Answer:

27 units^2

Step-by-step explanation:

The total surface area is calculated by adding all the areas on the surface: the areas of the base, top, and lateral surfaces (sides) of the object. This is done using different area formulas and measured in square units. Volume is the amount of space that a three dimensional object takes up.

So you add, next time you get another question like this

Please help with 3! i don’t know how to graph it or work it out

seraphim [82]

Answer:

The graph is attached.

Step-by-step explanation:

$\frac{2}{x}$ + $\frac{y}{4}$ = $\frac{3}{2}$

$\frac{y}{4}$ = - $\frac{2}{x}$ + $\frac{3}{2}$

Multiplying both sides by 4 gives;

y = $\frac{-8}{x}$ + 6

You can graph this solution using a graphing calculator to get the answer as attached.

What is the equation of the line that passes through the points (2, –1) and (6, 1)? A.y=1/2x -2 B.y=2x-5 C.y=-1/2x-1 D. y=-2x-3

Rzqust [24]

Answer:

option A.

y = (1/2)x - 2

Step-by-step explanation:

It is given that, line that passes through the points (2, –1) and (6, 1)

Slope m = (y₂ - y₁)/(x₂ - x₁)

= (1 - -1)/(6 - 2)

= (1 + 1)/4 = 2/4

= 1/2

<u>To find the equation of the line</u>

Equation of a line passing through the points (x₁, y₁) and slope m is given by,

(y - y₁)/(x - x) = m

Here (x₁, y₁) = (2, -1) and m = 1/2

(y - -1)/(x - 2) = 1/2

(y + 1) = (x - 2)/2

y = -1 + x/2 - 2/2

= -1 + x/2 - 1

= x/2 - 2

The equation of the line is,

y = (1/2)x - 2

The correct answer is option A.

y = (1/2)x - 2

A large van is being used for a picnic. There will be 8 people riding in the van, and there are 8 seats in the van (one of which

Julli [10]

Answer:

The people can seat themselves in 20160 different ways.

Step-by-step explanation:

Arrangements of n elements:

The number of arrangements of n elements is given by the following formula:

$A_{n} = n!$

In this question:

For the first seat, that is, the driver seat, 4 possible people can sit.

For the remaining 7 seats, the number of ways in which the people can sit is an arrangement of 7 elements. So

$T = 4*7! = 4*5040 = 20160$

The people can seat themselves in 20160 different ways.

vitfil [10]

Answer:

$7.02

Step-by-step explanation:

Price of 92 sheets = 92 * $0.50 = $46

Price of 2 packages = 2 * $19.99 = $38.98

Savings = $46 - $38.98 = $7.02
