The table below shows the number of skateboards sold at a skate shop each week for five weeks.
w # of weeks 1 2 3 4 5
skateboards sold 22 44 66 88 110
Which equation represents the relationship between w, the number of weeks and s the number of skateboards sold?
s = 22w
s = 22/w
s = w/22
s - w = 22
Answer:
s = 22w
Step-by-step explanation:
We need to try this equation for all of the numbers in the table.
s = 22w
22 = 22 * 1
s = 22w
44 = 22 * 2
s = 22w
66 = 22 * 3
s = 22w
88 = 22 * 4
s = 22w
110 = 22 * 5
Answer:
A. s = 22w
Step-by-step explanation:
22/1 = 22
44/2 = 22
66/3 = 22
88/4 = 22
110/5 = 22
There are currently 6,210 fish in a lake. If the number of fish in the lake increased by 15 percent during the last year and 20 percent during the year before that, how many more fish are in the lake currently than in the last two years ago?
I’m pretty sure the answer should be 1,710 if not i’m sorry
Answer:
1710 fish
Step-by-step explanation:
Let the number of fish in the lake last year be 'x'
The equation becomes-
x + 15x/100=6210 (This is because 15% of x is added in x to become
6210... hope you understand)
x + 15x/100 = 6210
115x/100 = 6210
23x/20 = 6210
x = 6210 * 20/23
x = 270 * 20
x = 5400
Therefore- The number of fish last year = 5400
Now, let the number of fish in the lake 2 years ago be 'y'
The equation becomes-
y + 20y/100 = 5400 (Same logic as last time)
y + 20y/100 = 5400
120y/100 = 5400
24y/20 = 5400
6y/5 = 5400
y = 5400 * 5/6
y = 900 * 5
y = 4500
Therefore- Fish in the lake two years ago = 4500 fish
Difference between current and two years ago = 6210-4500
= 1710 fish

An artist wants to create a poster that includes a picture of the winners of
the 1500-meter race at the Olympics from 1896 to 2000. If a man has won
the race more than once, his picture will only appear once. The pictures will
be laid out in columns and rows, and they will be placed randomly. The top
row will contain four pictures. What is the probability that the top row will
include Josy Barthel of Luxembourg, Teddy Flack of Australia, Noah Negeny
of Kenya, and Jim Lightbody of the United States?
Using the combination formula, it is found that there is a \(p = \frac{1}{1540}\) probability of the desired top row.
What is the combination formula?\(C_{n,x}\) is the number of different combinations of x objects from a set of n elements, given by:
\(C_{n,x} = \frac{n!}{x!(n-x)!}\)
Looking at the table, there are 22 different winners, and 3 will be selected for the total row, hence the total number of options is given by:
\(T = C_{22,3} = \frac{22!}{3!19!} = 1540\).
There is only one desired combination, as the order does not matter, hence the probability is given by:
\(p = \frac{1}{1540}\)

400 ducks consume a reservoir of feed in 30 days, how long will it take 500 ducks
Answer:
24 days.
Step-by-step explanation:
First lets look at the facts.
400 ducks can eat a bunch of feed in 30 days.
That means that 200 ducks would take 60 days.
100 ducks would take 120 days.
Now, we must multiply 100 by 5 to get 500, the target amount of ducks, and divide 120 by 5 to get 24. So, 500 ducks can eat a reservoir of feed in 24 days.
Answer:
24 days
Step-by-step explanation:
It is an inverse proportion, the more ducks the less days the food lasts
400 ----- 30
500 ----- X
\(x=\frac{(400)(30)}{500} =\frac{12000}{500} =24\)

Regina kept track of the points she scored during her team’s first eight basketball games. What is Regina’s mean score?
Responses
A 3939
B 1616
C 3737
D 1313
E 17
Answer:
Mean = 16
Step-by-step explanation:
MEAN can be find bg the sum of all score divided by the amount of the score.
Mean = total amount / number of amount
Total amount = 2 + 3 + 5 + 9 + 17+ 22 + 31 + 39
= 128
number of amount = 2, 3, 5, 9, 17, 22, 31, 39
= 8
Then we can calculate mean as
Mean = 128/8
Mean = 16
A bag contained 18 red marbles, 14 green marbles, and 20 blue marbles. A marble was randomly pulled, the color recorded, and then put back into the bag. This table above shows the results after 25 pulls.
What was the relative frequency of selecting a red or blue marble?
Red:8
Blue8
Green9
Number of red marbles pulled = 8
Number of blue marbles pulled = 8
Total marbles pulled = 25
Relative Frequency = Total Frequency / Total number of data values
Relative Frequency of red marble = 8/25
= 32%
Relative Frequency of blue marble = 8/25
= 32%

Which of the following tables shows a relationship between x and y?
Answer:
D
Step-by-step explanation:
For each ride, a taxi service charges an initial fee plus an additional fee based on the number of kilometers of the trip. The graph shows the cost for taxi rides. Select a true statement. The rise is 4 while the run is 2. The selection of answers are:
A: The slope is 2.1. This means that each kilometer costs $2.10.
B: The slope is 5. This means that each kilometer costs $5.
C: The y-intercept is 2.1. This means that the initial fee is $2.10.
D: The y-intercept is 5. This means that the ride lasts 5. kilometers.
Which one is right and why?
THIS MIGHT NOT BE WHAT YOU ARE LOOKING FOR AND MIGHT NOT BE CORRECT! READ FIRST!
The answer is A. The slope of the line is rise/run = 4/2 = 2.1. This means that each kilometer costs $2.10. The y-intercept is 2.1, which means that the initial fee is $2.10. So the correct statement is: The slope is 2.1. This means that each kilometer costs $2.10.
The other statements are incorrect. The slope is not 5, so each kilometer does not cost $5. The y-intercept is not 5, so the ride does not last 5 kilometers. The y-intercept is the value of the function when the input is 0, which in this case is the initial fee of $2.10.

When you are writing a similarity statement, you must put the letters of both triangles in the same order. In other words, you must make the first letter of the first triangle match with the first letter of the second triangle, and so on.
In this figure, \(\angle K\cong\angle E\), \(\angle L\cong\angle T\), and \(\angle KUL\cong\angle EUT\). Hence,
\(\triangle KLU \sim \triangle ETU\)
Since K is first, E is also first, as ∠K matches to ∠E. Since L is second, T is also second, as ∠L matches to angle ∠T.

Factor the expression using the GCF.
Answer:
Step-by-step explanation:
In this problem, both 7 and 14 can be divided by 1 and 7, meaning these are the factors. This tells us that 7 is the Greatest Common Factor, as 7 is greater than 1.
To factor the expression, we take 7 out of both numbers and put it outside the expression. To do this, we have to divide both numbers by 7. Doing this gives us \(7(\frac{7}{7} +\frac{14}{7} )\), which simplifies to \(7(1 + 2)\).
