Sav [38]

Answer:

6.36l

Step-by-step explanation:

We compute first the volume:

V=pi×h/3×(R²+r²+rR), where h=20cm is the height, R=24/2=12cm is the top radius, r=16/2=8cm is the bottom radius.

We get: V=pi×20/3(12²+8²+12×8)=

20×pi/3(144+64+96)cm³

V=20×pi/3×304=6363.73cm³

In dm³ we have (divide by 1000) V=6.36dm³

By definition, 1dm³=1l, so the capacity is 6.36l

The percent of working students increased 21.7% to 8.9%, what was the percent prior to increase

blagie [28]

Answer:

Approximately 7.3%.

Step-by-step explanation:

What is percentage increase?

$\displaystyle \text{Percentage Increase} = \frac{\text{Final Value} - \text{Initial Value}}{\text{Initial Value}} \times 100\%$ .

For this question:

$\text{Percentage Increase} = 21.7\%$ ,
$\text{Final Value} = 8.9\% = 0.089$ , and
$\text{Initial Value}$ needs to be found.

Let $\text{Initial Value} = x$ .

$\displaystyle \frac{0.089 - x}{x} = 0.217$ .

Assume that $x \ne 0$ . Multiply both sides of the equation by $x$ :

$0.089 - x = 0.217x$ .

Add $x$ to both sides of the equation:

$0.089 = (1 + 0.217)x$ .

$\displaystyle x = \frac{0.089}{1 + 0.217} = 0.0731 \approx 7.3\%$ .

In other words, the initial percentage is approximately 7.3%.

Let's take this variable by variable. z to the power of 4 over z to the power of one would equal z to the power of 3. At this point, there is no longer a z variable in the denominator.
X to the power of 2 over x to the power of 1 would equal x. At this point there is also no x variable in the denominator.
Y to the power of 1 over y to the power of 2 would equal (1/y). At this point, there is no y in the NUMERATOR.

Final Answer: $\frac{ z^{3}x }{y}$
