Answer: True
Step-by-step explanation:
We try to keep the number greater than 1 and lower than 10, so between 1, and 9.
For example: 3545346 would be 3.5x10^6
you can see 3.5 is between 1 and 9

The wave length of the sound with parameters frequency of 125 Hz and a speed 5000 m/s is 40 meters
<h3>Given Data</h3>
velocity = 5000 m/s
frequency = 125 Hz
wavelength = ??
We know that the relationship between speed, frequency and wavelength is given as
v = fλ ----------------------------1
substitute our given parameters
5000 = 125 * λ
Divide both sides by 125
λ = 5000/125
λ = 40 m
Hence the wave length of the sound is 40 meters

Answer:
m = -2
Step-by-step explanation:
24 = -6(m + 1) + 18 (Given)
24 = -6(m) + -6(1) + 18 (Distributive Property of Equality)
24 = -6m - 6 + 18 (Simplify)
24 = -6m + 12 (Simplify)
24 - 12 = -6m + 12 - 12 (Subtraction Property of Equality)
12 = -6m (Simplify)
(Division Property of Equality)
-2 = m (Simplify)
m = -2 (Distributive Property of Equality)
Answer: Choice B) x < 10
=======================================================
Explanation:
There's 300 square feet total (land+water). Of that, 100 sq ft is taken up by the pond, so we have 300-100 = 200 sq ft of dry land.
1 duck needs more than 20 sq ft of dry land
2 ducks need more than 40 sq ft of dry land (note how 2*20 = 40)
3 ducks need more than 60 sq ft of dry land (note how 3*20 = 60)
and so on...
In general,
x ducks need more than 20*x square feet of dry land
The max amount of dry land we have is 200 sq ft
The total amount of space the ducks take up must be less than 200 sq ft
In terms of symbols, we have
T = total space ducks take up on dry land
T = 20*x
T < 200
So we can arrive at this inequality
20*x < 200
after replacing the "T" with "20*x"
Afterward, divide both sides by 20
20*x < 200
20*x/20 < 200/20
x < 10
So we must have less than 10 ducks
If we had 10 ducks exactly, then they would take up more than 20*10 = 200 sq ft, but we only have 200 sq ft
The largest number of ducks we can have is 9 ducks.
So that's why we have a "less than" symbol instead of a "less than or equal to" symbol.
