Sandra will receive $50.4 in exchange of her currency.
What is exchange rate?
" Exchange rate is the process of changing currency of one country at the rate of other country."
According to the question,
Bank of France sells U.S dollars ($) at a exchange rate of = ($1.40)/(€1)
Bank of France buys U.S. dollars at a exchange rate of = ($1.80)/(€1).
Sandra needs to exchange currency back to U.S. dollars. = €36
U.S. dollars received by Sandra in exchange currency = $ ( 1.40 × 36)

The length of a rectangle is three times the width. The perimeter is 96 cm. Find the length and width of the rectangle.
Answer:
Length = 36cm
Width = 12 cm
Step-by-step explanation:
Perimeter = all the sides added up.
Perimeter of a rectangle = L + L + W + W OR 2L + 2W
We are given that the length = 3 times the width. So L = 3W
P = 2L + 2W
96 = 2 (3W) + 2W
96 = 6W +2W
96 = 8W (divide both sides by 8)
W = 12 cm
To find the length- we know the length is 3 times the width.
So L = 3 x 12 = 36 cm
The temperature of a cup of coffee varies according to Newton's Law of Cooling: dT dt equals negative k times the quantity T minus A, where T is the temperature of the coffee, A is the room temperature, and k is a positive constant. If the coffee cools from 100°C to 90°C in 1 minute at a room temperature of 25°C, find the temperature, to the nearest degree Celsius of the coffee after 4 minutes.

Answer:
67
Step-by-step explanation:
A = 25, T(0) = 100, T(1) = 90, find T(4)
dT/dt = -k(T - A)
d(T - A)/dt = -k(T - A)
d(T - A)/(T - A) = -k dt
ln(T - A) = lnC - kt
[tex]T(t) -A=Ce^{-kt}\\T(t) = A + Ce^{-kt} = 25 + Ce^{-kt}\\T(0) = 25 + C = 100\\C=75[/tex]
[tex]T(t) = 25 + 75e^{-kt}\\T(1) = 25 + 75e^{-k} = 90\\75e^{-k} = 65\\e^{-k} = \frac{65}{75}, k = ln\frac{75}{65} = 0.1431\\T(t) = 25+75e^{-0.1431t}\\T(4) = 25+75e^{-0.1431\times4} = 67.3[/tex]

Determine the rational zeros for the function f(x)=8x^(3)-6x^(2)-23x+6.
a. -(1)/(2),(1)/(4),2
c. -1(1)/(2),(1)/(4),2
b. 1(1)/(2),(1)/(4),-2
d. -1(1)/(2),-(1)/(4),2
Answer:
Step-by-step explanation:
Rational zeros of f(x) = 8x³-6x²-23x +6 is equals to [tex]2, \frac{-3}{2} , \frac{1}{4}[/tex].
What are rational zeros?"A rational zero of a polynomial P(x) is defined as when the variable x = p/q and P (p/q) = 0 where p and q are any integers."
According to the question,
Given,
f(x) = 8x³-6x²-23x +6
Factor of 6 'p' =±1, ±2, ±3, ±6
Factor of 8 'q' = ±1 , ±2, ±4 , ±8
Using trial and error method x=2 is a common factor
Substitute x=2 in f(x) we get,
f(2) = 8(2)³ -6(2)² -23(2) +6
= 64-24-46+6
=0
(x-2) is a factor of f(x).
Divide f(x) by (x-2)
[tex]\frac{8x^{3}-6x^{2} -23x+6 }{(x-2)}[/tex]
= 8x²+10x-3
Factorize it we get,
8x²+12x-2x-3
= 4x(2x+3) - 1(2x+3)
= (4x-1)(2x+3)
For rational zeros ,Substitute f(x=(p/q)) =0
x-2=0
⇒ x=2
2x+3=0
⇒x= -3/2
= [tex]-1\frac{1}{2}[/tex]
4x-1 =0
⇒x=1/4
Hence, Option (C) is the correct answer.

con el azucar de un saco enpaco bolsas de 250 cada una.¿cuantas bolsas en paco
Esta pregunta esta incompleta
Pregunta completa
El señor Juan tiene una tienda de abarrotes y sus ventas son al mayoreo y al menudeo. La semana pasada recibió dos toneladas de azúcar en 40 sacos de 50 kg cada uno.
Con el azúcar de un saco empacó bolsas de 250 cada una.¿cuantas bolsas en paco
Answer:
200 bolsas.
Step-by-step explanation:
Se nos dice en la pregunta,
La semana pasada recibió dos toneladas de azúcar en 40 bolsas de 50 kg cada una.
Esto significa
1 bolsa = 50 kg de azúcar.
1 kg = 1000 gramos
50 kg = 50 × 1000 gramos
= 50000 gramos
Por tanto, 1 bolsa contiene = 50000 gramos de azúcar.
A partir de la pregunta anterior, se nos pregunta cuántas bolsas de azúcar obtendría si cada bolsa contuviera 250 gramos.
Por lo tanto:
50000/250 gramos
= 200 bolsas.
Por lo tanto, obtendría 200 bolsas.

It takes the window washing crew 15 minutes to wash 18 windows. Based on this, how long does it take them to wash all 24,348 windows?
Answer:
Step-by-step explanation:
34321.2 min
Step-by-step explanation:
The Burj Khalifa has in total 28601 windows. On the other hand, we are told the window-washing crew can wash 15 windows in 18 minutes. So, we can use the Rule of three to solve this problem:
If:
15 windows ---- 18 min
28601 windows ---- ?
Then:
? = (28601windows)(18min)/15windows
? = 34321.2min
To wash all 24,348 windows the washing crew needs 20290 minutes.
What is unitary method ?Unitary method a tool for first determining the value of a single unit from there we can find values of any given unit.If we multiply the value of single unit with the give data we can obtain our result.
According to the given question It takes the window washing crew 15 minutes to wash 18 windows.
∴ To wash 1 window by the window washing crew is
= 15/18 minutes.
= 5/6 minutes.
So, To wash 24348 windows the time required is
= (5/6)×24348 minutes.
= 20290 minutes.

What are the effects of low‑fat food labels on food consumption? Do people eat more of a snack food when the food is labeled as low‑fat? The answer may depend both on whether the snack food is labeled low‑fat and whether the label includes serving‑size information. An experiment investigated this question using university staff, graduate students, and undergraduate students at a large university as subjects. Subjects were asked to evaluate a pilot episode for an upcoming TV show in a theater on campus and were given a cold 24‑ounce bottle of water and a bag of granola from a respected campus restaurant called The Spice Box. They were told to enjoy as much or as little of the granola as they wanted. Depending on the condition randomly assigned to the subjects, the granola was labeled as either "Regular Rocky Mountain Granola" or "Low‑Fat Rocky Mountain Granola." Below this, the label indicated "Contains 1 Serving" or "Contains 2 Servings" or it provided no serving‑size information. Twenty subjects were assigned to each treatment, and their granola bags were weighed at the end of the session to determine how much granola was eaten. (a) How many factors and treatments are there?
Answer:
There are six factors and two treatments.
Step-by-step explanation:
We can make this conclusion because treatments in experimentation refer to something that researchers use or administer to their subjects, while factors simply refer to the category of treatments; in other words, the number of various types of treatments.
Remember, the researchers stated that "the condition [treatments] randomly assigned to the subjects", is that the granola was labeled as either "Regular Rocky Mountain Granola" or "Low‑Fat Rocky Mountain Granola," which shows that the treatments are two (Rocky Mountain Granola and Low‑Fat Rocky Mountain Granola). Summing the factors (various types/categories of treatments) gives us six factors.
