Answer:
-14/3
Step-by-step explanation:
Use derivative = 0 to find turning point(S)
D f(x) = 3x + 10 = 0
3x = - 10
X = - 10/3
When X = - 10/3
F(x) = 1.5(10/3)^2 - 10(10/3) + 12
= (3*10*10) / (2*3*3) - 100/3 +12
= 50/3 - 100/3 + 36/3
= - 14/3
Answer:
1/20=10 years old
In a school 50% of the students are younger than 10, 1/20 are 10 years old and 1/10 are older than 10 but younger than 12, the remaining 70 students are 12 years or older. How many students are 10 years old?
50%= younger than 10
1/20=10 years old
1/10=older than 10 younger than 12
70=12 years or older
50%- 10/20
1/20-1/20
1/10-2/20
10/20+1/20+2/20=13/20
70 students =7/20
1/20 = 10 years old.
7/20 divided by 7 = 1/20
70 divided by 7=10
10 students are 10 years old
9*6 = 54 which is also divisible by 2 and 3
another one would be 2*54 = 108
Answer 54 and 108.
Answer:
3
Step-by-step explanation:
so you can see it more boldly
explained in the comment thing.
27 since 27 is a factor of 54
