1) Option C is correct
2) Option B is correct
Step-by-step explanation:
Question no 1:
We need to find the constant of proportionality
The constant of proportionality can be found by using the formula y/x = k, where k is the constant of proportionality.
Finding k:
x = Hot pepper corn
y = chedder corn
So, y/x = 10/4 = 2.5
y/x = 20/8 = 2.5
y/x= 30/12= 2.5
So, Constant of proportionality is k = 2.5
Hence Option C is correct.
Question No 2
Every female rabbit has 5 baby rabbits. We need to find ratio of baby rabbits to female rabbits.
Baby rabbits = 5
female rabbits = 1
Ratio of baby rabbits to female rabbits: 5: 1 or 5/1 = 5
So, ratio of baby rabbits to female rabbits is 5
Option B is correct.

Answer:
4989600 ways
Step-by-step explanation:
From the question,
The word MATHEMATICS can be arranged in n!/(r₁!r₂!r₃!)
⇒ n!/(r₁!r₂!r₃!) ways
Where n = total number of letters, r₁ = number of times M appears r₂ = number of times A appears, r₃ = number of times T appears.
Given: n = 11, r₁ = 2, r₂ = 2, r₃ = 2
Substitute these value into the expression above
11!/(2!2!2!) = (39916800/8) ways
4989600 ways
Hence the number of ways MATHEMATICS can be arranged without duplicate is 4989600 ways
Answer:
Step-by-step explanation:
Answer:
(a). 2.251 cm
, 2.349 cm, 2.295 cm
(b). 0.023 meters.
Step-by-step explanation:
(a). We are asked to to choose the options that shows the actual measurement of the rainfall.
Since the rounded figure is 2.3 cm, this means that either the tenths digit is 3 with hundredths digit less than 5, or tenths digit is 2 with hundredths digit greater than or equal to 5.
Let us check our given choices one by one.
Therefore, the correct choices are 2.251 cm
, 2.349 cm and 2.295 cm.
(b) We know that 1 cm equals 0.01 meters.
To convert 2.3 cm to meters, we will multiply 2.3 by 0.01.
Therefore, the rounded measurement of rain would be 0.023 meters.
