$1,365 is the answer, (the third choice)
Answer:
The hypotenuse is 68
Step-by-step explanation:
To find the length of the hypotenuse of a a right angled triangle, we use the Pythagoras Theorem
c² = a² + b²
where c = hypotenuse, a = height, 32 and b = width, 60
Substitute the value 32 and 60 for a and b respectively in the above formula, and we will have
c² = 32² + 60²
c² = 1024 + 3600
c² = 4624
c = √4624
c = 68
Step-by-step explanation:
Step one:
The farmer sells his corn for $230 a metric ton
small surcharge = $25.
let the amount per metric ton be x
and let the total cost per x metric ton be y
the total cost function is
y=230x+25--------------1
The neighbor sells her corn for $230 a metric ton
he gives $15 rebate------<em>A rebate is a partial refund of the cost of an item</em>
let the amount per metric ton be x
and let the total cost per x metric ton be y
the total cost function is
y=230x-15----------------2
Step two:
Equating the two equation above
230x+25=230x-15
230x-230x=25+15
0=40
The result shows that based on the cost function of both farmer, there will never be an amount of corn that would make them have the same cost
Answer:
-12.8x - 20y + 8.4
Step-by-step explanation:
To do this you just multiply everything by negative 4
so we have 3.2x*-4 + 5y*-4 - 2.1*-4
This gives us
-12.8x - 20y + 8.4
The last term is positive because we multplied a negative by another negative
