Answer:

49,050cents

Step-by-step explanation:

Given the expression for calculating the marginal cost per card of producing x note cards expressed as

C'(x) = -0.05x + 77

On intergrating the marginal cost, we will get the total cost

C(x) =  -0.05x²/2 + 77x

Substitute x = 900 into the resulting expression

C(900) =  -0.05(900)²/2 + 77(900)

C(900) = -20,250+69,300

C(900) = 49,050

Hence the total costs in cents is 49,050cents

Answer:

Girl's height: 3 1/3  ft

Giraffes height: 10 ft

Difference between the heights: 6  2/3

Step-by-step explanation:

Ok, so the question is  bit vague, so I'm not sure which of the following answers your are looking for, that's for you to put.

We have the girl's height.

We multiply the girl's height by 2 to get the giraffe's height.

We subtract the girls height from the giraffe's height to get the difference.

Answer:

Step-by-step explanation:

Since the Tootsie Roll lollipop is a sphere

volume of sphere= \(\frac{4}{3}piR^3\) = -0.25 \(in^3/min\)

the negative sign indicates that the volume is decreasing

upon differentiating

as the diameter given is =0.75 so radius will be = 0.375

\(dV/dt = 4piR^2*dR/dt\)

so \(dR/dt = 0.25/4*3.14 *(0.375)^2\)

So the radius is decreasing at the rate of dR/dt= 0.142in/min

The values of the functions are:

1. y = f(-7) = 128

2. y = f(5) = 0.0313

We can evaluate a function by substituting the given value into the equation of the function, then simplify.

Given the function, y = f(x) = (1/2) ^ x

1. Find the value of f(-7):

y = f(-7) = (1/2)^-7

y = f(-7) = 2^7

y = f(-7) = 128

2. 1. Find the value of f(5):

y = f(5) = (1/2)^5

y = f(5) = 0.0313

If Leila makes a dot plot of the heights of the girls in her class to the nearest ¹/₂ inch, the number of different heights that will include on the number line is 5.

A dot plot is a data visualization tool that consists of data points plotted as dots on a graph with an x- and y-axis.

The number of dots plotted on each number line shows the frequency of the data group.

Height    Frequency   Cumulative Frequency

56¹/₂             2                               2

Answer:

The sum of the interior angle measures of a regular hexagon is 720°.

Step-by-step explanation:

To find the sum of the interior angle measures of a regular hexagon, we can use the fact that any polygon can be divided into triangles. The formula to find the sum of the interior angles of any polygon with n sides is:

Sum of interior angles = (n - 2) × 180°

In the case of a hexagon, n = 6. So, we can plug this value into the formula:

Sum of interior angles = (6 - 2) × 180° = 4 × 180° = 720°

The sum of the interior angle measures of a regular hexagon is 720°.

To explain this using triangles, let's divide the hexagon into triangles. A hexagon can be divided into four triangles by drawing three diagonals from one vertex to the three non-adjacent vertices. Since the sum of the interior angles of each triangle is 180°, and we have four triangles:

Sum of interior angles of hexagon = 4 × 180° = 720°

The sum of the interior angle measures of a regular hexagon is 720°.

Answer:

63%

Step-by-step explanation:

To convert fractions to decimals:

Divide the top of the fraction by the bottom

he got \(\frac{126}{200}\) so

\(126\)÷\(200=0.63\)

To convert decimals to percentages:

multiply by 100 and add a "%" sign.

\(0.63\)×\(100\)=\(63\)%

The percentage of questions Tyee answered correctly is P = 63 %

A percentage is a number or ratio expressed as a fraction of 100. It is often denoted using the percent sign, %

The difference between an exact value and an approximation to it is the approximation error in a data value. Either an absolute error or a relative error might be used to describe this error.

Percentage change is the difference between the measured value and the true value , as a percentage of the true value

Percentage change =( (| Measured Value - True Value |) / True Value ) x 100

Given data ,

Let the percentage of questions Tyee answered correctly be P

Now , the total number of questions = 200

The number of questions Tyee answered correctly = 126

So , P = number of questions Tyee answered correctly / total number of questions

On simplifying , we get

P = 126 / 200

P = 0.63

Therefore , the value of P is 0.63

Hence , the percentage is 63 %

Answer:

We have a bonus of £3150

40% is divided between 3 managers, so if

100% = £3150

40% = X

Now we can solve this for X by taking the quotient of these two equations:

(100%/40%) = (£3150/X)

Then:

X = £3150*(40%/100%) = £1260

Then each one of the 3 managers gets:

£1260/3 = £420

Each manager gets £420

The other £3150 - £1260 = £1890

are divided between 12 salespeople, then each one gets:

£1890/13 = £157.5

Each one of the salespersons will get £157.5

Now there is the case where we divide the £3150 evenly between the 15 workers.

We get:

£3150/15 = £210

Each worker gets £210.

Notice that before, each salesperson gets £157.5 and in this case, each salesperson gets £210.

Then the statement:

"If the bonus is shared equally between all 15 people I will double the money."

Is false.

Answer:

The number of adults tickets sold equals 52.

Step-by-step explanation:

First, we need to establish the system of equations:

x= number of adults tickets sold

y= number of kids tickets sold

10x + 6y= 928

x + y=120

Now, we isolate x in one equation and change it in the other to obtain its value:

x= 120 - y

10(120 - y) + 6y = 928

1,200 - 10y + 6y = 928

272 = 4y

68 = y

x= 120 - 68= 52
