Answer:
Step-by-step explanation:
So if we compare to , we should see the most amount of factors of 2 that they have in common is 5 and the most amount of factors of 3 that they have in common is 5.
If you aren't sure on the number of factors of 2 and 3 they have in common you could write it all out:
So if I were able to circle each pair of 2's they had in common I would circle 5 pairs.
If were able to circle each pair of 3's they had in common I would circle 5 pairs.
Answer:
The common difference is 20
Step-by-step explanation:
Answer:
x = 45°
Step-by-step explanation:
"Isosceles" means the base angles are congruent: they both have the same measure, 45°. (The hypotenuse is the "base" for this isosceles triangle.)
The acute angles of a right triangle are complementary, so the third angle can also be found as 90° -45° = 45°.
Answer:
the actual answer is 20 units

Answer:
Step-by-step explanation:
This is the kind of problem that is most easily solved graphically, because the solution point coordinates give both the time and the altitude.
The attached graph shows the planes both arrive at the altitude of 7093 feet after 52 seconds.
__
The equations for altitude in feet (y) as a function of time in seconds (x) are ...
y = 3687 +65.5x . . . . . plane A
y = 5000 +40.25x . . . plane B
Subtracting the second equation from the first gives . . .
0 = -1313 +25.25x
x = 1313/25.25 = 52 . . . . . . . add 1313 and divide by the x-coefficient
y = 3687 +65.5(52) = 3687 +3406 = 7093
After 52 seconds both planes have an altitude of 7093 feet.
