If the area is 1 sq meter, then that means that each of the smaller squares are 1/9 meters long and wide, since the square root of 1 is 1. To find the area of a right triangle, use the formula a*b/2. This makes 1/18 square meters for each triangle.

A.) 1/18 * 6 =  6/18 or 1/3 sq. meters

B.) The mini squares in this problem are made up of two right triangles, so the area of a mini square is twice that of a triangle. If we have nine mini squares, we have 18 triangles, which makes the 1 * 1 single square. What you should do is add half the area of a single square to the original:

18/2 = 9

So we add 9 to the eighteen right triangles, which means 27 triangles to make 1 1/2 square meters.

Hope this helped.

Wow. They worked hard to trip you up on this one!

First, don't let the word "decompose" spook you.

We are basically dividing 1 sq m into 9 equal pieces.

So each piece is 1/9 of a sq m.

Then, we make each small piece 1/2 of a square.

1/9 x 1/2 = 1/18.

Each triangle will be 1/18 of a sq meter.

So 6 will be 6/18 or 1/3 of a sq. meter

To figure 1.5 square meters out of triangles...

There are 2 triangles per small square, and 9 small squares per sq meter - and then you add 50% more.

(2 x 9) + (2 x 9 x .5) = 27 triangles

In planning a Thanksgiving vacation, you want to rent a car for a week and travel the Pacific Highway from San Francisco to San
Alex777 [14]

Answer:

The gas cost for the Camry will be $ 150.

Step-by-step explanation:

Since in planning a Thanksgiving vacation, you want to rent a car for a week and travel the Pacific Highway from San Francisco to San Diego, and you want to return to San Francisco via Las Vegas, Death Valley, and Yosemite National Park, and this trip covers approximately 1,500 miles, and you plan to return the car with a full tank of gasoline and are considering two options advertised by Hertz:

Toyota Camry, 40 mpg highway, costs $ 448.27 plus taxes and fees, totaling $ 533.65.

Toyota Prius Hybrid, 49 mpg highway, costs $ 610.58 plus taxes and fees, totaling $ 772.88.

In both cases, you must purchase gasoline, which costs $ 4.00 per gallon in California.

To determine the total cost of gasoline for the Camry, the following calculation must be performed:

(1,500 / 40) x 4 = X

37.5 x 4 = X

150 = X

Therefore, the gas cost for the Camry will be $ 150.
