Answer:
127 3/4
Step-by-step explanation:
you are just dividing the previous term by 2.
4th: 16 / 2 = 8
5th: 8 / 2 = 4
6th: 4 / 2 = 2
7th: 2 / 2 = 1
8th: 1 / 2 = 1/2
9th: 1/2 / 2 = 1/4
Add in groups of three to make it easier.
64 + 32 + 16 = 112
8 + 4 + 2 = 14
1 + 1/2 + 1/4 = 3/2 + 1/4 = 1 3/4
112 + 14 + 7/4 = 127 3/4
Answer:
The correct answer here is A. x = 17.
How I found this out:
3x + 3 and 5x - 7 are going to be different solutions in the end.
I did the process of elimination.
First, I subsituted, 17 for x. 3 X 17 + 3 = 54. 5 X 17 - 7 = 78.
I then took 180 - 54 - 48 = 78 and 180 - 78 - 48 = 54, just to make sure they are positive numbers and not negative.
Since they work out, I chose this as my correct answer to your question.
Step-by-step explanation:
Hope this helps! :)
I tried my best so I'm it's wrong.
Answer:
An equation that could be used to represent this equation is:
y = 2.5x - 2.5
Step-by-step explanation:
x = number of hours
y = the amount that the user has to pay
You have to multiply the number of hours by $2.50. Then subtract $2.50 from that amount for the first hour that is the parking garage allows the user to park for free.
Answer:
91.7 inches to 1 decimal place
Step-by-step explanation:
We will use Pythagoras's theorem to find the height of the pyramid.
The height of the Pyramid forms a right-angled triangle with half of the base and the slant height.
We can get half the length of the base by dividing the length of one side of the base = 20.4 by 2 = 10.2in
slant height = 92.3in
Therefore height = ![\sqrt{92.3^{2} -10.2^2} =91.73in](https://tex.z-dn.net/?f=%5Csqrt%7B92.3%5E%7B2%7D%20-10.2%5E2%7D%20%3D91.73in)
The height of the pyramid is 91.73inches to 1 decimal place
