Answers

Answer 1

Answer:

2. x=5

y=10

3. x=21

y=4

Step-by-step explanation:

2. 13y=20x+3y    10y=20x

8x+y=180-13y      14y=180-8x

y=2x    plugging that into 14y=180-8x   28x=180-8x     36x=180   x=5

plug x into 10y=20x    10y=100    y=10

3. 3(x+y)=(4x-9)    3x+3y=4x-9   x=3y+9

5x=180-4x+9        9x=189          x=21

plug 21 into x=3y+9     21=3y+9    12=3y    4=y

a carnival booth duck game offer cash prizes. the booth at 75 plastic ducks floating around in a wading pool. 4 ducks have a green stars on the underside, and you win $10 for selecting a duck with a green star. it costs $1 to select a duck. is this a fair game? ​

Answers

Answer:

No, it is not fair

Step-by-step explanation:

Here, we want to check if this is a fair game

To win a sum, a duck with a green star on the underside must be selected

The number of ducks with this is 4 out of 75

The probability of selecting one is 4/75

The expected value of selecting is ;

4/75 * 10 = 0.5333

The cost of selecting a duck is $1

The probability that a duck that wins will not be selected is 71/75 which at a price of $1 is 0.9467

Since the price to lose and the amount to win is not the same, then the game is not fair

Explain why 186,426 Is diviable by both 3 and 9

Answers

♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️

A number is divisible by 9 if the sum of its digits is divisible by 9.

Look :

[tex] \frac{1 + 8 + 6 + 4 + 2 + 6}{9} = \frac{27}{9} = 3 \\ [/tex]

Thus 186,426 is divisible by 9 .

_________________________________

Also a number is divisible by 3 if the sum of its digits is divisible by 3.

Look :

[tex] \frac{1 + 8 + 6 + 4 + 2 + 6}{3} = \frac{27}{3} = 9 \\ [/tex]

Thus 186,426 is divisible by 3 .

Two communication companies offer calling plans. With company x, it cost 35 cents to connect and then 5 cents for each minute.With company y, it cost 15 cents to connect and the 4 cents for each minute. Write and simplify an expression that represents how much more company x charges than company y, in cent, for n minutes

Answers

Answer:

34

Step-by-step explanation:

Subtract and divide

The amount of money company x charges than company y, in cent, for n minutes will be (20 + n) cents.

What is an expression?

Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.

Given that;

With company x, it cost 35 cents to connect and then 5 cents for each minute.

And, With company y, it cost 15 cents to connect and the 4 cents for each minute.

Now,

Since, With company x, it cost 35 cents to connect and then 5 cents for each minute.

Hence, The cost for n minutes with company x is,

⇒ 35 + 5n

And, With company y, it cost 15 cents to connect and the 4 cents for each minute.

Hence, The cost for n minutes with company y is,

⇒ 15 + 4n

Thus, The amount of money company x charges than company y, in cent, for n minutes = 35 + 5n - (15 + 4n)

                     = 35 + 5n - 15 - 4n

                     = (20 + n) cents

As part of your retirement, you wish to generate $2,000 monthly payments for a 15-year period. The annual interest rate is 5%. What minimum amount is necessary to fund these payments?

Answers

Answer:

$962.0

Step-by-step explanation:

The formula for amount is ;

[tex]A=P(1+\frac{r}n} )^{nt}[/tex]

where

A= amount at the end of the period= $2000

P=minimum amount necessary to fund the payments

r= annual interest rate = 5% = 0.05

n= number of compounding per year , 1

t= time period = 15 years

Applying the values to the formula as;

[tex]2000=P(1+\frac{0.05}{1} )^{1*15} \\\\\\2000=P(1.05)^{15} \\\\\\2000/2.079=P\\\\\\962.0=P[/tex]

graph y=3/4x-4 ....……………

Answers

You graph the y-intercept first... The y-intercept is -4 so you go down four units on the y-axis that will be your first point (0,-4). The slope is 3/4 and can be translated as rise over run. rise is numerator run is denominator. From the -4 You rise three units up since its positive three, and then you run 4 units to the right since the 4 is positive. Your second point should be at (4,-1).

The required graph is shown below that represents equation y = (3/4)x - 4.

The equation y = (3/4)x - 4 represents a linear function in slope-intercept form, where the coefficient of x is the slope of the line and the constant term (-4) is the y-intercept.

To graph the equation y = (3/4)x - 4, follow these steps:

Start by plotting the point (0, -4) on the y-axis. This is the point where the line intersects the y-axis.

Since the slope is 3/4, it means that for every 4 units moved to the right along the x-axis, the corresponding y-value moves up 3 units.

From the y-intercept (0, -4), move 4 units to the right and then 3 units up to find another point. This gives us the point (4, -1).

The two points (0, -4) and (4, -1), draw a straight line passing through both points. This line represents the graph of the equation y = (3/4)x - 4.

1 A high school talent show lasted a total of t minutes. There were 2 intermissions that were each the length of 8 the talent show. Which function can be used to find the number of minutes the talent show lasted, not including intermissions?​

Answers

Answer:

I think f(t)=1/4t

Step-by-step explanation:

Because of you multiply 1/8 times 2, it gives you 1/4. Not 100% sure tho

If total time is t and There were 2 intermissions each the length of 1/ 8  of the talent show then function to find the number of minutes the talent show lasted, not including intermissions  is f(t)= 3t/4 minutes .

What is a function ?

function is a relation from a  set  to another  set provided that each element of first set is related to a unique element of another set .

Here given that total time is t  minutes

And time of intermission is t/8 minutes

And there are total 2 intermissions

Hence function to find the number of minutes the talent show lasted, not including intermissions can be defined as

f(t)= total time - 2(time of intermission)

[tex]f(t) = t- 2\times \frac{t}{8}\\\\f(t)=t-\fract1}{4}\\\\f(t)=\frac{3t}{4}[/tex]

If total time is t and There were 2 intermissions each the length of 1/ 8  of the talent show then function to find the number of minutes the talent show lasted, not including intermissions  is f(t)= 3t/4 minutes .
