Answer:

52

Step-by-step explanation:

Also Written as:

((21+22)+9)+(10*0)

Using the PEMDAS also known as Order of operations.

((21+22)+9)+(10× 0) <em>{10× 0 = 0}</em>

((21+22)+9)+(0)

Then, it will look like this below:

((21+22)+9)

Now add then all together..

21 + 9 = 30

30 + 22 = 52

Input Equation:

Input Equation:

= ((21+22)+9)+(10*0)

= ((43)+9)+(10*0)

= (43+9)+(10*0)

= (52)+(10*0)

= 52+(10*0)

= 52+(0)

= 52+0

= 52

Hence, the answer is 52.

You need a 15% acid solution for a certain test, but your supplier only ships 5% solution and 17.5% solution. If you need 20 lit
Nimfa-mama [501]

Answer:

4 liters of 5% and 16 liters of 17.5%

Step-by-step explanation:

Let quantity of 5% be x liters and of 17.5% be y liters

x+y=20 hence y=20-x

Introducing percentages

0.05x+0.175(20-x)=0.15*20

0.05x+3.5-0.175x=3

-0.125x=-0.5

x=\frac {-0.5}{-0.125}=4

Therefore, y=20-x=20-4=16

You need 4 liters of 5% and 16 liters of 17.5% to achieve 20 liters of 15% acid solution

1.How do you turn 34% into a fraction.
bearhunter [10]
For the first two, put it them over 100. So number 1 would be 34/100 or 17/50 reduced. Number 2 is 77.5/100 and since it is a decimal, I would keep it at over 100. Number 3 put 8/10 or 4/5 reduced and number 4 is different. Think of it as money and how a quarter is in relation to a dollar. You have 4 quarters in a dollar, so since you have .25%, it is 1/4.

When the movie is half over, popcorn sells for half price. Full price popcorn is $3.50, and drinks are $1.35. Determine the cost
Nady [450]
Full price of popcorn: $3.50 
Price of popcorn after half the movie: $1.75
price of drinks: $1.35 

The question is....."Determine the cost for purchasing 3 orders of popcorn and 3 drinks when the movie is half over." 

$1.75*3=$5.25
$1.35*3=$4.05

the price of the 3 orders of popcorn would be $5.25 
The price of the 3 orders of drink would be $4.05 

5.25 + 4.05 = $9.30 

In total the 3 orders of popcorn and 3 orders of drink would cost $9.30

Hope this helps! :)
