Use the equation Y = {/27x-54 +5.
Which is an equivalent equation of the form
y=avx-h+k
y=-273x + 2+5
y=-3x+2 +5
y=34x-2 +5
y=273/x-2 +5
Answer:
y= 34x- 2 +5 (C)
Step-by-step explanation:
The equation: y = 27x-54 +5
We are to determine an equivalent equation of the form y=avx -h+k from the options given.
From the above, av = two digit coefficient of x. Hence av is constant.
h and k are also constant.
Let's check out the option to find the equation that is in the form y=avx-h+k
a) y=-273x + 2+5
In this equation, the coefficient of x is a 3-digit number. The option is wrong.
b) y=-3x+2 +5
In this equation, the coefficient of x is a 1-digit number. The option is wrong.
c) y=34x -2 +5
In this equation, the coefficient of x is a 2-digit number.
av = 34, h= 2 and k = 5
This equation is in the form of y=avx -h+k
The option is correct.
d) y=273/x-2 +5
This equation is not in the form of y=avx -h+k
The option is wrong.

This figure is made up of a triangle and a semicircle. What is the area of this figure? Use 3.14 for pi. Round only your final answer to the nearest tenth. Enter your answer, as a decimal, in the box
Answer:
Area = 14.8 units²
Step-by-step explanation:
Base of Triangle = 2 units
Height of Triangle = 5 units
Radius of the semi circle = 2.5 units
Now,
Triangle:
Area of triangle = 1/2(base*height)
Area = 1/2(2*5)
Area = 1/2(10)
Area = 5 units²
Semi-Circle:
Area of semi-circle = 1/2(πr²)
Area = 1/2(3.14)(2.5)²
Area = 1/2(3.14)(6.25)
Area = 9.8 units²
Area of the figure:
Area = 5 + 9.8
Area = 14.8 units²

Find the area of a rectangle with base 4 ft and height 4 in. (Note: 1 ft = 12 in.) 192 in2 88 in2 16 in2 104 in2
Answer: 192 in²
Step-by-step explanation:
The area of a rectangle is to multiply the length and the width, or the base and height. Since we are given the base and the height, we can multiply them to find the area. Since the units are different between the height and base, we need to make sure to have the height be 48 in.
A=4×48=192 in²

A rancher has 4,200 feet of fencing available to enclose a rectangular area bordering a river. He wants to separate his cows and horses by dividing the enclosure into two equal areas. If no fencing is required along the river, find the length of the center partition that will yield the maximum area.
Answer:
The center portion's length will be "700 ft".
Step-by-step explanation:
Let the center will be "x".
Given that, Length = 4200 feet
Now, Length
⇒ [tex]L=3x+y[/tex]
⇒ [tex]4200=3x+y[/tex]
⇒ [tex]y=4200-3x[/tex]
As we know,
Area,
⇒ [tex]A=Length\times breadth=x\times y[/tex]
⇒ [tex]=x(4200-3x)[/tex]
⇒ [tex]=4200x-3x^2[/tex]
So that the length or center portion or the area will be greater or maximum when:
⇒ [tex]x=-\frac{4200}{2\times (-3)}[/tex]
⇒ [tex]=\frac{-4200}{-6}[/tex]
⇒ [tex]=700 \ ft[/tex]
What is the final rate cost of a item that is $40 after 8% tax applied
Answer:
$43.20
Step-by-step explanation:
First, find the tax.
Multiply the tax rate by the cost of the item.
tax rate * item cost
The tax rate is 8% and the item costs $40
8% * 40
Convert 8% to a decimal. Divide 8 by 100 or move the decimal 2 places to the left.
8/100=0.08
8.0–> 0.8–> 0.08
0.08*40
Multiply
3.2
The tax is $3.20
Now, add the tax on to the cost of the item.
cost of item + tax
The item costs $40 and the tax is $3.20.
$40 + $3.20
Add
$43.20
The cost of the item after tax is $43.20
Answer:
$43.2
Step-by-step explanation:
given;
the price of an item=$40
tax rate =8%
now ,final rate= price of an item+ 8%of price of an item.
so, finalrate= $40+ 8% of $40
=$40+8/100×$40

Answer:
(3, - 9)
Step-by-step explanation:
Differentiate using the power rule
y = a[tex]x^{n}[/tex] , then
[tex]\frac{dy}{dx}[/tex] = na[tex]x^{n-1}[/tex]
Given
y = x² - 6x
[tex]\frac{dy}{dx}[/tex] = 2x - 6
Equate to zero since the measure of gradient is [tex]\frac{dy}{dx}[/tex] , that is
2x - 6 = 0 ( add 6 to both sides )
2x = 6 ( divide both sides by 2 )
x = 3
Substitute x = 3 into y for corresponding value of y
y = 3² - 6(3) = 9 - 18 = - 9, thus
(3, - 9 ) are the coordinates of the point where the gradient is zero

