Answer: x=15
Answer: x=15
.......
V pyramid = (1/3)*B*h where B is the area of the base
V = (1/3) * 12 * 16 * 7
V = 448 m^3
Answer:
x=12.22
Step-by-step explanation:
Sin(70)=13/x
xsin(70)=13
x=sin(70)13
x=12.22
No, not at all.
The general quadratic equation is
Ax² + Bx + C = 0 .
The roots are real only if (B² - 4AC) is not negative.
That means if you graph it, it touches or crosses the x-axis.
If the graph is up in the air and never touches the x-axis,
then it has no real roots.
Let s be standard and h be high-quality versions of the song.
To figure this out, let's make a system of equations:
2.5s + 4.5h = 5740
h = 4s
First substitute the second equation into the first for h.
2.5s + 18s =5740
Then combine like terms.
20.5s = 5740
Lastly, divide each side by 20.5 to get the number of standard downloads:
s = 280
Hope this helps!
