Answer:

2,349.6‬ ml

Step-by-step explanation:

To start solving this, i realized that there was a difference in the units given and the units asked for in the answer, so I converted 2.937 grams to 2,397 mg. It is given that there are 2.145 mg of the drug in 1.716 mL, so set up the equation 2.145 / 1.716 = 2,937 / x, where x is the mL of the drug needed. Cross multiply to get 5039.892 = 2.145 x. Divide by 2.145 and get 2,349.6‬ ml

Answer:

x = 76.9

Step-by-step explanation:

Since this is a right triangle, we can use trig functions

tan theta = opp side / adj side

tan 70 = x/28

28 tan 70 = x

x=76.92936

Rounding to the nearest tenth

x = 76.9

I need help on my warm up!! pls thx!

Step-by-step explanation:

\tt{30.16 = 17.56 + 5x}

Swap the sides of the equation :

⤑ \tt{17.56 + 5x = 30.16}

We want to remove the 17.56 first.

Since the original equation is 17.56 , we are going to use the opposite operation and subtract 17.56 from both sides :

⤑ \tt{5x + 17.56 - 17.56 = 30.16 - 17.56}

Simplify. 17.56 - 17.56 = 0 on the left. 30.16 - 17.36 = 12.6 on the right.

⤑ \tt{5x = 12.6}

Then, we need to think about how to remove the coefficient 5. Since the opposite of multiplication is division , I am going to divide both sides by 5.

⤑ \tt{ \frac{5x}{5}  =  \frac{12.6}{5}}

Simplify. 5/5 = 1 on the left and 12.6/5 = 2.52 on the right. So, Our answer is x = 2.52.

\pink{ \boxed{ \boxed { \tt{Our \: final \: answer :  \underline{ \underline{ \bold{ \tt{x = 2.52}}}}}}}}

Hope I helped ! ♡

Have a wonderful day / night ! ツ
