geometry -someone help me do this thx

Answer:

Base on the picture, if there are no other choices beside A,B,C then the correct answer would be C. The picture only shows the first two pairs of x and y and they are both proportional, but I'm unsure about the rest of the pairs in C because the picture got cut off.

A and B are incorrect because they do not represent a proportional relationship between x and y. If there are no other choices, then C would be more correct than A and B.

Hope this helps :)

Answer:

4 7/15

Step-by-step explanation:

To subtract two fractions we need to have them have the same division by, which means the lower part of the fraction needs to be the same. To do that we would need to find a common denominator between 3 and 5, a number that can be both divided by 3 and 5. To figure common denominator for 5 and other nimbery just multiply the other number by 5: 3*5=15. so now we need to multiply both fractions by a number to get lower part to 15, so 4*3/5*3=12/15 and 1*5/3*5=5/15. Now we have 6 12/15 - 2 5/15 = 4 7/15.

Answer: k(x)=-4x+63

Step-by-step explanation:

Perpendicular slopes are opposite reciprocals of each other.

(1/4)^(-1)=4

4*(-1)=-4

k(x)=4x+b

k(-20)=4(-20)+b

-17=4(-20)+b

-17=-80+b

b=63

k(x)=-4x+63

Answer:

10 as 9 hundreds is 9 thousand.

Step-by-step explanation:

The digit is 9 thousand which can be written as 9,000

It can also be written as,

9,000 = 9 x 1000

or ,9,000 = 9 x 10 x 100

So, to require 9 hundreds multiply 9 by 100 in the expression above

9,000 = 10 x 900

And so Ten as 9 hundreds are 9 thousand.

If Tito took a loan of $10000 from a bank to be repaid within 4 years, at 12% Simple interest per annum, then, he will have to pay overall $4800 as interest to the bank over 4 years and a total payment of $14800 at the end of the 4th year to repay and close off the loan.

As per the question statement, a bank charges 12% Simple interest per annum on cash loans to its clients and Tito took a loan of $10000 from the same bank to be repaid within 4 years.

We are required to calculate the overall interest Tito has to pay to bank if he repays and closes the loan at the end of 4th year, and also to calculate the total payment required to repay and close off the loan at the end of the 4th year.

To solve this question, we need to know the formula to calculate the interest amount in case of simple interest which goes as

Interest (I) [tex]=(\frac{P*R*T}{100} )[/tex]

where, "P" = Principle amount of Loan,

"R" = Rate of simple interest charged on the principle per annum, and

"T" = Time period within which, the loan is to be repaid.

Here, (P = 10000), (R = 12%) and (T = 4). Then, the overall interest Tito will have to pay at the end of 4th year  = [tex](\frac{10000*12*4}{100}) = (100*12*4)=(48*100)=4800[/tex]

And total amount to be paid to repay and close of the loan at the end of 4th year will be = $[4800 + 10000] = $14800.

Step-by-step explanation:

The cost of the lab per hour is $25.

Here we know that they charged a total of $249.75, and the cost in parts was $181, then the cost in labor is:

$249.75 - $181 = $68.75

And we know that they worked for 2.75 hours, the cost per hour is given by the quotient between the cost in labor and the number of hours, then we can get:

$68.75/2.75 = $25

So we can see that the cost of the lab per hour is $25.

Answer:

14 videos

Step-by-step explanation:

4n=21+2.5n

1.5n=21

n=21/1.5

n=14

Answer:

14 Videos

Step-by-step explanation:

Let x be the number of videos rentable.

From the information given from the question, we know that:

Case A: Non-members

Cost to rent videos = $4x

Case B: Members

Cost to rent videos = $(21 + 2.5x)

So given from the question, we can use:

4x = 21 + 2.5x to solve for x.

[tex]4x = 21 + 2.5x \\ 4x - 2.5x = 21 + 2.5x - 2.5x \\ 1.5x = 21 \\ x = \frac{21}{1.5} \\ = 14[/tex]

The exponential growth model for the future population is given as [tex]y = 1500(1.1)^{t}[/tex]   and the student population after 7 years is 2923.06.

The general expression for the exponential growth is given as :

                       [tex]y = a(1+r)^{t}[/tex]

where, a  = initial amount or current student population of Philadelphia

           r = rate

           t = time in years.

According to the question we have been given that

           a = 1500

           r = 0.1

putting the required values in above equation we get

                   [tex]y = 1500 (1+0.1)^{t}\\y = 1500(1.1)^{t}[/tex]

Hence the exponential growth model for the future population is given as :

                      [tex]y = 1500(1.1)^{t}[/tex]

For the population in 7 years is :

                      [tex]y = 1500(1.1)^{7}\\y = 1500*1.949\\y = 2923.06[/tex]

The probability of getting-

Probability is the measure of how likely an event is to occur. Many events are impossible to predict to absolute certainty. We can only predict the possibility of an event occurring, i.e. how likely it is to occur, using it.

The formula for probability is;

Probability(event) = favourable outcome/ total outcome

Now, as per the given question;

There are 27 papers put in a hat numbering from 1 to 27.

The sample space will  be;

s = {1,,2,3,4,5,6,7,8,9,10,11,12,13,14,15,16,17,18,19,20,21,22,23,24,25,26,27}

The total outcome is 27.

The total number of 12 digit in the sample space is 1.

Thus, the probability for getting slip 12 is;

Probability(slip 12) = 1/27

The sample space for even number are;

s = {2,4,6,8,10,12,14,16,18,20,22,24,26}

Now, there are total number of even digits in the sample space is 13.

Thus, the probability for getting even number is;

Probability(even) = 13/27.

The sample space for prime number are;

s = {2,3,5,7,11,13,17,19,23}

Noe, the total number of prime digits in the sample space is 9.

Thus, the probability for getting prime number is;

Probability(prime) = 9/27 = 1/3

Therefore, the probability for getting the prime number is 1/3.

From the given information:

A bag 2 contains 2 red marbles, 2 green marbles, and 4 blue marbles.If we choose a marble, then another marble without putting the first one back in the bag.

Then

A bag contains 2+2+4=8 marbles in total.

We have to search out the probability of the subsequent events:

1. we've to settle on a red marble from the bag that contains 8 marbles in total, 2 of them are red

2. we've to decide on a green marble from the bag that contains 7 marbles in total, 2 of them are green.

The probability of the primary event to happens is:

P(one) = 2/8 = 1/4.

The probability of the second event to happen is:
