Answer:
x = 5/2
Step-by-step explanation:
Solve for x:
(5 x)/2 = 25/4
Hint: | Multiply both sides by a constant to simplify the equation.
Multiply both sides of (5 x)/2 = 25/4 by 2/5:
(2×5 x)/(5×2) = 2/5×25/4
Hint: | Express 2/5×5/2 as a single fraction.
2/5×5/2 = (2×5)/(5×2):
(2×5)/(5×2) x = 2/5×25/4
Hint: | Express 2/5×25/4 as a single fraction.
2/5×25/4 = (2×25)/(5×4):
(2×5 x)/(5×2) = (2×25)/(5×4)
Hint: | Cancel common terms in the numerator and denominator of (2×5 x)/(5×2).
(2×5 x)/(5×2) = (5×2)/(5×2)×x = x:
x = (2×25)/(5×4)
Hint: | In (2×25)/(5×4), divide 25 in the numerator by 5 in the denominator.
25/5 = (5×5)/5 = 5:
x = (2×5)/4
Hint: | In (2×5)/4, divide 4 in the denominator by 2 in the numerator.
2/4 = 2/(2×2) = 1/2:
Answer: x = 5/2
quotient of twice a number and 6 is 42
Answer:
[tex]n = 126[/tex]
Step-by-step explanation:
First let's model this into an equation.
Twice a number is [tex]2n[/tex], and that divided by 6 is [tex]\frac{2n}{6}[/tex]. That's equal to 42, so we have [tex]\frac{2n}{6} = 42[/tex].
Now we can simplify this equation by isolating n on one side of the equation.
Multiply both sides by 6:
[tex]\frac{2n}{6} \cdot 6 = 42\cdot 6\\\\2n = 252[/tex]
Divide both sides by 2:
[tex]2n \div 2 = 252\div 2\\\\n = 126[/tex]

LaVilla is a village in the Italian Alps. Given its enormous popularity among Swiss, German, Austrian, and Italian skiers, all of its beds are always booked in the winter season, and there are, on average, 1465 skiers in the village. On average, skiers stay in LaVilla for 11 days. How many new skiers are arriving - on average - in LaVilla every day
Answer:
There are approximately 133 new skiers arriving every day
Step-by-step explanation:
Total number of skiers = 1465
time of stay for skiers = 11 days
How many new skiers are arriving on average = ???
To keep the average number of skiers available at each time constant, the number of skiers coming in and going out are fairly constant, and this is gotten by using the flow rate formula.
flow rate = amount available ÷ flow time
flow rate = 1465 ÷ 11
flow rate = 133.18
flow rate = 133
∴ There are approximately 133 new skiers arriving every day

In 2016 49% of all degrees granted were bachelors degrees if 1,920,718 students earned bachelors degrees how many total degrees were granted that year
Answer:
3919832.65306Step-by-step explanation:
This problem is focused on percentages.
Now given that 49% of a number is 1,920,718
we can say let the number be x
so 49% of x= 1,920,718
now expressing this problem mathematically we have
(49/100)*x= 1,920,718
0.49x= 1,920,718
divide both sides by 0.49 we have
x= 1,920,718/0.49
x= 3919832.65306
Therefore the total that were granted degree that year was 3919832.65306

What are arithmetic operators?Arithmetic operations are a set of four basic operations to be performed to add, subtract, multiply or divide two or more quantities. These are also known as mathematical operations.
Addition
The addition is a basic mathematical skill of finding or calculating the total of two or more numbers, or we can say in simple words adding things together. It is denoted by the symbol ‘+’.
Subtraction
The subtraction arithmetic operation shows the difference between two numbers. It is denoted by the symbol ‘-‘. Subtraction is mostly used to find out what is left when things are taken away.
Multiplication
The repeated addition is known as multiplication. It is represented by the symbol ‘×’. Multiplication as an arithmetic operation helps us to find out the total when a number is repeating itself a number of times.
Division
The division is an act of dividing something into equal parts or groups. It is one of the four basic arithmetic operations which gives a fair result of equal sharing.
Option A :
Given
A bird flies 25 feet up in the air. It then flies 25 feet across to its
nest.
So, total distance flown by bird = 25 + 25 = 50 feet
Which do not combine to 0.
Option C :
A player in a game earns 4 points for getting an answer right. She
then earns 4 points for making it around the board.
Hence, total points earned = 4 + 4 = 8
Which do not combine to 0.
Option D :
A car is filled with 10 gallons of gas, Half of the 10 gallons are
then used on a day's drive.
= 10 - [tex]\frac{1}{2}[/tex] × 10
= 10 - 5
= 5
Which do not combine to 0.
Option B :
Veronica receives $21 for babysitting. She then spends $21 on a
new shirt.
So net amount left with Veronica = 21 - 21 = 0
Hence, it combines to zero.

Answer: Chain of Command and Unity of Command ; Information and Intelligence Management
Step-by-step explanation:
Chain of Command typically loooks into an organization's hierarchical structure while unity of commands simply has to do with the reporting to ones designated supervisor.
Also, because maps are being produced, there'll be with the gathering, assessing, analyzing, sharing, and managing intelligence.
Therefore, the NIMS Management Characteristics that'll be supported are Chain of Command and Unity of Command ; Information and Intelligence Management.
The NIMS management characteristics that are mostly supported are:
A chain of Command is a unity of command.information and intelligence management.The chain of command and unity of command is an overall hierarchy of the orpganization, while the unity of command says that the entire chain is always reporting to the similarly designated supervisor.
The information and intelligent management help the owner to take according to decisions forward premises of the information system.
As per the GIS when the maps have the process for the information would be gathering the information, assessing it, analyzing it, sharing the information to the delegated conducting the field, and then managing the intelligence of the information.

Suppose there are 11 freshman, 7 sophomores, 13 juniors, and 15 seniors running for the offices of president, vice president, and secretary. If no person can hold more than one office, in how many different ways could these people be elected to these positions if the president must be a senior and the secretary must be a freshman
Answer:
7,260 ways
Step-by-step explanation:
Here, we are told that the president must be a senior and the secretary must be a freshman.
Now for the post of President, we have 15 choices to pick from
For the post of secretary, we have 11 choices to pick from
Now the last position, the vice president
Firstly , we have 14 seniors( 1 already president), 10 freshmen(1 already secretary) , 6 sophomores and 13 juniors
So the total number of choices will be;
14 + 10 + 7 + 13 = 44
So the number of ways will be;

what is the value of x in the equation as a fraction 2(5x+4)=17
Answer:
x= 9/10
Step-by-step explanation:
2(5x+4)=17
Distribute
10x +8 = 17
Subtract 8 from each side
10x+8-8=17-8
10x = 9
Divid by 10
10x/10 = 9/10
x= 9/10
Divide both sides by 2:
5x + 4 = 8.5
Subtract both sides by 4:
5x = 8.5 - 4 = 4.5
Divide both sides by 5:
x = 4.5 / 5 = 0.9 or 9/10

The distance between the endpoints of line segment XY will be 15.2 units.
What is the distance between two points?It is the measure of distance between the two points and is known as length. The length is measured in meters generally.
Let one point be (x, y) and another point be (h, k).
Then the distance between the points will be
D² = (x - h)² + (y - k)²
The endpoints of line segment XY are given below.
X(-9, 2) and Y(5, -4)
The distance between the endpoints of line segment XY will be given as,
D² = (x - h)² + (y - k)²
D² = (5 + 9)² + (-4 - 2)²
D² = (14)² + (-6)²
D² = 196 + 36
D² = 232
D = √232
D = 15.2 units
The distance between the endpoints of line section XY will be 15.2 units.
