<h2>Hello!</h2>

The answer is: 15mg

0.5% means that there are 0.5 grams per 100 mL, and a 0.5 grams are equal to 500 milligrams.

So, to calculate how many milligrams will be received per injection, we need to make the following calculations:

$3mL*\frac{500mg}{100mL}=15mg$

Have a nice day!

<h2>Answer:</h2>

<u>The answer is</u><u> 15mg</u>

<h2>Step-by-step explanation:</h2>

As we know that

The percentage can be written as

0.5 % solution means 0.5 / 100 = 0.005

Now 0.5 grams are equal to 500 milligrams.

So if we want to find percentage in 3mL we will write as

= 3 x (500 mg / 100 mL)

= 15 mg

vekshin1

If I understand your question correctly, you want to know how many pounds of vegetables the zoo feeds the animals a month if its a 30 day month?

In that case it would be 23 pounds times 30 days which is 690 pounds of vegetables. SO the zoo feeds the animals 690 pounds of vegetables to the animals each month.

Is that what your asking for?

if an area can be washed at a rate of 4,900 cm2/ minute, how many square inches can be washed per hour?

Olenka [21]

Answer : 4.5 × 10⁴ square inches can be washed per hour.

Step-by-step explanation :

As we are given that an area can be washed at a rate of 4,900 cm²/min. Now we have to determine the square inches can be washed per hour.

Given conversions are:

1 cm = 0.39 in and 1 hr = 60 min

As, 1 cm² = (0.39)² in² and 1 min = 1/60 hr

So, $1cm^2/min=(0.39)^2\times 60in^2/hr$

$1cm^2/min=9.126in^2/hr$

Now we have to determine the square inches can be washed per hour.

As, $1cm^2/min=9.126in^2/hr$

So, $4900cm^2/min=\frac{4900cm^2/min}{1cm^2/min}\times 9.126in^2/hr=44717.4in^2/hr=4.5\times 10^4in^2/hr$

Therefore, 4.5 × 10⁴ square inches can be washed per hour.

It doesn't change because to add fractions, you need a common denominator. To find it, they multiplied 1/3 by 2 to make 2/6, to add to the 3/6.

Dimensions of a Box A large plywood box has a volume of . Its length is ft greater than its height, and its width is ft less tha

cupoosta [38]

Answer:

Few things are missing, they are volume of the box is 180 feet cube. Length is 9 feet greater than its height, and weight is 4 feet less than its height.

Step-by-step explanation:

Given, the volume of the box, V = 180 feet cube

Let the height of the box, h = x feet

Therefore, length is, l = ( 9+x ) feet

And width is, b = ( x-4) feet

so volume of the box is

V = l x b x h

$180= (x+9) \times (x-4) \times (x)$

$x^3 +5x^2-36x -180 =0$

Factorizing we get

(x+5)(x-6)(x+6)=0

Therefore,

x = -5, -6, 6

Now since the height of the box cannot be negative, so taking the positive value of x, we get

Height of the box, h = x = 6 feet

Length , l = ( 9+x ) = 9+6 = 15 feet

Width , b = ( x-4) = 6-4 = 2 feet
