We know that the area is 20.
Since 20 is a small number: lets list out possible combinations of lengths and widths.
1 * 20
2 * 10
4 * 5
L = 7 + 3w
lets see which on makes sense.
L = 7 + 3w
20 = w7 + 3w^2
3w^2 + 7w -20 = 0
(3w - 10)(w - 2)
w can equal 10/3 or 2.
So the dimensions: are Width = 2 Length = 10
Answer:
19.65°
Step-by-step explanation:
Use tan when you don't have the hypotenuse.
tan(y) = opposite/adjacent
tan(y) = 5/14
y = (tan^-1)(5/14)
y = 19.65°
Step-by-step explanation:
Let F represent fruitshake and C chocolate milkshake
one fruitshake cost more 2R more than chocolate shake and
3F + 5C = R78,00
Then (78 - 6) ÷ 8 = 9
a fruitshake costs R11,00 and chocolate milkshake costs 9R,00
i dont know how to delete but this is wrong. sorry
Answer: X = 2.75
Step-by-step explanation: 2x2 = 4x-7
4 = 4x-7
11 = 4x
11 \ 4
X = 2.75
Answer:
110.4622 = 110 (as followers cannot be in decimals).
Step-by-step explanation:
Given, growth rate is 1% = 0.01.
and it is for every 12 hours.
now, f(x) = f(1 + r)^t. where f= 100 (initial followers)
r = 0.01.
t =10 (1 for every 12 hours. so, 5 days = 120 hours = 10 times)
⇒ f(x) = 100(1+0.01)¹⁰ = 110.4622 = 110 followers.
