Answer:
13.5
Step-by-step explanation:
equilateral triangle (all sides are equal) thus, if one side is 4.5 u will need to take 4.5x3=13.5
Well let me help.
For the first Question, the question is asking for the perimeter of the plot so assuming the plot is a rectangle, the perimeter will be (2*3)+(2*4.3)
=6+8.6
=14.6km.
Question 2
The problem involves finding the perimeter of the triangular garden. since the garden is an equilateral triangle, the perimeter will be thrice the side given ("equilateral" means "equal sided triangle"). So the answer will be 3*4.5
= 13.5 km.
Question 3
Same type of question as Q2 but this type is isosceles triangle (only two equal sides with one being different)
So the perimeter will be (2*15)+20
=30+20
=50km.
I hope this'll help

Answer:
(-2, 28)
(-1, 24)
(0, 20)
Step-by-step explanation:
You can plug any numbers in for x, and solve for y.
Example: 4(-2) + y =20 multiply 4 and -2
-8 + y = 20 add 8 to both sides
y = 28

Answers
Answer:
Step-by-step explanation:
First, lets simplify everything in the parenthesis.
(3×10^2 )×(2×10^−4 )=
In the parenthesis, since exponents come before multiplication in the order of operations, we need to do the exponents first.
(3 • 100) • (2 • 1/10^4)
Now, we can just multiply everything from left to right to get:

La suma de dos números es 81. La diferencia de los mismos dos números es 33. Escribe un sistema de ecuaciones para representar esta situación. Luego encuentra los números.
Answers
Answer:
a) Escribe un sistema de ecuaciones para representar esta situación.
x + y = 81 ...... Ecuación 1
x - y = 33 ....... Ecuación 2
b) Los dos números son: 57 y 24
Step-by-step explanation:
Estamos tratando con 2 números
Dejar
El primer número = x
El segundo número = y
La suma de dos números es 81.
x + y = 81 ...... Ecuación 1
La diferencia de los mismos dos números es 33.
x - y = 33 ....... Ecuación 2
Escribe un sistema de ecuaciones para representar esta situación.
x + y = 81 ...... Ecuación 1
x - y = 33 ....... Ecuación 2
Resolvemos estas ecuaciones usando el método de eliminación
Restamos la ecuación 2 de la ecuación 1 para eliminar
2y = 48
y = 48/2
y = 24
Resolver para x usando la Ecuación 1
x + y = 81 ...... Ecuación 1
x + 24 = 81
x = 81 - 24
x = 57
Por lo tanto, los dos números son: 57 y 24

A football team plays a total of 30 matches in the league. If we know that it has lost in 3 10 of the matches and has taken 3 draws to find out how many matches he's lost.
Answers
Answer:
The team lost 9 matches
Step-by-step explanation:
Given
[tex]Matches = 30[/tex]
[tex]Lost = \frac{3}{10}[/tex] of the matches
[tex]Draw = 3[/tex]
Required
Determine the number of matches lost
From the question, we have:
[tex]Lost = \frac{3}{10}[/tex] of the matches
Mathematically, this is:
[tex]Lost = \frac{3}{10} * Matches[/tex]
Substitute 30 for Matches
[tex]Lost = \frac{3}{10} * 30[/tex]
[tex]Lost = \frac{3* 30}{10}[/tex]
[tex]Lost = \frac{90}{10}[/tex]
[tex]Lost = 9[/tex]
The team lost 9 matches
Len has a rectangular wooden deck that measures 14 feet by 25 feet that he wants to put a sting of light around. what length of lights should he buy?
Answers
Answer:
78 feet
Step-by-step explanation:
assuming it's the perimeter
25 + 25 + 14 + 14 = 78
The length of the string of the lights is 78 feet.
What is the perimeter of the rectangle?P = 2(l + w), where 'l' is the length of the rectangle and w is the width of the rectangle
For given example,
Len has a rectangular wooden deck that measures 14 feet by 25 feet that he wants to put a string of light around.
The length of the string of the lights = the perimeter of the rectangular wooden deck
Here, length of the deck (l) = 25 ft.
width of the deck (w) = 14 ft.
Using the formula of the perimeter of the rectangle,
⇒ P = 2 × (l + w)
⇒ P = 2 × (25 + 14)
⇒ P = 2 × 39
⇒ P = 78 ft.
The perimeter of the rectangular wooden deck is 78 feet.
Therefore, the length of the string of the lights is 78 feet.

Sam and Bethan share £54 in the ratio 5:4
Work out how much each person gets.
Answers
Answer:
Sam: $30; Bethan: $24
Step-by-step explanation:
Since the ratio is 5:4 Sam has to pay 5/9 of the total which is 54. To find how much he pays set up the equation like this.
[tex]\frac{x}{54} =\frac{5}{9}[/tex]
Cross Multiply
54(5)=9x
270=9x
Divide by 9
30=x
So Sam pays $30. To find out how much Bethan pays simply subtract 30 from 54
54-30=24
So Bethan pays $24

what calculation can be used to find the value of p in the equation p^3 =8
Answers
Cube Root
[tex] {p}^{3} = 8 \\ p = \sqrt[3]{8} \\ p = \sqrt[3]{ 2\times 2 \times 2} \\ p = 2[/tex]
Formula
[tex] {p}^{3} - 8 = 0[/tex]
Use the following formula.
[tex] {x}^{3} - {y}^{3} = (x - y)( {x}^{2} + xy + {y}^{2} )[/tex]
[tex](p - 2)( {p}^{2} + 2p + 4)[/tex]
The expression p²+2p+4 has the discriminant less than 0 ( D < 0 ).
Thus, remove the expression and leave only p-2
[tex]p - 2 = 0 \\ p = 2[/tex]
Substitution
The most obvious number that multiplies itself three times and equal 8 is 2.
Substitute p = 2
[tex] {p}^{3} = 8 \\ {2}^{3} = 8 \\ 2 \times 2 \times 2 = 8 \\ 8 = 8[/tex]
The equation is true, thus 2 is the answer.
