I looked it up, it says eq triangles have 3 sides. An isos triangle is one with 2 equal sides. Every eq triangle is isos, but not every isos triangle is equilateral. I think the statement in the photo is true.
2*2*3*5 are the prime factors of 60
Answer:
the actual sales be $31,132
Step-by-step explanation:
The computation of the actual sales is as follows:
Let us suppose the actual sales be x
Now the sales tax be 0.06x
Now the total sales would be
x + 0.06x = $33,000
1.06x = $33,000
x = $33,000 ÷ 1.06
= $31,132
hence, the actual sales be $31,132
The same is to be considered by applying the above equation
10000 different phone numbers are possible for a particular prefix if repetion of digits is allowed
5040 different phone numbers are possible for a particular prefix if repetion of digits is not allowed
<em><u>Solution:</u></em>
Given that,
A seven digit phone number consists of a three-digit prefix followed by four digits
We have to find the different phone numbers are possible for a particular prefix
For a paricualr prefix, there are four digits
Total numbers from 0 to 9 are 10
Therefore,
Different ways for phone number for particular prefix:
If repetition is allowed:
Different ways = 10 x 10 x 10 x 10 = 10000 ways
If repetition is not allowed then:
Different ways = 10 x 9 x 8 x 7 = 5040 ways
The meaning of the question is
Let the unknown number be x
Therefore x+7=16-2x
Now 2x+x=16-7
3x=9
X=9/3
x=3
