Huh? that is difficult I have no idea
Answer:
U= 60
Step-by-step explanation:
it is 60 because they are opposite but they = each other. also if u want proof (the long way) then u do subtract the degree of the line which is 180. so 180-60 = 120 for the first line. so the angle next to the 60 is 120, now u do 180-120=60 and thats = to u
Answer: For 1, the answer is B since there is no rational number for sqrt17.
For 2, the answer is C since it has to be less than 11 whose square is 121 and larger than 10 whose squre is 100.
For 3 the answer is B. Just plug the x value into the equation. => y=1/2(-1)-2 => y= -1/2-2 => -2 1/2.
For 4 the answer is A because the graph first goes up then stys their staticly for a while then plumets down. It fits the description of the first one.
Step-by-step explanation:
Have a nice day, I hope next time you can solve it yourself! :D
Let's solve your problem:
The answer would be 280%.
We know the following information:
2pm - 15 toilet paper rolls
5pm - 57 toilet paper rolls
We have to find the <u>percent rate of change.</u>
Here is how we will do this problem:
<h3><u>
First, Set up a ratio:</u></h3>
Change in the quantity [15 - 57]
-------------------------------------
Original quantity [15]
57 - 15 = 42
<h3><u>
Next, we will divide. the ratio.</u></h3>
Given quantity - 42
Number of packs sold at 2pm - 15
Fraction - 42/15
<h3><u>
Convert the fraction to a decimal.</u></h3>
Fraction - 42/15
Decimal - 2.8
<h3>
<u>Make the decimal to a percent.</u></h3>
Decimal - 2.8
Percent - 28%
<u>Add a zero to the 28.</u>
<h2><u>
Our answer is 280%</u></h2>
