2.77083333333
Step-by-step explanation:
I assume. Do not hold me account for mistakes, I apologize if my work is incorrect. Have a good day/night :}
You can do this by finding the lengths of RT , RS and ST using the distance formula
RT = sqrt ((0- -5)^2 + (4 - -6)^2)
= sqrt (5^2 + 10^2) = sqrt 125
RS = sqrt ((-3- -5)^2 + (-2 - -6)^2))
= sqrt ( 2^2 + 4^2) = sqrt 20
ST = sqrt 125 - sqrt 20
RS / ST = sqrt 20 / (sqrt 125-sqrt 20)
so the ratio RS:ST = 2:3
Its B
I think it's false because that's not really a proportion.
Answer:
$36.00
Step-by-step explanation:
The cost performance index (CPI) is a measure of the financial effectiveness and efficiency of a project. As a ratio it is calculated by dividing the budgeted cost of work completed, or earned value, by the actual cost of the work performed, that is to say:
CPI = Budgeted cost of work / Actual cost of work
From the statement we know that:
CPI = 1.94
Budgeted cost of work= $69.85
Cost of work in 1983 = Budgeted cost of work / CPI
Cost of work in 1983 = $69.85 / 1.94 = $36.00
Answer:
Infinitely many solutions
Step-by-step explanation:
Because 4(x+2)=4*x+4*2=4x+8.
