139 miles
explanation:
$1 → 100 cents
Here the base fee is fixed.
make equation:
$19.99 + 0.83m ↣ $135.36
0.83m ↣ $135.36 - $19.99
0.83m ↣ $115.37
m ↣ 139
Therefore she has ridden 139 miles.
What is the slope of the line y = 3?
Answer:
m = 0
Step-by-step explanation:
Using the slope intercept form. The slop is 0
Answer: m = 0
Explanation: The equation y = 3 can be thought of as y = 0x + 3.
So our line has a slope of 0 and a y-intercept of 3.
When the equation of any line reads "y = a number",
it's graph will always be a flat or horizontal line.
Whenever we have a horizontal line, the slope is always 0
Identify The slope and y-intercept Of the equation Y= -8
to get the equation of any straight line we simply need two points off of it, hmmm let's use the points in the picture below.
[tex](\stackrel{x_1}{-1}~,~\stackrel{y_1}{-8})\qquad (\stackrel{x_2}{5}~,~\stackrel{y_2}{-8}) \\\\\\ \stackrel{slope}{m}\implies \cfrac{\stackrel{rise} {\stackrel{y_2}{-8}-\stackrel{y1}{(-8)}}}{\underset{run} {\underset{x_2}{5}-\underset{x_1}{(-1)}}}\implies \cfrac{-8+8}{5+1}\implies \cfrac{0}{6}\implies 0[/tex]
[tex]\begin{array}{|c|ll} \cline{1-1} \textit{point-slope form}\\ \cline{1-1} \\ y-y_1=m(x-x_1) \\\\ \cline{1-1} \end{array}\implies y-\stackrel{y_1}{(-8)}=\stackrel{m}{0}(x-\stackrel{x_1}{(-1)}) \implies y+8=0(x+1) \\\\\\ y+8=0x+0\implies y=\stackrel{m}{0} x\underset{b}{-8}\impliedby \begin{array}{|c|ll} \cline{1-1} slope-intercept~form\\ \cline{1-1} \\ y=\underset{y-intercept}{\stackrel{slope\qquad }{\stackrel{\downarrow }{m}x+\underset{\uparrow }{b}}} \\\\ \cline{1-1} \end{array}[/tex]

What two numbers has a sum of 18 and a difference of 8?
13 and 5
let's say the two numbers are x and y
x+y = 18
x-y= 8

18+8 = 26
2x = 26
x = 13
18-13 = 5

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.
74
67
60
42
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]
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

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.

O This relationship is not a function because more than one amount of plant food remains each day. O This relationship is a function because only one amount of plant food remains each day.
Plant food is indeed dung or a mix of nitrates that are also given to soil to make it fruitful. Plant fertilizers are available in a variety of formats in the market, including water-soluble plant fertilizer, sustained-release crop fertilizer, and many others. Natural organic food is the best option for fertilizing.
Feeding the plants on a normal basis ensures optimum growth, the production of attractive blossoms and fruit, and the developing resistance to harsh weather and disease.As only one amount of plant-based foods remains every day, this connection is not a function.

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.

C. Rolling a die and getting an even number.
D. Choosing a 3 from a deck of cards, replacing it and then choosing an ace as the second card.
Answer:
C. obtaining an even number when rolling a die
Step-by-step explanation:
Two events are independent when neither depends on the other. That is, the probability that one occurs is not affected by the occurrence, or lack of occurrence, of the other event. Their joint probability is the product of their individual probabilities.
__
Among the answer choices, all describe two independent events except C. Choice C describes one (1) event, so does NOT illustrate independent events.
