Answer:
23 apples
Step-by-step explanation:
1/8 of 40 = 5, 20 percent of 40 is 8. 8+4+5 = 17. 40-17 is 23
Answer:
4:2:3
Step-by-step explanation:
16 blue marbles,8 green marbles and 12 red marbles.
Ratio of blue to green to red
blue:green:red
16:8:12
We can divide each term by 4
16/4:8/4:12/4
4:2:3
Let the answer be x.
Hence, f = x is the answer.
<h2><u>
Solution</u>
:</h2>
<em>To find the zero,</em>
<em>x</em> + 1 - 4 = 0
<em>x</em> = 4 - 1
<em>x</em> = 3
3 is the <u>root</u> of <em>(x + 1) - 4</em>.
So a general harmonic equation is Asin(2πt/T). Little t is just a variable. 6 inches is the height of one maximum and one minimum from equilibrium, so that is the amplitude A. T is the period, or the time of one cycle (or wavelength), which is 2 seconds.
The equation is therefore (in terms of seconds and inches), 6*sin(2πt/2), or 6*sin(πt).
