Match each rational number with a point on the number line.
(Be sure to use the numbers 1 through 4 to indicate which rational number goes in each answer box)

Answers

Answer:

The correct option is Option D) A=-0.7,B=-9/16,C=-0.4,D=-5/16

Step-by-step explanation:

Consider the provided number line.

From the number line we can observed that:

1) A, B, C and D lies between -1 and 0.

2) Point A and B lies between -1 and -0.5

3) Point C and D lies between -0.5 and 0

Therefore, the value of A and B must have a negative value lying between -1 and -0.5

Also, the value of C and D must have a negative value lying between -0.5 and 0.

Now consider the provided options.

Option A) A=-5/16,B=-9/16,C=-0.7,D=-0.4

This is Incorrect representation because the value of C and D should lying between -0.5 and 0.

Option B) A=-0.4,B=-0.7,C=-5/16,D=9/16

This is Incorrect representation because the value of A and B should lying between -1 and -0.5.

Option C) A=9/16,B=-5/16,C=-0.4,D=-0.7

This is Incorrect representation because the value of C and D should lying between -0.5 and 0.

Option D) A=-0.7,B=-9/16,C=-0.4,D=-5/16

Here the value of A and B lying between -1 and -0.5 also the value of C and D lying between -0.5 and 0.

Also they are in ascending order from -1 to 0.

Hence, the correct option is Option D) A=-0.7,B=-9/16,C=-0.4,D=-5/16

boxes. If they combine their candy and completely fill each box, how many full boxes will there be?

Answers

Answer:

16 boxes

Step-by-step explanation:

6 4/5+ 5 1/2+ 3 7/10

make all fractions with common denominators

6 8/10 + 5 5/10 + 3 7/10

combine like terms

6+5+3= 14

8+5+7 = 20/10 = 2

14+2 = 16

Answer:

550 pieces of candy (total), 150 pieces of candy for Maria, 200 pieces of candy for Lucas, 200 pieces of candy for Mateo.

Step-by-step explanation:

Maria filled

6 + 4 + 5 = 15 boxes of candy.

Lucas filled

3 + 7 + 10 = 20 boxes of candy.

Mateo filled

3 + 7 + 10 = 20 boxes of candy.

x = 10 pieces of candy.

15x = 150 pieces of candy (Maria).

20x = 200 pieces of candy (Lucas).

20x = 200 pieces of candy (Mateo).

150 + 200 + 200 = 550 pieces of candy in total.

On a piece of paper, use a protractor and a ruler to construct two equilateral triangles: one with a side length of 2 inches and one with a side length of 3 inches.

Which statement is true about the two triangles?

The two triangles are the same shape but not the same size.

The two triangles are the same size but not the same shape.

It is impossible to construct equilateral triangles with these side lengths.

The two triangles are the same size and same shape.

Answers

Answer:

Answer:

(B)

Step-by-step explanation:

We have to construct two equilateral triangles that is one with the side length of 2 inches and the another triangle with side length of 3 inches.

Now, both the triangles are equilateral triangles, thus they have same shape.

Also, both triangles have different side lengths, one having 2 inches and another having 3 inches, thus they have different size.

Hence, the true statement about the two triangles is:

The two triangles are the same shape but not the same size.

Therefore, option B is correct.

Step-by-step explanation:

Ben and Arnoldo are sharing snacks. They have peanut treats and coconut treats. Ben ate 2 of the peanut treats and 4 of the coconut treats for a total of 160 calories. Arnoldo ate 3 of the peanut treats and 2 of the coconut treats for a total of 140 calories. They wrote the system below to represent the number of calories there are in the two types of treats.

2 x + 4 y = 160. 3 x + 2 y = 140.

They found the solution to be (30, 25). How many calories are in each treat?

Answers

Answer:

It means there are 30 calories in peanut treat and 25 calories in coconut treat.

Step-by-step explanation:

There are 30 calories in peanut treat and 25 calories in coconut treat.

Given: Ben ate 2 of the peanut treats and 4 of the coconut treats for a total of 160 calories.

The equation corresponding to the above statement is

Also, Arnoldo ate 3 of the peanut treats and 2 of the coconut treats for a total of 140 calories.

The equation corresponding to the above statement is

i.e. x represents the number of calories in one peanut treat and y represents the number of calories in one coconut treat.

Also, the solution of system of linear equations is in the form of (x,y).

The given solution : (30,25)

It means there are 30 calories in peanut treat and 25 calories in coconut treat.
