Since it was stated that the equation is linear, therefore
we can use the slope point formula to find for the slope and intercepts. The
linear equation has a form of:
y = mx + b
where y is the retail price, x the wholesale price, m the
slope and b the y-intercept
m = (y2 – y1) / (x2 – x1)
m = (238 – 112) / (175 – 85)
m = 1.4
So the equation now becomes:
y = 1.4x + b
Plugging in any pair to find for b:
112 = 1.4(85) + b
b = -7
So the full equation is:
<span>y = 1.4x - 7</span>
<span>or</span>
<span>R = 1.4C - 7</span>
Answer:
2141.76 cubic inches
Step-by-step explanation:
Given that it measures 8.8 inches across a properly inflated basketball i.e. the diameter of each basketball is 8.8 inches.
So, the radius of the spherical ball is inches.
Now, a spherical solid has a volume given by .
Hence, volume of air in side each basketball is = cubic inches.
Therefore, the total volume of air inside six balls will be = 6 × 356.96 = 2141.76 cubic inches. (Answer)
Simplify what? I dont see anything sorry
Answer:
The area of the shaded region is 5.86\ cm^{2}
Step-by-step explanation:
The area of the shaded region is equal to the area of the rectangle minus the area of the circle
The rectangle is a square
so
A=b^{2} -\pi r^{2}
we have
b=3\ cm
r=1\ cm
assume
\pi =3.14
substitute the values
A=3^{2} -(3.14)(1)^{2}
A=5.86\ cm^{2}
Work and answer shown above! Hoped this helped.
