I=prt. Sub in what you know: 562.50=1500(r)(5). Multiply: 562.5=7500r. Divide to get the unknown by itself: .075=r or 10%=r. :)
Y=-1/2x+3 is the slope intercept form.
Answer:
D. 270 cm2
Step-by-step explanation:
2*(15*5 + 15*3 + 5*3) = 270 cm2
Answer:
Step-by-step explanation:
The main part of the song is the end. The beginning length is based on the end and so is the middle length. The beginning length is 1/6 as long as the end, so if the end is our main unknown, x, the beginning is 1/6x. The middle is one-half as long as the end, so if the end is our main unknown, x, the middle is 1/2x. The sum of the 3 parts is 370, so:

The GCF of those denominators is 6, so multiply through every term by 6 to get rid of the fractions:

Simplifying gives us
6x + x + 3x = 2220 and
10x = 2220 so
x = 222
That means that the end is 222 seconds, the bginning is 37 seconds, and the middle is 111 seconds.
