7 0

<span>A word problem that can be modeled by addition of two negative numbers integers is given as followed.

Evans and Irvin are standing at the same spot. Evans took 7 steps backwards and another 7 steps backward, what is the current position of Evans relative to where Irvin is standing?

To solve the above, we note that Evans </span><span>took 7 steps backwards and another 7 steps backward, thus his current position relative to Irvin is given by (-7) + (-7) = -7 - 7 = -14.

Therefore, Evans is 14 steps backwards relative to where Irvin is standing.

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,

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

Greatest percent

cricket20 [7]

Answer:

Percent change from 15 to 18.

You need to divide the numbers, but which one goes on top?

You know the number increases from 15 to 18, so the percentage must be greater than 100%.

The only way to get a number greater than 100% is to put the larger number on top.

Therefore, the answer is 18/15 = 1.2

Multiply by 100 to get a %

1.2 * 100 = 120%

2. Calculate percentage change

from V1 = 5 to V2 = 8

ans= 60%

overall answer gain of 15 yards and 18 yards

I believe you just multiply all the values together

3 x 3 x 9 = 81

You can make 81 different pizzas
