How many line of a symmetry does a cross have?
This can depend on how the cross is made. It can either have 2 or 4 lines of symmetry.
How do you express ratios in the form 1 to n?
Ratios can be written either like this 4/5 or 4:5 both mean 4 out of 5
What is the equivalent ratios of 57?
If you mean 5 and 7 then it is 10 and 14
What ratios are equivalent to 12 3?
If you mean: 12 to 3 then it is equivalent to 4 to 1
Does it mean that 0.99gb is equal to 1gb?
No. At best, it is approximately equal.
What does it mean when two ratios form a proportion?
When two ratios form a proportion, the ratios are equal
What does it mean when the terms in a ratio are equal?
equivalent ratios
What does an sign with a cross through it mean?
not equal to
What does it mean for ratios to be proportional?
Two ratios, a:b and c:d are proportional if there is some number x such that a = cx and b = dx. Equivalently, if ad = bc (each is equal to cdx).
What is equivalent ratios mean?
ratios that r the same
What do cross products mean?
In a problem dealing with ratios, the cross produces are the product of the means, and the product of the extremes. These products are eauakl ro each other. Ratios can be written different ways. a:b :: c:d the means are the ones closest together (in the middle) their product is bc the extremes are ones fartherest apart (rt and left ends) their product is ad so .... bc = ad Ratios can also be written as fractions. a / b = c / d so bc = ad (same thing) Ex: if 3/x = 21/9 solve by using cross products 21x = 3(9) 21x = 27 x = 27 / 21 x = 1 and 2/7 or in decimal form 1.286 (rounded) There is also a cross product of vectors if you are studying them. If 2 vectors, a and b, are acting at some angle C to each other then their cross product is a x b = a b sin C , where a is the magnitude of vector a, similarly for b a x b is read as the cross product of vectors a and b, or just shortened to a cross b
What is the mathematical term the product of the mean equals the product of the extremes?
: The product of the means is equal to the product of the extremes. When you cross multiply to show 2 fractions are equivalent. Ex a/c =b/d so cross multiplying would show a x d = c x b c x b are the means a x d are the extremes Their products are equal in a proportion or equivalent fractions that is the answer and it is correct
Do different mass ratios mean different compounds?
No
How many line of a symmetry does a cross have?

What kind of factors are ratios of equal quantities?
a conversion factor conversion factors people!i mean come on i am 12 and you are probably older than me and i no the answer!woo hooo! i am smartical!;) haha conversion factor!
