Answer:
1000 : 199 : 271
Step-by-step explanation:
A rations a form of comparison between different variables or quantities.
We want to compare how much water, sucrose and saline solution are used to make the medicine.
The amount of water used is 1 L = 1000 mL
The amount of sucrose used is 199 mL
The amount of saline solution used is 271 mL
Therefore, the ratio of water to sucrose to saline solution is:
1000 : 199 : 271
This is the simplest form because 1000, 199 and 271 do not have any common factors.
y=2x+20; x is any integer greater than or equal to 0, and y is an integer greater than or equal to 20.
The second guitar is the answer because it has a lower amount than the first but not by alot
Answer:
None.
Step-by-step explanation:
1 - 4 + 121
= -3 + 121
= 118
121 + 1 - 41
= 122 - 41
= 81
141 - 121
= 20
1 - 21 - 1 - 41
= -20 - 1 - 41
= -21 - 41
= -62
None of the expressions have a value of -2.
Step-by-step explanation:
For the quadratic equation to have 1 repeated real solution, the discriminant b² - 4ac must be zero.
=> (-z)² - 4(z - 5)(5) = 0
=> z² - 20(z - 5) = 0
=> z² - 20z + 100 = 0
=> (z - 10)² = 0
Therefore z = 10.
