6 0

Step-by-step explanation:

you would take 45 and divide it by 3 which would give you what one witch = 15

take 21 divide it by 3 which gives you one wand =7

take the brooms and divide it 12 by 3 one broom = 3

then take the wand(15) and multiply is but the wand (7) =105

take 105 and add the broom too it(4) = 109

Locate the mean of 2046,971,3113,and 1850.
Debora [2.8K]
To find the mean, you have to add all the numbers then divide it by how many numbers there are.

In this case, you'll need to add all those numbers and divide it by 4.
2046+971+3113+1850=7980\\7980\div4=1995

The mean is 1995.

In a certain clothing store, 4 shirts and 6 ties cost $70, and 2 shirts and 4 ties cost $42. What is the cost of each tie?
Oksanka [162]

Answer:

  $7

Step-by-step explanation:

Your two equations are ...

  • 4s +6t = 70
  • 2s +4t = 42

Double the second equation and subtract the first:

  2(2s +4t) -(4s +6t) = 2(42) -(70)

  2t = 14 . . . . . simplify

  t = 7 . . . . . . . divide by 2

The cost of each tie is $7.

A square park with sides 15 meters in length has a diagonal walkway as shown.
Alexxandr [17]

Answer:

The approximate length of the diagonal walkway is 21.21 meters

Step-by-step explanation:

we know that

Applying the Pythagorean Theorem in the square park, find out the the approximate length of the diagonal walkway

so

c^2=a^2+b^2

where

c is the diagonal of the square

a and b are the length sides of the square

we have

a=15\ m\\b=15\ m

substitute

c^2=15^2+15^2\\c^2=450\\c=21.21\ m

therefore

The approximate length of the diagonal walkway is 21.21 meters
