Answer:
v_0(initial velocity) v_f(final velocity) a(acceleration)
v_0=70 km/h v_f= 0 km/h( rest)
Kinematics equation is a=(v_f-v-0)/time
a=(0-70)/(7/3600) which means it decelerates at -36000 km/h
This number is humongous; I would advise you to re-check the problem and see if the the time it takes is 7 hours rather than 7 seconds. Notice that I put the time as 7/3600 because it is 7 seconds which should be converted to hours.
Answer:
18%
Step-by-step explanation:
The computation of the percentage of the total fixed costs per unit is shown below:
= Total fixed cost ÷ Total cost
where,
Total fixed cost = Fixed manufacturing overhead + administrative salaries
= $12 + $24
= $36
And, the total cost is $200
So, the percentage of the total fixed costs per unit is
= $36 ÷ 200
= 0.18 or 18%
Y= 1/2x +4

Answer: h = 17
Step-by-step explanation: As a general rule, if an equation has any fractions in it, try to get rid of those fractions as soon as possible.
The quickest way to get rid of a fraction is to multiply both
sides of the equation by the denominator of the fraction.
So in this problem, we can get rid of the fraction in our
first step by multiplying both sides of the equation by 4.
On the left, the 4's cancel and on the right, 1(4) is 4.
Now we have h - 13 = 4.
Since 13 is being subtracted from <em>h</em>, to get <em>h</em> by itself,
we need to add 13 to both sides of the equation to get h = 17.
Now, we can check our answer by plugging 17 back
into the original equation shown below in italics.


Answer:
