Find all possible values of the expression 1/y if: .125
Answer:
The possible values for 1/y of the expression 0.125 < y < 0.25 are in the range
4 < 1/y < 8
Step-by-step explanation:
The given information are;
The range of values of y are 0.125 < y < 0.25, therefore, we have;
The boundaries of the function, y are 0.125 and 0.25
The inverse of the boundaries of the function, y are 1/0.125 = 8 and 1/0.24 = 4
Therefore;
The limits of the inverse of the function y are ;
The inequality that represents 1/y is therefore;
1/0.25 < 1/y < 1/0.125 or 4 < 1/y < 8
The possible values of 1/y for the expression 0.125 < y < 0.25 are therefore;
4 < 1/y < 8.

Step-by-step explanation:
The distance on a map between a student’s house and her job is 6 cm. On the same map, the distance between her house and her school 8 cm. The actual distance from her house to school is 12 km. If d represents the approximate distance in km between her house and her job, what is d?
Answer:
9km
Step-by-step explanation:
If the distance on the map of 8cm between her house and school is equal to 12km actual distance. This means that each cm on the map represent 1.5km in actual distance (12/8=1.5).
This means that D is equal to 9km actual distance, because if each cm represents 1.5km, then 6 cm represents 9km (6x1.5=9).
Hope this helped!
Answer:
B
Step-by-step explanation:
9 km
Changes to the cities and the environment:
1) List some ways in which the Tokugawa Shogunate strengthened Japan's economy.
2) How did rice production change?
3) Why were more roads required around Edo as the city grew?
4) Why was timber such an important resource in medieval Japan?
5) Describe the environmental policies introduced to protect forests and change the way timber was harvested.
6) Write a paragraph to explain, in broad terms, the impact that the Tokugawa shogunate had on Japan.
Answer:
Sorry i don't really know all of the question but I hope the ones I know help.
Step-by-step explanation:
The second questions answers is:
The most significant change in rice production technologies started from 2000 to 2013 and it was the introduction and adoption of new rice seed varieties. Southern rice producers increased it by planting Hybrid and non-genetically modified herbicide.
The third questions answer;
more roads were required cause Edo grew into a huge city with a lot of buildings and they needed road.
The fourth question answer; timber was important cause it was used to supply construction needed for the growing of population in the peaceful time. some places like the Shogun Leyasu and many of the Daimyo started building huge castles and templates to show their power to each other.
A sports stadium has 10000 seats, divided into box seats, lower-deck seats, and upper-devk seats. Box seats sell for 10 dollars, lower-deck seats sell for 8 dollars, and upper-deck seats sell for 5 dollars.If all the seats are sold, the total revenue for a game is 70000 dollars.The stadium has 4 times as many upper* deckseats as box seats.How many lower-deck seats are in the stadium?
Answer:
Number of box seats = 1000
Number of lower deck seats = 5000
Number of upper deck seats = 4000
Step-by-step explanation:
Let number of box seats = [tex]x[/tex]
Let number of lower deck seats = [tex]y[/tex]
Let number of upper deck seats = [tex]z[/tex]
As per question statement:
[tex]x+y+z=10000[/tex] ...... (1)
Cost for box seat = $10
Cost for [tex]x[/tex] box seats = 10[tex]x[/tex]
Cost for lower deck seat = $8
Cost for [tex]y[/tex] lower deck seats = 8[tex]y[/tex]
Cost for lower deck seat = $5
Cost for [tex]z[/tex] lower deck seats = 5[tex]z[/tex]
As per question statement:
[tex]10x+8y+5z=70000[/tex] ..... (2)
[tex]z = 4x[/tex] ..... (3)
Putting value of [tex]y[/tex] in (1) and (2):
[tex]x+y+4x=10000\\\Rightarrow 5x+y=10000[/tex] ....... (4)
[tex]10x+8 y+5\times 4x=70000\\\Rightarrow 30x+8y=70000 ..... (5)[/tex]
8 [tex]\times[/tex] (4) - (5):
[tex]10x =[/tex]10000
[tex]\Rightarrow x = 1000[/tex]
By (3):
[tex]z = 4000[/tex]
Now, by equation (1):
[tex]y[/tex] = 5000
Number of box seats = 1000
Number of lower deck seats = 5000
Number of upper deck seats = 4000
Write an equation to represent each situation. a) Blueberries are $4.99 a pound. Diego buys b pounds of blueberries and pays $14.95. b) Blueberries are $4.99 a pound. Jada buys p pounds of blueberries and pays c dollars. c) Blueberries are d dollars a pound. Lin buys q pounds of blueberries and pays t dollars.
