Answer:
16 per hour
Step-by-step explanation:
12/45 x/60 cross multiply
45x=720 divide by 45 from each side
x=16
This is an equation of exponential decay
y(t) = a b^ t where a is the initial amount
b is the decay factor
t is the time in years
b is found by taking 1 and subtracting the percent it decreases in decimal form
Letting t =4
y(t) = 260 million * ( 1- .011) ^ 4
=248.7473796 million
=24874737.96
Rounding to a whole number
= 24874738
Answer:
60
Step-by-step explanation:
let a = 22 / kg, and b = 12 / kg
a + b = 20 kg
22a + 12b = 15 * 20
12a + 12b = 240
10a = 60
Step-by-step explanation:
x²+7x+12
x²+4x+3x+12
x(x+4)+3(x+4)
(x+3)(x+4)
