600 litres of what? Water? Oil?
You have to specifiy which kind of liquid is used, because the density differs.

2027 mod a = 7
=> 2020 mod a = 0
=> gcd(2020,a) != 1
2020 = 2^2*5*101
So we have to calculate all combinations with 2^2*5*101 (=3^2):
2*5
2*101
2*5*101
2*2*5
2*2*5*101
101
5*101
2*2*101
2*2 <- less than 7, but a must be greater than 7

Ergo: There are 8 positive integers of a so that 2027 mod a = 7

christina:
how you solve for v with equation k=1/2mv^2

First, you multiply the equation by 2/m and you obtain 2k/m=v^2. Then you take the square root: sqrt(2k/m)=v. That's all.

The initial weight is 15 tons
on the first birthday 12 month will pass
as given on each of the first 12 months the whale will gain 2.3 tons
means the whole weight gained = 12 x 2.3 = 27.6 tons
the final weight = 15 +27.6 = 42.6 tons
i hope that helped !

Ok

4y - 5 = 2y - 9

4y = 2y - 4

2y = - 4

y = - 2

-5+32=2(p-2)
Add 5 to each side and do the brackets.
27=2p-4
Add 4 to each side
31=2p
Divide each side by 2
p=31/2

4x+4=2x+8
Subtract 4 from each side
4x=2x+4
Subtract 2x from each side
2x= 4
Divide by 2
x=2

ok if u take length to be x and width to be w
length=x
width=w

width is 6ft less than length so:
w=x-6

the equation for area:
area=length.width
area=x.w
area=x.(x-6)

area is 75ft
so
75 = x(x-6)
75=x^2-6x

as a quadratic
x^2-6x-75=0
after this use the quadtractif formula to find x which is length
then subsitute it into
75=x.w
to find width

-2x^2 is the simplest form of the equation. it cant be simplified any further

Radius of a circle = square root of (area/pi). I'm assuming you refered 4.55 to area. So you have:
r = square root of (4.55/pi) = 1.2034575115625177.

Hope this helps!
