Answer: There are 152 apples.
The explanation is shown below:
- You need to write the following three equations, where is the the number of apples, is the number of pears and is the number of oranges:
1)
2)
3)
- You must substitute the equation 3) into the equation 2):
- Now, you need to solve for in the equation 1) and then you must substitute it into :
- Solve for , as following:
- Therefore, there are 152 apples.
10^2+8^2-7^2/(2*10*8)
= 115/160 = 0.71875 round off to 0.72
So, if the angle 16 is equal to 139; by knowing that angles opposite the vertex have equal measure, since they have equal amplitude, we can conclude that angle m4 is equal to:
Expression for percent of survey participants who chose fishing =
Explanation:
Total number of boys = 60
Number of boys who took part in survey = 18 + 29 =47
Number of boys who chose fishing = 29.
Percentage of an outcome = (Number of favorable outcome/ Total number of outcome) x 100
Percentage of boys who chose fishing = (29/47)x100
Expression for percent of survey participants who chose fishing =
