El perímetro de un terreno rectangular mide 232 m si se sabe que el largo es 8m mayor que el ancho cuáles son sus dominaciones
Answer:
Largo = 62m
Ancho = 54m
Step-by-step explanation:
[tex]P=232m\\ b=(x+8)\\ h=x[/tex]
[tex]P=2(h+b)\\ P=2(x+(x+8))\\ P=2(2x+8)\\ P=4x+16[/tex] → [tex]4x+16=232\\ 4x=232-16\\ 4x=216\\ x=\frac{216}{4}[/tex]
[tex]b=54m[/tex] [tex]x=54m[/tex]
[tex]b=x+8=(54)+8[/tex]

What is the area of the figure? Enter your answer in the box. in²
Answer:
[tex]112in^{2}[/tex]
Step-by-step explanation:
to find the area of the square we multiply the base x height so 10x10 which equals 100in^2.
to find the area of the triangle we multiply the base x height divided by 2 so to find the base 10-6 will give us the dotted line which equals 4. to find the height of the triangle we take 16-10 which equals 6. to find the area of the triangle we multiply 6x4/2 to make 12 in^2. to find the total area we add the triangle plus the square 100+12=112in^2
Solve the equation:
12x^2 + 4x - 1
Find the distance between these points. W(-6, -8), X(6, 8) 10 √8 20
Answer:
20 units.
Step-by-step explanation:
To find the distance between any two points, we can use the distance formula:
[tex]\displaystyle d_2 = \sqrt{(x_2-x_1)^2 + (y_2-y_1)^2}[/tex]
Let W(-6, -8) be (x₂, y₂) and X(6, 8) be (x₁, y₁).
Substitute and evaluate:
[tex]\displaystyle \begin{aligned}d & = \sqrt{(-8-8)^2 + (-6-6)^2} \\ \\ & = \sqrt{(-16)^2 + (-12)^2} \\ \\ & = \sqrt{400} \\ \\ & = 20 \end{aligned}[/tex]
Therefore, the distance between the two points is 20 units.
Two numbers whose product is 40 and sum is -22
Answer:
-2, -20
Step-by-step explanation:
x * y = 40 (1)
x + y = -22 (2)
Multiply by x on (2):
x^2 + xy = -22x
x^2 + 40 = -22x
x^2 + 22x + 40 = 0
(x + 2)(x + 20) = 0
x = -2, -20 (answer)

A piece of equipment costs $85,000 new but depreciates 15% each succeeding year.
Find its value after 10 years.
Answer: $16,734.32
Step-by-step explanation:
Make an exponential equation where y represents the price of the equipment and x represents the number of years
y = 85,000(1 - 0.15)^x
y = 85,000(0.85)^10
y = 16,734.32
Therefore, the price of the equipment after 10 years will be $16,734.32

Which number is greater and by how much? 600 or 600 decreased by 20% and then uncreased by 20% of the result
Answer:
600 is greater by 24
Step-by-step explanation:
We will decrease 600 by 20%.
20% of 600 = 120
600 - 20% of 600 = 480
We will now increase 480 by 20%
20% of 480 = 96
480 + 20% of 480 = 576
Is 576 more than 600?
No.
And how much more is 600 than 576?
24, because 600 - 576 = 24.
Find HCF 2x^5-4x^4-6x and x^5+x^4-3x^3-3x^2
Answer:
HCF = [tex](x + 1)[/tex]
Step-by-step explanation:
A common factor is a factor that is shared by two or more numbers (or, in this case, polynomials). The highest common factor (HCF) is found by finding all common factors of the two expressions and selecting the largest one.
Find HCF of [tex]2x^5-4x^4-6x \ \ \textsf{and} \ \ x^5+x^4-3x^3-3x^2[/tex]
Factor [tex]2x^5-4x^4-6x[/tex]
Factor out common term: [tex]2x(x^4-2x^3-3)[/tex]
Factor [tex]x^4-2x^3-3[/tex]: [tex]2x(x+1)(x^3-3x^2+3x-3)[/tex]
Factor [tex]x^5+x^4-3x^3-3x^2[/tex]
Factor out common term: [tex]x^2(x^3+x^2-3x-3)[/tex]
Factor [tex]x^3+x^2-3x-3[/tex]: [tex]x^2(x+1)(x+\sqrt{3} )(x-\sqrt{3} )[/tex]
Therefore, from inspection the HCF = [tex](x + 1)[/tex]

Two cubes each of volume 27^3cm are joined end to end to form a solid. Find the surface area. of resulting solid.
Given :-
Two cubes each of volume 27cm³ are joined to make a cuboid .To Find :-
The surface area of the resulting solid .Solution :-
Given that the volume of cube is 27cm³ . We know that the volume of cube is given by (side)³ .
So , if we assume each side to be a , then ,
[tex]\longrightarrow[/tex] a³ = 27cm³
[tex]\longrightarrow[/tex] a = ³√{27cm³}
[tex]\longrightarrow[/tex] a = ³√3³cm³
[tex]\longrightarrow[/tex] a = 3 cm .
Hence , if we join two cubes we will get a cuboid of length 3cm + 3cm = 6cm . (l)The breadth would be 3cm .( b)The height would be 3cm .(h)See attachment for figure .
And as we know that TSA of cuboid is ,
[tex]\longrightarrow[/tex]TSA = 2( lb + bh + hl )
[tex]\longrightarrow[/tex] TSA = 2 ( 6*3 + 3*3 + 3*6) cm²
[tex]\longrightarrow[/tex]TSA = 2 ( 18 +9 +18 )cm²
[tex]\longrightarrow[/tex] TSA = 2 * 45cm²
[tex]\longrightarrow[/tex] TSA = 90 cm²
Hence the new surface area of the solid is 90cm² .

Robert is purchasing shirts for his weekend soccer team. The shirts he wants to buy are normally $11 each but are on sale for $9 off. His team has a total of 9 players. How much will he spend to buy the shirts?
Answer:
He shall pay $18 to buy the shirts.
Step-by-step explanation:
each shirt cost after sale: $11 - $9 = $2
then 9 shirts for 9 players would cost: $2 * 9 = $18
For the shirts for his soccer squad, Robert will spend a total of $18 to buy the shirts for his soccer team.
Given that;
Robert is purchasing shirts for his weekend soccer team.
And, The shirts he wants to buy are normally $11 each but are on sale for $9 off.
The shirts are originally priced at $11 each, and they are on sale for $9 off.
Therefore, the discounted price per shirt is,
$11 - $9 = $2
Since Robert has a total of 9 players in his team, he needs to buy 9 shirts.
Hence, the total amount he will spend,
Total amount = Number of shirts × Discounted price per shirt
Total amount = 9 shirts × $2/shirt
Total amount = $18
Therefore, Robert will spend a total of $18 to buy the shirts for his soccer team.
