i have 2 pinapple farms the rayio of their perimeter is 5:8 and the perimeter of the larger farm is 80 yards fencing cost$0.50 a yard if i want to buold a fence around the smaller farm how much will it cost me
Answer:
$40
Step-by-step explanation:
If the perimeter of the larger farm is 80 yards in a 8:5 ratio, the perimeter of the smaller farm will be 50 yards.
Multiply this value by the cost of 0.50 per yard to get $40.

An = 7 + (41-1)8 = 327
Answer:
327.
Step-by-step explanation:
T41 = a + (n-1) d.
T41 = 7 + ( 41 - 1) 8.
T41 = 7 + ( 40) 8.
T41 = 7 + 320.
T41 = 327.

Describe the graph of a quadratic function.
Answer:
The graph of a quadratic function is a U-shaped curve called a parabola. ... The extreme point ( maximum or minimum ) of a parabola is called the vertex, and the axis of symmetry is a vertical line that passes through the vertex. The x-intercepts are the points at which the parabola crosses the x-axis.

What is the equation in point-slope form of the line that passes through the points (7,5) and (−4,−1) ?
Answer:
-6/-11
Step-by-step explanation:
First we find the gradient.
Which is defined by the formula, y2-y1/x2-x1
In the coordinates given, y2= -1 y1= 5 x2= -4 x1=7
-1-5/-4-7 = -6.75 (this is the slope / gradient)
Therefore it is -6/-11
3 years ago, the ratio of Tina's age to Carl's age was 2:7
Tina is now 15 years old and Carl is now x years old.
Find the value of x
Answer: x = 45
Step-by-step explanation:
Given information
Tina's age (now) = 15 years old
Carl's age (now) = x years old
Ratio of age (3 years ago) = Tina : Carl = 2 : 7
Set equation according to the given information
(15 - 3) / (x - 3) = 2 / 7
Cross multiply
7 (15 - 3) = 2 (x - 3)
Simplify by subtraction in the parentheses
7 (12) = 2 (x - 3)
Simplify by multiplication
84 = 2 (x - 3)
Divide 2 on both sides
84 / 2 = 2 (x - 3) / 2
42 = x - 3
Add 3 on both sides
42 + 3 = x - 3 + 3
[tex]\boxed{x=45}[/tex]
Hope this helps!! :)
Please let me know if you have any questions
Answer:
x = 45
Step-by-step explanation:
Let the present age of Carl be x.
Given Tina's present age is 15 and 3 years ago, the ratio of Tina's and Carl's ages was 2:7
Then 3 years ago, Tina's age will be
[tex] \\ 15 - 3 = 12 \: years[/tex]
and, Carl's age will be x - 3
and they are in the ratio 2:7.
therefore,
[tex] \\ \: \: \: \: \: \: \: \: 12 \ratio(x - 3) = 2 \ratio7[/tex]
[tex] \\ \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \frac{12}{x - 3} = \frac{2}{7} [/tex]
[tex] \\ \sf \: by \: cross \: multiplication[/tex]
[tex] \\ \: \: \: \: \: \: 12 \times 7 = 2(x - 3) [/tex]
[tex] \\ \: \: \: \: \: \: x - 3 = \frac{84}{2} = 42[/tex]
[tex] \\ \: \: \: \: \: \: \: \: \: \: \: \: x = 42 + 3[/tex]
[tex] \\ \: \: \: \: \: \: \: \: \: \: \: \: \therefore \: \: x = 45[/tex]

Noah and James are each paid $15 per hour. However, this week Noah received a $60 bonus. Given that N and J represent the number of hours worked by Noah (N) and James (J), which expression can be used to represent their combined earnings for the week?
Answer:
15N+15J+60
Step-by-step explanation:
We know that Noah and James each receive $15 per hour. That means that to get the money one of them earned in a week, we multiply the money they earn ($15) by the hours they worked (N or J):
15 × N is what Noah earned.
15 × J is what James earned.
Combining those are just 15N + 15J. Then, we add the bonus Noah received ($60) to get their total combined earnings:
15N+15J+60
Answer:
15N+15J+60

Write 8x³y³ as the power of a product.
Answer:
(2xy)³
Step-by-step explanation:
According to the Power Rule of Exponents:
[tex](ab})^{m} = a^{m}b^{m}[/tex]
We can apply the Power Rule of Exponents to the given exponential expression, 8x³y³, by taking the smallest factor that when cubed (or raised to an exponent of 3), will produce the same results as the original exponential expression.
8 is a perfect cube of 2: ⇒ 2 × 2 × 2 = 2³ = 8
The cube of x is x³: ⇒ x × x × x = x³
The cube of y is y³ ⇒ y × y × y = y³
Hence, we can take the least common factors, (2xy) and raise them to the third power:
(2xy)³ = 2³x³y³ = 8x³y³
Therefore, the correct answer is: (2xy)³
[tex]\\ \sf\longmapsto 8x^3y^3[/tex]
8=2^3x^3=(x)^3y^3=(y)^3We know the rule of exponents
[tex]\boxed{\sf (ab)^m=a^mb^m}[/tex]
Now
[tex]\\ \sf\longmapsto 8x^3y^3[/tex]
[tex]\\ \sf\longmapsto 2^3x^3y^3[/tex]
[tex]\\ \sf\longmapsto (2xy)^3[/tex]
[tex]\\ \sf\longmapsto (2xy)(2xy)(2xy)[/tex]

