Answer:   angle AOB = 40 degrees

====================================================

Explanation:

The smaller angles AOB and BOC combine to the largest angle AOC

By the angle addition postulate, we can say,

(angleAOB) + (angleBOC) = (angleAOC)

(3x+4) + (8x-28) = 108

11x-24 = 108

11x = 108+24 .... adding 24 to both sides

11x = 132

x = 132/11 .... dividing both sides by 11

x = 12

We can use this x value to find each angle

angle AOB = 3x+4 = 3*12+4 = 40 degrees

angle BOC = 8x-28 = 8*12-28 = 68 degrees

As a check,

(angleAOB)+(angleBOC) = (40)+(68) = 108

which matches with the measure of angle AOC. This confirms our answers.

Answer:

[tex]AOB = 40[/tex]

Step-by-step explanation:

[tex]AOC = 108 \\

AOB = 3x + 4 \\

BOC = 8x - 28 \\ but \: AOB +BOC =AOC \\ 3x + 4 + 8x - 28 = 108\\ 11x = 132 \\ x = 12\\ AOB = 3x + 4 = 3(12) + 4 \\ AOB = 40[/tex]

A box contains 6 blue pens and 10 red pens. What is the ratio of red pens to total pens as a fraction​

Answers

Answer: 5/8

Step-by-step explanation: The ratio is 10:16 because total of 16 pens and 10 being red.

The ratio of red pens to total pens as a fraction is 5/8.

What is Ratio?

A ratio is defined as a relationship between two quantities, it is expressed as one divided by the other

The ratio of red pens to total pens can be expressed as a fraction. To find this fraction, we need to divide the number of red pens by the total number of pens.

The total number of pens in the box is 6 blue pens + 10 red pens = 16 pens

So, the fraction representing the ratio of red pens to total pens is:

10/16

It can be simplified by dividing both the numerator and denominator by 2, to get

5/8

So the ratio of red pens to total pens as a fraction is 5/8. This means that out of every 8 pens, 5 are red.

When as rate, 100 miles in 5 hours would be ????? miles per hour

Answers

Answer:

20

Step-by-step explanation:

5 divided by 100 = 20

Answer:

20 miles per hour (20 mi/h)

Step-by-step explanation:

100 miles/5 hours = 20 miles/ 1 hour

(simplify the proportion)

Consider the following formula s=d/t, with

s being the speed, d as the distance, and t as the time.

this is because miles per hour is a measurement of speed.

In this case, 100 miles is the distance. 5 hours is the time, and we are solving for s.

s = 100/5, s = 20/1, s = 20 which is 20. So the rate or the speed is 20 miles per hour.

Anything multiplied or divided by 1 will remain the same.

A local sporting goods store is planning to hire up to 24 temporary employees for its annual Black Friday Sale. Experienced workers (x) will be paid $20 per hour and produce 1.5 times the profit that an inexperienced worker produces. Inexperienced workers (y) get hired at $15 per hour. The store can pay up to $400 per hour for the temporary employees. How many of each type of worker can be hired to maximize profit?

Answers

Answer:

8 experienced workers and 16 inexperienced workers

Step-by-step explanation:

Let x represent the number of experienced workers, y represent the number of inexperienced workers.

The store can hire up to 24 temporary employees, hence:

x + y ≤ 24

The store can pay up to $400 per hour, hence:

20x + 15y ≤ 400

Also, x, y > 0

The solution to the above problem is at (8, 16). Hence x = 8 and y = 16.

The profit of an experienced worker is 1.5 times the profit that an inexperienced worker. hence:

Profit = 1.5x + y

Profit = 1.5(8) + 16

Profit = 12 + 16 = 28

Evaluate x ÷ y for x = 3 and y = 12.

Answer:

If 15% of x is 42, what is x?

Answers

If the part is 42 then the X is going to be 280

The required whole value of x is 280 if 15% of x is 42.

What is the percentage?

The percentage is defined as a ratio expressed as a fraction of 100.

For example, If Misha obtained a score of 67% on her exam, that corresponds to 67 out of 100. It is expressed as 67/100 in fractional form and as 67:100 in ratio form.

To determine the value of x, we can set up the equation: (15/100)x = 42.

This equation states that 15% of x is equal to 42.

To solve for x, we can divide both sides of the equation by (15/100) to get:

x = (100/15) × 42

x = 280

So x = 280.

This means that if 15% of x is 42, then the whole value of x is 280.
