(4/9)/x = 12
(4/9) = 12x
Divide both sides by 12
(1/27) =x
Explanation:
To find x we need to find the unknown side that connects the two triangles using the Pythagorean theorem:
a² + b² = c² (c is always hypotenuse)
So:
a² + 6² = 9²
a² = 9² - 6²
a² = 81 - 36
a² = 45
a = sqrt45
Now we do the same thing for the other triangle:
x² + 5² = sqrt45²
x² + 25 = 45
x² = 20
x = 2√5 or 4.5...
Answer: Percent of people who had a mild allergic is 0.6%.
Step-by-step explanation:
Since we have given that
Total number of people try a new shampoo = 7000
Number of people had a mild allergic reaction = 42
We need to find the "Percentage of people had a mild allergic":
Percentage of people had a mild allergic is given by

Hence, Percent of people who had a mild allergic is 0.6%.
Answer:
-7, -1, -7
-6, 0, 0
Step-by-step explanation:
x
x+6
7(x+6)
7(x+6)+ x(x+6) = 0
(x+6)(7+x) = 0
x = -6, -7
-6, 0, 0
-7, -1, -7
