Answer:

C\approx 5.14

Step-by-step explanation:

The circumference is the distance around a complete circle: in essence, the perimeter of a circle. The formula to find the circumference of a circle is the following:

C=(d)(\pi)

Where (d) represents the diameter, the largest cord that can be drawn in a circle, it goes from one end to another, passing through the center of the circle. The parameter (\pi) represents the number (3.1415...). However, one is given a semicircle, thus one must divide the result in two, and then add the value of the diameter to find the perimeter of the given object. Therefore the equation for the circumference of this circle is as follows:

C=\frac{(d)(\pi)}{2}+(d)

Substitute in the given value,

C=\frac{(2)(3.1415)}{2}+(2)

Simplify,

C=3.1415...+2

C=5.1415

C\approx 5.14

ann pays 300 for membership to a local gym. she is allowed to bring one guest on any visit. John pays Ann 5 to go to the gym wit
klemol [59]

Answer:

The expression represents Ann's membership cost as a function of how many times she brings John along. For t = 5 the cost is 275, for t = 10, the cost is 250 and for t = 20 the cost is 200.

Step-by-step explanation:

The expression "300 - 5*t" represents the cost of Ann's membership plan on the local gym, where "t" is the number of visits John pays Ann. This means that the more times John goes to the gym with Ann, the less is her cost to pay the membership.

For t = 5:

cost = 300 - 5*t\\cost = 300 - 5*5 = 275

For t = 10:

cost = 300 - 5*t\\cost = 300 - 5*10 = 250

For t = 20:

cost = 300 - 5*t\\cost = 300 - 5*20 = 200

Write an equation of the line that passes through the given points: (9/2,1), (-7/2,7) please show step by step how to do this. T
Viktor [21]

Explanation:

The easiest way to do this is to make use of the 2-point form of the equation for a line. For points (x₁, y₁) and (x₂, y₂), the equation is ...

  y=\dfrac{y_2-y_1}{x_2-x_1}(x-x_1)+y_1

Filling in your given points, the equation becomes ...

  y=\dfrac{7-1}{\frac{-7}{2}-\frac{9}{2}}(x-\frac{9}{2})+1

After you fill in the values, it is a matter of simplifying the resulting equation.

y=\dfrac{6}{\frac{-16}{2}}(x-\frac{9}{2})+1=\dfrac{-12}{16}(x-\frac{9}{2})+1=-\dfrac{3}{4}x+\left(\dfrac{-3}{4}\cdot\dfrac{-9}{2}\right)+1\\\\y=-\dfrac{3}{4}x+\dfrac{27+8}{8}\\\\y=-\dfrac{3}{4}x+\dfrac{35}{8}

I will give you brainliest please help me with this it’s for my finals please <3
Licemer1 [7]

Answer:

A = 125, B = 55, C = 125

Step-by-step explanation:

A line that is cut into two by a line has two angles that equal 180.  So angle A + angle D is 180. Angle D = 55 so 180 - 55 = 125. You do the same for every angle but look at the line as being cut into two in different directions for angles a and b and angles c and d.
