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

I need Help plsssss!!!!!

laiz [17]

Answer:

2x - 3

x - 9

Step-by-step explanation:

The root of a problem is the x value that makes the equation equal to zero.

If the factored form of the equation is (2x-3)(x-9) that means if either 2x - 3 or x - 9 is equal to zero, the entire equation will equal zero, because zero times any number is equal to zero.

Therefore you must solve for (2x-3)=0 and (x-9)=0
