Whatever happened to just normal 70 times 6,000? The product is 420,000. If that was your question.
Answer:
<em>~ 0.375 centimeters of the snowflake in real life ~</em>
Step-by-step explanation:
Let us plan out our steps, and solve for each:
<em>1. Given the information, let us create a proportionality as such:</em>
48 = 1 ⇒ x - centimeters of the snowflake in real life
18 x
<em>2. Now let us cross multiply, and solve through simple algebra for x:</em>
48 * x = 18,
x =<em> 0.375 centimeters of the snowflake in real ife</em>
Answer: 90
Step-by-step explanation:
set: {1, 2, 3, 4, 5, 6, 7} = 7 numbers | 3 even
no element may be used more than once in a number = distinct elements
and the number must be even = must finish with a even number.
This way, we should start with the last number, which we have 3 possibilities.
Since we have 7 numbers in total, we have 6 options for the first one and then 5 options for the second one.
So, we have 6.5.3 = 90
Discriminant = b^2 - 4ac; where a = 1, b = 9 and c = 14
d = (9)^2 - 4(1)(14)
d = 81 - 56
d = 25
the discriminant is greater than zero, so there are two real roots
