Jessica is building a fence around her garden. For every 3 feet of fencing, the cost is $27. Complete the table below showing the length of the fence and the cost.
Answer:
1, 54, 9, 90
Step-by-step explanation:
3ft=27$, so 1ft=9$. The constant of proportionality is 9 from feet to money so multiply the rest by 9 to get 54, divide backwards to get 9, and then multiply 10 by 9 to get 90.
Answer:
Length : 6 9 10
Cost ($) :54 81 90
Step-by-step explanation:
First, divide 27 by 3 to find the cost of 1 feet fence.
We get the answer 9
Then, to find the length, divide the cost by 9
And to find the cost, multiply the length of fence with 9.

What is the Pythagorean theorem?Pythagorean theorem states that in the right angle triangle the hypotenuse square is equal to the square of the sum of the other two sides. According to this statement, the areas of the squares on the other two sides add up to the size of the square whose side is the hypotenuse.
Apply the Pythagorean theorem for the first triangle,
H² = x² - 6²
Apply the Pythagorean theorem for the second triangle,
B² = 27² - x²
Apply the Pythagorean theorem to the third triangle,
H² = 27² - x² - 21²
H² = -x² + 288
x² - 6² = -x² + 288
2x² = 424

Rationalise the denominator 1/5-root 2
Answer:
the rationalized form of the denominator 1/(5^(1/2)-2) is (x+2)/((x-2)(x-1)(x+1)).
Step-by-step explanation:
Correctly me if im wrong. To rationalize the denominator of the fraction 1/(5^(1/2)-2), we can use the conjugate of the denominator. The conjugate of a+b is a-b, so the conjugate of 5^(1/2)-2 is 5^(1/2)+2. We can then multiply the numerator and denominator of the fraction by the conjugate to obtain:
1/(5^(1/2)-2) * (5^(1/2)+2)/(5^(1/2)+2)
= (1*(5^(1/2)+2)) / ((5^(1/2)-2)*(5^(1/2)+2))
= (5^(1/2)+2) / (5^2 - 2*5^(1/2) - 4)
Notice that we can further simplify this expression by substituting 5^(1/2) with x and expanding the denominator:
(5^(1/2)+2) / (5^2 - 2*5^(1/2) - 4)
= (x+2) / (x^2 - 2x - 4)
= (x+2) / (x-2)(x+2)
The denominator of this expression can be further simplified by factoring out x-2, which gives us:
(x+2) / (x-2)(x+2)
= (x+2) / (x-2)(x-2 + 4)
= (x+2) / (x-2)(x^2 - 2x + 4 - 4)
= (x+2) / (x-2)(x^2 - 2x)
= (x+2) / (x-2)((x-1)(x+1))
Finally, we can use the fact that x-1 and x+1 are factors of x^2-2x, which means that we can factor out x-1 and x+1 from the denominator to obtain the fully simplified expression:
(x+2) / (x-2)(x^2 - 2x)
= (x+2) / (x-2)(x-1)(x+1)
= (x+2) / ((x-2)(x-1)(x+1))
Therefore, the rationalized form of the denominator 1/(5^(1/2)-2) is (x+2)/((x-2)(x-1)(x+1)).
An airplane can level 1,500 miles in 4.5 hours at a constant speed how long will it take the airplane to travel 200 miles
Answer: 0.6 hours
Step-by-step explanation:
We will set up a proportion to help us solve.
[tex]\displaystyle \frac{1,500\; \;miles}{4.5\;\;hours} =\frac{200\;\;miles}{x\;\;hours}[/tex]
Next, we will cross-multiply and solve by multiplying and using inverse operations.
1,500 * x = 200 * 4.5
1,500x = 900

