Please help. first one gets brainliest :D

Answer 1

Answer:

15 days

solution,

Given that if M1 persons can do a work in N1 days working T1 hours per day and M2 persons can do the same work in N2 days,working T2 hours per day,then

M1 N1 T1=M2 N2 T2

we have,

M1=5 , N1=16 , T1=6

M2=8 , N2=? , T2=4

Now,

$5 \times 16 \times 6 = 8 \times n2 \times 4 \\ \\ \frac{5 \times 16 \div 6}{8 \times 4} = n2 \\ n2 = 15 \: days$

hope this helps...

Good luck on your assignment..

Answer 2

Answer:

Josiah invests $360 into an account that accrues 3% interest annually. Assuming no deposits or withdrawals are made, which equation represents the amount of money in Josiah’s account, y, after x years?

y = 360(1.3)x

y = 360(0.3)x

y = 360(0.03)x

y = 360(1.03)x
