Answer:
The rate of Yvone's hair growth is 3.1 cm per month.
Step-by-step explanation:
WIth the data from Yvonne's hair we can create a sequence that goes as follows:
A = {47, 50.1, 53.2, 56.3, 59.4,...}
This is an arithmetic sequence, the numbers are related to each other by a common difference, in other words to find the next number we just need to add a constant "r". To find this constant we can subtract any adjacent numbers on this sequence, this is shown below:
r = 50.1 - 47 = 3.1
r = 53.2 - 50.1 = 3.1
r = 56.3 - 53.2 = 3.1
and so on.
The rate of Yvone's hair growth is 3.1 cm per month.
Answer:
24.5
Step-by-step explanation:
the radius is half of a diameter
so the radius is 3.9
24.5 = 2πr= 2 * π * 3.9 ≈ 24.504

Answer:
- 340 quarters
- 1020 dimes
- 1031 nickels
- 2062 pennies
Step-by-step explanation:
x is the number of quarters
__
a) d = 3x . . . . . . the number of dimes is 3 times the number of quarters
b) n = d + 11 = 3x +11 . . . . there are 11 more nickels than dimes
c) p = 2n = 2(3x +11) = 6x +22 . . . . there are twice as many pennies as nickels
d) The total number of coins is ...
x + d + n + p = 4453
x + (3x) +(3x +11) +(6x +22) = 4453
13x +33 = 4453
13x = 4420
x = 4420/13 = 340 . . . . number of quarters collected
3x = 1020 . . . . . . . . . . . .number of dimes collected
1020 +11 = 1031 . . . . . . . number of nickels collected
2·1031 = 2062 . . . . . . . . number of pennies collected
There were 340 quarters, 1020 dimes, 1031 nickels, and 2062 pennies collected.
