The most common ways is to indicate orders of magnitude through multiplying by powers of 10. I expect you’re at least seen something like 6.022∗1023
show up in your texts. The important part for this discussion is 1023
, because it gives us an idea of just how large this value is. If we wrote it all out, it would be: 602,200,000,000,000,000,000,000. You can do the same thing in the other direction, too. 10−28
Common value for certain types of physics, but a very, very small one.
Alternately, when dealing with probability, the function for determining the probability of series of independent events with the same odds is
where p is the probability of a certain outcome and n is the number of times the event occurs. For example, if we want to know what the odds of getting five heads in a row while flipping a coin we’re looking at 125
or 132
But the thing with powers of 10 is the most common I’ve seen, it even occasionally gets named Scientific Notation.
THe LCD is x(x^2 - 4)
so multiplying through by this we get:-
2x(x + 2) + 7x = 5(x^2 - 4)
2x^2 + 4x + 7x = 5x^2 - 20
3x^2 - 11x - 20 = 0
(3x + 4)(x - 5 ) = 0
so x = 5 , -4/3
Its the second choice
Answer: C.
Step-by-step explanation:
An isosceles triangle is a type of triangle that has two identical sides and angle measures. Knowing that the two sides creating the 44 degree angle are equal, you can also know that both remaining angles are equal.
All three angles in a triangle must add to 180, so you can solve for f through this equation:
2f + 44 = 180
2f = 136
f = 68
Answer
they would need to sell 200 chocolate bars
Step-by-step explanation:
500 divided by 2.50 = 200
2 x 200 = 400
.50 x 200 = 100
400 + 100 = 500
