An exercise ball, also known as a yoga ball, is a ball constructed of soft elastic with a diameter of approximately 35 to 85 centimeters (14 to 34 inches) and filled with air. The air pressure is changed by removing a valve stem and either filling with air or letting the ball deflate. It is most often used in physical therapy, athletic training and exercise. It can also be used for weight training. The ball, while often referred to as a Swiss ball, is also known by a number of different names, including balance ball, birth ball, body ball, ball, fitness ball, gym ball, gymnastic ball, physio ball, pilates ball, naval mine, Pezzi ball, stability ball, Swedish ball, or therapy ball.
Answer:
Ezra will have 5 ounces of water leftover
Step-by-step explanation:
I first divided 4,005 by 16 to get 250.3125, which I rounded to 250. Then I multiplied 250 by 16 to get how many ounces Ezra used, which is 4,000. Then I subtracted that value from how many ounces she had to get how many she had leftover.
Answer: option c. She subtracted the coefficients instead of dividing them
Explanation:
1) Starting expression (given):
2) Simplified expression (given)
3) Note that if you do the operations correctly you get:
i) By dividing the coefficients:
ii) By subtracting the exponents
And that is the correct result.
4) But if you subtract the coefficients, instead of dividing them, then you get 10 - ( - 5) = 10 + 5 = 15
Which is what she obtained in the numerator. And this is wrong, because the coefficients must be divided.
It is the exponents what you subtract, as per the rule of quotient of powers.
If you do cross multiplication you would get
60x=1800
x=30 to be exact so the answer is choice d
