Answer:

\$203.01

Step-by-step explanation:

we know that

The simple interest formula is equal to

A=P(1+rt)

where

A is the Final Investment Value

P is the Principal amount of money to be invested

r is the rate of interest  

t is Number of Time Periods

in this problem we have

<em>After 6 months</em>

t=6/12=0.5\ years\\ P=\$100\\r=2\%=2/100=0.02

substitute in the formula above

A_1=100(1+0.02*0.5)

A_1=100(1.01)

A_1=\$101

<em>At the end of one year</em>

t=6/12=0.5\ years\\ P=A_1+\$100=\$101+\$100=\$201\\r=2\%=2/100=0.02

substitute in the formula above

A_2=201(1+0.02*0.5)

A_2=201(1.01)

A_2=\$203.01

Thomas got a flat tire and had to walk 1/4 mile to the nearest gas station. How many feet did Thomas walk?
dusya [7]

Answer:

1320\ \text{feet}

Step-by-step explanation:

The distance Thomas walked to the nearest gas station is \dfrac{1}{4}\ \text{mile}.

The conversion factor for miles to feet is

1\ \text{mile}=5280\ \text{feet}

So

\dfrac{1}{4}\ \text{mile}=\dfrac{1}{4}\times 5280

=1320\ \text{feet}

Hence, Thomas had to walk 1320\ \text{feet} to get to the nearest gas station.

The table below represents a function that can be used to describe Katy's distance, f(x), in meters, from a bridge over a walkin
Lynna [10]
The x-intercept happens when y=0 which is at x=4 f(x)=0=y so the x-intercept is at (4,0)

the y intercept happens at x=0, reading from the table f(0)=-200 so the y intercept is (0,-200)

so the second option
x-intercept = (4,0)
y-intercept = (0,-200)

is correct

CAN SOMEONE PLEASE HELP ME WITH THIS QUESTION???
tangare [24]

Answer:

The complete answer is explained below.

Step-by-step explanation:

The problem is demanding to simply determine the number of years each color light would last.

We know the following information from the question:

  • As it is clear that a red light remains TURNED ON 50% of the time.
  • Green remains TURNED ON 42% of the time
  • Yellow remains TURNED ON 8% of the time.

Also the bulbs for each color are LED and are designed to last 100,000 hours. So, each light does last 100,000 hours.

lets make conversions

As

1\:day\:=\:24\:hours  

1\:year\:=\:365\:days

Dividing 100,000 hours by 24 hours would bring 4166.67 days

Dividing 4166.67 days by 365 days would bring 11.4 years, meaning 11 years and 4 months.

Keywords: light, conversion, day, hours
