after a tourist covers 36% of the lenght of a route, he notices that he still has 240 km to park. What is the length of the route?
Answer:
375km
Step-by-step explanation:
The tourist has already covered 3% of the journey.
So the remaining distance to be covered is 64% f the total journey.
(100% - 36% = 64%)
Therefore 64% of the journey = 240km
Then 100% of the journey:
y km --> 100%
240 km --> 64%
Total length of the route = 240 km * (100/64) = 375km
If x = 9 and y = -3, evaluate the following expression: = 6x - 8y
Answer: 78
Step-by-step explanation:
Step 1:
Substitute the variables in:
6(9) - 8(-3)
Step 2:
Multiply to get rid of the parentheses:
54 - -24 = 54 + 24 (the two negatives cancel out)
Step 3:
Add, and then you're done:
54 + 24 = 78

The quotient of the provided fractional number is equal to the option D which is,
[tex]-2x^9[/tex]
What is the quotient?Quotient is the resultant number which is obtain by dividing a number with another. Let a number a is divided by number b. Then the quotient of these two number will be,
[tex]q=\dfrac{a}{b}[/tex]
Here, (a, b) are the real numbers.
The fraction given in the problem is,
[tex]\dfrac{-8x^6}{4x^{-3}}[/tex]
Let the quotient of the above function is q. Thus,
[tex]q=\dfrac{-8x^6}{4x^{-3}}[/tex]
In a fraction number, a negative power of a number in the denominator can be written with a positive number in the numerator and vise versa. Thus,
[tex]q=\dfrac{-8x^6(x^3)}{4}\\q=-2x^{6+3}\\q=-2x^9[/tex]

Roderigo has just finished paying back his $8,575 unsubsidized Stafford loan, which he took out to fund his four-year degree. The loan had a duration of ten years and an interest rate of 7. 1%, compounded monthly. Roderigo will allow interest capitalization. If Roderigo made monthly payments to pay off his loan, how much interest did he pay in total? Round all dollar values to the nearest cent. A. $4,547. 02 b. $3,426. 20 c. $7,353. 80 d. $5,436. 20 Please select the best answer from the choices provided A B C D.
Roderigo will pay $7353.80 in interest.
Interest capitalization means the interest earned is added to the principle amount so first we will use compound interest formula.
What is the formula for compound interest?[tex]Amount=p(1+\frac{r}{n} )^{nt}[/tex]
p = 8575
r = 7.1% or 0.071
n = 12
t = 4
Putting the values in formula we get
[tex]Amount=8575(1+\frac{0.071}{12} )^{12(4)}[/tex]
[tex]Amount=8575(1+\frac{0.071}{12} )^{48}[/tex]
Solving this we get;
Amount = $11381.94
For the next part we have EMI formula as,
[tex]EMI=\frac{pr(1+r)^{n} }{(1+r)^{n-1}}[/tex]
p = 11381.94
[tex]r=\frac{7.1}{\frac{12}{100} }=0.005917[/tex]
[tex]n=(12)(10)\\n=120[/tex]
[tex]EMI=\frac{11381.94(0.005979)(1+0.005979)^{120} }{(1+0.005979)^{120}-1}[/tex]
EMI = $132.74
Now total payments made in 120 months (10 years) =
[tex]132.74(120)=15928.80[/tex] dollars
interest paid =
[tex]15928.80-8575=7353.80[/tex] dollars
Hence, Roderigo will pay $7353.80

Three students are playing a video game. Each player is randomly
assigned a character from a collection of characters that includes
5 blue, 6 green, and 3 red characters. After each character is picked,
it is not replaced in the collection.
A. What is the probability that the first player does not get a blue character?
B. The first player gets a blue character. What is the probability that the
second player also gets a blue character?
C. Both the first and second players get blue characters. What is the
probability that the third player does not get a blue character?
Answer: B: 4/13, C: 3/4
B:
There were originally a total of 14 characters (including 5 blue characters) from the collection. Since the first player got a blue character, there are now 13 characters to choose from and 4 of them are blue. Therefore, the probability is 4/13.
C: If both the first and second players get blue characters, then there will be 12 characters left, and 3 of them are blue. Now we know that there are 9 characters that are NOT blue. Therefore, the probability is 9/12, or 3/4.

C) a n = 8n − 23
D) a n = −8n − 23
Answer:
C
Step-by-step explanation:
A) a(n) = 8n - 15
this is incorrect because if n = 3, then a = 9 not 1.
B) a(n) = -8n-15
this is incorrect because if n = 3, then a = -39 not 1.
C) a(n) = 8n-23
this is correct because if n = 3, then a = 1, and if n = 9, then a = 49.
D) a(n) = -8n-23
this is incorrect because if n = 3, then a = -47 not 1.

Cyclic Quadrilateral
A cyclic quadrilateral has all it vertices on the circumferences of the circle . opposite angle of a cyclic quadrilateral add up to 180 degrees. The sum of the whole angles add up to 360 degrees. Therefore, tha angle measure of each inscribed quadrilateral is as follows
10.
5x + 20 + 7x - 8 = 180
12x + 12 = 180
12x = 180 - 12
12x = 168
x = 168 / 12
x = 14
Therefore,
∠P = 5x + 20 = 5(14) + 20 = 90°∠R = 90°∠Q = 10x = 10(14) = 140°∠S = 40°11.
4z - 10 + 10 + 5z = 180
9z = 180
z = 20
Therefore,
∠A = 4z - 10 = 4(20) - 10 = 70°∠C = 110°∠ B = 6z - 5 = 6(20) - 5 = 115°∠D = 55°12.
1 / 2 z + 1 / 4 z + 30 = 180
3 / 4 z + 30 = 180
3 / 4 z = 150
3z = 600
z = 600 / 3
z = 200
Therefore,
∠B = z / 2 = 200 / 2 = 100°∠D = z / 4 + 30 = 200 / 4 + 30 = 80°∠E = z - 59 = 200 - 59 = 141°∠C = 39°13.
15y - 4 + 12y - 5 = 180
27y = 180 + 9
y = 189 / 27
y = 7
14 + 4x + 6x - 14 = 180
10x = 180
x = 18

Rita borrowed $7500 at an interest rate of 3%. The interest paid is $1462.50. For how many years did she borrow the money?
Answer: 6.5 years
Step-by-step explanation:
the formula for simple interest is:
SI = PRT, SI is the interest after a time, P is the principle amount, R is the rate, and T is the time passed
In our case:
1462.50 = 7500 x 0.03 x T
Solving for T:
1462.50 = 225T
.: T = 1462.50/225 = 6.5 years
