Answer:
Perimeter = 28.8 inch
Step-by-step explanation:
Step 1: Change given centimeters into inches according to the scale
2.5 / .5 = 5 <--- length in inches
4.7 / .5 = 9.4 <--- width in inches
^^^This is the same thing as multiplying 2.5 cm and 4.7 cm by two. You could also reword the scale to be 1 cm = 2 inch if it makes more sense for you
Step 2: Find the perimeter using the formula: P = 2L + 2W
2 (5) + 2(9.4)
10 + 18.8
Answer:
x<2
Step-by-step explanation:
x- 2 <0
x < 2
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
46
I believe this is correct, if not lmk!
