Answer:

4500 feet

Step-by-step explanation:

Unit Conversion used:

1 yard = 3 feet

Unit multipliers used:

$(30 laps)/(1 week)$

$(25 yards)/(1 lap)$

$(3 feet)/(1 yard)$

The unit multipliers are set up in such a way that when they are multiplied with eachother, the initial unit of “weeks” gets cancelled out and the final answer is assigned the units of “feet”

∴Total distance he swam during = $(2 weeks)$ × $((30 laps)/(1 week))$ × $((25 yards)/(1 lap))$ × $((3 feet)/(1 yard))$

hiswinter break = 4500 feet

$t_{(1)/(2)}=5730\n N_0=120\ g\n t=2t_{(1)/(2)}=2\cdot5730=11460\n N(t)=?\n\n N(t)=N_0\left((1)/(2)\right)^{\frac{t}{t_{(1)/(2)}}}\n N(11460)=120\cdot\left((1)/(2)\right)^{(11460)/(5730)}\n N(11460)=120\cdot\left((1)/(2)\right)^2\n N(11460)=120\cdot(1)/(4)\n N(11460)=30\ g$

After one half-life . . . 1/2 of the total parent material

After another half-life . . . 1/2 of the half remains = 1/4 of the total original parent

If the original parent is 120 grams, then (1/4 x 20) = 30 grams remains
after 2 half-lives. It makes no difference what the substance is, or
how long its half-life is.

What is arithmetic?

In mathematics, it deals with numbers of operations according to the statements. There are four major arithmetic operators, addition, subtraction, multiplication and division,

What is simplification?

The process in mathematics to operate and interpret the function to make the function or expression simple or more understandable is called simplifying and the process is called simplification.

Here,
Length of ribbon 1 = 6 1/4 feet
length of ribbon 2 = 11 1/2 feet
Total length = 6 1/4 + 11 1/2
= 6 + 11 + 1/4 + 1/2

= 17 + [1*2 + 1*1] /2
= 17 + 3 / 4
= 17 3 / 4

Thus, the required total length of the ribbons is 17 3 /4 feet.
