You are going to first multiply 5x7 together to get 35 then you are going to add a zero before multiplying 1x7 which equals 7 then you are going to add another zero and multiply 5x2 to get 10 and lastly you are going to add 2 zeros and multiply 2x1 and you will get 2. Lastly you are going to add all the values to get 405.

Ellie’s bird feeder is shaped like a cone with a height of 24 in. and a radius of 3 in. Packages of bird seed are cylindrical an
love history [14]
The volume of seeds in the package must be equal to the volume of the feeder in order to fill it completely. The volume of the conic feeder is given by:
V(f) = (πr²h)/3
And volume of the cylindrical package is given by:
V(p) = πr²h
Equating the two and substituting values:
(π x 3² x 24)/3 = π x 6² x h
h = 2 inches

When 36 is subtracted from the square of a number, the result is five times the number. What is the positive solution?
yarga [219]

Answer:

9

Step-by-step explanation:

x^{2}  - 36 = 5x

x^{2} - 36 = 5x

x^{2} -5x = 36

9^{2} - 45 = 36

  + 45  + 45

-----------------------

81 = 81 ✅

9^{2} - 36 = 5(9)

81 - 36 = 45 ✅

Someone please please help me! I only need help on the third question. To answer the third question you need this answer which i
EastWind [94]

Answer:

3 mg

Step-by-step explanation:

<h3>Step 2 of the attachment</h3>

<em>If the patient is less than 70 years old, the loading dose is 80 Howell Units </em>

<em>per kilogram of  DM. One Howell Unit is equivalent to 0.0020 mg of pure heparin.  </em>

2. Calculate how many mg of pure heparin is in 80 Howell Units

  • 80*0.0020 = 0.16 mg per kg of DM
<h3>Step 3</h3>

<u>Let's calculate Dosing mass first, as per given formula:</u>

  • DM = LBM + (TBM - LBM)/3

As body fat is 10%,

  • LBM = 90% of TBM = 0.9*TBM

<u>As TBM is given = 40 lbs</u>

  • DM = 40 *0.9 + ( 40 - 40*0.9)/3 = 37.33 lbs

<u>Converting to kg</u>

  • DM = 37.33 Lb /2.2 = 16.97 kg

<u>Since dosing mass and dosing rate known, we can calculate loading dose:</u>

  • 16.97 kg *0.16 mg/kg = 2.7152 mg ≈ 3 mg as it is asking dose in mg

Simplify(5+2i)(1+3i)
hichkok12 [17]
(5 + 2i)(1 + 3i)

5 * 1 = 5

5 * 3 = 15i

2i * 1 = 2i

2i * 3i = 6i^2

So we have...

5 + 15i + 2i + 6i^2

5 + 17i + 6i^2

In order....

6i^2 + 17i + 5
