Can anyone figure this out

Answer:

b is the correct answer

Option B situations do the quantities combine to make 0.

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: a=56/15

Step-by-step explanation:

For this problems, it is important ot know how to read ratios. They can be read as fractions. Knowing this, we would use proportions to solve.

[tex]\frac{3a}{7} =\frac{8}{5}[/tex]                      [cross multiply]

[tex]15a=56[/tex]                  [divide both sides by 15]

[tex]a=\frac{56}{15}[/tex]

Now, we know that a=56/15.

Answer:

3 11/15

Step-by-step explanation:

3a : 7 : : 8 : 5

= 3a/7 = 8/5

=15a = 56

= 56/15 = 3 11/15

Answer:

4

Step-by-step explanation:

1) First, distribute the negative sign to the -7. Because of this, the -7 will become a positive 7.

Equation: -3+7

2) Next, whenever there are two different signs, we are supposed to subtract the bigger number (7) with the smaller number (3).

Equation: 7-3=4

3) Finally, assign the greatest number sign. in this case, 7 is the greater number, and the 7 is a positive number; therefore, it will be a positive 4.

Answer:

No not all right angles are congruent.

Step-by-step explanation:

Triangle BEC is an isosceles triangle.

The angles opposite the congruent sides are equal

x = measure of missing angle

180 = 54 + 2x

Subtract 54 from both sides

126 = 2x

Divide both sides by 2

63 = x

angle EBC and angle C = 63 degrees

Angle EBC and angle EBA are supplementary.

This means they add up to 180 degrees

180 = 63 + EBA

Subtract 63 from both sides

117 = EBA

the measure of a triangle = 180

Therefore,

The measure of angle AEB = 180 - (40 + 117) = 23 degrees

-5|x + 1| = -15

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

Answer: Option C.

Step-by-step explanation:

The given inequality is

[tex]x^3+x^2-6x\geq 0[/tex]

Taking x common, we get

[tex]x(x^2+x-6)\geq 0[/tex]

Splitting the middle term, we get

[tex]x(x^2+3x-2x-6)\geq 0[/tex]

[tex]x(x(x+3)-2(x+3))\geq 0[/tex]

[tex]x(x+3)(x-2)\geq 0[/tex]

Related equation is

[tex]x(x+3)(x-2)=0[/tex]

[tex]x=-3,0,2[/tex]

These three points divide the number line in 4 parts.

Interval       Sign of [tex]x(x+3)(x-2)\geq 0[/tex]      Statement

(-∞,-3)              [tex](-)(-)(-)=(-)[/tex]                           False      

(-3,0)              [tex](-)(+)(-)=(+)[/tex]                            True  

(0,2)              [tex](+)(+)(-)=(-)[/tex]                              False      

(2,∞)              [tex](+)(+)(+)=(+)[/tex]                              True  

So, the solution set is (-3,0) ∪ (2,∞).

Thus, minimum value is –3 and no maximum value.

Therefore, the correct option is C.

Answer:

minimum = –3, no maximum

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]

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

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;

44 * 15 * 11 = 7,260 ways

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:

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.

Thus, the NIS characteristics are chain and unity of command, and information and intelligence management.
