Answer:The circumference = π x the diameter of the circle (Pi multiplied by the diameter of the circle). Simply divide the circumference by π and you will have the length of the diameter. The diameter is just the radius times two, so divide the diameter by two and you will have the radius of the circle!Hope it helps!!!!

Simplify the expression (5÷5) ÷ 5 * (5^2 - 5)

Katyanochek1 [597]

[ Answer ]

$\boxed{\bold{4}}$

[ Explanation ]

Simplify / Solve: (5 ÷ 5) ÷ 5 · ( $5^{2}$ - 5)

--------------------------------

Rewrite

$\frac{\frac{5}{5} }{5}$ ( $5^{2}$ - 5)

Apply Rule ( $\frac{a}{a}$ = 1): $\frac{5}{5}$ = 1

$\frac{1}{5}$ ( $5^{2}$ - 5)

Multiply Fractions

$\frac{1 \ * \ 5^{2 \ - \ 5} }{5}$

Simplify

1 · ( $5^{2}$ - 5) = 20

Simplify

= $\frac{20}{5}$

Divide

20 ÷ 5

Answer

= 4

Answer:

x = 9

Step-by-step explanation:

Since the figures are similar then the ratios of corresponding sides are equal, that is

$\frac{x-1}{6}$ = $\frac{16}{12}$ ( cross- multiply )

12(x - 1) = 96 ( divide both sides by 12 )

x - 1 - 8 ( add 1 to both sides )

x = 9
