Which of the following rational numbers is equal to 3.4? (line above the four)

A: 31/9

B. 32/9

C. 33/9

D. 34/9

Answers

Answer 1
Hey there! :D

So, we can just divide all the numbers to figure it out. 

31/9= 3.44444444

32/9=3.5555556

33/9= 3.66666777

34/9= 3.777778

The closest number to 3.4 is 31/9. "A" is the correct answer. 

I hope this helps!

A stadium that seats 35,000 is slowly filling up with fans. The game starts at four o’clock. At noon the stadium owner estimates there are 4,000 fans who have already arrived early. At one o’clock he estimates just over 11,000 fans have found their seats and they appear to be coming in at a steady rate. He knows his stadium will be more than ninety percent full by game time. Choose the function below that best models this situation and tracks attendance from Noon to game time.

A. f(x)= .90x + 4,000
B. f(x)= 7,000x + 4,000
C. f(x)= 4,000x + 4,000
D. f(x)= 11,000x + 4,000

Answers

Answer:

B. f(x) = 7000x + 4000

Step-by-step explanation:

To find the best function for this situation, we need to list down all the things that we know first.

We currently have:

35000 total seats

4000 fans

11000 fans after an hour

So that means that after an hour, we had:

11000 fans - 4000 fans = 7000 fans

At one o'clock we had 7000 more fans arrive.

So we can assume that:

x = number of hours

f(x) = 7000x + 4000 will be the best function to use to find out if there that 90% of the stadium will be filled by game time.

To test this function let's use it:

f(1) = 7000(1) + 4000

f(1) = 11000

This is after hour 1.

Now let's see after hour 4 since the game starts at 4.

f(4) = 7000(4) + 4000

f(4) = 28000 + 4000

f(4) = 32000

So 90% of 35000 is:

35000 x 0.90 = 31500

By game time we have 32000 fans which is above 90% of the total number of seats.

So the stadium owners estimate is correct.

B.)There are no extraneous solutions to the equation.
C.)7
D.)10

Answers

d 10 right????????????:
ANSWER


D) 10

EXPLANATION

We want to solve the radical equation,

[tex] \sqrt{6n - 11} = n - 3[/tex]

Square both sides,



[tex]6n - 11 = (n - 3) ^{2} [/tex]

Expand brackets on right hand side,

[tex]6n - 11 = {n}^{2} - 6n + 9[/tex]

Rewrite in general quadratic equation form,

[tex] {n}^{2} - 12n + 20 = 0[/tex]

Factor to obtain,

[tex](n - 2)(n - 10) = 0[/tex]

Apply the zero product principle to get,

[tex]n = 2 \: or \: n = 10[/tex]


We put n=2 into the equation to get,

[tex] \sqrt{6(2) - 11} = 2 - 3[/tex]


[tex] 1 = - 1[/tex]


This statement is false, hence 2 is an extraneous solution


We put n=10, to get

[tex] \sqrt{6(10) - 11} = 10 - 3[/tex]


[tex] \sqrt{49} = 7[/tex]


[tex]7 = 7[/tex]


This is true, hence the only solution is
[tex]n = 10[/tex]

3. A family is building a circular fountain in the backyard. The yard is rectangular and measures 7x by 6x and the fountain is going to be circular with a radius of 2x. Once the fountain is build, what will be the area of the remaining yard?
A. 38x^2
B. [x] 2x^2 (21 – 2pi)
C. 42x^2 – 2pix^2
D. 38pix^2,

Answers

The yard is rectangular with a measurement of 7x by 6x. 
The fountain is circular with a radius of 2x.
Since we are looking for the remaining area, we need to know the area of the rectangular backyard and the circular fountain.

