Step-by-step explanation: Put all the numbers in a vertical format and add them all up
9.95
+1.15
+4.95
--------
16.05
We can let the radius of the semi circles be r and x can be the length of the rectangle.
The perimeter will be Perimeter = 2x + 2pr = 1200
The area of the rectangle is Area = x(2r)
Once we solve the perimeter equation, you get x = 600.
Put this into the area equation and you get Area = (600 - pr)(2r)
The maximum then gives r = 95. 493 and area 57, 295.8
Dimensions
Height is twice the radius or 190.986. Find base use equation x = 600 - p(95.493) = 300.
This means dimensions are 300 by 190.986
24 square units
because 8*3=24 square units
Answer:
23 is the prime number
Step-by-step explanation:
let n, n + 2, n + 4 be the consecutive odd numbers, then
n + n + 2 + n + 4 = 69 ← simplify left side
3n + 6 = 69 ( subtract 6 from both sides )
3n = 63 ( divide both sides by 3 )
n = 21 , then
n + 2 = 21 + 2 = 23 and n + 4 = 21 + 4 = 25
The 3 numbers are 21, 23, 25 with prime number 23
