A-The answer must be less than 5/6.
B-The answer cannot be an improper fraction.
C-5/6 of a number cannot be greater than the number.
D-The denominator cannot be the same as one of the factors.

Answer 1
Answer:

Answer:

The answer is 25/18, not 7/3.

Step-by-step explanation:

1 2/3=5/3

5/6*5/3=25/18
Answer 2
Answer:

Answer:

C-5/6 of a number cannot be greater than the number.

Step-by-step explanation:

5/6 × 1 2/3 is 7/3.

First let's solve it:

  • Convert 1 2/3 to an improper fraction

1 2/3 = (1 *3) + 2 / 3 = 5/3

  • Multiply the fractions

5/6 × 5/3 = 25/18

A is wrong because the answer is not less than 5.6

B is wrong because the answer is an improper fraction.

D is wrong because the denominator is the same as one of the factors.

Therefore it has to be C.

2/3 * 1 = 2/3

Therefore how can 5/6, which is less than 1, multiply by 2/3 and get a greater answer.

Which expression could be used to solve this problem?Bart practices piano every day. First he practices songs for 20 minutes. Then he practices scales for 15 minutes. How much time does Bart practice piano in 3 days?


A.
3 × (20 – 15)

B.
20 × (15 + 3)

C.
3 × (20 + 15)

D.
20 × (15 – 3)

Answers

Answer:

C. 3 × (20 + 15)

Step-by-step explanation:

If Ben practices this way every day, then the amount of time should be the same.

20 minutes of song practice, 15 minutes of scale practice.

20+15=35

multiply the 35 minutes per day by three

35 times 3 equals 105

So the answer is C.

3 × (20 + 15)

3(35)=105

Answer:

C. 3 x (20 + 15)

Step-by-step explanation:

You have to add 20 + 15 to get 45 so the 20 + 15 goes in the (). It says how much time he has practiced in 3 days so you have to multiply the things in the () by 3 so the 3 goes out side the ().

only 6 of the 75 trees in the park are at leat 30 feet tall. what percent of the trees are over 30 feet?

Answers

Answer:

   8 %

Step-by-step explanation:

To find the percent of trees that are over 30 ft tall, take the number of trees that are over 30 ft tall over the number of tree

Percent = trees over 30 ft tall/ total number of trees

              = 6/75

              =.08

Change this to a percent by multiply by 100%

             .08 * 100%

                    8 %

An apple is cut into 6 equal slices. Nancy eats 2 of the slices. What fraction of the Apple is left?

Answers

The answer is:
2/6
6-2=4
4/6=2/3
Cut the apple into pieces. You get 6/6, which is equal to 1 whole apple. Then after Nancy eats 2 of the slices, you subtract 2/6 from 6/6. After this you get 4/6.

4/6 is the fraction of the apple is left.

Drag the orange point on the cube to change its side length. Then set the base of the pyramid to the same dimensions as a face on the cube. Also set the height of the pyramid to the same side length as the cube. Note the volumes of the cube and the pyramid. Record the volumes for a few sets of heights and bases, and then calculate the ratio of the volumes. Be sure the dimensions for the cube and the pyramid are the same in each set. (You might see some discrepancies in the tool due to rounding of decimals.) Round your calculations for the ratio to the hundredths place. The first one has been done for you.

Determine the equation of the line with slope 3 that passes through the point M(1.2).
?

Answers

y = 3x - 1

The format for slope intercept form is:

y = mx + b

m represents the slope and that was given so:

y = 3x + b

Now we have to substitute the value from the given point into “y” and “x” to solve for “b”

(2) = 3(1) + b
2 = 3 + b
-1 = b

Now that we know b we can substitute it into y = 3x + b to get the equation of the line

y = 3x - 1
