The answer is C because c=4h. Think of it like this, Chickens equal the number of horses times 4.
Step-by-step explanation:
The Ratio is given as 100:1
Which means In 1 minute you travelled 100 steps
Therefore,
- In 2 minutes you will travel = 2×100 = 200 steps
- In 3 minutes you will travel = 3×100 = 300 steps
- In 4 minutes you will travel = 4×100 = 400 steps
Answer:
1.778 times more or 16/9 times more
Step-by-step explanation:
Given:
- Mirror 1: D_1 = 8''
- Mirror 2: D_2 = 6"
Find:
Compare the light gathering power of an 8" primary mirror with a 6" primary mirror. The 8" mirror has how much light gathering power?
Solution:
- The light gathering power of a mirror (LGP) is proportional to the Area of the objects:
LGP ∝ A
- Whereas, Area is proportional to the squared of the diameter i.e an area of a circle:
A ∝ D^2
- Hence, LGP ∝ D^2
- Now compare the two diameters given:
LGP_1 ∝ (D_1)^2
LGP ∝ (D_2)^2
- Take a ratio of both:
LGP_1/LGP_2 ∝ (D_1)^2 / (D_2)^2
- Plug in the values:
LGP_1/LGP_2 ∝ (8)^2 / (6)^2
- Compute: LGP_1/LGP_2 ∝ 16/9 ≅ 1.778 times more

Step-by-step explanation:
Step-by-step explanation:
when given a ratio like this 4:7, it means that one item represents 4 units, and the other 7 units.
let's assume that length is larger than width, so the given 31.5 in are these 7 units.
that means 1 ratio unit is
31.5 / 7 = 4.5 in
the width is 4 units, therefore
width = 4×4.5 = 18 in
the perimeter is
2×length + 2×width = 2×31.5 + 2×18 = 63 + 36 = 99 in
the area is
length × width = 31.5×18 = 567 in²
