Answer: 2/3 hours
Step-by-step explanation: 1 1/3 will equal 4/3 as you have a whole number equaling 3/1 so then you divide by two and get 2/3
Answer:
The last one.
Step-by-step explanation:
30 is colder than 80, so it holds less heat/thermal energy.
Step-by-step explanation:
<AOF and <COD are vertical angles.
m<AOF = m<COD = 80°
Angle Addition Postulate m<BOF - m<AOF = m<AOB
m<AOB = 135° - 80° = 55°
Basically you set it up 43/8+26/5. When you do that multiply 5 by 8 so the donominiter will be 40. Then multiply 5 by 43 which is 215 and 8 by 26 which is 208 so now you have the same donominiter... 215/40+208/40 add 215 to 208 that's 423/40 then you see how many times does 40 divide into 423 that's 10 and then you had 23 left so put 10 23/4 .if it was a case like 10 3/12 you could simplify it and that would be 10 1/4 ...
Answer:
80
Step-by-step explanation:
sum of angles at a point = 360
85+2x+x+35=360
3x+120=360
3x=360-120
3x=240
x=240/3
x=80⁰
