Option B
Step-by-step explanation:
Not a unique triangle—the 10 cm side can be any of the three sides.
Step-by-step explanation:
it seems there are some mistakes with this text.
if I understand correctly, than she runs on a circular track with a radius of 79 ft for 126 ft.
and we need to find the angle of the arc (the part-circle) she was running.
for that we need to find the ratio arc length / circle circumference, and then multiply that with 360° (you know, a full circle represents 360°, one full turn around), and that will be the arc angle.
the circle circumference is
2×pi×r = 2×pi×79 = 496.3716393... ft
the arc angle is therefore
360 × 126 / 496.3716393 = 91.38314201...°
rounded to the nearest degree : 91°
Answer:
8
Step-by-step explanation:
mystery number= x
he divdes x by 2 and then subtracts 9 and gets -5. reverse the order to find x.
-5+9 which is 4 times 2 which is 8. x is 8
we have that
Part c)
the probability is equal to
P=0.14+0.27+0.58
<h2>P=0.99</h2>
because is the sum of
x=1, x=2 and x=3
Part D
the probability is
P=0.01+0.14+0.27
<h2>P=0.42</h2>
because is less than or equal 2
