the lengths of the sides of a triangle are in the extended ratio 5:9:10. the perimeter of the triangle is 96 cm. what are the lengths of the sides?
Answer:
Step-by-step explanation:
The lengths of the sides are 5x, 9x, 10x.
5x+9x+10x = 24x = 96 cm
x = 4
20 cm, 36 cm, 40 cm
The sides of the triangle are 20 centimeters, 36 centimeters and 40 centimeters.
What is perimeter?A closed shape's perimeter is the sum of the lengths of its outside boundaries. The lengths of all the sides are added to determine the measurement.
Given:
The lengths of the sides of a triangle are in the extended ratio 5:9:10.
That means, the sides are,
5x, 9x, 10x.
And the perimeter of the triangle = the sum of all the sides.
96 = 5x + 9x + 10x.
5x + 9x + 10x = 96
24x = 96
x = 96/24
x = 4
The sides are:
5x = 5(4) = 20
9x = 9(4) = 36
10x = 10(4) = 40
Therefore, 20 centimeters, 36 centimeters and 40 centimeters are the sides of the triangle.

Number of green balls/ Total number of balls
= 30 green balls/90 balls
P(Green ball) = 1/3
João gosta muito de animais de estimação e de charadas. Certo dia um amigo perguntou-lhe quantos cachorros e quantos gatos ele tinha. Prontamente João respondeu com o seguinte enigma: "A soma do dobro do número de cachorros e do triplo do número de gatos é igual a 17. E a diferença entre o número de cachorros e de gatos é apenas 1". Será que você consegue desvendar esse enigma e descobrir quantos cachorros e quantos gatos João possui? a) 3 e 4 b) 4 e 2 c) 2 e 5 d) 1 e 6
Responda:
a) 3 e 4
Explicação passo a passo:
Deixei :
Número de cães = x
Número de gatos = y
2x + 3y = 17 - - - - (1)
x - y = 1 - - - - (2)
De (2)
x = 1 + y
Coloque em (1)
2 (1 + y) + 3y = 17
2 + 2y + 3y = 17
2 + 5y = 17
5y = 17 - 2
5y = 15
y = 15/5
y = 3
x = 1 + y
x = 1 + 3
x = 4
Número de cães = x = 4
Número de gatos = y = 3

is (-1,5) a solution to each system? y=2x+7
Answer:
Step-by-step explanation:
Plug (-1,5) into the equation y = 2x+7
5 = 2(-1)+7

Find the area of the base of a box of height 4cm and lateral surface area 120cm.sq if its length is twice its breadth.
Answer:
The area of the base of a box is 1800 cm².
Step-by-step explanation:
We have:
H: is the height = 4 cm
[tex]A_{l}[/tex]: is the lateral surface area = 120 cm
L = 2B
We can find the breadth of the base by using the lateral surface area and the height:
[tex] A_{l} = H*B [/tex]
[tex] B = \frac{A}{H} = \frac{120 cm}{4 cm} = 30 cm [/tex]
Now, if the length is twice its breadth we have:
[tex] L = 2B = 2*30 cm = 60 cm [/tex]
Hence, the area of the base is:
[tex] A_{b} = B*L = 60 cm*30 cm = 1800 cm^{2} [/tex]
Therefore, the area of the base of a box is 1800 cm².
I hope it helps you!

** if there is two responses **
Answer:
m∠CDE = 37°
Step-by-step explanation:
Since, AB║CD and AC is a transversal line.
∠EAB ≅ ∠ECD [Alternate interior angles]
m∠EAB = m∠ECD = 25°
m∠CED + m∠AED = 180° [Linear pair of angles]
m∠CED + 62° = 180°
m∠CED = 180° - 62°
= 118°
By triangle sum theorem In ΔCDE,
m∠CED + m∠CDE + m∠ECD = 180°
118° + m∠CDE + 25° = 180°
m∠CDE + 143° = 180°
m∠CDE = 37°

The length of a rectangle is 3 meters greater than 2 times the width. The perimeter of the rectangle is 30 meters. What is the length?
Step-by-step explanation:
Perimeter= 2( length+ width)
l= w+ 3
perimeter= 2(w+3+w)
30= 4w +6
4w= 24
w= 6
width = 6m
length = 6+3 = 9 m

Step-by-step explanation:
Perimeter= 2( length+ width)
l= w+ 3
perimeter= 2(w+3+w)
30= 4w +6

A trinomial has a degree of 2
A constant has a degree of 1
A cubic monomial has a degree of 3
I will mark as the top answers of you help me!
Answer:
The degree of a binomial is zero. The product of two binomials is not a polynomial. The sum of two polynomials is a polynomial. A monomial containing ^2 has a degree of three
The degree of the polynomial is found by looking at the term with the highest exponent on its variable(s). Examples: 5x2-2x+1 The highest exponent is the 2 so this is a 2nd degree trinomial.
Names of Degrees
Degree Name Example
0 Constant 7
1 Linear x+3
2 Quadratic x2−x+2
3 Cubic x3−x2+5
The degree of a cubic monomial is three. A quadratic polynomial is a trinomial. The degree of a binomial is two.
