siniylev [52]3 years ago

Answer:

Use the formula for Arithmetic only if it is Arithmetic: a1+ (n-1)d

a represents the first number in the sequence, n represents the number, and d represent common difference

Use the formula for geometric sequence: an=a1r the exponent of r to n-1

an represents the nth term you are trying to find, a1 represents the first number, r represents the common ratio, and n-1 is just the nth term minus 1.

Once you figure out if the sequence is arithmetic or geometric you one of those formulas.

Marat540 [252]

Answer:

7/30 of her music library

Step-by-step explanation:

We are looking for 7/10 of 1/3. In this case this "of" means we will multiply the two fractions. To multiply fractions, we multiply

top × top

and

bottom × bottom

1/3 × 7/10

is 1×7 on top, and

3×10 on the bottom.

= (1×7)/(3×10)

= 7/30

7/30 cannot be simplified, so that is the answer.

What is the diameter of a circle with a circumference of 11.27 pi ft
KatRina [158]
Circumference of circle = 11.27π ft
so,
C = 2πr
or, 11.27π = 2πr
or, 11.27π/2π = r
so, r = 5.635 ft
now,
diameter = 2r
= 2 x 5.635
= 11.27 ft
