Kevin is tiling his bathroom. The floor is 6-by-5 feet, minus a 2-by-2.5-feet vanity. The tiles he likes are 1-by-1 foot. If he plans to buy 10 percent extra for waste, how many tiles will he need?

He plans to buy 28 tiles.

Step-by-step explanation:

Given: Dimensions of floor = 6-by-5 feet

Since area of rectangle = length x width

Then , area of floor = 6 x 5 square feet = 30 square feet

Dimension for vanity  2-by-2.5-feet , area of vanity = 2 x 2.5 sq. feet = 5 sq. feet

Area of floor for tiling = 30 square feet -  5 sq. feet

= 25 square feet

Area of 1 tile = 1 x 1 = 1 square  feet

Number of tiles required to cover 25 sq. feet =  25÷1=25

10 percent extra = 10% of 25+25 = 2.5+25=27.5 ≈28

Hence, he plans to buy 28 tiles.

step-by-step explanation:

i think something is missing in your question because y-1=(x-12) would not pass through the point (-4,-3). because if you replace x by -4 your are supposed to find y=-3 which is not the case her. if you replace x by -4 you find =-15.

i assume the right equation is y-1=1/4*(x-12) because this one is passing through both your points (if you are interested to know how i found that out i can tell you).

in this equation if i replace x by -4 i find y=-3 and if i replace x by 12, i find y=1 so the line representing this equation is passing through those 2 points.

then the standard form of the equation is finding an expression of y in function of x

y-1=1/4*(x-12)

y=x/4-3+1

y=x/4-2

hope that .

do you confirm there was a mistake in the question?

120 seems like the most sensible answer.

step-by-step explanation:

if there is only one topping on all caramel apples and there's 120 of them. then all apples should/will be covered in sprinkles. make sense?
