[tex]I = \frac{PRT}{100} = \frac{500 \times 11 \times \frac{1}{2} }{100} \\ \\ = 5 \times 11 \times \frac{1}{2} \\ \\ = 55 \times \frac{1}{2} \\ \\ I= \$ 27.5[/tex]

Answer:

One solution

Step-by-step explanation:

x+y=5

3x-y=-5

Add the equations together will get you:

4x=0

Divide the 0 by 4 to get the x alone will get you

x=0

Answer:

There's one solution

(0,5)

Step-by-step explanation:

There's one solution

We can tell this is true because of the 3x in the second on and just hte x in the first. If you look closely you'll see the coefficents for the x values is the only difference between the two.

Let's now solve

We need to get a positive variable by itself

let's take x+y=5 and solve for y

x-5= -y

y= -x+5

We can then plug this y value into the other equation

3x-(-x+5)= -5

3x+x-5= -5

4x= 0

x=0

Let's then plug this value in for x into any of the beginning equations

0+y=5

y=5

Answer:

0.90 seconds

Step-by-step explanation:

We will see that one complete revolution takes (2π/7) seconds.

Here we have the function:

f(x) = 33sin(7x−π/12) + 33

The time needed to do a full revolution is given by the period of the function.

Remember that:

sin(x) = sin(x + 2π).

Then:

sin(7x−π/12) = sin(7*(x + T) −π/12)

Then we must have:

2π = 7*T

Where T is the period.

Solving for T, we have:

2π/7 = T

This means that one complete revolution takes (2π/7) seconds.

Answer:

closest to 1

Step-by-step explanation:

The given fraction is converted into decimal to find the closest value as 1.

A fraction is a number written in the form a / b, where a and b are integers and b ≠ 0.

The number a is called as the numerator and b is the denominator.

The given fraction is 17/21.

It can be written in decimal as below,

⇒ 17/21 = 0.809

Now, the given decimal can be compared with 0, 1/2 and 1 as follows,

0.89 > 0, 1/2 and 0.89 < 1

Which implies that it is closest to 1.

Hence, the given fraction 17/21 is closest to the integer 1.

B. is the answer i did the test and it was right

Answer:

Let's denote students in D = in the drama club , S = in a sports team

P(D) = 85/330

P(S) = 200/330

P(D and S) = 60/300

P(D or S) = P(D) + P(S) - P(D and S)  = 85/330 + 200/330 - 60/330 = 15/22

P(neither D nor S) = 1- 15/22 = 7/22

Answer: X=4 Y=-6

Step-by-step explanation:

Well we know that y= -4x+10

So we can input that into the bottom equation

2x +2(-4x+10) = -4

2x +-8x+20=-4

-6x + 20= -4

-6x = -24

x = 4

We also have to find the value of Y

y=-4(4)+10

y= -16 + 10

y=-6

Answer:

Step-by-step explanation:

2x + 2y = -4

Substitute (-4x+10) for y:

2x + 2(-4x+10) = -4

2x -8x + 20 = -4

-6x = -24

x = 4

Step-by-step explanation:

In this scenario, the dependant variable would be the total cost of the rental for the bike. This is because the actual cost depends on the number of hours that the individual has decided to rent the bike. The independant variable is the number of hours that they chose to rent the bike since it does not depend on any other factor in the scenario.

Step-by-step explanation:

3 3/8

you multiply the denominator by the whole number and then add into numerator. so

8 x 3 = 24

           24+ 3 =27

Answer= 27/8

Answer:

First we have to found all the clothes that the manufacturer produces in 8 hours,

As given    120 clothes = produce in 1 hour

                  X clothes  = produce in 8 hour

By cross multiplication, we get

X= 120*8

X= 960  total clothes produced in 8 hours

As also given that in each hour 5 clothes damaged ,so we can write as

 5 clothes = damaged in 1 hour

Y clothes = Damaged in 8 hour

By cross multiplication we get

Y=  40 clothes damaged in 8 hour

So the total clothes that manufacturer produce with out damage clothe will be ,

Total normal clothes = X-Y   = 960 - 40  = 920 clothes

Slope = 4

Step-by-step explanation:

The slop of the line is going to be rise over run.

So take where it the y value is 20 as [tex]y_1[/tex], and where it hits about 32 as value [tex]y_2[/tex].

You have you x value when y1 as 5 and x value at yw as 8.

So what you will do here is

[tex]\frac{y_2 - y_1}{x_2-x_1}[/tex]

[tex]\frac{32-20}{8-5}[/tex]

[tex]\frac{12}{3} = 4[/tex]

So your slope is 4.

Answer:

x = -3

Step-by-step explanation:

To answer this question, you should first remember that the inside angles of a triangle will always add up to 180 degrees. Therefore, we can make an equation and solve it form there:

55 + 54 + (x + 74) = 180

We add like terms:

109 + (x + 74) = 180

Continue adding like terms:

183 + x = 180

Next, we dubtract to siolate the "x" variable:

x = -3

Hope this helps :)

x=-3

Step-by-step explanation:

To start off, you're going to want to know and understand that all the angles of triangle equal 180 degrees.

Now that we know a triangle equals 180 degrees, lets make an equation. This is equation can be 55+54+74+x=180.

Now, lets combine the like terms in the equation. The equation now becomes 183+x=180.

From here, we subtract 180 from both sides, which would get us x=-3.

To double check that this is correct and that it works, you can plug in the -3 where the x would be.

I hope this helped!! Let me know if you have any further questions.
