Answer:
(1, 14)
Step-by-step explanation:
If you substitute the 14 in;
14 = 12x+2
-2 -2
12 = 12x
/12 /12
1 = x
A scale of 1:40 can be read as "one cm on the model corresponds to 40 cm in the original object". or
"one inch on the model corresponds to 40 inches
this means that the 2 inches correspond to 2 times 40, that is 80 inches and 1.5 corresponds to 1.5*40=60 inches
which means that the original painting has dimensions of 80 by 60 inches.
b) Area = 80 cm * 60 cm = 4,800 cm²
c) 80 cm * 1 inch / 2.54 cm = 31.50 inches ;
60 cm * 1 inch/2.54 cm = 23.60 inches
d) Area = 31.50 in * 23.60 in = 743.40 inches²
Answer: 7 people need 16 minutes to paint 4 walls.
Step-by-step explanation:
Since we have given that it takes 63 minutes to paint 9 walls ,
So, we will apply "time and work formula" i.e.
where,
H denotes number of hours or minutes,
D denotes number of days
M denotes number of men
W denotes work done them,
So, we need to calculate number of minutes for 7 people to paint 4 walls,
So, 7 people need 16 minutes to paint 4 walls.
As far as I can see you have gotten the majority of them right.
The only one I see, is the last number on the 4th row from the bottom.
