Find Tan A if Cos2A = 1/2
Answer:
tan A = ± 1/√3 or ± 0.58
Step-by-step explanation:
2 ways to solve this question.
1. cos 2A = 1/2 2A = 60° or 300° or 420° or ....
A = 30° or 150° or 210° ....
tan A = tan 30° or tan 150° or ... = ± 1/√3
2. cos 2A = 2 cos²A - 1 1/2 = 2 cos²A - 1 cos²A = 3/4
cos 2A = 1 - 2 sin²A 1/2 = 1 - 2 sin²A sin²A = 1/4
tan²A = sin²a/cos²A = (1/4) / (3/4) = 1/3
tan A = ± 1/√3 or ± 0.58

Terry has 15 candles. She needs at least 100 candles. The candles she wants are sold in boxes of 8.
What is the least number of boxes of 8 candles that Terry needs to buy?
Answer:
11 boxes of candles
Step-by-step explanation:
first, set it up as an equation. let x stand for the amount of boxes she needs.
100=8x+15
next, subtract 15 from both sides of the equation.
100-15=8x+15-15
85=8x
then, you need to get x by itself. to do this, divide 8 from both sides of the equation.
85/8=8x/8
x=10.62, but you can't buy half a box, so you have to round up.
so, she needs to buy 11 boxes of candles.

Answer:
Volume of given figure = 113.12 cm²
Step-by-step explanation:
Given:
Radius of cylinder = 4/2 = 2cm
Radius of cone = 4/2 = 2 cm
Height of cylinder = 7 cm
Height of cone = 6 cm
Find:
Volume of given figure
Computation:
Volume of given figure = Volume of cylinder + Volume of cone
Volume of given figure = πr²h + (1/3)πr²h
Volume of given figure = (22/7)(2)²(7) + (1/3)(22/7)(2)²(6)
Volume of given figure = (22/7)(4)(7) + (1/3)(22/7)(4)(6)
Volume of given figure = (22)(4) + (22/7)(4)(2)
Volume of given figure = 88 + 25.14
Volume of given figure = 113.12 cm²

Answer:
B. 4x+5
Step-by-step explanation:
First, you multiply both sides by 4, then you have x=y-5. You then add 5 to get 4x+5
(in the very beginning, you switch the x and y so you would have to make the equation x= y-5 / 4 if that confused you)

The perimeter of the triangle below is 75 m. Determine the measure of each side of the triangle
Step-by-step explanation:
The perimeter is the sum of all sides.
AB+AC+CB=75
(2x-9) + (2x+3) + (3x+4) = 75
Combine like terms:
(2x+2x+3x) + (-9+3+4) = 75
7x - 2 = 75
7x = 77
x=11
Replace 'x' with '11' in the above equations to find that:
AB = 2(11) - 9 = 22 - 9 = 13 m
AC = 2(11) + 3 = 22 + 3 = 25 m
CB = 3(11) + 4 = 33 + 4 = 37 m
13 + 25 + 37 = 75 m

On a certain hot summer's day, 335 people used the public swimming pool. The daily prices are $1.25 for children and $2.00 for adults. The receipts for admission totaled $619.2. How many children and how many adults swam at the public pool that day?
Answer:
57
Step-by-step explanation:
Let c represent the number of children ($1.75 each) and a represent the number of adults ( $2.00 each).
We know that there were 340 people total, so c + a = 340. This implies that a = 340 - c
We also know that $1.75 c + $2.00 a = $609.25
By substituting a with 340 -c we have $1.75 c + $2.00 (340 -c) = $609.25
Use the distributive property to obtain $1.75 c + $680 - $2.00 c = $609.25
Subtract $680 from both sides and combine like terms to get - $0.25 c = -
$70.75
Now, divide both sides by -$0.25 to get c = 283, the number of children.
The number of adults is 340 - c or 340 - 283 = 57

2. How many distinguishable permutations are possible with all the
letters of the word ELLIPSES?
Answer:
5040
Step-by-step explanation:
This problem is about indistinguishable permutation. We have indistinguishable objects, in this case, these are the letter of the word ELLIPSES. The permutations for the word ELLIPSES is the same when you swap the places of the Ls. We need to not count them to avoid double counting.
We first count how many letters we have on the word, and then count the repeating letters.
ELLIPSES has 8 letters, 2 Es, 2Ls, and 2S.
The formula for indistinguishable permutation is
where n is the total number of objects and are the number of indistinguishable objects.
We have 2Es, 2Ls, and 2S; the formula then becomes:
Simplifying gives us
There are 5,040 distinguishable permutations of the word ELLIPSES.

The total 5040 distinguishable permutations are possible with all the letters of the word ELLIPSES.
The given word is ELLIPSES.
It is required to find total distinguishable permutations that are possible with the above word.
What is permutation?A permutation can be defined as the number of ways a set can be arranged.
Permutation formula as below:
[tex]P=\frac{n!}{p!q!r!...}[/tex]
Where n = Total number of objects.
p,q,r...= the number of indistinguishable objects.
Here total number of letters in the word n = 8
and ELLIPSES have 2Es, 2Ls, and 2S; the formula then becomes:
[tex]=\frac{8!}{2!2!2!}[/tex]
[tex]=\frac{8*7*6*5*4*3*2*1}{2*1*2*1*2*1}[/tex]
[tex]=5040[/tex]
Thus, the total 5040 distinguishable permutations are possible with all the letters of the word ELLIPSES.
