Answer: Option D.
Step-by-step explanation:
You can calculate the surface area of this right prism by adding the area of its faces.
You can observe that the faces of the right prism are: Three different rectangles and two equal triangles.
The formula for calculate the area of a rectangle is:
Where "l" is the lenght and "w" is the width.
The formula for calculate the area of a triangle is:
Where "b" is the base and "h" is the height.
You can observe that the hypotenuse of the each triangle is the width of one of the larger rectangle, then , you can find its value with the Pythagorean Theorem:
Where "a" is the hypotenuse and "b" and "c" are the legs of the triangle.
Then, this is:
Therefore, you can add the areas of the faces to find the surface area of the right prism (Since the triangles are equal, you can multiply the area of one of them by 2). This is:

Answer:
118%
Step-by-step explanation:
Cora's kitten weighed in the last visit to the veterinarian's office= 550 grams
Right now, Cora's kitten weighs = 1200 grams
Increase in the kitten's weight= 1200 - 550 = 650 grams
Percent increase in weight= 650/550 * 100
= 118.18% = 118%
Hence, there is 118% increase in kitten's weight.
Answer:
I think the perimeter of the diagram is 5 and if you round it like
If it's 5 or greater, add 1 to the digit in the tenths place, and then remove all the digits to the right. (In the example above, the hundredths digit is a 4 , so you would get 51.0 .) To round a number to the nearest hundredth , look at the next place value to the right (the thousandths this time).
