8/y = 2/y-2 +1 Answer fast please.
Answer:
Given equation is (8/y) = 2/(y-2) +1
=> (8/y)- 2/(y-2) = 1
=> [8(y-2)-2y]/(y-2)y = 1
=> (8y-16-2y)/(y²-2y) = 1
=> (6y-16)/(y²-2y) = 1
=> y²-2y = 6y-16
=> y²-2y -6y+16 = 0
=> y²-8y+16 = 0
The standard form is y²-8y+16 = 0.
Answer:
-6
Step-by-step explanation:
8/y = 2/y - 2 + 1
8/y = 2/y - 1
8 = 2 - y
6 = -y
y = -6

Answer:
.98 L / b * .4 b = .392 L amount contained in sample
.99 L / b * .25 b = .248 L this was rounded from .2475
1.00 L / b * .3 b = .30 L
1.01 L / b * .05 b = .05 L
---------------------------------------
3.98 L / 4 b * 1.0 b = .99 L
Actual measurements might be 40 bottles at .98 L/b, 25 bottles at .99 etc
Then the total liters would be divided by the total number of bottles

The sum of four consecutive odd numbers is 80 find the number
Answer:
Let the numbers are
x, (x+2), (x-2) and (x+4)
Step-by-step explanation:
x + x +2 +x - 2+x+4 = 80
4x +4 = 80
4x =80-44x = 76
4x = 76
x = 76/4
x = 19x
x=19
(x+2) =19+2=21
(x-2) = 19-2=17
(x+4)=(19+4)=23

The perimeter, p, of an equilateral triangle varies directly as the length of a side, s, if
the perimeter is 153 cm when the side length is 51 cm, what would be the perimeter if
the side length is 81 cm.
Variation can be direct, inverse or joint.
The perimeter is 243 cm
Represent perimeter with P and side lengths with L.
So, we have:
[tex]\mathbf{P\ \alpha\ L}[/tex]
Express as an equation
[tex]\mathbf{P = kL}[/tex]
Where k is the constant of variation.
Make k the subject
[tex]\mathbf{k = \frac PL}[/tex]
So, we have:
[tex]\mathbf{\frac{P_1}{L_1} = \frac{P_2}{L_2}}[/tex]
Make P2 the subject
[tex]\mathbf{P_2 = L_2 \times \frac{P_1}{L_1} }[/tex]
Substitute the given parameters
[tex]\mathbf{P_2 = 81 \times \frac{153}{51} }[/tex]
[tex]\mathbf{P_2 = 81 \times 3 }[/tex]
[tex]\mathbf{P_2 = 243}[/tex]
Hence, the perimeter is 243 cm

A restaurant sells tea for
$1.50 per drink. The cost of drinks, F(d), can be found by using the function F(d) = 1.5d. If the restaurant sells no more
than $150 in drinks in a day, what is a reasonable domain and range
Thank you!
Domain:
Range:
Answers:
Domain is [tex]0 \le d \le 100[/tex]
Range is [tex]0 \le F(d) \le 150[/tex]
==============================================
Explanation:
The most money made from selling drinks is $150. Divide this over the cost per drink to get 150/(1.50) = 100; indicating that at most 100 drinks are sold per day. This is the largest that d can get because d represents the number of drinks sold.
The smallest d can get is d = 0 to mean that no drinks are sold.
In short: d is between 0 and 100, including both endpoints. We write [tex]0 \le d \le 100[/tex] to indicate this. This is the domain because the domain represents all the possible inputs allowed.
---------------------------------------------------
The range is the set of allowed outputs.
If we plugged in d = 0, then you would find F(d) = 0 as well. If you don't sell any drinks, then you earn $0. This is the smallest item in the range.
On the other side of things, the largest item in the range is 150 because this value was given to us. It's the upper limit or ceiling value of how much money is made from drinks. You can also find this by plugging d = 100, the largest domain value, into the function to get F(d) = 150.
Therefore the range is [tex]0 \le F(d) \le 150[/tex] to indicate that F(d) is between 0 and 150 inclusive of both endpoints.

Kishore bought a basket containing 30 orangs for rs 310. If he sells the orangs at rs 12 each , what Would be it's profit or loss?
Given : Kishore bought a basket containing 30 oranges for rs 310. If he sells the oranges at rs 12 each , what Would be it's profit or loss?
Solution :
Cost price of oranges = rs.310
As we know that each oranges cost rs.12
So, selling price of oranges is 30 × 12 = rs.360
Now, finding profit or loss
Profit = Selling Price - Cost Price
Profit = rs.360 - rs.310
Profit = rs.50
So, the profit is ₹50how do i change the fraction into a decimal?
3/4 as a decimal?
Answer:
0.75
Step-by-step explanation:
1. To change 3/4 into a decimal, you have to divide 3 by 4.
2. (Check out the image below to see how to divide 3 by 4.)
Answer:
3/4 is expressed as 0.75 in the decimal form.
Step-by-step explanation:
Fractions and decimals are two ways to represent the same numbers. A decimal number can be defined as a number whose whole number part and fractional part is separated by a decimal point. A fraction is represented as a numerical value that is defined as a part of a whole.
To convert any fraction to decimal form, we just need to divide the numerator by the denominator.
Here the fraction is 3/4 which means we need to divide: 3 ÷ 4.
* Use the attatched images for steps*
Therefore, 3/4 = 0.75.
Thus, 3/4 is expressed as 0.75 in the decimal form.

Answer:
1/7 km long
Step-by-step explanation:
The area of a square is any given one of the sides, squared. We can take this information and apply it to this problem. If the area is 1/49 km squared, we can take the square root of this to find the length of each side.
The square root of 1 is 1, and the square root of 49 is 7, so the answer is 1/7 km for each side.

The corresponding roots of the quadratic equations are given.
What are Quadratic Equations?Quadratic expressions are polynomial equations of second degree.
The general form of a quadratic equation is ax² + b x + c = 0.
1. x² = 49
Find the square root.
x = ±√49 = ±7
2. x² - 27 = 0
x² = 27 = 9 × 3
x = √27 = √(9×3) = √9 × √3 = ±3√3
3. 3x² - 36 = 0
3x² = 36
Divide 3 on both sides.
x² = 12
x = √12 = √(4 × 3) = ±2√3
4. 9x² = 0
x = 0
5. 5x² - 15 = 0
5x² = 15
x² = 3
x = ±√3
6. 2x² - 144 = 0
2x² = 144
x² = 72
x = √72 = √(36 × 2) = ±6√2
7. (x + 3)² = 9
x + 3 = √9
x + 3 = ±3
x = 3 - 3 = 0 and x = -3 - 3 = -6
8. 4x² - 100 = 0
4x² = 100
x² = 25
x = ±√5
9. 5x² = 40
x² = 8
x = √8 = √(4 × 2) = ±2√2
10. 3x² - 12 = 0
3x² = 12
x² = 4
x = ±2
11. (x - 5)² = 121
x - 5 = √121
x - 5 = ±11
x = 11 + 5 = 16 or x = -11 + 5 = -6
Hence the solutions are found.

range is top to bottom, there is no bottom bc of the arrow, but it has a top at 2 (the value on the y axis)
the axis of sym is basically the line that runs through the vertex, it's where you could fold it in half and it would still match up
