A box of pencils is 5 1/4 inches wide. Seven pencils, laid side by side, take up 2 5/8 inches of the width. How many inches of t

Andre45 [30]

Answer: Width of box is not taken up by pencils = $2\dfrac58\text{ inches}$

Width of each pencil $=\dfrac38\text{ inches}$

Step-by-step explanation:

Given: Width of pencil box = $5\dfrac14\text{ inches}=\dfrac{21}{4}\text{ inches}$

Width of seven pencils = $2\dfrac58\text{ inches}=\dfrac{16+5}{8}\text{ inches}=\dfrac{21}{8}\text{ inches}$

Width of box is not taken up by pencils = Width of pencil box - Width of seven pencils

$\left \{ {{y=2} \atop {x=2}} \right. \dfrac{21}{4}-\dfrac{21}{8}\\\\=\dfrac{21\times2-21}{8}\\\\=\dfrac{21}{8}\text{ inches}=2\dfrac58\text{ inches}$

Width of box is not taken up by pencils = $2\dfrac58\text{ inches}$

Width of each pencil = (Width of seven pencils ) ÷ 7

$=\dfrac{21}{8}\div7\\\\=\dfrac{21}{8}\times\dfrac17\\\\=\dfrac38\text{ inches}$

Width of each pencil $=\dfrac38\text{ inches}$

-50 Points-<br> Find the area of the smaller sector.<br> Leave your answer in terms of pi.

quester [9]

The formula to find the area of a sector is:

A = $\frac{degree}{360} \pi r^{2}$

In this case:

Degree = 40

Radius = 8

^^^Plug these numbers into the formula given above

A = $\frac{40}{360} \pi 8^{2}$

Solve

A = $\frac{1}{9}$ π8²

A = $\frac{1}{9}$ π64

A = $\frac{64}{9}\pi$

A = 7.1111111π

When rounded:

7.1π is the area of the sector

Hope this helped!

On the first day of winter, an entire field of trees starts losing its flowers. The number of locusts remaining alive in this po

Temka [501]

Answer:

Every day, there is a 49% percent the locust population.

Step-by-step explanation:

To find the daily percent change of the locust population, we just need to find N(t) for t = 0, N(t) for t = 1, then subtract the second by the first, and then divide the result by the first:

N(t) = 8950*(0.7)^2t

N(0) = 8950*(0.7)^0 = 8950*1 = 8950

N(1) = 8950*(0.7)^2 = 8950*0.49 = 4385.5

Change = N(1) - N(0) = 4564.5

Percent change = Change/N(0) = 4564.5/8950 = 0.51 = 51%

As after one day, the population decrease by 51% of the inicial population, the remaining population is 100% - 51% = 49%, so we can write:

Every day, there is a 49% percent of the locust population.

The population of a certain bacteria doubles in size every 3 hours. If a population begins with one bacterium, how many will the

gladu [14]

There would be 256 bacteria after one day.

There are 24 hours in a day, and the amount of bacteria doubles every 3 hours, so it will double:

24 / 3 = 8 times.

To find the current amount we could use an equation such as:

1 * 2^8 = x

Finally, solve for the number of bacteria:

1 * 2^8 = x

1 * (2 * 2 * 2 * 2 * 2 * 2 * 2 * 2) = x

1 * (4 * 4 * 4 * 4) = x

1 * (16 * 16) = x

1 * 256 = x

x = 256
