4 is 16.3, I don't know 5 or 6, 7 is 176, I don't know 8 or 9, 10 is 8.1, I don't know 11, and 12 is 48.
(I used a calculator, lol)
Answer:
x = 0, y = 0
Step-by-step explanation:
The numbers are: n, (n+2) and (n+4);
we can suggest this inequation:
84<n+(n+2)+(n+4)<96
Now, we solve this inequation:
84<n+(n+2)+(n+4)<96
84<3n+6<96
1)
3n+6>84
3n+6-6>84-6
3n>78
3n/3>78/3
n>26
2)
3n+6<96
3n+6-6<96-6
3n<90
3n/3<90/3
n<30
The solution is:
26<n<30
Then: n=28
The numbers will be: 28,30 and 32.
Answer: A
Explanation:
Use formula a^2 + b^2 = c^2 but in this case letter “d” will substitute for “b”
Since 13 is hypotenuse, 13 is going to be the letter c
12 is “a” because we don’t know “d”
So it’s 12^2 + d^2 = 13^2
Simplify: 144 + d^2 = 169
Subtract to isolate d^2: d^2 = 25
Take square root from both sides to isolate d: d = 5
Answer: A
Answer:
40,000
Step-by-step explanation:
because 40% of 100 is 40 and 40% of 100,000 is 40,000
