The answer would be E= 27 miles
You would start out by figuring out how many hours it would take him to swim by dividing 6/2 to get 3 then you would find out how long it would take him to run by dividing 15/6 to get 2.5 and you would add that to the 3 to get 5.5 and subtract that by 7 to get 1.5 which is how long he will have to complete leg 3 so you would take 18x1.5 to get 27 mph
Answer:
Answer is C
Step-by-step explanation:
When we do the vertical line test the line intersects (cause its a circle)
This could explain better
That's a quadratic equation in
![x^2](https://tex.z-dn.net/?f=x%5E2)
, which means we get an extra square root and
![\pm](https://tex.z-dn.net/?f=%5Cpm)
at the end.
![x^4 - x^2 - 42 = 0](https://tex.z-dn.net/?f=x%5E4%20-%20x%5E2%20-%2042%20%3D%200)
We factor,
![(x^2 - 7)(x^2+6) = 0](https://tex.z-dn.net/?f=%28x%5E2%20-%207%29%28x%5E2%2B6%29%20%3D%200)
![x^2 = 7 \quad \textrm{or} \quad x^2 = -6](https://tex.z-dn.net/?f=x%5E2%20%3D%207%20%5Cquad%20%5Ctextrm%7Bor%7D%20%5Cquad%20x%5E2%20%3D%20-6)

Answer:
34.5 square meters
Step-by-step explanation:
We assume you want to find the area of the shaded region. (The actual question is not visible here.)
The area of the triangle (including the rectangle) is given by the formula ...
A = 1/2bh
The figure shows the base of the triangle is 11 m, and the height is 1+5+3 = 9 m. So, the triangle area is ...
A = (1/2)(11 m)(9 m) = 49.5 m^2
The rectangle area is the product of its length and width:
A = LW
The figure shows the rectangle is 5 m high and 3 m wide, so its area is ...
A = (5 m)(3 m) = 15 m^2
The shaded area is the difference between the triangle area and the rectangle area:
shaded area = 49.5 m^2 - 15 m^2 = 34.5 m^2
The shaded region has an area of 34.5 square meters.
Answer: 8.175
Explanation: 8 is the whole number so set that aside look at 7/40, using simple division solve for a decimal
