Answer:
1. Time (hours): 1 Distance (miles): 45
2. 1;45
2;90
3;135
4;180
5;225
6;270
3. (c= constant of proportionality)
c= [tex]\frac{distance}{time}[/tex]
c=[tex]\frac{90 miles}{2 hours}[/tex]
c= 45 miles per hour
Step-by-step explanation:
So you may see for each hour they are going 45 miles by dividing 2 by 2 and 90 by 2, so there constant of proportionality is 45 miles per hour. (answer 3 is the step by step)
Barb pulled the plug in her bathtub and it started to drain. The amount of water in the bathtub as it drains is represented by the equation L = -5t - 8t + 120, where L represents the number of liters of water in the bathtub and t represents the amount of time, in minutes, since the plug was pulled. How many liters of water were in the bathtub when Barb pulled the plug? Show your reasoning. Determine, to the nearest tenth of a minute, the amount of time it takes for all the water in the bathtub to drain.
The bathtub had 120 L of water before Barb pulled the plug.
It will take about 9.23 minutes for the water to drain out.
Given equation: L = -5t - 8t + 120
Simplified: L = -13t + 120
Notice how it's written in slope-intercept form (y = mx+b)
The y-intercept (L) is 120. So the coordinates for L = (0 , 120)
The coordinates mean that before the water in the bathtub began draining out, it initially had 120 Liters of water.
Now that we know how many liters there were before, the new equation would look like this: L = -13t --> 120 = -13t
Solving the equation, we get that t = -9.23 minutes
Since time can't be negative, we'll just say that it will take 9.23 minutes to drain out all the water.

1st box: 6/9

3rd box: 5/9
Step-by-step explanation:
Finding the LCD is pretty simple here, it has to at least be the highest denominator, which is 9, and since 3 goes into 9 evenly we get a LCD of 9.
Then to make the fractions correct we do 2/3 x 3/3 which is 6/9.
So now we figure out 6/9 - 1/9 which is just subtracting the numerator so 6/9 - 1/9 = 5/9 and since that is the most it can be simplified, 5/9 is our answer. Hope this helps!
Answer:
6/9
1/9
5/9
What is a least common denominator?
Well, a least common denominator is the smallest number of all the common multiples of the denominators when 2 or more fractions are given.
Find LCM(3, 9)
3: 3, 6, 9,
9: 9
2/3 = 2/3 × 3/3 = 6/9
1/9 = 1/9 × 1/1 = 1/9
2/3 = 6/9
1/9 = 1/9
6/9 - 1/9 = 5/9
Therefore the answers are in bold.

Do 18/24 and 10/15 have the same value? Explain your answer in complete sentences.
Answer:
No
Step-by-step explanation:
We can either cross multiply or turn into decimal form to see if they have the same value.
I will be showing both.
Cross Multiply: Decimal Form:

We can conclude that 18/24 and 10/15 are not the same.

How many triangles are determined?
Triangle weighs 3 grams Circle weighs 6 grams. Write an equation to represent each hanger. Let x represent the pentagon.
Answer:
Answer: 3.75 g
Step-by-step explanation:
Assume the weight of the square is x.
The hanger is in balance so the left side is equal to the right side.
Equation therefore is:
Triangle + Square + 3 * circle = 5* square + circle
3 + x + (3 * 6) = 5x + 6
3 + x + 18 = 5x + 6
5x - x = 3 + 18 - 6
4x = 15
x = 15/4
x = 3.75 g

-1 1/2 _ -1 3/4 which one is greater or less, or equal?
Answer:
The answer is -1 1/2 is less than -1 3/4
Step-by-step explanation:
I look at it more as numbers, so for example 1/2 can be simplified into 50, and 3/4 is 75/ 75 would be greater if it was positive. But, with there being a negative 1 in front of the answer, the lowest number closest to 0 is better. :D
Answer: -1 1/2 is greater
Step-by-step explanation:
-1 1/2 is closer to zero and that makes it larger because they are negative numbers.
What is the sales tax on a refrigerator priced $1269, if the sales tax rate is 6.7%?
Answer:
sales tax: $85.023
Explanation:
Original or actual price is always of 100%
Solving:
100% = $1269
Find the unit percent :
1% = $(1269/100) = $12.69
Find the sales tax :
$12.69 × 6.7 = $85.023

