The correct answer is the last one
Answer:
Step-by-step explanation:
The formula of a slope:
We have the points (-3, 5) and (-1, 4). Substitute:
<u>Question 6</u>
1) , , O is the midpoint of , (given)
2) are right angles (perpendicular lines form right angles)
3) are right triangles (a triangle with a right angle is a right triangle)
4) (a midpoint splits a segment into two congruent parts)
5) (LL)
<u>Question 7</u>
1) are right angles),
2) (reflexive property)
3) are right triangles (a triangle with a right angle is a right triangle)
4) (LL)
5) (CPCTC)
<u>Question 8</u>
1) , point D bisects (given)
2) are right angles (perpendicular lines form right angles)
3) are right triangles (a triangle with a right angle is a right triangle)
4) (definition of a bisector)
5) (reflexive property)
6) (LL)
7) (CPCTC)
We know that his woodshed is a parallelepiped, and 8' is the depth, 16' is the lenght and 6' is the height.
A cord of wood is 4' high, 4' deep and 96" long.
96" = 8'
We find the volume of his woodshield.
V = h*d*l = 168*6 = 768 cubic feet
Find the volume of a cord
4*4*8 = 128 cubic feet
Do the ratio: 768/128 = 6
His woodshield can hold 6 cords.
For the second question, simply do a multiplication.
If 1 cord is $120, how much are 6?
120*6 = $720
1:45 ------> starting time
add an hour and a half
1:45-----> 2:45 -------> 3:15
another two hours
5:15 --------> ending time
