32 people volunteers to donate blood. n dident have he health requirment so they couldent donate the rest of the volunteers dona
Vesna [10]

Answer:

the equation representing total amount of blood donated is 470(32-n)=15040-470n \ ml.

Step-by-step explanation:

Total number of volunteers = 32

number of volunteers couldn't donate blood = n.

So Number of volunteers who donated blood can be calculated by subtracting number of volunteers couldn't donate blood from Total number of volunteers.

Framing in equation form we get;

So, the number of remaining volunteers who donated blood = 32-n.

Each of these volunteers donated blood = 470 ml

Now Total Amount of Blood donated is equal to Amount each of these volunteers donated blood times the number of volunteers who donated blood.

Framing in the equation form we get;

total amount of blood donated  milliliters = 470(32-n)=15040-470n \ ml

Hence the equation representing total amount of blood donated is 470(32-n)=15040-470n \ ml.

Neporo4naja [7]

Answer:

  about 0.0143 microfarads

Step-by-step explanation:

The effective capacitance of capacitors in series is the reciprocal of the sum of their reciprocals:

  1/(1/0.02 +1/0.05) = 1/(50+20) = 1/70 ≈ 0.0143 . . . microfarads

the ratio of cars to trucks on the parking lot is 2:3 there are 24 trucks on the lot what is the total number of vehicles on the
SVEN [57.7K]

x=16

Explanation

the ratio is 2:3

it means for every 2 cars, there are 3 trucks

Now, it the total of trucks is 24,the proportion must be the same, so

Step 1

Let

x represents the number of cars for 24 trucks

\frac{\text{2 cars}}{3\text{ trucks}}=\frac{x}{24\text{ trucks}}

Step 2

solve for x

\begin{gathered} \frac{\text{2 cars}}{3\text{ trucks}}=\frac{x}{24\text{ trucks}} \\ 2\cdot24=3\cdot x \\ x=\frac{2\cdot24}{3} \\ x=\frac{48}{3} \\ x=16 \end{gathered}

Hence, the answer is 16
