Noah can't wait for lunchtime. Today is taco day! The cafeteria made three times as many beef tacos as chicken tacos and 50 more fish tacos as chicken tacos. They made 945 tacos in all. How many more beef tacos are there than fish tacos? Correct answer with units (if applicable) is worth 2 points; correct answer only is worth 1 point.

Answers

Answer:

308 beef tacos

Step-by-step explanation:

Let chicken tacos = c

Let beef tacos = 3c

Let fish tacos = c + 50

945 = c + 3c + c + 50

Simplify to 945 = 5c + 50

Subtract 50 on both sides and divide 5 to get

chicken tacos = 179

Plug in 179 to beef tacos to get 179*3 = 537

Plug in 179 to fish tacos to get 179 + 50 = 229

Subtract 537-229 to get how many more beef tacos than fish tacos, and so the answer is 308 beef tacos

The price of one pair of shorts is $45.00. There is a 15% discount if you purchase four or more pairs. What is the total cost, before tax, for six pairs of shorts? (1 point)
O $180.00
$205.50
$229.50
$235.50

Answers

Answer:

$229.50

Step-by-step explanation:

Given;

The price of one pair of shorts is $45.00.

There is a 15% discount if you purchase four or more pairs

To FInd;

What is the total cost, before tax, for six pairs of shorts?

Solve:

Since one pair of shorts is $45

Then six pairs of shorts =

$45 x 6 = $270

Now it also says "There is a 15% discount if you purchase four or more pairs". So we buy six pairs thus, it more than four.

Hence,

$270 x 15% = 40.50

$270 - 40.50 = 229.50

Hence, Answer = $229.50

Pam Everett earned gross wages of $378. Pam's deductions were: $28 in federal withholding taxes, 6.2% in Social Security taxes, 1.45% in Medicare taxes, $20.4 in health insurance, and $28 in union dues. Find the total deductions from Pam's gross pay.

Answers

Answer:

Total deductions = $105.317

Step-by-step explanation:

Gross earning = $378

Deductions:

Federal withholding tax = $28

Social security tax = 6.2% of $378 = $23.436

Medicare tax = 1.45% of $378 = $5.481

Health insurance = $28

Total deductions is gotten by summing up all values above

28+23.436+5.481+20.4+28

= $105.317

The difference between gross earning and deductions

= 378-105.317

= $272.683

Whats the difference to 5,673+4,811-2,429

In at least 100 words independently write your response to the statement, "Anyone can do well in math."

Answers

Answer:

I believe that this is true. Anyone can do well in math, not everyone. The main difference being that if EVERYone could, that means every one person in the world, no matter the circumstance, so by saying ANYone, it's saying that however many people in the world want to do it, can do it, if they try and put in the work. Math is not biased against any one person, nor is it  favored for any one person. Any person who studies, or learns it can do well in math. Someone who has never learned anything about math will not do well at all. So, yes, ANYone can do well, but not EVERYone.

Not 100 words, but should do trick if you just add in some extra words between phrases, and substitute some words with one or two synonyms.

There is a competition at the local movie theater for free movie tickets. You must guess
all four employees' ages given a few clues. The first clue is that when added together,
their ages total 106 years. Kirk is twice ten years less than the manager's age, Brian is 12
years younger than twice the manager's age, and Matt is 6 years older than half the
manager's age. What are all four of their ages? It may help to set up four let statements,
one for each employee (including the manager).

Answers

Answer:

Manager = 24

Kirk = 28

Brian = 36

Matt =18

Step-by-step explanation:

Let

The managers age = x

Kirk is twice ten years less than the manager's age

Kirk = 2(x - 10)

Brian is 12 years younger than twice the manager's age

Brian = 2x - 12

Matt is 6 years older than half the

manager's age.

Matt = 1/2x + 6

Total = 106 years

Add the four employees ages

x + 2(x-10) + (2x-12) + (1/2x + 6) = 106

x + 2x - 20 + 2x - 12 + 1/2x + 6 = 106

5x + 1/2x - 26 = 106

10x+x/2 = 106 + 26

11/2x = 132

x = 132 ÷ 11/2

= 132 × 2 / 11

= 264 / 11

= 24

x = 24

Managers age = x = 24 years

Kirk = 2(x - 10)

= 2(24 - 10)

= 2(14)

= 28 years

Brian = 2x - 12

= 2(24) - 12

= 48 - 12

= 36 years

Matt = 1/2x + 6

= 1/2(24) + 6

= 12 + 6

= 18 years

Using linear function concepts, it is found that the unit rate in dollars per square yard is of $1.35 for Company A and of $2.05 per Company B.

What is a linear function?

A linear function is modeled by:

[tex]y = mx + b[/tex]

In which:

m is the slope, which is the rate of change, that is, by how much y changes when x changes by 1.b is the y-intercept, which is the value of y when x = 0.

In this problem, for company A, the function is:

A: C = 1.35y + 100.

For company B, the function is:

B: C = 2.05y.

Considering the slopes, the unit rate in dollars per square yard is of $1.35 for Company A and of $2.05 per Company B.

During a heavy storm, rain falls for 4.2 hours through the night. A weather station monitors the rain by measuring the milliliters of water it takes to fill a container. How many milliliters of rain will fill the container if the rain falls at a rate of 3 quarts per 39 minutes? Round to one decimal.

Answers

Answer: 18,359.2 mL

Step-by-step explanation:

We know that the rain lasted for 4.2 hours.

Each hour, has 60 minutes.

Then the time of the rain was = 4.2*60min = 252 min.

Now, we know that the rate of the rain is 3 quarts per 39 minutes.

Then the total amount of rain, in quarts, will be:

R = (252min/39min)*3 quarts = 19.4 quarts.

But we want this answer in milliliters, then we can use the relation:

1 quart = 946.353 mL

Then 19.4 quarts are equal to: 19.4*(946.353 mL) = 18,359.2 mL
