The correct answer would be choices:

A and D.

A. 2 to 3 can be translated to 2/3, which is obviously the same as D. 2/3.

A and D are the same, just written in different formats. The rest are not equivalent because 2/3 does not equal 2/5 and 2/3 also does not equal 3/2.

Recycling one glass bottle can save enough energy to power an oven for 7.5 minutes. A glass bottle weighs 500 grams. Glass used
musickatia [10]

This is a units conversion problem: you have time and you want to convert that to money. Any units conversion problem involves multiplication by 1 in various forms. When you are given 7.5 min = 1 bottle = 500g, you know that (500 g)/(7.5 min) = 1 because the numerator and denominator are equal. (Of course, you are aware that 500 g = 0.500 kg.) The idea is to choose the forms of 1 that cause units you don't want to cancel, leaving only the units you do want.


6\,h\times \dfrac{0.500\,kg}{7.5\,min}\times \dfrac{60\,min}{1\,h}\times \dfrac{5\,p}{1\,kg}\\\\=\dfrac{6\cdot 0.500\cdot 60\cdot 5\,p}{7.5\cdot 1\cdot 1}=120\,p


The glass for recycling that would save enough energy to power an oven for 6 hours costs 120p.

Does anybody know this
AlexFokin [52]

Note that the measurements of the side of the squares are the same.

Area = base x height

Area = length x width

The area given is 400

Root 400 to get the length of the sides

√400 = 20

20 in. is your side measurement

hope this helps

Tju [1.3M]

Answer:

(C) 32

Step-by-step explanation:

This is a problem of Permutation and Combination, not probability.

This clarification is given because most questions like this are on Probability and Statistics.

The researcher has recruited 8  participants and must divide them into two groups of 4 people each.

So there's:

GROUP A - Placebo Group

GROUP B - Experimental Group

Since the experiment is on humans - distinct objects - they will have distinct identities. Assume the 8 participants are lined up according to identities 1,2,3,4,  5,6,7,8

[2+2+2+2  +2+2+2+2] × 2 = 16×2 = 32

Solve 2cos^2x+5cosx+2=0
Nuetrik [128]
2cos^2x+5cosx+2=0\\&#10;x\in\\&#10;\Delta=b^2-4ac\\&#10;\Delta=9\\&#10;\sqrt{\Delta}=3\\&#10;cosx=1\\&#10;or\\&#10;cosx=-6\\&#10;-6\notin\\

Then using trygonometric table or a graph we read that:
cosx=1\Leftrightarrow(x)=0

Period of cosinus function = 2π
So the last answer is x=0+2k\pi\\
