Answer:$13.50
Step-by-step explanation:
First thing you want to do is find what is 6% of 14.31. You can find this using your calculator and putting the percentage in decimal form then multiplying it by the given amount. 0.06 x 14.31 = ? And then you take that number and subtract it from 14.31.
Answer:
62mm
Step-by-step explanation:
Add each side together, check answer.
Start by adding 17 and 10 together. Break it down and that equals 27. Add 11 and you get 38. Add 19 and 5 to get 24 and add that to 38. Answer, 62mm.
Step-by-step explanation:
let the unknown members be X
At first, the club had 20 + X members
After the first year,
2( 20+X)
The second year,
2( 20 +X/2) +40
The third year,
3[2(20+ X/2) +40]
Total number =
20+X + 2(20+X) + 2( 20 +X/2) +40 +3[2(20+ X/2) +40]
= 20+ X + 40+ 2X + 40 +2X/2 +40 +3[40+2X/2 +40]
= 20+40+X +2X +40+X+ 40 + 3[ 40+40+X]
= 60 +3X +80+X + 3[80+X]
= 140+4X + 240+3X
=380 + 7X
-380=7X
X = -54.3
If you want to know if a function is odd, you look at the exponents/degrees it has; if they're all even it's an even function if they're all odd it's an odd function if it has a mix of both even and odd its neither
the function 9-4x^2 only has one x with an exponent of two making it even
