What is one hundred twenty four percent

never [62]

124% as a decimal:
100% is 1 and 24% is 0.24.
So 124% is 1.24 as a decimal.

124% as a mixed number:
100% is 1 and 24% is 24/100.
To find 124% as a mixed number, simplify 24/100 and add it to 1.
24/100 = 12/50 = 6/25
So 124% as a mixed number is 1 and 6/25.

124% as an improper fraction:
To make 124% an improper fraction, just make the 1 a fraction with the same denominator as 6/25 and add.
1 = 1/1 = 25/25
25/25 + 6/25 = 31/25
So 124% is 31/25 as an improper fraction.

Hope this helps :)

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.

Picture is shown above<br>suppose that y varies directly with x, and y=12 when x=15

a_sh-v [17]

Step-by-step explanation:

Since y is directly proportional to x,

we have y = kx, where k is a real constant.

When x = 15, y = 12.

=> (12) = k(15), k = 0.8.

Therefore we have y = 0.8x.

When x = 2, y = 0.8(2) = 1.6.

The answer is y = 1.6 when x = 2.

Any actives ???can y’all please help me

kkurt [141]

Answer:

B: $2.50

Step-by-step explanation:

Step 1: form an equation

126 = 12(8 + x)

Step 2: isolate the x

126/12 = 8 + x

126/12 - 8 = x

Step 3: solve

10.5 - 8 = x

2.5 = x = raise per hour

the sitting height (from the bottom of the seat to the top of the person's head) of female drivers is normally distributed with

Sindrei [870]

Answer:

B; 50%

Step-by-step explanation:

Here, we want to calculate the percentage of women that will not fit in the driver’s seat

We proceed as follows;

We start with calculating the z-score of this;

That would be ;

(x-mean)/SD

in this case;

x = 34 inches

mean = 34 inches

SD = 1.4 inches

Thus, we have that;

(34-34)/1.4 = 0/1.4 = 0

when z-score is 0, we are at the center of the distribution

A z-score of 0 corresponds to exactly 50%
