Sid has a baseball cap collection. 65% of his caps have sports team symbols. If 26 of the caps have the team symbols, how many total caps does Sid have?
39
40
73
91
B. 40
As we know Sid has 26 Caps
we also know that 26 is 65% of total
so let total caps = x
to calculate x
we know that percent = (Values*100)/total Values.......... i
and here Value = 26 caps
percentage = 65
So we have
65 = (26*100)/x---------------- (As we know that per = fraction*100)..... from i
65x= 2600x = 2600/65x=40 capsHence Answer is 40

Answer:
Step-by-step explanation:
Julie's income for 16 hours is $192. Julie takes only 24 hours to earn $288. The rate is $12 for each hour.
Given
Loren and Julie have different part-time jobs after school.
They are both paid at a constant rate of dollars per hour.
The income of Julie is $36 in 3 hours.
For 1 hour, Julie earns $12.
Thus the rate of Julie is $12 per hour.
For the 16 hours, Julie's income will be.
Julie's income for 16 hours = 12 x 16
Julie's income for 16 hours = $192
Julie's income for 16 hours is $192.
Julie takes time to earn $228 will be

I'm super confused about this
The manager of fast food restaurant collected data to study the relationship between the number of employees working registers and the amount of time customers waited in line to order. He made a scatter plot of the data and credited a trend line with the equation y= -70x+300, where y is the total amount of time waited in seconds and x is the number of employees working registers.
1. Did the scatter plot of data positive, negative, or no association? Explain your reasoning.
2. Maria went to the restaurant and waited 90 seconds to place her order. Use the trend line equation to predict how many employees were working.
3. Kiara went to the restaurant and waited 3.5 minutes. Use the trend line to predict how many employees are working.
4. Ashton walked into the restaurant and 4 employees are working registers. Use the trend line equation to predict how long he will wait to place his order.
Answer:
Step-by-step explanation: "no association because depending on how many people are working and how many people are coming in at the same tome"

Find the lower quartile and upper quartile of the data set. 10, 11, 13,18,19,21,22,25,27,30,32
The lower quartile value is 13 and the upper quartile value is 27.
What is a Quartile?
A quartile divides the data set into four equal halves, that is, each set has an equal number of terms. The quartiles are given by Q₁(the lower quartile value), Q₂ (the median), Q₃ (the upper quartile value).
We first arrange the data set in ascending order. Here, the data set is already in ascending order, that is, 10,11,13,18,19,21,22,25,27,30,32.
So we will divide the above set into two equal halves. As the given set has 11 terms,
So the median is [tex]\frac{n+1}{2}[/tex] where n is the number of terms.
We have n=11
⇒ Median= [tex]\frac{11+1}{2}[/tex] th term
= 6th term
⇒ Median= 21
Now the data to the left side of the median value will give the lower quartile and the data to the right will give the upper quartile.
The data to the left of median value 21 is 10,11,13,18,19.
The median value of this data will give the lower quartile value.
Median = [tex]\frac{5+1}{2}[/tex]th term= 3rd term
=13
⇒Lower quartile is 13.
The data to the right of the median value 21 is 22,25,27,30,32
The median value of this data will give the upper quartile value.
Median = [tex]\frac{5+1}{2}[/tex]th term= 3rd term
= 27
⇒Upper quartile is 27.
The correct answer is lower quartile= 13, upper quartile = 27

A box 2 m by 4 m by 8 m is filled with cubes of volume 8 cm³. If these
cubes were lined up, how long a line would that be?
The total line length of cubes lined up would be approximately 1.6 x 10^7 cm.
To find the total line length of cubes lined up, we need to find the total number of cubes in the box and then multiply it by the side length of a cube.
We can find the total number of cubes in the box by dividing the volume of the box by the volume of a cube:
Volume of the box = 2 m * 4 m * 8 m = 64 m³
Volume of a cube = 8 cm³ = 8 x 10^-6 m³ (converting the cm³ to m³)
Number of cubes = 64 m³ / 8 x 10^-6 m³ = 8 x 10^6
Then we can multiply the total number of cubes with the side length of a cube to find the total line length of cubes lined up :
Therefore, Line Length = 8 x 10^6 * 8 cm
= 6.4 x 10^7 cm
= 1.6 x 10^7 cm.

Solve the system of linear equations by elimination. Check your solutions.
-5x + 3y = -6
9x - 4y = 1
We can divide both sides of the equation by 43 to solve for x:
90x / 43 - 47y / 43 = -49 / 43
x = -49/43
We can substitute this value for x back into either of the original equations to find y. Let's substitute it into the first equation:
-5x + 3y = -6
(-5 * -49/43) + 3y = -6
y = (-6 + 5 * 49/43) / 3
y = 17/43
The solution to the system of equations is (x, y) = (-49/43, 17/43).
To check our solution, we can substitute the values we found for x and y back into the original equations and see if they hold true.
In the first equation, -5x + 3y = -6, substituting the values we found for x and y gives us:
(-5 * -49/43) + (3 * 17/43) = -6
This simplifies to -6 = -6, which is true, so the solution holds for this equation.
In the second equation, 9x - 4y = 1, substituting the values we found for x and y gives us:
(9 * -49/43) - (4 * 17/43) = 1
This simplifies to -1 = -1, which is true, so the solution holds for this equation as well.
Therefore, the solution (x, y) = (-49/43, 17/43) is correct.
