Answer:
1/2
Step-by-step explanation:
Using rise over run, you get 1/2. Hope this helps :), if you need the slope-intercept equation (y=mx+b), it's y=1/2x+0
Answer:
Step-by-step explanation:
Face perimeter is
7.5 + 4(1.5) + 3(2.5) = 21 ft
Perimeter wall area
21(1.5) = 31.5 ft²
Face area (x2 for front and back)
2(7.5(1.5) + 2.5(1.5)) = 30 ft²
Total surface area
31.5 + 30 = 61.5 ft²
Answer:
cost of journey of 25 miles = £ 17.5
Step-by-step explanation:
Base on the equation the cost of the journey can be represented as
C = 0.5n + 5
where
C = cost in £
n = number miles covered
To calculate the cost of a journey that is 25 miles we have to insert the value of n as 25 in the equation. Therefore,
C = 0.5n + 5
n = 25
C = 0.5(25) + 5
C = 12.5 + 5
C = £ 17.5
cost of journey of 25 miles = £ 17.5
Answer:
Step-by-step explanation:
<u>Use the law of cosines:</u>
![cos A=(b^2+c^2-a^2)/(2bc)](https://tex.z-dn.net/?f=cos%20A%3D%28b%5E2%2Bc%5E2-a%5E2%29%2F%282bc%29)
![cos A=(25^2+31^2-22^2)/(2*25*31)=0.711](https://tex.z-dn.net/?f=cos%20A%3D%2825%5E2%2B31%5E2-22%5E2%29%2F%282%2A25%2A31%29%3D0.711)
- m∠A = arccos(0.711) ≈ 44.7°
