The mean reflects the best measure of the center
Answer:
See Explanation
Step-by-step explanation:
The question has unclear information.
So, I'll answer from scratch
Given
ABC = Right angled triangle
DB bisects ABC
Required
Prove that CBD = 45
From the question, we have that:
ABC is right angled at B
So, when DB bisects ABC, it means that DB divides ABC into two equal angles.
i.e.

and

Substitute CBD for ABD in 


Divide both sides by 2



Hence, it is proved that

Answer:
Concert ticket now costs $79.
Step-by-step explanation:
21% is being removed from the original cost, in this case, that's $21. 100-21=79. Hope this helps ;)
Step-by-step explanation:
I think its 85in as the area.
To convert celsius to Fahrenheit:
=》(0°C × 9/5) + 32 = 32°F
To convert Fahrenheit to celsius:
=》(32°F − 32) × 5/9 = 0°C
To convert kelvin to celsius:
=》 C = K - 273.15.
To convert Fahrenheit to kelvin :
=》°F = (K − 273.15) × 9/5 + 32.
Using these formulas,
1) 38°C
= (38°C × 9/5) + 32
= 100.4°F
2) 313 K
= 313K − 273.15
= 39.85°C
3) 85°F - 69°F
= 16° F ------> difference
In celsius :
= (16°F − 32) × 5/9 =
-8.889°C
4) At 3 p.m = 13°F
If temperature increases by 2°F,
At 5 p.m =》
13 + 4
= 17°F
5) 55°F - 5
= 50°F
In kelvin :
(50°F − 32) × 5/9 + 273.15
= 283.15K
