3. You have decided to wallpaper your rectangular bedroom. The dimensions are 12 feet 6 inches by 10 feet 6 inches by 8 feet 0 i

Shalnov [3]

Answer:

B. 5 rolls

Step-by-step explanation:

The areas of the room, not including the ceiling, are discriminated as follows:

Longer walls: $(12.5\times8)\times2=200ft^2$ (6 inches equals one foot)

Shorter walls: $(10.5\times8)\times2 = 168ft ^ 2$ (6 inches equals one foot)

Window area: $(4\times3)\times2 = 24ft ^ 2$

Door area: $(7\times3) = 21ft ^ 2$

Area that will be effectively covered:

Total area to wallpaper: $200 + 168 -24 -21 = 323ft ^ 2$

Amount of paper needed: $323\times1.1 = 355.3ft ^ 2$

$30in = 24in + 6in = 2ft + 0.5ft = 2.5ft.$ That is, the area of a roll of paper is $2.5\times30 = 75ft ^ 2$

Number of rolls needed:

$\frac{355.3}{75} = 4.73$ rolls

Write an inequality to represent the graph. a dashed line passing through points 0 comma negative 3 and 2 comma 2 with shading a

scZoUnD [109]

Answer: y > (5/2)*x - 3

Step-by-step explanation:

Ok, the thins we should notice.

The line is shaded, so the values of the line are not solutions of the inequality, then we should use < or >.

The shaded part is above the line, so we have:

y > a*x + b.

A linear relationship can be written as:

f(x) = a*x + b

where a is the slope and b is the y-axis intercept.

For a line that passes through the points (x1, y1) and (x2, y2), the slope can be written as:

a = (y2 - y1)/(x2 - x1).

Now, we know that our line passes through the points (0, -3) and (2, 2)

Then the slope is:

a = (2 -(-3))/(2 - 0) = 5/2.

f(x) = (5/2)*x + b.

To find the value of b, we can replace the values of one of the points in the equation, let's use the point (0, -3)

f(0) = -3 = (5/2)*0 + b

-3 = b

Then the line is:

f(x) = (5/2)*x - 3

Then the inequality is:

y > (5/2)*x - 3

A survey determined that 5/18 of the seventh grade students at Mills Middle School preferred round chocolate candies to hard can

Fudgin [204]

Answer:

The correct answer is B) 1/9

Step-by-step explanation:

In order to find this answer, you need to take the fraction that answered it on the first try and subtract the number that changed their mind.

5/18 - 1/6

In order to complete this operation, you need to give them common denominators.

5/18 - 3/18 = 2/18

And we can simplify that answer.

2/18 = 1/9
