Answer:
x = 2
Step-by-step explanation:
3(x+4)=18
3x + 12 = 18
3x = 6
x = 2
32/60 =
32 ÷ 60 ≈
0.533333333333333 =
0.533333333333333 × 100/100 =
0.533333333333333 × 100% =
(0.533333333333333 × 100)% ≈
53.333333333333% ≈
53.33%;
Figure out the weight of the glass by first figuring out the area of the sides.
There are four sides. Each side is a triangle with height 2ft and base 2ft. So the area of one of the triangles is 2 ft^2.
There are four sides, so there is a total of 8 ft^2. Each ft^2 weighs 2.45 pounds, for a total of 8*2.45 = 19.6 pounds
Since the chain can support up to 35 pounds, then the chain can support the light cover easily.
Given :
Plan A will cost $2.00 per song. Plan B will require a $15 joining fee and $1.49 per song.
To Find :
When will Plan A be a less expensive option for Aubrey? When will Plan B be a less expensive option for Aubrey?
Solution :
Let, after x songs Plan A will be less expensive.
So,
2x < 15 + 1.49x
0.01x < 15
x < 29.41 i.e x < 30
Before, 30 songs Plan A will be less expensive.
After, 30 songs Plan B will be less expensive.
Hence, this is the required solution.
Answer:
2)These two triangle are congruent because they have same shape and size.
1)it is explained already.
