At a local preschool there is a ratio of 3 boys to every 4 girls. if there are 245 total preschoolers enrolled how many are boys?

If there are 245 total preschoolers, there will be 105 boys.

Fraction of boys = 3/7

Fraction of girls = 4/7

Total number of students = 245

The number of boys will be:

= 3/7 × 245.

= 105 boys

Therefore, there are 105 boys in the school.

105

Step-by-step explanation:

Given : At a local preschool there is a ratio of 3 boys to every 4 girls.

Also,  there are 245 Total preschoolers enrolled.

Let the number of boys be 3x and the number of girls be 4x.

Then According to the question, we have

Now, the number of boys enrolled = 3(35)=105

Hence, there are 105 boys.

the answer is 9.8975

explanation:

when you multiply the "39.59" with the 25% it reduces it and shows its final discounted price. hope this !

step-by-step explanation:

hello from mrbilldoesmath!

answer:   (7x + 6y) ( 49x^2 - 42xy + 36y^2)

discussion:

in general, the factorization of a^3 + b^3 is

a^3 + b^ 3 = (a + b) ( a^2 - ab + b^2)

in our case note that 343 = 7^3 and 216 = 6^3 so the equation becomes:

343x^3 + 216y^3 = (7x)^3 + (6y)^3

if you think of a (above) as 7x and b as 6y the factorization becomes

343x^3 + 216y^3 =

((7x + 6y) (   (7x)^2 - 7x*6y + (6y)^2)   =

(7x + 6y) ( 49x^2 - 42xy + 36y^2)
