what is the answer to
0.75x-0.5=x+1.5
Answer:
The result for the equation is [tex]x = -8[/tex] .
Step-by-step explanation:
-Solve the equation:
[tex]0.75x -0.5 =x +1.5[/tex]
-Subtract [tex]x[/tex] from [tex]0.75x[/tex] :
[tex]0.75x -0.5-x =x -x+1.5[/tex]
[tex]-0.25x -0.5 = 1.5[/tex]
-Add both sides by 0.5 :
[tex]-0.25x -0.5 +0.5 =1.5 +0.5[/tex]
[tex]-0.25x = 2[/tex]
-Divide both sides by 0.25 :
[tex]\frac{-0.25x}{-0.25} =\frac{2}{-0.25}[/tex]
[tex]x = -8[/tex]
So, the answer for the equation is [tex]x = -8[/tex] .

-1/2y=1/2x+5 and y=2x+2
I assume this is the intersection of two lines, i.e. -1/2y is (-1/2)y. Please tell me if it's really -1/(2y).
(-1/2)y=(1/2)x+5
Multiplying both sides by -2
y = - x - 10
The other equation is
y = 2x + 2
We can equate them to find the meet
y = - x - 10 = 2x + 2
-3x = 12
x = -4
y = 2x + 2 = -6
Check: (-1/2)y=3, (1/2)x+5=3, equal, good
2x+2=2(-4)+2=-6=y, good
Answer: x=-4, y=-6

in a class of 26 student, 15 of them like maths, 13 of them like english and 9 of them don't like maths or english.
Find the probability that a student chosen at random like english but not maths.
Answer:
2/26
Step-by-step explanation:
The total number of students = 26 students
Number of students that like maths = 15 students
Number of students that like English = 13 students
Number of students that does not like English or maths = 9
We have to find the number of students that likes both Maths and English.
Therefore,
Let x be the number of student that like both Maths and English subjects
15 - x + x + 13 - x + 9 = 26
-x + 37 = 26
-x = -11
x = 11
Number of student that offer english but not math
Number of students that like English but not Maths = Number of Students that like English - Number of students that like English and Maths
= 13 - 11 = 2
Therefore, probability that a student chosen at random like English but not Maths.
Probability = Number of events ÷ Number of possible outcomes
Number of events = Number of students that like English but not Maths= 2
Number of Possible outcomes = Total number of students = 26
The probability that a student chosen at random like English but not Maths.
= 2/26

What is 65,321 rounded to the nearest ten thousand?
Answer:
70,000
Step-by-step explanation:
5 always rounds UP to the nearest whole number, therefore, 70,000.
65321 rounded to nearest ten thousand's place becomes 70000.
How to round a number to ten thousands place ?An easy way of rounding numbers to ten thousand's place we'll understand by an example.
65321 have to rounded to ten thousand's place which is either 60000 or 70000.Here the given number is more closer to 70000 than 60000 so therefore 65321 rounded to the nearest ten thousand is 70000.
According to the given question
We have 65321 and we have to round it to the nearest ten thousand.
To round a number nearest to ten thousand first we'll check the digit of thousand's place which is 5 we'll add 1 to it make all the digits after that 0.
Now this becomes 66000.
Now we'll check for the digit in ten thousand's place which is 6 we'll add 1 to it and make the rest of the digits 0 hence it becomes 70000.

The number of computers a certain computer store sold since 2005 can be modeled by the function N(t)=5t+106 and the price per computer can be modeled by P(t)=13t^2-25t plus 600, where t is the number of years since 2005. According to this model, what is the total amount of revenue generated by the computer store's sales in 2010? Round your answer the nearest cent.
Answer:
104800
Step-by-step explanation:
The revenue is the profit times the number of computers sold
R(t) = P(t) * N(t)
= (13t^2-25t+600) * ( 5t+106)
We want the revenue in 2010 which is 5 years from 2005 so t = 5
R(5) = (13* 5^2-25*5+600) * ( 5*5+106)
= (13 *25 - 125+600)*(25+106)
= (325-125+600) * ( 25+106)
(325-125+600) * ( 25+106)
800* 131
104800
Answer:
104,800
Step-by-step explanation:
2010 is 5 years after 2005, so t = 5
The number of computers sold:
N(5)=5(5)+106 = 131
Price per computer:
P(t)=13(5²)-25(5)+600 = 800
Revenue:
N × P
131 × 800

Find the lateral area and surface area of a regular hexagonal right prism is the base edges are 10 and the height is 12.
Round your answer to the nearest tenth.
LA = units squared
SA = units squared
Answer:
Step-by-step explanation:
a hexagonal prism is made up of two bases that are hexagons and six faces that are rectangles.
Lateral surface area, LA = Perimeter × height
Perimeter = number of sides × length of each side
Perimeter, P = 6 × 10 = 60
LA = 60 × 12 = 720 units squared
Area of each base, B = 1/2a × perimeter
Where
a = apotherm
We would determine the length of the apotherm of each base of the prism by applying the formula,
a = s/[2tan(180/n)]
Where
s = length of each side = 10
n = 6 sides
a = 10/[2tan(180/6) = 10/[2tan30)
a = 8.66
B = 1/2 × 8.66 × 60 = 259.8
Total surface area = LA + 2B
Total surface area = 720 + 2 × 259.8 = 1239.6 units squared

