in 1995, diana read 10 english books and 7 french books. in 191!6, she read twice as many french books as english books. if 60%

Diana read 6 English books and 32 French books in 1996.

For given question,

Let the number of English books = x

And the number of French books = y

In 1995 Diana read 10 English books and 7 French books.

⇒ x = 10 and y = 7

In 1996, she read twice as many French books as English books.

So, we get an equation,

⇒ y = 2x

Also, 60% of the books that she read during the 2 years were French

Let m be the total number of books she read in 2 years.

⇒ y = 60 percent of m

⇒ y = 0.6(m) ............(i)

and x = 0.4(m)

We don't know the exact amount of books read in 1996.

m = 10 + 7 +x +2x

m = 17 + 3x

We can write equation (i) as,

⇒ 0.6(m) = 7 + 2x

⇒ 0.6(17 + 3x) = 7 + 2x

⇒ 10.2 + 1.8x = 7 + 2x

⇒ 10.2 - 7 = 2x - 1.8x

⇒ 3.2 = 0.2x

⇒ 3.2/0.2 = x

⇒ 16 = x

So, she read 16 English books

And 16 × 2 = 32 French books

Total books: 16+32= 48 books in 1996

Therefore, Diana read 6 English books and 32 French books in 1996.

In bowling, knocking down all of the pins with the first ball of a frame is called a strike. Roni is practicing bowling and gets

Nesterboy [21]

Answer:

$0.50 \leq \frac{x+2}{x+10}\\$

At least 6 strikes

Step-by-step explanation:

The required numerical data is missing from the question. In the original question, Roni gets a strike 2 out of 10 times and her goal is to have a minimum strike rate of 50%. The number of consecutive strikes required is given by the following inequality:

$0.50 \leq \frac{x+2}{x+10}\\$

Solving the inequality:

$0.5x+5 \leq x+2\\3\leq0.5x\\x\geq6$

Roni needs at least 6 strikes.

After 6 strikes, she would have 8 out of 16, which equals exactly 50%.
