y= 19/3x+3

solution: i just finished this unit in class

Answer:

I think 0.15b would be a no because that is just what a customer would tip.

15b is also a no because that is 15 times the price of the bill.

b + 0.15b is a yes because you are adding the bill and 15% of the bill as a tip.

1.15b is a no because you are multiplying the bill by 1.15.

1.015 is a no because you're multiplying the bill by 1.015.

b + (15/100)b is a yes because you are adding the bill and 15% out of 100% of the bill as a tip.

b + 0.15 is a no because you would be tipping them 15 cents, not 15% of the bill.

Answer:

P = 0.886 (88.6%)

Step-by-step explanation:

Of the 44 students there are 5 who do not apply to be chosen

[tex]P=\frac{44-5}{44} =\frac{39}{44} =0.886[/tex]

P = (0.886)(100) = 88.6%

After 99 days, Karen is required to pay $14,436.63 in full, plus $139.63 in interest.

What is simple interest?

Simple interest is calculated based on a loan's principal or the initial deposit into a savings account. Simple interest doesn't compound, therefore a creditor will only charge interest on the principal sum, and a borrower will never be required to pay further interest on the interest that has already accrued.

Given, Karen obtains a loan for home renovations from a bank that charges simple interest at an annual rate of 3.6%. Her loan is for $14,300 for 99 days.

From the formula of simple interest(SI) :

SI = P * R * T / 100

Where p = principal amount

r = rate of interest

T = time

In our case

p = 14300

r = 3.6

time = 99/365

Simple interest = (14300* 3.6 * 99) / 36500

Simple interest = (143 * 3.6 * 99) / 365

Simple interest = 139.63

The total amount she has to pay = principal amount + SI

The total amount she has to pay = 14300 + 136.63

The total amount she has to pay = 14,436.63

therefore, Karen has to pay $139.63 interest and $14,436.63 Total amount after 99 days.

The arrangement of 26/4, 6.45, 6 2/5, and 50/8 in order from least to greatest is C. 50/8, 6 2/5, 6.45, 26/4.

How can the order be determined?

The concept that will be used here is ordering of numbers using < signs.

To arrange the shows, we can convert 26/4, 6.45, 6 2/5, and 50/8 to decimal so this will help us to determine the order.

26/4=6.50

6.45=6.45

6 2/5=32/5 = 6.40

50/8 =6.25

Then 6.25<6.40 <6.45 <6.50 and this implies that the order that the arrangement follows is 50/8, 6 2/5, 6.45, 26/4

Therefore, option C is correct.

Achilles ran 2 minutes to reach the finish line.

What is Speed?

Speed is the unit rate in terms of distance travelled by an object and the time taken to travel the distance.

Speed is a scalar quantity as it only has magnitude and no direction.

Let d be the total distance in miles from the starting line to finish line.

Let t be the time taken to complete the distance by Achilles.

Speed = Distance / Time

Speed of Achilles = 13 mph

13 = d / t ⇒ t = d / 13

Speed of Turtle = 1 mph

In the same time t, Turtle is 2/5 of a mile behind Achilles.

1 = (d - 2/5) / t ⇒ t = d - 2/5

We have t = d / 13 and t = d - 2/5

d / 13 = d - 2/5

d = 13 (d - 0.4)

d = 13d - 5.2

12d = 5.2

d = 0.43333 mile

Now substitute the value of d in the equation t = d / 13,

t = 0.4333 / 13 = 0.03333 hour = (60 × 0.0333) minutes = 2 minutes

Hence the time taken to reach the finish line by Achilles is 2 minutes.

Answer: 6y + 36

Step-by-step explanation:

= 6y + 36

Answer:

The graphs of y = 3x + 4 and y = 3x + 7 are parallel because their slopes are the same (3).

The graphs of y = 2x - 5 and y = 5x - 5 are neither parallel nor perpendicular because their slopes are not the same (2 and 5).

The graphs of y = 3/5x - 3 and 5y = 3x - 10 are neither parallel nor perpendicular. The first equation is not in slope-intercept form, and the second equation is not in standard form.

The graphs of y = 7x + 2 and x + 7y = 8 are neither parallel nor perpendicular. The first equation is in slope intercept form, but the second equation is not.

The graphs of y = -4x + 1 and 4y = x + 3 are perpendicular because the product of their slopes is -1.

The graphs of y = -1/3x + 2 and y = 3x - 5 are neither parallel nor perpendicular. The slopes are -1/3 and 3, which are not the same, so the lines are not parallel, and their product is not -1, so the lines are not perpendicular.

The graph of y = 4 is a horizontal line and the graph of 4y = 6 is not a function. So, they are neither parallel nor perpendicular.

The graphs of y = 5/6x - 6 and x + 5y = 4 are neither parallel nor perpendicular. The first equation is in slope intercept form, but the second equation is not.

We’ll use the segment addition postulate, which states that we can add two adjacent (next to each other) segments to find the total length.

We are given the total length as segment GI=2x+15, and we will solve for x. So, we can add the two expressions together to equal the length of segment GI.

Let’s form an equation:

GH+HI=GI

Substitute the corresponding values in for GH, HI, and GI:

(3x+8)+(2x+1)=2x+15

Solve for x:

Combine like terms:

(3x+2x)+(8+1)=2x+15

5x+9=2x+15

Subtract 2x from both sides:

5x-2x+9=15

3x+9=15

Subtract 9 from both sides:

3x=15-9

3x=6

Divide both sides by 3:

3x/3=6/3

x=2

Let’s check if this is correct. Substitute x=2 back into the equation:

360°

Step-by-step explanation:

The sum of the exterior angles of any n-gon is 360°

The angles m∠1 = 2x ° and m∠2 = x + 42 ° are complementary angles, and their measures are m∠1 = 32° and m∠2 = 58°.

What are complementary angles

Complementary angles angles are those angles when added together sum up to 90°. That is the sum total of complementary angles is 90°.

m∠1 + m∠2 = 90°

2x° + x + 42° = 90°

3x + 42° = 90°

3x = 90° - 42°

3x = 48°

x = 48°/3

x = 16

Therefore, the complementary angles have their measures to be:

m∠1 = 2(16) = 32°

m∠2 = 16 + 42° = 58°
