Answer & Step-by-step explanation:
For this problem, we will use the distance formula.
For our (x1, y1), we will use (-3, 1). For our (x2, y2), we will use (1, 5). Now let's plug in our numbers and solve the problem.
So, the distance between (-3,1) and (1,5) is 5.657 units.
Answer:
19d + 11
Step-by-step explanation:
7(d + 2) - 3 (1- 4d)
Expand the brackets.
7d + 14 - 3 + 12d
Add or subtract like terms.
7d + 12d + 14 - 3
19d + 11
Answer:
Divide the total number of pieces by the cost. If you don't know the number of pieces, then you can do it by weight instead. Remember to use the same units.
Answer:
69%
Step-by-step explanation:
If the diameter is increased by 30%, it is effectively multiplied by the factor ...
1 + 0.30 = 1.30.
Volume is proportional to the square of the diameter, so the larger can's volume is ...
(1.30)² = 1.69
times that of the smaller can. That is, 0.69 = 69% of the volume of the smaller can has been added to make the volume of the larger can.
The volume of the larger can is 69% more than that of the smaller can.
2x +8=2x+8
2x-2x=8-8
0x=0
So the answer is 0
