Answer:  The correct option is

(D) 0.85 miles/min.

Step-by-step explanation:  We are given to find the unit rate for the following situation :

"driving 140 miles in 2 hour 45 min."

We know that

1 hour = 60 minutes.

So, we get

2 hours 45 minutes = 2 × 60 + 45 = 120 + 45 = 165 minutes.

Now, we will use the UNITARY method.

In 165 minutes, distance drove = 140 miles.

Therefore, in 1 minutes, distance drove is given by

\dfrac{140}{165}=0.848484...=0.85~\textup{miles}.

Thus, the required unit rate is 0.85 miles/minute.

Option (D) is CORRECT.

2 hr and 45 minutes is = to 165min, so do 140 divided by 165, and you will get 0.8484miles per minute, which is D

The coordinates of the vertices of AJKL are J(-5, -1), K(0, 1), and L(2, -5).
dalvyx [7]

We need slope of all lines ?

  • J(-5,-1)
  • K(0,1)
  • L(2,-5)

Slope of JK:-

\\ \sf\longmapsto m=\dfrac{1+1}{0+5}=\dfrac{2}{5}

Slope of KL:-

\\ \sf\longmapsto m=\dfrac{-5-1}{2-0}=\dfrac{-6}{0}=-3

Slope of JL

\\ \sf\longmapsto m=\dfrac{-5-1}{2+5}=\dfrac{-6}{7}

The recommended dosage for ceclor (cefaclor) is 30mg/kg to be given P.O. for a child weighing 32 lbs. Available: 125mg/5ml. How
andreyandreev [35.5K]

The child's weight in kilogram (kg) is equal to 14.5 kilogram. 2. The safe 24-hour dosage range for this child is 290 mg to 580 mg.

Given that the recommended dosage for ceclor is 30mg/kg to be given P.O. for a child weighing 32 lbs.

In order to determine the weight of the child, we would convert the value of the child's weight in pounds (lbs) to kilogram (kg) as follows:

1 pound = 0.4536 kilogram

32 pound = x kilogram

Cross-multiplying, we have: X = 32 × 0.4536 Child's weight, x = 14.5 kilogram.

Minimum range = 30 × 14.5 = 290 mg to 580 mg

Maximum range = 125 × 14.5 = 580 mg

Therefore, the safe 24-hour dosage range for this child is 290 mg to 580 mg.

Hence based on the calculations, we can infer and logically deduce that yes the dosage ordered safe because the safe single dose range is from 97 mg to 193 mg.
