Answer:
1.It is B This is because if you put that expression in scientific notation that’s what you will get.
2.It is A This is because you need to take the translation and multiply them equally to get this scientific notation.
Step-by-step explanation:
hope this helped!
The area of each of the 4 triangles is
... A = (1/2)bh = (1/2)(4)(3) = 6
The area of the square base (in the center of the net diagram) is
... A = s² = 4² = 16
Then the total area is 4×6 + 16 = 40 square units.
The answer should be C,
To solve this question, we have to use the rule of triangle inequality. This means, lengths of the any 2 sides of a triangle added up, must be longer than the remaining side.
Therefore, we can try and see which one of the options fits the rule.
A.
35+25 > 10 ✔️
25 + 10 = 35❌
A cannot make a triangle.
B.
15 + 10 > 5 ✔️
10 + 5 = 15 ❌
B cannot make a triangle.
C.
35 + 45 > 55 ✔️
45 + 55 > 35 ✔️
35 + 55 > 45 ✔️
C can make a triangle.
D.
25 + 25 < 75 ❌
D cannot make a triangle.
Therefore, the answer should be C.
