Answer: Total cost is $1.75
Explanation:
Since we have given that
Number of postcards bought by Doug's family= 7
Cost of each postcard including tax = $0.25
Total cost is given by

Now, we want to show this in number line :
On the number line put all the number with a difference of 0.25 and run the number line seven times and we get the answer.
Each step is of length 0.25 and there are 7 jumps to reach required answer.
So, after 7 jumps we reach at 1.75 which is the required answer.
Hence total cost is $1.75
E^x is not zero for any finite value of x.
The number of values for which e^x is zero is zero.

Answer:
effective green time = 35 seconds
Step-by-step explanation:
given data
cycle length = 60 seconds
effective red time = 25 seconds
solution
we get here effective green time that is express as
effective green time = cycle length - effective red time ...........................1
put here value and we will get
effective green time = 60 seconds - 25 seconds
effective green time = 35 seconds
Answer:
$120
Step-by-step explanation:
I would like to rewrite your question for others easy to understand:
<em>"Three sisters want to Buy a pda for their father for fathers' day. The least expensive pda in the store is $360. Writen and slove an inequality to fund the least amout of money each girl would have ti contrubute if each contribute an equal amount" </em>
<em />
Let X is the the amount one girl contribute, we have 3 girls => 3X
The least expensive pda in the store is $360, so the total contributed amount must be equal or smaller than the pda cost
<=> 3X
<=> X
So the least amout of money each girl would have to contrubute is $120
