Answer:

The fraction of the entire mail each person address = 1/8

Step-by-step explanation:

Given that:

number of people addressing envelopes = 6

If they gave out 3/4 of an entire mailing address.

Then, the amount of mailing not addressed is:

= 1 - 3/4

= [tex]\dfrac{4-3}{4}[/tex]

= 1/4

If 6 people shared 3/4 of an entire mailing to address evenly.

Then: each person gets:

[tex]=\dfrac{3}{4} \div 6[/tex]

[tex]=\dfrac{3}{4} \times \dfrac{1}{ 6}[/tex]

= 1/8

The fraction of the entire mail each person address = 1/8

Answer:

It is the total cost of housing and plane tickets for four years.

Step-by-step explanation:

Mark's costs for tuition, technology fee, and books are all per semester, s. ($2,600 + $150 + $310)s = $,060s

The cost for housing and plane tickets are a once a year cost. Mark pays these amounts once a year for four years.4($5,600 + $289) = $23,556

Therefore, the constant in the expression is $23,556, and it is the total cost for housing and plane tickets for four years.

Answer:

[tex]\huge\boxed{2x^4 + 8x^3 + x^2 + 3x}[/tex]

Step-by-step explanation:

When we multiply a polynomial by a specific monomial, all terms in the polynomial get multiplied by the monomial.

So we can do this by term.

[tex]2x^3 \cdot x[/tex]

Multiplying x by x to the something power will just increase the exponent on the x term by one (since powers are just x multiplied by itself). This means the exponent here will increase by 1, so this becomes [tex]2x^4[/tex].

Same logic applies to the second term: [tex]8x^2[/tex], raise the exponent by one, [tex]8x^3[/tex].

For the third term, if there is no exponent on a term you can assume it's exponent is 1 (so [tex]x^1[/tex] in this case - as [tex]x^1=x[/tex]). Again, using the same logic, this turns into [tex]x^2[/tex].

For the last term, when we multiply a constant by a variable, we get a term with a variable and a coefficient - the constant becomes the coefficient and the variable stays the variable. Therefore, [tex]3 \cdot x = 3x[/tex].

Adding these terms all together gets us [tex]2x^4 + 8x^3 + x^2 + 3x[/tex].

Answer: C.  [tex]\dfrac{1}{3}[/tex]

Step-by-step explanation:

Given: Box contains 8 green balls and 4 purple balls.

Total balls = 8+4 = 12

event 1 = first picking green ball

event 2 = second picking purple balls.

As first ball was replaced, that means both events are independent.

Probability that you have selected a green ball and then a purple ball = P(purple ball )

Formula for probability = [tex]\dfrac{\text{favorable outcomes}}{\text{total outcomes}}[/tex]

Probability of selecting a purple ball (second pick)= [tex]\dfrac{4}{12}[/tex]

[tex]=\dfrac{1}{3}[/tex]

The required probability [tex]=\dfrac{1}{3}[/tex], so C is correct option.

Answer:

2/9

Step-by-step explanation:

PJ= PG * PP = 2/3 * 1/3 = 2/9

Answer:

1. The system of equations is given as follows;

S + L = $1,300................(1)

S + 2·C = $1,400............(2)

S + L + C = $1,600.........(3)

Where;

S = The cost of a sofa

L = The cost of a love sea

C = The cost of a single chair

2. The cost of a love sea, L is $500

Step-by-step explanation:

1. The given information are;

The price of sofa and love sea = $1,300

The price of sofa and two chairs = $1,400

The price of sofa, love sea, and one chair = $1,600

Let the cost of a sofa = S

Let the cost of a love sea = L

Let the cost of a chair = C

Therefore, we have;

S + L = $1,300................(1)

S + 2·C = $1,400............(2)

S + L + C = $1,600.........(3)

2. From equation (1), we have;

L = $1,300 - S

Similarly, from equation (2),we have;

C = ($1,400 - S)/2

Substituting the values of L and C in equation (3), we have;

S + $1,300 - S + ($1,400 - S)/2 = $1,600

Which gives;

($1,400 - S)/2 = $1,600 - $1,300 = $300

$1,400 - S = 2 × $300 = $600

$1,400  = $600 + S

$600 + S = $1,400

S = $1,400 - $600 = $800

S = $800

The cost of a love seat, L, is given from the relation L = $1,300 - S, above, which gives;

L = $1,300 - $800 = $500

The cost of a love sea, L is $500 .

