Step-by-step explanation:
It depends what the x is, lets say it is $16, then the discount price will be $20
Tip: if you need this again, just use Original Price Calculator for C. and Percent Off Calculator for A. and B.
Answer:
1.6 times per second
Step-by-step explanation:
You just have to divide 96 by 60 like this:
96÷60=1.6
Volume=(W)(H)(L)
ANSWER= 0.56
Answer:
a) The tree is 18 feet tall
b) No, 18 feet is less than 20 feet
Step-by-step explanation:
See attached picture as part of the solution.
a)
Let the tree height be X
The total Triangle ABC has been Interpreted from illustration.
Use the smaller triangle to find "Angle B"
Tan B = Opposite (6 ft) / Adjacent (10 ft)
Tan B = 0.6 ft
B = Tan⁻¹(0.6)
B = 30.9°
Since the smaller and bigger triangle has the same base angle B
∴ Tan 30.9° = X / 30
0.6 = X / 30
Multiply both sides by 30
0.6 x 30 = X
X = 18 ft
∴ The tree is 18 feet tall.
b)
The distance of the pole from the tree is 20 feet and the tree height is 18 feet. When the tree falls, the tree will not hit the pole because the length of the tree is shorter than the distance of the pole from the tree.
The given data contains points which are 1/5, 1/25, 1/125, and 1/625. From these we are able to conclude that the given is a geometric sequence with r equal to 1/5 and the first term is equal to 1/5. The sum of these term can be computed as,
S = a1/(1 - r)
Solving,
S = ((1/5)/(1 - 1/5) = 1/4
Thus, the sequence is convergent because the sum is a finite number.
