Answer:
The height of the bridge is 71.47 m.
Step-by-step explanation:
Since the eye of the surveyor is 1.45m creating the horizontal distance, we must add the 1.45 m to the 70.02 m to determine the total height of the bridge.
70.02 m + 1.45 m = 71.47 m
The height of the bridge is 71.47 m.
Answer:
The solutions are -2 and 3
Step-by-step explanation:
You can find the solutions to a quadratic by looking at where the line/arch intersects the x-axis. In this case, the quadratic intersected it at -2,0 and 3,0.
We have 240/40 = total students/ 100
Total students are in the middle school is: (240 x 100)/ 40 = 600 students
I think the answer is 1/23
Please tell me if I'm wrong.
Answer:
x = 200
Step-by-step explanation:
Given
x - 
y = 30 ← substitute y = 15 into the equation
x - × 15 = 30 , that is
x - 10 = 30 ( add 10 to both sides )
x = 40 ( multiply both sides by 5 to clear the fraction )
x = 200
