One gallon of paint covers about 450 square feet. How many square feet will 1.5 gallons of paint cover? 300 sqft
900 sq ft
675 sq ft
451.5 sq ft
please answer !!

Option A: 300 square feet.

Step-by-step explanation:

In this question, all you do is divide! What is 450 / 1.5? 300. And don't forget to add your unit.

675 sq ft

Step-by-step explanation:

If one gallon covers 450 sq ft, then 1.5 gallons covers 450 sq ft + 50% of 450.

So...

Divide 450 by 2

450 / 2 =

225

Then Add

450 + 225 =

675 sq ft

option c) graph of line going through 1, 4 and 3, 10

step-by-step explanation:

let y equal to margo's coin collection

let x equal to number of years

at the begining x=0, y=1 → point=(x,y)→point=(0,1)

she adds 3 coins per year, then y=1+3x

at x=1, y=1+3(1)=1+3→y=4→point=(x,y)→point=(1,4)

at x=3, y=1+3(3)=1+9→y=10→point=(x,y)→point=(3,10)

the graph of line going through (1, 4) and (3, 10), then the option c is the correct.

for this case we have by definition, if two lines are perpendicular, then the product of their slopes is -1.

then, given the following line:

so,

we are looking for m_ {2}:

then, the line is given by:

we find "b" replacing the given point:

finally, the equation is:

option c
