Answer:
k= -0.2
Step-by-step explanation:
3+2(5k-3)=7 (original)
3+10k-6=7 (distribute 2 in (5k-3))
9+10k=7 (combine like terms 3+-6)
10k=-2 (subtract 9 on both sides to isolate k)
k=-0.2 (divide 10 on both sides to get you're answer/isolate k)
Answer: rate is a ratio that is used to compare different kinds of quantities. A unit rate describes how many units of the first type of quantity corresponds to one unit of the second type of quantity.
Answer:
No, Tina is not correct since 3.4 × 105 = 357 and 8.25 × 104 = 858
That is angle/360 times area
area=pir^2
r=12 in this one
and angle=60
so
60/360 times pi12^2=1/6 times 144pi=24pi square inches
-36° × π / 180°
= -0.2π rad
= -0.62831853072 rad hope this helps you
