Mario wants to put a rectangular fence around the pool in his backyard. Since one side is adjacent to the house, he will only need to fence three sides. There is one long side parallel to the house, and two shorter sides. He needs 130 feet of fencing to enclose the pool. The length of the long side is 10 feet less than twice the width. Find the length and width of the pool area to be enclosed.
Answer:
The length and width of the pool area is:
Length = 60 feet. Width = 35 feet.Step-by-step explanation:
Since the 130-foot fence should enclose only three parts of the pool (two wide and one long), equations are performed to express the information provided.
First an equation that says the total feet in the fence:
X + 2Y = 130 (where X is the length and Y is the width) X = 2Y-10 (since the length is 10 feet less than twice the width)With these equations, we proceed to replace the second equation in the first one and solve for Y:
X + 2Y = 130 2Y -10 + 2Y = 130 4Y - 10 = 130 4Y = 130 + 10 Y = 140/4 Y = 35 feetSince we already know that the width corresponds to 35 feet, we use the second equation to find the value of X:
X = 2Y-10 X = 2 (35) -10 X = 70 - 10 X = 60With which it is identified that the length is 60 feet.
To find the dimensions of the pool area, we can set up an equation using the given information. Solving the equation, we find that the width of the pool area is 35 feet and the length is 60 feet. Therefore, the dimensions of the pool area to be enclosed are 35 feet by 60 feet.
Explanation:To find the dimensions of the pool area, we will set up an equation based on the given information. Let's say the width of the pool area is 'w'. According to the problem, the length of the long side is 10 feet less than twice the width, so the length can be represented as 2w - 10. Since Mario needs to fence three sides, we can calculate the total length of the fence as follows:

Answer:
The house increases by $23,580 and he current value of the house is $285,580
Step-by-step explanation:
A house on the market was valued at $262,000. After several years, the value increased by 9%.
The first part of the question is to find by how much the house's value increase in dollars, to calculate this, we will simply find;
9% of $262,000
= [tex]\frac{9}{100}[/tex] × $262 000
= [tex]\frac{2358000}{100}[/tex]
=$23580
Therefore, the house's value increase by $23580
The second part of the question is to fin the current value of the house. Hence;
Current value of the house = $262,000 + $23580=$285,589
Therefore the current value of the house is $285,589

George has a mass of 65kg. What would George weigh on the Moon? (The gravitational field strength on the Moon is 1.6N/kg.)
George would weigh
65 kg × 1.6N /kg = 104 Newtons
That's compared to around 650 Newtons on earth.
Answer: Weight of George on Moon =104 N
Step-by-step explanation:
Given : George has a mass of 65 kg.
The gravitational field strength on the Moon is 1.6N/kg.
Then, the weight of George on Moon = George's Mass x Gravitational field strength
=[tex]65\times1.6=104\text{ Newtons}[/tex]
Hence, the weight of George on Moon =104 N
What is the polynomial function of least degree whose only zeros are -3, ,-2, and 4 ?
The polynomial function of least degree with zeros -3, -2, and 4 is f(x) = (x+3)×(x+2)×(x-4), which is a cubic polynomial.
The polynomial function of least degree with given zeros of -3, -2, and 4 is derived from the fact that if a polynomial has zeros at x=a, x=b, and x=c, then it can be represented as f(x) = k×(x-a)×(x-b)×(x-c), where k is any non-zero constant. Given the zeros -3, -2, and 4, the polynomial function is:
f(x) = k×(x+3)×(x+2)×(x-4)
Because the question does not specify a leading coefficient, we can assume k=1 for the least degree polynomial. Thus, the final form of the polynomial would be:
f(x) = (x+3)×(x+2)×(x-4)
Expanding this would give us a cubic polynomial, which is the polynomial of least degree that satisfies the condition of having exactly these three zeros.
Matthew invested $3,000 into two accounts. One account paid 3% interest and the other paid 8% interest. He earned 4% interest on the total investment. How much money did he put in each account?
Answer:
Mathew invested $600 and $2400 in each account.
Solution:
From question, the total amount invested by Mathew is $3000. Let p = $3000.
Mathew has invested the total amount $3000 in two accounts. Let us consider the amount invested in first account as ‘P’
So, the amount invested in second account = 3000 – P
Step 1:
Given that Mathew has paid 3% interest in first account .Let us calculate the simple interest [tex](I_1)[/tex] earned in first account for one year,
[tex]\text {simple interest}=\frac{\text {pnr}}{100}[/tex]
Where
p = amount invested in first account
n = number of years
r = rate of interest
hence, by using above equation we get [tex](I_1)[/tex] as,
[tex]I_{1}=\frac{P \times 1 \times 3}{100}[/tex] ----- eqn 1
Step 2:
Mathew has paid 8% interest in second account. Let us calculate the simple interest [tex](I_2)[/tex] earned in second account,
[tex]I_{2} = \frac{(3000-P) \times 1 \times 8}{100} \text { ------ eqn } 2[/tex]
Step 3:
Mathew has earned 4% interest on total investment of $3000. Let us calculate the total simple interest (I)
[tex]I = \frac{3000 \times 1 \times 4}{100} ----- eqn 3[/tex]
Step 4:
Total simple interest = simple interest on first account + simple interest on second account.
Hence we get,
[tex]I = I_1+ I_2 ---- eqn 4[/tex]
By substituting eqn 1 , 2, 3 in eqn 4
[tex]\frac{3000 \times 1 \times 4}{100} = \frac{P \times 1 \times 3}{100} + \frac{(3000-P) \times 1 \times 8}{100}[/tex]
[tex]\frac{12000}{100} = \frac{3 P}{100} + \frac{(24000-8 P)}{100}[/tex]
12000=3P + 24000 - 8P
5P = 12000
P = 2400
Thus, the value of the variable ‘P’ is 2400
Hence, the amount invested in first account = p = 2400
The amount invested in second account = 3000 – p = 3000 – 2400 = 600
Hence, Mathew invested $600 and $2400 in each account.

