Answer:

Part A: 84, 105

Part B: $315

Step-by-step explanation:

Part A:

4 student tickets + 5 adult ticekts = 9 tickets

The ratio of student tickets to adult tickets to total tickets is

4 : 5 : 9

He sold x times more tickets than the numbers on the ratio.

He sold 9x tickets.

9x = 189

x = 21

Student tickets:

4x = 4(21) = 84

He sold 84 student tickets.

Adult tickets:

5x = 5(21) = 105

He sold 105 adult tickets.

Part B:

Student tickets:

He sold 84 student tickets at $5 each.

The amount of money from the sale of student tickets is:

84 * $5 = $420

Adult tickets:

He sold 105 adult tickets at $7 each.

The amount of money from the sale of adult tickets is:

105 * $7 = $735

Difference:

$735 - $420 = $315

84 student tickets, 105 adult tickets were sold by Jin and $315  more money does Jin receive from selling adult tickets than from selling student tickets

Two or more expressions with an Equal sign is called as Equation

The ratio of student tickets to adult tickets sold is 4 : 5

4 student tickets + 5 adult ticekts = 189

4x+5x=189

9x = 189

Divide both sides by 9

x = 21

The number of Student tickets:

4x = 4(21) = 84

Jin sold 84 student tickets.

Adult tickets:

5x = 5(21) = 105

Jin sold 105 adult tickets.

Part B:

He sold 84 student tickets at $5 each.

The amount of money from the sale of student tickets is:

84 * $5 = $420

Adult tickets:

He sold 105 adult tickets at $7 each.

The amount of money from the sale of adult tickets is:

105 * $7 = $735

Difference:

$735 - $420 = $315

Hence 84 student tickets, 105 adult tickets were sold by Jin and $315  more money does Jin receive from selling adult tickets than from selling student tickets

Answer:

undefined

Step-by-step explanation:

To find the slope through 2 points

m = ( y2-y1)/(x2-x1)

   = ( -4 - -3)/(3 - 3)

    = ( -4+3)/(3-3)

    = -1/0

Since it is a number divided by zero, the slope is undefined

Answer:

if you mean expansion, we have;

Answer:

The equation of the line that passes through the points

(-4,4) and (6,4)

is

y=+4

Step-by-step explanation:

First of all, remember what the equation of a line is:

y = mx+b

Where:

m is the slope, and

b is the y-intercept

First, let's find what m is, the slope of the line...

The slope of a line is a measure of how fast the line "goes up" or "goes down". A large slope means the line goes up or down really fast (a very steep line). Small slopes means the line isn't very steep. A slope of zero means the line has no steepness at all; it is perfectly horizontal.

For lines like these, the slope is always defined as "the change in y over the change in x" or, in equation form:

m= y2-y1/ x2-x1

So what we need now are the two points you gave that the line passes through. Let's call the first point you gave, (-4,4), point #1, so the x and y numbers given will be called x1 and y1. Or, x1=-4 and y1=4.

Also, let's call the second point you gave, (6,4), point #2, so the x and y numbers here will be called x2 and y2. Or, x2=6 and y2=4.

Now, just plug the numbers into the formula for m above, like this:

m=0

So, we have the first piece to finding the equation of this line, and we can fill it into y=mx+b like this:

y=0x+b

Now, what about b, the y-intercept?

To find b, think about what your (x,y) points mean:

(-4,4). When x of the line is -4, y of the line must be 4.

(6,4). When x of the line is 6, y of the line must be 4.

Because you said the line passes through each one of these two points, right?

Now, look at our line's equation so far: y=0x+b. b is what we want, the 0 is already set and x and y are just two "free variables" sitting there. We can plug anything we want in for x and y here, but we want the equation for the line that specfically passes through the two points (-4,4) and (6,4).

So, why not plug in for x and y from one of our (x,y) points that we know the line passes through? This will allow us to solve for b for the particular line that passes through the two points you gave!

You can use either (x,y) point you want..the answer will be the same:

(-4,4). y=mx+b or 4=0 × -4+b, or solving for b: b=4-(0)(-4). b=4.

(6,4). y=mx+b or 4=0 × 6+b, or solving for b: b=4-(0)(6). b=4.

See! In both cases we got the same value for b. And this completes our problem.

m came out to be zero, so there is no "mx" term.

Answer:

r = (3V/π)^1/3

Step-by-step explanation:

Given that :

Volume of a sphere = V = 4/3πr³

Dividing into 4

4/3 * 1/4 πr³ = 4/12πr³ = 1/3πr³

V = 1/3πr³

Cross multiply

3V = πr³

Divide both sides by π

3V/ π = πr³/ π

3V/ π = r³

Take the cube root of both sides

r = (3V/π)^1/3

GP = {8 , 16 , 32 , 64 , 128 , 256 , 512 , 1024 , 2048 , 4096...} Therefore , the 10th term of the sequence is 4096.

I hope it help you

The required 10th term of the geometric sequence 8, -16, 32 is -4,096.

Geometric progression is a sequence of series whose ratio with adjacent values remains the same.

To find the 10th term of the geometric sequence 8, -16, 32, we first need to determine the common ratio (r) between consecutive terms.

r = (second term) / (first term) = (-16) / 8 = -2

So the common ratio is -2.

The nth term of a geometric sequence is given by the formula:

[tex]a_n = a_1 * r^{(n-1)}[/tex]

where [tex]a_n[/tex] is the nth term, [tex]a_1[/tex] is the first term, r is the common ratio, and n is the term number.

To find the 10th term, we plug in a1 = 8, r = -2, and n = 10:

[tex]a_{10} = 8 * (-2)^{(10-1)}a10 = 8 * (-2)^9a_{10} = 8 * (-512)a_{10} = -4,096[/tex]

Therefore, the 10th term of the geometric sequence 8, -16, 32 is -4,096.

Answer:

These responses do show strong evidence that the 75% figure is accurate for current high school graduates going off to attend college

Step-by-step explanation:

1453/2000 = .7265 or 72.65%

If 1,453 students of a 2,000 student high school attend college after high school, than 72.65% of the students in the high school on average will attend college after they graduate. This percentage compared to the 1990's are a mere 2.35% behind the 75% mark. In this example that is the difference between 1,453 students and 1,500 students. Since these percentages are relatively similar, a conclusion could be made that the 75% mark is an accurate average representation of how many high school graduates will attend college in the future.
