Answer:
commutative property of multiplication
Step-by-step explanation:
The commutative property of multiplication is correct. The commutative property of multiplication is basically arranging the numbers in any way and it won't change the product.
The associative property of multiplication is arranging the numbers in parenthesis and it won't change the product either.
we are given
-3 x 2(4-18) + 8 =
Firstly , we will solve inside parenthesis
now, we can multiply
............Answer
Start with the exponents, 3 and -2, you multiply them together so you get -6 so its w(w^-6)/w^-4 and then you do wx5w^-6 which is 5w^-4 bc im pretty sure you multiply it to 5w and thats 5w squared so you just add it and so it becomes 5w^-4/5w^-4 and you can simplify that
% error = {|Approximate Value - Exact Value| ÷ |Exact Value|} * 100%
The difference of the Approximate and the Exact Value is an absolute value. Therefore, the negative sign of the difference is disregarded.
1) Estimate = 250 g ; Actual = 240 g
(250 - 240)/240 * 100% = 10/240 * 100% = 4.17%
2) Estimate = 97.5°C ; Actual = 100°C
(97.5 - 100)/100 * 100% = |-2.5|/100 * 100/% = 2.5%
3) Estimate = 10.4 ml ; Actual = 9.7 ml
(10.4 - 9.7)/9.7 * 100% = 0.7/9.7 * 100% = 7.22%
4) Estimate = 0.156 cal/g°C ; Actual = 0.185 cal/g°C
(0.156-0.185)/0.185 * 100% = |-0.029|/0.185 * 100% = 15.68%
5) Estimate = 62.5 g ; Actual = 65.2 g
(62.50 - 65.20)/65.20 * 100% = |-2.7|/65.20 * 100% = 4.14%
