It is thirteen because you have to add to 6 till you get eleven and you go up 8 more and then you subtract it all and get your answer
Answer:
55/28 hours/day (approx. 1.96 hours/day)
Step-by-step explanation:
9 1/6 hours / 4 2/3 days
= 55/6 hours / 14/3 days
= 55/6 * 3/14 hours/day
= 55/28 hours/day
(approx. 1.96 hours/day)
Answer:
This would be a decay function.
Step-by-step explanation:
When a function is a growth function that means that it is growing but a decay function means that it is getting smaller.
Answer:
y = 12
Step-by-step explanation:
Complementary angles sum to 90 , so
3y - 1 + 4y + 7 = 90
7y + 6 = 90 ( subtract 6 from both sides )
7y = 84 ( divide both sides by 7 )
y = 12
For number 15 and 16, you just have to find the absolute difference between the two points along the calibration of the protractor.
15. ∠BXC = |B - C| = |140° - 110°| = 30°
16. ∠BXE = |B - E| = |140° - 30°| = 110°
For numbers 20 and 21, apply the Angle Addition Postulate. This is when you add the individual interior angles to equate to the total angle.
20. ∠PQS = ∠PQR + ∠RQS
112° = 72°+ 10x°
x = 4
21. ∠KLM = ∠KLN + ∠NLM
135° = 47°+ 16y°
y = 5.5
