Start the number line from 0 and put divisions at 1/12. Then mark at 4/12 for plant A and indicate this was its growth in the first week. Then, make another mark up to 6/12 and indicate this was the plant's growth in the second week.
For plant B, make one mark at 7/12 and indicate that this is plant B's growth in the first week.

After two weeks, plant A has a height of 6/12 inches and plant B has a height of 7/12 inches, so B is taller.

Simon fills a container with 38 1-in, cubes.
DanielleElmas [232]

<u>Question Correction</u>

Simon fills a container with 38 1-in, cubes. The container is a box of dimension 4 in. by 3 in. by 4 in.,How many more 1 in cubes does the container need to  be completely filled?

Answer:

10 1-in cubes

Step-by-step explanation:

First, we determine the Volume of the box.

Volume of a Rectangular Prism =Length X Height X Width

Volume of the box = 4 X 3 X 4= 48 cubic inches

To fill the box container, we would need 48 1 in cubes.

Since Simon already filled the container with 38 1-in, cubes.

Number of 1-in. cubes required to fill the box

=48 -38

=10.

Simon would need 10 1-in cubes to fill the box.

42/4 as a whole or mixed number and in simplified form
AlekseyPX

Answer:

10.5

Step-by-step explanation:

42/4 can be reduced by dividing numerator and denominator by 2:  21/2.

This is an improper fraction.  One way to obtain the equivalent mixed number would be to multiply numerator and denominator of 21/2 by 5, obtaining 105/10, which reuces to 10.5.

We could also divide 42 by 4 in the usual way, obtaining 10.5.

Explain the different ways that you can use multiplication to estimate and solve division problem
oee [108]

if I read your question correctly, you can use multiplication to get the same answer with division. for example;

 2 x 2 = 4;  4 divided by 2 = 2.

 8 x 4 = 32;  32 divided by 8 = 4;  32 divided by 4 = 8.

5 x 6 = 30;  30 divided by 5 = 6;  30 divided by 6 = 5

hope this helped! :D

What is the scale factor used to create this dilation?
alex41 [277]

The answer is: -1/5 or -0.2

One side of the original triangle is 15 units long and the side of the equivalent side of the dilated triangle is 3 units long. Therefore the magnitude of the enlargement scale factor is 3/15 or 1/5;

The answer is -1/5 as the transformation resulted in an inversion as well as an enlargement/dilation, therefore the answer is negative.
