Answer:

43 students and 11 chaperones

Step-by-step explanation:

Let a = number of chaperones or adults

Let s = number of students

1) We could set up two equations and solve them simultaneously using the substitution or the elimination method.

s + a = 54

8a + 6.50s = 367.50

I choose the substitution method.

2) Solve for s or y. I choose s.

a = 54 - s

8(54 - s) + 6.50s = 367.50

--------------------------------------

432 - 8s + 6.50s = 367.50

432 - 1.50s = 367.50

-1.50s = 367.50 - 432

-1.50s = -64.50

s = [tex]\frac{-64.50}{-1.50}[/tex]

s = 43

3) Substitute the result into one of the two equations above. I choose the first one.

43 + a = 54

a = 54 - 43

a = 11

Answer:

Step-by-step explanation:

because 10 time 6 equals 60

Answer:

1001

Step-by-step explanation:

Using linear function concepts, it is found that:

a) The function is y = 88 - 6x.

b) The tank has been draining it for 9 minutes.

A linear function is modeled by:

y = mx + b

In which:

Item a:

Thus, the equation is given by:

y = 88 - 6x.

Item b:

This is x for which y = 34, hence:

y = 88 - 6x

34 = 88 - 6x

6x = 54

x = 9.

The tank has been draining it for 9 minutes.

The amount of water in the tank is given by y = -6x + 88, it would take 9 minutes for the water to remain 34 gallons.

An equation is an expression that shows the relationship between two or more variables and numbers.

Let y represent the amount of water after x minutes.

The Rock has an 88-gallon fish tank which can be drained at a rate of 6 gallons per minute. Hence:

m = -6, b = 88

y = -6x + 88

For 34 gallons:

34 = -6x + 88

x = 9

The amount of water in the tank is given by y = -6x + 88, it would take 9 minutes for the water to remain 34 gallons.

Answer:   [tex]\frac{5}{6}[/tex] of a yard

=========================================================

Explanation:

The longest is [tex]\frac{6}{6}[/tex] yard and the shortest is [tex]\frac{1}{6}[/tex] of a yard.

This is because 6 is the largest numerator and 1 is the smallest numerator.

Subtract the two fractions:

[tex]\frac{6}{6} - \frac{1}{6} = \frac{6-1}{6} = \frac{5}{6}[/tex]

We subtract the numerators while the denominator stays the same at 6 the entire time.

This is the difference between the longest and shortest ribbon, and the unit is in yards.

The equation of a circle with the given center and radius.

center = (-5,-1) and radius is 6

x²-y²-10x-2y-6=0.

What is the equation of circle?

The equation of the circle is the equation which is used to represent the circle in the algebraic equation form with the value of center point in the coordinate plane and measure of radius.

The standard form of the equation of the circle can be given as,

Here (h,k) is the center of the circle and (r) is the radius of the circle.

The equation of a circle with the given center and radius. center (-5,-1) and radius 6 has to be written. Use the above equation,

Thus, the equation of a circle with the given center and radius.

center (-5,-1) and radius is 6

x²-y²-10x-2y-6=0.

Answer: 162

Step-by-step explanation:

Explanation:

To start off, we'll need the volume of the fish tank.

Volume of a rectangular block = (length)*(width)*(height)

V = L*W*H

V = 48*30*30

V = 43,200

The volume of the tank is 43,200 cubic cm.

Divide this over the flow rate of 7200 cubic cm per minute to get

(43,200)/(7200) = 6

It will take Emily 6 minutes to completely fill the tank.

The difference between Roth IRA and a traditional IRA is that Contributions are taxed differently. That is option D.

An Individual Retirement Account (IRA) is an account that has tax advantages which is used for financial saving for a long term.

In Roth IRA, taxes are being paid while the individual is still working.

In traditional IR, taxes are being paid after retirement.

Therefore, the difference between Roth IRA and a traditional IRA is that Contributions are taxed differently.

2) according to the formula above:

Answer: [tex]x=n\pi , \frac{3\pi }{4} +n\pi[/tex]

Step-by-step explanation:

Since we have a product here, either term can be zero. We can individually set each term equal to zero:

[tex]tan(x)=0[/tex]

[tex]tan(x)+1=0[/tex]

Beginning with the first term. It is saying "tangent of what gives zero". Well, tangent of zero gives zero. The value pi also gives zero:

[tex]tan(0)=0[/tex]

[tex]tan(\pi )=0[/tex]

We can generalize this by saying 'x' is equal to pi multiplied by an integer 'n', where 'n' is 0, 1, 2, 3...

[tex]x=n\pi[/tex]

Moving on to the second term, lets subtract that 1 to the other side to get:

[tex]tan(x)=-1[/tex]

Tangent of what gives -1? That would be 3pi/4. Tangent is the ratio of sine and cosine. So, you can essentially think of tangent as the slope of the line on a unit circle. Refer to the figure below. Another location along the unit circle where we get -1 is at 7pi/4, which is just 3pi/4 shifted by 180 degrees. Therefore, we can generalize this solution by adding 'npi' to 3pi/4 to get:

[tex]x=3\pi /4+n\pi[/tex]

where 'n' is 0, 1, 2, 3...

Answer:

(x+6)^2+(y-5)^2 = 3.1622^2

Step-by-step explanation:

The equation for a circle can be represented by (x+_)^2+(y+_)^2 = r^2

So, we already can find this portion of the equation knowing the center of the circle:

(x+6)^2+(y-5)^2= r^2

Next, we find the distance between the two given points to find the radius.

6-5 = 1

-3--6 = 3

1^2+3^2 = c^2

1+9= c^2

10=c^2

3.1622...

So, now we know the full equation.

(x+6)^2+(y-5)^2 = 3.1622^2

Given:

A data set has a median of 12, an upper quartile of 15, a lower quartile of 10, a minimum of 4, and a maximum of 20.

To find:

The correct statement for the box plot.

Solution:

Lower quartile is 10 and upper quartile is 15, so the box will go from 10 to 15.

Median of the data set is 12, so a line dividing the box will be at 12.

Minimum value is 4 and lower quartile is 10, so the left whisker will go from 4 to 10.

Upper quartile is 15 and maximum value is 20, so the right whisker will go from 15 to 20.

Therefore, the correct option is B.
