Answer:

43 points

Step-by-step explanation:

let the score of cowboys is x

and giants make score 9 which is twice less than the cowboys score so

giants score will be = 2x -9

and packers scored 14 more than giants that is (2x - 9) + 14

now sum of their scores is equal to 81 it means:

x + (2x - 9) + (2x -9) + 14 = 81

x + 2x - 9 + 2x - 9 + 14 = 81

5x = 81 + 4

5x = 85

x = 17

packers scored =  (2x - 9) + 14

= 2 (17) -9 + 14

=38 + 5 = 43 points

Explanation:

Consider the set

[tex]\left\{x_1,x_2,x_3,\ldots,x_n\right\}\\\\[/tex]

which has n items in it. We don't know anything about any individual item, but what we do know is that the mean is S.

So,

[tex]\text{mean} = \frac{\text{sum of values}}{\text{number of values}}\\\\\text{mean} = \frac{x_1+x_2+x_3+\ldots+x_n}{n}\\\\S = \frac{x_1+x_2+x_3+\ldots+x_n}{n}\\\\nS = x_1+x_2+x_3+\ldots+x_n\\\\x_1+x_2+x_3+\ldots+x_n = nS\\\\[/tex]

In short, the sum of the values [tex]\left\{x_1,x_2,x_3,\ldots,x_n\right\}\\\\[/tex] is exactly nS, where S is the mean of the same set.

------------------------

Next, we add 1 to [tex]x_1[/tex], add 2 onto [tex]x_2[/tex], etc to form this new set

[tex]\left\{x_1+1,x_2+2,x_3+3,\ldots,x_n+n\right\}\\\\[/tex]

Let's find the mean like so

[tex]\text{mean} = \frac{\text{sum of values}}{\text{number of values}}\\\\\text{mean} = \frac{(x_1+1)+(x_2+2)+(x_3+3)+\ldots+(x_n+n)}{n}\\\\\text{mean} = \frac{\left(x_1+x_2+x_3+\ldots+x_n\right)+\left(1+2+3+\ldots n\right)}{n}\\\\\text{mean} = \frac{nS+0.5n(n+1)}{n}\\\\\text{mean} = \frac{n(S+0.5(n+1))}{n}\\\\\text{mean} = S+0.5(n+1)\\\\[/tex]

which is why S+0.5(n+1) is the answer

------------------------

Let's look at a concrete example.

Consider the set {1,7,10} which has n = 3 items in it.

Its mean is,

S = (1+7+10)/3 = 18/3 = 6

Now increase the items in {1,7,10} by adding on the values {1,2,3} to each element in the order shown

1+1 = 2

7+2 = 9

10+3 = 13

So {1,7,10} becomes {2,9,13}

The mean of the new set {2,9,13} is...

mean = (2+9+13)/3 = 24/3 = 8

Notice how,

newMean = S + 0.5(n+1)

newMean = 6 + 0.5(3+1)

newMean = 8

which helps us see how the formula works and partially confirm the answer. While this example isn't definitive proof, it's still handy to go over. I recommend forming other sets to check to see that this formula works. Not only do I recommend trying different values, but also a different number of values as well (i.e. increase n to some larger integer).

Answer:

1st Q: C. Algebraic Expression; it consists of numbers and a variable.

2nd Q: D. The number of times Chris washes the car.

Step-by-step explanation:

1st Question:

Numerical Expression: Contains numbers and operations. Numerical expressions are your typical 2 + 2 equations. The ones you start learning in Kindergarten with just numbers and different operations such as addition, subtraction, division, and multiplication.

EX: 108 - 24 = ?

? = 84

Algebraic Expression: Contains numbers, operations, and variables. They are the same as normal, numerical expressions with the exception that it also has letters, or variables.

EX: 2x + 3 = 7

x = 2

__________________________________

2nd Question:

Amount Chris earns per wash: $10.00

# of times Chris washes the car: x

So 10x means what...?

10 = earns per wash

x = times washed the car

Multiply 10 by x to find the total Chris earns for the number of times he washes the car, x.

(Just as a reference, this would be counted as an Algebraic Expression).

