You have to divide the numerators by the denominators. Like for 1/2, you would do 1.0 divided by to which is 0.5. Hope this helps

Please help this is (finding the volume of a cone) any tips, answers anything ??

trasher [3.6K]

Answer:

Volume of a cone is v = πr²(h/3), So i think you just substitute the values for every step, 2nd step maybe v = 3.14(2²)(12/3) and then 3.14(4)(12/3) and then 12.56(12/3) then you divide by 3, then simplify from there. The radius =2 and the height is 12. Volume is about 50.24 if you use 3.14 as pi

Step-by-step explanation:

The equation of a cone is v = πr²(h/3), radius is 1/2 of diameter.

Enita is factoring the expression 32 a b minus 8 b. She determines the GCF and writes the factored expression as 8 b (4 a minus

sattari [20]

This shows that the greatest common factor is 8, Hence Venita's error is that she incorrectly determined the GCF.

<h3>Greatest common factor</h3>

Given the following expression

32ab - 8

Find the factors of each terms

32ab = 8 * 4. * a * b

8 = 8 * 1

Since 8 is common to both factors, hence

32ab - 8 = 8(4ab -1)

This shows that the greatest common factor is 8, Hence Venita's error is that she incorrectly determined the GCF.

a wire of length 200 cm is cut into two parts and each part is bent to form a square.If the area of the larger square is 9 times

diamong [38]

<em>Answer:</em>

<em>The perimeter of the larger square is $150cm.$ </em>

<em>Step-by-step explanation:</em>

<em>First of all, let one part of it be " $x$ "</em>

<em>and the other part of it " $200-x$ "</em>

<em>Now to solve this :</em>

<em>The area of the square = $L^2$ </em>

<em>The area of one part of the square = $x^2$ </em>

<em>The area of the other part of the square = $(200-x)^2$ </em>

<em> $9x^2= (200-x)^2\\9x^2=40000-400x+x^2$ </em>

<em></em>

<em>Now, add, $-4x^2$ to both the sides :</em>

<em> $9x^2-9x^2=40000-400x+x^2-9x^2\\-1(8x^2+400x-40000)=0$ </em>

<em />

<em>Now, take out the "8" which is common :</em>

<em> $-8(x^2+50x-5000)=0$ </em>

<em></em>

<em>Now, divide it by $-8$ :</em>

<em> $x^2+100x-50x-5000=0\\x(x+100)-50(x+100)=0\\(x+100)(x-50)=0\\$ </em>

<em> $x=-100$ or $50$ </em>

<em />

<em>So, now we know that :</em>

<em>One of the part is = $50cm$ </em>

<em>And the other part is = $150cm$ </em>

<em />

<em>Thus the perimeter of the larger square is = $150cm$ </em>
