Answer:
x = 135
Step-by-step explanation:
m = length of perpendicular line to hypotenuse
81/m = m/144
m² = 81 x 144 = 11664
m =√11664 = 108
Using the Pythagorean theorem:
x² = 81² + 108² = 6561 + 11664 = 18225
x = √18225 = 135
Answer:
; indirect variation ; x = 2.4
<u>Step-by-step explanation:</u>
direct variation is when:
; where k is the constant rate
indirect variation is when: xy = k ; where k is the constant rate
In the table provide: x * y = 24 for each coordinate provided, so this is indirect variation, with equation: 
since k = 24, then input y = 10 and k = 24 into the equation above:



x = 2.4
Answer:
The correct answer is option A.
Step-by-step explanation:
Number of circles = 64
Number of square = 96
Number of triangles = 48
Factor of 64, 96 and 48;



Factors do these numbers have in common are:
64 = 2 × 2 × 2 × 2 × 2 × 2
96= 2 × 2 × 2 × 2 × 2 × 3
48= 2 × 2 × 2 × 2 × 3
Common factors = 2 × 2 × 2 × 2 =16
