Answer: 20

Work:
Here, you could make a proportion. 

 6      x
---- x ----
30    100 

6 * 100 = 600
30 * x = 30x

600 / 30 = 20

Hi!

So we know that there are 30 people over 100, and 6 of them are male. That means the the rest are female. We just have to find out how much the rest is. 

To do that, we subtract
30-6 = 24

The answer is 24.

Hope this helps! :)

If it takes 6.9 pounds of seed to plant one acre of grass , how many acres can be planted with 8.28 pounds of seeds
Vaselesa [24]
There's 1.2 times as much seed, so you can plant 1.2 times more land.

1.2x1=1.2

So you can only plant 1.2 acres.

S(x)=5x+5<br> T(x)=_3x +4<br><br> The value of t(s(2))
irina1246 [14]

Answer:

Step-by-step explanation:

This is a composite function, in which we will first evaluate the s function at a value of 2, then we will use that value in the t function.

s(2) = 5(2)+ 5 so

s(2) = 15. Now we evaluate the t function at 15:

t(15) = 3(15) + 4 so

t(15) = 49

Consider the function f(x)=3x^3-5x^2-88x+60-5 is a root of f(x). Find all of the roots of f(x)
Tom [10]
If -5 is a root then f(x) is divisible by x + 5

The quotient from this division is 3x^2 -20x +12
Factoring this:-

= 3x^2 - 18x - 2x + 12
= 3x(x - 6) - 2(x - 6)
= (3x - 2)(x - 6)
So 2 more roots are 2/3 and 6
All the roots are -5 , 2/3 and 6.  Answer
