I believe it is D(A hand grenade)
I hope this helps:)
Answer:
sample space { HH, HT ,TH ,TT}
Step-by-step explanation:
the possibilities are head and tails, H or T
so you can get heads heads, heads tails, tail heads or tail tails
A=-.25+6.7t, s=.75+4.5t when Amir catches up a=s so:
-.25+6.7t=.75+4.5t add .25 to both sides
6.7t=1+4.5t subtract 4.5t from both sides
2.2t=1 divide both sides by 2.2
t=10/22 hr
t≈0.45 hr (to nearest hundredth)
Suppose the triangle is labeled ABC. That is, angle A, angle B and angle C. The opposite sides for the respective angles are labeled a, b and c.
let a = 300, b = 250, c = 420
The smallest angle should correspond to the shortest side. So 36 degrees is angle B. Thus, we have sides a and c, with an included angle B. The area of the triangle is calculated as half of the products of the two sides with sine of the included angle.
Area = (a × c × sinB) / 2
Area = (300 ft × 420 ft × sin36) / 2
Area is 37,030 ft2.
Thus, the answer is letter C.
