Let the time that you caught up with your friend be t, then
8.5 - 3.4t = 8 - 3t
3.4t - 3t = 8.5 - 8
0.4t = 0.5
t = 0.5/0.4 = 1.25
therefore, you will catch up with your friend after 1.25 hours.
b.) time it will take you to cross the finnish line = 8.5/3.4 = 2.5 hours
After 2.5 hours, distance covered by your friend = 3 x 2.5 = 7.5 miles
Therefore, when you cross the finish line, you are 8 - 7.5 = 0.5 miles ahead of your friend.
Answer:2.26666666667
Step-by-step explanation:
The answer shows the next correct step for solving the quadratic equation by taking the square root of both sides is g-4 = ±√2
<h3>Solving by completing the square method</h3>
Quadratic equations are equation that has a leading degree of 2. Given the quadratic equation as shown below:
g²-8g + 16 = 2
Subtract 16 from both sides
g²-8g + 16 -16 = 2 - 16
g²-8g = -14
Complete the square
g²-8g + (-8/2)² = -14 + (-8/2)²
g²-8g + (-4)² = -14 + (-4)²
(g-4)² = -14 + 16
(g-4)² = 2
Take the square root of both sides
√(g-4)² = ±√2
g-4 = ±√2
Hence the answer shows the next correct step for solving the quadratic equation by taking the square root of both sides is g-4 = ±√2

a. The experimental unit:
The experimental units would be the lawyers that participate in this experiment. The experimental units are the subjects upon which the experiment is performed.
b. The response variable:
The response variable would be income. This is the variable that measures the response or outcome of the study.
c. The factors:
The factors are the variables whose levels are manipulated by the researcher. In this case, these would be the Mach score, classification and gender.
d. The levels of each factor:
The levels would include the levels of the Mach score (high, moderate, low) and the levels of gender (male, female).
e. The treatments:
The treatments are all the possible combinations of one level of each factor. Therefore, these are: High and male, high and female, moderate and men, moderate and female, low and male, low and female.
Answer:
120
Step-by-step explanation:
Just add the 20 back to 40 and times by 2
40 + 20 = 60
60 * 2 = 120
