The isolated value of h is found to be V/πr²

The three-dimensional solid shape of a cylinder is made up of two parallel bases connected by a curved surface. These bases have the shape of a spherical disc. The axis of the cylinder is a line drawn through the centre or connecting the centres of two circular bases. The density of a cylinder is determined by its volume, which represents how much material may be immersed in it or carried inside of it. The formula πr²h, where r is the radius of the circular base and h is the height of the cylinder, determines the volume of a cylinder. Any substance that can fill the cylinder consistently with liquid or another material may be used as the component.

According to given formulae:

V=πr²h

On dividing both side with πr² we get

⇒V/πr²=πr²h/πr²

(Solving R.H.S)

⇒h=V/πr²

Therefore, the value of h in the given question is V/πr²

Step-by-step explanation:

Answer:

The flow rate of dopamine per hour is 15 mg and the duration is 9.3 hours.

Step-by-step explanation:

It is given that A solution consisting of 70 mg of dopamine in 70 mL of solution is administered at a rate of 15 mL/hr.

A solution consisting of 182 mg of dopamine in 26 mL of solution is administered at a rate of 10 ​mL/hr.

Now, Let's calculate the flow rate of dopamine per hour;

=> Flow rate of dopamine per hour = (70 × 15)/70

=> Flow rate of dopamine per hour = 1050/70

=> Flow rate of dopamine per hour = 15 mg

Further, let's calculate how much the solution should last for a patient that is prescribed to receive 140 mg of dopamine;

=> Prescription = 140 mg

=> Flow rate of dopamine per hour = 15 mg

=> Duration = Prescription/Flow rate of dopamine per hour

=> Duration = 140/15

=> Duration = 9.3 hours

Therefore, the flow rate of dopamine per hour is 15 mg and the duration is 9.3 hours.

Applying the product rule for exponent numbers, 2⁴ . 2⁵ = 2⁴⁺⁵ = 2⁹

Recall the rules of exponent operations:

Note that the first 3 rules use the same base. If there are more than 1 base number, then group the exponent that have the same base first.

Example:

[tex](2^{3}.3^{-2}) : (2^{-3}.3^{2})=( 2^{3}:2^{-3}).(3^{-2}:.3^{2})[/tex]

Tips: To simplify exponent numbers, sometimes it is useful to modify the base whenever possible.

Example:

8².2⁻⁵ = (2³)². 2⁻⁵ = 2⁶. 2⁻⁵ = 2⁶⁻⁵ = 2¹ = 2

y = 2 + 0.0357x shows the relationship between the height of the lemons and days, it will take 16 weeks for the lemon tree to reach 6ft.

Day 0 the plant is 2ft

Every 7 days the plants increase by 3 inches

Recall that, 1 inch = 0.0833 feet

Therfore  3 inches = 3 × 0.0833 = 0.2499ft

The plant increases in  by 0.2499/7 daily

0.25/7 = 0.0357

Let x be the days and the y be plant height, the plant height and the number of days can be related by

y = 2 + 0.0357x

Days (x)

b) when the tree will by 6ft, y = 6ft

      y = 2 + 0.0357x

      6 = 2 + 0.0357x

Collect like terms

6-2 = 0.037x

4 = 0.0357x

x = 4/0.0357

x = 112.04 days

x = 112 days

Converting it to weeks 112/7 = 16 weeks, it will take 16 weeks for the plant to grow to 6ft.

When 4 nightstands are sold the profit is $1800 since the number of nightstands sold is directly proportional to the profit.

The profit is defined as difference between the cost price and sell price for a product.

A directly proportional relationship means that if two variables x and y are proportional to one another then there exist a constant k such that x = y × k .

The graph of a directly proportional equations is a straight line passing through the origin.

Given that the profit is $900 for 2 sold nightstands, $3600 for 8 night stands and $4500 for 10 sold nightstands.

Now this relationship is directly proportional.

So the constant is given by k=900/2=4500/10=3600/8=450

Hence the profit for selling 4 night stands is 450 × 4 =$1800

The result of simplifying each number 1000⁴/₃ / 100³/₂ using the exponent rules is: 10

To solve this exercise we have to resolve algebraic operations following the exponent rules.

(1000⁴/₃) / (100³/₂)

Base: 1000 = 10³

Base: 100 = 10²

As 1000 is the same as 10³ and 100 is the same as 10², we get:

(10³)⁴/₃ / (10²)³/₂

Using the power of a power rule that indicates that: the exponent result will be the multiplication of these exponents, we have:

10³*⁴/₃ / 10²*³/₂

10¹²/₃ / 10⁶/₂

10⁴ / 10³

Using the quotient rule that indicates that: the exponent result will be the subtraction of these exponents, we have:

10⁽⁴⁻³⁾

Length of segment 'cd' = 12 units

Given:-

'ol' is the mid-point of line segment 'cd'

'cl' = 13x + 8

'ld' = 23x - 4

We have to find the length of segment 'cd'.

Since the point 'ol' is the median to the segment cd then two expressions given 'cl' and 'ld' must add up to 'cd'.

'cd' = 'cl' + 'ld'

'cd' = (3x - 6) + (7x - 22)

'cd' = 10x - 28

- To determine the value of x we can also say that 'cl' and 'ld' must be equal because 'ol' is the common mid-point on the line segment 'cd'. So we can write:

'cl' = 'ld'

3x - 6 = 7x - 22

22  - 6 = 7x - 3x

       16 = 4x

        x = 4 units

- Now substitute the value of x in the expression developed for 'cd' as follows:

'cd' = 10x - 28

'cd' = 10 × 4 - 28

cd = 40 -28

'cd' = 12 units.

Therefore, the length of segment 'cd' is 12 units.

There will be a 6% rise using the 0.9646 multiplier, then a 9% reduction.

Simply said, a multiplier is a factor that increases the basic value of another object. For example, a 2x multiplier would double the initial value. On the other hand, a multiplier of 0.5x would actually cut the basic amount in half. In finance and economics, multipliers come in a wide variety.

Say that Number is 100N.

growth of 6%

= (6/100)100N

= 6N

Number following reduction: 100N + 6N = 106N

9% lessening

= (9/100)106N

=954N/100

= 9.54N

Final result after reduction = 106N - 9.54N

=96.46N

=9646N/100

= 9646 * 100N/100 * 100

= 9646 * 100N/10000

= 0.9646 * 100N

There will be a 6% rise using the 0.9646 multiplier, then a 9% reduction.

According to the solving Mrs. Weatherford spends 15 percent of each weekday  25 hours and 20 minutes in her car.

A % is a relative figure that represents the hundredth part of any amount. One percent (symbolized 1%) is one hundredth part; consequently, 100 percent denotes the complete amount and 200 percent defines twice the supplied amount.

The most fundamental use of percentages is really to compare one number to another, with the second number rebased to 100. Assume we want to know the number among employed females as both a percentage of all employees.

Mrs. Weatherford drives 15% of the time during the week.

We know that:

1 week  = 7days

1day  = 24 hours

So 7 days  = 7 x 24

                  = 168 hours

Mrs. Weatherford drives 15% of the time during the week.

So,

Naomi's burger shack sold a total of 484 hamburgers today.

three times as many hamburgers were sold without cheese as were sold with cheeseburgers

how many cheeseburgers were sold?

according to the question

Hamburgers (H) + cheeseburgers (C) = 484

C + H =  484

H = 3C

we can solve these equation

C+ 3C = 484

4 C= 484

C = 121
