svetlana [45]

Answer:

the length= 182 yards

Step-by-step explanation:

perimeter =550

width =93

length =x

perimeter of a rectangle = 2 length (2l)+ 2 width (2w)

550=2l+ 2(93)

550=2l+186

550-186=2l

364=2l

364/2 = 2l/2

182=l

therefore length(l) =182yards

const2013 [10]

Answer:

Isabella earn 5604.54 more money than  Gabriel

Step-by-step explanation:

As we know

Compound interest (CI) = P (1 + \frac{r}{n})^{nt}

P is the principal amount

t is the time period

n is the number of time periods

r is the rate of interest

a)  CI for  Gabriel

= 77000 (1 + \frac{3}{100*12})^{12*6} = 92165.03 dollars

b) CI for Isabella

= 77000 (1 + \frac{4}{100*4})^{4*6} = 97769.57 dollars

Isabella earn 5604.54 more money than  Gabriel
