S(t) = 3.82 - 0.2t
Step-by-step explanation:
After 7 weeks, the ice is 2.42 meters thick. The ice loses 0.2 meters of thickness per week; this means on the 7th week, it has lost 7(0.2) = 1.4 meters of thickness.
This means the ice started at 2.42+1.4 = 3.82 meters thick.
Our function will start at the original thickness of the ice, 3.82 meters.
Since the ice is losing thickness, we will subtract; it loses at a rate of 0.2 meters per week (t), which gives us 0.2t. This is subtracted from the original, 3.82 meters, giving us
S(t) = 3.82 - 0.2t
$1100 because 12% of 500 is $60 x 10 is $600 + 500
Answer:
12/7=x
Hope this helps :)
Step-by-step explanation:
1. subtract 7 from both sides of the equation.
2.Simplify.
3. Divide both sides of the equation by the same term.
4.Simplify.
Answer:k=3
Step-by-step explanation:
Parece que faltan datos
para poder hallar el valor de la incognita k. Debe haber una ecuación
Suponiendo que tu expresion estaba igualada a cero
-4k+12=0
Despejando k quedaría -4k=-12
luego k=(-12)/(-4)
obteniendo el valor de k=3 positivo
Answer:
10.6% decrease
Step-by-step explanation:
The percentage change in a quantity is computed using ...
percentage change = ((new value)/(old value) -1) × 100%
= (2.10/2.35 -1) × 100%
= (0.8936 -1) × 100%
= -.1064 × 100%
= -10.64%
The percentage decrease was about 10.6%.
