S = D/t
120 = D / 0.5
D = 120*0.5
D = 60 km
S = D/t
70 = D / 2.5
D = 70*2.5
D = 175 miles
Answer:
A.
Step-by-step explanation:
x-2y=4 has a x-intercept of 4, a slope of 1/2, and a y-intercept of -2. 2x+y=4 has a x-intercept of -2, a slope of 2, and a y-intercept of -4.
Would it be 72 because it’s 12 times 6
If you would like to eliminate the z-term, you can do this using the following steps:
x + z = 6 /*(-2)
3x + 2z = 1
_____________
-2x -2z = -12
<span>3x + 2z = 1
</span><span>_____________
</span>-2x + 3x = -12 + 1
x = -11
The correct result would be <span>x + z = 6 /*(-2).</span>
Answer:
Part I : 2160°
Part II : 165°
Part III : 36 sides.
Part IV : 10 sides.
Step-by-step explanation:
Part I : If the polygon has 14 sides, then the sum of all the interior angles of a polygon will be = (14 - 2) × 180° = 2160°. (Answer)
Part II : If the polygon has 24 sides, then the sum of all the interior angles of a polygon will be = (24 - 2) × 180° = 3960°.
Therefore, the measurement of each interior angles will be = . (Answer)
Part III : Given that 10° is each exterior angle of a polygon. So, each interior angle is (180 - 10) = 170°.
If the number of sides is n, then,
⇒ 10n = 360
⇒ n = 36 sides. (Answer)
Part IV : Sum of the all interior angles is 1440°.
If it has n sides, then (n - 2) \times 180 = 1440
⇒ n - 2 = 8
⇒ n = 10 (Answer)
