84 slices were sold individually.
364 - 84
The rest were sold as a pie
(364 - 84) ÷ 8
Answer D (But it should either be in a bracket or write as a fraction with the numerator as 364 - 84)
the middle one is a rate of 2.5
If one-sixth of a certain number is four more than one-twelfth the number, the required number will be 48.
Let the unknown number be 'a'
One-sixth of the number is expressed as 1/6 a ..... 1
One-twelfth the number is also expressed as 1/12 a
Four more than one-twelfth the number will be written as:
1/12 a + 4 .... 2
Equating 1 and 2 will give:
1/6 a = 1/12 a + 4
a/6 = a/12 + 4
Collect the like terms
Find the LCM
Cross multiply
a = 12×4
a = 48
This shows that the required number is 48

ANSWER
EXPLANATION
We have been given the quotient,
to simplify.
We need to rewrite the numerator as difference of two cubes.
We need to make use of the difference of cubes formula,
We now let,
Then the numerator becomes,
This simplifies to,
We cancel out common factors to obtain,
Answer:
∠ L ≈ 52°
Step-by-step explanation:
Using the cosine ratio in the right triangle
cosL = = = , then
∡ L = ( ) ≈ 52° ( to the nearest degree )
