Write the solution to the inequality in set - builder notation:
5r + 8 < 63

Answers

Answer 1
First, the inequality needs to be solved. The first step is to subtract 8 from both sides of the inequality, leading to 5r < 55. Dividing 5 out from both sides, this will leave r < 11. Next, to form a set notation, the inequality is written in such form: {r | r < 11}.

Answers

Well, I don't know the number of bowling balls they sold is it 10, 5 or 105 but the answer is just the number of sold balls multiplied by 45. Make sure to put a dollar sign on your answer.

The required money earned by the company after selling 10⁵ balls is $4500000. Option C is correct.


A bowling ball manufacturer's heaviest bowling ball weighs 21 pounds and costs $45. The corporation sold 10 5 105 of these balls throughout the course of the previous year. To determine how much money did the company earn.


What is simplification?

The process in mathematics to operate and interpret the function to make the function or expression simple or more understandable is called simplifying and the process is called simplification.

Here,
Number of balls sold = 10⁵
Cost for 1 ball = $45
Total selling price = 45 * 10⁵ = $4500000

Thus, the required money earned by the company after selling 10⁵ balls is $4500000. Option C is correct.

find the value of x and y

Answers

What do we know about these angles? Immediately, you might notice that (4y-8)° and (16x-4)° share a line. The same is true of (16x-4)° and (14x+4)°. Any straight line forms what's called a straight angle, which measures 180°, so we know that, since they add up to form a straight angle, (14x+4)° and (16x-4)° must add up to 180°. We can use that fact to set up an equation to solve for x:

(14x+4)+(16x-4)=180

After you solve for x, you should look to solve for y. How can we figure out what y is? If you're familiar with the vertical angle theorem, you'll know that all vertical angles (angles that are directly across from each other diagonally) are equal. So we know that 14x+4=4y-8. You can use the value of x you solved for before to solve this one fairly easily, and then you'll have both values.

In a dance competition, a participant has to score a total of at least 30 points in the first four rounds combined to move on to the fifth and final round. Steward scored 5 points in the first round. He then went on to score additional points in the second, third, and fourth rounds. In each of those rounds, his score was identical. Which inequality best shows the number of points, p, that Steward scored in each of the second, third, and fourth rounds if he earned a place in the finals?
A. 5 + 3p ≥ 30
B. 5 + 3p ≤ 30
C. 5p + 3 ≥ 30
D, 5p + 3 ≤ 30

Answers

The answer is A because you know he scored 5 points in the first round. Then you don't know what he scored in the next rounds. You also know that the total points have to be greater than or equal to 30. Therefore the correctly set up inequality is A. Hope this helps!

Answer:

I'm pretty sure the answer is A.

Step-by-step explanation:

Because those first 5 points + the other 3 rounds that had the same amount of points scored. So, 5 + 3p (in other words, P is representing the unknown number of points scored in those 3 other rounds. So, Choice A is your answer. ;)

A touchdown is worth 6 points. Additionally you score an extra point if you can kick a field goal . Is the total number of points scored proportional to the number of touchdowns

Answers

No because a touchdown is worth 6 and the extra points is worth 4 or 2
Sort of because you can also go for two extra points by throwing or running it into the end zone and you may also miss the extra point into the field goal. Also there are safety's where the quarterback is tackled in there end zone which is worth 2 points toward the opposing team and field goals where the ball is kicked on fourth down and they never made it into the end zone which is worth three points for the team if they make it into the field goal.

write the equation of a line that is perpendicular to the line 5x-3y=12 and passes through point (3,1)

I know that the answer is y=-3/5x+14/5

Answers

–4x – 3y = 6
and/or
m = 3/4
Hope this helps! :)

Final answer:

To find the equation of a line that is perpendicular to 5x-3y=12 and passes through (3,1), we first identify the slope of the given line, find the negative reciprocal to determine the perpendicular slope, and then use the point-slope form to derive the equation, resulting in y = -3/5x + 14/5.

