Answers

Answer 1

Answer:

x=5/2

Step-by-step explanation:

4x-7=8-2x

add 7 to both sides

4x=15-2x

add 2x to both sides

6x=15

6/6x=15/6

x=5/2

Law of cosines: a2 = b2 + c2 – 2bccos(A)

Which equation correctly applies the law of cosines to solve for an unknown angle measure?

72 = 82 + 112 – 2(8)(11)cos(N)
82 = 72 + 112 – 2(7)(11)cos(M)
72 = 82 + 112 – 2(8)(11)cos(P)
82 = 72 + 112 – 2(7)(11)cos(P)

The equation correctly applies the law of cosines to solve for an unknown angle measure is equation D.

What is a Triangle?

A triangle is a polygon with three sides, three vertices, and three angles.

The length of P N is 7,

The length of N M is 8, and

The length of M P is 11.

The law of cosines is used to determine the missing sides and angles if two sides and an angle are given or three sides are given respectively.

The equation that correctly applies should have the two sides and the cosine of the included angle.

The correct equation is 8² = 7² + 11² – 2(7)(11)cos(P)

The square has a side length of 10 ft and the circle inside the square has a diameter of 10 ft find the approximate area of the shaded region use 3.14 as an estimation for

Answers

Answer:

[tex]Area = 21.5ft^2[/tex]

Step-by-step explanation:

See attachment

Given

Square:

[tex]Length = 10ft[/tex]

Circle:

[tex]Diameter = 10ft[/tex]

[tex]\pi = 3.14[/tex]

Required: Calculate the area of the shaded region

First, calculate the area of the square:

[tex]A_1 = Length^2[/tex]

[tex]A_1 = (10ft)^2[/tex]

[tex]A_1 = 100ft^2[/tex]

Next, the area of the circle.

[tex]A_2 =\pi * \frac{d^2}{4}[/tex]

[tex]A_2 =3.14 * \frac{10^2}{4}[/tex]

[tex]A_2 =3.14 * \frac{100}{4}[/tex]

[tex]A_2 =3.14 * 25[/tex]

[tex]A_2 =78.5ft^2[/tex]

The shaded region has the following area

[tex]Area = A_1 - A_2[/tex]

i.e. the difference between the area of the square and  the area of the circle

[tex]Area = 100ft^2 - 78.5ft^2[/tex]

[tex]Area = 21.5ft^2[/tex]

You're doing this because if you have z-31=16 you have to + 31 to 16 which would give you 47 then that would be a one step equation

z-31=16

you would make a line between the equal sign so it is organized then plus 31 to sixteen then that would get you to 47
