4 0

Answer:

"6 out of 10 people" means the ratio of class:no_class is 6:4

990/10 = 99, the smallest the "class" and the "no_class" add up to is 10. And, generally, the total divides with that nicely, as in this case.

99(6) = 594 ----------- probably class

99(4) = 396 ------------------ probably no class

Total  = 990

I hope this helps

How does using scientific notation help with when multiplying and dividing very large or very small numbers?
kolbaska11 [484]

Answer:

Own words: Writing in scientific notation allows the equation to appear simpler and more approachable.

Step-by-step explanation:

Online Definition: To write a number in scientific notation, if the given number is greater or equals to 10, the decimal point is moved to the left of the number and so, the power of 10 becomes positive. ... Writing numbers in scientific notation not only simplifies them, but also makes them easier to multiply

How do I find the surface area of a right circular cone?
UkoKoshka [18]
Greetings!

"<span>How do I find the surface area of a right circular cone?"...
</span>
The formula to find the surface area of a right cone is :
=\pi r(r+ \sqrt h^2+r^2)

Lets it out:
r=5 and h=12

=\pi(5)((5)+ \sqrt (12)^2+(5)^2)
Follow PEDMAS.
=\pi(5)((5)+ \sqrt 169)
=\pi(5)((5)+ 13)
=\pi(5)(18)
=15.7079633(18)
=282.743339

The SA of the cone would be <span>282.743339.

Hope this helps.
