Answer: 6 cm
Step-by-step explanation:
Use equation for area of triangle
A=a*h/2
a*h=2A
a=2A/h
where a represents base of triangle
h represents height of triangle.
h=12.8 cm
A=38.4 cm²
a=2A/h=2*38.4 cm²/12.8 cm=76.8cm²/12.8cm= 6 cm
Given that the angle measure 20 and the side opposite to that angle measures 10 cm, suppose this is the height of the triangle, the hypotenuse
Such that
sin theta=opposite/hypotenuse
opposite=a=10 cm
sin 20=10/h
multiplying both sides by h we get
hsin20=10
hence;
h=10/sin20
h=29.24 cm
h=29.2 cm
I simply divided by 100 and moved the decimal two places to the left.
Answer: the value of the car will be about $12634
Step-by-step explanation:
We would apply the formula for exponential decay which is expressed as
A = P(1 - r)^ t
Where
A represents the value of the car after t years.
t represents the number of years.
P represents the initial value of the car.
r represents rate of decay.
From the information given,
P = $22000
r = 10.5% = 10.5/100 = 0.105
t = 5 years
Therefore
A = 22000(1 - 0.105)^5
A = 22000(0.895)^5
A = $12634
Answer:
3526
Step-by-step explanation:
4300×3%=129
129×6=774
4300_774= 3526
