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.

Answer:
w = 120
x = 60
y = 120
z = 60
Step-by-step explanation:
w = 120 (vertically opposite angles)
sum of co interior angles is 180
⇒ w + x = 180 and x + y = 180
w + x = 180
⇒ 120 + x = 180
⇒ x = 180 - 120
⇒ x = 60
x + y = 180
⇒ 60 + y = 180
⇒ y = 180 - 60
⇒ y = 120
z = x (corresponding angles)
z = 60

Which phrase best describe the translation from the graphy y=(x+2)² to the graph of y=x²+3
Answer:
2 units right
3 units up
Step-by-step explanation:
the graph y=(x+2)² is the parent function y=x^2 translated 2 units left
the graph y=x²+3 is the parent function y=x^2 translated 3 units up
so, the translation from y=(x+2)² to y=x²+3 is:
2 units right (to get to zero)
3 units up
(you can change the order if you want, it doesn't really matter here)

Find the 66th
term in the following
arithmetic sequence
-92, -85, -78, -71, ...
Answer:
The \(66\)th term is \(363\).
Step-by-step explanation:
To find the \(n\)th term, the formula is \(7n - 99\). Since we want to find the \(66\)th term, we can plug \(n\) for \(66\). So our expression is now \(7 \cdot 66 - 99 =\) \(66\)th term. Solving this we have
\(462 - 99 = 66\text{th term}\\363 = 66\text{th term}\\\). Therefore, the \(66\)th term is \(\boxed{363}\).
Answer:
a₆₆ = 363
Step-by-step explanation:
the nth term of an arithmetic sequence is
\(a_{n}\) = a₁ + (n - 1)d
where a₁ is the first term and d the common difference
here a₁ = - 92 and d = a₂ - a₁ = - 85 - (- 92) = - 85 + 92 = 7 , then
a₆₆ = - 92 + (65 × 7)
= - 92 + 455
= 363
A computer password contains six characters but does not permit repetition of any characters (either letters or numbers). If uppercase and lowercase letters are used, how many possible passwords are there?
Answer:
\(\frac{62!}{56!}\)
Step-by-step explanation:
We can either look at all 62 characters (2 * 26 in the alphabet and 10 digits), choose 6 of them, and add the fact that we care about their order - so multiply by 6! and we get \(\binom{62}{6}\cdot 6! = \frac{62!}{6!\cdot 56!} \cdot 6! = \frac{62!}{56!}\)
Or, we can look atr all the permutations of all the characters and take into account that we DON'T care about the order of the 56 after the first six. Getting \(\frac{62!}{56!}\) immediately.

The size of a population of bacteria is modeledby the function P, where P(t) gives thenumber of bacteria and t gives the number ofhours after midnight for 0 < t < 10. Thegraph of the function P and the line tangent toP at t= 8 are shown above. Which of thefollowing gives the best estimate for theinstantaneous rate of change of P at t = 8?
Answer: The graph of the P(t) has been provided, we have to find the instantaneous slope of P(t) at t = 8:
\(Slope=m=\frac{\Delta y}{\Delta x}=\frac{y_2-y_1}{x_2-x_1}\)Therefore we need two y values and two x values, which can be obtained as follows:
\(\begin{gathered} t=8 \\ \\ \therefore\Rightarrow \\ \\ x_1=t_1=8-0.1=7.9 \\ \\ y_1=P(t_1)=P(7.9) \\ \\ x_2=t_2=8+0.1=8.1 \\ \\ y_2=P(t_2)=P(8.1) \\ \\ \therefore\rightarrow \\ \\ Slope=\frac{P(8.1)-P(7.9)}{t_2-t_1}\rightarrow(1) \\ \end{gathered}\)Equation (1) corresponds to the third, option, therefore that is the answer.
In quadrilateral ABCD seeing line A.B. is parallel to line cd which iadditional piece of information is needed to determine the ABDC is a parallelogram
Answer:
A.
Step-by-step explanation:
In a parallelogram, if one pair of opposite sides is both parallel and congruent, then the quadrilateral is a parallelogram.
Here you already know that sides AB and CD are parallel.
If sides AB and CD are also congruent, then quadrilateral ABCD is a parallelogram.
Answer: A.
Which best describes the relationship between the line that passes through the points (-6,5) and (-
2,7) and the line that passes through the points (4, 2) and (6, 6)?
Answer:
Slope passes through (-6, 5) and (-2, 7)
\(m_1=\frac{y_2-y_1}{x_2-x_1} =m_1=\frac{7-5}{-2+6}\)
\(m_1=\frac{2}{4} =\frac{1}{2}\)
Slope passes through (4, 2) and (6, 6)
\(m_2=\frac{6-2}{6-4}\)
\(\frac{4}{2} =2\)
\(m_1\times m_2 \neq -1\) \(m_1\neq m_2\)

