Green, because purple and green have 3 cubes so they both have the same probability of being chosen

Step-by-step explanation:
<u>Given:</u>
2/20 : 1/40
A). First re-write the ratio as follows;
(i) Change the ratio sign to division (÷). i.e
2/20 ÷ 1/40
(ii) Solve the expression by changing the division to multiplication(×). This also means you will need to swap the numerator and the denominator of the second term. i.e (1 / 40) becomes (40 / 1)
(2/20) × (40 / 1) = × =
B). Now convert the result from above to unit rate. A unit rate is a rate in which the denominator has a value of 1.
So to convert to unit rate, we keep simplifying until the denominator becomes 1.
And since the denominator is already 1, there is no need for further simplification.
Therefore, 2/20 : 1/40 to unit rate is
It is given in the question that your computer monitor has a width of 14.98 inches and a height of 11.24 inches.
And we have to find the area of the monitor display in square meters.
And the formula of area is width times height .
SO to find the area, we have to multiply the given width and height.That is
And now we need to convert square inches to square meters and for that we have to multiply the given answer by 0.00064516. That is
Step-by-step explanation:
Volume= [(20+20) x (20+20) x 100] - (20 x 20 x 100)
=120000cm^3
surface area= 2 x 40 x 100 + 2 x (40 x 40 - 20 x 20) + 4 x 20 x 100
=18400cm^2
