How do I write 3/5 as a percentage

2 answers:

Divide 3 by 5, and whatever decimal that you get, turn that into a percent. Ex: 1/2 as a percent is 1÷2=.5. That is 5 tenths, so it is 50%.

40% of an hour in minutes and secs

olga55 [171]

Answer:

40% of an hour equals: 24 minutes

40% of an hour also equals: 1440 seconds

Skills needed: Time Units Conversion

Step-by-step explanation:

1) First, we need to understand how to convert between hours, minutes, and seconds.

There are 60 minutes in 1 hour ==> 1 hour = 60 minutes

There are 60 seconds in 1 minute ==> 1 minute = 60 seconds

- This means that there are 3600 seconds in 1 hour ( $60*60=3600$ )

- This also means that there are 60 minutes in 1 hour

2) We are trying to find how many minutes (or seconds) 40% of an hour is.

---> When converted to decimal, $40\%=\frac{40}{100}=0.4$

40% of an hour = 0.4 hours

Since there are 60 minutes in an hour, there are $60*0.4$ minutes in 0.4 hours. $60*0.4=24$ so, 24 minutes in 0.4 hours.

Since there are 3600 seconds in an hour, there are $3600*0.4$ seconds in 0.4 hours. $3600*0.4=1440$ so, 1440 seconds in 0.4 hours.

Which of the algebraic expressions are not linear expressions? Select all that apply. a. 3x - 2 b. -9y c. -7x^2^ + 4x d. -1/2x^2

Sedaia [141]

Answer:

c, d and e

Step-by-step explanation:

A linear expression is an expression in which sum of exponents of variables is at most 1 in each of its terms.

Option a: $3x - 2$

Here, the exponent of the variable is 1.

So, it is a linear expression.

Option b: $-9y$

Here, the exponent of the variable is 1.

So, it is a linear expression.

Option c: $-7x^2 + 4x$

Here, the highest exponent of the variable is 2.

So, it is NOT a linear expression.

Option d: $-\frac{1}{2} x^2$

Here, the exponent of the variable is 2.

So, it is NOT a linear expression.

Option e: $8xy$

Here, sum of exponents of variables is 2.

So, it is NOT a linear expression.

Hence, c, d and e are NOT algebraic expressions.
