A half of an hour is 30 minutes
40 x 36 = 1,440
42 - 36 = 6
40 x 6 = 240
1,440 + 240 = 1680
Answer : 1680
Step 1: Multiply the Principal, which is the amount borrowed, by the interest rate.
Step 2: Compute compound interest using the following formula: A= P(1+r/n)
Hope this helps u
Answer:
Step-by-step explanation:
AB/AC =1/2
(3x-4)/(2x+12)=1/2
2(3x-4) = 1(2x+12)
6x-8=2x+12
4x=20
X=5
AC/BC =3x-4/7x-2=22/33=2/3
AB/AC=3x-4/7x-2=22/33=2/3
AB/AC=3x-4/2x+12
6x-8=2x+12
You would get 4/5 still trying to work out the last mark
Answer:
415.7 mph or mph
Step-by-step explanation:
Did you make a sketch and got a right-angled triangle?
let the horizontal distance between the plane and the station be x miles
let the distance between the plane and the station be y miles
given: dx/dt = 480 mph
find: dy/dt when y = 6
y^2 = x^2 + 3^2
when y = 6
36 = x^2 + 9
x = √27
2y dy/dt = 2x dx/dt
dy/dt = (x/y)dx/dt
= √27(480)/6
= 415.7 mph or 416 mph
i think i hope this helps
