Answer:
11
Step-by-step explanation:
6.6/0.6 = 66/6 = 11
Answer:
12 years = 16 USD
15 years = 20 USD
Step-by-step explanation:
15 years =72:4= 18 we round to 20 for 15 years
12 years = 20+20 = 40
72-40 = 32 : 2 = 16 USD for 12 years
3/2 - x = -12
(multiply everything by 2 to get rid of fraction)
3-2x= -24
3+24 = 2x
3/2 + 12 = x
X= width
length= 3x-7
Area: (x)(3x-7)=40
= 3x^2-7x=40
= 3x^2-7x-40=0
Factorise the equation: (3x+8)(x-5)=0
x=-8/3 (reject because width cannot be negative) or x=5
so width is 5cm and length is 3(5)-7= 8cm !
T = 2π√(l/g)

<span>=> T ≈ 4,49s </span>
