Answer:
Option D. 5 EE 6 ÷ 6.6 EE 4
Step-by-step explanation:
Data obtained from the question include the following:
Area of land purchased = 6.6×10^4 square miles
Cost = $ 5×10^6
To determine the key strokes on a calculator which will give the cost the
United States paid for each square mile of Florida, let us calculate cost of 1 square mile.
This can be obtained as follow:
6.6×10^4 sq mile = $ 5×10^6
Therefore,
1 sq mile = $ 5×10^6 ÷ 6.6×10^4
In calculator, the key strokes will be:
5 EE 6 ÷ 6.6 EE 4

the price of a jacket was slashed from RS 960 to RS 816 .then the rate of discount offered is 10 percentage
Answer:
15%
Step-by-step explanation:
Question:
The price of a jacket was slashed from Rs.960 to Rs.816.Then the rate of discount offered is
Solution
Original price= Rs.960
Discount price= Rs.816
Difference in price=Original price - discount price
=Rs. 960 - Rs. 816
=Rs. 144
Percentage discount= Difference in price / Original price × 100
=Rs. 144 / Rs. 960 × 100
=0.15 × 100
=15%
The percentage discount =15% NOT 10% as you have written

Answer:
A.Step-by-step explanation:
Faktor (x-a) means a is x-intercept
x-10 ⇒ 10 is x-intercept
22-x ⇒ 22 is x-intercept
x+10 ⇒ -10 is x-intercept
20+x ⇒ -22 is x-intercept
so in the graph have to be at least two intercepts <0 and at least two intercepts >0
What is the equation of the line that passes through (–2, –3) and is perpendicular to 2x – 3y = 6?
Answer:
[tex]y=-\frac{3}{2}x-6[/tex]
Step-by-step explanation:
Since the line needs to be perpendicular to [tex]2x-3y=6[/tex], that means the slope of the line must be the opposite reciprocal. Rearrange the equation [tex]2x-3y=6[/tex] to solve for the value of y, with variable y on the left side.
[tex]-3y=-2x+6\\y=\frac{2}{3} x-2[/tex]
So, the slope of the line given already is [tex]\frac{2}{3}[/tex]. The opposite reciprocal of this is [tex]-\frac{3}{2}[/tex].
From what information we know so far (the slope) about the equation of the line we are trying to find, we can write a basic equation that allows us to solve for the y-intercept. Use the equation [tex]y=mx+b[/tex], where m is the slope (which we already found) and b is the y-intercept.
[tex]y=-\frac{3}{2}x+b[/tex]
Since we are given a set of coordinate points that the line must pass through, we can substitute (-2, -3) in for x and y in the equation above. Then, solve for the value of b, which is our y-intercept.
[tex]-3=-\frac{3}{2}(-2)+b\\ -3=3+b\\b=-6[/tex]
Now we have all the necessary information to create our equation.
[tex]y=-\frac{3}{2}x-6[/tex]

Which of the following possibilities will form a triangle?
Side = 13 cm, side = 6 cm, side = 6 cm Side = 13 cm, side = 5 cm, side = 8 cm Side = 14 cm, side = 7 cm, side = 6 cm Side = 14 cm, side = 6 cm, side = 9 cm
Wendy described four triangles as shown below:
Triangle A: All sides have length 9 cm. Triangle B: Two sides have length 10 cm, and the included angle measures 60°. Triangle C: Two angles measure 50°. Triangle D: Base has length 8 cm, and base angles measure 45°. Which triangle is not a unique triangle? Triangle A Triangle B Triangle C Triangle D
Victor wrote the following statement: "You can only draw one unique isosceles triangle that contains an angle of 85°." Which statement is true?
Victor is correct, because only one unique triangle can be drawn with the given information.
Victor is incorrect, because more than one triangle can be drawn with the given information.
Victor is incorrect, because the triangle described cannot be drawn with the given information.
None of the above.
Answer:
First question: last option
The triangle inequality states that the sum of he two shortest sides of a triangle must be greater than the longest side, therefore the answer is 14, 6, and 9 because 6 + 9 > 14 is a true statement.
Second question: I'm not sure, sorry
Third question: second option
He never specified if 85° was the base angle or not so he could draw 2 triangles: one with 85° as the base angles and one with 85° as the other angle.
Answer:
Step-by-step explanation:
first : Side = 13 cm, side = 6 cm, side =6
second : Side = 13 cm and 5 and 8
third: Side = 14 cm, side = 7 cm and 6
forth : 14 cm, side = 6 cm, side = 9 cm
to form a triangle the theory is: a+b>c and b+c>a and a+c>b
first one : a=13 b=6 and c=6 ( not a triangle)
second: a=13 b=5 and c=8 ( not a triangle)
third : a=14,b=7,c=6 (not a triangle)
forth : a=14,b=6,c=9 ( a triangle 14+6>9,6+9>14, and 9+14>6)
Wendy description :Triangle A: All sides have length 9 cm.
Triangle B: Two sides have length 10 cm, and the included angle measures 60°
Triangle C: Two angles measure 50°.
Triangle D: Base has length 8 cm, and base angles measure 45°
triangle A is equilateral triangle all sides are equal it is a special triangle because it has three sides and angles equal.
Triangle C: is not unique because you can not specify triangles by given angles only
Victor is incorrect, because more than one triangle can be drawn with the given information because only two sides are given and the third con be different.

