Answer:
28° (Answer A)
Step-by-step explanation:
Note that tan t = 8/15 = 0.533
Applying the inverse tangent function, we get
t = arctan 0.533 = 0.4900 radian
Mult. this by the radian-degree conversion factor results in: 28.072°
and when rounded off to the nearest degree, the measure of angle T is 28° (Answer A)
Answer:
How long did Yumi spend picking up litter?
6 HOURS!!!!
Step-by-step explanation:
just took it on ed:)
8x51. 8x50=? 8x5=40. 40 x 10 = 400 8x50=400. 8x1=8 400+8=408.
To solve this problem we will start by calculating time needed for each of them to fill the pool.
We have formula:
Volume = rate * time
Or
time = volume / rate
Wilma:
time = 9900 / 900
time = 11h
Betty:
time = 9900 / 500
time = 19.8h
Now we substract these two numbers:
time_difference = 19.8 - 11 = 8.8h
Betty needs 8.8 hours more than Wilma to fill the pool.