Yanni threw his paper airplane 15 1/2 feet. Adrian threw his paper airplane 3/4 of yanni's distance. What is the distance Adrian paper airplane? Explain how you found your answer
Answer:
19.125
Step-by-step explanation:
multiply 15.5 by 3 and then divide the answer by 4
Final answer:
To find the distance Adrian's paper airplane traveled, convert Yanni's distance to an improper fraction, calculate 3/4 of that, and then convert back to a mixed number. Adrian's paper airplane flew 11 5/8 feet.
Explanation:
The question asks us to calculate the distance Adrian's paper airplane traveled, given that it is 3/4 of the distance Yanni's airplane traveled, which was 15 1/2 feet. First, we need to convert Yanni's distance to an improper fraction. This gives us 31/2 feet. To find 3/4 of this distance, we multiply 31/2 feet by 3/4:
(31/2) × (3/4) = (31 × 3) / (2 × 4) = 93/8 feet.
Now, we convert the improper fraction back to a mixed number to find the distance. This gives us 11 5/8 feet (since 93 divided by 8 is 11 with a remainder of 5).
Therefore, Adrian's paper airplane traveled a distance of 11 5/8 feet.

Find the equation of the line passing through the given point and perpendicular to the given equation write your answer in slope intercept form. (3,4) and y= -4/9x-3
Answer:
Step-by-step explanation:
To find the slope of a line perpendicular to y = (-4/9)x - 3, take the negative reciprocal of this slope -4/9. The slope of the new line is thus 9/4.
Now we have this data to work with: m = 9/4, y = 4 and x = 3. Subbing this info into y = mx + b, to obtain the value of b, we get:
4 = (9/4)(3) + b, or
4 = 3/4 + b. Thus, b = 3 1/4, or b = 13/4.
The desired equation is
y = (9/4)x + 13/4.

in this diagram below, the 2 line segments are congruent. Find the value of x
Answer:
Step-by-step explanation:
because the two line segments are the same length-->
12+10-x=18
x=22-18=4
The question aims to determine the value of x for two congruent line segments, typically involving algebraic and geometric methods; however, no specific solution can be provided without the diagram.
Explanation:The question involves finding the value of x when given two congruent line segments in a diagram. This typically requires the use of algebraic methods or the application of geometric theorems to establish relationships between the lengths represented in the diagram and solve for x.
Without the specific diagram, we cannot provide the direct steps to solve for x.
However, the context suggests the use of equations to calculate lengths. Common strategies include setting equations equal to each other when line segments are congruent and simplifying to find x.
The mention of bisectors and lines intersecting at right angles can also imply the use of properties related to parallel and perpendicular lines or the Pythagorean theorem.
Remember, when equations have two solutions for x, it's necessary to consider which solution is consistent with the geometric context of the problem.

O f(2) = g(0) and f(4) = g(2)
O f(2) = g(4) and f(1) = g(1)
Answer:
first one. Since its X crosses or passes (2,0)
Step-by-step explanation:
The value of function represents with same domain f(x)= g(x) is f(2) = g(2) and f(0) = g(0).
We know that two functions f and g are said to be equal if:
(i) f and g have same domain D
(ii) for all x ∈ D, f(x) = g(x)
Thus, we must select the response that best captures the situation where f(x) = g. (x)
Considering the fact that f(x) and g(x) are defined on the same domain
If they are equivalent for all values of x in the domain, then f(x) = g(x).
Thus, f(2) = g(2) and f(0) = g(0)
