Marta is solving the equation S = 2πrh + 2πr2 for h. Which should be the result?

StartFraction S Over 2 pi r EndFraction equals h. – r = h
StartFraction S minus r Over 2 pi r EndFraction equals h. = h
S – S minus StartFraction r Over 2 pi EndFraction equals h. = h
S – S minus StartFraction 2 pi Over r EndFraction equals h. = h

Answers

Answer 1

Answer:

(S-2πr^2)/ 2πr = h

Step-by-step explanation:

S = 2πrh + 2πr^2

Subtract 2 pi r^2 from each side

S-2πr^2  = 2πrh + 2πr^2 -2πr^2

S-2πr^2  = 2πrh

Divide each side by 2 pi r

(S-2πr^2)/ 2πr = 2πrh/2πr

(S-2πr^2)/ 2πr = h

Answer 2

It is given that,

→ S = 2πrh + 2πr²

Now subtract 2πr² from the both sides,

→ S - 2πr² = 2πrh + 2πr² - 2πr²

→ S - 2πr² = 2πrh

Then divide both sides by 2πr,

→ (S-2πr²)/2πr = 2πrh/2πr

→ (S-2πr²)/2πr = h

Hence, (S-2πr²)/2πr = h is the result.

What is Ava’s net pay each month?

Answers

Explanation:

Gross pay is what’s made before taxes and necessary deductions, net pay is after taxes and necessary deductions. So we minus the deductions to find the net pay. The equation is 2,500 - 290 - 85 - 112 - 35 = ? . The answer is $1,978.

Answers

Answer:

[tex](a)\ y = 4\ or\ y = -\frac{1}{2}[/tex]

[tex](b)\ x = 2 \ or\ x = -\frac{1}{4}[/tex]

Step-by-step explanation:

Solving (a)

[tex]2y^2 - 7y - 4 = 0[/tex]

Expand

[tex]2y^2 +y - 8y - 4 = 0[/tex]

Expand

[tex]y(2y + 1) -4(2y + 1) = 0[/tex]

Factor out 2y + 1

[tex](y -4)(2y + 1) = 0[/tex]

Split

[tex]y - 4 =0\ or\ 2y + 1 = 0[/tex]

Solve:

[tex]y = 4\ or\ y = -\frac{1}{2}[/tex]

Solving (b):

[tex]2(2x)^2 - 7(2x) - 4 = 0[/tex]

Compare the above with the equation in (a)

[tex]2y^2 - 7y - 4 = 0[/tex]

We have:

[tex]2x = y[/tex]

So:

[tex]2x = 4 \ or\ 2x = -\frac{1}{2}[/tex]

Solve for x in both cases

[tex]x = 2 \ or\ x = -\frac{1}{4}[/tex]

The polynomial function.

Solution:

The general polynomial function is defined as:

Where, a is the leading coefficient, [tex]c_1,c_2,...,c_n[/tex] are the zeros  with multiplicity [tex]m_1,m_2,...,m_n[/tex] respectively.

It is given that a polynomial function has a leading coefficient of 3 and roots 4, 1, and 2, all with multiplicity 1. So, the polynomial function is defined as:

[tex]P(x)=3(x-(-4))^1(x-1)^1(x-2)^1[/tex]

[tex]P(x)=3(x+4)(x-1)(x-2)[/tex]

Substitute y = 50 into the equation and solve for x

5x + 10(50) = 800 , that is

5x + 500 = 800 ( subtract 500 from both sides )

5x = 300 ( divide both sides by 5 )

Which defines a circle?

Answers

Answer:

a round figure that has no corners or vertices.

Step-by-step explanation:

Answer:

A circle is a shape consisting of all points in a plane that are at a given distance from a given point, the centre; equivalently it is the curve traced out by a point that moves in a plane so that its distance from a given point is constant. The distance between any point of the circle and the centre is called the radius. This article is about circles in Euclidean geometry, and, in particular, the Euclidean plane, except where otherwise noted.

Step-by-step explanation:

Center of a Circle

The center of a circle is the center point in a circle from which all the distances to the points on the circle are equal. This distance is called the radius of the circle.

Here, point P is the center of the circle.

A petting zoo gives out large buckets of healthy popcorn snacks for visitors to feed to the animals. what fraction of the snack is left in the bucket after a cow eats 1/3, a goose eats 1/12, and a goat eats 2/9?

Answers

Answer:

13/36 is left

Step-by-step explanation:

cow- 1/3 = 12/36

goose- 1/12 = 3/36

goat= 2/9 = 8/36

12 + 3 + 8 = 23/36

23/36 is consumed...

13/36 is left

The fraction of the snack left in the bucket will be 13/36.

What is a fraction?

The fraction is defined as the division of the whole part into an equal number of parts.

Given that:

cow- 1/3 = 12/36goose- 1/12 = 3/36goat= 2/9 = 8/36

The amount consumed is:-

( 12/ 36 )+ (3 / 36 ) +( 8 / 36 )  = 23/36

So the amount left will be calculated as:-

Amount left = 1 - ( 23 / 36 )

Amount left = ( 36 - 23 ) / 36

Amount left = 13 / 36

Therefore fraction of the snack left in the bucket will be 13/36.
