Answer:
[tex] \frac{7}{25} [/tex]
Step-by-step explanation:
We can solve that using this identity,
[tex] \sin {}^{2} (x) + \cos {}^{2} (x) = 1[/tex]
plug in -24/25 from x in sin
[tex] \sin {}^{2} ( \frac{ - 24}{25} ) + \cos {}^{2} (x) = 1[/tex]
[tex] \sin( \frac{576}{625} ) + \cos {}^{2} (x) = 1[/tex]
[tex] \cos {}^{2} (x) = 1 - \frac{576}{625} [/tex]
[tex] \cos {}^{2} (x) = \frac{49}{625} [/tex]
[tex] \cos(x) = \frac{7}{25} [/tex]
Since cos is positve in quadrant 4, the answer is 7/25.
Answer:
Step-by-step explanation:
Use SOH CAH TOA to recall how the trig functions fit on a triangle
SOH: Sin(Ф)= Opp / Hyp
CAH: Cos(Ф)= Adj / Hyp
TOA: Tan(Ф) = Opp / Adj
then
Sin(Ф) = - [tex]\frac{24}{25}[/tex]
find the angle Ф
Ф = arcSin ( - [tex]\frac{24}{25}[/tex] )
Ф = -73.739795°
so an angle measured clock wise from x axis at zero°
now use cos(Ф) = x/ 25 to find x
25* cos( -73.739795°) = x
7 = x :o wow... exactly? :P nice
cos(Ф) = 7/25 I think that's what they wanted to know
also I noted my calculator tried to find the fraction of 0.2800000049 and couldn't, but then I just put in 0.28 and it found that to be 7/25 :0 so I think we're spot on :)

Pythagorean theorem: [tex]a^{2}+b^{2}=c^{2}[/tex]
Answer:
B
Step-by-step explanation:
Pythagorean theorem states that a²+b²=c²
Through observation, I assumed that 8 was the hypotenuse
I sqaured both the known lengths of the leg and hypotenuse and plugged them into the equation: a²+36=64
I subtracted 36 from 64 leaving me with 28=a²
Then in order to isolate the variable I had to apply square root to both values, cancelling the "²" and leaving me with √28=a
I couldn't find the answer

Suppose a video store charges nonmembers $4 to rent each video. A store membership costs $21 and members pay only $2.50 to rent each video. For what number of videos is the cost the same?
Answer:
You need to rent
14
videos, and you'll pay the same amount for both. Renting
15
will make the membership a better method of payment.
Explanation:
We can create an equation. Say the number of videos you rent is given by
n
. We can write that, if we rent
n
videos without membership, we'll have to pay
4
n
. If we rent the same amount of videos with membership, we'll have to pay
21
+
2.5
n
.
To find the value of
n
such that the amount you pay without membership is equal to the amount you pay with, we write:
4
n
=
21
+
2.5
n
1.5

Darius found that 16 out of 25 students in his class do not have a cell phone. What percent of students in his class do not have a cell phone?
Answer:
64%
Step-by-step explanation:
16/25=0.64
Answer: 64% of students do not own a cell phone
Step-by-step explanation:
First, take 100 and divide it by 25, since percentages are out of 100
100/25=4
Now multiply 4 by 16
4x16
You will get
64%
Jimmy Walked a total of 6 miles last week. This week, he walks 2 miles each hour. If he walks 6 hours this week, how many miles will he have walked in all?
Answer:
18 miles
Step-by-step explanation:
Find how many miles he walked this week by multiplying 2 by 6:
2(6)
= 12
Add this to 6, since he walked 6 miles last week:
12 + 6
= 18
So, in all, he will have walked 18 miles

