Answer: [tex]10(512 – c) + 5c = 3,570[/tex]

Step-by-step explanation:

Given : The number of student tickets sold is represented by c.

For a school drama performance, student tickets cost $5 each and adult tickets cost $10 each.

The sellers collected $3,570 from 512 tickets sold.

Since , the total tickets sold = 512

Therefore , the number of adults ticket = [tex]512-c[/tex]

Now, cost of total child tickets : [tex]5c[/tex]

Cost of total adult tickets = [tex]10(512 – c)[/tex]

Now, according to the cost of the tickets , we have the following equation :-

[tex]10(512 – c) + 5c = 3,570[/tex]

Choose a graph from the list of graph, like in the picture.

Answer:

y = 0x + 9

Step-by-step explanation:

the equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y-intercept )

here m = 0 and c = 9, hence

y = 0x + 9

The equation of a horizontal line is normally written as y = 9

with the x- term omitted

The equation of a line with a slope of 0 and a y-intercept of 9 is y = 9, which represents a horizontal line on the graph.

The student is asking about the equation of a line in slope-intercept form, which is y = mx + b, where m is the slope and b is the y-intercept. Given that the slope (m) is 0, and the y-intercept (b) is 9, the equation of the line is simply y = 0x + 9. Since any number multiplied by zero is zero, this simplifies to y = 9.

Therefore, the equation of the line with a slope of 0 and a y-intercept of 9 in slope-intercept form is y = 9. This represents a horizontal line that crosses the y-axis at 9.

Step-by-step explanation:

Subtract the 680 from 960, then divide the product by 52000 to get the answer

Answer: Zoe is closer to the actual product because 6.80 is closer to 6.8493 than 6.90 mathematically. Another way to estimate 6.8493 is to round to the nearest hundredth place: 6.85

Zoe will have an estimate closer to the actual product.

To determine who will have an estimate closer to the actual product, we can compare the rounding methods used by Zoe and Andrew. Zoe rounded 6 * 8493 to 6 * 8000, while Andrew rounded 6 * 8493 + 6 * 9000. In this case, Andrew's estimate will be closer to the actual product because he considered additional terms in his calculation.

Another way to estimate 6 * 8493 that would give a better estimate is to round each term separately before multiplying. For example, rounding 6 to 10 and 8493 to 8500, the estimate would be 10 * 8500 = 85,000.

Answer:

The balance after 15 year is  $831.25 .

Step-by-step explanation:

Formula

[tex]Amount = P (1 + r)^{t}[/tex]

Where P is the principle and r is the rate of interest in the decimal form and t is the time.

As given

Caiden earned $475 from mowing lawns last summer.

He deposited this money in an account that pays an interest rate of 3.8% compounded annually.

Here

P = $475

3.8% is written in the decimal form.

[tex]= \frac{3.8}{100}[/tex]

= 0.038

r = 0.038

t = 15 years

Put in the formula

[tex]Amount = 475 (1 + 0.038)^{15}[/tex]

[tex]Amount = 475 (1.038)^{15}[/tex]

[tex]Amount = 475\times 1.75(Approx)[/tex]

Amount = $831.25

Therefore the balance after 15 year is  $831.25 .

Caiden will have approximately $850.91 in his account after 15 years of interest compounded annually at a rate of 3.8%.

In this problem, we're dealing with compound interest, not simple interest. The formula to calculate compound interest is: A = P (1 + r/n)^(nt), where A is the amount of money accumulated after n years, including interest; P is the principal amount (the initial money); r is the annual interest rate (in decimal); n is the number of times that interest is compounded per year; and t is the time the money is invested for in years. In this case, P equals $475, r equals 3.8/100 or 0.038 (transforming percentage to decimal), n is 1 (because the interest is compounded annually), and t is 15 years. Substituting these values into the formula gives: A = $475 (1 + 0.038/1)^(1*15). Calculate the bracketed part first, resulting in a figure around 1.038 and raise it to the power of 15, so we get a value around 1.7914. Multiply this by the initial amount of $475 to get the final balance after 15 years which will be approximately $850.91. Hence, Caiden will have $850.91 in his account after 15 years.

