15% markup

Step-by-step explanation:

5% markup would be $1. Since 20*5% or 20*.05=1

We can multiply it by 3 to find the percent for $3 markup. Which is 15% or 0.15

Answer:

x=30

Step-by-step explanation:

2x+x+90=180 (anglesome prop.)

Answer:

x=12

Step-by-step explanation:

11x-3 + 5x-9 = 180

16x -12 = 180

16x = 192

x = 12

Answer: -51 and -73

Step-by-step explanation:

Let the first number be x.

Let the second number be x-22.

Since the sum of two numbers is -124, this means that:

x + x - 22 = -124

2x - 22 = -124

2x = -124 + 22

2x = -102

x = -102/2

x = -51

Since the second number is x - 22. This will be:

= x - 22

= -51 - 22

= -73

The numbers are -51 and -73

Answer:

Step-by-step explanation:

1). y = - 4x + 7

Reflected across what????

if x-axis, then y ⇒ - y

So the answer would be y = 4x - 7

2). y = 2x - 14

3). y = 2x - 8

4). y = 12x + 9

Answer:

Yes he does

Step-by-step explanation:

that would be 4/3

4/3 < 1 1/4

Step-by-step explanation:

Answer:

0.167

Step-by-step explanation:

Arrival time of the bus = 30 minutes

We have to find the probability of waiting between 25 to 30 minutes.

From this we have that,

a = 0

b = 30

The solution can be expressed as;

P(25<x<30) = (30 - 25) / (30 - 0)

P(25<x<30) = 5/30

P(25<x<30) = 0.167

0.167 is the probability of waiting between 25 minutes and 30 minutes.

Answer:

(-1/3x5/2x(-9)

Answer:

50 feet

Step-by-step explanation:

The car's distance from the timekeeper us given by :

y = 293x+50

Where x is time in seconds and y is the distance from the timekeeper's position.

The general equation of a line is given by :

y = mx +c

On comparing, we get : c = 50

It means the timekeeper has covered 50 feets at the beginning.

Answer:

the probability that exact three would be replaced under each warranty is 0.34

Step-by-step explanation:

The computation of the probability that exact three would be replaced under each warranty is as follows

Given that

Submitted under warranty = P = 20%

Replaced with the new units = 40%

So replaced and submitted would be

= 40% × 20%

= 80%

Now let us assume the number of telephones be x for ending up for replacement

Total number of telephones purchased is 10

Now the probability by applying the formula of binomial probability is

[tex]P(X) = n_C_xp^x(1 - p)^{n-x}[/tex]

[tex]P (X = 3) = ^{10}C_3(0.08)^3 (1 - 0.08)^{10 - 3}\\\\= \frac{10!}{3!(10! - 3!)} (0.08)^3(0.92)^7\\\\[/tex]

= 0.34

Hence, the probability that exact three would be replaced under each warranty is 0.34

Answer:

1.2

Answer:

[tex] \dfrac{580}{9} [/tex]

Step-by-step explanation:

[tex] \dfrac{1}{5}x + \dfrac{1}{4}x = 29 [/tex]

[tex] \dfrac{4}{20}x + \dfrac{5}{20}x = 29 [/tex]

[tex] \dfrac{9}{20}x = 29 [/tex]

[tex] x = 29 \times \dfrac{20}{9} [/tex]

[tex] x = \dfrac{580}{9} [/tex]

Answer: [tex] \dfrac{580}{9} [/tex]

Step-by-step explanation:

2.50h+10=31.25

because

2.50*h tells you how much you pay for the hours the dogs is at the daycare

10 is you pay for pick-up

31.25 is your total

Answer:

9 and 12

Step-by-step explanation:

Pythagorean Theorem. One of the most common Pythagorean triples is 3, 4, 5 with 3 and 4 the legs and 5 the hypoenuse. That will make 9, 12, 15 anotther trible because you are tripling the side lengths. 12-9=3 so this triangle works.

Answer:

Each man would have to work 7.2 overtime hours per day if they wanted to meet the goal.

Step-by-step explanation:

If 200 men can make a 3 km long embankment in 25 days, their work day being 12 hours, to determine the amount of work that each one does, the following calculation must be made, taking into account that 3 km is the same at 3,000 meters:

3000/25 = 120 meters per day

120/200 = 0.6 meters per day per man

0.6 / 12 = 0.05 meters per hour worked per man

Therefore, to determine the extra work time that 60 men should carry out, if they wanted to complete a 2 km long embankment in 32 days, the following calculation should be performed:

2000/32 = 62.5 meters per day

62.5 / 60 = 1.04 meters per day per man

1.04 / 12 = 0.08 meters per hour worked per man

Therefore, that difference of 0.03 meters must be taken into account to determine the extra time of work that these men must carry out, carrying out the following cross multiplication:

0.05 = 12

0.08 = X

((0.08 x 12) / 0.05) = X

(0.96 / 0.05) = X

19.2 = X

Therefore, each man would have to work 7.2 overtime hours per day if they wanted to meet the goal.

Answer:

14x² + 7y - 22

Step-by-step explanation:

Combine like terms.

5x² - 6y - 22 + 13y + 9x²

5x² + 9x² = 14x²

-6y + 13y = 7y

Reorder the terms.

14x² + 7y - 22