what is the solution to[tex]\frac{5}{2 } x-7=\frac{3}{4} x+14[/tex]
Answer:
[tex]\boxed{\boxed{\sf x=12}}[/tex]
Step-by-step explanation:
[tex]\sf \cfrac{5}{2}\:x-7=\cfrac{3}{4}\:x+14[/tex]
Add 7 to both sides:
[tex]\sf \cfrac{5}{2}\:x-7+7=\cfrac{3}{4}\:x+14+7[/tex][tex]\sf \cfrac{5}{2}\:x=\cfrac{3}{4}\:x+21[/tex]Now, Subtract 3/4 x from both sides:
[tex]\sf \cfrac{5}{2}\:x-\cfrac{3}{4}\:x=\cfrac{3}{4}\:x+21-\cfrac{3}{4}\:x[/tex][tex]\sf \cfrac{7}{4}\:x=21[/tex]Multiply both sides by 4:
[tex]\sf 4\times \cfrac{7}{4}\:x=21\times \:4[/tex][tex]\sf 7x=84[/tex]Divide both sides by 7:
[tex]\sf \cfrac{7x}{7}=\cfrac{84}{7}[/tex][tex]\sf x=12[/tex]_________________________________identify the slope and the y-intercept

What’s the Problem/question ?
the HCF 12, 24 and 36
Answer:
HCF of 12, 24 and 36 by Euclidean Algorithm
As per the Euclidean Algorithm, HCF(X, Y) = HCF(Y, X mod Y)
where X > Y and mod is the modulo operator.
HCF(12, 24, 36) = HCF(HCF(12, 24), 36)
Steps for HCF(12, 24):
HCF(24, 12) = HCF(12, 24 mod 12) = HCF(12, 0)
HCF(12, 0) = 12 (∵ HCF(X, 0) = |X|, where X ≠ 0)
⇒ HCF(12, 24) = 12
⇒ HCF(HCF(12, 24), 36) = HCF(12, 36)
Steps for HCF(12, 36):
HCF(36, 12) = HCF(12, 36 mod 12) = HCF(12, 0)
HCF(12, 0) = 12 (∵ HCF(X, 0) = |X|, where X ≠ 0)
⇒ HCF(12, 36) = 12
Therefore, the value of HCF of 12, 24, and 36 is 12.
Step-by-step explanation:
factors of 12=1,2,3,4,6,12
factors of 24=1,2,3,4,6,8,12,24
factors of 36=1,2,3,4,6,9,12,18,36
common factors =1,2,3,4,6,12
Therefore factors of 12,24,36=12

expland and simplify 2(x+7) 3(x+1)
Answer:
2(x+7) = 2x+14 / 3(x+1) = 3x+3
Step-by-step explanation:
When you see equations with parenthesis, that means you must do distributive property. So, whatever number is outside of the parenthesis, you multiply it by all the number inside of the parenthsis.
Answer:
6x² + 48x + 42
Step-by-step explanation:
2(x + 7) 3(x + 1) ← multiply the integers
= 6(x + 7)(x + 1) ← expand factors using FOIL
= 6(x² + 8x + 7) ← distribute parenthesis by 6
= 6x² + 48x + 42
What is the point slope form of m=-2;(1,2).
I NEED HELP ASAP PLEASE. NO LINK.
Answer:
y - 2 = -2(x - 1)
Step-by-step explanation:
Point slope form is
y - y₁ = m(x - x₁)
where x₁ and y₁ are a point on the line
We are given (x₁, y₁) = (1, 2) and m = -2
plugging in
y - 2 = -2(x - 1)
Evaluate for the given value of the variable
Step-by-step explanation:
Example, i have 1 equation and i want to find x
2x - 1 = 5
2x = 5 + 1
2x = 6
x = 6/2
x = 3
So, value of x is 3

Can someone please help me with this math problem
Answer:
Option D) d (t ) = -0.25t + 2
Step-by-step explanation:
Given the water level covering a road after a rainstorm of 2 meters, for which the water level recedes at a rate of 0.25 meters per hour:
We can express the depth, d, of the water as a linear function of the time, t, in hours elapsed from the end of the rainstorm as:
d (t ) = -0.25t + 2
The receding rate has a negative value since it represents how the water level decreases over time.
Therefore, the correct answer is Option D: d (t ) = -0.25t + 2

a submarine descends 480 ft and 24 seconds the submarines elevation changes at a constant rate what is the elevation change of the submarine after 8 Seconds
Answer:
The submarine would be 900 below the ocean surface after 12 minutes assuming it started its descent at the surface of the ocean.
Step-by-step explanation:
The formula for distance traveled (in this case the distance a submarine descends) over a period of time is:
d
=
r
⋅
t
where
d
is the distance traveled (or descended),
r
is the rate of travel and
t
is the time.
In this problem we are told the rate,
r
is 75 feet per minute. And, we are told the time,
t
, to calculate for which is 12 minutes.
