Step-by-step explanation:
Using a calculator 
Answer:
8
Step-by-step explanation:
Since 24 is the original length, you would have to see what number to divide by to get 6.
24 divided by 4 is 6.
Now we know that 1/4 is the scale factor, so apply that to 32.
32 divided by 4 is 6
That's your answer!

Answer:
Step-by-step explanation:
Let x be the distance from the foot of the ladder to the base of the building.
We have a right triangle, so we can use Pythagoras' Theorem.
The correct answer is A) 37.4%.
The probability that the first volunteer is a man would be 32/52, since there are 32 men out of 52 people. The probability that the second volunteer would also be a man would be 31/51, since there is 1 fewer man and 1 fewer person total to choose from.
32/51(31/51) = 992/2652 = 0.374 = 37.4%.
First task:
To determine this we need to make difference between system that doesn't have solution and system that has infinite number of solution. If when solving equations we get 0 = 0 that means system has infinite number of equations.
If we get 0 = some number that means that system doesn't have solution.
Multiplying first equation of second system by 2 and adding it to second equation we get 0=0 which means that this system has infinite number of solutions.
Answer is second system
Second task:
For this we need to set a system of equations and solve it. System looks like this:
x + y = 224
x*12 + y*8=2520
-------------------------
x represents older than 18 and "y" 18 and younger than that.
first equation we multiply with -12 and sum it with second.
-4y = -168
y=168/4 = 42
Answer is 42.
