Assuming that one-pint is equal to 473 ml, how many pints can be found in 3 liters?
Svetlanka [38]
Given that 1 pint is equal to 437 ml
and 1000 ml=1 liter
then
1 pint =(437/1000) liters
simplifying we get:
1 pint= 0.437 liters
thus amount of pints in 4 liters will be:
4/0.473
=8.45666586
~8.5 pints

What is -1/2(-4/5) multiplied then in simplest form?
olchik [2.2K]
-1/2(-4/5)

Multiply the numerators by each other and do the same for the denominators.
That is:
-1(-4)=4
And 2*5=10

Now we have 4/10
Divide the numerator and the denominator by 2 to get 2/5 which is the simplest form.

Hope this helped.

Question 2 The length of a rectangle is 5 yd more than twice the width, and the area of the rectangle is 63 yd2 . Find the dimen
Sedaia [141]
<span>L = 2W + 5
A = LW = 63
L = 63/W
W=63/L

L = 2W + 5
63/W = 2W + 5
63 = 2WW + 5W
2WW + 5W - 63 = 0

2WW + 5W - 63 = 0 
is already in quadratic equation form: ax^2 + bx + c = 0

use the quadratic formula to solve for two solutions:
x = ( -b +- sqrt( bb - 4ac ) ) / 2a

the two solutions are:
x = 9/2
x = -7
you cant have a negative solution for length so use the positive one

solve for length:
L=5+2(9/2)
L=5+18/2
L=5+9
L=14


W = 9/2
L = 14</span>
