Answer:

A=6250\ feet^2

Step-by-step explanation:

Given that,

The radius of circle, r = 50 feet

The central angle, \theta=5\ radian

We need to find the area of the sector of a circle. The formula for the area of sector is given by :

A=\dfrac{1}{2}r^2\theta\\\\=\dfrac{1}{2}\times 50^2\times 5\\\\A=6250\ feet^2

So, the area f the sector of the circle is 6250\ feet^2.

Find three consecutive integers such that three times the first added to the last is 22
Finger [1]
Consetive integers are 1 apart
they are
x,x+1,x+2

3 times the first added to the last is 22
3x+x+2=22
combine like terms
4x+2=22
minus 2 both sides
4x=20
divide both sides by 4
x=5
x+1=6
x+2=7

What is the relationship between the 6s in 6,600 value of the given digits?
Karolina [17]

The relationship between the 6s in 6,600 value of the given digits

We write the numbers in place value chart

Thousand     Hundreds          Tens      Ones

 6                     6                        0             0

first 6 is in thousands place

next 6 is in hundreds place

6 thousand is 10 times greater than 6 hundred

6000 is 10 times greater than 600

5. A deck should have a perimeter of 90 feet and a minimum area
Ket [755]

Answer:

The minimum value of the width is 15 ft and the maximum value of the width is 30 ft

Step-by-step explanation:

Let

x -----> the length of the deck

y ----> the width of the deck

we know that

The perimeter of the deck is equal to

P=2(x+y)

P=90\ ft

so

90=2(x+y)

45=(x+y)

x=45-y -----> equation A

The area is equal to

xy\geq 450 -----> inequality B  

(45-y)y\geq 450\\ \\-y^{2} +45y-450\geq 0

Solve the quadratic equation by graphing

The possible width of the deck are the values of y in the interval

[15,30]

All real numbers greater than or equal to 15 ft and less than or equal to 30 ft

see the attached figure

The minimum value of the width is 15 ft and the maximum value of the width is 30 ft
