Which of the following options have the same value as
65% of 20?
Choose 2 answers:
Answer:
A) 0.65 · 20
D) [tex]\mathsf{\dfrac{65}{100} \cdot 20}[/tex]
Step-by-step explanation:
To find 65% of 20:
Method 1
65% in decimal form is: 65% = 65/100 = 0.65
Therefore, to find a percentage of a number, multiply the percentage in decimal form by the number:
[tex]\mathsf{\implies 65\% \ of \ 20 = 0.65 \cdot 20}[/tex]
Method 2
Divide the number by 100 to get 1%, then multiply this by 20 to get 20%.
[tex]\mathsf{\implies \dfrac{65}{100} \cdot 20}[/tex]
~The word "of" stands for multiplication.~
65/100 × 20 [65% = 65/100]Step-2: Verify all the optionsOption A) 0.65 × 20
~0.65 can be converted to fraction, which is 65/100.~
⇒ 65/100 × 20 = 65/100 × 20 [0.65 = 65/100]~This expression correctly matches with the resulting expression.~
Thus, option A is correct.
Option B) 65/100 ÷ 20
⇒ 65/100 ÷ 20 = 65/100 × 20This could've been equivalent to the resulting expression. However, the expression has a division sign.
Thus, Option B is incorrect.
Option C) 65/20 × 100
~To avoid confusion, let's further solve the expression.~
65/20 × 100⇒ 65/1 × 5⇒ 325~Now, let's solve the resulting expression.~
65/100 × 20⇒ 65/100 × 20⇒ 65/5 × 1⇒ 13~Since 13 does not equal 325, "65/20 × 100" does not equal "65/100 × 20".~
Thus, option C is incorrect.
Option D) 65/100 × 20
~This equation is the resulting equation.~
Thus, option D is correct.
Option E) 65 × 20
~To avoid confusion, let's further solve the expression.~
65 × 20 ⇒ 650 × 2⇒ 1300~Now, let's solve the resulting expression.~
65/100 × 20⇒ 65/100 × 20⇒ 65/5 × 1⇒ 13Since 1300 does not equal 13, 65 × 20 does not equal 65/100 × 20.
Thus, option E is incorrect.
Step-3: Make a conclusionOption A and D were equivalent to 65/100 × 20.

Step-by-step explanation:
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

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

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

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

Find the ratio of the volume divided by the temperature for the first data pair. Use significant figures. V / T = 0. 72/276 =.
The ratio of the volume divided by the temperature for the first data pair is 0.0026 using the significant figures.
What is a ratio of two numbers?The ratio of two number is the fraction part, which represent that how a number is more or less compare to the other.
The value of the volume is 0.72 and the value of temperature is 276 for the first data pair. The image of all the values of the volume and temperature table is attached below.
The ratio of the volume to the temperature is,
[tex]\dfrac{V }{ T} =\dfrac{ 0. 72}{276 }\\\dfrac{V }{ T} =0.002608695652[/tex]
The above value is the ratio of volume to the temperature. Now this value has to be written with significant figure.
Let's correct the value, after the 4 places of the decimal point. As the value of fifth place is zero, then the value of 4 place will remain as it is.
Thus, the ratio is,
[tex]\dfrac{V }{ T} =0.0026[/tex]
The ratio of the volume divided by the temperature for the first data pair is 0.0026 using the significant figures.

Formula for volume of a sphere: 4/3 x pi x radius cubed
Substitute: 4/3 x pi x 1.5 cubed
= 14.1
Answer:
14.13
Step-by-step explanation:
Sphere formula;
v = 4/3πr^3
Where pi is 3.14 or 22/7
R is the radius which is cubed
Substitute the radius(1.5) into the formula:
v = 4/3πr^3
v = 4/3 * 3.14 * 1.5^3
v = 4/3 * 3.14 * 3.375
v = 4/3 * 10.5975
v = 42.39/3
v = 14.13, our closest answer would be D.

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.
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]
