Her brother eat? Her mother eat? b) Which person’s fraction can you write in more than one way? Explain. c) What fraction of the pizza was eaten? What fraction was left?
Answers
Answer: Meena ate 1/8. Her brother ate 2/8, and her mom ate 3/8ths of the pizza. Her brother can be simplified from 2/8 to 1/4. Lastly, 6/8ths of the pizza has been eaten. 2/8ths is all that remains.

1. The length of a necklace that you make at a rate of 10 cm per hour without taking a break.
Step-by-step explanation:
Okay so lets think about this by first looking at the graph we are given.
Whatever is going on, its going up, and steadily. There's no points were the line goes down or curves, right? So it's constant and forward. So now let's look at the possible answers.
1. The length of a necklace that you make at a rate of 10 cm per hour without taking a break.
Is is constant? Yes, the rate is 10 cm/hr. Does it stop? No, you don't take a break. Is it forward? Yes, you are making more of the necklace, not less.
Thinking of the y-axis as amount of necklace made, and x-axis as time spent, this is the right graph.
So this is your answer!! Just to be sure, let's look at the other possible answers.
2. The height of a balloon as it rises, gets caught in a tree, then continues to rise.
This is not constant, because it gets stuck and stops. But it is forward, because it is rising.
Thinking of the y-axis as the height of the balloon, and x-axis as time passed, this is NOT the right graph.
This is not the answer.
3. The total distance you are from home if you ride your bike three mi/hr for 1 hour, then stop for a rest.
It is not constant, because you stop and take a break. But it is forward, because you are moving forward.
Thinking of the y-axis as the speed or distance from home, and x-axis as time passed, this is NOT the right graph.
This is not the answer.
4. The volume of water in a bath tub as it is draining.
This one IS constant, but in the wrong direction. The tub is draining, not filling, so the amount is decreasing. This would be the correct graph, if the slope were negative and the line was like this \ and not like this /.
Thinking of the y-axis as the amount of water in the tub, and x-axis as time passed, this is NOT the right graph.
This is not the right answer.
These leave us with the first answer as being correct.

If two ratios are similar we called the ratios to be in proportion.
The length of side x is 6 cm.
What is proportion?If two ratios are similar we called the ratios to be in proportion
We have,
Two shapes:
Consider the bigger shape width = 15 cm and length = 10 cm.
Consider the smaller shape width = 9 cm and length = x cm.
Let the ratio of bigger shape:
= Width / length
= 15/10
Let the ratio of smaller shape:
= Width / length
= 9/x
If the two figures are mathematically similar we can say that the two figures are in proportion.
We can write it as:
15/10 = 9/x
3/2 = 9/x
x = 6
Thus the length of side x is 6 cm.

Answers
Answer:
1/7
Step-by-step explanation:
Given that :
Line AB contains points A (8, −4) and B (1, −5)
Slope = Rise / Run
Rise = y2 - y1 = - 5 - (-4) = - 5 + 4 = - 1
Run = x2 - x1 = 1 - 8 = - 7
Slope = Rise / Run = - 1 / - 7
Slope = 1/7

If V is the midpoint of Line segment Q S and W is the midpoint of Line segment R S, then what is VS? 4 units 8 units 10 units 20 units
Answers
Answer:
20 units
Step-by-step explanation:
We can see that triangle QRS and triangle VWS are similar triangles.
Similar triangles are triangles in which the ratio of their corresponding sides are in the same proportion.
V is the midpoint of QS.
VS = 2a, QS = 2 * VS = 2(2a) = 4a
Since both triangles are similar triangles, hence:
[tex]\frac{VS}{QS}=\frac{VW}{QR}\\\\\frac{2a}{4a} =\frac{2a-2}{3a+6} \\\\\frac{2a-2}{3a+6} =\frac{1}{2} \\\\2(2a-2)=3a+6\\\\4a-4=3a+6\\\\a=10\ units\\\\VS=2a=2(10)=20\ units[/tex]

On Sunday, the high temperature was 71° F, but on Monday it was 5° F lower. What was the percent change?
Answers
Answer:
The percent change is -7%.
Step-by-step explanation:
In order to find the answer, you can use the following formula:
Percent change=(New value-Old value/Old value)*100
New value=71-5=66
Old value=71
Now, you can replace the values on the formula:
Percent change=(66-71/71)*100
Percent change=(-5/71)*100
Percent change=-0.07*100
Percent change=-7%
According to this, the answer is that the percent change is -7%.