A person earns 16000 one year and gets a 5% raise in salary. What is the new salary?
Answer:
The new yearly salary is $16,800
Step-by-step explanation:
Amount of raise.
5% = 0.05
Multiply the original salary times the percentage of the raise.
$16000 * 0.05 = $800
New salary .
$16000 + $800 = $16,800
One-step Solution
$16000+($16000 * 0.05) =$16,800

The slope of the line is -1/4, and the slope and the intercept of the line are 2 and -2, the graph of linear inequality x – 2y ≥ –12 is explained below.
The slope of the line can be found for given two points (x₁, y₁) and (x₂, y₂) such as m= (y₂ - y₁)/(x₂ - x₁). The graph of the linear inequality x – 2y ≥ –12 is the graph below:
|x | -2y|≥|-12|

There were 350 cups in a store. 140 of the cups were pink, some were yellow and the rest were green. 2/7 of the cups were green. How many yellow cups were there?
Answer:
350 cups in a store
140 of the cups were pink
some were yellow
2/7 of the cups were green
number of green cups = 2/7 x 350 = 2 x 50 = 100 cups
Number of yellow cups
= Total number of cups - (number of pink cups + number of green cups)
= 350 - (140 + 100)
= 350 - 240
= 110 cups
The New Jersey Division of Fish and Wildlife keeps track of the beaver population in the Raritan River. They tagged 42 beavers and released them. A week later, they captured 54 beavers, including 14 tagged beavers. What is a good estimate of the beaver population in the Raritan River? There are approximately beavers in the Raritan River.
Answer:ratio is 14:54 = 42:B. Beavers = 162
Step-by-step explanation:
The ratio demonstrates how often one number is multiplied by another.
The approximate number of beavers exists 162.
What is meant by ratio?The ratio demonstrates how often one number is multiplied by another. When the second number in the ordered pair, b, is not equal to 0, the ratio is expressed as a/b. An equation in which two ratios are made equal is known as a percentage.
The relationship or comparison between two numbers in the same unit to determine how much larger one number is than the other is known as a ratio.
The 42 beavers were tagged and released by the New Jersey Division of Fish and Wildlife, which monitors the beaver population in the Raritan River. After a week, they had captured 54 beavers, 14 of which were marked. There are 54 Beavers in all, and 14 Beavers have tags.
Let the ratio be 14 : 54.
As 42 tagged beavers were released.
simplifying the above equation, we get
14 × 3 : 54 × 3
= 42 : 162

A car rental company charge $50 a day and 20 cents per mile for renting a car. Let y be the total rental charge (in dollar) for a car for one day and x be the miles driven. The equation for the relationship between x and y is y = 50 + 20x How much will a person pay who rents a car for one day and drives it 100miles
Answer:$2050.
Step-by-step explanation:
To find out how much a person will pay for renting a car for one day and driving it 100 miles using the given equation, you can substitute x = 100 into the equation y = 50 + 20x and solve for y:
y = 50 + 20x
y = 50 + 20(100)
y = 50 + 2000
y = 2050
Therefore, a person who rents a car for one day and drives it 100 miles will pay $2050.

a) We can see that f(1) (the y-value when x = 1) is 3.
b) Looking at the graph, we can estimate f(-1) as about -0.25.
c) We need to find the x-values when the y-axis is at 1. We can see that there are two points at x = 0, 3.
d) Looking at the graph, we can estimate that f(x) = 0 around when x = -0.75.
e) The domain of a function is its set of x-values. We can see that f(x) spans from x = -2 to x = 4. That range in interval notation is: [-2, 4]
The range of a function is its set of y-values. We can see that f(x) spans from y = -1 to y = 3. That range in interval notation is: [-1, 3].
