A waiter determines his salary for a week using the formula S = 3.75h + t, where S is his salary, h is the number of hours he works, and t is his total tips. How much does the waiter make if he works 30 hours in a week and makes a total of $538.75 in tips?

Answers

Answer:

$651.25

Step-by-step explanation:

plug your variables into your equation so,

S= 3.75(30)+ 538.75

and solve

S=112.5+538.75

S=651.25

Answer:

$651.25

Step-by-step explanation:

S = 3.75h + t

Given:

h = 30

t = 538.75

Work:

S = 3.75h + t

S = 3.75(30) + 538.75

S = 112.5 + 538.75

S = 651.25

Step-by-step explanation:

because she withdraws every week 55 then the equation is that

Answer:

a. A = 550 - (n55)b. $165.00

Explanation:

a. Amount of remaining dollars = $550 (the initial amount) - (numbers of weeks times $55 that she withdraws weekly)

so the equation is: A = 550 - (n55)

b. using the equation in (a) we can determine the amount of money in Shirley's account after 7 weeks.

A = 550 - (7×55)

A = 550 - 385

A = $165.00

Maya on the beach

On a warm summer day, a little girl named Maya layed on the hot sand with her brother George. George loved the beach and loved the water that went with it. Maya and George would always go to the beach every Saturday and play with the kids they made friends with. Since Maya was older than her brother George and loved him she would always surprise him with his favorite kind of ice cream, chocolate. Maya and George were very different in many ways but they always figured out how to get along. Their parents were so happy that they got along and were like best friends, but one day Maya made a big mistake. Maya accidentally broke George’s favorite toy dinosaur. When George found out he cryed so hard and then got very angry at Maya. Maya said sorry so many times but none of them would heal her brother’s loss. Maya told her mom about this and Maya said that she will pay for a new dinosaur with the money she has been saving for a new bike. Her mom agreed and so Maya went and bought George a new dinosaur. When George saw his new toy he was so happy and hugged his sister Maya. Some time later, Maya and George went back to the beach and got their favorite ice cream as usual. Maya saw that her brother was playing with the dinosaur that she bought him. She instantly got so happy, but when her brother looked over at her and smiled so big, she knew that nothing could replace her baby brother.

a company staff consists of 20 accountants, 12 economists and 4 secretaries. a staff is chosen at random. Find the probability that the staff is an accountant. With solution.​

Answers

Answer:

5/9

Step-by-step explanation:

Number of accountants = 20

Number of economists = 12

Number of secretaries = 4

Total number of Staffs = 20 + 12 + 4 = 36 staffs

Probability = required outcome / Total possible outcomes

Required outcome = number of accountants

Total possible outcomes = total number of staffs

P(selecting an economist) = 20 / 36 = 5 / 9

The probability that the staff is an accountant is 5/9.

Given

A company staff consists of 20 accountants, 12 economists and 4 secretaries. a staff is chosen at random.

Probability;

Probability is defined as the number of observations and total number of observation.

Total number of Staffs = 20 + 12 + 4 = 36 staffs.

The following formula is used to determine the probability;

[tex]\rm Probability=\dfrac{Accountant \ staff}{Total \ number \ of \ staff}[/tex]

Substitute all the values in the formula;

[tex]\rm Probability=\dfrac{Accountant \ staff}{Total \ number \ of \ staff}\\\\\rm Probability=\dfrac{20}{36}\\\\\rm Probability=\dfrac{5}{9}[/tex]

Hence, the probability that the staff is an accountant is 5/9.

What is the theoretical probability of flipping a heads?

Answers

A coin only has two side so you have a 1 out of 2 chance of getting heads. The probability could change depending on how many times you flip.

answer:

50/50

step-by-step explanation:

hi there!

flip a coin a couple of times, most likely get the same number of heads then you will of tails, since a coin has 2 sides and only two equal sides the probability to flip that very coin and it landing on heads is 50 percent same as landing it on tails, we know its 50 percent because 100 percent is the full amount ( no matter how much the coin is worth ) and dividing that by 2 does indeed equal 50 or 50 percent.

i believe that is one of the reasons why before a lot of sport games start off with a coin toss to chose which team plays first because it is a 50/50 chance for each team, making it fair toss

150 is 75% of what number?

Answers

Answer:

200

Step-by-step explanation:

0.75X = 150

X = 200

so 200 is the answer

Answer:

200

150 is 75% of 200

Step-by-step explanation:

150 is 75% of what number

we can change this so it is simpler to understand.

150 = 75% of x

whenever it says "of" it is telling you to multiply

150 = 75% * x

now we simplify

150 = 75/100 * x

150 = 75x/100

*100       *100

15000 = 75x

/75          /75

200  = x

150 is 75% of 200

The sum of two numbers is 52 and the difference is 8. What are the numbers?

Answers

Answer:

22, 30

Step-by-step explanation:

52/2=26

26-4=22

26+4=30

30+22=52

Answer:

30 and 22

Step-by-step explanation:

This can be solved using system of equations

Let x = the bigger number

Let y = the smaller number

The sum of two numbers is 52

x + y = 52

The difference is 8

x - y = 8

x + y = 52

x - y = 8

I will solve using elimination

 (x + y = 52)

+ (x - y = 8)

-----------------------

2x = 60

/2     /2

x = 30

x + y = 52

30 + y = 52

A formula for converting degrees Celsius ( C ) (C) to degrees Fahrenheit ( F ) (F) is given by the formula F = 9 5 C + 32. F= 5 9 ​ C+32. Solve the formula for C C in terms of F.

Answers

Answer:

C = (5F - 160)/9

Step-by-step explanation:

Given:

F = 9/5C + 32

Solve the formula for C in terms of F

F = 9/5C + 32

F - 32 = 9/5C

C = (F - 32) ÷ 9/5

C = (F - 32) × 5/9

= (5F - 160)/9

C = (5F - 160)/9

Find the measure of the exterior angle.

Answers

the sum of all interior angles must be 180, we know that angle t increases by 10 therefore t is equal to 50° and angle t + 20° is equal to 70°

next we can see that the two angles form a 180° angle meaning the measure of the exterior angle is 180° - 70° or 110°

You school plans to collect at least 1500 pairs of socks for the homeless shelter. So far they have collected 183 pairs of socks. There are 4 days left of the sock drive. Write an inequality and solve to represent the average number of pairs of socks to be collected each of the last 4 days.

Answers

Answer: the amount of socks they will collect in four days is less than the amount of socks they plant to collect, in other words 915<1500 socks.

Step-by-step explanation:

If they collect 183 pairs of socks in one day, and there are four days left, then 183 x 5 = 915 (pairs of socks) in five days. They need to collect 1,500 pairs.
