What is the answer to -7+x=x/10-16

1 answer:

4 0

We first get rid of the fraction by multiplying both sides by 10

this gives us: -70+10x=x-160

subtract x from both sides

this gives us: =-70+9x=-160

add 70 to both sides

this gives us 9x=-90

divide both sides by 9

this gives us x=-10

The circle has a diameter of 16 inches. What is the area of the circle, rounded to the nearest square inch?

Ratling [72]

Statement:

The circle has a diameter of 16 inches.

To find out:

The area of the circle.

Solution:

Diameter of the circle = 16 inches.

Radius of the circle
= Diameter ÷ 2
= 16 inches ÷ 2
= 8 inches

π = 3.14

We know, area of a circle = πr² where r is the radius.

Therefore, the area of the circle
= 3.14 × (8)² square inches
= 3.14 × 64 square inches
= 200.96 square inches
= 201 square inches [rounded to the nearest square inch]

Answer:

C) 201 square inches

juin [17]

Answer:

The solution required per dosage is 3 mL and 9.175 mL of solution is required for the recommended dosage in a day.

Step-by-step explanation:

As the weight of the child is given as 27 lbs. Converting it to kgs as

1 kg =2.2042 lb

So 27 lbs=27/2.2042 kg

The weight of the kid in kg is 12.247 kg.

As the recommended dosage is 0.3 mg/kg/hour so for the weight of the kid the recommended dosage for the day is given as

Recommended dosage=0.3*12.247 =3.67 mg per day

As the concentration is given as 2 mg/5mL

So for each dose the solution is found as

Solution per dose is as Dose Value/Concentration=1.2/(2/5)=3 mL

So the solution required per dosage is 3 mL

Now for the solution required per day is given as

Solution per day is as =Dose Value/Concentration=3.67/(2/5)=9.175 mL

So 9.175 mL of solution is required for the recommended dosage in a day.
