<span>I get 0.26% for part A and 75% for part B. My work is in the attached document.</span>
Answer:
The area of the triangle should be: [(1 + 5 + 4) × 11]/2= 55 (ft²)
The area of the rectangle should be: 5 × 2 = 10 (ft²)
The area of the shaded region is: 55 - 10 = 45 (ft²)
To obtain an equivalent fraction by multiplying, multiply the whole fraction by any single number. Example: 3/4 multiplied by 3 is 9/12. Those fractions are equivalent.
To obtain an equivalent fraction by dividing, look at the top number and the bottom number. If they both can be divided by a number without it being a decimal, it’s an equivalent fraction. Example: 8/10, both of those numbers can be divided by 2 that isn’t a decimal, 4/5. 4/5 and 8/10 are equivalent
The answer is choice 1 because when you divide 2 numbers with the same base and different exponents you subtract the second exponent from the first.
p^-m / p^-n = p^(-m - (-n))
CHOICE 1
Hope this helps
Steve did it perfectly, because he got the common denominator first, then expanded and subtracted.
