Answer:
160
80
40
20
Step-by-step explanation:
You start with the first term that is given which would be
b(1)=<u><em>160</em></u>
That would be our first term, then we multiply by 0.5 which would be 1/2
which gives us 80 as it is a division
You take the next term that we have found (80) and then we do the same thing, multiply by 0.5 (1/2)
Answer:
3/16
Step-by-step explanation:
2^-4 = 1/2^4 = 1/16
Answer:
x = -11/2
Step-by-step explanation:
The ratios need to stay the same
5x 11
----- = -------
x-2 3
Using cross products
5x*3 = (x-2) 11
15x = 11x - 22
Subtract 11 from each side
15x-11x = -22
4x = -22
x = -22/4
x = -11/2

math: 68/85 * 100 = 80%
science: 70*0.9 = 63 number correct
b. Science
c.48
The radius is 10, so the diameter is 20. This means the parts of the diameter (the chord through the center P) to the left and right of the vertical chord have lengths 16 and 4, respectively.
Because the horizontal chord is a diameter, the vertical chord is cut in half, so its parts above and below the diameter both have length <em>x</em>.
Now, by the intersecting chord theorem,
16×4 = <em>x</em> × <em>x</em>
or
<em>x</em> ² = 64
so that
<em>x</em> = 8
