area of 81 square feet? Use 3.14 for pi, round your answer to the nearest hundredth

Answers

Answer 1

Answer:

63.59

Step-by-step explanation:

Side of square = √81 = 9

Diameter of circle is 9 so radius is 4.5

Area = πr^2 = 3.14(4.5)^2 = 63.59

4(4 – 12x) – 2(x – 12) + 5x = –50?

Answers

The value of x of the given equation is 2.

What is equation?

An equation is a mathematical statement that is made up of two expressions connected by an equal sign. Equation, statement of equality between two expressions consisting of variables and/or numbers.

Given:

The given equation is

4(4 – 12x) – 2(x – 12) + 5x = –50

We have to find the value of x.

According to given question we have

4(4 – 12x) – 2(x – 12) + 5x = –50

Rearrange terms we get,

4(– 12x+4) – 2(x – 12) + 5x = –50

Distribute we get,

-48x+16-2x+24+5x=-50

Compare the like terms we get,

-45x=-50-40

-45x=-90

x=2

Therefore, the value of x of the given equation is 2.

Describe at least two differences between constructing an inscribed regular hexagon and constructing an inscribed square.

100 points and brainliest

Answers

There are some differences in the process of constructing a inscribed square and a hexagon inside a circle.

When constructing a square, we start with a circle. Then draw its diameter through the center of the circle. Now putting compass on end points of this diameter, measuring more than half the length of diameter on the compass, draw 4 arcs above and below the diameter. So we get a perpendicular bisector of the diameter. In total, we get 4 points on the circle. Joining the adjacent points, we get the inscribed square.

When constructing the regular hexagon, start drawing a circle. Put the compass on a point on the circle and measure the radius on it. Now draw an arc on the circle. Putting compass on this new point on the circle draw another arc. Continuing like this, we get a total of  6 arcs giving 6 points on the circle. Join the adjacent points to get an inscribed regular hexagon.

So the differences in constructing the square and the regular hexagon are:

Diameter is used in square whereas radius is enough for the regular hexagonPerpendicular bisector is constructed for square while regular hexagon does not need one.For a square,4 arcs giving 4 points on the circle are needed. But for a regular hexagon 6 arcs giving 6 points are there.

Which equation represents a line through (4, -6) and (0, 2)?

Answers

Answer: C

Step-by-step explanation: Substitute four and zero in each of the choices and see if the sum becomes negative six and two, respectively. If it does, then the equation represents the line.

Third equation substitution:

x = 4

y = -2(4) + 2

y = -8 + 2

y = -6

x = 0

y = -2(0) + 2

y= 0 + 2

y = 2

Therefore, the answer is C.

joe and millie each have some baseball cards, and ¾ of the number of cards joe has is equal to 2/3 of the number of cards millie has. what is the least number of cards they could have altogether?

Answers

So, the least number of cards they could have altogether is any value of integer Z, that is ranging from (0→∞). If starting from n=1, then X=8 and Y=9.

What is an integer?

A whole number that can be either positive, negative, or zero is known as an integer.

Let Joe has x no. of cards,

then,

Millie has (3/4)x cards.

In that case, Let millie has a total y no. of cards,

then, Joe has (2/3) y cards.

This means that,

(3X)/4 = (2Y)/3

The alternate form shall be:

X = (8 Y)/9

(3 X)/4 - (2 Y)/3 = 0

Real solution:

Y=(9X)/8

Integer Solution shall be:

X=8n, Y=9n, n∈Z, where Z is the set of integers.

So, the least number of cards they could have altogether is any value of integer Z, that is ranging from (0→∞). If starting from n=1, then X=8 and Y=9.

The vertex of the parabola of the quadratic function that is increasing in the interval (-∞, 2), and decreasing in the interval (2, ∞), is the highest point on the parabola.

How can the type of vertex be found from the description of the quadratic function?

The given description of the quadratic function is presented as follows;

The interval the function is increasing = (-∞, 2)

The interval the function is decreasing = (2, ∞)

The graph of the function is therefore increasing from -∞ up to the point just before 2.

The graph of the function is decreasing from the point just after 2 to infinity.

The point 2 is therefore the highest point of the graph and also, the vertex of the quadratic function.

Answers

The maximum number of meals the family can eat at the restaurant is 11

Amount saved by Dana for her upcoming vacation = 450

Average cost when Dana cooks lunch or dinner  = 10

Average cost when the family goes to a restaurant for lunch or dinner = 40

Maximum number of meals the family can have at the restaurant  = Amount saved by Dana/Average cost of a meal when the family goes to a restaurant

=450/40

= 11.25 or 11

So, the maximum number of meals the family can eat at the restaurant is 11 with a budget of 450.

Step-by-step explanation:

The solution to the given system of equations are:{ x = 1, y = 1, z = 2} which is the corrrect answer would be option (A).

What is an equation?

The equation is defined as a mathematical statement with at least two terms that contain variables or values that are equal.

We have been given the system of equations as:

2x − y − z = −1

3x + y − z = 2

x + y − 5z = −8

Isolate the term of x in the equation 2x − y − z = −1, and we get

x = (- 1 + y +z)/2

Substitute the value of x = (- 1 + y +z)/2 in the above both equations,

3(- 1 + y +z)/2 + y − z = 2

(- 1 + y +z)/2 + y − 5z = −8

Simplify the equation to you get,

(5y + z - 3) / 2 = 2

(3y - 9z - 1) / 2 = -8

Isolate the term of y : (5y + z - 3) / 2 = 2 ⇒ y = (-z +7 )/5

Substitute the value of y = (-z +7 )/5 in the equation (3y - 9z - 1) / 2 = -8

(3(-z +7 )/5 - 9z - 1) / 2 = -8

Simplify the equation to you get,

8(-3z + 1)/d = -8

Isolate the term of z : 8(-3z + 1)/d = -8 ⇒ z = 2

Substitute the value of z = 2 in the equation y = (-z + 7) / 5 to simplify to get

⇒ y = 1

Substitute the values of y = 1 and z = 2 in the equation x = (-1 + y + z) / 2 to simplify to get

⇒ x = 1
