The wall is a rectangle, so by the pythagorean theorem, the diagonal squared minus the height squared equals the width squared. This gives a width of 42.80 feet. The area of the wall is width (42.80 ft) x height (8.3 ft), equal to 355.26 square ft. The can covers 21.5 square feet, so John needs 16.52 cans to cover the wall. As he can't buy half a can, John should purchase 17 cans of spraypaint.<span>The wall is a rectangle, so by the pythagorean theorem, the diagonal squared minus the height squared equals the width squared.

Percent means parts out of 100
36% =36/100=0.36
'of' means mulitply
27 is 36% of ? translates to
27=0.36 times ?
divide both sides by 0.36
75=?
the number is 75
Answer:
-23/24
Step-by-step explanation:
get common denominator =24
-8/24 + -15/24
-8 + -15 = -23
keep bottom
-23/24
22 divided by 2 is 11 and 11 plus 3 is 14 so your answer is 14
The length and the width of the outside edge of the garden will be ( 6x + 12 ) and ( 9x + 6 ) respectively.
<h3>What is the scale factor?</h3>
In mathematics, a scale factor is the proportion of related dimensions of an object to a description of that object.
Given that:-
- The outside edges of the walkway form a rectangle whose length and width are proportional to the sides of the garden, increased by a scale factor of 3. the sides of the garden are (2x+4) and (3x+2)
The length and width of the outside edge will be:-
The sides are Dilated by factor 3 so the edges of the rectangle will be calculated as;-
Length = 3 ( 2x+4 ) = 6x + 12
Width = 3 ( 3x+2 ) = 9x + 6
Therefore the length and the width of the outside edge of the garden will be ( 6x + 12 ) and ( 9x + 6 ) respectively.
