Answer:
1071.2
Step-by-step explanation:
Thousand is 1000
look at previous digit
8
8>5 so round up
533,000 is rounded
2 consecutive odd integers.....x and x + 2.....the product means multiply....the sum means add.
x(x + 2) = 4(x + x + 2) - 1
x^2 + 2x = 4(2x + 2) - 1
x^2 + 2x = 8x + 8 - 1
x^2 + 2x = 8x + 7
x^2 + 2x - 8x - 7 = 0
x^2 - 6x - 7 = 0
(x - 7)(x + 1) = 0
x - 7 = 0 x + 2 = 7 + 2 = 9
x = 7
x + 1 = 0 x + 2 = -1 + 2 = 1
x = -1
there can be 2 answers for this....
(1) 7 and 9
(2) -1 and 1
The tank is filling at
the rate of (58-36) in/(5-3 h) = 22/2 = 11 in/h.
72-58 = 14 inches more
to fill
<span>
The remaining 14 inches will be filled in
14 /11 = 1.27 , round to 1.3 hours</span>
so total time
would be 5 +1.3 = 6.3 hours
<h3>
Answer: choice B) counterclockwise rotation of 90 degrees around the origin</h3>
To go from figure Q to figure Q', we rotate one of two ways
* 270 degrees clockwise
* 90 degrees counterclockwise
Since "270 clockwise" isn't listed, this means "90 counterclockwise" is the only possibility.
