Answer: The first step to solving this equation would be to use the distributive property to execute the parentheses.
Answer:
I make it 6 cm diameter (well....5.97 cm really, but it depends how many places you take π to!).
Explanation:
You have been given density (d) and mass (m), so first you can determine volume (v).
<span>d=<span>m/v</span></span> therefore <span>v=<span>m/d</span></span> = <span>3000/2.33</span> = 1287.55 <span>c<span>m^3</span></span>
Now you have the volume and the length (L) from which you can work out the cross sectional area, <span>π.<span>r2</span></span>, and from that the diameter.
Volume v =<span>π.<span>r2</span>.L</span> therefore r = <span>√<span>v/<span>π.L</span></span></span> and diameter D = 2r = <span>√(<span>v<span>π.L)</span></span></span>x 2.
So plugging in the numbers gives: D = <span>√(<span>1287.55/<span>3.142X46)</span></span></span> X2 = 5.97 cm.
Answer:
B is the correct graph
i dont know how to explain tho :/
Answer:
21 = 21
Step-by-step explanation:
5x + 1 = 21
-1 -1
5x = 20
__ __
5 5
x = 4
5x + 1 = 21 First substitute x for 4
5(4) + 1 = 21 Then continue to solve the problem to get the proof
20 + 1 = 21
21 = 21