You have recently purchased a new backpack as show in the picture. The main section of the backpack is made of a rectangle gular prism. Use the diagram to find the volume of your new backpack, then explain how u calculated the answer. Use the pictures with the formulas to help also use the sentence starters.
Sentence Starters:
The volume of the large rectangular prism (the bottom part of the backpack) is __inᶾ.
The volume of the pocket, which is also a rectangular prism is _____ inᶾ.
The volume of the half cylinder, which is the top curve of the backpack, is _____ inᶾ.
When you add all three of these together, you get the total volume of _____ inᶾ.
Hint: Find the volume of each shape; there are 3 of them; two rectangular prisms and half of a cylinder, and then add all 3 of them together. For the cylinder, you only need half, so find the volume of the whole cylinder then divide it by 2 for half. )
Answer:
Main part of backpack V = 840 inᶾ
Front pocket of backpack V = 64 inᶾ
Top curve of the backpack V = 395.8406744 inᶾ
Total V = 1299.840674 inᶾ
Step-by-step explanation:
1.
As we know, the formula for the volume of a rectangular prism is width x height x length (V = whl). We will use this formula to find the volume of the large rectangular prism (bottom part of the backpack) and the volume of the smaller rectangular prism (the pocket). As for the cylinder, we know the formula for the volume of a cylindrical prism is pi x radius squared x height (V = πr^2h). We will use this formula to find the volume of the half cylinder (top curve of the backpack).
2.
For the large rectangular prism (main part of the backpack), we are given:
w = 7in
h = 10in
l = 12in
Now let's incorporate our formula for the volume of a rectangular prism into this situation.
V = whl
V = 7 x 10 x 12
V = 840 inᶾ
3.
Now for the smaller rectangular prism (front pocket of backpack), we are given:
w = 2in
h = 4in
l = 8in
Now let's incorporate our formula for the volume of a rectangular prism into this situation.
V = whl
V = 2 x 4 x 8
V = 64 inᶾ
4.
Now to calculate volume for the half cylinder (top curve of the backpack), we must first imagine that this is a full, circular cylinder. We are given:
r = 6in
h (which will be the same as the width of the backpack in this case scenario) = 7in
Now let's incorporate our formula for the volume of a rectangular prism into this situation.
V* = πr^2h
V* = π x 6^2 x 7
V* = 791.6813487 inᶾ (round this number if you must)
Now that we have the volume of a whole cylinder, we can halve it (divide by two) since we only need half of the cylinder.
V = V*/2
V = 791.6813487/2
V = 395.8406744 inᶾ (round this number if you must)
5.
Finally, we can add our volumes together to acquire the volume of the backpack as a whole!
Large rectangular prism (bottom part of the backpack) + Smaller rectangular prism (the pocket) + Half cylinder (top curve of the backpack) = Total Volume (Whole backpack)
Recall that:
Large rectangular prism (bottom part of the backpack) = 840 inᶾ
Smaller rectangular prism (the pocket) = 64 inᶾ
Half cylinder (top curve of the backpack) = 395.8406744 inᶾ
So:
Total Volume (Whole backpack) = 840 inᶾ + 64 inᶾ + 395.8406744 inᶾ
Total Volume (Whole backpack) = 1299.840674 inᶾ (round this number if you must)

What is the interquartile range of the data? With the numbers 2,3,3,4,5,7,8,8,8,10,10, and 12
Answer:
5.5
Step-by-step explanation:
2,3,3,4,5,7,8,8,8,10,10,12
The mean of this data is 7.5. So what you are trying to figure out is the mean between 2 and 7. Since that is 3 and 4 it would be 3.5. So 3.5 is the Q1. Now you have to figure out the mean between 8 and 12. That is 9. This is Q3. You have to subtract 9-3.5 and that is the interquartile range. So 5.5 is the answer. I hope that made sense.