Answer:
A) $4.99b = $14.95
B) $4.99p = $c
C) $qd = $t
Step-by-step explanation:
A) We are told that cost of blueberries is $4.99 a pound.
Now, Diego buys b pounds of blueberries and pays $14.95.
Since 1 pound costs $4.99, then b pounds will cost $4.99b
Since he paid $14.95, then the equation is;
$4.99b = $14.95
B) We are told that cost of blueberries is $4.99 a pound.
Now, Jada buys p pounds of blueberries and pays $c.
Since 1 pound costs $4.99, then p pounds will cost $4.99p
Since he paid $c, then the equation is;
$4.99p = $c
C) We are told that cost of blueberries is $d a pound.
Now, Lin buys q pounds of blueberries and pays $t.
Since 1 pound costs $d, then q pounds will cost $qd
Since he paid $t, then the equation is;
$qd = $t

Answer:
m∠E = 43°Step-by-step explanation:
AB║CD ⇒ m∠AGH = m∠CHF = 119° {corresponding angles}
m∠BGE = m∠AGH = 119° {vertical angles}
m∠BGE + m∠B + m∠E = 180° {sum of angles in triangle}
119° + 18° + m∠E = 180°
m∠E = 180° - 137° = 43°

the weights of students in a junior college are normally distributed with a mean of 100 lbs. and a standard deviation of 18 lbs. What is the probability that a student drawn at random will weigh less than 150 lbs
Answer: 0.9973 .
Step-by-step explanation:
Given: Weights of students in a junior college follows normal distribution with a mean = 100 lbs and a standard deviation =18 lbs.
Let X denotes the random variable that represents the weights of students .
Then, the probability that a student drawn at random will weigh less than 150 lbs will be :
[tex]P(X<150)=P(\dfrac{X_\mu}{\sigma}<\dfrac{150-100}{18})\\\\=P(Z<2.78 )\ \ \ \ [Z=\dfrac{X_\mu}{\sigma}]\\\\ =0.9973\ \ \ [\text{By p-value table for z}][/tex]
Hence, the e=required probability is 0.9973 .
A triangle has side lengths of (6.4c-2.5)(6.4c−2.5) centimeters, (8.7c-7.8)(8.7c−7.8) centimeters, and (6.4d-1.2)(6.4d−1.2) centimeters. Which expression represents the perimeter, in centimeters, of the triangle?
Answer:
15.1c + 6.4d - 11.5
Step-by-step explanation:
Given the following :
Lengths of the side of a triangle :
(6.4c-2.5) centimeters
(8.7c-7.8) centimeters
(6.4d-1.2) centimeters
Assume the sides Given are labeled A, B and C respectively,
The perimeter of a triangle is related vyvtge formula :
Perimeter = (A + B + C)
Perimeter = (6.4c - 2.5) + (8.7c - 7.8) + (6.4d - 1.2)
= (6.4c - 2.5) + (8.7c - 7.8) + (6.4d - 1.2)
= 6.4c - 2.5 + 8.7c - 7.8 + 6.4d - 1.2
= 6.4c + 8.7c + 6.4d - 2.5 - 7.8 - 1.2
= 15.1c + 6.4d - 11.5

Step-by-step explanation:
11) The function of the perpendicular line can be found in terms of its slope and a given point by this formula:
[tex]y-y_{o} = m_{\perp}\cdot (x-x_{o})[/tex]
Where:
[tex]x_{o}[/tex], [tex]y_{o}[/tex] - Components of the given point, dimensionless.
[tex]m_{\perp}[/tex] - Slope, dimensionless.
