Answer:
41 cookies in the box are not sugar cookies
Step-by-step explanation:
First, find what percentage of the total cookies <u>aren't</u> sugar cookies. If 18% are, then the amount that aren't is:
100% - 18% = 82%
Since 82% of the cookies aren't sugar cookies, multiply 82% by 50 to find the amount of cookies that aren't sugar cookies:
50 * 82% = 41
Answer:
41
Step-by-step explanation:
first work out how many of the total cookies are 1%. To calculate this, divide the total by 100
50 ÷ 100 = 0.5 (1% of the cookies is 1/2 a cookie)
As 18% of these cookies are sugar cookies, multiply the 1% by 18
0.5 x 18 = 9 (9 of the cookies are sugar cookies)
To work out how many are NOT sugar cookies, subtract the sugar cookies from the total
50 - 9 = 41
∴41 of the cookies were NOT sugar cookies
I hope this helped :-)

Answer:
f(- 6) = 70
Step-by-step explanation:
To evaluate f(- 6) , substitute x = - 6 into f(x)
f(- 6) = 2(- 6)² - 2 = 2(36) - 2 = 72 - 2 = 70
