Answer:
Unitary cost= $37.34 = $37
Step-by-step explanation:
Giving the following information:
Number of tires= 8
Total cost= $298.75
<u>To calculate the unitary value of each tire, we need to use the following formula:</u>
Unitary cost= total cost / number of tires
Unitary cost= 298.75 / 8
Unitary cost= $37.34 = $37
In
order to solve for a nth term in an arithmetic sequence, we use the formula
written as:<span>
an = a1 + (n-1)d
where an is the nth term, a1 is the first value
in the sequence, n is the term position and d is the common difference.
</span><span>THIRD
</span><span>A3=4+(3-1)(-5)
A3 = -6
A(3)=-2(3-1)(-5)
A3 = 20
</span><span>
FIFTH
</span>A5=4+(5-1)(-5)
A5 = -16
A(5)=-2(5-1)(-5)
A5 = 40<span>
TENTH
</span>A10=4+(10-1)(-5)
A10 = -41
A(10)=-2(10-1)(-5)
A10 = 90
To find the average speed for the whole race, you just have
to add the speed from a starting marker and the speed from the turnaround
marker going back and divide it by 2 since there are only two speeds involved.
10 m/s + 16m/s = 26 m/s / 2 = 13 m/s
Therefore, the average speed for the whole race is 13 m/s.
Answer:
$46.00
Step-by-step explanation:
$46.00 - $20 + $5 = $21
<h2>
Hello!</h2>
The answer is:
The distance to over by Adam to get to the park is 108 miles.
<h2>
Why?</h2>
To solve the problem, we need to write two equations using he given information about the times and his speed.
So,
For the first equation we have: Travel to Disney Park
For the second equation we have: Travel back from Disnery Park
Then, if Adam covered the same distance going and coming back, we have:
We have that the speed when he was going to Disney Park was 27 mph.
Now, to calculate the distance, we need to substitute the obtained speed in any of the two first equations.
Therefore, substituting the speed into the second equation, we have:
Hence, we have that the distance that Adam should cover to get to the park is 108 miles.
Havea nice day!
