This is the concept of proportionality, we are required to calculate for the number of hours two crews can use to paint the house altogether.
Here proceed as follows;
number of hours new crew can paint=12 hrs
portion of work painted by new crew in 1 hour= 1/12
number of hours experienced crew can paint=6 hours
Portion of work painted by experienced crew in 1 hour=1/6
Portion of work painted by the two crews altogether in 1 hour will be:
1/6+1/12=1/4
thus the total amount of hours that the two painters will take to paint will be:
4 hours
Answer:
<h2>
10 units</h2>
Option C is the correct option
Step-by-step explanation:
Let the points be A and B
A ( 4 , 5 ) ------> ( x1 , y1 )
B ( 10 , 13 ) ------> ( x2 , y2 )
Now, let's find the distance between these points:
plug the values
Calculate the difference
Evaluate the power
Add the numbers
Write the number in exponential form with. base of 10
Reduce the index of the radical and exponent with 2
Hope this helps..
Best regards!!
hopefully someone helps u with this tho sorry
Answer:
44
Step-by-step explanation:
there you goooooo oooooooooooooooooo
Since it's a multiple of 24, it has to be a multiple of the factors of 24.
Factors of 24:
2,3,4,6,8,12
You can use some of this knowledge to help create the number.
Since the # needs to be a multiple off 2, the last digit needs to be an 8
All numbers that are multiples of 3 have the property that all of their digits added together have to be a number that is evenly divisible by 3.
so your number will look like:
_ _ _ _ _ 8
so start trying combinations for the other 5 digits that give you a number that is a multiple of 3: 3,6,9,12,15, ect. If you can't find one, then it's impossible
