The first cell phone bill of Ms. Trowbridge after 40% discount is $51.

Given information:

The discount on first cell phone bill = 40%

The flat charges on bill = $25

The charge per minute = $0.20

Since $0.20 is charged per minutes, the amount charged for 300 minutes will be :

300 x 0.20 = $60

Her monthly cell phone plan charges a flat monthly fee of $25.00.

the total amount charged will be;

$60 + $25 = $85

There is a 40% discount , then we have 40% of $85

= $34

So, the amount of her first cell phone bill ,

= $85 - $34

= $51.00

Hence, the first cell phone bill of Ms. Trowbridge after 40% discount is $51.

f(x) = a - x

y = a - x

y + x = a - x + x

y + x = a

y + x - y = a - y

x = a - y

f-¹(x) = a - x

The inverse of a function is the opposite of the function.

See below for the proof of: [tex]\mathbf{f(x) = f^{-1}(x)}[/tex]

The function is given as:

[tex]\mathbf{f(x) = a - x}[/tex]

Rewrite as:

[tex]\mathbf{y = a - x}[/tex]

Swap x and y

[tex]\mathbf{x = a - y}[/tex]

Make y the subject

[tex]\mathbf{y = a - x}[/tex]

Rewrite as:

[tex]\mathbf{f^{-1}(x) = a - x}[/tex]

Hence:

[tex]\mathbf{f(x) = f^{-1}(x) = a - x}[/tex]

Answer = 100 Rs

Explanation:

Given, the profit is 30% and the amount of profit is 30 Rs.

So, we can say that 30% = 30Rs

1% = 30/30

100% = 30(100)/30

100% = 100

The Cost Price is 100 Rs

Answer: 22

Step-by-step explanation:

Answer:

the answer is 22

Step-by-step explanation:

you have the -22 ferinhiet and then you add 44 and you have positive 22and you get the 44 from the negative because you atuomatically add the oppisite of -22 and you get positive 22 and -22 + 44 = 22 :)

Answer:

Plot the point, and draw a right triangle from that point and the x-axis.

The hypotenuse is the speed.  Use  A^2 + B^2 = C^2 to calculate it.

Imagine a compass on your graph.  Straight up along the y-axis is North.  The angle clockwise from there to the hypotenuse is the compass direction of travel.  Use tan(3/4) to get the angle from the x-axis, then add 90 since it's in quadrant 4. (compass directions are never negative)

i hope that helpsss :)

Step-by-step explanation:

7x^4 y^8 z^5 + 14x^2 y^3 z^11

try to get the smallest of each number and variable outside if that makes any sense

14 can go into 7 two times so take out 7 and multiply it by the whole thing

7(x^4 y^8 z^5 + 2x^2 y^3 z^11)

then x y and z

Answer:

Area = 420.25 in²

Step-by-step explanation:

A rectangle is a quadrilateral (has four sides and four angles) with two pairs of opposite and parallel sides. All angles in a rectangle are 90 degrees each. Also, opposite sides are equal.

Let x represent the length of the rectangle and y represent the width of the rectangle. Hence:

Perimeter = 2(length + width)

82 = 2(x + y)

x + y = 41

x = 41 - y

The area of the rectangle (A) = length * width

A = xy

substitute x = 41 - y:

A = (41 - y)y

A = 41y - y²

The maximum area occurs at A' (dA / dy) = 0. Hence:

A' = 41 - 2y

0 = 41 - 2y

2y = 41

y = 20.5 inches

substitute y = 20.5 inches in x = 41 - y:

x = 41 - y = 41 - 20 .5

x = 20.5 inches

The area = xy = 20.5 in * 20.5 in

Area = 420.25 in²

Answer:

420.25 in²

Answer:

623.61 cm³

Step-by-step explanation:

Given:

Radius of sphere (r) = 5.3 cm

Required:

Closest volume of the ball

SOLUTION:

Volume of a sphere = ⁴/3πr³

Radius (r) = 5.3 cm

Plug in the value of r

Volume = ⁴/3*π*5.3³

Volume = ⁴/3*π*148.877

Volume = 623.61 cm³

623.61 cm³ is closest to the volume of the ball.

These are the factors of 45 (1, 45), (3, 15) and (5, 9).

Answer:  7 is not a factor of 45

Step-by-step explanation:

Explanation:

The formula for calculating the distance between two points is: d = √ ( x 2 − x 1 ) 2 + ( y 2 -y 1 ) 2  Substituting the points from the problem gives: d = √ ( 0 − 5 ) 2 + ( 4 − 1 ) 2   d = √ ( − 5 ) 2 + ( 3 ) 2 d = √ 25 9 d = √ 34 Or d =3 5.8 rounded to the nearest hundredth.

9x+11>4x - (17-9x)              simplify

9x+11> 13x -17                    move like terms, then combine

-4x>-28                              divide to isolate the variable

x<7

Step-by-step explanation:

12x-3x +11 > 4x - (17-9x)

9x+11 > 4x-17+9x

9x+11 > 13x-17

9x-13x > - 17 - 11

- 4x > - 28

x < 7
