Pythagorean Theorem: A^2 + B^2 = C^2
<span>We know A and C, let's find B by doing it backwards </span>
<span>C^2 - A^2 = B^2 </span>
<span>4^2 - 7 (square root of 7 squared is just 7) = B^2 </span>
<span>16 - 7 = B^2 </span>
<span>9 = B^2 </span>

= 1/1 = 1. The answer is 1/1 instead of 1.
Step-by-step explanation:
Answer:
It will take 1.5 hours to paint the room together
Step-by-step explanation:
Martha can paint a room in 2 hours. Jamie can paint the same room in 6 hours.
Work done by Martha in 1 hour =
Work done by Jamie in 1 hour =
Work one together in 1 hour =
Now take common denominator to add both fractions
LCD = 6, Multiply the first fraction by 3
Now add the numerators
To find total hours of painting together, we take reciprocal of 2/3
Time taken to paint together =
It will take 1.5 hours to paint the room together
7x-4x=10-1
3x=9
3/3x=9/3
x=3

Answer: $1.26 </h3>
=======================================================
Work Shown:
2.25% = 2.25/100 = 0.0225
2.25% of 56 dollars = 0.0225*56 = 1.26
The amount of sales tax is $1.26
Side note: The total bill is 56 + 1.26 = 57.26 dollars.
