Answer:
22.6875 or 22.69
Step-by-step explanation:
When adding up fractions, you need to first either turn them into a decimal or a fraction with the same denominator. I'm going to go with the decimal one. You would divide 1 into 4 which gives you. 25. Now you have 12.25. Next you divide 7 into 16 which gives you .4375 but you can round this up if you need to. You now have 10.4375. Finally you need to add them together to get 22.6875.
69/100 kilometers
you want to make the denominator for both numbers and to do that you would multiply 5/10 by 10 and you would get 50/100 and 50/100+19/100 which equals 69/100
Answer:

Step-by-step explanation:
We begin with the equation
for which we need to solve for a.
The first thing that we can do is to factor out the a from both terms on the left side of the equation

Then we can divide each side by
to isolate a

Answer: The parabola has its concavity downwards, so we need a function in the model:
With a negative value of 'a'
The vertex is (0,0), so we have that:
The x-coordinate of the vertex is given by the equation:
So we have a function in the model:
With a < 0
The only option with this format is B:
