Ram started his journey at 6:00 AM with an average speed at 20km/hr.
Hari started his journey two hours later (at 8:00 AM) with an average speed of 30km/hr.
We have to find time at which they meet each other[tex].[/tex]
★ Let they meet each other after t hours wrt 6:00 AM.
At that time, distance covered by ram must be equal to the distance covered by hari.
We know that,
distance = speed × time➤ Distance covered by Ram :
⭆ d₁ = v₁ × t
⭆ d₁ = 20 × t
➤ Distance covered by Hari :
Since hari started his journey after 2 hours so will take time = (t - 2) hours
⭆ d₂ = v₂ × (t - 2)
⭆ d₂ = 30 × (t - 2)
⭆ d₂ = 30t - 60
Now,
➠ d₁ = d₂
➠ 20t = 30t - 60
➠ 30t - 20t = 60
➠ 10t = 60
➠ t = 6 hrs
∴ They will meet at (6 + t) = 12PM
Hope It Helps!Answer: 12:00 pm (Noon)
Step-by-step explanation:
Let t represent the time (in hours) from 6:00 am
Use distance (d) = rate (r) × time (t)
Ram: time = t, r = 20 → d = 20t
Hari: time = t - 2, r = 30 → d = 30(t - 2)
Use Substitution method to solve the system of equations:
20t = 30(t - 2)
20t = 30t - 60
-10t = -60
t = 6
They travel the same distance when Ram rides his bike for 6 hours
and Hari rides his bike for 4 hours.
Ram: 6:00 am + 6 hours = 12:00 pm (Noon)
Hari: 8:00 am + 4 hours = 12:00 pm (Noon) [tex]\checkmark[/tex]

What is the equation of the line that passes through the point (-4, 4) and has a slope of 3/4
Answers
Answer:
y=3/4x+7
Step-by-step explanation:
You want to find the equation for a line that passes through the point (-4,4) and has a slope of 3/4.
First of all, remember what the equation of a line is:
y = mx+b
Where:
m is the slope, and
b is the y-intercept
To start, you know what m is; it's just the slope, which you said was 3/4. So you can right away fill in the equation for a line somewhat to read:
y=3/4x+b.
Now, what about b, the y-intercept?
To find b, think about what your (x,y) point means:
(-4,4). When x of the line is -4, y of the line must be 4.
Because you said the line passes through this point, right?
Now, look at our line's equation so far: . b is what we want, the 3/4 is already set and x and y are just two "free variables" sitting there. We can plug anything we want in for x and y here, but we want the equation for the line that specfically passes through the the point (-4,4).
So, why not plug in for x the number -4 and for y the number 4? This will allow us to solve for b for the particular line that passes through the point you gave!.
(-4,4). y=mx+b or 4=3/4 × -4+b, or solving for b: b=4-(3/4)(-4). b=7.
hope this answers your question sorry it's soo long i just like writing long stuff have a great day!!

La siguiente funcion representa el costo del alquiler de un auto, en soles, en funcion del X de dias que se requiera = F (X) = 50 + 80 X
Answers
Answer:
Dado que f (x) = 50 + 80x, obtenemos m = 80, esto significa que el costo aumenta en 80 cada día
Step-by-step explanation:
La siguiente función representa el costo del alquiler de un auto, en soles, en función del número x de días que se requiera: f(x) = 50 + 80x. ¿Cuánto vale su pendiente y qué representa? a) 130; representa que, por cada día de alquiler, el costo se incrementa en 130 soles. b) 80; representa que, por cada día de alquiler, el costo se incrementa en 80 soles. c) 50; representa que, por cada día de alquiler, el costo se incrementa en 50 soles. d) 30; representa que, por cada día de alquiler, el costo se incrementa en 30 soles
Answer:
La función es una función lineal. Una función lineal tiene la forma y = mx + b, donde m es la tasa de cambio de y con respecto a x, b es el valor de y en x = 0, x es una variable independiente (no depende de otras variables) ey es una variable dependiente (depende de otras variables)
Dado que f (x) = 50 + 80x, obtenemos m = 80, esto significa que el costo aumenta en 80 cada día
Calculate the force between two touching grapefruits each with a radius of 0.08 meters and a mass of 0.45 kg
Answers
The force between two touching grapefruits each with a radius of 0.08 meters and a mass of 0.45 kg is 5.27 * 10⁻¹⁰ N
Newton's law of gravitation is given by:
F = Gm₁m₂/r²
Where F is the force, m₁, m₂ are masses, r is the distance between the two masses and G is the gravitational constant = 6.67 * 10⁻¹¹ Nm²/kg²
Given that m₁ = m₂ = 0.45 kg, r = 0.08 + 0.08 = 0.16 m, hence:
F = 6.67 * 10⁻¹¹ Nm²/kg² * 0.45 kg * 0.45 kg / 0.16²
F = 5.27 * 10⁻¹⁰ N

Answers
Answer:
x < .4
Step-by-step explanation:
Please mark Brainliest when you’re able :)
Answer:
Step-by-step explanation:
Step 1 - replace the < with an =
3x + 4.7 = -1.5x + 6.5
Step 2 - subtract 4.7 from each side, and add 1.5x to each side
3x + 1.5x = 6.5 - 4.7
4.5x = 1.8
Step 3 - divide each side by 4.5
x = 1.8/4.5
x = .4
Step 4 - change the = back to <
x < .4
Just make sure when you do it this way you check the answer because if you solved by subtracting 3x and subtracting 6.5 you would end up with .4 = x this .4 < x which is false. So depending what number you get always plug in a number bigger and smaller into the original to check. In this case 0 and 1 work.
3(0) + 4.7 < -1.5(0) + 6.5
4.7 < 6.5 which is true.
3(1)+ 4.7 < -1.5(1) + 6.5
3+4.7 < -1.5 + 6.5
7.7 < 5 which is false
So we know the direction on our < is right.

Which is the best estimate of 61.4 + 88.3?
A. 100
B. 140
C. 150
D. 200
Answers
C.150
Step-by-step explanation:
It is the closest to the answer and you would get closest to that even without really needing to work anything out
The best estimation of summation 61.4 + 88.3 after rounding to the nearest whole number is 150.
How do round any digit?To round up or down tens place then we need to look at the unit place if it is less than 5 then we need to keep it as it and if it is greater than 5 then we need to round up tens digit.
Given the sum,
61.4 + 88.3
61.4 + 88.3 = 149.7
Now the decimal place is 7 and if the decimal place is greater than 5 then we can round up the digit.
So,
149.7 → 14(9 + 1) = 150
Hence "Summation 61.4 + 88.3 is best approximated as 150 after being rounded to the next whole number".

The range has to be within 1-5, if its over, we know we won't have to get the wrong answer. For me, I honestly guessed the number 3, but then I had to put in each number in the equation. 2 was the solution, because they ended up the same.
2 + (1.25 * 2)
2 + 2.5 = 4.5
10 - (2.75 * 2)
10 - 5.5 = 4.5
4.5 = 4.5
Therefore the answer is 2.
