Eight days = _ hours<br> Please tell me
Lana71 [14]
In order to answer this question, you need to know how many hours
there are in one day.  After that, it's a piece-o-cake.

                       1 day  =  24 hours .

Now you can make a table:

1 day  =  24 hours
2 days = 48 hours
3 days = 72 hours
4 days = 96 hours
5 days = 120 hours
6 days = 144 hours
7 days = 168 hours
8 days = 192 hours
9 days = 216 hours
10 days = 240 hours

Ivenika [448]
This would vary on the perspective of the solver. In this case, the solution would be

                A     A     A     B     B     B     B     C     C     C
 
                A     A     A     B     B     B     B     C     C     C
 
                A     A     A     B     B     B     B     C     C     C
              
                A     A     A     B     B     B     B     C     C     C
 
                A     A     A     B     B     B     B     C     C     C
 
                A     A     A     B     B     B     B     C     C     C

                A     A     A     B     B     B     B     C     C     C
 
                A     A     A     B     B     B     B     C     C     C

such that Employee A would constitute 30%, Employee B would constitute 40% and Employee C would constitute 30% of the work.

Solve the equation.<br> 3+ 4.5(2d – 3) = 7.5
Scorpion4ik [409]

Answer:

d=2

Step-by-step explanation:

Let's solve your equation step-by-step.

3+4.5(2d−3)=7.5

Step 1: Simplify both sides of the equation.

3+4.5(2d−3)=7.5

3+(4.5)(2d)+(4.5)(−3)=7.5(Distribute)

3+9d+−13.5=7.5

(9d)+(3+−13.5)=7.5(Combine Like Terms)

9d+−10.5=7.5

9d−10.5=7.5

Step 2: Add 10.5 to both sides.

9d−10.5+10.5=7.5+10.5

9d=18

Step 3: Divide both sides by 9.

9d

9

=

18

9

d=2

d=2
