Irrational numbers are numbers that can not be written<span> as a ratio of two integers. (example: square root of 2). Rational numbers on the other hand can be written as a ratio, as decimal or percentage.
If X is a irrational number, than the number Y=1-X is also irrational and the sum of these two irrational numbers is: X+Y=X+1-X=1 is rational number.
So, the sum of two irrational numbers can be a rational number. </span>

Answer: B. -0.5 blocks per minute
Step-by-step explanation: It goes up 2 on the x column and down 1 (-1) on the y column. So it would be -1/2 = -0.5.
1. The model is <span>14x19x11 centimeters. The ratio is 1 cm : 0.5 m.
14(0.5) = 7
19(0.5) = 9.5
11(0.5) = 5.5
</span>7x9.5x5.5 meters
b) 365.75 m^3
2. To find the money spent on food, all you do is find the percent of food of the total income. food = 35%, income = $2000
35% of 2000
0.35(2000)
a) $700
3. <span>4.8x-1.3=1.7
First add 1.3 to both sides to cancel it out.
4.8x = 3
Divide both sides by 4.8.
x = 0.625
</span><span>c) 0.63</span>
