A group of students wants to find the diameter of the trunk of a young sequoia tree. The students wrap a rope around the tree trunk

Answers

Answer 1

Answer:

the length of the rope gives the circumference of the tree trunk. the tree trunk is in the shape of a circle. the circumference of a circle = πD. the inches would be converted to foot and the diameter would be determined from the length of the  rope.

7 foot

Step-by-step explanation:

Here is the full question :

A group of students wants to find the diameter of the trunk of a young sequoia tree. The students wrap a rope around the tree trunk. the length is 21 feet 8 inches

Explain how they can use the length to determine the diameter of the tree trunk to the nearest half foot

What is the diameter of the tree trunk

the circumference of a circle = πD

π = 22/ 7

D = diameter

we need to convert 21 feet 8 inches to foot

1 inch = 0.0833333 foot

8 x 0.0833333 = 0.667

0.667 + 21 = 21.667 foot

21.667 = 22/7 x diameter

diameter = 21.667 x 7/22 = 6.89 foot

The nearest half foot of 6.89 is 7.

7 foot

Answer:

x = 11

Step-by-step explanation:

24+4x=6x+2

substract 2x from both sides 4x-4x and 6x -4x

24 = 2x + 2

Substract 2 from both sides 24-2 and 2-2

22 = 2x

Divide by 2 to both sides 22/2 and 2x/2

x = 11

Lucy Liu went shopping at Hollister with her friends together they spent a mean price of $40 on eight sweaters the first step and sweaters cost $50 $55 $30 $35 $39 $40 and $42 how much in dollars does the eighth sweater cost

Answers

Answer:he eighth sweater costs $29

Step-by-step explanation:

Let the price of the eighth sweater be re[presented as X

We know that

Mean Price =Total sum of cost of sweater bought/ Number of sweater'

Plugging in our known values we have that  

40=$50+ $55+ $30+ $35+ $39+ $40 + $42+X  /8

8 X 40 =291 +X

320=291 +X

X =320-291

X=29

Therefore, the eighth sweater costs $29

An architect designs two similar triangular patios. The first patio has angle measures of (x + 5)°, (y + 15)°, and 80°. The second patio has angle measures of (x + 25)°, 40°, and 60°. Find the values of x and y. please answer fast! i just need this one!

Answers

Answer:

x = 55° and y = 25°

Step-by-step explanation:

Since we have two triangular patios with angles  (x + 5)°, (y + 15)°, and 80° and the second patio has angles, (x + 25)°, 40°, and 60° respectively, and the sum of angles in a triangle is 180, we have that,

(x + 5)° + (y + 15)° + 80° = 180° and

(x + 25)° + 40° + 60° = 180°

Simplifying both expressions, we have

x + 5° + y + 15° + 80° = 180° and

x + 25° + 40° + 60° = 180°

collecting like terms, we have

x  + y + 5° + 15° + 80° = 180° and

x + 25° + 40° + 60° = 180°

Adding the like terms, we have

x  + y + 100° = 180°  and

x + 125° = 180°

So,

x  + y = 180° - 100° and

x = 180° - 125°

Thus,

x  + y = 80°   and

x = 55°  

So, y = 80° - x = 80° - 55° = 25°

So, x = 55° and y = 25°

Can someone help me with this problem 3(x+1)=11 I need it step by step

Answers

Answer:

x = 2.66666667

Step-by-step explanation:

3(x + 1) = 11

We multiply both x and 1 by 3 and get

3x + 3 = 11

Now we subtract 3 from both sides

3x + 3 - 3 = 11 - 3

3x = 8

Now divide both sides by 3

3x/3 = 8/3

x = 2.66666667

(っ◔◡◔)っ ♥ Hope It Helps ♥

3(x+1)=11
remove the parenthesis
3x+1=11
move the constant to the right side and change the sign
3x=11-3
subtract
3x=8
divide both sides by 3
x=8/3 or 2 2/3

A= pi r²

Step-by-step explanation:

Sorry i dont know how to do the pi symbol

Answer:

( x + 2 )² + ( y - 1 )² = 25

Step-by-step explanation:

Circle equation - ( x - h )² + ( y - k )² = r²

Important notes:

(h,k) = center

r = radius

The first step would be to find the center

( it's hard to explain how to find the center point virtually but the center point is at (-2,1) )

Like stated before ( h , k )  = center point

* replace center point with (-2,1) *

( h , k ) = ( -2 , 1 )

h = -2

k = 1

* plug in the h and k values into the circle equation *

now we have ( x - ( -2) )² + ( y - 1 )²

Now to find the radius

We can find the radius by using the distance formula with the center point and any point on the circle's outline

The point chosen can vary but i chose (3,1)

Because the y value of the chosen point and the y value of the center are the same we can simply subtract the larger x value by the smaller x value to find the radius

3 - (-2)

the two negative signs cancel out

3 + 2 = 5

So the radius equals 5

* plug in the value of the radius into the equation *

Now we have

( x - (-2) )² + ( y - 1 )² = 5²

our final step is to simplify

- (-2) the two negative signs cancel out and it turns into +2

5² = 25

Our final answer would be ( x + 2 )² + ( y - 1 )² = 25

Given:

Number of apples purchased = 4

Number of oranges purchased = 7

To find:

The ratio of apples to oranges in two ways.

Solution:

Ratio of apples to oranges is:

[tex]Ratio=\dfrac{Apples}{Oranges}[/tex]

After substituting the given values, we get

[tex]Ratio=\dfrac{4}{7}[/tex]

[tex]Ratio=4:7[/tex]

Write the standard equation of the circle if the center is (-1,2), and a point on the circle is (2,6).

Plz help me someone​

Answers

Answer:

(x+1)²+(y-2)² = 25

Step-by-step explanation:

Standard equation of the circle is expressed as;

(x-a)²+(y-b)² = r²

(a,b) is the center of the circle

r is the radius

Get the radius

r = √(x2-x1)²+(y2-y1)²

r = √(2+1)²+(6-2)²

r = √3²+4²

r = √9+16

r = √25

r = 5

Substitute into the formula

(x-a)²+(y-b)² = r²

a = -1, b = 2, r = 5

(x-(-1))²+(y-2)² = 5²

(x+1)²+(y-2)² = 25

This gives the required equation
