To answer we let x be the distance he covered in the first part of the trip and y be the distance in the second part of the trip. The time it took him to finish the first trip is x/8 and the second y/20. The equations that best represent the given scenario is,
x + y = 15
x/8 + y/20 = 1.125
The values of x and y are 5 and 10, respectively.
Answer:
x>7
Step-by-step explanation:
First, you take away 6 from both sides, which gives you 4x>-x+35. Then you add x to both sides, which makes it 5x>35. Divide both sides by 5, and you get x>7
Answer:
4.03 is your answer.
Step-by-step explanation:
4.836 divided by 1.2
4.836/1.2 = 4.03
4.03 is your answer.
Answer:
The volume of the regular tetrahedron is 283.5 m³
Step-by-step explanation:
The formula of the volume of the regular tetrahedron is V = 
A h, where
∵ The area of the base of a regular tetrahedron is 98.9 m²
∴ A = 98.9 m²
∵ The height of it is 8.6 m
∴ h = 8.6 m
→ Substitute them in the formula of the volume above
∵ V = (98.9)(8.6)
∴ V = 283.5133333 m³
→ Round it to the nearest tenth of a cubic meters
∴ V = 283.5 m³
∴ The volume of the regular tetrahedron is 283.5 m³
Answer:
Linear polynomial.
Step-by-step explanation:
A linear polynomial is written with a degree 1. An example of a linear polynomials includes 3x + 5. This is what 5b - 1 is.
