Answer:
107 :)
Step-by-step explanation:
In total there are 53+8+155+17+145+10+98+2=488 physicians of aerospace medicine. 45-54 year-old males account for 145/488 of this population, so they should account for that fraction of the central angle of the circle graph also. Since there are 360 degrees in the central angle to divide up among the groups, the 45-54 year-old male group should get 145/488 x 360 which rounds to about 107 degrees.
ANSWER
Multiply through by LCM of 15
Expand brackets to obtain,
Group like terms
In interval form it is written as
Substitue y=3x+2 to the y in y=x+10.
3x+2= x+10
Subtract 2 to both sides.
3x=x+8
Subtract x to both sides.
2x=8
Divide both sides by 2
2x/2 = 8/2
You are left with x = 4
Choose one equation and replace x by 4.
y = (4) + 10
y= 14
Now, you have x = 4 and y= 14. So, your ordered pair is (4,14) because both lines pass through that point.
If you do not want to do this solution, I suggest you graph it using the slope.
Answer:
The fraction of students who likes soccer or basketball is 7/10.
Step-by-step explanation:
In this case we have two groups of students, the group a is the one that prefers soccer, while the second group is the one that prefers basketball. We then need to find the fraction that represents the students that are in either group, in these cases we need to take the fractions of each group and sum them. So we have:
soccer OR basketball = soccer + basketball
soccer OR basketball = 2/5 + 3/10
Through LMC we have:
soccer OR basketball = (2*2 + 3)/10 = (4 + 3)/10 = 7/10
The fraction of students who likes soccer or basketball is 7/10.
Answer:
Ravi had 355ml water to begin with.
Step-by-step explanation:
Given that,
amount of water that Gwent pour in Ravi = 256 ml
amount of water that Henry pour in Ravi = 189 ml
amount of water after each have poured = 800 ml
suppose amount of water ravi had before both poured water in it = x
Equation
256 + 189 + x = 800
445 + x = 800
x = 355ml
Initially ravi had 335ml of water.
