Answer:

$137.45

Step-by-step explanation:

First, we need to find the area of the circular rug in square feet.

Then we will multiply that with 1.75 to get total cost.

First,

Area of Circle = \pi r^2

Where r is the radius (which is half of diameter)

Given, diameter = 10 feet

Radius = 10/2 = 5 feet

Now, the area (A) :

A=\pi r ^2\\A = \pi (5)^2\\A = 25\pi\\A= 78.54

So, total cost would be:

78.54 * 1.75/sq ft = $137.45

andre has 4 times as many model cars as Peter , and Peter has one-third as many model cars as jade . andre has 36 model cars . a
lorasvet [3.4K]
P = how many cars Peter has
j = how many cars Jade has
a = how many cars Andre has
p x 4 = how many cars Andre has (36 model cars)
>>>TO FIND HOW MANY MODEL CARS PETER HAS:
p x 4 = 36
36 / 4 = 9
your equation to find how many model cars Peter has is:
36 / 4 = 9
So, Peter has 9 model cars.
>>>TO FIND HOW MANY MODEL CARS JADE HAS:
36 / 4 = how many cars Peter has (9)
Now, you are given the info that Jade has THREE TIMES (3x) as many cars as Peter already.
So, your equation for this one is:
9 x 3 = 27
So Jade has 27 model cars.

---- Jade has 27 model cars.
---- Andre has 36 model cars.
---- Peter has 9 model cars.

equation for a. 36 / 4 = p
equation for b. 9 x 3 = j

Ostrovityanka [42]

let the 2 integers be x and x + 2.

so we have the equation:-

3(x + 2)  = x - 10

3x + 6 = x - 10

2x = -16

x = -8

the integers are -8 and -6  answer

What is the inverse of the function f(x) = 2x + 1?
timama [110]

Answer:

  (a)  h(x) = 1/2x -1/2

Step-by-step explanation:

The inverse of the function y = f(x) is found by solving x = f(y).

__

<h3>setup</h3>

  x = f(y)

  x = 2y +1 . . . . . . use the definition of f(x)

<h3>solution</h3>

  x -1 = 2y . . . . . subtract 1

  (x -1)/2 = y . . . . divide by 2

  y = 1/2x -1/2 . . . . eliminate parentheses

  h(x) = 1/2x -1/2 . . . write in functional form

The inverse of f(x) = 2x+1 is ...

  h(x) = 1/2x -1/2
