The answer is to it is 27
By hypothesis, we know that one song costs $1.29
If they sold 2000 songs in one day, they made 2000 * 1.29 = 2580
So they made $2580 by selling 2000 songs.
Hope this helps! :)
Answer:
Perimeter = 63.9 cm.
Area = 166.96 cm^2 to the nearest hundredth.
Step-by-step explanation:
The perimeter = 16+20.9+27 = 63.9 cm.
To find the area you can use Heron's Formula.
Area = √ [ s(s-a)(s-b)(s-c)] where s = the semi-perimeter and a, b and c are the lengths of the 3 sides.
s = 63.9 / 2 = 31.95.
Area of the triangle = √ (31.95(31.95-16)(31.95-20.9)(31.95-27)]
= 166.96 cm^2.
Let's set the population of Zimbabwe in 1950 equal to x.
So in 2003, the population was 12.6 million. So our equation should equal 12.6 million. Here's how you turn the other parts of the problem into an equation:
4x + 1m = 12.6 m
Now to solve.
4x = 12.6m - 1m
4x = 11.6m
x = 11.6m/4
x = 2.9m
In 1950, the population was 2.9 million
The answer is the first one. You know because -4x x 5 is -20x and this option is the only one with -20x included.
