Ram can travel 20km by a motorcycle in 1 litre of petrol.how far can he travel from 5 litres of petrol?Also,how much petrol will be needed to travel 750km.
Answer:
On 5 liters of petroleum he can go 100km.
He needs 37.5 liters of petroleum to go 750km.
Step-by-step explanation:
He goes 20km on 1 liter. Now we must find how far he can go on 5 liters.
1 * 5 = 5
20 * 5 = 100
The reason we multiplied was because we had to multiply 1 by 5 to get the number of liters of petroleum and what you to one side you must do to the other.
To find how many liters are needed to go 750km you must divide:
750/20 = 37.5
He needs 37.5 liters of petroleum to travel 750km.

A fire department’s longest ladder is 110 feet long, and the safety regulation states that they can use it for rescues up to 100 feet off the ground. What is the maximum safe angle of elevation for the rescue ladder?
Answer:
65.4 degrees
Step-by-step explanation:
sin theta = 100/110
theta = inverse sin (100/110)
theta = 65.4 degrees
Hope this helped!
The required maximum safe angle of elevation for the rescue ladder is 65.4°
What are trigonometric equations?These are the equation that contains trigonometric operators such as sin, cos.. etc.. In algebraic operations.
here,
Perpendicular distance = 100 ft
hypotenuse length = 110 ft
SinФ = perpendicular height/hypotenuse length
sin Ф= 100/110
Ф = inverse sin (100/110)
Ф = 65.4 °
Thus, the required maximum safe angle of elevation for the rescue ladder is 65.4°

Find the value of x that makes FGH~JKL
Answer:
Required Answer:-[tex]{:}\dashrightarrow [/tex][tex]\sf x-4=20[/tex]
interchange both sides[tex]{:}\dashrightarrow [/tex][tex]\sf x=20+4 [/tex]
[tex]{:}\dashrightarrow [/tex][tex]\sf x=24[/tex]
The value of x is 30 if the triangles FGH and JKL are similar after using the property of the similarity triangles.
What is the similarity law for triangles?It is defined as the law to prove that the two triangles have the same shape, but it is not compulsory to have the same size. The ratio of the corresponding sides is in the same proportions and the corresponding angles are congruent.
It is given that:
The triangle FGH and JKL are shown in the picture.
(x + 35)/20 = (x - 4)/8
Cross multiplication:
8(x + 35) = 20(x - 4)
8x + 280 = 20x - 80
20x - 8x = 280 + 80
12x = 360
x = 360/12
x = 30
Thus, the value of x is 30 if the triangles FGH and JKL are similar after using the property of the similarity triangles.

Can some please help me?? It’s do today also can you guys explain how to do it because it’s still More questions and I actually wanna learn how to do it
Answer:
-3
Step-by-step explanation:
Slope of a line is "rise over run". Pick two points on the line. For example, (0,4) and (1,1). As we move from the first point to the second, we move down 3 units and right 1 unit. So the slope is -3/1 = -3.
Here's an algebraic approach. If the two points are (x₁, y₁) and (x₂, y₂), then the slope is:
m = (y₂ − y₁) / (x₂ − x₁)
Plugging in our two points:
m = (1 − 4) / (1 − 0)
m = -3

La mediana es 3.
Step-by-step explanation:
En la ciudad se hizo la relación de hoteles según la lista de estrellas, la cual se ordena de menor a mayor. Entonces, el orden determinado es:
1, 1, 1, 1, 1, 1, 2, 2, 2, 2, 2, 2, 2, 2, 2, 2, 2, 2, 3, 3, 3, 3, 3, 3, 3, 3, 3, 3, 3, 3, 3, 3, 3, 3, 4, 4, 4, 4
La mediana de un conjunto de números es el número medio en el conjunto, una vez que los números han sido ordenados de menor al mayor, o, si hay un número par de datos, la mediana es el promedio de los dos números medios.
En este caso el conjunto posee 38 datos. Cuando el número de observaciones es par es posible calcular la mediana como:
[tex]Mediana=\frac{n+1}{2}[/tex] donde n es la cantidad de observaciones.
Entonces:
[tex]Mediana=\frac{38+1}{2}[/tex]
Mediana= 19.5
Esto indica que el valor de la mediana se encuentra en la observación cuya posición esta entre la 19 y la 20. Entonces el valor de la mediana será una media de los valores que están en la posición 19y 20. Estos números son 3 y 3. La media entre estos dos números es:
[tex]\frac{3+3}{2} =3[/tex]
La mediana es 3.

A european business has offered to donate to the Salvation Army, but they are requiring a detailed report on expenditures. Chase and his brother are tasked with converting distances measured in miles to kilometers. To estimate the number of kilometers, Chase takes the number of miles, doubles it and then subtracts 20% of the result. Alex, Chase's brother, first divides the number of miles by 5 and then multiplies the result by 8.
Answer:
Both processes are correct.
Step-by-step explanation:
Let the mile taken by Chase be 10miles .
He doubles it so it will be 20 and
20% of 20 will be 4
20-4 = 16km
Now Alex operations
(10/5 )*8 = 2*8= 16 km
In both cases the answer will be the same
1 mile = 1.60034 km
Now 10 miles = 16.00 34 km
which is the same as above.
Both the processes are correct.

Please help! This is my last question on the homework and it’s taking forever for me to do
Answer: y = x + 40
Step-by-step explanation: y = x + 40
First of all, the line starts at the y-axis on 40, which means the y-intercept is 40.
Second, the slope, Rise over run. y2 - y1 / x2 - x1, which is = to 50 - 40 divided by 15 - 5. That is 10 over 10 or 10/10. The slope of that is 1 so the slope is just x.
There are a few possible answers and they are
y - 40 = 1(x - 0)
y - 50 = 1(x - 10)
y - 60 = 1(x - 20)
=================================================
Explanation:
Pick two blue points from the graph. I recommend points that land on grid intersections so we can read the coordinates easily. Two such points are (0,40) and (10,50)
Use the slope formula to find the slope
m = (y2-y1)/(x2-x1)
m = (50-40)/(10-0)
m = 10/10
m = 1
The slope is 1.
Note how I subtracted the y coordinates, then did the same for the x coordinates in the same order, and divided the differences.
------------------
Since your teacher wants the answer in point slope form, we'll use this as our template
y - y1 = m(x - x1)
where m is the slope and (x1,y1) a the point the line goes through. We have infinitely many choices for (x1,y1) since there are infinitely many points on this line.
------------------
If we use (x1,y1) = (0,40), then we get
y - y1 = m(x - x1)
y - 40 = 1(x - 0)
which is one possible answer
------------------
If we use (x1,y1) = (10,50), then we get
y - y1 = m(x - x1)
y - 50 = 1(x - 10)
which is another possible answer
------------------
If we use (x1,y1) = (20,60), then we get
y - y1 = m(x - x1)
y - 60 = 1(x - 20)
which is another possible answer
------------------
So again there are multiple answers possible. The slope stays the same each time, but x1 and y1 change depending on which point you choose.

convert the equation into the slope-intercept.
Answer:
Not sure what you're equation is but this is how you would convert to slope intercept form:
Step-by-step explanation:
y=mx+b is slope intercept form where m is the slope and b is the y intercept. the x is just x so don't change that. graphing your equation might help you to convert. Hope this helps if I had the equation it would help more. :)
