Answer:
Step-by-step explanation:
You should place a point on the graph at 4 for four hours of TV last week. And place a point at 8 for eight hours of TV this week.
Basically, shift each coordinate one unit to the right (one X over)
You will have to predict the points a little
1. A) 5 (It would be B. because it does equal 4.09 but it has to be 5 because it is the greatest integer in all of them)
2. D) 10 (Just like 1. it would be B. also BUT 10 is the greatest integer you can have out of all of them)
3. A) 6 (Just like the other 2 problems at the top^ it would be C. if not for the fact it has a higher number.)
4. A) A value we can put in place of a variable (such as x) that makes the equation true.
Angle A = 30 and its complement would be 60. This is because both angles must equal 90 degrees, and 30 + 60 = 90. Also in the directions it states Angle A must be half of its complement. 30 is half of 60. Sorry I don’t have any work, I just did it in my head!
Any questions? Hope this helps!
I found the image that accompanied this problem.
We need to solve for the area of the sector.
A = n/360 * π * r²
A = 85/360 * 3.14 * 5²
A = 0.2361 * 3.14 * 25
A = 18.5347
Answer is C. 18.5 square meters.
