Answer:
1/100
Step-by-step explanation:
the problem description is not copied fully.
but I think I understand it.
since the ratio of the perimeter is 1/10, so is then also the ratio for each side.
that means the longest side of ABC is 4 units (40/10), right ?
anyway, when the ratio of lengths and distance is 1/10, then the ratio for the area is 1/10×1/10 = 1/100.
because for the area (baseline × height / 2) two lengths have to be multiplied. and that multiplies the scaling factor twice into the calculation effectively squaring it as the area scaling factor.
and 1/10×1/10 = (1/10)² = 1/100
Answer:
x=-9
Step-by-step explanation:
m=(y2-y1)/(x2-x1)
m=(-8-(-6))/(-9-(-9))
m=(-8+6)/(-9+9)
m=-2/0
undefined
x=-9
Answer:
The length of the bridge is 300 feet.
Step-by-step explanation:
Let A represent the length of one leg.
Let B represent the length of the other leg (i.e length of the bridge)
Let C represent the length of the Hypothenus.
From the question given above, the following data were obtained:
Length of Hypothenus (C) = 340 feet.
Length of one leg (A) = 160 feet.
Length of the bridge (B) =.?
The length of the bridge can be obtained by using the pythagoras theory as illustrated below:
C² = A² + B²
340² = 160² + B²
115600 = 25600 + B²
Collect like terms
115600 – 25600 = B²
90000 = B²
Take the square root of both side
B = √90000
B = 300 feet
Therefore, the length of the bridge is 300 feet
