Answer:
30.32 miles
Step-by-step explanation:
This is a four-part question.
First, you need to find the distance between all of the places.
Alanah to Mia:
Find the hypotenuse: 6^2+8^2= C^2
(After work: C=10)
Mia to Teresa:
14 miles (You can just count.)
Teresa to Arena:
Find the hypotenuse: 2^2+6^2= C^2
(After work: 6.32)
Then, you can add them all up!
10+14+6.32= 30.32 miles (your answer).
Answer:
30 8/25 or 24 + √40
Work:
Alanah to Mia:
We have a right triangle, so do a² + b² = c²
6² + 8² = c²
36 + 64 = 100
100 = 10²
c = 10
Mia to Teresa:
d = 14
Just count here, it's self-explanatory.
Teresa to Arena:
Right triangle again
2² + 6² = c²
4 + 36 = 40
√40 ≈ 6.32 = 6 8/25
Final Sum:
Add 10 14 and 6 8/25 to get your final answer.
10 + 14 = 24
24 + 6 8/25 = 30 8/25 mi
Know that the fraction is just an approximation, the actual answer in radical form would be 24 + √40

Name the multiplicative identity of -12i
Answer:
0
Step-by-step explanation:
The multiplicative identity of -12i is (1 + 0i) or 1.
What is an expression?An expression is a way of writing a statement with more than two variables or numbers with operations such as addition, subtraction, multiplication, and division.
Example: 2 + 3x + 4y = 7 is an expression.
We have,
-12i
This is a complex number.
The multiplicative identity is the value when multiplied by the given value gives the same value.
Now,
(1 + 0i) x -12i = -12i
Thus,
1 + 0i or 1 is the multiplicative identity.

“To graph y=2/3x+4, Emaan plots one point at (0,4) and a second point 2 units right and 3 units up at (2,7). He then draws a line through (0,4) and (2,7). What error did Emaan make?”
The “2/3x” area is meant to be a fraction.
Answer:
The error he made was adding 3 to the y value and adding 2 to the x value, instead of adding 2 to the y value and 3 to the x value.
Step-by-step explanation:
The slope can also be called "rise over run," or the change in y divided by the change in x.
In this situation, the slope is 2/3, meaning that a change in y of 2 units will increase the x value by 3 units.
Emaan switched these values when plotting the points, and did a change in 2 x values with a change in 3 y values.
From the point (0, 4), instead of plotting the point (2, 7), he should have plotted (3, 6).
The error he made was adding 3 to the y value and adding 2 to the x value, instead of adding 2 to the y value and 3 to the x value.

Emanuel can skateboard 3.375 miles against a 2-mph wind in the same amount of time he skateboards 6.375 miles with a 2-mph wind. Find the speed Emanuel skateboards with no wind.
Answer:
6.5 mph
Step-by-step explanation:
Given that :
Emanuel can skateboard 3.375 miles against a 2-mph wind in the same amount of time he skateboards 6.375 miles with a 2-mph wind. Find the speed Emanuel skateboards with no
Wind speed = 2mph
Let time taken to skateboard = t
Speed = distance / time
Distance of 3.375miles against 2 mph wind
Let skate speed = x
skate speed - wind speed=
(3.375 miles / t) + 2mph = x - - - (1)
Distance of 6.375miles with 2 mph wind
(6.375 miles / t) - 2 mph = x - - - - (2)
Equate (1) and (2)
(6.375/ t) - 2 = (3.375/ t) + 2
(6.375 - 3.375) / t = 2 + 2
3 / t = 4
3 = 4t
t = 3/4
t = 0.75
Hence, speed without wind will be :
(3.375 miles / 0.75) + 2mph = x
4.5mph + 2mph = 6.5 mph
