Combined rates

Susan = 2 car / 3 hr
= 2/3

Joe = 3 car / 4 hr
= 3/4

add the rates to get the new combined rate as 17 cars in "t" hours.

2/3 + 3/4 = 17/t

Need common denominator

2/3(4/4) + 3/4(3/3) = 17/t

8/12 + 9/12 = 17/t

17/12 = 17/t

see that "t" is 12 hours

£11000 of 3.9% compound interest of 3 years ?
FinnZ [79.3K]
Compound Interest

A = P(1 + r)^(n)

A = Amount, r = rate per year = 3.9% = 3.9/100 = 0.039, n = year = 3 

A = P(1 + r)^(n)

A = 11000(1 + 0.039)^(3)

A = 11000(1.039)^(3)      use calculator

A ≈ 12337.85

Compound Interest = A - P = 12337.85 - 11000 = 1337.85

So at the end of 3 years the Amount is ≈ £12 337.85 and the compound interest is ≈ £1 337.85 

Hope this helps.

PLEASE HELP
Colt1911 [192]

Answer:

B.In slope-intercept form, the slope is −79.These values are A and B, but with the opposite sign, so the slope of the line from the equation in standard form is −AB.

Step-by-step explanation:

A is being moved to the other side of the equation so it has to be negative and is multiplied by B since the y value has to be divided to equal the base of y not 9y but y.
