cupoosta [38]

Answer:

  54 mph

Step-by-step explanation:

Let s represent the slower speed. The product of speed and time is distance, which did not change between the two trips. So, we have ...

  1.8(s +6) = 2(s)

  10.8 = 0.2s . . . . eliminate parentheses, subtract 1.8s

  54 = s . . . . . . . . divide by 0.2

Fran's average speed on Sunday was 54 miles per hour.

____

Her trip was 108 miles long.

What is 280 million in scientific notation 
Phantasy [73]
The rule of scientifinc notation is that we can use number between 0 and 10, so here we can use 2.8. Lets do this
280 000 000 = 2.8 * 100 * 1 000 000
Now we can just multiply 2.8 by 10 to the power of number of 0 reapeted
So 2.8*10^8 - its the result

Olenka [21]

Answer: Third option.

Step-by-step explanation:

In order to solve the given exercise it is important to remember that:

1. Rational numbers are defined as those numbers that can be wrriten as a  simple fraction.

2. The symbol for Rational numbers is: Q

3. Integers can be positive numbers, negative numbers and zero.

4. The symbol for Integers is: Z

5. Fractions have the following form:

\frac{a}{b}

Where:

 "a" is the numerator and "b" is the denominator.

The numerator "a" and the denominator "b" are both Integers ( and b\neq 0)

Therefore, based on the information given above, you can conclude that Rational numbers are numbers of the form \{\frac{a}{b}|a,b ∈ Z,b\neq0\}

kherson [118]
To find how many hours Sonia work on her science project,we can multiply the working hours of Tony by the times Sonia did:

4 \frac{2}{3}  \times 1 \frac{1}{4}  \\  =  \frac{14}{3}  \times  \frac{5}{4}  \\  =  \frac{70}{12}  \\  = 5 \frac{10}{12}  \\  = 5 \frac{5}{6}
Therefore Sonia work on her science project for 5 5/6 hours.

Hope it helps!
