8 0

Answer:

99 marks

Step-by-step explanation:

Let 'x' be the mark in final exam

Sum of all the data's/ Number of data's = Mean

\frac{65+83+93+x}{4}=85\\\\\\\frac{241+x}{4} = 85

241 + x  = 85*4

241 + x = 340

       x = 340 - 241

x = 99

A circle has an area of 225pift2 find the radius of the circle and find the diameter and circumference of the circle
RideAnS [48]

Answer:

  • radius: 15 ft
  • diameter: 30 ft
  • circumference: 30π ft

Step-by-step explanation:

The area is given in terms of the radius as ...

  A = πr^2

so we can find the radius as ...

  r = √(A/π)

For your circle, the radius is ...

  r = √(225π ft^2/π) = 15 ft

The diameter is twice the radius, so is ...

  d = 2r = 2·15 ft = 30 ft

And the circumference is π times the diameter:

  C = πd = π·30 ft = 30π ft

Find the slope of the line through the pair of points. A(2, –3), P(2, 9)
Flauer [41]
The slope: m=\dfrac{y_2-y_1}{x_2-x_1}

A(2;-3)\to x_1=2;\ y_1=-3\\P(2;\ 9)\to x_2=2;\ y_2=9\\\\subtitute:\\\\m=\dfrac{9-(-3)}{2-2}=\dfrac{12}{0}!!!

<span>The denominator can not be <span>zero!

Conclusion: The slope is undenfined.

An average soccer player travels 7 miles during a game. A typical field is 104 meters long. How many times did the average socce
marissa [1.9K]

Answer:

About 108 times

Step-by-step explanation:

Given:

An average soccer player travels 7 miles during a game

A typical field is 104 meters long.

To find:

How many times did the average soccer play travel the length of the field?

Solution:

An average soccer player travels during the game =  7 miles

First convert 7 miles into meters,  1 mile = 1609.34 meter

                                                        7 mile = 1609.34 \times 7 = 11265.41 m

Length of field = 104 meters

To find number of times average soccer player travel the length of the field, we will divide an average soccer player travels during the game by Length of field

11265.41 m \div 104  = 108.32

Therefore, about 108 times average soccer player travel the length of the field
