Step-by-step explanation:

Find out the how much chlorine is in the pool .

To prove

As given

The amount of chlorine in a swimming pool varies directly with the volume of water.

The pool has 2.5 milligrams of chlorine per liter of water.

i.e

2.5 milligrams of chorine = 1 litre of water

There are 8000 gallons of water in the swimming pool.

As 1 gallons = 3.78541 litre (Approx)

Now convert 8000 gallons of water in litres.

8000 gallons = 8000 × 3.78541 litre

= 30283.28 litres

Now calculate chlorine in the pool for 30283.28 litres of waters.

2.5 milligrams of chlorine = 1 litre of water

2.5 × 30283.28 milligrams of chlorine = 30283.28 litre of water

75708.2 milligrams of chlorine for 30283.28 litre of water .

(120° 3x 2x Solve for x! 120 24 360 20

Alexandra [31]

Answer:

The angles in a triangle should always add up to 180 degrees.

The four angles made by a set of intersecting lines will always add up to 360 degrees and the ones across from eachother are always the same.

This means that the triangle's unmarked angle is 60 degrees.

2*24 = 48 and 3*24 = 72 48 + 72 + 60 = 180 degrees

24 will be your correct answer.

During a field trip, 60 students are put into equal-sized groups. Describe two ways to interpret 60 ÷ 5 in this problem *

sergeinik [125]

Answer:

$x=12 groups$

This will give 5 Students each in 12 different equally sized groups

$x'=5groups$

This also shows that students can grouped in equal groups of 12 in 5 places

Step-by-step explanation:

From the question we are told that

60 children in equal sized groups

Generally interpreting $60\div 5$ can be mathematically represented as

$x=\frac{60}{5}$

$x=12 groups$

This will give 5 Students each in 12 different equally sized groups

$x'=\frac{60}{12}$

$x'=5groups$

This also shows that students can grouped in equal groups of 12 in 5 places
