Si un automóvil tiene 1.500 kg de masa y una velocidad de 5 m/s, ¿cuál es la energía cinética de un automóvil?
Answers
Answer:
E = 18750 J
Step-by-step explanation:
The question is "If a car has a mass of 1,500 kg and a speed of 5 m / s, what is the kinetic energy of a car?"
Mass, m = 1500 kg
Speed, v = 5 m/s
We need to find the kinetic energy of the car. The formula for kinetic energy is given by :
[tex]K=\dfrac{1}{2}mv^2\\\\K=\dfrac{1}{2}\times 1500\times (5)^2\\\\K=18750\ J[/tex]
So, 18750 J is the kinetic energy of the car.
Jackie runs and rides her bike. She runs 6 miles an hour. She bikes 18 miles an hour. Last week she ran and bikes a total of 216 miles. It took her 16 hours. How many hours did Jackie run and bike last week. Show your work
Answers
Answer: she bikes for 10 hours and runs for 6
Step-by-step explanation: suppose that x equals the amount of hours she runs and y equals the amount of hours she bikes.
6x+ 18y=216
x+y=16
(This is your system of equations)
(Starting with the second equation, x+y=16)
y=-x +16 (move x to the other side by transposition)
Now that you have something that equals Y you plug it in to the other equation:
6x+18(-x+16)=216
(Start solving)
6x-18x+288=216 (used distributive property)
-12x+288=216 (Combine like terms)
-12x=-72 (use transposition again)
x=6 (divide to get x by itself)
Now you plug in the value of x into your equation for the value of “y”, y=-x+16,
Y=-6+16 (plugged in the value of x)
Y=10 (solved the equation -6+16)

Petrov ran 7 laps around a track.Each lap around the track is a distance of 1/4 mile. What is the total distance Petrov ran in feet?
Answers
Answer:
9240 feet
Step-by-step explanation:
Petrov ran 7 laps around a track.Each lap around the track is a distance of 1/4 mile.
Step 1
The total distance Petrov ran in miles is calculated as:
1 lap = 1/4 mile
7 laps = x mile
Cross Multiply
x = 7 × 1/4 mile
x = 1.75 miles
Step 2
What is the total distance Petrov ran in feet?
1 mile = 5280 feet
1.75 miles = x
Cross Multiply
x = 1.75 × 5280 feet
x = 9240 feet
Therefore, the total distance Petrov ran in feet is 9240 feet

Question 20:- Fahein is interested in purchasing an AC too. He will give three times more points to energy efficiency and two points more to noise levels than sevices and installation. Whereas, design features don't matter to him. In this case he devises a way to compare the 5 models. Which one is the correct formula given his preferences?
Answers
Answer:
[tex]Total = 3E + 2N + S[/tex]
Step-by-step explanation:
Given
Represent
Efficiency with E; Noise Level with N
and Service and Installations with S
Required
Determine the correct formula
From the question
3 points goes to E: i.e. 3E
2 points goes to N: i.e. 2N
The above is the number of points more than service and installations.
So 1 point will be given to S i.e. S
The total or formula is:
[tex]Total = 3E + 2N + S[/tex]

Which function is equivalent to g(x) = 9 x2 - 24 x + 16?
Answers
Answer:
Step-by-step explanation:
discriminant = (-24)² - 4(9)(16) = 0, so there are two identical roots.
That eliminates choices 2 and 4.
Quadratic formula
x = [24 ± √(24² – 4·9·16)] / [2·9]
= 24 / 18
= 4/3
9x² - 24x + 16 = 9(x-4/3)² = (3x-4)²
