Please at least help me with one of them cause I have no idea

Fudgin [204]

Answer:

Solving $v = \frac{4}{3}\pi r^3$ for r gives us: $r=\sqrt[3]{\frac{3v}{4\pi}}$

Solving $a_{ave} = \frac{v_2-v_1}{t_2-t_1}$ for v2 gives us: $v_2 = (t_2-t_1)a_{ave}+v_1$

Step-by-step explanation:

Solving an equation for a variable or constant means that we have to isolate the value on one side of the equation or write the whole equation in terms of that variable or constant.

Now,

Solving $v = \frac{4}{3}\pi r^3$ for r

$v = \frac{4}{3}\pi r^3$

Multiplying whole equation by 3/4

$\frac{3}{4}.v = \frac{3}{4}.\frac{4}{3} \pi r^3$

$\frac{3}{4}v = \pi r^3$

Dividing by Pi on both sides

$\frac{3v}{4\pi} = \frac{\pi r^3}{\pi}\\\frac{3v}{4\pi} = r^3$

Taking cube root on both sides

$\sqrt[3]{r^3} = \sqrt[3]{\frac{3v}{4\pi}} \\r = \sqrt[3]{\frac{3v}{4\pi}}$

Now

Solving $a_{ave} = \frac{v_2-v_1}{t_2-t_1}$ for v2

Multiplying both sides by (t2-t1)

$(t_2-t_1)a_{ave} = \frac{v_2-v_1}{t_2-t_1}(t_2-t_1)\\(t_2-t_1)a_{ave} = v_2-v_1$

Adding v1 on both sides

$(t_2-t_1)a_{ave}+v_1 = v_2-v_1+v_1\\(t_2-t_1)a_{ave}+v_1 = v_2$

Hence,

Solving $v = \frac{4}{3}\pi r^3$ for r gives us: $r=\sqrt[3]{\frac{3v}{4\pi}}$

Solving $a_{ave} = \frac{v_2-v_1}{t_2-t_1}$ for v2 gives us: $v_2 = (t_2-t_1)a_{ave}+v_1$

Chandani purchased some parrots. 20% flew away and 5% died. Of the remaining, 45% were sold. Now 33 parrots remain. How many par

Paha777 [63]

Answer:

80 parrots were purchased.

Step-by-step explanation:

Let the total number of parrots be k.

If 20% (or 20/100 = 1/5) flew away and 5% (5/100 = 1/20) died, the remaining parrots will be k – (¹/₅k + ¹/₂₀k) = k – ¼k = ¾k.

Of the remaining, 45% (or 45/100 = 9/20) were sold, which means the total number of sold parrots will be ¾k × ⁹/₂₀ = ²⁷/₈₀k.

The remaining parrots = ¾k – ²⁷/₈₀k = ³³/₈₀k = 33

k = 33 × ⁸⁰/₃₃ = 80 parrots were purchased.
