Answer:... what is it?
Step-by-step explanation:
For the equation of the line expressed as Ax + By + C = 0, the value of the slope (m) is calculated by -A / B. For perpendicular lines, the slope of one should be the negative reciprocal of the other. From the choices given, the lines that are perpendicular is Option A.
Answer:
0.52 km
Step-by-step explanation:
We are given that
Speed of object, v=
Speed of object, v=
Distance travel by object, s=
Distance travel by object, s=
We have to find the time taken by object to travel 5 1/10 km.
We know that

Using the formula
Time taken by object to travel 5.1 km =
Time taken by object to travel 5.1 km=0.52 hr
Answers
Surface area is 964 cm2
Volume is 1872 cm3
Step by step
Using L=length, w=width, h= height
Surface area is found by adding the area of all 6 sides. Area is found by multiplying L x W.
8x18 = 144 x2 sides = 288
18x13 = 234 x2 sides = 468
8x13 = 104 x2 sides = 208
Total all sides = 964
Volume of a rectangle is found by multiplying L x W x H
13 x 18 x 8
Volume is 1872 cm3
