Answer:
28 is 10% of 280
Steps to solve "28 is 10 percent of what number?"
We have, 10% × x = 28
or,
10
100
× x = 28
Multiplying both sides by 100 and dividing both sides by 10,
we have x = 28 ×
100
10
x = 280
If you are using a calculator, simply enter 28×100÷10, which will give you the answer.
It depends. Generally no.
Linear equations are generally in the form [math]y=mx+b[/math] and have a domain of [math](-\infty,\infty)[/math], or all real numbers. However, an arithmetic sequence is only defines for the natural numbers (that is, while numbers [math]> 0[/math].
For any two terms in the arithmetic sequence, [math]a_n[/math] and [math]a_{n+1}[/math], there will always be a point on the linear function that lies in between them, and is such not defined in the sequence.
This does not make the sequence and function unrelated, but rather it makes them not the same.
A similar argument applies for geometric sequences and exponential equations.
You have to do Rise over Run.
1.) Start at the origin
2.) go down to one of your points, (in this case the point in the 4th quadrant)
3.) Go down 6 units, then 3 units right
4.) The slope is 6/3 or 2/1
m=2/1
The surface are of the right cone is 176 sq.units. Option A) is the correct answer.
<u>Step-by-step explanation</u>:
<u>step 1</u> :
Radius of the cone, <em>r = 4</em>
Height or length of the cone,<em> h = 10</em>
<u>step 2</u> :
Total surface area of right cone = πrh + πr^2
= (π
410) + ( π4^2)
= 40π + 16π
= 56 π = 563.14
= 176 sq.units
