1 litre of 10% solution contains 100mL of iodine
1 litre of 90% solution contains 900mL of iodine
Mixing them will produce 2 litres of solution containing 1000mL of iodine which is 50% iodine.
To produce 8 litres of 50% iodine they can mix 4 litres of 10% and 4 litres of 90%
Answer:
endpoint is (29, -13)
Step-by-step explanation:
Formula for midpoint is ![(\frac{x_{1} + x_{2} }{2} ,\frac{y_{1} + y_{2} }{2} )](https://tex.z-dn.net/?f=%28%5Cfrac%7Bx_%7B1%7D%20%2B%20x_%7B2%7D%20%7D%7B2%7D%20%2C%5Cfrac%7By_%7B1%7D%20%2B%20y_%7B2%7D%20%20%7D%7B2%7D%20%29)
So, let
be the coordinates of the endpoint you are looking for.
and
= (10, -3)
![\frac{7 + y_{2} }{2} = -3](https://tex.z-dn.net/?f=%5Cfrac%7B7%20%2B%20y_%7B2%7D%20%7D%7B2%7D%20%20%3D%20-3)
-9 +
= 20 7 + ![y_{2} = -6](https://tex.z-dn.net/?f=y_%7B2%7D%20%20%3D%20-6)
![y_{2} = -13](https://tex.z-dn.net/?f=y_%7B2%7D%20%20%3D%20-13)
endpoint is (29, -13)
Answer:
$15
Step-by-step explanation:
Given that :
Aunt's distance = 120 miles
Miles per gallon of Olivia's car = 24 miles per gallon
Cost of gasoline = 3 per gallon
Cost of gasoline for the trip :
(Aunt's distance / miles per gallon) * cost of gasoline per gallon
(120 miles / 24 miles per gallon) * 3
5 * 3 = $15
Cost of gasoline for the trip = $15
Answer:
c. 3680
Step-by-step explanation:
In 2010, the population was 8000.
In 2014, it increased by 15%.
Population in 2014 :
= 8000 + 15/100×8000
= 8000 + 1200
= 9200.
Now, 2/5 of the population was age 12 or under.
= 2/5 × 9200
= 2×1840
= 3680
Answer - c) 3680
Answer:
The temperature would be 55 degrees fahrenheit