Step-by-step explanation:

Answer: D, 161.16 square centimeters.

Step-by-step explanation:

The surface area of a cylinder (shape of each steel rod) is given by this formula:

[tex]A = 2\pi rh + 2\pi r^2[/tex], where the first 2*pi*r*h measures the area of the curved surface while the second 2*pi*r^2 measures the area of the two circles on the top and bottom.

We are given the area of the top of one rod, which is 7.07 square centimeters.

We are also given the area of the body of one rod, which is 39.58 square centimeters.

The top of one rod is the shape of a circle, and we know there are two circles on both sides of a cylinder, so the surface area of both circular sides are 7.07.

The total surface area of a cylinder is the body plus both circular ends, so the surface area for this cylinder is:

39.58 + 7.07 + 7.07 = 53.72

There are three cylinders, so multiply this value by three to get the answer, 161.16 square centimeters.

Answer:

15 miles in one hour

Step-by-step explanation:

Since we know that we need twelve 1/12 hours to make one full hour, we can multiply.

5/4 * 12

5/4 * 12/1

60/4

15

Best of Luck!

Answer: 15 miles

If he can already run 5/4 miles in 1/12 of an hour, we multiply.

First, let's simplify 5/4 to make it easier.

5/4 = 1 1/4.

Alex ran 1 1/4 miles in 1/12 of a hour.

Now, let's multiply 1 1/4 by 12.

1 1/4 x 12 = 15.

Answer = 15 miles. Hope this helps!

We want to find the equation of a line (in slope-intercept form) that passes through (2, -2) and is perpendicular to [tex]y=\frac{2}{5}x+2[/tex].

First, let's find the slope of our new line.

Remember that perpendicular slopes are negative reciprocals of each other.

Therefore, to find the slope of our new line, we will flip our old slope and add a negative.

Therefore, the slope of our new line is -5/2.

Now, we can use the point-slope form:

[tex]y-y_1=m(x-x_1)[/tex]

Where m is the slope and (x₁, y₁) is a point.

So, let's substitute -5/2 for our slope and (2, -2) for our point (x₁, y₁). This yields:

[tex]y-(-2)=-\frac{5}{2}(x-2)[/tex]

Simplify:

[tex]y+2=-\frac{5}{2}(x-2)[/tex]

Let's convert this to slope-intercept form. Distribute the right:

[tex]y+2=-\frac{5}{2}x+5[/tex]

Subtract 2 from both sides. So, our equation is:

[tex]y=-\frac{5}{2}x+3[/tex]

Our answer is D.

We know that the cost for buying x items is given by the function:

[tex]C(x)=6x[/tex]

We also know that the items are sold in packages of 10 only. And no one can buy more than 5 packages. In other words, we can buy 0, 1, 2, 3, 4, or 5 packages.

So, let's see how much it will be if we buy 0 packages. This will just be:

[tex]C(0)=6(0)=\$0[/tex]

If we buy 1 package, there will be 10 items in them. So:

[tex]C(10)=6(10)=\$60[/tex]

If we do this for 2 packages (20 items), 3 packages (30 items), and so on, we will get:

[tex]C(20)=6(20)=\$120\\C(30)=6(30)=\$180\\C(40)=6(40)=\$240\\C(50)=6(50)=\$300[/tex]

So, our range is:

[tex]\{0, 60, 120, 180, 240, 300\}[/tex]

The correct answer is D.

And we're done!
