Finish this question fast

umka21 [38]

Answer:

B. -3d + 47.25

Step-by-step explanation:

Each of them has $15.75

Each spent $d

Amount each still has = 15.75 - d

Therefore, total amount the 3 of them has = 3(15.75 - d) = 3*15.75 - 3*d

= 47.25 - 3d

Which is also am equivalent of -3d + 47.25

A regular pentagon has an apothem of 3.2 and an area of 37.2 m. What

soldier1979 [14.2K]

The area of any regular polygon can be expressed as:

(ns^2)/(4tan(180/n)) where n is number of sides and s is a side length (no apothem needed :D)

37.2=5s^2/(4tan36)

s^2=(148.8tan36)/5

s≈4.65m

Help What is the graph???

marin [14]

We are given

$y=\frac{x^2-4x+3}{x^2-9}$

Vertical asymptotes:

Firstly, we will factor numerator and denominator

we get

$y=\frac{(x-1)(x-3)}{(x-3)(x+3)}$

We can see that (x-3) is common in both numerator and denominator

so, we will only set x+3 to 0

and then we can find vertical asymptote

$x+3=0$

$x=-3$

Hole:

We can see that (x-3) is common in both numerator and denominator

so, hole will be at x-3=0

$x=3$

Horizontal asymptote:

We can see that degree of numerator is 2

degree of denominator is also 2

for finding horizontal asymptote, we find ratio of leading coefficients of numerator and denominator

and we get

y=1

now, we can draw graph

A certain food has a gluten ratio of 13\,\text{mg}13mg13, start text, m, g, end text of gluten per \text{L}Lstart text, L, end t

irina [24]

Answer:

The gluten ratio in micrograms per milliliter is 13 µg/mL.

Step-by-step explanation:

Consider the provided information.

It is given that the food has a gluten ratio of $13 \frac{mg}{L}$ .

Now we need to convert gluten ratio in micrograms per milliliter

To convert mg to micro grams use the information shown below:

1 mg = 1000 micro-grams.

1 L = 1000 milliliter

Now, substitute 1 mg = 1000 micro-grams and 1 L = 1000 milliliter in the above ratio.

$13( \frac{1000 \ micro-grams}{1000 \ milliliter} )= 13( \frac{micro-grams}{milliliter})$

Hence, the gluten ratio in micrograms per milliliter is 13 µg/mL.
