Answer:
N-12 = 20
N=32
Step-by-step explanation:
Difference means subtract, is means equals
N-12 = 20
Add 12 to each side
N-12+12 =20+12
N = 32
Answer:
6=x
5.375=y
Step-by-step explanation:
You add 57° and 37° together and get 94°
You subtract the 94° from 180° (the total of the angles for all triangles) and you get 86°.
So the third angle is 86°, but it is bisected, so you divide it in half.
43=7x+1
You subtract one from both sides, giving you 42=7x
you divide 42 by 7 and get 6, so x is 6.
You divide 8 by 43 to get y.
Answer:
46.37 square units
Step-by-step explanation:
If the right triangle is revolved the figure shown about the y-axis completely, the figure will be formed as a cone. As you can see in my attached photo.
So, the radius of the cone is : 2 units
the slant height is: = (use pytagon theory)
Hence, the total surface area of the resulting figure
SA = π * the radius * the slant height + π*
= 3.14*2* + 3.14*2*2
= 33.81 + 12.56
=46.37 square units
Answer:
2x
Step-by-step explanation:
2x2= 4
4+6x=10x
10x-8=2x
Than you multiplie tha 50 by 1/50 so will get 50/50 what is equal 1
hope this is understandably sure right easy
