Ben scores 56 out of 79 on a maths test what is his score as a percentage
to 1 decimal place?

56/79=.7088

Step-by-step explanation:

We are given Ben score 56.

Total marks out of which 65 Ben got is =79 marks.

We need to find, 56 is what percentage of 79.

to find the percentage, we need to divide getting marks from total marks and then multiply by 100.

On dividing 56 by 79 we get 0.70886..

to multiply it by 100, we get

0.70886..× 100 = 70.886.

round it to 1 decimal place.

Therefore,  70.886 ≈ 70.9 %.

Ben's score is 70.9%.

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)

(a + b) (a^2 - a b + b^2)

27/4x^6 y^8

step-by-step explanation:

4(3x^2y^4)^3 (2x^3y^5)^4

=

108x^6 y^12 /16x^12 y^20

=

108 /16x^6 y^8

=

27 /4x^6 y^8
