PLEASE help

Inessa [10]

Answer:

$\left(\dfrac{3}{4}\right)^{14}$

Step-by-step explanation:

Given expression:

$\left(\left(\dfrac{3}{4}\right)^4 \times \left(\dfrac{3}{4}\right)^3\right)^2$

$\textsf{Apply the product rule of exponents} \quad a^b \cdot a^c=a^{b+c}:$

$\implies \left(\left(\dfrac{3}{4}\right)^{4+3}\right)^2$

$\implies \left(\left(\dfrac{3}{4}\right)^{7}\right)^2$

$\textsf{Apply the power of a power rule of exponents} \quad (a^b)^c=a^{bc}:$

$\implies \left(\dfrac{3}{4}\right)^{7\times 2}$

$\implies \left(\dfrac{3}{4}\right)^{14}$

At the dance, the ratio of the number of girls to boys is 7:5. If there are 36 more girls than boys, how many girls were at the

katrin [286]

9514 1404 393

Answer:

126 girls
90 boys

Step-by-step explanation:

The difference is 7-5 = 2 "ratio units", corresponding to a difference of 36 dancers. Then each "ratio unit" stands for 36/2 = 18 dancers.

There are 7×18 = 126 girls.

There are 5×18 = 90 boys.

_____

You could solve this by writing some equations:

g/b = 7/5

g -b = 36

Then you could substitute for g:

(36+b)/b = 7/5

36/b +1 = 2/5 +1 . . . . expand the fractions

36/b = 2/5 . . . . . . . . . subtract 1

b = (5/2)(36) = 90 . . . multiply by 5/2b

g = 36+90 = 126
