Answer: 26.7m
Step-by-step explanation:
Since a decagon has 10 sides, you'll have to divide 267m by 10.
267÷10= 26.7
One side of the decagon is 26.7m

Circle C has radius 5 and center C(6,-2). What is the equation of circle C ?
The equation of the circle C is [tex](x-6)^{2}+(y+2)^{2} =25[/tex]
Equation of a circle
The equation of a circle is [tex](x-h)^{2}+(y-k)^{2} =r^{2}[/tex] where r is the radius and (h,k) is the center of a circle.
How to find the equation of a circle for the given condition?The radius of a circle is 5.
Also, the center of a circle is (h,k) = (6,-2)
So, the equation of a circle is [tex](x-6)^{2}+(y-(-2))^{2} =5^{2}[/tex]
Simplify further the above equation.
[tex](x-6)^{2}+(y+2)^{2} =25[/tex]
Thus, the equation of the circle C is [tex](x-6)^{2}+(y+2)^{2} =25[/tex]
Hence, option (D) is correct.

lydia wants to purchase guitar lessons she sees a sign that gives the price is 47 guitar lessons and 11 guitar lessons write a linear equation to find the total cost c for d lessons
Answer:
c = 58x
Step-by-step explanation:
A linear equation is an equation in the form of f(x) = mx + c. Where m is the slope and c is the intercept.
Let the price of one guitar lessons be x, then 47guitars will be 47x and 11 guitar lessons will be 11x. All together will be 47x + 11x = 58x.
Thus, the total cost, c, is

Graph the following system of inequalities.
y>1/3x-2
y <-4x-2
Graph-X represents the given set of inequalities.
What is inequality?"An inequality is a relation which makes a non-equal comparison between two numbers or other mathematical expressions."
Given two inequalities are:
1. y > (1/3)x - 2
If we compare it with the slope-intercept form of a line, then:
Slope = 1/3, y-intercept = - 2
Therefore, the line cuts the y-axis at x = - 2.
Here, the greater than sign indicates that the graph would be shaded down.
2. y < - 4x - 2
If we compare it with the slope-intercept form of a line, then:
Slope = - 4, y-intercept = - 2
Therefore, the line cuts the y-axis at x = - 2.
Here, the less than sign indicates that the graph would be shaded up.
Therefore, Graph-X represents the given set of inequalities.

Taylor is 15 years younger than Marty. Twice Marty’s age added to three times Taylors age totals 205. What are the ages of Taylor & Marty?
Answer:
Taylor's age = x = 35 years
Marty's age = y = 50 years
Step-by-step explanation:
Let
Taylor's age = x
Marty's age = y
Taylor is 15 years younger than Marty.
x = y - 15
Twice Marty’s age added to three times Taylors age totals 205.
205 = 2y + 3x...... Equation 1
Therefore, we substitute y - 15 for x in
205 = 2y + 3x...... Equation 1
205 = 2y + 3(y - 15)
205 = 2y + 3y - 45
Collect like terms
205 + 45 = 5y
250 = 5y
y = 250/5
y = 50 years
x = y - 15
x = 50 - 15
x = 35 years
Solving for x
Therefore:
Taylor's age = x = 35 years
Marty's age = y = 50 years

Correct question
A sequence is defined by the term-to-term rule
Un+1 = u. + 3
Given that u1 = 1,
a) find u2
b) find u3
c) find u5
a) Given the recursive formula;
Un+1 = un + 3
When n = 1;
U1+1 = U1 + 3
U2 = U1 + 3
U2 = 1 + 3
U2 = 4
b) U3 = U2 + 3
U3 = 4 + 3
U3 =7
c) U4 = U3 + 3
U4 = 7+3
U4 = 10
U5 = U4 + 3
U5 = 10 + 3
U5 = 13

Okay so I have no clue what to do on these problems lol. Can someone help explain it please? Thank you
Answer:
you use the Pythagorean theorem (a^2 +b^2 = c^2)
a^2 +17^2 = 19^2
a^2 + 289 = 361
a^2 = 72
a = (square root)72
5^2 + 13^2 = c^2
25 + 169 = c^2
194 = c^2
c= (square root)194
a^2 + 10^2 = 20^2
a^2 + 100 = 400
a^2 = 300
a = (square root) 300
5^2 + 14^2 = c^2
25 + 196 = c^2
221 = c^2
c= (square root) 221
Step-by-step explanation:
it says to leave it as it's simplest radical form, i can't put a square root on the screen, but put the number inside the radical and leave it like that.

(a) Type an equation and (b) solve. Type the answers in the spaces provided. In the basketball championship game, the Falcons had three fewer than twice as many Bears players. If the Falcons had 11 players, how many players were on the Bears? (Use b as the variable.) (a) (b) Bears:
Answer:
There were 7 players on the Bears
Step-by-step explanation:
Given
[tex]a = falcons[/tex]
[tex]b = bears[/tex]
We have that:
[tex]a = 11[/tex]
and also:
[tex]a = 2b - 3[/tex] --- 3 fewer than twice a
Required
Solve for b
Substitute 11 for a in [tex]a = 2b - 3[/tex]
[tex]11 = 2b - 3[/tex]
Add 3 to both sides
[tex]3+11 = 2b - 3+3[/tex]
[tex]3+11 = 2b[/tex]
[tex]14 = 2b[/tex]
Divide both sides by 2
[tex]\frac{14}{2} = \frac{2b}{2}[/tex]
[tex]7 = b[/tex]
[tex]b = 7[/tex]
Hence, there were 7 players on the Bears
