Answer:
It will be solved by the method
Answer : option C
An electrician is hired to install a ceiling fan. She estimates that the installation will take no more than 45 minutes if the house is up to building code. The installation will take 45 minutes or less than 45 minutes. So we put a solid circle at 45 and shade to the left.
If the house is not up to building code, she estimates that the installation will take longer than 120 minutes. The installation will take more than 120 minutes. So we put a hollow circle at 120 and shade to the right.
So third diagram is correct.
Answer: 24
Step-by-step explanation:
Okay, so if the part-time designer gets 200 dollars per week, we should subtract 200 by 800.
800 - 200 = 600.
Then we divide 600 by 25, and that will be the amount of completed designs we'll be able to have each week.
600 ÷ 25 = 24.
So in conclusion, you can pay the designer $200 per week and get 24 completed designs from him.
Hope this helps!
You split it into 2 shapes.
So the simplest way to split it up is splitting it into 2 rectangles of 2x3 and 3x7
So then, the are of the whole figure would be 6+ 21 = 27 square units.
The perimeter would be 2+3+3+5+7 = 20 units.
(By the way to find the length of the black side, you add up the number on the opposite side, 2+3 = 5)
