Problem 1
Plot 3 or 4 of the given points. For example, plot (4,16) and one other point given in the table. Draw a straight line through your points. Look carefully: Where does your line cross the y-axis? If y = 14 (just an example, not the correct value), then the y-intercept is (0,14).
To find the slope of your line, choose any 2 of the given 4 points. Find the slope of the line segment connecting those 2 points. For example:
24 - 16 8
m = ------------- = -------- = 2. The slope of this line is m=2.
8 - 4 4
Now you have both the slope (2) and the y-intercept (b). The equation of this line is thus
y = 2x + b (you found b earlier).
Answer:
I'm sorry but where's the picture
Answer:
3240 in^3
Step-by-step explanation:
Step one:
given data
The dimension of the form
Length 40 and 1/2 inches long,
Depth 10 inches deep,
The width and 8 inches high
Step two:
The amount of cement is equivalent to the volume of the form
Hence the volume of cement is 3240 in^3
The answer is 1.85
To figure this out, think about what we want. We want our original number plus 85% of the original number. The 1 part will give you back your original number, and the 0.85 part will add 85%.
