Answer:

R(x) = (460 * 7x)*(20+ x)

Step-by-step explanation:

If exactly 20 people sign up :

Charge per person = $460

For passengers after 20:

At number of passengers = 20 ;

Cost = (fee * discount * number of additional passesengers) * (20 + Number of additional passengers

Let number of additional passengers after 20 = x

R(x) = ($460 * $7x) * (20 + x)

Hence,

R(x) = (460 * 7x)*(20+ x)

First you find out how much 1 bat ate

40 divided by 8 = 5

So each bat ate 5 insects

Multiply 5 by the 64 bats

64 * 5 = 320

Answer:

Y = 3

Step-by-step explanation:

2(4) = 8

Respuesta:

si lo que estás buscando es "el número", la respuesta es es "7"

Explicación paso a paso:

si nos dice que la tercera parte de una cifra es "4" debemos hacer lo siguiente:

4*3=12 (para sacar el resultado de la suma)

verificamos diviendo 12 entre su tercera parte: 12 entre 3=4

a 12 le restamos 5 para sacar el número que necesita la suma 12-5=7

entonces la tercera parte de la suma entre 7+5 ó bien 12, es 4

7+5=12       12 entre 3=4

Answer:

  72.6 cm

Step-by-step explanation:

It is the perimeter of the overall rectangle plus twice the depth of the notch.*

  P = 2(L+W) +2d

  P = 2(16 cm + 13 cm + 7.3 cm) = 2(36.3 cm)

  P = 72.6 cm

The perimeter of the shape is 72.6 cm.

_____

* You may be able to visualize this if you imagine the bottom (top) of the notch translated out (down) to the edge of the rectangle. That translation does not affect the length of the line segment, but helps convince you that only the two legs of the notch are added to the perimeter of the rectangle.

Answer:

35 in^2

Step-by-step explanation:

The area of a trapezoid is the average of the bases times the height.

Base 1: 8, Base 2: 6, Height: 5

(8 + 6)/2 = 7

7 * 5 = 35 in^2

Step-by-step explanation:

Let l be the length and w be the width of the frame.

We have 2(l + w) = 94 and l = 2w - 7.

Therefore 2[(2w - 7) + w] = 94.

=> 3w - 7 = 47

=> 3w = 54

=> w = 18

l = 2(18) - 7 = 36 - 7 = 29

Hence the length of the frame is 29in and the width of the frame is 18in.

Answer:

Step-by-step explanation:

100%-17.5%= 82.5%

82.5% (divide) 82.5%= 1%

so (1% of the orginal price)=

£264 (divide) 82.5%= £320= original price

The price of the computer is reduced by £56 which is 17.5% of £320.

A percentage is a value per hundredth. Percentages can be converted into decimals and fractions by dividing the percentage value by a hundred.

Given, The price of a computer is reduced by 17.5% and the reduced price is £264.

Let the original price be '£x'.

So, (100 - 17.5)% = 82.5% of '£x' is  £264.

∴ (82.5/100)×x = 264.

0.825x = 264.

x = 264/0.825.

x =  £320.

So, The price reduced is (320 - 264) =  £56.

It's not A since that means 1 3/4 or 7/4. That isn't a possible answer since 7/4 is greater than 1.

B: not the answer. You'll make 72000 almost 1000 times bigger if you use B.

C: same reason as B. Anything over 1 will make 72033 larger, not smaller

Step-by-step explanation:

The equation of the line in point-slope form;

y+39 = (-5/2)(x-14)

Rearrange to solve for y:

y+39 = (-5/2)x + 35

y = (-5/2)x + 4

Answer:

T-shirts: 200

Shorts: 50

Step-by-step explanation:

To solve, set up an equation using two variables to represent the number of t-shirts and shorts sold.  Let x = t-shirts sold. Let y = shorts sold.  2x + 4y = 600.    We know that x will be 4 times greater than y, so we can plug in some guesses that seem reasonable and use the equation to test our theories.  My first guess was 50 shorts, which by luck was the correct answer.  These problems can be tricky, but setting up an equation can prove to be a great help.

Answer:

Step-by-step explanation:

Answer:

Well, when we have a point in rectangular coordinates (x, y) and we want to write it in polar coordinates (r, θ) the rule we use is:

r = √(x^2 + y^2)

θ = Atg(Iy/xI) + 90°*(n - 1)

where n is number of the quadrant where our point is.

For example, if we are on the second quadrant, we use n = 2.

Now, if instead, we have the point (r, θ) and we want to rewrite it in rectangular coordinates, then the transformation is:

x = r*cos(θ)

y = r*sin(θ)

Now we have the point (- 2, -(5pi)/4) because the first part is negative, this number can not be in polar coordinates (r can not be negative) then we have:

x = -2

y = -(5*pi)/4

Using the first relation, we can find that:

r = √( (-2)^2 + (-5*3.14/4)^2) = 4.4

(rememer that the point (- 2, -(5pi)/4) is on the third quadrant, then we will use n = 3.)

θ = Atg(-(5*pi)/4/-2) + 90°*(3 - 1)= Atg((5*pi)/2) + 180° = 82.7° + 180° = 262.7°

Then the point that represents  (- 2, - (5pi)/4) in polar coordinates is the point:

(4.4, 262.7°)

If instead of degrees, the angle part is written in radians, we have:

180° = 3.14 radians.

262.7° = x radians.

then:

x/3.14 = (262.7)/180

x =  3.14*(262.7)/180 = 4.58 radians.

then the point will be:

(4.4, 4.58 radians)

Answer:

66 are chocolate. 120x1.45 66

The number of cupcakes sold that day was chocolate flavored will be 54.

The quantity of anything is stated as though it were a fraction of a hundred. A quarter of 100 can be used to express the ratio. Per 100 is what the term percent signifies. The symbol '%' is used to symbolize it.

A bakery sold a total of 120 cupcakes in a day, and 45% of them were chocolate flavored.

Then the number of cupcakes sold that day were chocolate flavored will be

Let x be the number of the cupcakes sold that day that was chocolate flavored.

x = 45% of 120

x = 0.45 × 120

x = 54

Thus, the number of cupcakes sold that day was chocolate flavored will be 54.

Answer: A) The only zero of the function is 3 which is where the graph of the function intersects the x-axis

Step-by-step explanation:

Remember, a quadratic function which has roots x = a, and x = b, can be written as:

p(x) = A*(x - a)*(x - b)

Where A is the leading coefficient. This is the factorized form of a quadratic.

We have the function:

f(x) = (x - 3)^2

Now, we could rewrite this as:

f(x) = (x - 3)*(x - 3) = 1*(x - 3)*(x - 3)

Then we wrote f(x) in its factorized form, from this, we can see that the roots of the function are x = 3, and x = 3 (we have the same root two times)

Then the only root of f(x) is x = 3.

Remember that a root (also called a zero) is the value of x where the function intersects the x-axis. then the correct option here is:

A) The only zero of the function is 3 which is where the graph of the function intersects the x-axis
