Answer:
The required expression for total cost: ![0.17m+19.99d](https://tex.z-dn.net/?f=0.17m%2B19.99d)
The cost for renting car for 2 days and driving 70 miles is $51.88
Step-by-step explanation:
Consider the table shown below which repented the required options.
Car Rental Prices
:
Option 1 Option 2
$19.99 per day $50 fee
$0.17 per mi $0.17
Let d represents the number of days and m represents the number of miles.
you rent a car using option 1, For d days and m miles.
The required expression for total cost: ![0.17m+19.99d](https://tex.z-dn.net/?f=0.17m%2B19.99d)
Find the cost for renting car for 2 days and driving 70 miles
Substitute d=2 and m=70 in above expression.
![0.17(70)+19.99(2)](https://tex.z-dn.net/?f=0.17%2870%29%2B19.99%282%29)
![11.9+39.98](https://tex.z-dn.net/?f=11.9%2B39.98)
![51.88](https://tex.z-dn.net/?f=51.88)
Hence, the cost for renting car for 2 days and driving 70 miles is $51.88
Answer:
64, 16/25, .64 --- 12.5, 1/8, 0.125 --- 140, 1 2/5, 1.4 --- 275, 2 3/4, 2.75 --- 8, 2/25, 0.08
Step-by-step explanation:
Hope you get this in time! :D
Area=pi times radius^2
the 28 is a diameter
radius is 1/2 of diameter
28/2=14
area=pi times 14^2
pi=22/7 for this quesiton
area=22/7 times 14^2
area=22/7 times 196
area=4312/7
area=616 cm^2
answer is 616 square centimeers
Answer:
t=+4.06
Step-by-step explanation:
when the baseball hits the ground, the height will be 0.
h=0we are given that h=−16t2+64t+4.
this means that the height is 0 when −16t2+64t+4=0.−16t2+64t+4=0divide both sides by 4:−4t2+16t+1=04=0−4t2+16t+1=0 can be solved using the quadratic formula:t=−b±√b2−4ac2a, where at2+bt+c=0.at2+bt+c=−4t2+16t+1a=−4,b=16,c=1t=−b+√b2−4ac2aor−b−√b2−4ac2a−b+√b2−4ac2a=−16+√272−8=−0.06..−b−√b2−4ac2a=−16−√272−8=4.06 (3s.f.)we have 2 values for t:−0.06 and 4.06.
since time cannot be negative, only the positive value can be taken.
this is 4.06, to 3 significant figures.the time taken is 4.06 seconds.
The geometric sequence is adding 10 to each one to get the next number and so on.