The formula for a rectangle is 
A=lw
where:
 l=length
 w=width 

So, 
A=(7x)(6x)
  =42x^2

Now for the area of the circular fountain, 
A=

Step [tex]1[/tex]

Find the area of the rectangular yard

the area of the rectangular yard is equal to

[tex]A=L*W[/tex]

where

L is the length side of the rectangle

W is width side of the rectangle

in this problem we have

[tex]L=7x\ units\\W=6x\ units[/tex]

[tex]A=L*W[/tex]

[tex]A=7x*6x[/tex]

[tex]A=42x^{2}\ units^{2}[/tex]

Step [tex]2[/tex]

Find the area of a circular fountain

we know that

the area of a circle is equal to

[tex]A=\pi r^{2}[/tex]

where

r is the radius of the circle

in this problem we have

[tex]r=2x\ units[/tex]

substitute

[tex]A=\pi (2x)^{2}[/tex]

[tex]A=4\pi x^{2}\ units^{2}[/tex]

Step [tex]3[/tex]

Find area of the remaining yard

Subtract the area of a circular fountain from the area of the rectangular yard

[tex]42x^{2}\ units^{2}-4 \pi x^{2}\ units^{2}=2x^{2}[21-2\pi][/tex]

therefore

the answer is the option B

[tex]2x^{2}[21-2\pi]\ units^{2}[/tex]

The concession stand at the local high school sells pretzels and lemonade. The total cost of two pretzels and a lemonade is $5.75. The total cost of two lemonades is $0.25 more than the cost of a pretzel. What is the cost of a pretzel? $1.25 $2.00 $2.25 $2.75

Answers

The pretzel would be $2.25

Cost of a pretzel is equals to $2.25.

What is system of equations?

" A system of equations is a finite set of equations for which we find the common solution."

According to the question,

'x' represents the cost of  pretzel

'y' represents the cost of lemonade

As per situation given system of equation are,

Situation1: The total cost of two pretzels and a lemonade is $5.75, which can be represented by equation:

[tex]2x + y = \$5.75[/tex]                              ____(1)

Situation2: The total cost of two lemonades is $0.25 more than the cost of a pretzel, which can be represented by equation:

[tex]2y = 0.25 +x[/tex]                                _____(2)

Multiply equation (1) by 2 we get,

[tex]4x + 2y = \$11.5[/tex]                              ______(3)

Substitute the value of 2y from (2) in (3) to get the cost of pretzel,

[tex]4x + 0.25 +x = \$11.5[/tex]

⇒ [tex]5x = 11.5 - 0.25[/tex]

⇒ [tex]5x = 11.25[/tex]

⇒ [tex]x =\frac{11.25}{5}[/tex]

⇒[tex]x=\$2.25[/tex]

Hence, cost of a pretzel is equals to $2.25.

1. To solve this exercise, you must use the "Intersecting chords theorem".

2. You have that:

AP=3.5 in
PC=6 in
DP=4 in

3. Then, by applying the "Intersecting chord theorem", you have:

(AP)(PC)=(BP)(DP)

4. When you substitute the values into (AP)(PC)=(BP)(DP), you obtain:

(3.5 in)(6 in)/BP(4 in)

4x-y = 15 3x+2y = -8 Multiplying the first equation by two makes for an easy elimination of the y variable. 8x - 2y = 30 3x + 2y = -8 Add vertically. 11x = 22.

William had $45 dollars to spend on vegetables. After buying 6 watermelons, he had $25.50 left. How much did each watermelon cost?

Answers

45-25.50 = 19.50 spent
19.5 / 6 = 3.25 per watermelon

Let us suppose cost of 1 watermelon be x.

Cost of 6 watermelons = 6x.

It is given after buying 6 watermelons, he had $25.50 left.Total amount William spends on vegetable is $45.

We can form an equation with above information's

6x+25.50=45

To solve for x we isolate the x term .25.50 is added to the x term .

Opposite of addition is subtraction .Subtracting 25.50 both sides we have:

6x=45-25.50

6x=19.50

Dividing both sides by 6

x=3.25.

Cost of each watermelon is $3.25.

We have been given that the assessed value of property in Enterprise County is $196,000,000. The county supervisors feel the county needs $9,525,000 in revenue.

To find the tax rate we need to find $9,525,000 is what percent of $196,000,000.
