Answer:
18√2
Step-by-step explanation:
The smaller triangle sharing a vertex with the larger one is similar and half the area. That means its linear dimensions are √(1/2) = (√2)/2 times those of the larger triangle.
The line segment of interest has length ...
36 × (√2)/2 = 18√2
_____
The ratio of area of similar figures is the square of the ratio of their linear dimensions. Thus the ratio of linear dimensions is the square root of the ratio of area.
I believe it is 64 degrees
Answer:
81.11 in decimal
81 1/9 in fraction
Step-by-step explanation:
Let the number be x
1.9 time a number is equal to 1.9x
1.7 plus 1.9 times a number is equal to 1.7 + 1.9x
Now given that
1.7 plus 1.9 times a number equals the sum of the number and 74.7
mathematically we have relation equation as
1.7 + 1.9x = x + 74.7
subtracting 1.7 from both side
1.7 + 1.9x - 1.7 = x + 74.7 - 1.7
=> 1.9x = x + 73
subtracting x from both side
1.9x - x = x + 73 - x
0.9x = 73
dividing both side by 0.9
0.9x/0.9 = 73/0.9
x = 81.11 or 81 1/9
Thus, the number is
81.11 in decimal
81 1/9 in fraction
Answer:
f(3) = 3
Step-by-step explanation:
f(x) = (1/7)(7x)
f(3) = (1/7)(7×3)
f(3) = (1/7)(21)
f(3) = 3
