Answer:
It will take Naomi 22 hours
Step-by-step explanation:
If they work together Mark, Naomi, and Yvonne take 11 hours, which means
three people represent 3* 11 = 33 man* hours
If they work alone Yvonne will take 5 man hours, and Mark will take 6* man hours.
Now we know that together they take 33 man hours therefore we have
5+ 6+ N = 33
Where N is Naomi's man* hours. We solve for N and get:
N = 33 - 11 = 22
N = 22
Naomi will take 22 hours to finish the job if she worked alone.
Answer:
no!!
Step-by-step explanation:
it's b!! simply solve for y by subtracting both sides by 3x and then dividing both sides by 2
the fraction 8/1 because when dividing fractions you want to flip the second fraction aka 8/1 and multiply the two together.
ex:
3 ÷ 8/1
3/1 × 1/8
answer- 3/24
hope this helps bb ♡
Answer:
(14, 2 )
Step-by-step explanation:
Use the midpoint formula
[0.5(x₁ + x₂), 0.5(y₁ + y₂) ]
with (x₁, y₁ ) = (16, 7) and (x₂, y₂ ) = (12, - 3)
midpoint = [0.5(16 + 12), 0.5(7 - 3) ] = [0.5(28), 0.5(4) ] = (14, 2 )
The answer is 7 ^39 in the field.
Please correct me if I'm wrong!! :)
