(a)It takes 51

never [62]

a) Given :

51 pounds of seed can be planted in = 9 acre field.

Per pound of seed = $\frac{9 \ acre}{51 \ pounds \ of \ seed}$

We can convert 9/51 in simplest fraction by dividing top and bottom by 3.

We get

$\frac{9/3}{51/3}=\frac{3}{17}$

<h3>Therefore, 3/17 of an acrs can be planted per pound of seed.</h3>

b) $10 amount = 16 pounds of sugar.

$1 amount = 16/10 = 1.6 pounds of sugar.

<h3>Therefore, 1.6 pounds of sugar she got per dollar.</h3>

Is 2.73234(34 repeating) rational or irrational?

Fittoniya [83]

It's rational because of the repeating digits.

We have

x = 2.732343434…

Then

1,000x = 2,732.343434…

and

100,000x = 273,234.343434…

Subtracting these makes the fractional part go away, leaving you with

100,000x - 1,000x = 273,234.343434… - 2,732.343434…

100,000x - 1,000x = 273,234 - 2,732

99,000x = 270,502

x = 270,502/99,000 = 135,251/49,500

which is clearly a rational number.

A salt water solution is cooled to -3C. During an experiment , the mixture is heated so that its, temperature rises at steady ra

JulijaS [17]

Answer:

$y = -3+ rx$

Step-by-step explanation:

Given

$Base = -3C$

$Time = x$

Required

Determine the equation (y)

Let the steady rate be represented with r.

So, the equation (y) can be determined using:

$y = Base + Rate * Time$

$y = -3+ r* x$

$y = -3+ rx$
