Answer:

25.5   and   37.5

Step-by-step explanation:

x+y=63

x-y = 12    then   x = 12 + y      sub this into the first equation

(12+y)    + y = 63

12 + 2y = 63

2y = 51

y = 25.5     then x = 37.5

The endpoints of a diameter of a circle are (4,-2) and (3,6). Find the area of the circle in terms of pi
Vinil7 [7]
The endpoints of a diameter of a circle are (4,-2) and (3,6). The area of the circle in terms of pi is 65pi
First, is to get the length of the diameter by getting the distance of the two points: (4, -2) and (3, 6)

dis = sqrt( (x2-x1)^2 + (y2-y1)^2)
dis = sqrt( (3-4)^2 + (6--2)^2 )
dis = sqrt( 1 + 64 )
dis = sqrt(65)

Next, is to find the area of the circle:
A = pi * r^2
A = pi * (sqrt(65))^2
A = 204.20 square units

Stella [2.4K]

Answer:

Abby's mother spent $9.75 for the classroom not including tax.

Step-by-step explanation:

Know:

5 bags for 1 dollar

10 candy bars for 50 cents

3 whistles for 75 cents

5×6=30

10×3=30

3×10=30

  1. 5 times 6 is thirty. So find the product of 6 and 1 which is 6. 6 is the overall cost of bags.
  2. 10 times 3 is 30. So find the product of 3 and .50 which is 1.50. 1.50 dollars is the overall cost of candy bars.
  3. 3 times 10 is 30. You then find the product of 3 and .75. The product of this is 2.25 which is the total cost of whistles.
  4. Next you add all the values together which are 6.00 + 1.50 + 2.25 this equals $9.75
