<span>1. </span><span>A penny weighs about 0.1 oz.
Now, we need to find the weights of pennies in pounds
=> always remember that in every 1 oz, there is 0.0625 pounds.
Since 0.1 is 1/10 of 1 oz, we need to find the value of it in pounds.
=> 0.0625 pounds / 10
=> 0.0625 pounds.
Therefore, in 0.1 oz of penny is
equivalent to 0.00625 pounds.
In problem like this, before determining the answer, you need to make sure that
both unit of measurements are the same. If not, then try to convert.</span>
Answer:
1,42 * 10 ^ -5
Step-by-step explanation:
La notación científica también se conoce como forma estándar.
Tenemos que realizar la siguiente operación y dejar el resultado en forma estándar.
Entonces;
0,00000826 * 235 × 10 ^ -7 / 0,0017 × 10 ^ -2
También;
8.26 * 10 ^ -6 * 2.35 * 10 ^ -5 / 1.7 * 10 ^ -5
= 19,411 * 10 ^ -11 / 1,7 * 10 ^ -5
= 1,42 * 10 ^ -5