[tex]\to 10=a(10)^2\\\\\to 10=100a\\\\\to a=\frac{10}{100}\\\\\to a= \frac{1}{10}\\[/tex]
if the value of a= [tex]\frac{1}{10}[/tex] then put the value into the equation:
[tex]\to y=\frac{x^2}{10}\\\\[/tex]
when depth of water y=5
[tex]\to 5=\frac{x^2}{10}\\\\\to x^2=50\\\\\to x=\pm\sqrt{50}\\\\[/tex]
So, width:
[tex]\to 2\sqrt{50}=2\sqrt{25 \times 2}\\[/tex]

1. Miguel is playing a game in which a box contains four chips with numbers written on them. Two of the chips have the number 1, one chip has the number 3, and the other chip has the number 5. Miguel must choose two chips, and if both chips have the same number, he wins $2. If the two chips he chooses have different numbers, he loses $1 (–$1). a. Let X = the amount of money Miguel will receive or owe. Fill out the missing values in the table. (Hint: The total possible outcomes are six because there are four chips and you are choosing two of them.) b. What is Miguel’s expected value from playing the game? c. Based on the expected value in the previous step, how much money should Miguel expect to win or lose each time he plays? d. What value should be assigned to choosing two chips with the number 1 to make the game fair? Explain your answer using a complete sentence and/or an equation.
Answer:
To check all the events (6), we label the chips. Suppose one chip with 1 is labeled R1 and the other B1 (as if they were red and blue). Now, lets take all combinations; for the first chip, we have 4 choices and for the 2nd chip we have 3 remaining choices. Thus there are 12 combinations. Since we dont care about the order, there are only 6 combinations since for example R1, 3 is the same as 3, R1 for us.
The combinations are: (R1, B1), (R1, 3), (R1, 5), (B1, 3), (B1, 5), (3,5)
We have that in 1 out of the 6 events, Miguel wins 2$ and in five out of the 6 events, he loses one. The expected value of this bet is: 1/6*2+5/6*(-1)=-3/6=-0.5$. In general, the expected value of the bet is the sum of taking the probabilities of the outcome multiplied by the outcome; here, there is a 1/6 probability of getting the same 2 chips and so on. On average, Miguel loses half a dollar every time he plays.

The longitude of Allahabad, India is 81° 50' (81 degrees, 50 minutes) E. If the time in Allahabad is around 12 noon, what time of the day would it be, at a place whose longitude is 10°W?
Answer:
ok
Step-by-step explanation:
this is what you answered me for my question
Answer:
6 AM
Step-by-step explanation:
The difference:
81°50' - (10° W) = 81°50' - (-10°)= 91° 50'
As we know each 15° represents 1 hr difference
91° 50' ÷ 15°= 6 in full number, so 6 hours difference
Since new point is towards West, the time difference would be negative:
12 PM - 6 hours = 6 AM
If a translation of (x, y) = (x + 6. y-10) is applied to figure

0 (-5.-2)
O (1.-12)
O (4, -15)
0 (-9,-6)
Answer:
The answer is "(1, -12)"
Step-by-step explanation:
In the given question some information is missing, that is the attachment of the graph, which can be attached as follows:
In the attached figure file, the quadrilateral ABCD vertices are (-3, 4), (3,4),(1,-2), and (-5,-2)
To find the coordinates of the D' the translation of (x, y) = (x + 6, y-10)
where point D=(-5, -2),
[tex]\to x=x+6\ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \to y=y-10\\\\\to x=-5+6 \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \to y=-2-10 \\\\\to x=1 \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \to y=-12[/tex]
So, the coordinates of D' is (1,-12).

The system that represents his scores is below. x – y = 16 StartFraction 1 over 8 EndFraction x plus StartFraction one-half EndFraction y equals 52.x + StartFraction one-half EndFraction x plus StartFraction one-half EndFraction y equals 18.y = 52 What is the higher grade of Jose’s two tests?
Answer : 96
x – y = 16 --------> equation 1
1/8 x + 1/2 y = 52
x is the higher grade and y is the lower grade
We solve the first equation for y
x - y = 16
-y = 16 -x ( divide each term by -1)
y = -16 + x
Now substitute y in second equation
1/8 x + 1/2 ( -16 + x ) = 52
1/8x - 8 + 1/2 x = 52
1/8x + 1/2x - 8 = 52
Take common denominator to combine fractions
1/8x + 4/8x -8 = 52
5/8x - 8 = 52
Add 8 on both sides
5/8x = 60
Multiply both sides by 8/5
x = 96
We know x is the higher grade
96 is the higher grade of Jose’s two tests.
The higher grade and lower grade of Jose’s two tests will be 96 and 80.
What is the solution of the equation?The solution of the equation means the value of the unknown or variable.
Jose asks his friends to guess the higher of two grades he received on his math tests.
He gives them two hints.
Let x be the higher number and y be the lower number.
The difference of the two grades is 16.
x - y = 16 ...1
The sum of one-eighth of the higher grade and one-half of the lower grade is 52.
x/8 + y/2 = 52
x + 4y = 416 ...2
Subtract equation 1 from 2, we have
4y + y = 416 – 16
5y = 400
y = 80
Then the value of x will be
x – 80 = 16
x = 80 + 16
x = 96
The higher grade and lower grade of Jose’s two tests will be 96 and 80.
