Okay. So, Marianna has 16 yards of fabric. Subtract 2 2/3 from 16, because those are the leftovers. 16 - 2 2/3 is 13 1/3. 13 1/3 / 3 1/3 is 4. Mariana made 4 pieces of 3 1/3 yard fabric. The answer is C: 4.
Answer:
x = 8, y = 
Step-by-step explanation:

Both 8 and x sides are congruent so they're equal.
Add 64 + 64.
Square root 128

Final answers: x = 8, y =

Answer:
Step-by-step explanation:
Using the problem statement as the basis for the equation, we can write ...
h -102 = 331
__
Using the diagram as the basis for the equation, we could write it as ...
h = 331 +102
__
The original height of the helicopter was 433 m.
Answer:
f(n) = 2 + 5n. This is an arithmetic sequence.
Step-by-step explanation:
f(1) = 7
f(2) = 7 + 5
f(3) = 7 + 5 + 5 = 7 +10
f(4) = 7 + 5 + 5 + 5 = 7 + 15
In general,
f(n) = 7 + 5(n -1 )
= 7 + 5n - 5
= 2 + 5n
We have the sequence 7, 12, 17, 22, 27 …
This is an arithmetic sequence, because it is a sequence of numbers in which the <em>common difference</em> between consecutive terms is 5.
