6. The length of a football field is 30 yards more than its width.
Express the length of the field in terms of its width. If the perimeter
of the field is 340 yards. find the width of the field. I

Answers

Answer 1

Answer:

the width be 70 yards

Step-by-step explanation:

The computation of the width of the field is as follows:

As we know that

The Perimeter of the rectangle is

= 2 × (length + width)

Where

Perimeter is 340 yards

Let us assume the width be x

So, the length would be x + 30

Now put these values to the above formula

340 = 2 × (x + x + 30)

340 = 2 × (2x + 30)

340 = 4x + 60

4x = 280

x = 70

The length would be

= 70 + 30

= 100

Hence, the width be 70 yards

(05.05) On a coordinate plane the coordinates of vertices R and T for a polygon are R(-7, 3) and T(3,3). What is the length of Side RT of the polygon?
4 units
6 unts
10 units
15 units
PLEASE HELP!!

Answers

Answer:

c) 10 units

The length of side RT of the polygon  RT = 10

Step-by-step explanation:

Step(i):-

Given the coordinates of vertices R and T

R( -7 ,3) and T (3 ,3)

we have to find the length of side RT

We will use distance formula

RT  = [tex]\sqrt{(x_{2} -x_{1})^{2} +(y_{2} -y_{1} )^{2} }[/tex]

Step(ii):-

RT  [tex]= \sqrt{(3-3)^{2} +(3-(-7))^{2} }[/tex]

[tex]RT = \sqrt{0+(10)^{2} }[/tex]

RT = √100

RT = 10

The length of side RT of the polygon  RT = 10

AC=7(5)−10 Substitution Property of Equality
AC=35−10 Simplify.
AC=25 Simplify.

Answers

Answer:

See proof below

Step-by-step explanation:

If C is the midpoint of AB, then AC = CB

Given

AC=7x−10;

CB=3x+10

Then 7x - 10= 3x+10

Add 10 to both sides

7x-10+10 = 3x +10+10

7x = 3x + 20

7x - 3x   = 10+10

4x = 20

x = 20/4

x = 5

Get AC

AC = 7x - 10

AC= 7(5) - 10

AC = 35-10

AC = 25 (Proved)

What is  square pyramid?

A square pyramid has a square base and four lateral faces in geometry. A pyramid is a polyhedron with a base and three or more triangular faces that meet above it . A square pyramid, also known as a pentahedron, is a three-dimensional geometry with a total of five faces.

How to solve?

As ancient pyramid models were in shape of square pyramid hence we apply

[tex]A = a(a + \sqrt{ (a^{2} + 4h^{2} ))}[/tex]

where a =25cm

and h=30 cm

[tex]A = 25(25 + \sqrt{ (25^{2} + 4(30^{2}) ))}[/tex]

=25(25+65)

=2250[tex]cm^{2}[/tex]
