A vintage wheel needs to be banded with an iron strip. If the wheel’s radius is 11 inches, how long must the iron strip be to go all the way around the wheel? Complete the steps below to answer the question.

Answers

Answer:

Step-by-step explanation:

first lets find the circumference of the wheel:

[tex]C=\pi *d[/tex]

we have to find the diameter out of the radius:

[tex]d=r*2[/tex]

because the radius is half of the diameter, intrhis case i have to findf the diameter so i do multiply it with 2:

[tex]r=11\\d=??\\d=11*2\\d=22[/tex]

we found the diameter now we are going to find the circumference :

[tex]C=\pi *d\\C=\ 3.14*22\\C= 69.08[/tex]

Another way (easier)to find the circumference is:

[tex]C=2\pi *r\\C=2(3.14)*11\\C=69.08[/tex]

At the end it will hav ethe same answer.

Answer:

69.08 inches

Step-by-step explanation:

substitute the values of r (11 inches) and pi (3.14) in the formula c = 2πr to find c:

c = 2 × 3.14 × 11 inches

c = 69.08 inches.

the circumference of the wheel is about 69.08 inches.

24x - 17 x ≥ 13x +15

Pls solve and add the equation if you can thank you :)

Answers

Given :-

[tex]24x - 17 x ≥ 13x +15[/tex]

Solving it,

[tex](24 - 17)x \geqslant 13x + 15[/tex]

[tex] = > 7x \geqslant 13x + 15[/tex]

[tex] = > 7x - 13x \geqslant 15[/tex]

[tex] = > (7 - 13) x \geqslant 15[/tex]

[tex] = > - 6x \geqslant 15[/tex]

[tex] = > x \leqslant - \frac{15}{6}[/tex]

By reducing to lowest terms, we get,

[tex]x \leqslant - \frac{5}{2}[/tex]

So, Value of x is [tex] - \frac{5}{2}[/tex]

Simplifying
24x + -17x = 13x + -15

Combine like terms: 24x + -17x = 7x
7x = 13x + -15

Reorder the terms:
7x = -15 + 13x

Solving
7x = -15 + 13x

Solving for variable 'x'.

Move all terms containing x to the left, all other terms to the right.

Add '-13x' to each side of the equation.
7x + -13x = -15 + 13x + -13x

Combine like terms: 7x + -13x = -6x
-6x = -15 + 13x + -13x

Combine like terms: 13x + -13x = 0
-6x = -15 + 0
-6x = -15

Divide each side by '-6'.
x = 2.5

Simplifying
x = 2.5

Answers

Answer:

slope is -3

y-intercept is 3

Step-by-step explanation:

Answer:

y-intercept: 3

Slope: -3

Step-by-step explanation:

y-intercept

To find the y-intercept, see what point on the y-axis (vertical bold line on the graph) the line passes through.

Slope

To find slope, find 2 points (from left to right) on the line and and put the height difference over the width difference in a fraction (simplify if possible). At points (0,3) and (1,0) there is a height drop of 3 (so -3) and a width of 1 and [tex]\frac{-3}{1}[/tex] gives you a slope of -3.

He is not correct, his mistake was multiplying 1/2 to 2x and 1, when you should have multiplied the negative to them.

Answer:

Thomas is not correct, x-2 is the correct answer

Thomas made his mistake by multiplying the 1/2 by both (6x-2) and -(2x+1). Thomas should have multiplied the 1/2 by just the (6x-2).

evaluate 36 / x + 9 when x equals 3

Answers

Answer:

Step-by-step explanation:

Given equation:

36 ÷ x + 9

Given variables:

x = 3.

Solve:

36 ÷ x + 9= 36 ÷ 3 + 9= 36 ÷ 12= 3.

36/x+9 = 3

Multiply all terms by x and cancel:

36+9x=3x

9x+36=3x
(Simplify both sides of the equation)

9x+36−3x = 3x−3x

(Subtract 3x from both sides)

6x+36 = 0
6x+36−36 = 0−36

(Subtract 36 from both sides)

6x = −36

6x/6 = −36/6

(Divide both sides by 6)

x = −6
