Barry found a computer at Staples for $989. A week later, the computer went on sale for $849. The percentage change is 14.156 % decrease

Solution:

Given that Barry found a computer at Staples for $989

A week later, the computer went on sale for $849

To find: percent of change

Percent change is the extent to which a variable gains or loses value. The figures are arrived at by comparing the initial (or before) and final (or after) quantities according to a specific formula.

THE PERCENT CHANGE IS GIVEN AS:

$\text{ percent change } =\frac{\text { final value - initial value }}{\text { initial value }} \times 100$

If the result is positive, it is percentage increase

If the result is negative, it is percentage decrease

Here initial value = 989 and final value = 849

Substituting the values in above formula,

$\begin{aligned}&\text { percent change }=\frac{849-989}{989} \times 100\\\\&\text { percent change }=-0.14155 \times 100=-14.156 \%\end{aligned}$

Here negative sign denotes percentage decrease

Thus percentage change is 14.156 % decrease

Please help! This is grade 5 work

tatuchka [14]

Answer:

1)

7 X 8 = 56

6 X 8 = 48

8 X 8 = 64

8 X 11 = 88

8 X 16 = 128

2)

If the division is left divided goes into the right then it would be:

72 divided by 3 = 24

17 divided by 3 = 5.66666

11 divided by 3 = 3.66666

9 divided by 3 = 3

216 divided by 3 = 72

If the division is right divided goes into the left then it would be:

24 divided by 3 = 8

33 divided by 3 = 11

51 divided by 3 = 51

27 divided by 3 = 9

72 divided by 3 = 24.

Step-by-step explanation:

for the first problem you multiply the left numbers by the 8 to get the right numbers and to get the left numbers you divide the right numbers by 8.

For the second problem if the division is left divided goes into the right then it would be for getting the left numbers multiply the right numbers by 3 and for getting the right numbers just divide the left by 3 but if the division is right divided goes into the left then it would be the exact same process as before but in this one if you are getting the left numbers just divide the right by and if you getting the right numbers then multiply the left numbers by 3.

ps: sorry this answer is long.

I need help what is 1/3+1/3+1/4-1/3=?

MrRissso [65]

Answer: 7/12

Step-by-step explanation:

1/3 + 1/3 = 2/3

2/3 - 1/3 = 1/3 (Rearrange the denominator together)

= 1/3 + 1/4

(Multiple 1/3 by 4 for the numerator and the denominator)

(Multiply 1/4 by 3 for the numerator and the denominator as well)

= 4 + 3 / 12

=7/12
