How much will be left after 12 hours?
Guys help me please I really don’t understand this
Exponential functions are used to represent growth or decay of a substance. The amount that will be left after 12 hours is 17.42mg
How to model exponential equationsThe standard form of an exponential equation is given as:
[tex]y=a(1-r)^t[/tex]
where;
y= total amounta= starting amountr= the growth rate as a decimalt= number of growth periodsGiven the following parameters
a = 550mg
r = 0.25
t = 12
Substitute into the formula
[tex]y=550(1-0.25)^{12}\\y = 550(0.75)^{12}\\y=17.42mg[/tex]

Every time Martina orders Chinese food, she gets egg drop soup. So, she decides to learn how to make it herself. Her recipe calls for 8 cups of broth, but she can only find 32-fluid-ounce cartons at the store. How many cartons should she buy?
cartons
Answer:
2 cartons
Step-by-step explanation:
Hey! To start, we need to determine what we already know, Martine needs 8 cups worth of broth, but can only find 32-fluid ounce cartons.
Next, we need to find what we need to know, how many fluid ounces are in a cup? There are 8 fluid ounces in 1 cup!
Now, all we need to do is convert our cups to be able to find out how many cartons we need! So, to do this, we are going to multiply our number of cups by the number of fluid ounces in just 1 cup (so 8!).
8 cups x 8 fluid ounces (per 1 cup) = 64 fluid ounces
So! Martina needs 64 fluid ounces of broth to be able to create her recipe!
But, we aren't finished just yet, as we need to find how many cartons Martina needs! Like we did before, we know that there a 32 fluid ounces in 1 carton so if we have 64 fluid ounces in the recipe, all we need to do is divide 64 by 32 to find out how many cartons we need!
64 fluid ounces (8 cups worth) ÷ 32 fluid ounces (per carton) = 2 cartons
Melina needs to buy 2 cartons of broth to be able to complete her recipe.
Hope this Helps! :)

A plane traveling with the wind travels 900 miles in 5 hours. the return trip is against the wind and takes 9 hours. find the rate of the plane in still air and the rate of the wind.
Using the relation between velocity, distance and time, it is found that:
The rate of the plane in still air is of 140 mph.The rate of the wind is of 40 mph.What is the relation between velocity, distance and time?Velocity is distance divided by time, that is:
[tex]v = \frac{d}{t}[/tex]
A plane traveling with the wind travels 900 miles in 5 hours, hence:
[tex]v_a + v_w = \frac{900}{5}[/tex]
[tex]v_a + v_w = 180[/tex]
The return trip is against the wind and takes 9 hours, hence:
[tex]v_a - v_w = \frac{900}{9}[/tex]
[tex]v_a - v_w = 100[/tex]
From the first equation, we have that:
[tex]v_w = 180 - v_a{/tex]
Replacing on the second:
[tex]v_a - v_w = 100[/tex]
[tex]v_a - 180 + v_a = 100[/tex]
[tex]2v_a = 280[/tex]
[tex]v_a = 140[/tex]
[tex]v_w = 180 - 140 = 40{/tex]
Hence:
The rate of the plane in still air is of 140 mph.The rate of the wind is of 40 mph.More can be learned about the relation between velocity, distance and time at https://brainly.com/question/24316569

70% of 500=
500 divided by 10=50
50x7=350ml
Answer:
juice contained in large bottle = 500 ml
juice contained in medium bottle = 70% of large bottle
= 70 % of 500 ml
= 70/100 × 500

La distancia entre dos ciudades A y B es de 255 km. Un automovil sale de A hacia B a una velocidad de 90 km/h. Al mismo tiempo sale, otro automovil de B hacia A a una velocidad de 80 km/h. Suponiendo su velocidad constante , calcula la distancia que ha recorrido cada uno hasta el momento del encuentro
Usando proporciones, hay que:
El auto A hay recorrido 135 km.El auto B hay recorrido 120 km.¿Qué es una proporción?Una proporción es una fracción de la cantidad total.
En este problema, dos automovis, en sentidos opostos, salen al mismo tiempo. Por eso, su velocidad relativa es de 90 km/h + 80 km/h = 170 km/h.
La distancia es de 255 km, por eso, el tiempo en que se encontraran, en horas, es dado por:
t = 255/170 = 1.5h
La distancia recorrida por cada auto es dada por:
dA = 90 x 1.5 = 135 km.
dB = 80 x 1.5 = 120 km.

What is an equation of the line that passes through the point
(-2,-8) and has a slope of 3?
Answer:
y = 3x - 2
Step-by-step explanation:
Use the point-slope equation since we are given a point that the line passes through and its slope:
y - y1 = m(x - x1)
(-2, -8), m = 3
Substitute these values into the equation.
y - (-8) = 3(x - (-2)) y + 8 = 3(x + 2)y + 8 = 3x + 6y = 3x - 2The equation of the line that passes through the point (-2, -8) and has a slope of 3 is y = 3x - 2.

Hope This Helps!What is the area of ABC?
Answer:
C 10
Step-by-step explanation:
Heron's formula to calculate the area of a triangle based on 3 sides :
p (half the perimeter) = (a+b+c)/2
area = sqrt(p(p-a)(p-b)(p-c))
AB = c = sqrt(2² + 6²) = sqrt(40) = sqrt(4×10) = 2×sqrt(10)
AC = a = sqrt(2² + 4²) = sqrt(20) = sqrt(4×5) = 2×sqrt(5)
BC = b = sqrt(2² + 4²) = 2×sqrt(5)
p = 2×sqrt(5) + sqrt(10)
area = sqrt((2×sqrt(5) + sqrt(10))×sqrt(10)×sqrt(10)×(2×sqrt(5) - sqrt(10)) =
= sqrt(10×(2×sqrt(5) + sqrt(10))×(2×sqrt(5) - sqrt(10))) =
= sqrt(10×(4×5 - 10)) = sqrt(10×(20 - 10)) = sqrt(10×10) = 10
