Answer:
A. 9
Step-by-step explanation:
The scale factor = 3, meaning that you have to multiply the og shapes side lengths by 3 in order to get the new shapes side length.
We know that 10 × 3 = 30, so now we have to find what the width of the og rectangle will be.
27 / 3 = 9, so ? = 9.
To check your answer, you can multiply 9 × 3 = 27. So 9 is the missing width.
? = 9
Answer:
A. 675 units²
Step-by-step explanation:
The formula for the surface area of a square pyramid is ...
A = s(s +2h)
where s is the side length of the base, and h is the slant height of a face.
__
<h3>use the formula</h3>
The given pyramid has s=15 and h=15, so the surface area is ...
A = (15)(15 +2×15) = 15(45) = 675 . . . square units
Answer:
3/91 ; 36/91
Step-by-step explanation:
1) favourable event/ total possibilities * favourable event/ new total possibilities
3/14 * 2/13 = 3/91
2) it is simplier calculate the probability of the opposite event (no balls are blue)
11/14 * 10/13 = 55/91
91 - 55 = 36
final answer 36/91
