Hello!

<em><u>REVIEW
</u></em>Perimeter is the distance around a shape. To calculate perimeter, you do: 2l + 2w

Area is calculated by multiplying the length and width together.

<em><u>Perimeter</u></em>

The length is 7. 2l = 2 × 7 = 14
The width is 4. 2w = 2 × 4 = 8

<em>Add together</em>

14 + 8 = 22

\framebox{The perimeter is 22 feet}

<em><u>Area

</u></em>The length is 7, and the width is 4.

7 × 4 = 28

\framebox {The area is 28 feet}

Formula for P:  P = 2W + 2L
Formula for A:  A = WL

Here, P = 2(4 ft) + 2(7 ft) = (8+14) ft = 22 ft
and    A = (4 ft)(7 ft) = 28 ft^2

notka56 [123]

Answer:

She could purchase from stores A, D and E.

Step-by-step explanation:

She needs 8 cups so I multiplied each price by 8;

Store A 0.49(8)=$3.92

Store B 0.51(8)=$4.08

Store C 0.55(8)=$4.40

Store D 0.48(8)=$3.84

Store E 0.45(8)=$3.60

A segment has an endpoint at (1,−2). The midpoint is at (−4,−2). What are the coordinates of the other endpoint?
vodka [1.7K]

Answer:

The other midpoint is located at coordinates (-9,-2) (Second option)

Step-by-step explanation:

<u>Midpoints</u>

If P(a,b) and Q(c,d) are points in \mathbb{R} ^2, the midpoint between them is the point exactly in the center of the line that joins P and Q. Its coordinates are given by

\displaystyle x_m=\frac{a+c}{2}

\displaystyle y_m=\frac{b+d}{2}

We are given one endpoint at P(1,-2) and the midpoint at M(-4,-2). The other endpoint must be at an equal distance from the midpoint as it is from P. We can see both given points have the same value of y=-2. This simplifies the calculations because we only need to deal with the x-coordinate.

The x-distance from P to M is 1-(-4)=5 units. This means the other endpoint must be 5 units to the left of M:

x (other endpoint)= - 4 - 5 = - 9

So the other midpoint is located at (-9,-2) (Second option)

ABCD is rectangle on a coordinate grid with side AB parallel to side CD. Side BC is perpendicular to AB. The slip of AB is 3/4.
dybincka [34]

The slope of BC is \frac{-4}{3}

Step-by-step explanation:

Let us revise some notes about slopes of lines

  • If two lines are parallel, then their slopes are equal
  • If to lines are perpendicular, then the product of their slopes is -1, that means if the slope of one is m, then the slope of the other is \frac{-1}{m}

∵ ABCD is a rectangle

∵ AB // CD

∴ The slope of AB = the slope of CD

∵ BC ⊥ AB

∴ The slope of BC × the slope of AB = -1

∵ The slope of AB = \frac{3}{4}

- To find the slope of BC reciprocal the slope of AB and reverse its sign

∴ The slope of BC = \frac{-4}{3}

The slope of BC is \frac{-4}{3}
