Mathwords.com gives this definition of “scale factor”: The ratio of any two corresponding lengths in two similar geometric figures. You can see immediately that the length of each of the sides in triangle DEF is equal to the length of the corresponding side in ABC multiplied by “a”.
Answer:
(12x9)+(9x50)= 112.50
Step-by-step explanation:
100 is the total
12.50 find what you can multiply for closest answer to 100
so 12.50 x 9 which is 108
but dont forget the 50cents so she has
$112.50
I think its right if you get it wrong sorry

Step-by-step explanation:
Answer:
$100.87 (to the nearest cent)
Step-by-step explanation:
1 gallon = 27 miles
⇒ number of gallons needed to drive 838 miles = 838 ÷ 27 = 31.0370370... gallons
1 gallon = $3.25
⇒ total cost to drive 838 miles = 3.25 x 838/27 = $100.87 (to the nearest cent)
Answer:
it will take a programmer about 16.67 times to work before they are fired
Step-by-step explanation:
From the information given;
The transistion matrix for this study can be computed as:
P M X
P 0.7 0.2 0.1
M 0 0.95 0.05
X 0 0 1
where;
The probability that the programmer remains a programmer = 
The probability that the programmer turns out to be a manager = 
The probability that the programmer is being fired = 
Thus, the required number of years prior to the moment being fired for an employee y(P), for programmer and y(M) for manager is represented by ;



y(M) = 
y(M) =20
y(P)=1+0.7y(P)+0.2y(M)
y(P) - 0.7y(P) = 1 + 0.2y(M)
0.3y(P) = 1 + 0.2(20)=1+4
0.3y(P) = 1 + 4
0.3y(P) = 5


Therefore, it will take a programmer about 16.67 times to work before they are fired
