Explanation:
____________________________
Method 1)
____________________________
(4/5) *(20/1) = ?
The "5" cancels to a "1" ; and the "20" cancels to a "4" ;
(since "20÷5=4" ; and "5÷5=1") ;
________________________________
Rewrite as: (4/1) * (4/1) = 4 * 4 = 16.
_________________________________
Method 2)
_______________________________
4/5 * 20/1 = (4*20)/(5*1) = (80/5) = 16 .
_________________________________
Method 3)
_________________________________
4/5 * 20 = ? ;
4/5 = 8/10 = 0.8 ;
0.8 * 20 = 16.0 = 16.

Answer:
<h3>y - 3 = 2(x+1)</h3>
Step-by-step explanation:
The equation of the line in point slope form is expressed as;
y - y0 = m(x-x0)
m is the slope
(x0, y0) is a point on the line
Get the slope;
Given the points (-1,3) and (1, 7)
m = y2-y1/x2-x1
m = 7-3/1+1
m = 4/2
m = 2
Substitute the point m = 2 and the point (-1, 3) into the formula above as shown;
y - y0 = m(x-x0)
y - 3 = 2(x-(-1))
y - 3 = 2(x+1)
Hence the required equation is y - 3 = 2(x+1)

Answer:
The diameter is twice that, or approx. 7.90 units.
Step-by-step explanation:
the equation for the volume of a cylinder of radius r and height h is
V = πr²h. Here we need to calculate the diameter after having found the radius. Solving V = πr²h for r², we get:
V
r² = -----------
πh
Substituting the given values, we obtain for r² the following:
145 units³
r² = ------------------------ = 15.6 units²
3.14159(5 units)
Taking the square root of both sides, we get:
r = √15.60, or approx. 3.95 units.
The diameter is twice that, or approx. 7.90 units.
30inc=76.2cm
76.2*pi=76.2pi
1cm=0.0328084 foot
1 mile=<span>5280 ft
</span>5280/0.0328084=160934.4
1 mile=160934.4 cm
160934.4 /76.2pi=672.27
672 revolutions i think
