Answer:21
Step-by-step explanation:
One = <AOB
two= <BOC
three = <COD
four = <DOE
five = <EOF
six = <AOC
Seven = <AOD
Eight = <AOE
Nine = <BOD
Ten = < BOE
Eleven = < BOF
Theres a bunch more but im not listing them
X - y = 2400/6 = 400 where x = speed of plane and y = speed of wind.
x + y = 2400/5 = 480 - flying with the wind
adding the 2 equations
2x = 880
x = 440
Speed of the plane with no wind = 440 mph
Answer:
Step-by-step explanation:
Calculate for the value of 
:
-Use <u>Distributive Property</u> on both left and right:
-Take 
and subtract 
:
-Add 
to both sides:
-Take 
and divide on both sides:
Therefore, the value of is 
.
Step-by-step explanation:
Answer:
- a) $56000
- b) DA = 2, GA = 10
Step-by-step explanation:
<u>Given</u>
- DA = A + B ⇒ $3000
- GA = A + 2B ⇒ $5000
- Number of A = 12
- Number of B = 22
<u>We can see from the equations that</u>
- GA - DA = B ⇒ $2000 and
- A = $1000 and B = $2000 in terms of profit
<u>So greater use of unit B brings greater profit. We don't want any unit is left over, so get this equation.</u>
Is the equation set to indicate use of the units A and B
<u>Solving we get </u>
<u>It this case all the units are used and profit is maximum</u>
- 2*$3000 + 10*$5000 = $56000
- Number of DA = 2
- Number of GA = 10
