Kristof bought a new terrarium, shaped like a rectangular prism, for his pet snake. The terrarium has a length of 1.8 × 102 cm,

zepelin [54]

Answer:

Volume of rectangular prism in scientific notation is $2.574\cdot10^{6}$ cubic centimeters and in standard form $2574000\text{cm}^{3}$ .

Step-by-step explanation:

Since we know that volume of a rectangular prism is length*breadth*height.

Sides of our rectangular prism are given in scientific notation as $\text{length}=1.8*10^{2},$ $\text{width}=1.3*10^{2}$ and $\text{height}=1.1*10^{2}$ .

Let us substitute our values in volume formula,

$\text{ Volume of rectangular prism}=1.8\cdot 10^{2}\cdot 1.3\cdot 10^{2}\cdot 1.1\cdot 10^{2}$

Upon using exponent product property we will get,

$\text{ Volume of rectangular prism}=1.8\cdot1.3\cdot 1.1\cdot 10^{(2+2+2)}$

$\text{ Volume of rectangular prism}=2.574\cdot10^{6}\text{cm}^{3}$

Now let us convert our volume in standard form as,

$\text{ Volume of rectangular prism}=2.574\cdot1000000\text{cm}^{3}$

$\text{ Volume of rectangular prism}=2574000\text{cm}^{3}$

Therefore, volume of rectangular prism in scientific notation is $2.574\cdot10^{6}$ cubic centimeters and in standard form $2574000\text{cm}^{3}$ .

i need help with the last two. I forgot the formula and wondering if you will help me find which one is and isnt a triangle

Nimfa-mama [501]

Answer:

3. D) 26, 7, 31

4. B) 6, 34, 27

Step-by-step explanation:

Both #3 and #4 use the same strategy: the two shorter sides' sum has to be greater than the longer side.

#3:

2 + 8 is 10, which is less than 13. So A wouldn't form a triangle.

12 + 22 is 34, which is the length of the longer side. So B wouldn't form a triangle either.

14 + 18 is 32, which is less than 40. So C wouldn't form a triangle.

7 + 26 is 33, which is greater than 31. So D would form a triangle.

D. 26, 7, and 31 are the only lengths of the ones shown that form a triangle.

#4:

17 + 18 is 35, which is greater than 19. So A would form a triangle.

11 + 22 is 33, which is greater than 25. So C would also form a triangle.

5 + 18 is 23, which is greater than 20. So D would form a triangle.

6 + 27 is 33, which is less than 34. So B wouldn't form a triangle.

B. 6, 34, and 27 are the only lengths of the ones shown that don't form a triangle.

Which best explains whether a triangle with side lengths 5cm , 13cm and 12 cm is a right triangle the triangle is a right

Brrunno [24]

Answer:

Right triangle.

Step-by-step explanation:

We are asked to determine whether the given side lengths are sides of a right triangle or not.

We know that side lengths of a right triangle are Pythagoras triplets. The square of the longest must be equal to sum of squares of other sides.

Let us check sides of our given triangle.

$13^2=5^2+12^2$

$169=25+144$

$169=169$

Since both sides of equation are equal, therefore, the given side lengths are sides of a right triangle.
