Answer: 1 2/3 yards for each bow
Step-by-step explanation:
8 1/3 divided by 5 = 25/3 * 1/5 = 5/3
Answer:
27.5 m/s
Step-by-step explanation:
Average speed = distance / time
s = (2500 m + 3000 m) / (200 s)
s = 27.5 m/s
Note that average speed is different than the average velocity. Average velocity would be displacement over time, rather than distance over time.
220 cm2/s
EXPLINATION
L length of rectangel (cm)
W width of rectangel(cm)
A area of rectangel (cm²)
T time (s)
we are told that:
d1\dt=8cm\s(const),and dw\dt =3cm\s(const)
the area of the rectangel is
A=LW
Differentiating wrt t (using the product rule) we get;
dAdt=(l)(dwdt)+(dldt)(w)
∴dAdt=3l+8w
So when l=20 and w=10⇒
dAdt=3⋅20+8⋅20
∴dAdt=60+160
∴dAdt=220 cm2/s
-35 ÷ 7
-54 ÷ (-6)
3 ÷ (-1)
