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.
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
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).
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

In a class of 27 students, 12 play an instrument and 6 play a sport. There are 13 students who do not play an instrument or a sport. What is the probability that a student chosen randomly from the class plays a sport?
The probability of a student chosen plays a sport is [tex]\frac{6}{27}[/tex]
What is probability?'Probability is the branch of mathematics concerning numerical descriptions of how likely an event is to occur, or how likely it is that a proposition is true. The probability of an event is a number between 0 and 1, where, roughly speaking, 0 indicates impossibility of the event and 1 indicates certainty.'
According to the given problem,
Total number of students = 27
Number of students playing a sport = 6
Number of students playing an instrument = 12
Number of students no playing a sport or instrument = 13
Probability = [tex]\frac{No of possible events}{Total number of students}[/tex]
= [tex]\frac{6}{27}[/tex]
Hence, we can conclude that the probability of a student chosen plays a sport is [tex]\frac{6}{27}[/tex].

The table below shows the combination of a dry prepacked mix and water to make concrete the mix says for every 1 gallon of water stir 60 pounds of dry mix . We know that 1 gallon of water is equal to 8 pounds of water . Using the information provided in the table , complete the remaining parts of the table . What belongs in Cell A?
Answer:
60
Step-by-step explanation:
1 pound of water to 60 pounds of dry mix
If 1 gallon of water = 8 pounds of water, then, we would have,
8 pounds of water to 60 pounds of dry mix
This implies that 8 pounds of water would stir 60 pounds of dry mix. Therefore, in the table showing both possible combinations, what we would have in cell A would be amount of dry mix that would be combined with 8 pounds of water = 60 pounds.
Cell A = 60 pounds

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.
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

You mix soda water, fruit punch concentrate, and ginger ale in the ratio of 1 : 2 : 5 to make fruit punch. How many pints of each ingredient should you use to make 32 pints of fruit punch?
Answer:
So you have the ratio of
1 : 2 : 5
Soda water : fruit punch: ginger ale
You have to make 32 pints of this.
You can add up the ratio.
1 + 2 + 5 = 8
You’d have 8 ingredients in total.
32 pints so 32/8 = 4
Now you have each ingredient *4
1 * 4 = 4
2* 4 = 8
5* 4 = 20
SO 4 soda water, 8 fruit punch, 20 ginger ale.
To check you can add these up again and if they equal 32 then you got it.

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
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

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