Dan completes the same distance in
of an hour.
Calculate Dan's average speed.
Question:
Lisa walks at an average speed of 6 km/h for 15 hours.
Dan completes the same distance in an hour. Calculate Dan's average speed.
Answer:
[tex]Speed = 90km/hr[/tex]
Step-by-step explanation:
Given
Lisa:
[tex]Speed = 6km/hr[/tex]
[tex]Time = 15\ hr[/tex]
First, we calculate the distance covered by Lisa:
[tex]Distance = Speed * Time[/tex]
[tex]Distance = 6km/hr * 15\ hr[/tex]
[tex]Distance = 90km[/tex]
So, Dan distance can be represented as:
[tex]Distance = 90km[/tex] --- Dan completes the same distance as Lisa
[tex]Time = 1\ hr[/tex] -- Time to complete the distance
Dan's average speed is:
[tex]Speed = \frac{Distance}{Time}[/tex]
[tex]Speed = \frac{90km}{1\ hr}[/tex]
[tex]Speed = 90km/hr[/tex]
Hence, Dan's average speed is 90km/hr

What quadrant is -12 and -16 in?
Answer:3
Step-by-step explanation:
Consider all four-digit numbers that can be made from the digits 0-9 (assume that numbers cannot start with 0). What is the probability of choosing a random number from this group that is less than or equal to 5000
Answer: 0.44
Step-by-step explanation:
First, let's count the total number of four-digit numbers.
Let's think it as four empty slots:
_ _ _ _
In each slot, we can put a single digit.
In the first slot, we have 9 options {1, 2, 3, 4, 5, 6, 7, 8, 9}
The zero is not an option here, because if there was a 0, this would be a 3 digit number, then the 0 can not be in the first slot.
For the second slot we have 10 options {0, 1, 2, 3, 4, 5, 6, 7, 8, 9}
for the third slot we have 10 options {0, 1, 2, 3, 4, 5, 6, 7, 8, 9}
for the fourth slot we have 10 options {0, 1, 2, 3, 4, 5, 6, 7, 8, 9}
The total number of combinations is equal to the product between the numbers of options for each slot, this means that we have:
Combinations = 9*10*10*10 = 9000
So there are 9000 different 4 digit numbers.
Now we want to find the probability of selecting a number at random that is equal or smaller than 5000.
Let's see the number of 4-digit numbers that are equal or smaller than 5000.
The smallest 4-digit number is 1000.
Then the number of numbers between 1000 and 5000 is:
5000 - 1000 = 4000
This means that there are 4000 4-digit numbers that are equal or smaller than 5000.
Now, the probability of selecting one of them at random is equal to the quotient between the number of 4-digit numbers that meet the condition (4000) and the total number of 4-digits (9000)
Then te probability is:
P = 4000/9000 = 4/9 = 0.44

-18=-5x-(-2) what is x?
Answer:
x = 4
Step-by-step explanation:
-18 = -5x-(-2)
i) when there is a '-' sign in front of an expression in parentheses, change the sign of each term in the expression-18 = -5x+2
ii) move -5x to the left-hand side and change its sign5x-18 = 2
iii) move -18 to the right-hand side and change its sign5x = 2+18
iv) add the numbers5x = 20
v) divide both sides of the equation by 5[tex] \frac{5x}{5} = \frac{20}{5} [/tex]
[tex]x = 4[/tex]
6. What is the y-value to the solution of
y = 5x -4
y = 2x + 8?
Answer:
y = 16, don't know if I'm 100% right but hope this helps.
Step-by-step explanation:
since they both equal Y they may be equal to each other
Then you would subtract 2x from both sides canceling it out on one side
2x + 8 = 5x - 4
-2x -2x
This would make the equation 8 = 3x - 4
next you add the 4 from both sides
8 = 3x - 4
+4 +4
This will leave you with 12 = 3x
now you divide 3 from both sides and 12/3 = 4 makes X = 4
next you take (4) and plug it in to one of the equations
y = 2(4) + 8
y = 8 + 8
y = 16

2. The new Ferrari can accelerate from rest to 100 km/hr in 5 seconds. What is the average acceleration of the car in m/s2?
3. A car starts from a stoplight and is traveling with a velocity of 10 m/sec east in 20 seconds. What is the acceleration of the car?
4. A ball is rolled at a velocity of 12 m/s. After 36 seconds, it comes to a stop. What is the acceleration of the ball?
Answer:
The answer is below
Step-by-step explanation:
Acceleration is the time rate of change in velocity. Acceleration is given by:
Acceleration = change in velocity / time taken
Acceleration = (final velocity - initial velocity) / time
1) The Ferrari is from rest, hence initial velocity = 0. The final velocity = 100 km/h = [tex]\frac{100\ km*1000\ \frac{m}{km} }{1\ hr*\frac{3600\ s}{1\ hr} } =27.78\ m/s[/tex], time = 5 s
Acceleration = (0 - 27.78) / 5 = 5.56 m/s²
2) The car has initial velocity = 10 m/s. The final velocity = 10 m/s since velocity is constant. time = 20 s
Acceleration = (10 - 10) / 20 = 0 m/s²
3) The ball has initial velocity = 12 m/s. The final velocity = 0 m/s since it stops. time = 36 s
Acceleration = (0 - 12) / 36 = -0.33 m/s²
Determine the input value for which the statement
f(x) = g(x) is true.
From the graph, the input value is approximately .
f(x) = 3 and g(x) = x – 2
3 = x – 2
5 = x
The x-value at which the two functions’ values are equal is .
Answer:
The x-value at which the two functions' values are equal is 5.
Step-by-step explanation:
Let [tex]f(x) = 3[/tex] and [tex]g(x) = x-2[/tex], if [tex]f(x) = g(x)[/tex], then:
[tex]x - 2 = 3[/tex]
[tex]x = 3+2[/tex]
[tex]x = 5[/tex]
The x-value at which the two functions' values are equal is 5.
Find the slope intercept equation of the line
Answer:
Y=2x-2
Step-by-step explanation:
Slope intercept form is also known as y=mx+b
The slope of a line is rise over run. In this case that would be 2/1 which simplifies to 2
The intercept is where the line crosses the y axis, which is at -2
So your equation would be y=2x-2