A cylinder has a volume of 390 cm³. If a cone has the same dimensions as the cylinder then what is the volume of the cone.
Answer: The volume of the cone is 130 cubic centimeters.
Step-by-step explanation:
We know that to find the volume of a cylinder you will use the formula
V= [tex]\pi[/tex][tex]r^{2} *h[/tex] Where r is the radius and h is the height.
And to find the volume of a cone you will use the formula
V= [tex]\pi[/tex][tex]r^{2}[/tex]*h /3
So if they have the same dimensions which is the height and the radius then we will just divide the volume of the cylinder by 3 to find the volume of the cone.
V = 390/3
V = 130 cm^3

The two-way table shows the distribution of gender to favorite film genre for the senior class at Mt. Rose High School.
Which statement is true?
The probability of randomly selecting a student who has a favorite genre of drama and is also female is about 17 percent.
Event F for female and event D for drama are independent events.
The probability of randomly selecting a male student, given that his favorite genre is horror, is
16/40
.
Event M for male and event A for action are independent events.
Answer:
The second statement is correct
Step-by-step explanation:
Hello!
The table shows the information of the favorite film genre of the students of the class regarding their gender.
You have to prove which statement is correct:
1)The probability of randomly selecting a student who has a favorite genre of drama and is also female is about 17 percent.
If you chose a student at random, you need to calculate the probability of its favorite genre being "Drama" (D) and the student being female (F), symbolically: P(D∩F)
To do so you have to divide the number of observed students that are female and like drama by the total number of students:
P(D∩F)= [tex]\frac{24}{240}= \frac{1}{10} =0.10[/tex]
This means that the probability of choosing a student at random and it being a female that likes drama is 10%.
This statement is incorrect.
2) Event F for female and event D for drama are independent events.
Two events are independent when the occurrence of one of them doesn't affect the probability of occurrence of the other one.
So if F and D are independent then:
P(F)= P(F|D)
-or-
P(D)=P(D|F)
The probability of the event "Female" is equal to [tex]P(F)= \frac{Total females in the class}{n} = \frac{144}{240} = \frac{3}{5}= 0.6[/tex]
The probability of the event "Drama" is:
[tex]P(D)= \frac{Total students that like "Drama"}{n}= \frac{40}{240}= \frac{1}{6}= 0.166[/tex]
[tex]P(F|D)= \frac{P(FnD)}{P(D)}= \frac{\frac{1}{10} }{\frac{1}{6} }= \frac{3}{5} = 0.6[/tex]
As you can see P(F)= 0.6 and P(F|D)= 0.6 so both events are independent.
This statement is correct.
3) The probability of randomly selecting a male student, given that his favorite genre is horror, is 16/40
This is a conditional probability, you already know that the student likes horror movies (H), and out of that group you want to know the probability of the student being male (M):
[tex]P(M|H)= \frac{number of male students that like horror movies}{total students that like horror movies}= \frac{16}{38}= \frac{8}{19} = 0.42[/tex]
This statement is incorrect.
4) Event M for male and event A for action are independent events.
Same as the second statement, if the events "Male" and "Action" are independent then:
P(M)= P(M|A)
-or-
P(A)= P(A|M)
[tex]P(M)= \frac{96}{240}= \frac{2}{5}= 0.4[/tex]
[tex]P(A)= \frac{72}{240} =\frac{3}{10}= 0.3[/tex]
[tex]P(AnM)= \frac{28}{240}= \frac{7}{60}= 0.11666[/tex]
[tex]P(M|A)= \frac{P(MnA)}{P(A)}= \frac{\frac{7}{60} }{\frac{3}{10} } = \frac{7}{18}= 0.3888[/tex]
[tex]P(M)= \frac{2}{5}[/tex] and [tex]P(M|A)= \frac{7}{18}[/tex]
P(M)≠ P(M|A) the events are not independent.
This statement is incorrect.

Onyango is now three times as old as his daughter and four times as old as his son. Eight years from now, Onyango's age will be twelve years more than the sum of the ages of his son and daughter. Find their present ages.
Answer:
Onyango is 48, his daughter is 16 and his son is 12
Step-by-step explanation:
Let's call Onyango's age x, therefore his daughter and son's ages are 1/3 x and 1/4 x respectively. We can write:
x + 8 = 12 + (1/3x + 8 + 1/4x + 8)
x + 8 = 7/12x + 28
5/12x = 20
x = 48 → 1/3x = 48 / 3 = 16, 1/4x = 48 / 4 = 12

