Answer:
with a line accross the points
Answer: 19
Step-by-step explanation:
75 papers need to be marked
He grades 7 papers per hour
To find out how many paper he graded in 8 hours:
7 x 8
(7 is the number of papers graded in an hour)
(8 is the number of hours)
7 x 8 = 56
(56 is the number of papers he graded in 8 hours)
Now, there was a total of 75.
To find the remaining number of test sheets:
75 - 56
(75 is the total number of papers)
(56 is the number of papers graded)
75 - 56 = 19
Therefore, there are 19 papers remaining to grade.
Answer:
2n= 53
and you divide both sides by 2
2n/2 =53/2
2 divided by 2 is 1 and 53 divided 2 is 26.5
n= 26.5
We can use the distance formula to calculate perimeter: 
= Distance
From A to B: √232
From B to C: 10
From C to A: √52
10 + √232 + √52 = 10 + 2√58 + 2√13
Perimeter = 10 + 2√58 + 2√13 units
For Area we can use matrices, but since one of the sides is horizontal, we can just calculate with distance formula and area of triangle formula.
The area of a triangle formula is 1/2(h x b)
h=height
b=base
So the height is 6 and the base is 16. (I graphed it.)
16 * 6 = 96 96/2 = 48 Area: 48 square units.
