A circular flower bed is 24 m in diameter and has a circular sidewalk around it that is 2 m wide. Find the area of the sidewalk in the square meters.

Answers

Answer 1

The area of the sidewalk is 144.44 m².

The 2-m wide walk adds 4 m to the diameter, making it 21+4=25.

Since the radius is half the diameter, r = 25/2 = 12.5.

The area of the entire bed with walkway is 3.14(12.5)² = 490.625 m².

The diameter of the bed is 21, so the radius is 21/2 = 10.5.
The area of just the flower bed is 3.14(10.5)² = 346.185.

The difference between the two is 490.625-346.185 = 144.44 m². This is the area of the walkway.

5x + 10y = -5
-5 - y = 32

Answers

y= -27
x= 53

solving for y:

-5-y=32

add y to both sides

-y = 27

divide by -1

y= -27

solving for x

plug in -27 for y in the first equation

5x +10(-27) =-5

5x+ (-270) =-5

add 270 to both sides

5x= 265

divide by 5 on both sides

x= 53

Name this polynomial by its degree: 3x² + 5x-3

Answers

Answer:

[tex]\boxed{\textsf {The given polynomial is a quadratic polynomial. }}[/tex]

Step-by-step explanation:

A polynomial is given to us and we need to make the polynomial by its degree . Here the given polynomial is 3x² + 5x -3 .

[tex]\sf\implies p(x)= 3x^2+5x-3 [/tex]

So here we can see that the highest power of the variable in the given polynomial is 2 . So the polynomial is a quadratic polynomial .

★ More to Know :-

When we equate this quadratic polynomial with 0 , it becomes a quadratic equation.

That is ,

[tex]\sf\implies p(x)= 3x^2+5x-3=0[/tex]

This is done in order to find the zeroes of the polynomial. The zeroes of the polynomial are the values for which the polynomial becomes 0 .

5/7x - 14 = -22. Find x.

Answers

Answer:

x = -56/5, -11 1/5, or -11.2

Step-by-step explanation:

5/7x - 14 = -22

5x -98 = -154

5x = -154 + 98

5x = -56

x = -56/5, -11 1/5, or -11.2

Answer:

x= -11.2

Step-by-step explanation:

5/7x-14=-22

+14 +14 Add 14 on both sides

5/7x = -8

(7/5)*5/7x = -8*(7/5) Multiply by the reciprocal on both sides to leave x alone

Another submarine's descent can be represented as `y=-240x`, where u is the elevation and x is time in hours. How long will it take this submarine to make the descent (2,100 feet below the surface)?

Answers

Answer:

The time it will take is 8hours 45mins.

Step-by-step explanation:

Since y = –240x represents a submarine descent. We are looking for how long, that is the time, it will take for the submarine to make a descent of 2100. We know that y is the elevation, if it is descending it will be in the negative direction, making it -ve.

A descent of 2100 means y = –2100. Hence,

–2100 = –240x

x = –2100/–240 = 8.75hours = 8hours 45minutes. (0.75hours = 3/4hours = 3/4 x 60mins = 45mins).
