Imagine first splitting 6 wholes up into fourths. That means that, for each whole (each 1) in 6, we're creating 4 equal slices. This gives us 4 x 6 = 24 total slices, which we call fourths. How many groups of 3 fourths (3/4) can you make out of those 24 fourths (24/4)? If we throw aside the label fourths for a minute, in general, if we have 24 things, how many groups of 3 things can we make out of those? Well, our answer there would just be 24 ÷ 3 = 8 groups.

The same thing applies to fourths. If we have 24/4, and we divide it by 3/4, we get 24 ÷ 3 = 8 groups again, so our answer is 8 3/4-pound packages.

Copy and complete the workings to find the value of each expression when m=2 and p=-4

dolphi86 [110]

Answer:

- 24

Step-by-step explanation:

4(m + 2p) ← substitute m = 2 and p = - 4 into the expression

= 4(2 + 2(- 4) )

= 4(2 - 8)

= 4(- 6)

= - 24

Gnesinka [82]

Answer:

Probability .

Step-by-step explanation:

Probability is the uncertainity of occuring or happening of something .

Probability A branch of mathematics that measures uncertainity of events using numbers

Additional Points To Look At In Probability :

An operation which can produce well defined outcome is called experimental approach .
Performing an experiment is called a Trial .
If a coin is tossed 10 times then each toss is a Trial .
If two coins are tossed samultaneously and its repeated 20 times, each samueltaneous toss of two coins is a trial .

How many liters of glycerin should be added to 12 liters of an 8% glycerin solution so that the resulting solution contains 16%

Naily [24]

1.143 liters of glycerin should be added to 12 liters of an 8% glycerin solution so that the resulting solution contains 16% glycerin.

For given question,

Let x be the quantity ( in liters ) of glycerin added to 12 liters of an 8% glycerin solution so that the resulting solution contains 16% glycerin,

Thus,

Quantity of glycerin in 12 liters + Quantity of glycerin in x

= Quantity of glycerin in resultant mixture.

⇒ 8% of 12 + 100% of x = 16% of (12 + x )

⇒ 0.08 × 12 + x = 0.16 × ( 12 + x )

⇒ 0.96 + x = 0.16 × 12 + 0.16x

⇒ 0.96 + x = 1.92 + 0.16x

⇒ x - 0.16x = 1.92 - 0.96

⇒ 0.84x = 0.96

⇒ x = 1.143 liters

Therefore, 1.143 liters of glycerin should be added to 12 liters of an 8% glycerin solution so that the resulting solution contains 16% glycerin.