Besides, a slope that is perpendicular to original line can be calculated by this expression:
[tex]m_{\perp} = -\frac{1}{m}[/tex]
Where [tex]m[/tex] is the slope of the original line, dimensionless.
The original slope is determined from the explicitive form of the given line:
[tex]-2\cdot x - 5\cdot y = -19[/tex]
[tex]2\cdot x +5\cdot y = 19[/tex]
[tex]5\cdot y = 19 - 2\cdot x[/tex]
[tex]y = \frac{19}{5} -\frac{2}{5}\cdot x[/tex]
The original slope is [tex]-\frac{2}{5}[/tex], and the slope of the perpendicular line is:
[tex]m_{\perp} = -\frac{1}{\left(-\frac{2}{5}\right) }[/tex]
[tex]m_{\perp} = \frac{5}{2}[/tex]
If [tex]x_{o} = -3[/tex], [tex]y_{o} = -5[/tex] and [tex]m_{\perp} = \frac{5}{2}[/tex], then:
[tex]y-(-5) = \frac{5}{2}\cdot [x-(-3)][/tex]
[tex]y + 5 = \frac{5}{2}\cdot x +\frac{15}{2}[/tex]
[tex]y = \frac{5}{2}\cdot x +\frac{5}{2}[/tex]
The right answer is D.
12) The function of the parallel line can be found in terms of its slope and a given point by this formula:
[tex]y-y_{o} = m_{\parallel}\cdot (x-x_{o})[/tex]
Where:
[tex]x_{o}[/tex], [tex]y_{o}[/tex] - Components of the given point, dimensionless.
[tex]m_{\parallel}[/tex] - Slope, dimensionless.
Its slope is the slope of the given, which must be transformed into its explicitive form:
[tex]-8\cdot x + 5\cdot y = 89[/tex]
[tex]5\cdot y = 89 +8\cdot x[/tex]
[tex]y = \frac{89}{5}+\frac{8}{5} \cdot x[/tex]
The slope of the parallel line is [tex]\frac{8}{5}[/tex].
If [tex]x_{o} = -8[/tex], [tex]y_{o} = 1[/tex] and [tex]m_{\parallel} = \frac{8}{5}[/tex], then:
[tex]y-1 = \frac{8}{5}\cdot [x-(-8)][/tex]
[tex]y-1 = \frac{8}{5}\cdot x +\frac{64}{5}[/tex]
[tex]y = \frac{8}{5}\cdot x +\frac{69}{5}[/tex]
The correct answer is B.
14) The function of the perpendicular line can be found in terms of its slope and a given point by this formula:
[tex]y-y_{o} = m_{\perp}\cdot (x-x_{o})[/tex]
Where:
[tex]x_{o}[/tex], [tex]y_{o}[/tex] - Components of the given point, dimensionless.
[tex]m_{\perp}[/tex] - Slope, dimensionless.
Besides, a slope that is perpendicular to original line can be calculated by this expression:
[tex]m_{\perp} = -\frac{1}{m}[/tex]
Where [tex]m[/tex] is the slope of the original line, dimensionless.
The original slope is determined from the explicitive form of the given line:
[tex]-5\cdot x +9\cdot y = 49[/tex]
[tex]9\cdot y = 49+5\cdot x[/tex]
[tex]y = \frac{49}{9} +\frac{5}{9}\cdot x[/tex]
The original slope is [tex]\frac{5}{9}[/tex], and the slope of the perpendicular line is:
[tex]m_{\perp} = -\frac{1}{m}[/tex]
[tex]m_{\perp} = -\frac{1}{\frac{5}{9} }[/tex]
[tex]m_{\perp} = -\frac{9}{5}[/tex]
If [tex]x_{o} = -8[/tex], [tex]y_{o} = 1[/tex] and [tex]m_{\perp} = -\frac{9}{5}[/tex], then:
[tex]y-1 = -\frac{9}{5}\cdot [x-(-8)][/tex]
[tex]y-1 = -\frac{9}{5}\cdot x-\frac{72}{5}[/tex]
[tex]y = -\frac{9}{5}\cdot x -\frac{67}{5}[/tex]
The correct answer is A.
