Answer:
3 hours
Step-by-step explanation:
You find the LCM between 20 and 15, which is 5. This means that Kim and Tom are both biking at 5 miles per hour, meaning that to determine how much time Tom takes, you would do 15/5, which is 3 hours.

⇒the number raises with 1 each time
b) We see that, from left to right, the number raises each time with 10
754.21 764.321 774.321 784.321 794.321 804.321
c) We see that, from left to right, the number raises each time with 100
125.876 225.876 325.876 425.876 525.876 625.876
If a chord is perpendicular to a segment drawn from the center of the circle, the intersection of the line segment to the chord bisects the chord. In other words, their point of intersection is the midpoint of the chord.
Answer:
<h2>
64/27</h2>
Step-by-step explanation:
If x and y be real numbers satisfying 2/x=y/3=x/y, then any two of the equation are equated as shown;
2/x = y/3 ... 1 and;
y/3 = x/y... 2
From equation 1, 2y = 3x ... 3
and from equation 2; y² = 3x ... 4
Equating the left hand side of equation 3 and 4 since their right hand sides are equal, we will have;
2y = y²
2 = y
y = 2
Substituting y = 2 into equation 3 to get the value of x;
2y = 3x
2(2) = 3x
4 = 3x
x = 4/3
The value of x³ will be expressed as (4/3)³ = 4*4*4/3*3*3 = 64/27
So the equation you would make is 63 / 9 = width
This is because the formula of finding the area of a rectangle is <em>l </em>x <em>w = a</em>.
So since we already know the length and area, we just plug them in and switch up the formula to find the width.
If 9 (length) x ? (width) = 63 (area), then 63 / 9 = ? (width)
If you calculate it in your mind or even a calculator, you will find that 63 / 9 = 7.
Therefore the width of the rectangle is 7.
