Andy will spend 12$ in wire.

We know this because he wants 25 ft of wire and there are 300 inches in 25ft

In the chart it says 150 inches is 6$ so if we multiply that by 2 we get the price for 300 inches which is 12$

Hope this helps :) comment if you need anymore help!

Eliminate the parameter.<br><br> x = 3 cos t, y = 3 sin t
ElenaW [278]

Answer:

x^2+y^2 = 3^2

Step-by-step explanation:

We need to eliminate the parameter t

Given:

x = 3 cos t

y = 3 sin t

Squaring the above both equations

(x)^2=(3 cos t)^2

(y)^2 =(3 sin t)^2

x^2 = 3^2 cos^2t

y^2=3^2 sin^2t

Now adding both equations

x^2+y^2=3^2 cos^2t+3^2 sin^2t

Taking 3^2 common

x^2+y^2=3^2 (cos^2t+sin^2t)

We know that cos^2t+sin^2t = 1

so, putting the value

x^2+y^2=3^2(1)

x^2+y^2 = 3^2

Hence the parameter t is eliminated.

How do you reduce 2 1/32
loris [4]

Answer:

2\frac{1}{32}=\frac{2\cdot 32+1}{32}=\frac{65}{32}

Step-by-step explanation:

Considering the expression

2\frac{1}{32}

As

\mathrm{Convert\:mixed\:numbers\:to\:improper\:fraction:}\:a\frac{b}{c}=\frac{a\cdot \:c+b}{c}

<em>Improper fraction is a fraction which has numerator greater than denominator, such as 5/3.</em>

So,

2\frac{1}{32}=\frac{2\cdot 32+1}{32}=\frac{65}{32}

As 2\frac{1}{32} is converted into improper fraction  \frac{65}{32} .

And  \frac{65}{32} can not be further reduced.

Therefore,

2\frac{1}{32}=\frac{2\cdot 32+1}{32}=\frac{65}{32}

Keywords: fraction, reduced form, improper fraction
