His allows you to set up a summation of the form:

Summation from i = 1 to 500 of i.

The general solution to the summation of i from 1 to n is n(n+1)/2. In this case, n = 500.

500(501)/2 = 125250

Recall that you divided the sum by 2 to simplify its computation. Now multiply your result by 2 for your final answer:

125250 * 2 = 250500

3. A piece of white oak has a densityof 0.77 g/cm and a mass of 100 g,what would be the volume of thesample? PLEASE HELP!

Nezavi [6.7K]

$\text{Volume}=129.87cm^3$

Explanation

Step 1

the density of an object is given by:

$\text{density}=\text{ }\frac{mass}{\text{volume}}$

Step 2

let

$\begin{gathered} \text{density}=0.77\frac{g}{cm^3} \\ \text{mass}=\text{ 100 g} \\ \end{gathered}$

Step 3

replace,

$\begin{gathered} \text{density}=\text{ }\frac{mass}{\text{volume}} \\ 0.77\frac{g}{cm^3}=\frac{100g}{\text{volume}} \\ \text{volume}\cdot0.77\frac{g}{cm^3}=\text{1}00\text{ g} \\ \\ \text{Volume}=\frac{100\text{ g}}{0.77\frac{g}{cm^3}} \\ \text{Volume}=129.87cm^3 \end{gathered}$

I hope this helps you

The following three shapes are based only on squares, semicircles, and quarter circles. Find the perimeter and the area of each

MakcuM [25]

The perimeter = 4 * length of a semicircle of radius 5 == 4* pi * 5 = 20 pi cm

The area of one of the clear parts = 1/2 area of square - area semicircle

= 1/2 * 10^2 - 1/2 pi *5^2 = 50 - 12.5pi

So area of shaded parts = area of square - 4 (50 - 12.5pi)
= 100 - 200 + 100pi = (100pi - 100) cm^2
