In a sixth-grade class, the ratio of boys to girls is 3:2. How many boys and how many girls could there be in this class? Is there more than one possible answer? Explain.How do you solve?

Answer 1
Answer:

Answer:

There could be 6 boys and 4 girls

There are several possible answers.

Step-by-step explanation:

Consider the provided ratio.

the ratio of boys to girls is equal to 3:2, it means that for every 2 girls in the class there will be 3 boys.

Let us assume there are 6 boys in the class.

Then the number of girls would be 4 because the ratio still have to be 3 to 2.

(6)/(4)= (3)/(2)

We can use algebra to figure this out or you can use logic.

The boys to girls ratio is 3:2, This can be written as:

(boys)/(girls) =(3)/(2)

If we multiply numerator and denominator by 2 we get.

(boys)/(girls) =(3* 2)/(2* 2)=(6)/(4)

That means for every 6 boys there are 4 girls, either way the ratio remains the same.

Similarly If we multiply numerator and denominator by 3 we get.

(boys)/(girls) =(3* 3)/(2* 3)=(9)/(6)

That means for every 9 boys there are 6 girls, and the ratio remains the same.

So there are more than one possible answer.

Hence, there are several possible answers.
Answer 2
Answer: There's an infinite number of possible answers because there might be any multiplication of 3 for boys and any multiplication of 2 for girls. So, for example:

There might be 3 boys and 2 girls.
There might be 6 boys and 4 girls.
There might be 9 boys and 6 girls.
There might be 12 boys and 8 girls.
etc...

In each case the ratio stays the same - 3 : 2.

Of course there probably can't be more than a few dozens of people in one class, but theoretically we can raise the numbers up to infinite.

A circle is divided into nine equal parts.what is the angle measure of two of those parts

Answers

Solutions 

A circle is divided into 9 equals parts. A circle is a round, therefore it has 360°. To solve the problem we have to use division.  

360° ÷ 9 = 40 

40° is the angle measure of two of those parts. 
A whole circle is 360 degrees so 360 divided by 9 equals 40 so each part is 40 degrees so 40+40=80. Your answer is 80

Are 4/16 equivalent to 0.25

Answers

0.25= 25/100

25/100 = 5/20= 1/4

4/16 = 1/4

It is equivalent

Hope I helped! (Pick me as brainliest!)
Well lets see first lets simplify the equation the 4/16 = 2/8 and 2/8 = 1/4 if we put this fraction into the decmil form it is 0.25. If you have more questions like these with numbers going into 100 what i mean is if you have 1/2 make put the demonanator into 100 so you can make that a decmil too it will be easier In all IT IS EQUIVLENT :-) hope this helped

10) 1 gallon of water for every inch of the fish's body length.
a) 2 1/2 inches long fish needs 2 1/2 gallon of water.
b) tank: l = 7 inches ; w = 5 inches; h = 7 ; volume = 7in * 5in * 7in = 245 in³
c) no. her fish tank is not large enough for the fish.
volume of 1 gallon of water is 231 in³, water needed is 2 1/2 gallon, so 5/2 * 231 in³ = 577.50 in³ volume.

11) volume = 7in * 3.5in * 1.75 in = 42.875 in³ 
weight of the brick = 0.1 pound per cubic inch ⇒ 42.875 in³ * 0.1 lb = 4.2875 pounds
weight of the gold bar = 0.7 pound per cubic inch ⇒ 42.875 in³ * 0.7 lb = 30.0125 pounds

12) l = 55cm ; w = 40cm ; h = 30 cm
volume = 55cm * 40cm * 30cm = 66,000 cm³

9/10 divided by (1/10 plus 2/5)

Answers

\boxed{ ( (9)/(10) )/(( (1)/(10) + (2)/(5) )) = ( (9)/(10) )/( (1)/(2) ) = (9)/(10) . (2)/(1) = (18^(/2))/(10^(/2)) ~\to~\boxed{ (9)/(5)} }
1.8 is the answer

1/10+2/5 is equal to 0.5

That divided by 9/10 is 1.8 or 1 8/10
