Well what +8 will be -11.
Let’s take this as positives.
8+11=19
Sooo
-19+8=-11
C=-19
for these kinds of problems the outside angle always equals the opposite 2. meaning angle x=64+70 which is 134 degrees. you can double check this because all triangles equal 180 degrees. meaning that the last angle in the triangle is 46. 46+70+64=180.
so your answer is 134.
hope this helps :)
Answer:
![a = 2 , f(2)=9](https://tex.z-dn.net/?f=%20a%20%3D%202%20%2C%20f%282%29%3D9)
![b = 4 , f(4)=64](https://tex.z-dn.net/?f=%20b%20%3D%204%20%2C%20f%284%29%3D64)
And replacing the data into the average rate formula we got:
![m = \frac{64-9}{4-2}= 27.5](https://tex.z-dn.net/?f=%20m%20%3D%20%5Cfrac%7B64-9%7D%7B4-2%7D%3D%2027.5)
And then the best answer for this case would be:
C. 27.5
Step-by-step explanation:
For this cae we know that the average rate of change of a function is given by this general expresion:
![m = \frac{f(b) -f(a)}{b-a}](https://tex.z-dn.net/?f=%20m%20%3D%20%5Cfrac%7Bf%28b%29%20-f%28a%29%7D%7Bb-a%7D)
For this special case from the info of the table we have:
![a = 2 , f(2)=9](https://tex.z-dn.net/?f=%20a%20%3D%202%20%2C%20f%282%29%3D9)
![b = 4 , f(4)=64](https://tex.z-dn.net/?f=%20b%20%3D%204%20%2C%20f%284%29%3D64)
And replacing the data into the average rate formula we got:
![m = \frac{64-9}{4-2}= 27.5](https://tex.z-dn.net/?f=%20m%20%3D%20%5Cfrac%7B64-9%7D%7B4-2%7D%3D%2027.5)
And then the best answer for this case would be:
C. 27.5
Answer:
Step-by-step explanation:
1. Write an expression to show how to calculate the number of buses needed. Make sure to include parenthesis to show what should be done first since order of operations is important.
(9*25)+4+(2*4)=237 (total number of people going to the museum
Each bus,excluding the driver,holds 44 people
237/44 = 5.3863636363.......
2. How many buses will be needed?
6 buses are needed
3. Why must the answer to the problem be a whole number?
Buses cannot be divided in fractions It should be or 5 buse or 6
But 5 buses are not enough
4. Why shouldn't you round the answer the usual way?
Even when rounded it is still a decimal and buses need to be counted by whole number
5. Can your answer be classified as a rational number? Explain why or why not.
6 is a rational number (whole number)
5.38636363.......is rational ( repeating decimal
