A certain food has a gluten ratio of 13mg per L of the food.what is the gluten ratio in micrograms per milliliter? PLEASE HELP M
AlekseyPX
Given:
The gluten ratio is 13 mg per L of food.

Note that
1 L = 1000 mL (milliliter)
1 mg = 10⁻³ g
1 μg = 10⁻⁶ g
Therefore
1 mg = 1000 μg

The gluten ratio is
(13  \frac{mg}{L} )*( 1000   \frac{\mu g}{mg} )*( \frac{1}{1000} \frac{L}{mL}  )=13 \frac{\mu g}{mL}

Answer:  The gluten ratio is 13 μg/mL

Ariel is filling a giant beach ball with air. The radius of the beach ball is 303030 cm. What is the volume of air that the beac
AVprozaik [17]

Answer:

The volume of air that the beach ball will hold is 36,000 \pi\ cm^{3}

Step-by-step explanation:

we know that

The volume of a sphere ( a giant beach ball with air) is equal to

V=\frac{4}{3}\pi r^{3}

we have

r=30\ cm

V=\frac{4}{3}\pi (30^{3})

V=36,000 \pi\ cm^{3}

A rectangle is twice as long as it is wide. If its length and width are both
puteri [66]

Answer:

a rectangle is twice as long as it is wide . if both its dimensions are increased 4 m , its area is increaed by 88 m squared make a sketch and find its original dimensions of the original rectangle

Step-by-step explanation:

Let l = the original length of the original rectangle

Let w = the original width of the original rectangle

From the description of the problem, we can construct the following two equations

l=2*w (Equation #1)

(l+4)*(w+4)=l*w+88 (Equation #2)

Substitute equation #1 into equation #2

(2w+4)*(w+4)=(2w*w)+88

2w^2+4w+8w+16=2w^2+88

collect like terms on the same side of the equation

2w^2+2w^2 +12w+16-88=0

4w^2+12w-72=0

Since 4 is afactor of each term, divide both sides of the equation by 4

w^2+3w-18=0

The quadratic equation can be factored into (w+6)*(w-3)=0

Therefore w=-6 or w=3

w=-6 can be rejected because the length of a rectangle can't be negative so

w=3 and from equation #1 l=2*w=2*3=6

I hope that this helps. The difficult part of the problem probably was to construct equation #1 and to factor the equation after performing all of the arithmetic operations.