Explanation:

The question asks us to write the equation of a line that is perpendicular to the given line 5x-3y=12 and passes through the point (3,1). Perpendicular lines have slopes that are negative reciprocals of each other. First, we find the slope of the given line by rearranging it into slope-intercept form:

5x - 3y = 12
-3y = -5x + 12
[tex]y = \(\frac{5}{3}x - 4\)[/tex]

This reveals the slope of the given line is  [tex]\(\frac{5}{3}\).[/tex] The slope of the line perpendicular to it would therefore be [tex]\(-\frac{3}{5}\)[/tex]since  [tex]\(-\frac{3}{5}\)[/tex]is the negative reciprocal of  [tex]\(\frac{5}{3}\).[/tex] Next, we use the point-slope form for the equation of a line with the known point (3,1):

y - y1 = m(x - x1)
[tex]y - 1 = \(-\frac{3}{5}\)(x - 3)[/tex]

Multiplying out, we get:

[tex]y - 1 = \(-\frac{3}{5}\)x + \(\frac{9}{5}\)[/tex]

Finally, adding 1 to both sides to solve for y:

[tex]y = \(-\frac{3}{5}\)x + \(\frac{9}{5}\) + 1[/tex]
[tex]y = \(-\frac{3}{5}\)x + \(\frac{14}{5}\)[/tex]

This is the equation of the line that is perpendicular to 5x-3y=12 and passes through (3,1).

what is the price of a remote control helicopter is $34.40. A remote control boat cost 4/5 the price of the helicopter. Sales tax on the remote control boat is 8%. What is the price of the remote control boat, including sales tax? Round your answer to the nearest penny

Answers

The answer rounded would be 29.94
First, let’s multiply 34.4 to get 1% of that price.
34.4 x 0.01 = 0.344
Then, let’s multiply that 1% by 80 to get the price of the remote controlled boat, since it’s 4/5 the price of the helicopter.
0.344 x 80 = 27.52
$27.52 is the regular price of the boat.
Now, let’s find the 8% of that price. We’ll first first 1% and then multiply our answer by 8 to get 8%.
27.52 x 0.01 = 0.2752
0.2752 x 8 = 2.2016
Sales tax will be $2.20
The total will add the sales tax to the regular total of the boat.
$27.52 + $2.20 = $29.72
$29.72 is your answer.

Police set up an auto checkpoint at which drivers are stopped and their cars inspected for safety problems. They find that 14 of the 134 cars stopped have at least one safety violation. They want to estimate the percentage of all cars that may be unsafe.

Answers

Final answer:

To estimate the percentage of all cars that may be unsafe, divide the number of cars with safety violations by the total number of cars stopped, and then multiply by 100. Based on the data from the auto checkpoint, approximately 10.45% of all cars may be unsafe.

Explanation:

To estimate the percentage of all cars that may be unsafe, we can use the proportion of cars with safety violations found at the auto checkpoint. We can calculate the percentage by dividing the number of cars with safety violations by the total number of cars stopped, and then multiplying by 100.

In this case, 14 of the 134 cars stopped had safety violations. So, the percentage of cars that may be unsafe is (14/134) x 100 = 10.45% (rounded to two decimal places).

Therefore, we can estimate that approximately 10.45% of all cars may be unsafe based on the data from the auto checkpoint.

Ned has scored 84 points in the first 6 games of the basketball season. How many points per game has Ned scored?

Answers

Ned must have scored an avg. of 14 points per game in his 6 games total.
A good strategy to show this is using ratios or proportions.

84 points : 6 games =  14 points : 1 game

SCALE FACTOR: To figure out the scale factor divide the information that is matched. In this case it would be 6 games divided by 1 game. Your scale factor is 6. Multiply the information that matches the information that is missing. So, in this case it would be 84 points divided by 6. You are dividing because you want to know how much Ned scored in one game, now if you wanted to know how much Ned made in 12 games you would multiply 84 by 6. 84 divided by 6 = 14
