Teo makes a necklace of x wooden beads at .50 each and 6 glass beads at 1.25 each. The average cost of the beads in the necklace
1 answer:
For a necklace.
There are x wooden beads at $0.50 each.
There are 6 glass beads at $1.25 each
Therefore the cost of the beads in a necklace is
0.50x + 6*1.25 = 0.5x + 7.5 dollars
There are (x+6) beads. Because the average cost of the beads is $0.75, therefore
The solution for x may be obtained as follows:
0.5x + 7.5 = 0.75x + 4.5
-0.25x = -3
x = -3/-0.25 = 12
Answer:
The equation to find x is
(0.5x + 7.5) = 0.75(x + 6)
There are x wooden beads at $0.50 each.
There are 6 glass beads at $1.25 each
Therefore the cost of the beads in a necklace is
0.50x + 6*1.25 = 0.5x + 7.5 dollars
There are (x+6) beads. Because the average cost of the beads is $0.75, therefore
The solution for x may be obtained as follows:
0.5x + 7.5 = 0.75x + 4.5
-0.25x = -3
x = -3/-0.25 = 12
Answer:
The equation to find x is
(0.5x + 7.5) = 0.75(x + 6)

Answer:
0.7246 radians
Step-by-step explanation:
According to the Question,
Given that, a rectangle box has length 12 inches, width 15 inches, and a height of 17 inches
- The length of the base diagonal (d) can be found using the Pythagorean theorem on length and width:
d = √{ (12)² +(15)² } = √(144+225) = √369inches
- The tangent of the angle is the ratio of the height of the box to this length
Tan∅ = 17/√369
Taking the , we have
∅ = (17/√369) ≈ 0.7246 radians
Answer:
it must always have one of the sign
