Answer:
The rock formation is approximately 7 feet tall.
Step-by-step explanation:
<em>We can visualize this situation as a triangle and know that the bottom side is </em><em>10</em><em> and the angle of elevation (the angle created by Mike and the ground, looking to the top of a rock). With this information, we can use tangent to solve.</em>
<em>x = the height of the rock formation</em>
tan(22°) = x/10
10 tan(22°) = x
x = ~4.04 feet
<em>We also have to add the </em><em>3 feet</em><em> to it because it is being measured 3 feet above the floor.</em>
x + 3 = 7.04 feet
Answer:
25 x 40 = 1000
1210 - 1000 = 210
210 / 45 = 4.66 hours
Step-by-step explanation:
12q+3r=15
-4q-4r=-44
-4q=-44+4r
q=11-r
12(11-r)+3r=15
132-12r+3r=15
132-9r=15
117=9r
r=13
-4q-4(13)=-44
-4q-52=-44
-4q=8
q=-2
Answer:
−3b−6x+2
Step-by-step explanation:
2x+4−7−3b+5−8x
=2x+4+−7+−3b+5+−8x
Combine Like Terms:
=2x+4+−7+−3b+5+−8x
=(−3b)+(2x+−8x)+(4+−7+5)
=−3b+−6x+2
