Answer:
The answer is 8cm.
Step-by-step explanation:
The scale drawing uses a ratio of 2cm:1m. If the actual car is 4 meters long, you would multiply 2 by 4 to get 8cm. The actual new ratio on the map is 8cm:4m, which is equivalent to the one in the problem.
Answer:
3
Step-by-step explanation:
w= x
l= x-4
x(x-4) = 45
x^2-4x = 45
Answer:
i believe it might be 50%
Step-by-step explanation:
Answer:
x ≈ 42.3
Step-by-step explanation:
The law of cosines is given. For this problem, ...
a = 25, b = 30, c = x , C = 100°
Filling in these values, we have ...
x^2 = 25^2 +30^2 -2(25)(30)cos(100°)
x^2 ≈ 1785.4723
x ≈ √1785.4723 . . . . take the square root
x ≈ 42.3

Number of hours is x values and cost of service is y.
To find slope you have to find the change in y over the change in x.
We can use any points in the table to calculate this amount.
Eg, 3-5 hours and 125-175 dollars.
The difference in y values is $50 and the difference in hours is 2.
50/2=25
The slope is 25
