Answer:
<u>The correct answer is A. The distance traveled depends on the number of hours traveled. </u>
Step-by-step explanation:
Let's recall that:
1. The formula of the speed is distance/time
2. If the speed is constant, like the train in our problem, which is 45 miles per hour, then we can assume it as a value of 1 and a we can confirm a direct relation between the distance traveled and the number of hours traveled, this way:
Speed = Distance/Time
Distance = Speed * Time
Distance = 1 * Time
Distance = Time
This means the longer you stay in the train, the more miles you will travel or the more hours you travel by the train, the more distance you will cover.
<u>The correct answer is A. The distance traveled depends on the number of hours traveled. </u>
First you want to work the discount for the TV.
$187.13*0.75=$140.3475 (this will get you the price of the TV after the discount.)
Now round the answer $140.3475 to the nearest hundredth. The new answer is $140.35. So the price of the TV after the discount is $140.35. Next use this equation to solve for the tax that would be added to the price of the discounted TV:
(t*d)+d=p
In that equation t=taxes, d=discounted TV price, and p=price total. Now input the values you know.
(0.09*140.35)+140.35=p
Multiply what is in the parentheses first.
12.6315+140.35=p
Add the two numbers together.
152.9815=p
Round the end amount to the nearest hundredth.
152.98=p
So now you know that the total price of the discounted TV after tax is added is $152.98. I hope you could understand this and it helps! :D
Hello,
2^(-8) *2 =2^(-8+1)=2^(-7)
-8+2x=12x-3
Subtract 2x from both sides
-8=10x-3
Add 3 to both sides
-5=10x
Divide both sides by 10
-5/10 = x
-1/2= x
