A triangle is a basic geometric shape consisting of three straight sides and three angles, summing to 180 degrees. Triangles are classified based on side length into equilateral (all sides equal), isosceles (at least two sides equal), and scalene (all sides different), or by angle into acute (all angles less than 90 degrees), obtuse (one angle greater than 90 degrees), and right (one 90-degree angle). This versatile shape is fundamental in various fields, including mathematics, engineering, and architecture.

2. If you have eight apples and you get ten more apples, how many apples do you have in total?

15

16

18

20

To find the total number of apples, you simply add the number of apples you started with to the number of apples you received. Here’s the calculation:

Starting Amount: You initially have 8 apples.

Additional Apples: You receive an additional 10 apples.

By adding these two amounts together, you perform the arithmetic operation of addition:

8 apples+10 apples=18 apples

So, you end up with a total of 18 apples. This simple addition combines the initial quantity with the new quantity received to give the total count.

3. All the sides of a cube are equal in length.

True

False

All the sides of a cube are equal in length. A cube is a three-dimensional geometric figure with six equal square faces, meaning each side of each square is of the same length.

4. 189.35 + 247.68 = ?

437.03

580.33

440.23

The given question asks for the sum of 189.35 and 247.68. Adding these two numbers together yields a total of 437.03.

Explanation

The given question asks for the sum of 189.35 and 247.68. Adding these two numbers together yields a total of 437.03.

5. 50000mL = 50L

True

False

The statement is true because 50000 mL is equal to 50 L. This is because there are 1000 milliliters in a liter, so by dividing 50000 mL by 1000, we get 50 L.

Explanation

The statement is true because 50000 mL is equal to 50 L. This is because there are 1000 milliliters in a liter, so by dividing 50000 mL by 1000, we get 50 L.

6. 4x + 3 = 15 x = 18

True

False

The given equation is 4x + 3 = 15. To solve for x, we need to isolate the variable. Subtracting 3 from both sides gives us 4x = 12. Then, dividing both sides by 4 gives us x = 3. Therefore, the correct answer is False because x is equal to 3, not 18.

Explanation

The given equation is 4x + 3 = 15. To solve for x, we need to isolate the variable. Subtracting 3 from both sides gives us 4x = 12. Then, dividing both sides by 4 gives us x = 3. Therefore, the correct answer is False because x is equal to 3, not 18.

7. 1000 m = 10 kms

True

False

1000 meters (m) is equal to 1 kilometer (km), not 10 kilometers. The conversion factor between meters and kilometers is that 1 kilometer equals 1000 meters.

Explanation

1000 meters (m) is equal to 1 kilometer (km), not 10 kilometers. The conversion factor between meters and kilometers is that 1 kilometer equals 1000 meters.

8. How many sides does a cuboid have?

9. 8x = 2z 24x = 3y x + y + z = ?

44x

26x

13x

The equation 8x = 2z can be simplified to 4x = z. Similarly, the equation 24x = 3y can be simplified to 8x = y. By substituting these values into the equation x + y + z, we get x + 8x + 4x = 13x. Therefore, the answer is 13x.

Explanation

The equation 8x = 2z can be simplified to 4x = z. Similarly, the equation 24x = 3y can be simplified to 8x = y. By substituting these values into the equation x + y + z, we get x + 8x + 4x = 13x. Therefore, the answer is 13x.
