Mathematics

6 0

Answer:

x= 6.5 cm

Step-by-step explanation:

When a tangent line touches the circle, it forms a right angle triangle at that point

Apply the Pythagorean relationship in this case

Given that the height is = 20.2 cm = b

The hypotenuse is = c= x+14.7 cm

General formulae is;

a² +b² =c²

x² + 20.2² =( x+ 14.7)²

x² + 408.04= x² +14.7x+14.7x+216.09

x² + 408.04= x² + 29.4 x +216.09.........................collect like terms

x²-x² + 408.04-216.09= 29.4x

191.95= 29.4x-------------------------------divide by 29.4 t0 get x

191.95/29.4 =x

x=6.5 cm

8 + 4f = 3f solve for f
navik [9.2K]

Answer:

f=-8

Step-by-step explanation:

8+4f=3f

8+4f-4f=3f-4f (Subtract 4f from both sides of the equation to isolate f)

8=-f (Simplify)

-f=8 (Symmetric Property of Equality)

\frac{-f}{-1} =\frac{8}{-1} (Divide both sides of the equation by -1 to get rid of f's coefficient; remember that -f=-1*f, so -f has a coefficient of -1)

f=-8 (Simplify)

Hope this helps!

HELP ME PLEASE!!!
zaharov [31]

The correct answer to this question would be answer choice B.

To convert the decimal 0.56 to a fraction, first set it to a fraction over 100 which would be 56/100.

Then, because the question asks for the fraction to be in simplest form, look for the greatest common factor of the numerator and denominator or 56 and 100.

To find it, list out all of their factors:

56: 1, 2, 4, 7, 8 , 14, 28, 56

100: 1, 2, 4, 5, 10,20,25,50,100

Notice that out of all the factors listed, the greatest common factor listed is 4. Because of this, divide both the numerator and denominator by 4 to simplify your fraction to your answer: 14/25
