Answer:
37/8 (fraction) or 4.625 (decimal) or 4 5/8 (mixed number)
Step-by-step explanation:
Answer:
B
Step-by-step explanation:
Not easy to graph but
multily first equaiton by -2 remember to flip sign
-2x+4y>-6
add to other equaiton
2x-2x+y+4y>-6+8
5y>2
divide by 5
y>2/5
subtitute
2x+2/5>8
subtract 2/5 from both sdies
2x>7 3/5
divid eby 2
x>38/10=19/5=3 4/5
x>3 4/5
y>2/5
just shade the area in that zone, not including point (0,0)
Answer:
3/10,1/2,4/5
this is because
if you make them all have common denominators they are:
8/10, 3/10, and 5/10
and you put them in order based on their numerators
Answer:
27.2m
Step-by-step explanation:
First, I drew a diagram (see below). I realized that I was dealing with two triangles: one using the angle of depression and the other using the angle of elevation. I then got as much information as I could by solving for the third unknown angle at each triangle. Now, I solved using law of sines for the leg of the triangle that correlated to the height of the building. I used the law of sines because I had two angles and one side. I then added the two lengths of the legs to get the height of the building.
