C. -14x
Just multiply 3 with -5 and get -14x. And then add a positive x to get -14x
Answer:
1. The volume of the pile is 4,399.7719 m^3
2. The number of sanders to be filled from a pile is 638
Step-by-step explanation:
Here, we firstly would calculate the volume of the pile
Mathematically, that will be;
V = 1/3 * pi * r^2 * h
from the question, h = 14.2
Mathematically, r = d/2
r = 34.4/2 = 17.2 m
So the volume will be:
V = 1/3 * 3.142 * 17.2^2 * 14.2
V = 4,399.7719 m^3
To find the number of sanders to be filled,
we simply divide the volume obtained by the volume a sander can take
That will be;
4,399.7719/6.9
= 637.6 which is 638
Answer:0.27
Step-by-step explanation:
First, we convert the fraction to a decimal number by dividing the numerator by the denominator:
4 / 15 = 0.266
There are two parts to the decimal number above:
Integer Part: 0
Fractional Part: 266
Now, we will make the Fractional Part just two digits (nearest hundredth) by using our rounding rules.*
In this case, Rule II applies, so 4/15 (or 0.266) rounded to the nearest hundredth in decimal format is:
0.27
Answer:
to find the area of a circle
use the formula
A = πR2
but first we need to find the radius
R= diamater/2
so our redius is 52/2 = 26
so plug in to the formula
A=πR2
A=3.14(26)^2
A =2123.7166338267
