Answer:
168 in², 94.25 yd²
Step-by-step explanation:
I couldn't find a formula for the SA of a triangular prism so I just found the area of each surface.
The formula for SA of a cylinder is 
All work for triangular prism is in the image
F(x)=125-(125*0.2x)
to find the value of the phone after 3 years, you put x=3.
f(3)=125-(125*0.2(3))
f(3)=50
Answer:
y = x + 3
Step-by-step explanation:
Slope-intercept form is represented by the formula
. We can write an equation in point-slope form first, then convert it to that form.
1) First, find the slope of the line. Use the slope formula
and substitute the x and y values of the given points into it. Then, simplify to find the slope, or
:
Thus, the slope of the line must be 1.
2) Now, since we know a point the line intersects and its slope, use the point-slope formula
and substitute values for
,
, and
. From there, we can convert the equation into slope-intercept form.
Since
represents the slope, substitute 1 in its place. Since
and
represent the x and y values of a point the line intersects, choose any one of the given points (either one is fine) and substitute its x and y values into the equation, too. (I chose (0,3).) Finally, isolate y to find the answer:

28% is 28/100 as a fraction but the simplest form is 14/50 and it can be simplified to 7/25. the decimal is 0.28
fraction is 7/25
decimal is 0.28
98 divided by 7
98/7 = 14
