Answer:

12.5 % decrease

Step-by-step explanation:

To find the percent loss

Take the original amount and subtract the new amount

2.4 -2.1 = .3

Divide by the original amount

.3/2.4 = .125

Multiply by 100 to change to a percent

12.5 %

This is the percent decrease

Answer:

$x^6+3x^3+3+\dfrac{1}{x^3}$

Step-by-step explanation:

We can use the pascal triangle to find the coefficients of the expasion of the cube. It holds that

$(x^2 + \dfrac{1}{x})^3=(x^2)^3+3(x^2)^2\dfrac{1}{x}+3x^2(\dfrac{1}{x})^2+(\dfrac{1}{x})^3\\\\=x^6+3x^4\dfrac{1}{x}+3x^2\dfrac{1}{x^2}+\dfrac{1}{x^3}\\\\=x^6+3x^3+3+\dfrac{1}{x^3}$

Answer:

A) 46 mph

Step-by-step explanation:

Step 1: To find the speed, you need to find the distance and time to travel between Chicago and Cleveland.

Distance = 354 miles

Time = 9: 50 am to 5: 30 pm

Time = 7 hours 40 minutes

Step 2: Convert time to hours

1 hour = 60 minutes

40 minutes = 60/40 = 2/3 hours

Step 3: Find the speed

Speed = Distance/Time

Speed = 354/7 + 2/3

Speed = 1062/23

Speed = 46.17 miles per hour rounded off to 46 mph

Therefore, A is the correct answer.
