1. The measures of the length and the width of the picture are equal, so the picture is square shaped.

2. The enlarged picture will still be a square, since when we enlarge, we enlarge all distances with the same factor.

3. Let the dimensions of the large picture be a (length) by a (width)

4. Area of picture = a^{2}=192  in^{2}

a= \sqrt{192} =   \sqrt{16*12}= \sqrt{16*4*3}=4*2* \sqrt{3}=8\sqrt{3} (feet)

Answer: the dimensions are 8\sqrt{3} (feet) by 8\sqrt{3} (feet)

Someone please help me I only have until January 18th to turn this in. Question: Mr Lopez picks up 2 pallets of dog food to deli
miv72 [106K]

Answer:

Mr. Lopez delivers 1.5 tons of dog food to the animal shelter.

Step-by-step explanation:

Mr Lopez picks up 2 pallets of dog food to deliver to the animal shelter. Each pallet contains 40 bags of dog food, and the dog food weighs 37 1/2 pounds pet bag.

The weight of 1 bag of dog food = 37\frac{1}{2}\text{ pounds }

The weight of 40 bags of dog food = 40 \times 37\frac{1}{2} =1500 \text{ pounds }

Each pallet weighs = 1500 pounds

2 pallets weighs = 1500×2=3000 pounds.

We know that 2000 pounds = 1 ton

\frac{3000}{2000} \text{ pounds}=1.5 \text{ tons}

Hence, Mr. Lopez delivers 1.5 tons of dog food to the animal shelter.
