Before you add the fractions, make sure they have a common denominator. The LCM of 6, 3, and 4 is 12.

6 \times 2 = 12 \\ 3 \times 4 = 12 \\ 4 \times 3 = 12

Change each fraction so that they have a common denominator.

\frac{1 \times 2}{6 \times 2} = \frac{2}{12}

\frac{2 \times 4}{3 \times 4} = \frac{8}{12}

\frac{1 \times 3}{4 \times 3} = \frac{3}{12}

Now add the 3 fractions:

\frac{2}{12} + \frac{8}{12}  + \frac{3}{12} = \frac{13}{12} \rightarrow 1 \frac{1}{12}

Your answer is 1 \frac{1}{12}

The wind speed near the center of a tornado is represented by the equation S=93logd+65, where d is the distance, in miles, that
dezoksy [38]

Answer:

Therefore,

Wind speed of a Tornado when it travels 4 miles is 121.0 miles per hour.

Step-by-step explanation:

Given:

The wind speed near the center of a tornado is represented by the equation,

S=93\log d+65

Where,

d =  the distance, in miles

S = the wind speed, in miles per hour.

To Find:

S = ? at d = 4 miles

Solution:

We have

S=93\log d+65        .........Given

Substitute d = 4 in above equation we get,

S=93\log 4 + 65=93\times 0.602 +65=120.99

Rounding the answer to the nearest tenth we have

S=121.0\ mph

Therefore,

Wind speed of a Tornado when it travels 4 miles is 121.0 miles per hour.

Kai had a gross weekly paycheck of $616 last week. Kai worked 6 hours for 4 of the days and 8 hours on 1 day. What is Kai's hour
gizmo_the_mogwai [7]

The correct answer is B. $ 19.25

Explanation:

To calculate the hourly rate of pay, first, let's calculate the total number of hours Kai worked, and then divide the total earned into the number of hours.

6 hours x 4 days = 24 hours

8 hours x 1 day = 8 hours

24 hours + 8 hours = 32 hours

This shows Kai worked a total of 32 hours. Now to find the hourly rate of pay, follow this procedure:

$616 (total earned) ÷ 32 hours = $19.25 each hour

This means Kai earns $19.25 for each hour of work and therefore the hourly rate of pay is $19.25.
