Answer:
3 people attended the banquet
Step-by-step explanation:
The function is given as:
b = 75 + 15n where
b represents the total = 122
n represents the number of people attending = ??
If the total cost of the banquet is 122, how many people attended the banquet?
Hence,
122 = 75 + 15n
122 - 75 = 15n
47 = 15n
Divide both sides by 15
n = 47/15
n = 3.1333333333
Approximately to the nearest whole number = 3
Therefore, 3 people attended the banquet.
Answer:
a=L² is is the formula for the area of square. where L represent the length.
a=(12cm)²
a=144cm²
p=4(L) is the formula for the perimeter of a square. where L represent the length
p=4(12cm)
p=48cm
N is equal = 36
Or
n = 6^2
Because,
x^2 + 12x + 36 = x^2 + 2.6x + 6^2
= ( x + 6)^2
<span>The area to be determined is a segment of the circle.
Since central angle is 120 degrees and 120/360 = 1/3
area of sector of circle is (1/3)*36pi = 12pi
For the area of triangle, you can split it into 2 30-60-90 right triangles with sides 3:3sqrt3:6
thus base of triangle is 6sqrt3 and height is 3
Area = 1/2 * 3* 6sqrt3 = 9sqrt3 -->
segment area = 12pi - 9sqrt3</span>
Step-by-step explanation:
Let x be the number of roses Mr Charles had cut from his garden.
After giving 10 roses to his neighbour, he has (x - 10) roses.
After giving half of the remaining roses to his niece, he has (x - 10)/2 roses left.
We are given that (x - 10)/2 = 14.
=> x - 10 = 28, x = 38.
Hence Mr Charles had cut 38 roses.
