Answer:
$140
Step-by-step explanation:
10 is 1/3 of x.
10=1/3x
x=30
x is 1/5 of y
30=1/5y
150=y
y-10=z
150-10=z
z=140

Answer:
<h2>(a) 5,050 psi.</h2><h2>(b) 5,051.3 psi.</h2><h2>(c) 5,180 psi.</h2><h2>(d) 4,920 psi.</h2>
Step-by-step explanation:
The given function is
Where 
represents the accelerated strength in psi, and 
represents 28-day standard-cured strength in psi.
Part a is about finding the y-value for 
Therefore, the expected value of 28-day strength when accelerated strength is 2,500, is 5,050 psi.
Part b is about the y-value for 
Part c is about the y-value for 
Part d is about the y-value for 
a. define variables for the quantities that are changing (be specific).
We define variables:
t = time in second
d = distance traveled
The variables that are changing are t and d.
As the time increases, the distance decreases.
b. what does it mean to say bob walks at a constant speed of 9.3 feet per second?
It means that for every second that passes, Bob walks 9.3 feet.
c. consider the formula d = 4320 - 9.3t i. what does t represent? ii. what does 9.3t represent? iii. what does d represent?
For this case we have:
t = represents the time in seconds
9.3t = represents the distance traveled by Bob
d = represents the distance Bob must travel to get to the bus stop.
