Mala has a collection of bangles. She has 20 gold bangles and 10 silver bangles. What is the percentage of bangles of each type?

Rainbow [258]

Answer:

Percentage of gold bangles is 66.6 and of silver bangles it is 33.3

Step-by-step explanation:

Given:

Number of gold bangles Mala has = $20$

Number of silver bangles she has = $10$

Total number of bangles = $20+10$ = $30$

We have to find the percentage of each type of bangles.

So,

Percentage of bangles = $\frac{No.\ of \ bangles\ each\ type}{Total\ no.\ of \ bangles} \times 100$

Percentage of gold bangles.

⇒ $\frac{20}{30} \times 100$

⇒ $\frac{20\times 100}{30}$

⇒ $\frac{2000}{30}$

⇒ $\frac{200}{3}$

⇒ $66.6\%$

Percentage of silver bangles.

⇒ $\frac{10}{30}\times 100$

⇒ $33.3\%$

Percentage of gold bangles, Mala has = 66.6 and of silver bangles it is = 33.3

Find the value of x. 71 O (16x-2) x=

densk [106]

Answer:

x = 9

Step-by-step explanation:

m<K = 71°

arc JL = 16x - 2

m<k = ½(arc JL) => inscribed angles theorem

Substitute

71 = ½(16x - 2)

Multiply both sides by 2

71*2 = 16x - 2

142 = 16x - 2

Add 2 to both sides

142 + 2 = 16x - 2 + 2

144 = 16x

Divide both sides by 16

144/16 = 16x/16

9 = x

x = 9
