Answer:
The final amount is 550.93.
Step-by-step explanation:
Here, the given amount is 468.
Now 8% of the given amount is 
⇒ 8% of 468 = 37.44
So, the New amount = Initial Amount + 8% increase
= 468. + 37.44 = 505.44
Now 9 % of the new amount 505.44 is
[tex]\frac{9}{100} \times 505.44 = 45.4896/tex]
⇒ 9% of 505.44 = 45.4896
So, the Final amount = New Amount + 9% increase
= 505.44 + 45.4896 = 550.93
Hence, final amount is 550.93.
Answer:
408
Step-by-step explanation:
Volume = length times width times height
So in this situation we can see that 17 is the length, 8 is the width, and 6 is the height
Knowing this information we can continue
If you think of a regular cube, you can split it diagonally and then it would be 2 triangles
So we can split the width, in halve which would be 4 and then apply the formula 4*6*17 and when you solve that you get 408 Now we have to split that in halve because remember it is a triangle and a triangle is halve of a square. Halve of 408 is 204.
If we repeat that prosses for the other side we will also get 204. Now we add 204+204 to get our answer 408.
Sorry is this was a little confusing but that's the best I can explain it.
Hope that helped and have a great day!

Answer:
(C) Step 1: 15x − 20 = 1; Step 2: 15x = 21
Step-by-step explanation:
The first step is to eliminate the parentheses, using the distributive property.
5(3x − 4) = 1
15x -20 = 1
The second step is to add 20 to both sides of the equation.
15x = 21
This pair of steps is shown in the 3rd choice.

<em>Comment on the answers</em>
The distributive property seems to be applied incorrectly a lot of the time. Here, you can choose the correct answer by looking at the result of properly applying the distributive property: 5(3x-4) = 15x-20. Only the correct choice has this as the first step.
