how many multiple- choices questions did tanika get correct
How many boxes must she buy to cover the floor?
A. 1 box
B. 2 boxes
C. 3 boxes
D. 4 boxes
Answer:
B. 2 boxes.
Step-by-step explanation:
Area of the floor = 7 1/2 * 8 5/6
= 15/2 * 53/6
= 265/4 feet^2.
Now we divide this are by 1 square foot giving a total of 265/4
= 66.25 tiles
so she needs 2 * 45 tiles boxes (answer).
B = {(2, 4), (−1, −7), (5, 6), (4, 3)}
Only A
Only B
Both A and B
Neither A nor B
Answer:
Both A and B
Step-by-step explanation:
A = {(3, −5), (4, 6), (−3, 9), (2, 7)}
-Each x goes to a different y so this is a function
B = {(2, 4), (−1, −7), (5, 6), (4, 3)}
-Each x goes to a different y so this is a function
Both!!
If you look at it, none of the x values are repeating with a differnt outcome, so you know that they both are correct.
