before equating the exponents.

The problem skyler wants to solve is;

729^(x) = 9

The first step is to reduce 729 to the lowest base to get; [3^(6)]^(x) = 9

Next she did was to equate 6x to 9.

When working with equality of exponents both sides ought to have the same base and so she could have converted 9 to have same base of 3 as the left hand side after which she will equate the exponents.

So skyler is wrong.

We saw that skyler didn'take both bases equal to each other but now Robert has done the correct thing by having;

9^(3x) = 9¹

After which he equated the exponents to get;

3x = 1

x = 1/3

Thus; Robert is correct

Kaitlyn is also correct because she followed the same correct pattern of ensuring the bases are the same before equating their exponents.

[tex]Selling\ Price = 12b(1.55)[/tex]

Step-by-step explanation:

Given

[tex]Cost\ Price = \$12[/tex]

[tex]Selling\ Price = 55\%\ more[/tex]

Required

Write an expression for the selling price for b birdbaths

This selling price for 1 birdbath is calculated as:

[tex]Selling\ Price = Cost\ Price + 55\% * Cost\ Price[/tex]

Substitute 12 for Cost Price

[tex]Selling\ Price = 12 + 55\% * 12[/tex]

Factorize:

[tex]Selling\ Price = 12(1 + 55\%)[/tex]

Express percentage as decimal

[tex]Selling\ Price = 12(1 + 0.55)[/tex]

[tex]Selling\ Price = 12(1.55)[/tex]

For b birdbaths, the selling price is:

[tex]Selling\ Price = 12(1.55) * b[/tex]

[tex]Selling\ Price = 12b(1.55)[/tex]

The options are not clear; However [tex]12b(1.55)[/tex] answers the question.

Answer:

5 hours

Step-by-step explanation:

If he drove 360 miles in 6 hours, that means he drives 60 miles per hour.

300 divided by 60 is 5, so he will need to drive for 5 more hours

Answer:

5 hours

Step-by-step explanation:

Find his speed in miles per hour:

360/6

= 60

So, his speed is 60 mph

To find how many more hours he would have to drive another 300 miles, divide 300 by 60:

300/60

= 5

So, he would have to drive 5 hours

[tex]\frac{29}{50}[/tex]

Step-by-step explanation:

We have two fractions and are being asked to add them both.

5/10 and 8/100 don't have the fractions, but 5/10 can be simplified to 1/2, meaning that to make the same denominator, we have to find the half of 100, which would be 50. Now turn the fraction into 50/100.

50/100 + 8/100

58/100

This can be simplifed :
