Answer:

K = 75000 Joules

Step-by-step explanation:

K = 1/2mv^2

K = 1/2(1500)(10^2)

K = 1/2(150000)

K = 75000 Joules

104 pounds requires 156 milligrams of medicine what is the weight of a patient who requires 207 milligrams of medicine
Lubov Fominskaja [6]

Answer:

138 pounds

Step-by-step explanation:

Let the required weight of the patient be x pounds.

We have that,

156 milligrams of medicine is required for a patient weighing 104 pounds.

Then, 207 milligrams of medicine will be required for a patient having weight as shown below,

Weight of the patient = \frac{104 \times 207}{156}

i.e. x = \frac{21528}{156}

i.e. x = 138

Hence, the patient needing 207 milligrams of medicine will have the weight 138 pounds.

wolverine [178]

Answer:

Answer:

4.8 gigabytes

Step-by-step explanation:

Let the number of gigabytes of data = x

Xavier pays a flat cost of $44 per month and $3 per gigabyte. He wants to keep his bill at $58.40 per month.

The above expression above is represented by the equation:

$44 + $3 × x = $58.40

44 + 3x = 58.40

Solving for x

Subtract 44 from both sides

44 - 44 + 3x = 58.40 - 44

3x = 14.4

x = 14.4/3

x = 4.8 gigabytes
