Answers

Answer 1

Answer: the answer is 6 because it is the only number other than 2 that u can divide all of these numbers by... I would assume that your teacher wouldn't take 2 as an answer. 6/54=9
6/24=4
6/18=3

Explain how to use a tape diagram to find 90% of 180

Answers

Using a tape diagram, we find that 90% of 180 is 162.

A tape diagram, also known as a bar model, is a visual representation used to solve mathematical problems. To find 90% of 180 using a tape diagram, follow these steps:

Step 1: Draw a tape diagram with a bar that represents the whole value, which is 180 in this case.

Step 2: Divide the bar into 10 equal segments, representing 100% of the value.

Step 3: Shade 9 out of the 10 segments to represent 90% of the value.

Step 4: Determine the value represented by the shaded segments. Since 9 out of 10 segments are shaded, the value is 9/10 of 180.

Step 5: Calculate the result. 9/10 of 180 is (9/10) * 180 = 162.

Therefore, using a tape diagram, we find that 90% of 180 is 162. This visual representation helps understand the concept of percentages and provides an intuitive way to solve the problem.

You must make a tape diagram going by 10 percents. 10, 20, 30... Then, put 180 over the 90 percent. Then, do 180 divide by 10 to find out 10 percent. That is 18. Then do 18 times 9 which is 162.

Also, you could make 90 a decimal. 0.90. 0.90 times 180 is 162.

you have three numbers two of the numbers are 24 and 42 what is the gfc of these two numbers the third number is greater than 42 and does not change the gcf. What is one possibility for the third number?

Answers

Try 30 because 24 and 42 are both factors of 6 and so is 30 and since 6*5 is 30, it does not change the gcf

Final answer:

The Greatest Common Factor of 24 and 42 is 6. A possible third number that would not change the GCF and is greater than 42 could be 48, as 6 still divides it exactly.

Explanation:

In mathematics, the question discusses finding the Greatest Common Factor (GCF) of two numbers, 24 and 42. The GCF is the highest number that divides exactly into both numbers. If you factorize 24 and 42, you find that the highest factor they share in common is 6. So, the GCF of 24 and 42 is 6.

Moving on, the third number that does not affect the GCF could be any number that is greater than 42 and has 6 as a factor. So, a possibility could be 48, because 48 is greater than 42, and the GCF of 6, 24, and 48 remains 6.

Hannah has a grid of squares that had 12 rows with 15 squares in each row. She colors 5 rows of 8 squares in the middle of the grid blue. She colors the rest of the squares red. How many squares does Hannah color red?

Answers

there's a grid of squares with 12 rows and in each row there are 15 squares

from this grid she colours 8 squares from each row for 5 rows blue.

the rest of the squares she colours red

so first we have to find how many squares are there in the grid in total

so if each row has 15 squares

then 12 rows have - 15 x 12 = 180 squares

blue coloured squares

she colours 8 rows of 5 squares

so if 1 row has - 5 squares

then 8 rows have - 5 x 8 = 40 squares

from 180 squares, she colours 40 squares blue and the rest red colour

therefore the squares she colours red are

red squares = 180 - 40 = 140 squares

she colours 140 squares red

WORK:
12 rows of 15 squares = 12 × 15 = 180 squares
5 rows of 8 squares = 5 × 8 = 40 squares
180 squares - 40 squares = 140 squares
ANSWER:
Hannah colors 140 squares red.
