Answer:
C
10% = (10÷100=1÷10)=2÷20=.10
Note: I'm not going to type in case sensitive or correct grammer so it's not my fault if you paste my answer and the program says it's wrong
y=mx+b
m=slope
b=y intercept
the x intercept is where the line crosses the x axis or where y=0
the y intercept is where the line crosses the y axis or where x=0
so
for the slope, solve for y
Ax+By=C
minus Ax both sides
By=-Ax+c
divide both sides by B
the slope is
and the y intercept is at
find x intercept
set y=0
Ax+By=C
Ax+B(0)=C
Ax=C
divide both sides by A
the x intercept is at
or the point
slope is
the x intercept is at
or the point
the y intercept is at
or the point
in short, 25% is just 1/4 of anything, we know she's sold 25% which is $600, so her daily goal must be 1/4 + 1/4 + 1/4 + 1/4, or namely 600 + 600 + 600 + 600 = 2400.
Answer:
C) 550 feet squared
Step-by-step explanation:
Imagine how the surface area of the given figure differs from the surface area of a prism 10 ft by 15 ft by 5 ft without the cutout in the top center. The three 5×5 ft squares that would need to be added to make the prism are of exactly the same area as the three 5×5 ft squares that are the sides and bottom of the cutout.
That is, the area is no different from the area of a 10 ft by 15 ft by 5 ft rectangular prism. That area is ...
A = 2(LW +WH +LH) = 2(10·15 +15·5 + 10·5) ft² = 550 ft²
