Answer:

36hr 16min

Step-by-step explanation:

1pool/17hr - 1pool/32hr = 1 pool/xhr

1/17 - 1/32 = 1/x

Use common denomminator of 17*32 = 544

32/544 - 17/544 = 1/x

15/544 = 1/x

x = 544/15

x = 36 4/15 hr

x = 36hr 16min

Evaluate and simplify the expression when a = 4 and b = -1.

Gwar [14]

Answer:

$\frac{3}{2}$

Step-by-step explanation:

$\frac{5 - 2(a + 3b)}{2}$

substitute a = 4 and b = -1

$= \frac{5 - 2(4 + 3( - 1))}{2}$

expand and simplify the numerator

$= \frac{5 - 2(4 - 3)}{2}$

$= \frac{5 - 2(1)}{2}$

$= \frac{5 - 2}{2}$

$= \frac{3}{2}$

for a store contest four out of every 65 people who visit the store will receive a free DVD if 455 people visit the store how ma

Otrada [13]

If the rate at which they are giving the DVDs is the same then it is 4/65 or 16.25% or 0.1625.

Now just multiply 455 by the rate (4/65 or 16.25% or 0.1625) to find how many DVDs were given.

455 × (4/65) = 28

28 DVDs were given away

hope it helps :)
