For What Values Of R Will The Area Of The Shaded Region Be Greater Than Or Equal To 12 Square Units?

Answers

Answer 1

Answer:

Draw a rectangle.. write 13 on the two longer sides of the rectangle then write 7 on the other two shorter ones. Then add them all up and there you go your answer!

Our equation would be 13 +  13 + 7 + 7 = 40 inches

Step-by-step explanation:

Answer 2

The values of r for which the shaded region will be greater than or equal to 12 square units is;

r ≥ 8

We can see a rectangle and a triangle in the given image.

With the triangle being the unshaded portion of the rectangle.

Thus;

Area of shaded portion = Area of rectangle - area of rectangle.

We know that formula for area of rectangle is;

A_r = length × width

Thus; A_r = 3 × r

A_r = 3r

Area of a triangle is;

A_t = ½ × base × height

A_t = ½ × r × 3

A_t = ½(3r)

Thus;

Area of shaded portion = 3r - ½(3r)

Area of unshaded portion = 1.5r

We are told that the area of the unshaded region should be greater than or equal to 12. Thus;

1.5r ≥ 12

r ≥ 12/1.5

r ≥ 8

Answers

Answer: I think it's 72 kilometers

Step-by-step explanation:

I am not really sure?????

The total distance that John’s float travels is 71.02 kilometers.

What is distance formula?

The distance formula which is used to find the distance between two points in a two-dimensional plane is also known as the Euclidean distance formula. On 2D plane the distance between two points (x1, y1) and (x2, y2) is Distance = √[(x2-x1)²+(y2-y1)²].

Given that, John’s float goes from point A to B, then to C, then to D, and back to A.

Here, DC =9 kilometers, AD=9 kilometers

A(-7, 5) and B(3, 2)

AB=√[(3+7)²+(3-5)²]

=√109

= 10.44 kilometers

B(3, 2) and C(2, -4)

So, BC =√[(2-3)²+(-4-3)²]

= √50

= 7.07

Now, distance =10.44+7.07+9+9

= 35.51 kilometers

If he repeats this route twice, the total distance that his float travels is

kilometers.

The total distance =2×35.51

= 71.02 kilometers

Therefore, the total distance that John’s float travels is 71.02 kilometers.

The slope is 1/2 and the Y intercept is -3, so the equation will be Y=1/2x-3

Answer:

y = ½x - 3

Step-by-step explanation:

The question is asking for the line to be formatted in the y = mx + b format.

m is the slope of the lineb is the y intercept

For this question, the slope is 1/2, for every 1 unit the line goes up (rise), it goes 2 units forward (run). The y intercept is -3, hence the equation of the line is y = ½x - 3.

-24x = -3 what is the solution to the equation?​

Answers

Answer:x = 1/8 = 0.125

Step-by-step explanation:Rearrange the equation by subtracting what is to the right of the equal sign from both sides of the equation :

                    -24*x-(-3)=0

Pull out like factors :

  -24x + 3  =   -3 • (8x - 1)

Solve :    -3   =  0

Solve  :    8x-1 = 0

Add  1  to both sides of the equation :

                     8x = 1

Divide both sides of the equation by 8:

                    x = 1/8 = 0.125

polygon QRST has vertices Q41/2 , 2 R 8/2 ,2 S 8 1/2 , -3 1/2 and T 4 1/2,-3 1/2 is polygon qrst a reactangle? justify your anwerer

Answers

Answer:

QRST is a rectangle.

Step-by-step explanation:

To decide whether this is a rectangle or not, we have the following options to choose from:

Prove that:

2 pairs of sides are parallel and one angle is 90°

2 pairs of opposite sides are equal and one angle is 90°

1 pair of sides is parallel and equal and one angle is 90°

All four angles are 90°

The diagonals are equal and bisect each other. (same midpoint)

I will go with option 1, because this only requires finding the slope of each of the 4 lines.

Note that:

points Q and R have the same

y

value

⇔

horizontal line

points S and T have the same

y

value

⇔

horizontal line

points Q and T have the same

x

value

⇔

vertical line

points R and S have the same

x

value

⇔

vertical line

Therefore QRST has to be a rectangle because horizontal and vertical lines meet at 90°.

The opposite sides are therefore parallel and equal and the angles are 90°
