After 45 minutes you will have painted 4*45=180 square feet.
so the total number of painted area, y, is:
y=180+x*(3+4) after the 45 minutes
where x is the number of minutes AFTER THE 45 minutes:
if y is 1000 then
1000=180+x*7
820=x*7
x=117.14
so 117 minutes, or one hour and 57 minutes.

Answer:

Step-by-step explanation:
The equation in slope-intercept form is given by:

where
is the slope and
is the y-intercept.
The given line passes through so many points. We can use any two these points to find the slope of the line.
The line passes through
and
.
The slope is given by;
.
.
.
The y-intercept from the graph is 
Our equation finally becomes;

Answer:
102.40 ft
Step-by-step explanation:
This system can be described as a right triangle with the horizontal distance from the silo (80 ft) being the side adjacent to the 52-degree angle, and the height of the silo (h) being the side opposite to the angle. Therefore, the height can be found by:

The silo is 102.40 feet tall.
