This is a pond in the shape of a prism. it is completely full of water colin uses a pump to empty the pond. The level goes down

lapo4ka [179]

The required time is mathematically given as

t-150 minutes.

This is further explained below.

We know that the volume of the prism is given by.

Volume $$=$ (Base Area $) \times$ Height$

Base Area $=\frac{1}{2} \times(1.4+0.6) \times 2$

Base Area $=2 \mathrm{~m}^2$

Now,

$Volume $=2 \times 1=2 \mathrm{~m}^3$$

Given that there is a twenty percent drop in the level of the pond during the first thirty minutes.

Because of this, the volume increases.

$Volume $=2 \times 0.8=1.6 \mathrm{~m}^3$

Now, the rate of emptying the tank is,

$=\frac{2-1.6}{30}=\frac{1}{75} \mathrm{~m}^3 / \mathrm{min}$

In conclusion, We also know that,

$$

$\begin{aligned}&\text { time }=\frac{\text { volume }}{\text { rate }} \\&\text { time }=\frac{2}{\frac{1}{75}}-150 \mathrm{~min}\end{aligned}$

Therefore, Colin must wait for the pond to drain for a total of 150 minutes.

A bucket of paint has spilled on a tile floor. The paint flow can be expressed with the function r(t) = 3t, where t represents time in minutes and r represents how far the paint is spreading.

The flowing paint is creating a circular pattern on the tile. The area of the pattern can be expressed as A(r) = πr2.

Part A: Find the area of the circle of spilled paint as a function of time, or A[r(t)]. Show your work.

Part B: How large is the area of spilled paint after 10 minutes? You may use 3.14 to approximate π in this problem.

Write a system of equations to describe the situation below, solve using elimination, and fill in the blanks. At a historical la

Alborosie

Answer:

The number of candles will hold 2 candles

And large candle holder will hold 6 candles.

Step-by-step explanation:

Let the number of candles small candle holder have x

And the number of candles large candle holder have y

So, according to the information given in the question:

17 small candle holders means 17 x

and 2 large candle holders means 2y

using a total of 46 candles means $17x+2y=46$ (1)

Similarly, 8 small candle holders and 2 large candle holders, for a total of 28 candles gives:

$8x+2y=28$ (2)

We will solve equation (1) and (2) by elimination method:

Subtractijng the two equations we get:

$9x=18$

$\Rightarrow x=2$

Substitute x=2 in equation(2) we get: $8(2)+2y=28$

$2y=12$

$\Rightarrow y=6$

So, the number of candles will hold 2 candles

And large candle holder will hold 6 candles.
