List the multiples of 3:
3, 6, 9, 12, 15, 18,21
The ones between 10 and 20 are:
12, 15, 18
The range is the difference between the highest and lowest numbers.
Range = 18 - 12 = 6
In 1975 it was 1000tons, ok, well, in 1976 it went up by 10%, how much is a 10% increase?
well, in 1976 it was 1100 tons then, and in 1977 it went down by 5% of 1100, well, if we take 1100 to be the 100%, then what is a 5% decrease?
How many groups were there
33 divided by -3 would be -11. when there is one negative sign, your answer is always negative and when both numbers are negative your answer is positive, hope this helps.
Answer:
288
Step-by-step explanation:
To simplify use the mnemonic device PEMDAS (parenthesis, exponent, multiplication, division, addition, subtraction)
First simply -6 and 13 (since they are in the parenthesis)
-11+5+6(7)^2
Now find out what 7^2 is
-11 + 5 + 6(49)
Next multiply 6 and 49 (294)
Lastly add 5 then subtract 11 from it
299-11
288
