The answer is 20%.
Step 1: Subtract the measured distance and the actual distance to calculate the error.Step 2: Divide the given value by the actual distance and convert it into the percentage.
the actual distance is 612 ftthe measured distance is 735 ft
Step 1: 735 ft - 612 ft = 123 ftStep 2: 123 ft / 612 ft = 0.20 = 20/100 = 20%
aka real answer 20.1%
Answer:
5 times 2 plus 3 plus 2 times 4
Step-by-step explanation:
Step-by-step answer:
Given:
A triangle
Perimeter = 60 cm
longest side = 4* shortest side (x)
Solution:
longest side = 4x
shortest side = x
third (intermediate side = 60 -x -4x = 60-5x
The triangle inequality specifies that the sum of the two shorter sides must be greater than the longest side to form a triangle. Hence
x + y > 4x
x + 60-5x > 4x
60 - 4x > 4x
8x < 60
x < 60/8 = 7.5, or
x < 7.5
Therefore to form a triangle, x (shortest side) must be less than 7.5 cm.
Examine the options: both 7 and 5 are both less than 7.5 cm.
40, 30 and 25 all have a problem because the longest side (4 times longer) will exceed the perimeter of 60.
Now also examine cases where 4x is NOT the longest side, in which case we need
4x>=y
or
4x >= 60-5x
9x >=60
x >= 6.67
so x=5 will not qualify, because 4x will no longer be the longest side.
The only valid option is x=7 cm
The side lengths for x=7 and x=5 are, respectively,
(7, 25, 28)
5, 20, 35 (in which case, the longest side is no longer 4x=20, so eliminated)
Answer:
ASA
Step-by-step explanation:
two angles are the same and one side is the same
