Answer:

825

Step-by-step explanation:

Let the number of students who participated in the sport be x, which is equivalent to 0.825

The total number of students in the school is equivalent to 1

Expressing mathematically,we obtain

0.825:x=1:1000

\implies  \frac{0.825}{x}= \frac{1}{1000}

By cross multiplying we obtain,

x=0.825 \times 1000

We finally simplify to arrive at

x=825

Hence the number of students who participated in the sport is 825

Answer:

825 students

Step-by-step explanation:

When we say 0.825 students participate, we are actually meaning that 82.5% of the students are participating.

<u>Note:</u> to get decimal to percentage, we move the decimal 2 places right

In total there are 1000 students, so we need to find 82.5% of them to find the number who participate in a sport.

<u>Note:</u> To get this, we need to multiply 1000 by the DECIMAL of 82.5%, which is 0.825.

Hence, we have 1000 * 0.825 = 825 students

He should increase the length and width by a factor = sqrt 3.

so new length should be 78* sqrt3 = 135.1 - that is increase of 58.1 ft
and new width should be 65 * sqrt3 = 112,58  = increase of 47.58 ft

Analyzing a Function The population of bobcats in northern Arizona since 2008 can be modeled using the function b(t) = –0.32t2 +
bulgar [2K]

"b" represents the population of bobcats.

1) "t" represents the number of years after 2008.

2) The domain (t) starts at 0 (which is the year 2008) ⇒  t ≥ 0

3) The range (b) starts when t = 0. b =-0.32(0)² + 2.7(0) + 253 ⇒ b ≥ 253

4) The graph is discrete because the population must be in whole numbers.
