I did know is understandable is the web in math?
Answer:
400 ft
Step-by-step explanation:
The building's shadow is 10 times the length of the flagpole's shadow. Since the shadow length is proportional to the object height, the building must be 10 times the height of the flagpole, so is 400 ft tall.
Answer:
Slope: 1/2.5
Y-intercept: -1
Step-by-step explanation:
Question is asking about which shows the equation 
in general form. Options are not given but we can still find the solution.
Given equation is a linear equation so we will need to check general formula of the equation of line. which is given by formula:
Where a, b and c are integers.
Now compare given equation with general formula to find the difference between them.
We see that every term is on the left side of the = in formula but 480 is on the right side of give equation so we will move 480 to the left side.
to do that we subtract 480 from both sides
Now the new equation looks exactly like the general formula.
Hence final answer is
y = 19
x = 4(19) + 21(19) = 76 + 399 = 475
3(475) × 7
1425 × 7
9975 <--- answer.
Hope this helped!
