Which statement is true?
Lelu [443]

Answer:

The statement that is true is:

A debt of $17 is a larger value than a debt of $20.

Step-by-step explanation:

Let us look at the statements one after the other to determine if they are true or not:

1) A debt of $17 is a larger value than a debt of $20: This is true because when measuring debts, we will consider the values in the negative sense (-). Therefore, a debt of $17 has a value of (-17) and a debt of $20 has a value of (-20). -17 is larger than - 20 on a number line, hence, a debt of $17 has a larger value for the debtor, than a debt of 20$

2) One half an apple is equivalent to 8 fourths apples:

one half an apple = \frac{1}{2}\ of\ an\ apple

8 fourths of an apple = \frac{8}{4} = \frac{2}{1}\ of\ and\ apple. Therefore, one half of an apple is not equivalent to 8 fourth of an apple.

3) 8.01 is a smaller increase in sales than 8.001: This statement is false because 8.001 is counted before 8.01, and the difference between 8.01 and 8.001 is:

8.01 - 8.001 = +0.009, hence, 8.01 is larger than 8.01 by a magnitude of 0.009

4) \frac{2}{3}\ below\ zero is a lower temperature than 6 below zero:

\frac{2}{3}\ below\ zero\ = (-\frac{2}{3})^\circ

6 below zero = - 6°

On the number line, -6 is smaller than -\frac{2}{3} hence the statement is false.

Kaia calculates the she spends 75 minutes of a school day in science class. If she spends 500 minutes in school, what percent of
GaryK [48]

Answer:

15%

Step-by-step explanation:

Since a percent is out of 100 we can make 75/500 to have the denominator of 100.

To do that you divide

500/5 = 100

and for the numerator

75/5 = 15

whatever you do to one side you must do to the other that's why I divided both sides by 5. The ending fraction would be 15/100 which is the same as 15%

Hope that helps and have a great day!
