El largo de una casa es el triple de su ancho. Si a la longitud se suma 40 metros y al ancho 1 metro, el área se triplica
Answer:
el ancho es de 8 metros y el largo es 3 * 8 = 24 metros
width is 8 meters and length is 3*8= 24 meters
Step-by-step explanation:
Spanish
Si el ancho de la casa de la casa es x, entonces el largo de la casa es 3x.
Entonces el área = largo * ancho
área = 3x * x = 3x²
3 multiplicado por área = 9x²
9x² = (3x + 40) (x + 1)
9x² = 3x² + 3x + 40x +40
9x² = 3x² + 43x +40
0 = -6x² + 43x +40
0 = 6x²- 43x - 40
6x²- 43x - 40 = 0
Usando ecuación cuadrática
a = 6, b = -43, c- = -40
x = - b ± √b²- 4ac / 2a
x = 43 ± √1849- 4 (6) (- 40) / 12
x = 43 ± √1849 + 960/12
x = 43 ± 53/12
x = 43+ 53/12 y x = 43-53 / 12
x = 96/12 y x = -10/12
x = 8 y x = - 5/6
Ignorando el valor negativo x = 8 el ancho es de 8 metros y el largo es 3 * 8 = 24 metros
English
The length of a house is three times its width. If 40 meters are added to the length and 1 meter to the width, the area is tripled
If the width of the house of the house is x then the length of the house is 3x.
Then the area = length * breadth
area= 3x*x= 3x²
3 times area= 9x²
9x²= (3x+40 )(x+1)
9x²= 3x²+ 3x +40x +40
9x²= 3x²+ 43x +40
0 = -6x²+ 43x +40
0 = 6x²- 43x - 40
6x²- 43x - 40= 0
Using quadratic equation
a= 6 , b= -43 , c-= -40
x= - b±√b²- 4ac/ 2a
x= 43±√1849- 4(6)(-40)/ 12
x= 43±√1849+960/ 12
x= 43± 53/ 12
x= 43+ 53/ 12 and x= 43- 53/ 12
x= 96/ 12 and x= -10/ 12
x= 8 and x= - 5/6
Ignoring the negative value x= 8 width is 8 meters and length is 3*8= 24 meters

A central angle of a circle that measures 2 radians intercepts an arc of length 10 cm. What is the length of the radius?
5 cm
10 cm
15 cm
20 cm
Answer:
5 cm
Step-by-step explanation:
Arc length (S) = 10 cm
Central angle [tex] (\theta) [/tex] = 2 radians
We need to find: radius of the circle (r)
[tex] \because S = r \theta [/tex]
[tex] \therefore 10 = r(2) [/tex]
[tex] \therefore r= \frac{10}{2} [/tex]
[tex] \therefore r= 5\: cm [/tex]
In ABC, m∠A=10 and m∠B=145. Select the triangles that are similar to ABC.
Answer:
A
Step-by-step explanation:
A triangle has 180 degrees.
So, 10 + 145 + x = 180
x = 25
This means that the angles in the triangle are:
10, 145, and 25
Using this information, only A has the same values so it is the answer
Classify this triangle by its sides and angles.
Answer:
right and scalene
Step-by-step explanation:
all the sides are different in length, so it's a scalene triangle, plus, it has a right angle, which makes it a right angled triangle.

Step-by-step explanation:
In October Sally drove 560 miles in her car.
The car travelled 34.5 miles for each gallon of petrol used.
Petrol cost £1.08 per litre.
1 gallon = 4.55 litres.
Work out the cost of the petrol the car used in October
Answer: £80
Step-by-step explanation:
First, we need to calculate the number of gallons used by Sally. This will be:
= 560 / 34.5
= 16.23 gallons
Since 1 gallon = 4.55 litres, we calculate the number of liters and this will be:
= 16.23 × 4.55
= 73.85 liters
Since Petrol cost £1.08 per litre, the cost of the petrol will be:
= £1.08 × 73.85
= ££79.758
= £80 approximately

how many ways can 5 friends sit together at the movies in 5 seats?
Answer:
120
Step-by-step explanation:
The number of friends is 5 and there are 5 seats only. So , we can find it out with the help of permutations ,
[tex]\implies ^n P_r = \dfrac{n! }{(n-r)!} [/tex]
⇒ 5! / (5-5)!
⇒ 5! / 1!
⇒ 5!
⇒ 5 × 4 × 3 × 2 × 1
⇒ 120
Hence there are 120 ways by which 5 friends sit together at the movies in 5 seats.Sarah is going on a trip. She drives for 1 hours and 40 minutes, rests for 25 minutes and drives for another 1 hours 45 minutes. What is her total travel time in hours and minutes
Answer:
3 hours and 50 minutes
Step-by-step explanation:
Given that
Sarah drives for 1 hours and 40 minutes
And, rest for 25 minutes
And, then drive for another 1 hour & 45 minutes
We need to find out the total travel time in hours and minutes
First we convert into minutes i.e.
= 1 hour + 40 minutes + 25 minutes + 1 hours + 45 minutes
= 60 minutes + 40 minutes + 25 minutes + 60 minutes + 45 minutes
= 230 minutes
i.e.
3 hours and 50 minutes
