Answer:

You could use the polygon area formula OR here's an easier solution

We draw the lines DC and DE

Angle ADC = 120°

Triangle ADC is a 30 60 90 triangle

In such a triangle Line AE = hypotenuse * sq root (3) /2

Line AE = 3 * 0.8660254038 = 2.5980762114

Line DE = 1.5

Area of Triangle ADE = .5 * 1.5 * 2.5980762114 =

1.9485571586 square meters and entire area of Triangle

ABC = 6 * 1.9485571586

which equals 11.6913429513 square meters

Two students are reading a novel. Ashley reads 10 pages per day. Carly reads 8 pages per day, but she starts early and is alread

BARSIC [14]

Answer:

The word per indicates the slope (m) of a linear function, y=mx +b.Using d for x and p for y , the equation representing Ashely's reading is p = 10d. Carly begins on page 40 which represents b, the y intercept of a linear function which indicates an initial amount. So the equation representing Carly's reading is p=8d + 40.

A company wants to manufacture rolls of toilet paper. The toilet paper roll is in the shape of a hollow cylinder with a diameter

serg [7]

Answer:

$ 40.6 to make the 50 rolls of toilet paper

Step-by-step explanation:

We have that the diameter of every cylinder is 4.75 inches, therefore the gap would be that value minus the thickness of the paper, like this:

4.75 - 1.7 = 3.05

3.05 inches would be the diameter of the hole.

Now, to know the volume of the paper, we would have to calculate the total volume and then subtract the volume of the hole.

First we calculate the radii:

r = d / 2

r1 = 4.75 / 2

r1 = 2.375 in

r2 = 3.05 / 2

r2 = 1.525 in

Now if we calculate the volumes

Total volume:

Vt = pi * (r ^ 2) * h

Vt = 3.14 * (2,375 ^ 2) * 3.9

Vt = 69.08 in ^ 3

Hollow volume

Vh = 3.14 * (1,525 ^ 2) * 3.9

Vh = 28.48 in ^ 3

We subtract:

Vt - Vh = 69.08- 28.48 = 40.6

40.6 in ^ 3 would be the volume of the toilet paper

We need to know what it costs to create 50, we know it costs $ 0.02 per cubic inch

Then it would be:

40.6 * 0.02 = 0.812

In other words, making one costs $ 0.812, so making 50 would cost:

0.812 * 50 = 40.6

In other words, it costs $ 40.6 to make the 50 rolls of toilet paper
