Answer:
4 sqrt(3) =x
Step-by-step explanation:
Since this is a right triangle, we can use trig functions
sin theta = opp / hyp
sin 60 = x / 8
8 sin 60 = x
8 ( sqrt(3)/2) = x
4 sqrt(3) =x
Answer:
No solution
Step-by-step explanation:
This answer has no solution, follow these steps to see how.
First, you add 7 on both sides.
Then you should have 2b > -7 +2b
You see how there is a 2b on both sides? this makes the problem unsolvable.
Say you were to continue though. You would subtract 2b on both sides and end up getting 0 > -7. Therefore there is no solution.
Answer:
35x.40=14
Step-by-step explanation:
you multply $35 by .40 because that is the remaining cost from 60%
Answer:
The area of one of the bases is 0.96 ft²
The area of each lateral rectangular face is 4.8 ft²
The surface area of the paperweight is 6.72 ft²
Step-by-step explanation:
we know that
The surface area of the rectangular prism is equal to
SA=2B+LA
where
B is the area of one of the bases
LA is the lateral area of the prism
<em>Find the area of one of the bases B</em>
B=(0.8)(1.2)=0.96 ft²
<em>Find the lateral area LA</em>
The lateral area is the area of each lateral rectangular face
LA=2[(0.8)(1.2)]+2[(1.2)(1.2)]=4.8 ft²
<em>Find the surface area</em>
SA=2(0.96)+4.8=6.72 ft²
