Answer: 16.1 ounces per minute
Step-by-step explanation:
in 7 days, he painted by 4 hours each day, so we have a total of 28 hours.
In a hour we have 60 minutes, so we have a total of:
28*60 = 1680 minutes.
He used 211 gallons, and knowing that 1 gallon is 128 ounces, then 211 gallons is:
211*128 ounces = 27,008 ounces.
Then the ounces dispensed each minute are:
R = 27,008/1680 ounces per minute = 16.1 ounces per minute

Answer:
y = 2x-4
Step-by-step explanation:
x + 2y = 2
The slope intercept form is
y = mx+b where m is the slope and b is the y intercept
First find the slope of the line
2y = -x+2
Divide by 2
y = -1/2x +1
The slope of this line is -1/2
We want a line that is perpendicular, which is the negative reciprocal
-1 /(-1/2) = 2
The slope intercept form is
y = mx+b where m is the slope and b is the y intercept
y = 2x+b
Substitute the point into the line
6 = 2(5)+b
6 = 10+b
6-10 =b
-4=b
y = 2x-4
Considering the area of the rectangle, we have that the length is of 8 units and the width is of 10 units.
<h3>What is the area of a rectangle?</h3>
The area of a rectangle of length l and width w is given as follows:
A = lw.
In this problem, the area is of 80 square units, while the length and the width are consecutive even integers, hence:
Then:
l(l + 2) = 80
l² + 2l - 80 = 0
(l + 10)(l - 8) = 0.
We need the positive measure, hence:
l - 8= 0 -> l = 8 units.
w = l + 2 = 10 units.
