If he paints 1/2 of the wall blue, hoy many square feet will be blue?

Katen [24]

To determine how much of the wall is blue we first need to find its area. The wall is a rectangle, then its area is the product of its height and length:

$\begin{gathered} A=(8\frac{2}{5})(16\frac{2}{3}) \\ A=(\frac{42}{5})(\frac{50}{3}) \\ A=(14)(10) \\ A=140 \end{gathered}$

Hence, the area of the wall is 140 square ft. To determine how much of the wall is already painted we multiply this by 1/2, then:

$(140)(\frac{1}{2})=70$

Therefore, 70 square ft are blue.

A) what is the slope of the parallel to y=2x+3

tekilochka [14]

Answer:

a) 2 b) -1/2

Step-by-step explanation:

a) im pretty sure the question only asks for the slope of the parallel line y=2x+3, that that would be 2 because they have the same slope

b) the question is phrased weird, but im assuming it wants the same thing from a, (the slope) and the slope of a perpendicular like is always the opposite reciprocal of the original number

for example in y=2x+3:

2 is the original slope

meaning that the perpendicular would be -1/2
