Don't think that's possible. Once we solve using PEMDAS, 11-9 is 2, 2 x 3 is 6, but no mark between 2 and 6..

Step-by-step explanation:

(I'll be adding more answers to this answer soon!)

Alright, let's start off with the first question. :)

So, the entire length of AC is 60.

AB + BC = AC, as you can infer from the diagram.

We know that AB is 2x + 8, and AC is 3x + 7.

So,

2x + 8 + 3x + 7 = 60.

Now, we can simply evaluate for x:

Combine the like terms to get 5x + 15 = 60

Subtract 15 to get 5x = 45

Divide by 5 to get the first question's answer as x = 5 :)

------

Time for the second question!

AD is a straight angle. If an angle is straight, it measures 180 degrees. So,

AD = 180

From the diagram, we can tell that x+17 and 5x+13 add up to 180.

x + 17 + 5x + 13 = 180

Now, we can simply solve for x!

6x + 30 = 180

6x = 180 - 30 = 150

x = 150 / 6 = 25

So, we get x = 25 as the answer to the second question! :)

You are to give an injection of a drug. The dosage is 0.4 mg per kilogram of bod The concentration of the drug in vial is listed

shusha [124]

Answer:

We inject 60.9628 milliliters of dosage.

Step-by-step explanation:

Given : You are to give an injection of a drug. The dosage is 0.4 mg per kilogram of bod The concentration of the drug in vial is listed as 500 ug/ml. The patient's chart Hosts weight as 168 pounds.

To find : How many milliliters (= cc) are you to inject?

Solution :

We know that,

1 pound = 0.453592 kg,

Patient's weight = 168 pounds

Patient's weight in kg = $168\times 0.453592=76.203456$ kg

The dosage is 0.4 mg per kilogram of bod.

So, dosage of patient weight = $0.4 \times 76.2035\ mg = 30.4814\ mg$

We know, 1 micro gram = 0.001 mg

Concentration of drug is given by,

$500\ \text{micro grams/ml}= 500\times 0.001\ \text{mg/ml} = 0.5\ \text{mg/ml}$

Now we are supposed to find milliliters inject,

So, milliliters of dosage required to inject is

$d= \frac{30.4814}{0.5} = 60.9628$

Therefore, We inject 60.9628 milliliters of dosage.

Find the 10th term of the arithmetic sequence with the terms a1=15 and d=80

Alchen [17]

Answer:

The 10th term is 735

Step-by-step explanation:

The 10th term of an <em>Arithmetic Sequence </em>is given by:

$a_{10}=a_1+9d$

From the question, we were given that:

$a_{1}=15$

and

$d = 80$

We substitute these values into the above expresion to obtain:

$a_{10}=15+9 \times 80$

$a_{10}=15+720$

$a_{10} = 735$

Answer:

The slope is 2.

Step-by-step explanation:

The formula for slope is-

$\frac{y_{1} -y_{2} }{x_{1} -x_{2} } \\$

Plug in the points (6, 10) and (2, 2).

$\frac{10-2}{6-2}=\frac{8}{4} =2$
