The graph shows the number of paintballs a machine launches, y, in x seconds.
Which expression can be used to calculate the rate per second at which the machine launches the balls?
A) 80/4
B) 20/4
C) 4/80
D) 4/20
Answer:
B) 20/4
Step-by-step explanation:
Required rate = [tex]\frac{Number of balls launched}{Time}[/tex]
From the graph, it is evident that (4, 20), (8, 40), (12, 60) and (16, 80) are points.
This means that
20 balls launched in 4 seconds and the rate = 20/4
40 balls launched in 8 seconds and the rate = 40/8 = 20/4
60 balls launched in 12 seconds and the rate = 60/12 = 20/4
80 balls launched in 16 seconds and the rate = 80/16 = 20/4
Hence, the rate per second at which the machine launches the balls is 20/4 and the correct option is (B).

Aura picked the expression 9×3 to find the total number of flowers she picked. A) She picked 9 flowers and then picked 3 more flowers. B) She picked nine flowers from each of 3 flower beds. C)She picked 9 flowers and divided them into 3 cases. D) She picked 9 flowers and then put 3 into a vase.
The correct scenario is B) She picked nine flowers from each of 3 flower beds.
The question posed asks which scenario accurately describes the mathematical expression 9×3 in the context of picking flowers. The expression 9×3 implies that the number 9 (the number of flowers picked from one bed) is multiplied by 3 (the total number of beds from which flowers are picked), thus resulting in a total count of flowers picked. Therefore, the multiplication of these two numbers indicates repeated addition, such as picking a set number of flowers from multiple identical sets.
Additionally, if we were to consider other aspects such as flower color ratios or Darwinian genetics, we could take example scenarios such as: "50% of the flowers are blue and 50% of the flowers are red" or "You would expect 300 homozygous dominant blue flowers, 300 heterozygous blue flowers, and 200 homozygous recessive red flowers", but these do not pertain directly to the mathematical operation represented by 9×3 in this context.
Find the percent markup from wholesale cost to selling price.
Answer:
$650 - $200 = $450
$200 = p × $450
p = 20/45 = 4/9 = about 44%
The percent markup is about 44%.
To find the percent markup from wholesale cost to selling price, calculate the difference between the selling price and the wholesale cost, divide that difference by the wholesale cost, and multiply by 100.
Explanation:To find the percent markup from wholesale cost to selling price, you need to calculate the difference between the selling price and the wholesale cost, and then divide that difference by the wholesale cost. Finally, multiply the result by 100 to get the percent markup.
For example, if the wholesale cost is $50 and the selling price is $75, the difference is $25. Dividing $25 by $50 gives you 0.5, and multiplying by 100 gives you a 50% markup.

What formula should I use for this?
Kyle divided 2 3 on his calculator and got .6667. Where did the 7 come from?
The 7 in .6667 when Kyle divided 2 3 came from rounding the decimal during the calculation process in the calculator.
The 7 in .6667, when Kyle divided 2 3 on his calculator, came from rounding the decimal.
When a calculator displays a decimal, it often rounds the number to a specific decimal place, causing the appearance of non-repeating numbers like 7 in this case.
Limited by the display's capacity for decimal places, calculators round off the result, leading to the appearance of additional digits beyond the actual result.
triangles q'r's' is a translation of triangle QRS which transformation created triangle q'r's'
A. Translation 3 units left and 5 units up
B. Translation 5 units left and 3 units up
C. Translation 3 units right and 5 units down
D. translation 5 units right and 3 units down
To determine which transformation created triangle q'r's' from triangle QRS, one would compare the vertices of the original and translated triangles. This comparison would reveal the horizontal and vertical distances each point has been moved, indicating the correct translation.
Explanation:The question asks which transformation created triangle q'r's' from triangle QRS. The correct answer will be the translation that moves triangle QRS to the new position of triangle q'r's'. When a figure is translated, all points move the same distance in the same direction. Given the options, we need to choose the translation that shifts the triangle in the correct direction and by the correct number of units.
Without specific coordinates, we cannot determine the exact translation from the given options. However, if we had the positions of triangles QRS and q'r's', we could compare their corresponding vertices to find the difference in their 'x' (horizontal) and 'y' (vertical) coordinates. This difference would tell us how far and in which direction the triangle has been translated.

