Answer:
671080887.6
Step-by-step explanation:
1 second = 300,000km
3600 seconds = 3600 x 300,000 = 1080000000 km then convert to miles
is 671080887.6

Answer:
2x - y = 0
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
y = 2x - 1 ← is in slope- intercept form
with slope m = 2
Parallel lines have equal slopes, thus
y = 2x + c ← is the partial equation
To find c substitute (1, 2) into the partial equation
2 = 2 + c ⇒ c = 2 - 2 = 0
y = 2x ← equation in slope- intercept form
Subtract y from both sides
0 = 2x - y , that is
2x - y = 0 ← equation in standard form
The pythagorean theorem is a^2 + b^2 = c^2, with c^2 being the hypotenuse (or longest side).
So a^2 + b^2 = 26
Since we're dealing with a triangle that was cut from a square, we also know that sides a and b are the same length. So, we can simplify our equation:
2a^2 = 26
Next, try to get a by itself, first by dividing both sides by 2 and then taking the square root of both sides:
a^2 = 13
a = the square root of 13
So, the side length of each piece will be the square root of 13 (approximately 3.5 inches).
Answer:
2b - 15
Step-by-step explanation:
b - 7 + b - 8
You combined the two b's correctly, but didn't combine the two constants, -7 and -8.
Those combine to -7 + (-8) = -7 - 8 = -15, so the final answer is
2b - 15
you have -7 and are subtracting 8 more, so you are moving 8 units left on the number line, so it has to get more negative.
