Your doctor prescribes you to take 400 milligrams of medicine every 8 hours. How many ounces of medicine do you take in a day?

Answers

1,200 milligrams...thats the answer

Answer:

.042 ounces

Step-by-step explanation:

First, calculate how many mg you take in a day. 24/8=3, and 3*400=1200, so assuming you don't miss any, you would take 1200 milligrams in a day. You can change this to 1.2 grams. The conversion rate from grams to ounces is about .035, so you would get 1.2*.035. That makes .07*.6, which is 42 with 3 decimal points to the left. That's about .042 ounces.

Camacho is buying a monster truck. The price of the truck is x dollars, and he also has to pay a 13% monster truck tax. Which of the following expressions could represent how much Camacho pays in total for the truck? Choose 2 answers: (Choice A) (1+0.13)x (Choice B) 13/100x (Choice C) 14x (Choice D) 1.13x (Choice E) 13x+x

Answers

Answer:

Option A and D are the correct answer.

Step-by-step explanation:

Price of truck = x

Tax for the truck = 13 %

We need to find how much Camacho pays in total for the truck.

$\texttt{Amount Camacho need to pay }=x+(13)/(100)* x\n\n\texttt{Amount Camacho need to pay }=x+0.13x=(1+0.13)x=1.13x$

Option A and D are the correct answer.

A and E are the two expressions that work

PLEASE HELP!! WILL THANK YOU AND MARK BRAINLIEST!!Triangle ABC has vertices A (0,7), B (7,3), and C (1,4): Under the transformation rule, (x,y) —> (x-3,y-4), A’ would be (-3,3).

True

False

Answers

Answer:

True

Step-by-step explanation:

Since the rule is (x, y) ---> (x - 3, y - 4), you would subtract 3 from 0 (the x value of A) which would be -3. Then subtract 4 from 7 (the y value of A), which would be 3. So the answer would be true, that A' would be (-3, 3).
