Answer:
x=75
Step-by-step explanation:
if the polygons are similar
40 30
------- = --------
100 x
using cross products
40x = 30*100
40x =3000
divide by 40
40x/40 = 3000/40
x =75
You have to multiply the 9 by 4 to get see how many beads were used.
9×4=36
The Answer Will Be 1.1205 x 10 To The 5th Power.
The formula C(n, r) calculates the total number of ways of picking r objects out of n.
The formula works as follows:

where n! is 1*2*3*...*(n-1)*n
So, we calculate C(150, 4), which will give us the total number of ways we can make the selection of the computers.


many ways.
Answer: 20,260,275
9.16 times 106=970.96
8.05 times 108=869.4
Next, subtract 970.96 minus 869.4. That equals 101.56.
Then, to put that in scientific notation move the decimal three places to the left. The answer is 1.0156x10^2
