Answer:
Perpendicular
Step-by-step explanation:
First note:
- Parallel lines have equal slope
- Perpendicular lines have slopes that are negative reciprocal to each other
Lets check, first we need to convert them to slope intercept form (y = mx + b), where m would be the slope.
L1:
4x + 5y = 15
5y = -4x + 15
y = -4/5x + 3
L2:
4y = 5x - 12
y = 5/4x - 3
Slope of L1 is -4/5 and Slope of L2 is 5/4
<em>Are they negative reciprocals of each other? Yes, because multiplying the slopes would give us "-1"</em>
<em></em>

So the lines are Perpendicular
It’s A because when u do (6.4)^2 times pi equals 128.6796351 and u subtract to the total volume(1119.5cm) and equals to 8.69; u later round to nearest tenth which equals to A, 8.7cm
Answer:
The number of times Abigail is faster on her skateboard than she is walking is 2 times faster
Step-by-step explanation:
Let the distance to Abigail's home = D
The distance Abigail had traveled before hr skateboard broke = 2/3·D
The distance from home where the skateboard broke = D - 2/3·D = 1/3·D
The time it took Abigail to walk the 1/3·D home = Twice the time it will take her if she was on her skateboard
Let the time it will take Abigail to travel the 1/3·D home on her skateboard = t
Therefore;
The time it took Abigail to walk the 1/3·D home = 2 × t
The speed of Abigail walking, = Distance/Time = 1/3·D/(2 × t) = D/(2·t)
The speed of Abigail skateboarding, = Distance/Time =D/t
The ratio of the speed of Abigail skateboarding to the speed of Abigail walking =
Therefore, Abigail is two times faster on her skateboard than she is walking.
Answer: The answer to your question is B.
Step-by-step explanation:
Answer:
The height of cylinder is 10 meters.
Step-by-step explanation:
Given
Curved Surface Area = 44m^2
Radius = r = 0.7 m
The curved surface area of a cylinder is given by:
Putting the values we get
Pi can be taken as 22/7 or 3.14
We are taking 22/7 for the question
Hence,
The height of cylinder is 10 meters.
