Marian is making accessories for the soccer team. She uses 888.44 inches of fabric on headbands for 36 players and 2 coaches. Sh
ki77a [65]

Answer:

23.38 inches of fabric was used for headband for each player.

9.43 inches of fabric was used for wristband for each player.

Step-by-step explanation:

Given that:

Total fabric used on headbands = 888.44 inches

Total number of players = 36

Total number of coaches = 2

Total number of people for whom headbands were made = Number of players + Number of coaches = 36 + 2 = 38

Amount of fabric used for each one = Total fabric used for headbands divided by Total number of people

Amount of fabric used for each one = \frac{888.44}{38}=\bold{23.38\ inches}

Similarly,

Total fabric used on wristbands = 339.48 inches

Total number of players = 36

Amount of fabric used for each one = Total fabric used for headbands divided by Total number of players

Amount of fabric used for each one = \frac{339.48}{36}=\bold{9.43\ inches}

Minnie organizes data in a table to show the net change in the number of people subscribing and unsubscribing to her blog each m
olchik [2.2K]

The factored expression which represents the net change in the number of blog subscriptions over 10 months is :

  • 3(11 - 7) + 4(-8)
  • Hence, the net change is -20

Change : -8, 11, -7, -7, -7, -8, -8, -8, 11, 11

To factor the values in the change variable :

-7 has a frequency of 3

-8 has a frequency of 4

11 has a frequency of 3

Values having the same frequency can be factored together :

Hence, we have ;

3(11 - 7) = 3(11 - 7) = 3(4) = 12 - - - - (1)

-8 having a value of 4 can be factored thus ; 4(-8) = -32 - - (2)

Joining both equations :

3(11-7) + 4(-8)

3(11 - 7) + 4(-8)

3(4) + 4(-8)

12 + (-32)

= - 20

Therefore, the factored expression for the net change in subscription is 3(11-7) + 4(-8)

Write the standard equation of a circle that passes through (-5 5) with center (-10 -5) brainly
timama [110]

Answer:

The equation of the circle is (x + 10)² + (y + 5)² = 125 in standard form

Step-by-step explanation:

* lets study the standard form of the equation of a circle

- If the coordinates of the center of the circle are(h , k) and its radius

 is r, then the standard equation of the circle is:

 (x - h)² + (y - k)² = r²

* Now lets solve the problem

∵ The coordinates of the center of the circle are (-10 , -5)

∵ The standard form of the equation is (x - h)² + (y - k)² = r²

∵ h , k are the coordinates of the center

∴ h = -10 , k = -5

∴ The equation of the circle = (x - -10)² + (y - -5)² = r²

∴ The equation of the circle = (x + 10)² + (y + 5)² = r²

- To find the value of the radius lets use the point (-5 , 5) to

  substitute their coordinate instead of x and y in the equation

∵ The circle passes through point (-5 , 5)

∵ (x + 10)² + (y + 5)² = r²

- Use x = -5 and y = 5

∴ (-5 + 10)² + (5 + 5)² = r² ⇒ simplify

∴ (5)² + (10)² = r²

∴ 25 + 100 = r²

∴ r² = 125

* Now lets write the equation in standard form

∴ (x + 10)² + (y + 5)² = 125

* The equation of the circle is (x + 10)² + (y + 5)² = 125 in standard form
