Answer:
ratio of adults to children in SIMPLEST form would be 3:7
Step-by-step explanation:
To simplify a ratio you have to find the Greatest Common Factor (GCF) of each number in the ratio and divide. In this example, the original ratio would be 24:56 the GCF of 24 would be 9, and the GCF of 56 would be 8. And then you would divide those numbers and get 3:7
Answer:
the correct answer is B
Step-by-step explanation:
The formula of cone's capacity is V = (1 / 3) (pi x r x h)
we know that r = 3.5, we must find h, the slant height is H=6.5, applying pythagorean theorem h ^2 = H^2, so h= sqrt (H^2 - r^2)
h = sqrt (6.5^2 - 3.5^2) = 5.47
finally, V = (1 / 3) (3.14 x 3.5 x 5.47) = 20.03 cm^3
the surface are is A = pi x r x H = 71.43 cm^2
Answer:
Option C.
Step-by-step explanation:
We start with the expression:
where y > 0. (this allow us to have y inside a square root, so we don't mess with complex numbers)
We want to find the equivalent expression to this one.
Here, we can do the next two simplifications:
And:
If we apply these two to our initial expression, we can rewrite it as:
Here we can use the second simplification again, to rewrite:
So, concluding, we have:
Then the correct option is C.
