Answer: 36.67 grams of water is added.

Step-by-step explanation:

Let the amount of water is added be 'x'.

Amount of sugar = 5 g

We need to make 12% of sugar syrup.

x grams of water is added to 5 g of sugar, to 12% of sugar syrup.

so, it becomes,

$\frac{5}{5+x}=\frac{12}{100}\\\\100\times 5=12(5+x)\\\\500=60+12x\\\\500-60=12x\\\\440=12x\\\\\frac{440}{12}=x\\\\36.67\ g=x$

Hence, 36.67 grams of water is added.

Clint is in study hall reading The hunger games. After 20 minutes, he is on page 151. After 45 minutes, he is on page 181. How m

alexdok [17]

Answer:

The number of pages had Clint read prior to study hall were <u>127 pages</u>.

Step-by-step explanation:

Given:

Clint after 20 minutes is on page 151.

And, after 45 minutes he is on page 181.

Now, to find the pages Clint read prior to study hall.

<em>The time difference = 45 minutes - 20 minutes.</em>

<em> = 25 minutes.</em>

<em>Difference between the pages = 181 - 151</em>

<em> = 30 pages.</em>

If Clint is reading each page at same speed.

Then, in 25 minutes he can read = 30 pages.

So, in 1 minute he can read = 30 ÷ 25 = 1.2 pages.

Thus, in 20 minutes he can read $=1.2\times 20$

$=24 pages.$

Now, number of pages Clint had read prior to study hall = 151 - 24

= 127 pages.

Therefore, the number of pages had Clint read prior to study hall were <u>127 pages</u>.

Law Incorporation [45]

Answer:

Ashley can type 475 more words than Tristan in 95 minutes.

Step-by-step explanation:

1. Multiply the amount of words Tristan can type per minute (57) times 95 to get 5,415 typed words in 95 minutes.

2. Multiply the amount of words Ashley can type per minute (62) times 95 to get 5,890 typed words in 95 minutes.

3. Next you subtract Tristan's total amount, 5,415 from Ashley's total amount to get the answer: Ashley can type 475 more words than Tristan in 95 minutes.
