Answer:
$20,800
Step-by-step explanation:
1st
multiple the amount he makes an hour by the hours he works
10×40 = 400
2nd
there is 52 weeks in a year
so multiple the total he earns by 52
400×52=20,800

Here's how to convert 0.00064 to a fraction...
<span>There is not much that can be done to figure out how to write 0.00064 as a fraction, except to literally use what the decimal portion of your number, the <span>.00064 </span>, means.Since there are 6 digits in 00064 , the very last digit is the "1000000th" decimal place.So we can just say that .00064 is the same as 00064 /1000000.<span>The fraction is not reduced to lowest terms. We can reduce this fraction to lowest
terms by dividing both the numerator and denominator by 64.
</span><span>Why divide by 64? 64 is the Greatest Common Divisor (GCD)
or Greatest Common Factor (GCF) of the numbers 64 and 1e+06.
So, this fraction reduced to lowest terms is</span><span>So your final answer is: 0.00064 can be written as the fraction</span></span>
Answer:
iii) Use algebraic methods
Step-by-step explanation:
There are various method of finding an accurate solution to a system of linear equations.
They are i) graphing method: ii) algebraic method: iii) Matrices method:
iv) determinant method: v) guess method vi) Cramer's rule etc
Guess and check is not reliable because guess is possible only for integers or numbers with 1 or 2 decimals. SOmetimes guess may give unreliable results. And every time after the guess, checking and verifying will be time consuming and laborious
Graphing the lines may be accurate but writing tables for each line, choosing scales and drawing lines to find points of intersection may be time consuming.
Algebraic methods using are easy to understand, reliable, and less time consuming but 100% accuracy. There are a number of ways in algebraic method also such as substitution, elimination or cross multiplication, etc
Thus option iii) is right
3x-6 = 2x+14
x=20
Assuming the triangle is equal all three sides
