Avery received $80 in cash for mowing lawns. She did the following with the $80. Put 20% of the $80 into a bank account. Spent 1

PolarNik [594]

Answer:

$48

Step-by-step explanation:

To start off, we know that Avery put 20% of the $80 in her bank account. We can figure out how much 20% of 80 is by multiplying 80 by 20% and then subtracting that number from 80. Remember to switch 20% to its decimal form (20% -> .2).

Step 1) 80 x .2 = 16

Step 2) 80 - 16 = 64

Next, we have to figure out how much 1/4 of the remaining $64 would be. We just simply divide 64 by 4 to figure out how much Avery spent.

Step 3) 64 / 4 = 16

Lastly, since we know Avery spent 16 dollars, we can subtract the 16 from 64 to get our final answer.

Step 4) 64 - 16 = 48

The gasoline gauge on a van initially read one eighth 1 8 full. when 1010 gallons were added to the tank, the gauge read three

Dmitry [639]

3/4 - 1/8 = 6/8 - 1/8 = 5/8...so 5/8 = 10 gallons

(5/8) / 10 = 1 / x
cross multiply
(5/8)(x) = (10)(1)
5/8x = 10
x = 10 * 8/5
x = 80/5 = 16 <== so it would take 16 gallons to fill the tank

Anna35 [415]

Answer:

Minimum 5 socks needs to be selected.

Step-by-step explanation:

Given that there are four different colors of socks.

So, if you pick 4 socks , in worst case it will be all four of different color.

now if you pick 5th socks it will be either of those four colors.

Hence, minimum 5 socks must be taken to ensure that a pair of matching-color socks is selected.

______________________________________________

To elaborate it more,

let four colors be red, yellow, blue , green

if you pick 5 socks, then in worst case four will be all of different color

red, yellow, blue , green but fifth will be

If red socks, then there will 1 pair of red socks
If yellow socks, then there will 1 pair of yellow socks
If blue socks, then there will 1 pair of blue socks
If green socks, then there will 1 pair of green socks

Hence. minimum 5 socks needs to be selected.

_______________________________________

In general, if you have n objects of different colors then you need to take minimum n+1 number of object to have at least two object of same color.