Hope this helps! :)

Answer:

3 : (1/2) =[tex]\frac{6}{1} =6[/tex]

Step-by-step explanation:

Divide: 3 : [tex]\frac{1}{2} =\frac{3}{1} *\frac{2}{1} =\frac{3 * 2}{1*1} =\frac{6}{1} =6[/tex]

Dividing two fractions is the same as multiplying the first fraction by the reciprocal value of the second fraction. The first sub-step is to find the reciprocal (reverse the numerator and denominator, reciprocal of [tex]\frac{1}{2}[/tex] is [tex]\frac{2}{1}[/tex]) of the second fraction. Next, multiply the two numerators. Then, multiply the two denominators.

In words - three divided by one half = six.

El área de las tierras de Juan es el producto del largo y ancho de cada pieza, por lo que el área de sus tierras son 19.9375 m² y 90.250 m² respectivamente.

El Área de las tierras de Juan se puede calcular así:

Área = largo × ancho

Tierra 1:

Dimensión = 7 ¼ metros por 2 ¾

Área de terreno 1 = 7 ¼m × 2 ¾m = 19.9375 m²

Tierra 2:

Dimensión = 9,50 metros por 9,50 metros

Área de tierra 2 = 9.50 × 9.50 = 90.250 m²

Por tanto, la superficie de los terrenos de Juan es de 19,9375 m² y 90,250 m² respectivamente.

The last option: x > -2 and x < 5

Step-by-step explanation:

First of all we look at the circles at the end.

Both are open circles, which indicates that -2 and 5 are not included.

Reading left to right, x is greater than -2 (remember, not greater than or equal to)

And x is less than 5 (not including 5)

Answer:

200<=15x

divide by 15

You have to work at least 13 1/3 hours to earn $200

<= means greater than or equal to

Step-by-step explanation:

The minimum number of hours to earn at least $200 is 14

Let the number of hours be x.

Given that hourly rate is $15, and he needs to earn at least $200;

The inequality of the scenario is:

15x >= 200

Divide both sides by 200

x >= 13.33

The smallest integer greater than 13.33 is 14.

So, we have:

x = 14

Hence, the minimum number of hours is 14

Answer: 37 percent of waste is disposed of in some form of a landfill, 8 percent of which is disposed of in sanitary landfills with landfill gas collection systems

The U.S. is the king of trash, producing a world-leading 250 million tons a year—roughly 4.4 pounds of trash per person per day Collectively, out of the 254 million tons of trash Americans can produce in one year, we recycle about 34.3 percent of it. For our average individual, 710.6 pounds are recycled and 1,361.4 pounds of trash are tossed out every year — about the weight of a grizzly bear Every year, U.S. landfills are filled with 139.6 million tons of waste, including 30.63 million tons of food. 26.82 million tons of plastic. 18.35 million tons of paper and paperboard.

Answer:

x-intercept = 6.2 , y-intercept = 3.1

Step-by-step explanation:

First turn 2x + 4y = 12.4 to slope-intercept form (y = mx + b) where m is slope and b is y-intercept.

Subtract 2x on both sides to move it to the other side, and get 4y by its self. Now it looks like 4y = -2x + 12.4 (since 2x and 12.4 aren't like terms, you wouldn't combine them).

Next, divide 4 on both side to get rid of it, and to get y by its self. Now you'll have

y = -2/4 x + 3.1 (since 12.4 can be divided by 4, that's how you get 3.1). You can already tell, just by looking at

y = -2/4 x + 3.1 , that the y-intercept is 3.1

Now we graph, to find out what the x-intercept is. I did it for you above.⤴⤴⤴

Step-by-step explanation:

Area of a curved surface of a cylinder = 4400 cm².

The circumference of its base = 110 cm.

As we know that,

Formula of : circumference of base = 2πr.

→ 2πr = 110.

→ πr = 55.

Formula of : Curved surface area of cylinder = 2πrh.

→ 2πrh = 4400.

Put the value of πr = 55 in the equation, we get.

→ 2(55)h = 4400.

→ 110h = 4400.

→ h = 40 cm.

Height of cylinder = 40 cm.

Answer:

Step-by-step explanation:

The inequality expression of the statement is |2s - 7| >= -1

Inequality expressions are mathematical statements that are represented by variables, coefficients and operators where the opposite sides are not equal

The mathematical statement is given as

|2s - 7| is bigger than or equal to -1

The term "bigger than or equal" means greater than or equal to

In mathematics, the term greater than or equal to is represented as >=

So, we have the representation of the mathematical statement to be

|2s - 7| >= -1

From the question, we are not instructed to simplify the expression

This means that we leave the expression |2s - 7| >= -1 unsimplified

Hence, the mathematical statement as an expression is |2s - 7| >= -1
