you go to a grocery store and buy a $2.50 bag of sugar and a sandwich for $1.75. The sales tax for your state is 7%. What is the

Rashid [163]

Answer: My guess is $4.55

Step-by-step explanation:

2.50 + 1.75 = 4.25 (This is the total of everything you bought)

4.25 x 0.07= 0.2975 (0.2975 is 7% of 4.25 but because this is money I will round it to <em>0.30</em>)

(0.30 is the tax so now add it to the original amount)

$4.25 + $0.30 = $4.55

Please can you help me anything will help please

Bumek [7]

Answer: 1, 2, 4, or 5

Step-by-step explanation:

The relationship in #3 is a function because all the x values are distinct, that is, none are repeated. (Y values don't matter.)

A function will not repeat any x values so if your goal is for the relationship in #4 to NOT be a function, repeat one of the x values. Any one will work.

Examine the following graph, where the function P(x) is mapped to I(x) by a translation.

Murrr4er [49]

f(x) = p(x) + 4 shows the correct transformation.

<h3>Define transformations.</h3>

A point, line, or geometric figure can be transformed in one of four ways, each of which affects the shape and/or location of the object. Pre-Image refers to the object's initial shape, and Image, after transformation, refers to the object's ultimate shape and location. The most typical varieties are listed below: When a figure is translated, it is moved in any direction. Flipping a figure over a line is called reflection. Rotation is the process of turning a figure a specific amount around a point.

Given,

Function

f(x) = p(x) + 4

shows the correct transformation.

-377 = x - 1,000 i dont under stand it

Naddika [18.5K]

Answer:

$\boxed {x = 623}$

Step-by-step explanation:

Solve for the value of $x$ :

$-377 = x - 1,000$

-Switch sides:

$-377 = x - 1,000$

$x - 1,000 = -377$

-Add $1,000$ on both sides:

$x - 1,000 + 1,000 = -377 + 1,000$

$\boxed {x = 623}$

Therefore, the value of $x$ is $623$ .

A gate is made up of a rectangle and a semicircle, as shown. Find the area of the gate. Use 3.14 for .Round your answer to the n

allochka39001 [22]

Answer:

<em>797.0ft²</em>

Step-by-step explanation:

<u>Find a related diagram attached</u>

Area of the gate = Area of the semicircle + Area of the Rectangle

Area of the semicircle = πr²/2

r is the radius

From the diagram, radius r = 20/2 = 10ft

Area of the semicircle = 3.14(10)²/2

Area of the semicircle = 3.14(100)/2

Area of the semicircle = 314/2

Area of the semicircle = 157ft²

Area of the rectangle = Length * Width

Area of the rectangle = 20*32

Area of the rectangle = 640ft²

Area of the gate = 157 + 640

Area of the gate = 797ft²

<em>Hence the area of the gate is 797.0ft²</em>
