marilyns teacher slowed her to take a makeup test she scored 24/60 on the original test and 28/40 on the makeup test by what percentage did marilyn improve her score

Answers

Answer 1
First test: 24/60 = 0.4 = 40%
Second test: 28/40 = 0.7 = 70%

So you could say 30% improvement, but if the way it’s worded makes me wonder if they want to know what percentage of 40 is 70.

0.4x = 0.7
0.7/0.4 = x
x = 1.75 = 175%

Which one sounds more like what you’re learning in class right now? That’s the answer I would go with.

What is the inverse function (equation) of f(x) = 6x - 5 ?

Answers

Step-by-step explanation:

Given

f(x) = 6x - 5

f^-1(x) = ?

Let

y = f(x)

y = 6x - 5

Interchanging the roles of x and y we get

x = 6y - 5

6y = x + 5

y = ( x + 5 ) / 6

So therefore f^- 1(x) = (x + 5) / 6

A rectangular chocolate bar is made of equal squares. Irena breaks off two complete strips of squares and eats the 12 squares she obtains. Later, Jack breaks off one complete strip of squares from the same bar and eats the 9 squares he obtains. How many squares of chocolate are left in the bar?

Answers

Answer:

There are three more square chocolates left

Step-by-step explanation:

We know that Irena breaks off 2 complete strips and eats 12 meaning each strip had 6 squares. Jack breaks off 9. So if we add all the squares into rows of 6, we get four strips of chocolate from the beginning. Since Jack and Irena obtained 21 chocolate squares altogether, we have 3 chocolate squares that are remaining. I hope this helps ;)

The number of Squares of chocolate left in the bar is; 15 squares

What is the amount of squares left?

A square has 4 equal sides and since one row contains 6 squares because irena ate 2 complete rows that had 12 squares.

It means that each of the vertical height must also contain 6 squares as well.

Now, two rows are gone and so we now have 4 rows with vertical height of 4 squares. That is 24 squares left.

Now, Jack ate 9 squares and so;

Amount of squares left = 25 - 9 = 15

four thousand three hundred twenty-one ten thousandths as a decimal​

Answers

Answer:

.4321

Step-by-step explanation:

move the decimal to the left four times

We want to write four thousand three hundred twenty-one ten thousandths as a decimal​.

The number is:

4321.010

To do it, we need to understand what each place value represents, where the place values are the place of each digit in reference to the decimal point.

The first digit at the left of the decimal point represents the units.The second digit at the left of the decimal point represents the tens.The third digit at the left of the decimal point represents the hundreds.The fourth digit at the left of the decimal point represents the thousands.

And for the right we have:

The first digit at the right of the decimal point represents the tenths.The second digit at the right of the decimal point represents the hundredths.The third represents the thousandths.

Of course, it continues in both ways, but this is enough to write our number.

We have:

"four thousand..."

Then the fourth digit at the left is a 4.

"... three hundred..."

The third digit is a 3.

"...twenty-one..."

The second digit is a 2, and the first is a 1.

For the right side, we do not have tenths, so the first digit at the right is a zero.

And "...ten thousandths"

We have a "10" in the second and third digits at the right of the decimal point.

Then our number is:

4321.010

Suzanne, Latisha, and Morgan measure their heights. Suzanna is 0.8 times the height of Latisha, and Morgan is 1.09 times the height of Latisha. Who is the tallest? Who is the shortest?

Answers

Answer:

Tallest = Morgan

Shortest = Suzanna

Step-by-step explanation:

Assuming Latisha = 1

0.8 is less than 1, meaning it's 80% the height of Latisha, so this means Suzanna is shorter than Latisha.

1.09 is more than 1, Morgan is taller than Latisha.

Morgan is tallest and Suzanna is shortest, Latisha in the middle.

Answers

Answer:

7.9 m

Step-by-step explanation:

Use the Pythagorean theorem: a²+b²=c²

This formula can be used to solve a side of any right (90°) triangle.

c² is the length of the hypotenuse (the diagonal side of the triangle, opposite to the 90° angle)

So, c = 32m.

Sides a and b are the legs of the triangle, but we only know one side. Plug numbers into the formula:

31² + b² = 32²

961 + b² = 1024 Subtract 961 from both sides to get b² by itself.

b² = 63

√b² = √63  Square root both sides to get b by itself.

b = 7.93725

Answer is 7.9 meters, rounded to tenths place