The means and mean absolute deviations of the individual times of members of two relay swim teams are shown in the table below.
Means and Mean Absolute Deviations of
Individual Times of Members of 4*200- meter Relay Swim Teams
Team A Team B
Mean 127.9 s 127.4 s
Mean Absolute Deviation 0.26 s 0.23 s
The difference of the means is found and then compared to each of the mean absolute deviations. Which is true?
The difference between the mean times is about equal to the mean absolute deviation of the data sets.
The difference between the mean times is about 2 times the mean absolute deviation of the data sets.
The difference between the mean times is about 5 times the mean absolute deviation of the data sets.
The difference between the mean times is about 16 times the mean absolute deviation of the data sets.
The difference between the mean times is about 16 times the mean absolute deviation of the data sets.
Step-by-step explanation:We are given the mean and mean absolute deviation of two teams in a table as:
Team A Team B
Mean 127.9 s 127.4 s
Mean Absolute Deviation 0.26 s 0.23 s
The difference of mean between two team is: 0.5 s
( Since 127.9-127.4=0.5 s)
Also, the difference of Mean absolute deviation is: 0.03 s
( Since, 0.26-0.23=0.03 s)
Now let the difference of the mean times be equal t n times the difference of the mean absolute deviation of two teams
i.e.
0.5=n×0.03
⇒ n=0.5/0.03
⇒ n=16.6667
which is approximately equal to 16.
Hence, The difference between the mean times is about 16 times the mean absolute deviation of the data sets.
Theo bought two hot dogs and two sodas for $4.00. At the same concession stand, Vicky bought three hot dogs and a soda for $4.50. What is the price of a hot dog at the concession stand?
If Theo bought two hot dogs and two sodas for $4.00. At the same concession stand, Vicky bought three hot dogs and a soda for $4.50. Then $1.125 is the price of a hot dog at the concession stand
What is Equation?Two or more expressions with an Equal sign is called as Equation.
Given,
Theo bought two hot dogs and two sodas for $4.00.
Let hot dogs denoted by H
Soda denoted by S
2H+2S=4...(1)
Vicky bought three hot dogs and a soda for $4.50
3H+S=4.50..(2)
Multiply (2) with 2
6H+2S=9..(3)
Now subtract 3 from 1
2H+2S-6H-2S=4.50-9
-4H=-4.5
H=1.125
Now plug in H value in 2
3(1.125)+S=4.5
3.375+S=4.5
S=4.5-3.375
S=1.125
Hence $1.125 is the price of a hot dog at the concession stand

Zander uses an on-line store that sells
songs for $1 each and movies for $6.
He used all of his $20 allowance to buy
10 items.
a. Write one equation in a system for this situation.
b. Write a second equation in the system.
c. What do x and y represent?
d. How many songs and how
many movies did he buy?
To solve this problem, set up a system of equations and solve for the number of songs and movies Zander bought using substitution or elimination.
Explanation:To solve this problem, we can set up a system of equations to represent the situation:
x + y = 10
$1x + $6y = $20
The first equation represents the total number of items Zander bought, which is 10.The second equation represents the total amount of money Zander spent, which is $20.x represents the number of songs Zander bought, and y represents the number of movies Zander bought.To solve the system of equations, we can use any method, such as substitution or elimination. For example, using substitution, we can solve for x in the first equation and substitute it into the second equation to find the value of y.Once we have the value of y, we can substitute it into the first equation to find the value of x.So, Zander bought 4 songs and 6 movies.One hundred nautical miles equals about 185 kilometers.