Two stores have the same item for the same price. • Store A offers successive discounts of 5% one week, 10% the next week, and 10% the third week. • Store B offers one discount of 25% the third week. Which offer results in the greater discount? Justify your answer. Show your work.
Answer:
Below
Step-by-step explanation:
10 % OFF means you pay 90% of price
x = original price
Store A : 5% off means price is .95x
then another 10% off would mean .9 * (.95x)
then another 10% off would mean .9 * ( .9 *(.95x)
this equals .7695 x
Store B 25% off means you pay 75%
price is then .75x
price of .75x at store B is < than .7695 x at store A
so B has greater discount
Answer:
Step-by-step explanation: To compare the discounts offered by Store A and Store B, we need to calculate the final price of the item after all discounts have been applied.
For Store A, the successive discounts of 5%, 10%, and 10% can be applied as follows:
The initial price of the item is reduced by 5%, resulting in a price of 0.95 * Price.
The price from step 1 is reduced by an additional 10%, resulting in a price of 0.9 * (0.95 * Price) = 0.855 * Price.
The price from step 2 is reduced by an additional 10%, resulting in a price of 0.9 * (0.855 * Price) = 0.7695 * Price.
For Store B, the single discount of 25% can be applied as follows:
The initial price of the item is reduced by 25%, resulting in a price of 0.75 * Price.
Comparing the final prices of the item at Store A and Store B, we can see that Store B offers a greater discount. The final price of the item at Store A is 0.7695 * Price, while the final price at Store B is 0.75 * Price. Since 0.75 is less than 0.7695, the final price at Store B is lower.
Therefore, Store B offers a greater discount on the item.
The coordinates of points a and b are a(2, 16) and b(22, 4). what are the coordinates of the point that is 34 of the way from a to b?
The coordinates of the point is (17, 7)
How to determine the coordinates of the point?From the question, we have the following parameters that can be used in our computation:
Point A = (2, 16)
Point B = (22, 4)
Ratio = 3/4
The ratio can be expressed as
m : n = 3 : 1
The coordinates of the point can be calculated as
Point = 1/(m + n) * (mx2 + nx1, my2 + ny1)
Substitute the known values in the above equation, so, we have the following representation
Point = 1/(3 + 1) * (3 * 22 + 1 * 2, 3 * 4 + 1 * 16)
So, we have
Point = 1/4* (68, 28)
So, we have
Point = (17, 7)

y₁ = y-coordinate of point one
m = slope
x = x-coordinate of second point

On simplifying the equation , we get
2.5p + 1.5h = 30 be equation (1)
Multiply equation (1) by 10 , we get
25p + 15h = 300
Now , the values of p and h which will satisfy the equation is
a)
Let p = 0 , h = 20
The equation is 25p + 15h = 300
Substitute the value of p and h , we get

Answer: The differential equations is

Step-by-step explanation:
break the given original- value problem. The DE is homogeneous. xy2dy/ dx = y3- x3; y( 1) = 2.
result
Given a homogenous discriminational equation, xy2 dy/ dx = y3- x3
xy2dy/ dx = y3- x3
dy/ dx = ( y3- x3)/ xy2
dy/ dx = (( y/ x) 3- 1)/( y2/ x2)---( 1)
Put y/ x = v ⇒ y = xv
separatew.r.t x
dy/ dx = x.dv/ dx v
Equation( 1) becomes,
⇒ dv/ dx v = ( v3- 1)/ v2
⇒ dv/ dx = (( v3- 1)/ v2)- v
⇒ dv/ dx = ( v3- 1- v3)/ v2
v2. dv = -1/x.dx
Integrate on both sides, we get
∫ v2. dv = ∫- 1/x.dx
v3/ 3 = - logx C
1/3( y3/ x3)) log x = C( 2)
Now, given that y( 1) = 2
Substituting y = 2 and x = 1 in equation( 2)
(1/3) ×(23/13)) log 1 = C
C = 8/3
From equation( 2), we get
⇒( y3/ 3x3) logx = 8/3
thus, the needed differential equation is y3 3x3logx = 8x3.
