Answer:
d = 69° , e = 32° , f = 79°
Step-by-step explanation:
d and 69° are vertically opposite angles and are congruent , so
d = 69°
e and 32° are vertically opposite angles and are congruent , so
e = 32°
69° , e , f lie on a straight line and sum to 180° , that is
69° + 32° + f = 180°
101° + f = 180° ( subtract 101° from both sides )
f = 79°
Answer:
The more effective way for this data set is the mean.
Step-by-step explanation:
The median required arranging the numbers in an descending-to-ascending order, and it is also preferred if the quantity of the numbers to be an odd number.
In this case, we have repeated numbers, and the quantity is even, which makes finding the median difficult.
A is 307.2
b is 6.4 min maybe just a little less
Answer:
Part A:
x+y= 95
x = y+25
Part B : 35 minutes
Part C : No
Step-by-step explanation:
Eric plays basketball and volleyball for a total of 95 minutes every day
x+y= 95
Where:
x =the number of minutes Eric plays basketball
y= the number of minutes he plays volleyball
He plays basketball for 25 minutes longer than he plays volleyball.
x = y+25
System:
x+y= 95
x = y+25
Replacing x=y+25 on the first equation:
(y+25) + y =95
Solving for Y
y+25+y =95
25+2y=95
2y=95-25
2y=70
y = 70/2
y = 35 minutes
Part C : No
if x = 35
x+y= 95
35+y =95
y= 95-35
y = 60 minutes
Replacing y=60 on the other equation:
x = y+25
35 = 60+25
35 ≠85
the value of m is 24°
Step-by-step explanation:
m+7+2m+11=90° ( being complementary angle)
3m+18°= 90°
3m =90- 18°
3m = 72
m= 72/3
m=24°
