Answer:
140 ft
Step-by-step explanation:
Given data
Area= 14 square feet
Height a = 1/5 ft
Base b=????
We know that the area of a triangle is given as
Area= (1/2)B*H
substitute
14= 1/2* B* 1/5
14= B/10
cross multiply
B= 140
Hence the base is 140 ft
Answer: y≤0
Step-by-step explanation:
Looking at the question, I'm assuming the equation is
.
To find the range if this equation, it would be best to know that the graph of a square root looks like. Knowing that x=-5, the graph starts at -5 and then increases slowly to the right. Since there are no restrictions to this equation, the graph goes towards infinity.
Answer:

Step-by-step explanation:
Given
ID Card of 5 digits
Possibly Digits = {0,1...,9}
Required
Probability that a card has exact number 94213
First, we have o determine the total possible number of ID card numbers
Let the card number be represented by ABCDE
Given that repetition of digits is not allowed;
<em>A can be any of 10 digits</em>
<em>B can any of the remaining 9 digits</em>
<em>C can be any of the remaining 8 digits</em>
<em>D can be any of the remaining 7 digits</em>
<em>E can be any of the remaining 6 digits</em>
<em />
Total number of cards = 10 * 9 *8 * 7 * 6
Total = 30240
Provided that the card number is generated at random; each card number has the same probability of 
Hence, the probability of having 94213 is 
$4 an hour
5 hours per week times 8 weeks is 40 hours
$160 divided by 40 hours is $4/hr.
