First look at √(60+n).  The first positive value of n that will make 60+n into a perfect square is 4, and √64 = 8.

Look at √(2n+28).  If n = 1, 2, 3, (2n+28) = 30, 32, 34, whose square roots are all irrational.  But if n = 4, we get √(2*4+28) = √36 = 6, which is rational.

An angle measures 22.8° more than the measure of its supplementary angle. What is the measure of each angle?
Step2247 [10]

1 supplementary angles equal 180 degrees.

Make an equation and solve:

X + x + 22.8 = 180

2x = 157.2

X = 157.2/2

X = 78.6

One angle is 78.6 degrees

The other angle is 101.4 degrees

Help asap giving branlist!!!
MA_775_DIABLO [31]

Answer:

Option 2

Step-by-step explanation:

The first statement is false because the price for 10 gallons is about $37 from the graph. Using this same reasoning, the third statement is also false. The last statement doesn't make sense because the graph has nothing to do with the amount of miles driven. Therefore, the answer is the second statement. We can prove it by looking at the point (4, 15). This means that it costs $15 for 4 gallons, so then the price for one gallon will be 15 / 4 = $3.75.
