Step-by-step explanation:
There are 3 feet in a yard, so 420 feet is 420/3 = 140 yards.
The total number of yards Edith needs is ...
65 yd + 580 yd = 645 yd
So, the total number of balls of yarn Edith needs is ...
(645 yd)/(140 yd/ball) ≈ 4.61 balls
Edith needs to buy 5 balls of yarn to make her projects.
Answer:
2^-4, 1/16, (1/2)^4
There is a rule with exponents, if you are dividing two exponents you subtract the first exponent from the other to simplify it, also meaning it's equivalent.
So in this case 5-9 = 2^-4
The others were found by evaluation.
Since it says *10^5, we must multiply the number by 100,000.
To multiply a number by 100,000, move the decimal place of the original number 5 place values to the right. Fill in any necessary zero's.
Final answer: 183,000
