Answer:
2.1 hours (2 hours and 6 minutes)
Step-by-step explanation:
The rate of work of Bobbi is ⅓ while for Deshaun is 1/7 hence combined rate will be
⅓+1/7=(7+3)/21=10/21
The equivalent hours is the reciprocal of the above hence 1021/10=2.1 hours
0.1 of an hour is equivalent to 0.1*60=6 minutes
Therefore, the efforts combined will take 2.1 hours or 2 hours and 6 minutes
Answer:
x = 6
Step-by-step explanation:
This shows that the angle being split is 90 degrees.
<em>We know that 32 degrees are already known so we can do </em><em>90 - 32 = 58</em>
Now we know that 58 is the angle of 9x + 4
9x + 4 = 58
Subtract 4 from both sides
9x = 54
Divide both sides by 9 to isolate x
x = 6