Write an equation expressing the volume of the box made by paper x by 16 from which a square with side length 2 is cut from each corner and the sides of a box will are folded as shown.
Answer: V = 24*(x - 4) with the condition x > 4.
Step-by-step explanation:
The volme of a cube/box is equal to:
V = W*L*H
where W = width, L = lenght and H = heigth.
First:
We know that the cubes cut in the corner have a side length of 2.
Then the remaining part is folded up, and this is now the height.
So the height of the box is equal to 2.
Now, we know that the initial measures of the piece of paper are x by 16
But now, in each extreme, we subtracted 2 units, that are now the new heiht, so now the piece of paper is (x -2 -2) by (16 -2 - 2)
or (x - 4) by 12.
Then the volume of the box is:
V = (x -4)*12*2 = 24*(x -4)
Notice something, if x is equal or smaller than 4, then we have a negative volume or a volume equal to zero. Those are problems in our model, so we should use the condition x > 4.

halla la medida del lado de un cuadrado cuya diagonal es de 14 cm
Answer:
7√2 cm
Step-by-step explanation:
Aquí, estamos interesados en encontrar la longitud del lado de un cuadrado que tiene una longitud diagonal de 14 cm.
Una diagonal es una línea que se extiende desde un borde del cuadrado hasta el otro borde del cuadrado internamente.
Ahora, una diagonal de un cuadrado junto con dos lados de un cuadrado forman un triángulo rectángulo isósceles, siendo la diagonal la hipotenusa de este triángulo rectángulo.
Sabemos que los lados de un cuadrado tienen la misma longitud y, por lo tanto, llamemos a este lado desconocido x cm.
Matemáticamente, según el teorema de Pitágoras, el cuadrado de la hipotenusa es igual a la suma de los cuadrados de los otros dos lados.
Por lo tanto, tenemos;
14 ^ 2 = x ^ 2 + x ^ 2
196 = 2x ^ 2
dividir ambos lados por 2
98 = x ^ 2 x = √98
x = √ (49 * 2)
x = 7√2 cm
Por lo tanto, la longitud del lado del cuadrado es de 7√2 cm

Answer:
$10 balcony
$15 orchestra
Step-by-step explanation:
We can solve for the prices of each seat by creating an algebraic expression:
Let 'x' be the cost of a balcony seat:
and 'x + 5' be the cost of an orchestra seat.
200 of both seats were sold, therefore:
200(x) + 200(x + 5) = 5000
Distribute:
200x + 200x + 1000 = 5000
Combine like terms:
400x + 1000 = 5000
Subtract 1000 from both sides:
400x = 4000
Divide:
x = $10 for the balcony seat.
Substitute this value of x to solve for the cost of an orchestra seat:
(10) + 5 = $15.
Therefore:
$10 balcony
$15 orchestra
Do,2 of Y is:
(5, 4)
(6,4)
(3/2,1)
Answer:
(6,4)
Step-by-step explanation:
This question asks you to dilate by a factor of 2, and from the origin. Because it is from the origin, we can simply multiply the coordinates of Y by 2
3*2=6
2*2=4
so the result is 6,4
The dilation of the coordinate Y(3, 2) by 2 is (6, 4). we just have to multiply the y coordinate by 2.
What is dilation?Dilation simply means changing the size of an object without changing its shape.
In other words dilation is a transformation that reudces or enlarges a particular shape.
Therefore, we are asked to dilate the coordinate of y by 2.
Hence, we have to multiply the coordinates of y by 2 to get the new dilated figure.
Dilation of Y by 2 is 2(3, 2) = (6, 4)

A contractor can spend at most $250 a day on operating costs and payroll. It costs $45 each day to operate the forklift and $60 a day for each crew member. Write an inequality to represent the contractor's budget for the day.
Answer: [tex]45+65x\leq250[/tex] .
Step-by-step explanation:
Given: Cost to operate the forklift per day = $45
Cost for each crew member per day = $65
Let x be the number of crew members.
Then, we have
Total cost = (Cost to operate the forklift per day)+(Cost for each crew member per day)×(number of crew members)
= 45+65x
Since, the contractor can spend at most $250.
Then, the required inequality: [tex]45+65x\leq250[/tex] .

Answer:
D: It has reflectional symmetry with one line of symmetry
Step-by-step explanation:
The reason D is the answer is because, the tree has the same sides and if you put a line in the middle of the tree it is identical to the other side.
The image has a reflectional symmetry with one line of symmetry. The correct option is d.
A reflectional symmetric image has at least one line (axis) along which it can be folded or reflected to produce a complementary or identical image on the opposite side. The image is split along this line of symmetry into two equal halves that are mirror images of one another. The reflectional symmetry gives the picture a feeling of harmony and balance.
It is similar to viewing an image through a mirror in that the portion that is reflected is an exact replica of the original. This kind of symmetry is frequently found in many patterns and objects in nature, art and architecture which enhances the overall design's aesthetic appeal and visual interest.

Price elasticity of demand for tomatoes is 1.30. If hail storm adversely affects the nation’s production of tomatoes what will be the impact on total revenue from tomatoes and why?
Answer:
The total revenue will decrease.
Step-by-step explanation:
The price elasticity of demand is 1.30 that shows that change in the quantity of tomatoes is greater than the change in the price of tomatoes. The hail storm will decrease the quantity (supply) of tomatoes. However, this decrease in supply will increase the price but the ratio of change in quantity will be more than the ratio of change in price. Thus, total revenue from tomatoes will also fall.
