Answer:
The correct answer is -7.5 years.
Step-by-step explanation:
Given:
Principle amount = 12000
Interest = 4320
time = ?
rate = 4.8 simple interest
Solution:
We know that simple Interest I = (P*t*r)/100
then t = I*100/p*r
putting values in formula:
t = 4320*100/4.8*12000
= 432000/57,600
= 7.5 years
ANSWER:
7 / 80
8 3/4% expressed as a fraction is 7 / 80.
STEP-BY-STEP EXPLANATION:
Write 8 3/4% as a percentage with a decimal:
= 8.75%
Convert 8.75% to a fraction:
= 8.75% ÷ 100
= 8.75 / 100
Make the numerator a whole number by multiplying both the numerator and denominator by a 100:
= ( 8.75 × 100 ) / ( 100 × 100 )
= 875 / 10000
Divide the numerator and denominator in the fraction by their highest common factor ( HCF ):
HCF = 125
THEREFORE:
= ( 875 ÷ 125 ) / ( 10000 ÷ 125 )
= 7 / 80
Bisect means it cuts the angle, but in halves.
angle BFD is 60°, and Line FD bisects,
Angle CFD is 30°