If ξ={1 , 2 , 3 , . . . , 8 , 9 , 10}
A={x : x is multiples of 3},
B={x : x is a prime numbers} and
C={x : x<6},
then what is (A⋃B)ʹ⋂C ?
Answer:
{1,4}
Step-by-step explanation:
A={3,6,9}
B={2,3,5,7}
C={1,2,3,4,5}
AUB={2,3,5,6,7,9}
(AUB)'={1,4,8,10}
(AUB)'⋂C={1,4}
Answer:
Step-by-step explanation:
A = {3 , 6 , 9}
B = {2,3,5,7}
A ∪ B = { 2,3,5,6,7,9}
(A∪B)' - is set of all elements in universal set that are not in (A∪B)
(A∪B)' = {1,4,8,10}
C = {1,2,3,4,5}
(A∪B)' ∩C = {1 , 4}

Use the diagram to find the measures of all the angles, given that m<1 = 76º.
Answer:
m∠2 = 104°
m∠3 = 76°
m∠4 = 104°
Step-by-step explanation:
∠1 and ∠3 are vertical angles
That means they are of the same value.
∠2 and∠4 are also vertical angles and we can find the value like this:
Sum of all angles = 360°
Total value of found angles = 152°
Number of angles need to be found = 2x (note: this is 2x because both angles are the same)
Equation = 360 - 152 = 2x
208 = 2x
x = 208/2
x = 104
So angle m∠4 = 104°
and m∠2 = 104°
A bag contains 6 Purple sticks, 5 Orange sticks, 4 black sticks and you ask a friend to pick a stick at random. What is the probability that the stick will be purple?
And thx
Answer:
9 (partly to do with the amount of sticks)
Hope this helps :)
Answer:
[tex]\frac{2}{5}[/tex]
Step-by-step explanation:
probability (P) is calculated as
P = [tex]\frac{favourableoutcome}{numberofpossibleoutcomes}[/tex]
Here favourable outcome is a purple brick
number of possible outcomes = 6 + 5 + 4 = 15
P(purple brick ) = [tex]\frac{6}{15}[/tex] = [tex]\frac{2}{5}[/tex]

Maxine find a dress on sale for 10% off at a boutique.The original price was $62, Maxine must also pay 6.75% sales tax.What is the final cost of the dress?
10% off means she pays 90% of the original price. (100% - 10% = 90%)
62 x 0.90 = 55.80 the sale price of the dress is $55.80
Now add the tax by multiplying the sale price by 1 + tax rate:
55.80 x 1.0675 = 59.57
She paid $59.57
Answer:
10% off means she pays 90% of the original price. (100% - 10% = 90%)
62 x 0.90 = 55.80 the sale price of the dress is $55.80
Now add the tax by multiplying the sale price by 1 + tax rate:
55.80 x 1.0675 = 59.57
She paid $59.57

Your mom deposits $3500 into an account that pays 4.75% annual interest compounded continuously. How many years will it take for the amount of money in the account to reach $15,000? Just enter a numerical answer for the number of years rounded to the hundredth place.
Answer:
About 31 years
Step-by-step explanation:
Given data
Principal= $3500
Rate= 4.75%
Final amount= $15,000
Time=??
The expression for time on compound interest is
Calculate time, solve for t
t = ln(A/P) / r
substitute
Calculate time, solve for t
t = ln(15000/3500) / 0.0475
t= ln(4.2857)/ 0.0475
t= 1.4552/0.0475
t= 30.63 years
Hence it will take about 31 years
The total amount kate had left is 4.20$ after buying 7 pencils at p cents. Please explain how do I answer this question and find the value of p
Answer:
each pencil almost costs 83 cents which is the value of p
Step-by-step explanation:
Here most important data that the amount which Kate had before the purchase of pencils is missing.
For our convenience i am assuming Kate had $10 before the purchase of pencil.
Since, after purchase the left with Kate = $4.20
Therefore, amount spend on purchase of pencils = $10-$4.20 = $5.80
In $5.80 Kate purchased 7 pencils
Therefore cost of each pencil p = 5.80/7 = $0.8285 ≅ $0.83
Therefore each pencil almost costs 83 cents which is the value of p
