Answer:
Step-by-step explanation:
All you have to do for this is follow PEMDAS (Parenthesis, Exponent, Multiplication, Division, Addition, Substraction) Which is the order of operations.
First you do parenthesis, , when you have a positive exponent outside a parenthesis like this, you add them together, and in this case, you get,
After that, you do the rest of the exponents as well as multiplication, .
Now we plug in the 81 from our last step along with the 16 from the first step and multiply them together.
Then you just simply need to find which of the answers come out to be the result we got which is 1296. Out of these 4 possible answers, ends up being equal to 1296 which means that is the correct answer.
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:
A = 24 m^2
The unit is m^2
Step-by-step explanation:
The area of the rectangle is found by using the formula
A = l*w
where l is the length and w = width
A = 3m * 8 m
A = 24 m^2
The unit is m^2
Answer:
Simple!
Step-by-step explanation:
14 + 19 + 18 + 12 + 22 + 15 + 16 + 16 + 14 + 14 + 21 + 20 = 201 divided by 12 = 16.75! HOPE THIS HELPS! !!
