48 miles per hour! Just double 30 minutes to get an hour, and double 24 as well which equals 48.
Answer:
About 13 ml
Step-by-step explanation:
The child weighs 56 lbs. We need to first convert the weight of the child from lbs to kg so that we can know the amount of drug in mg is needed to be given to the child.
1 lb = 0.4536 kg
![56\ lbs=56\ lbs*\frac{0.4536\ kg}{1\ lb} =25.4\ kg\\\\](https://tex.z-dn.net/?f=56%5C%20lbs%3D56%5C%20lbs%2A%5Cfrac%7B0.4536%5C%20kg%7D%7B1%5C%20lb%7D%20%3D25.4%5C%20kg%5C%5C%5C%5C)
Therefore the amount of mg needed to be administered to the child = 50 mg/kg * 25.4 kg = 1270 mg
Since the oral suspension is in 100 mg per ml, hence:
Amount per dose = 1270 mg / (100 mg/ml) = 12.7 ml ≅ 13 ml
The child should be given 13 ml for each dose.
The volume of soup in the cylindrical can is 100.48 inches cube.
<h3>How to find the volume of a cylindrical can?</h3>
We have to find the volume of the soup in a cylindrical can of height 8 inches and 4 inches across the lid.
The volume of the soup is the volume of the cylindrical can.
Therefore,
volume of the cylindrical can = πr²h
where
- r = radius of the cylinder
- h = height of the cylinder
Therefore,
h = 8 inches
r = 4 / 2 = 2 inches
volume of the soup in the cylindrical can = πr²h
volume of the soup in the cylindrical can = π × 2² × 8
volume of the soup in the cylindrical can = π × 4 × 8
volume of the soup in the cylindrical can = 32π
Therefore,
volume of the soup in the cylindrical can = 32 × 3.14
volume of the soup in the cylindrical can = 100.48 inches³

Answer:
![x=\frac{-9}{7}](https://tex.z-dn.net/?f=x%3D%5Cfrac%7B-9%7D%7B7%7D)
![y=\frac{-17}{7}](https://tex.z-dn.net/?f=y%3D%5Cfrac%7B-17%7D%7B7%7D)
Step-by-step explanation:
We have been given the equation:
![3x-2y-1=0](https://tex.z-dn.net/?f=3x-2y-1%3D0)
And ![y=5x+4](https://tex.z-dn.net/?f=y%3D5x%2B4)
Second equation can be rewritten as:
![5x-y=-4](https://tex.z-dn.net/?f=5x-y%3D-4)
We will solve the equations:
(1)
(2)
Multiply equation (1) by 5 and equation (2) by 3 we get:
(3)
(4)
Now, subtract (4) from (3) we get:
![-7y=17](https://tex.z-dn.net/?f=-7y%3D17)
![y=\frac{-17}{7}](https://tex.z-dn.net/?f=y%3D%5Cfrac%7B-17%7D%7B7%7D)
Now substitute
in equation (1) we get:
![3x-2{\frac{-17}{7}}=1](https://tex.z-dn.net/?f=3x-2%7B%5Cfrac%7B-17%7D%7B7%7D%7D%3D1)
![3x+\frac{34}{7}=1](https://tex.z-dn.net/?f=3x%2B%5Cfrac%7B34%7D%7B7%7D%3D1)
![21x=-27](https://tex.z-dn.net/?f=21x%3D-27)
![x=\frac[-27}{21}](https://tex.z-dn.net/?f=x%3D%5Cfrac%5B-27%7D%7B21%7D)
![x=\frac{-9}{7}](https://tex.z-dn.net/?f=x%3D%5Cfrac%7B-9%7D%7B7%7D)
