The ratio of interest can be found for collinear points by considering only one of the coordinates. Let's look at the x-coordinates.
(Tx -Mx)/(Dx -Mx) = (1-(-3))/(9-(-3)) = 4/12 = 1/3
Then the ratio of interest is MT:MD = 1:3.
Answer:
4
Step-by-step explanation:
The answer is the 4th one
Answer:
C. 4
Step-by-step explanation:
A pancake is circular in shape
Hence, the area of a circle = πr²
HenceThe corner shop charges
a) $12 for a 3-inch personal pancake.
For personal pancake
r = 3 inches
πr² = π × 3²
= 28.274333882 square inches
= 28.3 square inches
b) The largest pancake is a 6-inch pancake that costs $20.
For Largest pancakes
r = 6 inches
πr² = π × 6²
= 113.09733553 square inches
Approximately = 113.1 square inches
How many times larger is the area of the largest pancake than the personal pancake?
This is calculated as :
Largest pancake/Personal pancake
= 113.1/28.3
3.9964664311 inches
Approximately = 4
Option C is the correct option
Answer:
31.5 hours
Step-by-step explanation:
Given that 1 unit of electricity is consumed in 3 hours by 1 fan, it means that 2 fans will consume 1 unit in
= 3/2 hours
= 1.5 hours
If 2 fans consume 1 unit in 1.5 hours then 21 units will be consumed in
= 21 * 1.5/1
= 31.5 hours
It means he used the fans for 31.5 hours
