Scientific notation:
8.41 x 10^7
expanded form:

Answer:
168
Step-by-step explanation: You would do 140/100 = 1.4 then multiply 120 by 1.4 which is 168.
Answer:
Ratios are proportional when the numbers in the ratio are multiply or divide by the same number. Ex. 3:5 = 6:10 = 12:20 = 9:15 (cross multiply the fractions and the results are the same 3/5 = 6/10)
Step-by-step explanation:
Answer:
(2) (100, 300)
Step-by-step explanation:
One wave can be divided on 4 parts, as show on the picture.
Since a length of one whole wave equals 400, a length of each part is
nanometers.
The height of the wave is decreasing on the second and on the third part, hence over the interval (100, 300).
X is 180 - 30 = 150,
The sum of the sides of a polygon is the (number of sides - 2) * (180) so the total interior angle measure of the right polygon is 360.
360 = 80 + 90 + 150 + y
x = 150
y = 40
