Slope is found by the formula (y2 -y1) divided by (x2 - x1). We plug in the numbers, and get ((-2) - 2) divided by (6 - (-3)). So the slope will be -0.44
Answer:
Step-by-step explanation:
Since the time for the pot of water to boil is inversely proportional to the cooker setting, H, as one goes up, the other must go down:
Convert 5 minutes to seconds:
Therefore, from the initial data given (When H=6, T=90), the new time is larger. Therefore, H must be times <em>smaller </em>for them to be inversely proportional.
Answer:
50,020 revs to nearest rev.
Step-by-step explanation:
r = 1/2 * diameter
Circumference of the wheel = 2 pi r
= 2 * pi * 1/2 * 77
= 77pi cms
1 km = 1000 * 100 cms so
The number of revolutions = (121 * 100 * 1000) / 77pi
= 50,020 revs to nearest rev.
I think all you have to do is add all the numbers up. I am sorry if I am wrong about my answer.
Answer:
2bricks
Step-by-step explanation:
volume of cuboid = length × breadth ×height
step 1 : calculate the first one
v= 15cm ×8cm× 5cm = 1200cm^3
step 2 calculate the 2nd one
v= 15cm ×10cm×8cm = 600cm^3
number of bricks
1200cm^3 × 1bricks/ 600cm^3 = 2 bricks
