solve for x. im pretty confused on how to do this i thought it was 60 but i was wrong
Answers
Answer: x = 12
Step-by-step explanation:
You're on the right track! You're right in saying that each angle has to be 60 degrees since they're supposed to add up to 180. However, the question is asking what x equals, so we set up the equation:
5x = 60
x = 12

At a zoo, the lion pen has a ring-shaped sidewalk around it. The outer edge of the sidewalk is a circle with a radius of 11 m. The inner edge of the sidewalk is a circle with a radius of 9 m.
(a) Write and simplify an expression for the exact area of the sidewalk.
(b) Find the approximate area of the sidewalk. Use 3.14 to approximate π.
Answers
A) Area of the sidewalk = R^2 - r^2 - This can be the expression
B) = 3.14
=(R^2-r^2)
=(11^2-9^2)
=(121-81)
=*40
That was the simplified expression
Answer = 3.14 * 40 = 125.6m^2

Find an equation of the tangent line to the curve at the given point. y=√x, (49,7) To find the equation of a line, we need the slope of the line and a
Answers
Answer:
The equation of the tangent line to the curve at the given point is [tex]y = \frac{1}{14}(x - 49) + 7[/tex]
Step-by-step explanation:
Equation of the tangent line:
The equation of the tangent line to a function f(x) at a point [tex](x_0,y_0)[/tex] is given by:
[tex]y - y_0 = m(x - x_0)[/tex]
In which m is the slope, which is given by the derivative of f(x) at [tex]x_{0}[/tex]
y=√x, (49,7)
This means that [tex]x_0 = 49, y_0 = 7[/tex]
The derivative is:
[tex]y^{\prime} = \frac{1}{2\sqrt{x}}[/tex]
At [tex]x = 49[/tex]
[tex]m = y^{\prime} = \frac{1}{2\sqrt{49}} = \frac{1}{14}[/tex]
So
[tex]y - y_0 = m(x - x_0)[/tex]
[tex]y - 7 = \frac{1}{14}(x - 49)[/tex]
[tex]y = \frac{1}{14}(x - 49) + 7[/tex]
The equation of the tangent line to the curve at the given point is [tex]y = \frac{1}{14}(x - 49) + 7[/tex]
Chila is measuring a triangle. First, she measures the triangle's angles. Each of the triangle's angles is 60 degrees. Next, she measures its sides. Side A is 6 cm long. Side B is also 6 cm long. What is the length of side C?
Answers
Answer:
Side C is also 6 cm long.
Step-by-step explanation:
Given: Each of the triangle's angles is 60 degrees.
Also, side A is 6 cm long. Side B is also 6 cm long.
To find: length of side C
Solution:
A triangle in which each angle is equal to 60 degrees is an equilateral triangle.
As each of the triangle's angles is 60 degrees, the given triangle is an equilateral triangle.
Sides of an equilateral triangle are equal to each other.
As side A is 6 cm long and side B is also 6 cm long,
side C is also 6 cm long.

A measurement of 4.5 yards is how many feet longer than a measurement of 132 inches?
Answers
Answer:
4.5X3=13.5, 132/12=11, 13.5-11=2.5
Step-by-step explanation:
A measurement of 4.5 yards is 2.5 feet longer than a measurement of 132 inches.
As we know that,
[tex]1 yard = 3 feet[/tex]
So, 4.5 yards = [tex]3*4.5=13.5feet[/tex]
[tex]12 inch = 1 feet\\\\132inch = \frac{`132}{12}=11feet[/tex]
Difference between 4.5 yards and 132 inches = [tex]13.5-11=2.5feet[/tex]
Thus, the measurement of 4.5 yards is 2.5 feet longer than a measurement of 132 inches.

The rectangle below has an area of x2 – 6x – 7 square meters and a width of x– 7 meters.
What expression representsthe length of the rectangle?
Answers
Answer:
The length is (x+1)
Step-by-step explanation:
We know the area equals length times width. LxW=Area
We know the width equals (x-7). We also know the area equals x² - 6x - 7.
We need to expand the area. When we do, we get (x+1)(x-7).
The width is (x-7), so the length must be (x+1)
