9
Step-by-step explanation:
Answer:
Length = 55 ft
Step-by-step explanation:
Given:
Area of rectangular floor= 605ft²
Length= x
Width= 1/5x
Formula for area of rectangular floor= Length × width
Put the given into the formula.
605 ft² = x × 1/5x
605 ft² = x²/5
multiplying both sides by 5
605 ft² × 5 = x²/5 × 5
x² = 605 ft² × 5
= 3025 ft²
x= √3025 ft²
x= 55 ft
Put x into the unknown above.
Length= x
Width= 1/5x
Length = 55 ft
Width= (1/5)×55 = 11 ft
Simplify the equation
√363 becomes 11 √3
3 √27 becomes 9 √3
11 √3 - 9 √3 = 2 √3
Explanation: Find the factors of each number
363 factors are 33, and 11
Find which one you can take the square root from which is 33 and that is how you get 11 √3
3 √27 can be simplified more because the factors of 27 are 9, 3 take the square root of 9. And multiply the leftover 3 with the outside number which is also 3. Then you get 9 √3
Now just subtract
11 √3 - 9 √3
= 2 √3
Sorry if this is confusing but I hope it helps !!
Change the Whole Number to a fraction, or just plug it in a claculator 7-(4/24)= 6.8333333333.
if you change the whole number to a fraction you would have to multiply 7 by 24 to have a common denominator which would give you 168/24 so
