There are a few boxes with 12 red pens in each and a few boxes with 10 blue pens in each. If 10 red pens and 5 blue pens are removed, the total number of pens that remains is given by the expression (12x − 10) + (10y − 5). Here, x represents the number of boxes containing red pens and y represents the number of boxes containing blue pens.

Answer:

p = 12.20h

30.5 hours

Step-by-step explanation:

Jackson works as a veterinary technician and earns per hour = $12.2

He works in a normal week = 40 hours

Let hours = h and weekly pay = p

p = 12.20h

p = $12.20 × 40

= $488.00

Last week Jackson was ill and missed some work.

 His total pay before deduction was $372.10

To find the hours he work the equation will be p = 12.20h

372.10 = 12.20h

372.10/12.20 = h

h= 30.5

Answer: The expression would be 2b+7

Step-by-step explanation:

b will be the number of blue beads for the bracelet.

The number of red beads will be represented as b + 7.

Determine the expression for the total number of beads.

Then we can written it as,

= b + (b +7)

= 2b + 7.

Explanation:

Answer:

18 days.

Step-by-step explanation:

Step 1) Building an arithmetic sequence
We can build an arithmetic series with the given information.
The \(n\)th term of an arithmetic series is given by the formula \(a_n = a_1 + (n - 1)d\) .

\(a_1 = 500\\d = -15\\\to a_n = 500 - 15(n - 1) = 515 - 15n\)

Step 2) Finding the n for which a(n) = 245

As this step's title implies, we need to solve the equation \(a_n = 245\):

\(515 - 15n = 245 \text{ / Subtract 245}\\515 - 15n - 245 = 245 - 245\\\to 270 - 15n = 0 \text{ / Add 15n}\\270 - 15n + 15n= 0 + 15n\\\to 270 = 15n \text{ / Divide by 15}\\\frac{270}{15} = \frac{15n}{15}\\\to 18 = n\)

John will have $245 in 18 days.

Answer:

17 days

Step-by-step explanation:

Since John starts with $500 and each day, he’ll spend $15 on lunch. This means that:

Therefore, on his nth day, he’ll spend $15n where n represents the day. The problem can be modeled into an equation of \(\displaystyle{500-15n=245}\) since we will be finding how many days it will take to reach $245.

Then solve for n-term which we determines as the day variable:

\(\displaystyle{500-15n-245=0}\\\\\displaystyle{255-15n=0}\\\\\displaystyle{255=15n}\\\\\displaystyle{n=17}\)

Therefore, on his 17th day, he’ll have $245. Hence, the answer is 17 days.

Answer:

y=3.14x

Step-by-step explanation:

if you graph this on a calculator you can just visually see what line lines up with all the points. but you can also plug in one of the points into the equations to see if its true or not and if its true choose that equation. like use the first points (2, 6.28) and plug them into the equations and see which one is true.

The equation best represents the given data is y=3.14x. Therefore, option C is the correct answer.

Given that, a student measured the diameter and circumference of several circular objects.

The slope of the line is the ratio of the rise to the run, or rise divided by the run. It describes the steepness of line in the coordinate plane.

The formula to find the slope of a line is slope = (y2-y1)/(x2-x1)

From the table we have (2.0, 6.28) and (5.3, 16.64)

Now, slope = (16.64-6.28)/(5.3-2.0)

= 10.36/3.3

= 3.14

Substitute m=3.14 and (x, y)=(2.0, 6.28) in y=mx+c, we get

6.28=3.14(2.0)+c

c=0

Substitute m=3.14 and c=0 in y=mx+c, we get

y=3.14x

The equation best represents the given data is y=3.14x. Therefore, option C is the correct answer.

Answer: You can calculate the likeliness of the spinner landing on blue or red as the more spins you have the more accurate the results would be. In this case, after 200 spins Tiffany calculated that the spinner landing on blue has a 60% chance while landing on red has a 40% chance. Therefore this might not be fair as there is a 60% chance of landing on blue.

Step-by-step explanation:

The interquartile range of Bluejays is 40 and the interquartile range of Sparrows is 33. The correct option is B.

The interquartile range is a measurement of a data set's "middle fifty." A range is a measurement of where a set's beginning and end are located. To get the interquartile range, we must know the first and third quartiles. To find those, we need to know the median of the data.

Given that the Bluejays and the Sparrows are two baseball teams. Rajib recorded the number of hits per season the players scored in the past 5 years in two box-and-whisker plots. The number of hits per year scored by Bluejays players is the top plot, and the number of hits per year scored by Sparrow's players is the bottom plot.

The interquartile range of Bluejays is 40 and the interquartile range of Sparrows is 33.

Answer:

The rate of change in elevation for the second scuba diver is -82 feet per minute.

Step-by-step explanation:

-123 feet every minute.

1.5x more than 2nd diver.

-123/1.5 = 2nd diver rate

2nd diver rate = -82

The rate of change in elevation of the second scuba diver in feet per minute is -82 feet per second.

Given that, a scuba diver's elevation changed by -123 feet every minute.

When something has a constant rate of change, one quantity changes in relation to the other. For example, for every half  hour the pigeon flies, he can cover a distance of 25 miles. We can write this constant rate as a ratio. For ratios, it's always a good idea to state both units in whole terms.

1½=1.5 times the rate of change for a second scuba diver

Now, rate of change in elevation of the second scuba diver

= -123/1.5

= -82 feet per second

Hence, the rate of change in elevation of the second scuba diver in feet per minute is -82 feet per second.
