Answer:
For
Car A : 30
Car B : 20
Step-by-step explanation:
Let the speed at which Car A travels be x and the time of travel be T. Recall that
speed = distance/time
Hence for Car A.
x = 90/T
T = 90/x
since Car B is B going 10 km/hr slower travels 60 km then
T = 60/(x - 10)
equating both equations
90/x = 60/(x - 10)
cross multiply
90(x - 10) = 60x
90x - 900 = 60x
90x - 60x = 900
30x = 900
Divide both sides by 30
x = 900/30
= 30
This is the speed of Car A : 30km/hr
The speed of Car B = 30 - 10 = 20 km/hr
A truck like the one shown delivers a load of gasoline to a gas station 3 times a week. The storage tank at the gas station holds 9 loads of fuel. How much more gas does the storage tank hold than the truck.
The truck hauls 2,700 gallons.
Answer:
21,600 gallons
Step-by-step explanation:
The truck hauls 2,700 gallons.
Given :
A truck load of gasoline = 2700 gallons
Capacity of storage tank = 9 loads
Gallons of fuel which storage tank can take :
9 loads
1 load = 2700 gallons
9 * 2700 gallons
= 24300 gallons
Hence, the storage tank holds (9 - 1) = 8 more loads of gasoline than the truck :
24300 gallons - 2700 gallons = 21600 gallons
A customer opens a savings account
that applies 4% compound interest
annually. If the initial investment is
$200.00, how much money will be in
the account at the end of two years?
Please explain
Answer:
$216.32
Step-by-step explanation:
The formula for compound interest is given as:
A = P(1 + r/n)^nt
Where:
A = Amount after t years= ??
P = Principal = Initial amount invested $200
r = Interest rate = 4%
t = time in years = 2
n = Compounding frequency = Annually = 1
First, convert R percent to r a decimal
r = R/100
r = 4%/100
r = 0.04 per year,
Then, solve our equation for A
A = P(1 + r/n)^nt
A = 200.00(1 + 0.04/1)^(1 × 2)
A = $ 216.32
The amount of money that will be in the account at the end of two years is $216.32

Solve the differential equation: y"-5y'+6y=0
The solution to the differential equation in this problem is given as follows:
y(t) = Ae^(3t) + Be^(2t).
How to solve the differential equation?The differential equation for this problem is given as follows:
y'' - 5y' + 6 = 0.
It is a simple linear and homogeneous second order differential equation, hence it can be solved with the characteristic equation method.
The characteristic equation for the differential equation is given as follows:
r² - 5r + 6 = 0.
The roots for the characteristic equation are obtained by finding the linear factors and using the factor theorem as follows:
(r - 3)(r - 2) = 0.
Hence:
r - 3 = 0 -> r = 3.r - 2 = 0 -> r = 2.These are real and non-repeated roots, hence the solution is given as follows:
y(t) = Ae^(3t) + Be^(2t).
In which A and B are constants depending on the initial conditions for the differential equation.

Sonia decides to leave a 14% tip after eating dinner at Fresh Catchery. If the bill is $27.78, how much should she pay?
Answer:
$31.67
Step-by-step explanation:
14/100x27.78= about 3.89
3.89+27.78=31.67
$31.67
The amount that Sonia will pay is $31.67.
Amount of bill = $27.78
Percentage of tip = 14%
Amount of tip = 14% × $27.78
= 0.14 × $27.78
= $3.89
Total amount to be paid will then be;
= $27.78 + $3.89
= $31.67
In conclusion, Sonia will pay $31.67.
