Quantity of water used to make a medicine :-
This quantity of water required to make a medicine = 1000 ml
Quantity of sucrose used to make a medicine = 150 ml
Quanity of saline solution used to make a medicine = 600 ml
The quantity of water to sucrose to saline solution needed to make a medicine as a ratio :-
Cutting each common zero in this ratio, we get :-
Dividing each number in the ratio by 5, we get the ratio :-
Since, the three numbers in this ratio doesn't have any common factors we can conclude that we have found out the simplest form of the ingredients needed to make the medicine .
Therefore, the ratio of water to sucrose to saline solution needed to make a medicine = 20:3:12
Answer:
Step-by-step explanation:
Let x represent his average walking speed.
If the average speed on the bike is 8 mph faster than his walking speed,it means that his biking speed is (x + 8) mph
Distance = speed × time
Alex returns a bike to a friends house from his own house in 1/2 hour. This means that the distance covered is
0.5(x + 8)
He walks back over the same route in 1.5 hours. This means that the distance covered is
1.5x
Since the distance covered is the same, then
1.5x = 0.5(x + 8)
1.5x = 0.5x + 4
1.5x - 0.5x = 4
x = 4 mph
Therefore, the distanceof Alex's house from his friend's house is
4 × 1.5 = 6 miles
I believe the correct answer from the choices listed above is option B. The variable y is the independent variable here and x is the dependent variable so the function can be represented as f(y). The function should be written as:
<span>x = f(y) = 7 + y</span>
Answer:
From the circumference you can determine the radius. Once you have the radius, you calculate the area as πr^2
The answer will be
A=201cm^2
Step-by-step explanation:
The x-axis is the first phrase where 1 unit to the right of y-axis, meaning 1 unit to the right of 0, which means the x-axis is 1.
the y-axis is the second phrase where 7 units above x-axis, which means 7 uniys above 0, which means the y-axis is 7
i am not sure what ordered pair means though...so i will just give you x-axis and y-axis:
x-axis=1 y-axis=7
