Sphinxa [80]

Answer:

x/(cs)

Step-by-step explanation:

Let w represent the number of weeks we're feeding students soup.

$w\,\text{weeks}\times\dfrac{c\,\text{cans}}{\text{student}\cdot\text{week}}\times s\,\text{students}=x\,\text{cans}\\\\w=\dfrac{x}{c\cdot s}\qquad\text{divide by $c\cdot s$}$

Please help I'm very confused on this!!

Effectus [21]

Step-by-step explanation:

The formula for compound interest is

P = I (1 + r/n)^nt

where

P: the total amount of money in the account after a certain amount of time

I: the principal amount

r: the interest rate as a decimal

n: the number of times a year interest is compounded

t: the number of years passed

For Patrick:

P = 200 (1 + 0.02/12)^12*8

P = 200 (1 + 0.00166667)^96

P = 200 (1.00166667)^96

P = 200 * 1.00166667^96

P = $234.67

For Brooklyn:

P = 200 (1 + 0.04/4)^4*8

P = 200 (1 + 0.01)^32

P = 200 (1.01)^32

P = 200 * 1.01^32

P = $274.99

After 8 years, Patrick has $234.67 and Brooklyn has $274.99

The world brand of rivet placement is 11209 rivets in 9 hours and belongs to J. Mair of Ireland. If another person places 11209

Ilya [14]

Answer:

4.74 hours

Step-by-step explanation:

Given that both person have to place same number of rivets that is

11209

first person take 9 hours to complete the work

hence 1 hour work of 1st person is $\frac{1}{9}$ of total work

second person takes 10 hours to complete the same work

hence 1 hour work of 2nd person is $\frac{1}{10}$

Now if both work together then

1 hour work of both person = $\frac{1}{9} +\frac{1}{10}$ = $\frac{19}{90}$

thus working together they need $\frac{90}{19}$ hours = 4.74 hours to complete the whole work which is placing 11209 rivets
