Answer:
The school would have to give $300 and each side would be 100cm
Step-by-step explanation:
(4x - 8)cm = Side length
Solve for X
3(4x - 8) = 300
(Getting rid of the three)
(12x -24) = 300
(Getting rid of the 24)
(12x) = 324
(Getting rid of the 12)
(12x/12) = 324/12
X = 27
27 x 4
Side length = (108 - 8)
108 - 8 = 100cm
100 x 3 = 300cm (1cm = $1)
$300
Each Side would be 100cm
Answer:
The sale price of the item is $
255
Step-by-step explanation:
To determine the amount of discount (
d
) offered by the store, we calculate
15
% of the sale price. Thus:
d = 300 × 15
÷ 100
d = 3
00 × 15 ÷ 1
00 (take the 2 zeros out on both the hundred and 3 hundred)
d = 3 × 15
d = 45
If the amount of discount is known, the sale price (
s
) of the item will be the regular price minus the discount. Hence:
s = 300 − 45
s = 255
Hope this helps you! If not sorry!

Answer: A
Step-by-step explanation:
<span>Initial number of the people that belong to a certain social website is 412. It is growing at a rate of 5% every month. It means that every month the number of people is growing 1.05 times. We can calculate how many of them will there be in 9 months: 412 * 1.05^9 = 412 * 1.55 = 638.6. When we round to the nearest whole number: there will be 369 members.</span>
