The answer is 270 degrees.
Since a circle has a full degree measure of 360 degrees, we can multiply 360 by 3/4 to result in 270 degrees.
Hope this helps.
If Ann cleans in 12 hours then she cleans
of the apartment per hour. Similarly Liz cleans
of the appartment per hour. So together then can clean
of the apartment for hour. Therefor it will take them
hours to clean.
The general formula
can be used as a check if needed.
Answer:
4cm^2
Step-by-step explanation:
First we need to find the length of the height of the triangle using Pythagoras:
a^2+b^2=c^2 (Substitute in what we have)
a^2+3√2(^2)=2√5(^2) = a^2 + 18 = 20 -> 20-18=2 √2=BD
Now we can find the area:
AD+DC= 3√2 + √2 = 4√2 x √2 = 8/2 = 4
Answer:
For example, LCM(2,3) = 6 and LCM(6,10) = 30.
I think you mean x^2 - 7x + 8
This is a basic factoring problem:
What two numbers multiply to make 8 and add to make -7?
There are no two numbers that work!
Therefore, it is prime
