Answer: In scientific notation, 100,000 is
Step-by-step explanation:
We know that the scientific notation is a technique to describe a very large or a very small number in the product of a decimal form of number [generally between 1 and 10] and powers of ten.
The given number = 100,000
Here the number of zeroes = 5
Then, in scientific notation, 100,000 =

Answer:
It was used as scale factor.
Step-by-step explanation:
The scale factor is the ratio of two corresponding side lengths of similar figures. Similar figures have the same shape but are of different sizes.
To find the scale factor that was used when going from the grey triangle to the yellow triangle we can work with any of the three sides of the grey triangle.
Let's work with the below side.
The below side is extended from the point to the point
The length of this side is 9 units.
In the yellow triangle, we can see that the below side is extended from the point to the point
The length of this side is 3 units.
Working with the lengths and the scale factor ⇒
We find that the scale factor that was used when going from the grey triangle to the yellow triangle is

The probability that the spinner stops at purple and a pink card is selected is 80%.
We have given that,a spinner with 5 equal sectors is shown in the figure.
What is the formula probability?
The spinner has a 1/5 chance of landing on purple, since the number of favorable outcomes is the numerator, and the number of possible outcomes is the denominator.
There are total four cards, which means we have a 1/4 chance of picking pink,
for the samereason as above.
Therefore 1/5 x 1/4 = 4/5
4/5 =0.80= 80% chance.