Answer:
The area of Polygon

WW is

4949 square units.
Step-by-step explanation: dk
Scale factors are used to enlarge or reduce the size of a shape
The area of polygon w is 49 square units
The area of polygon v is given as:
[tex]v =1[/tex]
The scale factor of the sides of polygon v, that forms polygon w is given as:
[tex]k=7[/tex]
The area of polygon w is then calculated as:
[tex]w =v\times k^2[/tex]
So, we have:
[tex]w =1\times 7^2[/tex]

Faron wants to paint the four walls in his bedroom. The room measures 12 ft long, 10 ft wide and 8 ft high. There are two doors that each measure 3 ft by 7 ft and a window that measures 3 ft by 4 ft. If Faron does not paint the doors and window, what is the total area he will paint?
Answer:
319 square feet.
Step-by-step explanation:
The walls of the room (the ones on the long side) have an area of 12 x 8 = 96 square feet each one. Thus, their area is 96 x 2= 192 square feet.
The other two walls have an area of 10 x 8 = 80 square feet each one. Thus, their area combined is 80 x 2 = 160 square feet.
Therefore, we have that the total area of the four walls is
192 +160 = 352 square feet
However, we have a door and a window that won't be painted.
The area of the door is: 3 x 7 =21 square feet
The area of the window is 3 x 4 = 12 square feet
Thus, the total amount of area that won't be painted is
21 + 12 = 33 square feet.
So we are going to take the total area minus the area that won't be painted to know the total area that Faron will pain:
352 - 33 = 319 square feet.
Thus, she will paint 319 square feet
Use the Trapezoidal Rule with n = 4 to approximate
0.3523
0.7048
0.2456
0.4913
Answer:
0.7048
Step-by-step explanation:
∫₂⁴ 1 / (x − 1)² dx
n = 4, so we divide the interval into 4 regions. The width of the regions is:
(4 − 2) / 4 = 0.5
So the intervals are (2, 2.5), (2.5, 3), (3, 3.5) and (3.5, 4).
Evaluate f(x) at the ends of each interval.
f(2) = 1
f(2.5) = 4/9
f(3) = 1/4
f(3.5) = 4/25
f(4) = 1/9
Find the area of each trapezoid:
A₁ = ½ (2.5 − 2) (1 + 4/9) = 13/36
A₂ = ½ (3 − 2.5) (4/9 + 1/4) = 25/144
A₃ = ½ (3.5 − 3) (1/4 + 4/25) = 41/400
A₄ = ½ (4 − 3.5) (4/25 + 1/9) = 61/900
So the total approximate area is:
A = 0.705
Closest answer is 0.7048.
The value of expression is,
⇒ 0.7048
What is an expression?Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.
Given that;
⇒ ∫₂⁴ 1 / (x − 1)² dx
Now, For n = 4, we divide the interval into 4 regions.
Hence, The width of the regions is:
= (4 − 2) / 4
= 0.5
Thus, the intervals are,
⇒ (2, 2.5), (2.5, 3), (3, 3.5) and (3.5, 4).
Thus, We can evaluate f(x) at the ends of each interval as,
f(2) = 1
f(2.5) = 4/9
f(3) = 1/4
f(3.5) = 4/25
f(4) = 1/9
Hence, the area of each trapezoid are,
A₁ = 1/2 (2.5 − 2) (1 + 4/9) = 13/36
A₂ = 1/2 (3 − 2.5) (4/9 + 1/4) = 25/144
A₃ = 1/2 (3.5 − 3) (1/4 + 4/25) = 41/400
A₄ = 1/2 (4 − 3.5) (4/25 + 1/9) = 61/900
Therefore, the total approximate area is:
A = A₁ + A₂ + A₃ + A₄
A = 0.7048

The mean life of a Brand Q car battery is 36 months. The standard deviation is 4 months.
68% of all batteries will have a life between _____ months and _____ months.
95% of all batteries will have a life between _____ months and _____ months.
Answer:
Step-by-step explanation:
Let x be a random variable representing the life of a Brand Q car battery. With the mean and standard deviation given, then the Empirical Rule says the that
1) About 68% of the x values lie between 1 standard deviation below and above the mean.
2) About 95% of the x values lie between 2 standard deviations below and above the mean.
3) About 99.7% of the x values lie between 3 standard deviations below and above the mean.
From the information given,
mean = 36 months
Standard deviation = 4 months
Therefore,
1) 68% of all batteries will have a life between 36 - 4 = 32 months and 36 + 4 = 40 months.
2) 95% of all batteries will have a life between 36 - 2(4) = 28 months and 36 + 2(4) = 44 months.
