Techwiz electronics makes a profit of $35 for each MP3 player sold and $18 for each DVD player sold. Last week, Techwiz sold a c

kicyunya [14]

The combined total profit is (17x + 2502) dollars

Solution:

Profit for each Mp3 player = $ 35

Profit for each DVD player = $ 18

Let x be the number of MP3 players sold last week

Number of MP3 players = x

Last week, Techwiz sold a combined total of 139 MPS and DVD players

Total number of mp3 and dvd sold = 139

Number of DVD player = 139 - x

Write an expression for the combined total profit (in dollars) Techwiz made from MP3 and DVD players last week.

Combined total profit = Number of MP3 players x Profit for each Mp3 player + Number of DVD player x Profit for each DVD player

$combined\ total\ profit = x \times 35 + (139-x) \times 18\\\\combined\ total\ profit = 35x + 2502-18x\\\\combined\ total\ profit = 17x + 2502$

Thus the combined total profit is (17x + 2502) dollars

The container is aproximatly 1064.16 cm^2

Volume of a cylinder (area of the base* height) + area of the sphere (4 *pi * r^2)
(25*30) + (4* pi * 25) = 750 + 314.15926535898 = 1064.15926535898

An order is written for 1200 adult weight 164 pounds and is 5/9 all with a BSA of 1.9 m to the physician ordered o n c o v i n 2

Kaylis [27]

Answer:

The volume per dose that the patient should receive is 3.8 ml

Step-by-step explanation:

The physician ordered oncovin 2 mg/m² for chemotherapy treatment of a malignant tumor.

The adult's BSA (Body surface area) = 1.9m²

Hence, the amount of oncovin needed based on his body weight is:

2mg/1 m² = x mg/1.9m²

Cross Multiply

x mg = 2mg × 1.9

x = 3.8mg

We are told , oncovin is supplied:1 mg/ml

Hence:

This means

1 mg = 1 ml

3.8 mg = x ml

Cross Multiply

x ml = 3.8 ml

The volume per dose that the patient should receive is 3.8 ml
