7000
Step-by-step explanation:
Answer:
13.4feet
Step-by-step explanation:
The set up forms a right triangle.
Given
Height of the staircase h = 12 feet
Base of the stairs b = 6feet
Required
Length of the ramp l
Using the pythagoras theorem
l² = h² + b²
l² = 12²+6²
l² = 144 + 36
l² = 180
l = √180
l = 13.42 feet
Hence the length of the ramp to the nearest tenth is 13.4feet
Step-by-step explanation:
y=2x+1
(-0.8; -0.6)
(x, y)
-0.6=2×(-0.8)+1
-0.6=-0.6
it's true
y=-3x-3
-0.6=-3×(-0.8)-3
-0.6=-5.4
it's not true
i hope you have understood how to do this exercise, so you can do B
2.56 times 0.03 is 0.0768 then round to hundredth is 0.08 i think
