Answer:
1/10
Step-by-step explanation:
First, find the probability of choosing the red pen:
There are 6 total pens and 3 are red, so the probability will be 3/6
This can be simplified to 1/2
Then, find the probability of choosing a blue pen after not replacing the red one:
There are 5 total pens now, since we did not replace the red one.
There is only 1 blue pen, so the probability is 1/5
Then, multiply these 2 probabilities together:
1/2(1/5)
= 1/10
So, the probability is 1/10
Answer:
If two planes intersect, they intersect in a line. Two planes that do not intersect are called parallel. Given a plane and a line, there are three possibilities. The line and the plane intersect in a single point.

Answer:
4 11/16 m²
Step-by-step explanation:
The formula for the area of a rectangle = Length × Width
From the question:
Length = 1 1/4 m
Width = 3 3/4m
Area of the rectangle =
1 1/4 m × 3 3/4 m
= 5/4 m × 15/4 m
= 75/16 m²
= 4 11/16 m²
Area of the rectangle = 4 11/16 m²
Answer:
The area is 28.27cm²
Step-by-step explanation:
Answer:
46
Step-by-step explanation:
If you take the fraction and divide it 2/11, it'll give you the decimal form of what you need, which will give you .18
Now your equation has become 254*.18, which you multiply instead of divide because you switched the form it is given in, and if you try to divide it will give you some obscure number.
Your answer from 254*.18 is 45.72, which you cant give .72 of a book, therefore you round up, making it so he has donated 46 books.
