Answer:
30.25
Step-by-step explanation:
All angles of a line must add up to 180. Since we already know that one angle is 90 degrees, we know that the other angles should add up to 90 degrees in order for all of the angles to add up to 180 degrees:
(3x-7)+(x+8)=90
4x+1=90
4x=89
x=22.25
22.25+8= 30.25
Answer: 11. Is A
Step-by-step explanation:
Look kid, this question has been up for 16 hours think its time to let it go......... hoped i helped. ✔verified✔
H (x) = b - 9/x
At (-6 , 19) ,
h (x) = 19 , x = -6 ,
19 = b - (9/-6)
19 = b + 3/2
b = 35/2
A. Range=highest-lowest. 85-53=32
b. Mean=average. Add all of the numbers together then divide by 12, you get about 70.2
c. Median is the middle number, or average of middle 2 numbers. average of 63 and 70 is 66.5.
d. There are 5 months with temperature less than 70, so the chance is 5/12
