Answer:
slove 6/7 then times it by 21
Step-by-step explanation:
If you are 600 m from a batter when you see him hit a ball, how long will you wait to hear the sound of the bat hitting the ball? (at 20ºC)?
Speed of sound at 20ºC =?
time =?
Answer:
The speed of sound at 20°C is 343.42 m/s.
You have to wait 1.75 seconds to hear the sound of the bat hitting the ball
Step-by-step explanation:
Speed of Sound
The speed of sound is not constant with temperature. Generally speaking, the greater the temperature, the greater the speed of sound.
The approximate speed of sound in dry air at temperatures T near 0°C is calculated from:
[tex]\displaystyle v_{\mathrm {s} }=(331.3+0.606\cdot T )~~~\mathrm {m/s}[/tex]
The air is at T=20°C, thus the speed of sound is:
[tex]\displaystyle v_{\mathrm {s} }=(331.3+0.606\cdot 20 )~~~\mathrm {m/s}[/tex]
[tex]v_{\mathrm {s} }=343.42\ m/s[/tex]
The speed of sound at 20°C is 343.42 m/s.
To calculate the time to hear the sound after the batter hits the ball, we use the formula of constant speed motion:
[tex]\displaystyle v=\frac{d}{t}[/tex]
Where d is the distance and t is the time. Solving for t:
[tex]\displaystyle t=\frac{d}{v}[/tex]
Substituting the values v=343.42 m/s and d=600 m:
[tex]\displaystyle t=\frac{600}{343.42}[/tex]
t = 1.75 s
You have to wait 1.75 seconds to hear the sound of the bat hitting the ball
PLEASE help me!!! I need help with this problem below.... what is the rule for the sequence 1.8, 2.85, 3.90, 4.95, 6 Please answer this with a clear step by step explanation before tomorrow And help me out! Thanks!
Answer:
The next term is equal to the previous term with an added 1.05.
Step-by-step explanation:
The given sequence is:
1.8, 2.85, 3.90, 4.95, 6
The first term is:
[tex]a = 1.8[/tex]
The second term is:
[tex]a_2 = 2.85[/tex]
The third term is:
[tex]a_3 = 3.90[/tex]
The fourth term is:
[tex]a_4 = 4.95[/tex]
The fifth term is:
[tex]a_5 = 6[/tex]
Let us have a look at the difference of each term:
Second term - First term = 1.05
Third term - Second term = 1.05
Fourth term - Third term = 1.05
Fifth term - Fourth term = 1.05
We can see that there is a common difference between each term of the given sequence.
Therefore, we can conclude that:
The given sequence is an Arithmetic Progression which has the difference of each term as equal.
First term, [tex]a = 1.8[/tex]
Common difference, [tex]d =1.05[/tex]
So, the rule is:
The next term is equal to the previous term with an added 1.05.
What is the slope of the line represented by:
5x-12y = 24
Answer:
5/12
Step-by-step explanation:
5x - 12y = 24
~Subtract 5x to both sides
-12y = 24 - 5x
~Divide -12 to everything
y = -2 + 5/12x
~Reorder
y = 5/12x - 2
Slope is represent by "m" in slope intercept form [ y = mx + b ]. As we can see m = 5/12 from the given information.
Best of Luck!
Find the solution of system of equations.
-6x-9y=-42
6x+5y=10
Answer:
X = -5, y = 8
Step-by-step explanation:
add the two equations together since the x‘s will cancel
-4y = -32
y = 8
then plug 8 in for y and solve
6x + 5(8) = 10
6x + 40 = 10
6x = -30
x = -5
Solve the inequality. Graph the solution. −9y ≤ 36
Step-by-step explanation:
Divide by -9 to eliminate the -9 on -9y but remember if you divide or multiply by a negative you will need to switch/turn-around the sign
y≥-4
Answer: y≥-4

Troy is considering two lawn care services. Premier Landscaping charges $15 for travel to Troy's house and $55 per hour for maintaining his lawn. Ace Landscaping does not have a travel fee, but charges $65 per hour for lawn maintenance. Part A Write a system of equations that represent the lawn care services.
Answer:
Cost for Premier Landscaping = [tex]55h+15[/tex]
Cost for Ace Landscaping = [tex]65h[/tex]
Where [tex]h[/tex] is the number of hours spent on lawn care.
Step-by-step explanation:
Given that:
Charges as per Premier Landscaping:
Fixed charges for travel to the house = $15
Per hour charges = $55
Let [tex]h[/tex] be the number of hours for which lawn care is done.
So, Charges for [tex]h[/tex] hours = Per hour charges [tex]\times[/tex] Number of hours =$55[tex]h[/tex]
Therefore, total cost = [tex]55h+15[/tex]
Charges as per Ace Landscaping:
Per hour charges = $65
Let [tex]h[/tex] be the number of hours for which lawn care is done.
Then Charges for [tex]h[/tex] hours = Per hour charges [tex]\times[/tex] Number of hours =$65[tex]h[/tex]
Therefore, system of equations that represent the lawn care services:
Cost for Premier Landscaping = [tex]55h+15[/tex]
Cost for Ace Landscaping = [tex]65h[/tex]
[tex]h>0[/tex]
Where [tex]h[/tex] is the number of hours spent on lawn care.
