Answer:
1300
Step-by-step explanation:
The number in the place to the right of the hundreds place is 5, in the tens place. That digit is greater than 4, so the rounding is to the next higher hundred: 1300.
180 degrees is the correct answer.
Answer:
36 ft
Step-by-step explanation:
13. y > 2
14. x - 13 < 9;; x < 22
15. x + 86 < 263;; at most 177 pounds
The total area of pool and border = 361 square feet.
Length of square pool = x
Length of square pool plus border = (x + 1 +1 ) = x + 2
There is 1 foot length on each side on the x length.
The other length of the square pool and border = (x + 2)
Area = (x+2)(x+2)
(x + 2)(x +2) = 361. Let A = x +2
A*A = 361
A² = 361 Take square root of both sides
A = √361
A = 19
A = x + 2 = 19
x = 19 - 2
x = 17
Area of square pool = x*x = 17*17 = 289
Area of the pool = 289 square feet.
