Problem
8 over 3
g over 3
Cross multiply
8 × 3 = 24
g × 3 = 3g
__________
24 × 3g
--- ----
3 3
(Cross out "3g" and "3" on the right )
Then "divide" 24 and 3. It should leave you with 8
Your answer: g= 8
2 Letters chosen among 6 with no repeat:
a) the first has 6 ways
the second has 5 ways
Then to choose 2 letters among 6, with no repeat, there are 6x5 = 30 ways
b) 3 numbers are taken from the digits 0 through 9 with repeats (total = 10)
the first has 10 ways
the second has 10 ways
the third has 10 ways
Then to choose 3 numbers among 10, with repeat, there are 10x10x10= 1000 ways
And the total serial numbers that can be generated is
30 x 1000 = 3000
Answer:
32
Step-by-step explanation:
Answer:
3/12 or 1/4
Step-by-step explanation:
To find what is between, we have to use the formula:
x + y= z
z/2 = midpoint!
So, we can do that with this number.
1/6 + 2/6 = 3/6. We could simplify it, but let’s keep it at 3/6
3/6 divided by 2 = 3/6 · 1/2 = 3/12
So, the midpoint would be 3/12.
Answer: 72
Step-by-step explanation:
L= 3W
area of a rectangle A= LxW
replace L with 3 W
A=3W*W= 3w^2
243=3W^2
243/3=W^2
81=w^2, and W=9
L=3*9=27
P= (L+W)=2(27+9)=72
