Answer:
"The expression will always equal m" is true about the quotient of
÷
Step-by-step explanation:
Let us solve the question
∵ The expression is
÷ ![\frac{1}{n}](https://tex.z-dn.net/?f=%5Cfrac%7B1%7D%7Bn%7D)
→ In the division of fractions, we change the division to multiplication
and reciprocal the fraction after the division sign
∵ The reciprocal of
is
∴
÷
=
× ![\frac{n}{1}](https://tex.z-dn.net/?f=%5Cfrac%7Bn%7D%7B1%7D)
→ In the multiplication of fractions, we can simplify the terms in
the numerators by the terms in the denominators
∵ There is n in the numerator and denominator
∴ Cancel n up and down
∴
×
= ![\frac{m}{1}](https://tex.z-dn.net/?f=%5Cfrac%7Bm%7D%7B1%7D)
∴
×
= m
∴
÷
= m
∴ The quotient is m
∴ The expression will always equal m
So square feet is area which is legnth times width or area=lw or a=lw
width=w=2 2/4
2/4=1/2
w=2 1/2=5/2
a=lw
11 11/16=187/16
187/16=l(5/2)
multiply both sides by 2/5 to clear the fraction (1/2 times 2/1=2/2=1)
374/80=legnth
simplify
374/80=187/40=4 27/40=legnth
legnh must be less than 5 and 4 and 27/40 is less than 5 so it will fit
The formula for the circumference of a circle is:
![c=\pi\times d](https://tex.z-dn.net/?f=c%3D%5Cpi%5Ctimes%20d)
where d is the diameter.
The diameter is twice the radius. Plugging in the given value of the radius we get:
Answer:
Mean = ∑x + standard deviation = 429.21
Step-by-step explanation:
Mean lifespan = 71.45 years
Standard deviation = 12.35 years
Standard deviation= ∂ = x-µ / N
∂ = standard deviation
µ= mean
x = size of year
By using formula of standard deviation:
= 70 – 71.45 / 12.53
Approximately equal to 64.21
Mean = ∑x + standard deviation
= 365 + 64.21
= 429.21
