Answer:
a) 4 ; b) 8
Step-by-step explanation:
4×3-8 = 12-8 = 4
4×4-8 = 16-8 = 8
Answer:
8:125
Step-by-step explanation:
The ratio of the lengths would be the scale factor
The ratio of the volumes is the scale factor cubed
2^3 : 5^3
8:125
Answer:
I would say A
Step-by-step explanation:
Answer: 4/35
Step-by-step explanation:
Number of red marbles = 4
Number of blue marbles = 5
Number of green marbles = 6
Total number of marbles = 4+5+6 = 15
When a red marble is picked, the probability is 4/15, then to pick a green marble after that, we have 14 marbles left and probability of picking green is 6/14.
Now, probability of choosing a red marble from the bag, not putting it back, and then choosing a green marble will be:
= 4/15 × 6/14
= 24/210
= 4/35
What is the question? The angles add up to 180, so it is a triangle, however every triangles angles add up to that so there is no specific answer?
