Answer:
Step-by-step explanation:
<u>Given</u>
To find f(q+1),
<u>substitute x with q+1 in the given equation:</u>
- f(q + 1) = 6(q + 1) + 7 = 6q + 6 + 7 = 6q + 13
Answer: 49 cm² and 16 cm²
Step-by-step explanation:
1. If the triangles are similar and the ratio of the perimeter os 4:7, then the areas are in the following ratio:

2. You know that the sum of their areas is 65 cm², then, you can calculate the area of the larger triangle as following:

3. The area of the smaller triangle is:

<h3>Answer: independent </h3>
Reason:
Each cube doesn't affect the other one, which means that the probabilities are not altered. This is assuming that the cubes don't bump into each other when rolling on the table. So either there's enough space on the table, or they take turns one at a time.

Answer:
r = 2
Step-by-step explanation:
"A varies inversely with r cubed" means the relation is of the form ...
A = k/r³
We can find the value of k as ...
k = Ar³ = 72·5³ = 9000 . . . . . . . multiply the above relation by r³
And we can solve this for r to get ...
r³ = 9000/A . . . . . . divide by A
r = ∛(9000/A) . . . . . take the cube root
So, for A = 1125, we have ...
r = ∛(9000/1125) = ∛8
r = 2
