What is the area of the rectangle?
Molodets [167]

Answer:

D

Step-by-step explanation:

Please look at the attached picture for full solution.

Method 1 is using the shoelace method to find the area of the rectangle. Shoelace method can be used to find the areas of any polygons given their coordinates. The coordinates have to be taken in an anticlockwise order and ending with the first coordinate.

Method 2 is making use of the distance formula of two points. The formula is as shown below:

\sqrt{(x1 - x2) ^{2}  + (y1 - y2)^{2} }

Having found the distance of the length and breadth of the rectangle, you can now find its area since area of rectangle= length × breadth.

Washer and dryer cost $784 combined. The washer cost $66 less than the dryer. What is the cost of the dryer.
zvonat [6]

Answer:

$425

Step-by-step explanation:

Let the dryer cost x

and the dish washer cost y

x+y=784-----------1

y=x-66-------------2

put the value of y=x-66 in 1

x+x-66=784

2x= 784+66

2x=850

x=850/2

x=425

Hence the dryer cost $425

Park Crest Middle School has a population of about 400 Eighth Graders.
Kobotan [32]

Answer:

10^3 times

Step-by-step explanation:

Given

Let

P \to Park Crest Middle School

T \to Total

So, we have:

P = 400

T = 406240

Required

Determine the number of times T is greater than P

This is calculated by dividing T by P.

i.e.

n = \frac{T}{P}

So, we have:

n = \frac{406240}{400}

n = 1015.6

Approximate

n \approx 1000

As a power of 10, we have:

n = 10^3
