1pound is 800/560......which is 80/56-->10/7
so 1 pound is 10/7 dollars....
because you don't say for one dollar it is this many pounds.
also for unit rate i divide by 560 on both sides to get one pound on one side and then how many dollars on the other
Step-by-step explanation:
we know that:

using this, we can see that x = 73 and y = 13
using this, tan(x-y) = tan(73-13) = tan(60)
therefore, A = 60
we know that tan(60) = √3
therefore, B = 3
I would say (B)
Natural numbers are also whole numbers
Natural numbers start after 1, so {1,2,3,4,5....}
Whole numbers are numbers that are complete in itself and it includes 0 unlike natural numbers
Answer: second option
Step-by-step explanation:
The equation of the line in slope-intercept form is:

Where m is the slope and b is the y-intercept.
Rewrite the expression as:

Solve for "y":

You can identify that:

Therefore, the line intersects the y-axis at the point (0,10)
For the graphs of inequalities with
the line must be solid.
The inequality given is
and it can be written as 
Then, the shaded region must be above the solid line. Therefore it does not include the origin (Observe the graph attached).
Answer:
141.3 km
Step-by-step explanation:
First crater has the radius (that is, half the diameter) of 7.5 km; the circumference of this crater is C = 2(pi)r, or 2(3.14)(7.5 km) = 47.1 km;
Second crater radius is C = 2(pi)(30 km) = 188.4 km
The circumference of the complex (larger) impact crater is
(188.4 - 47.1) km greater than the circumference of the simple (smaller) crater:
141.3 km
