Answer:
The original number = 48.8
Step-by-step explanation:
Let the number be x.
According to the question ,
x + 0.085 x = 53
⇒ 1.085 x = 53
⇒ x = 48.8479 = 48.8
The axis of symmetry of h(x) = 5x2 + 40x + 64 = -4
The formula for calculating the axis of symmetry is expressed as:
Axis of symmetry x = -b/2a
h(x) = 5x^2 + 40x + 64
a = 5 and b = 40
Answer:
8
Step-by-step explanation:
total number of pencils = 186
number of students = 23
number of pencils each student gets = number of pencils ÷ number of pencils
=186/23
=8.08
so each student gets 8 pencils