Answer: p = -2w + 20

Step-by-step explanation:

If the student had 20 pencils but now has 18 pencils, he uses pencils at a rate of 2 per week.  So, m = -2  (negative because he is decreasing the amount of pencils).  The student started with 20 pencils so b = 20

Use the y = mx + b but replace "y" with "p" and replace "x" with "w" and input the m and b as stated above:

             p = -2w + 20

Answer:

Step-by-step explanation:

Applying BODMAS here;

We first solve what is in the brackets:

9x - 81 -3 = -8x - 16

We then put the like terms together:

9x + 8x = -16 + 81 + 3

We then do the addition:

17x = -16 + 84

We then do the subtraction:

17x = 68

Simplifying this gives:

x = [tex]\frac{68}{17}[/tex] = 4

C. It is not always possible to calculate theoretical probability in complex situations, but experimental probability can be calculated any time experiments can be run.

The advantage of experimental probability over theoretical probability is that option C. It is not always possible to calculate theoretical probability in complex situations, but experimental probability can be calculated any time experiments can be run.

Probability is simply the possibility of getting an event. Or in other words, we are predicting the chance of getting an event.

The value of probability will be always in the range from 0 to 1.

Experimental probability is the probability where the probability of something is found by real experiments.

This is not computed by assuming or calculation.

Theoretical probability is the probability where the probability of something is found theoretically.

The probability is found using formulas and calculation.

So, it is not always possible to calculate theoretical probability in complex situations.

But experimental probability can be found in any case using experiments.

Hence the correct option is C.

Answer:

l = 20.5 cm

h = 17.5 cm

w =  9.5 cm

Step-by-step explanation:

Conditions

l+w =30     Solving for w     30 - l = w

h = l-3

V = l*w*h

Substituting in

V = l * (30-l) * (l-3)

   = (30l-l^2) (l-3)

   = 30 l^2 - l^3 - 90l + 3l^2

Combining like terms

Step-by-step solution

-l^3 + 33 l^2 - 90 l

To find the maximum we need to take the first derivative and then set it equal to zero

-3l^2 + 66l -90 = 0

Factor out a -3

-3 (l^2 -22l +30) =0

Using my calculator and the quadratic formula

l = 11 - sqrt(91)

l = 11 + sqrt(91)

l = 1.5 or 20.5  approximately

If l = 1. then

h= l-3   would be negative  so

l = 20.5

h = l-3

h = 17.5 approximately

w = 30-l = 9.5 approximately

The slope-intercept form of the line passing through the point (7, -2) and parallel to the line y = -8x - 4 is y = -8x + 54. The required answer is y = -8x + 54.

To find the slope-intercept form of a line parallel to the given line, we need to determine the slope of the given line first.

The given line has a slope of -8 since it is in the form y = mx + b, where m represents the slope.

Since the line we are looking for is parallel to the given line, it will have the same slope of -8.

Now, we can use the point-slope form of a linear equation to find the equation of the line passing through the point (7, -2) with a slope of -8:

y - y1 = m(x - x1)

Substituting the values of the point and slope:

y - (-2) = -8(x - 7)

Simplifying:

y + 2 = -8x + 56

Rearranging the equation to the slope-intercept form:

y = -8x + 54

Therefore, the slope-intercept form of the line passing through the point (7, -2) and parallel to the line y = -8x - 4 is y = -8x + 54. The required answer is y = -8x + 54.

Answer:

Thus; Jupiter travels at 480 miles/m and in 6 minutes, it will travel 2880 miles.

Step-by-step explanation:

First to convert it you need to multiply 8 miles per second by 60 seconds because there are 60 seconds in a minute:

 8 miles    x    60 s 

1 second        1 min

The unit of seconds will cancel out so you will get 480 miles/ min

To get how far it travels in 6 min you need to multiply the speed by 6 minutes

480 miles   x  6 min = 2880

  1 min

The unit of minutes will cancel out to get 2880 miles
