Answer:
12
Step-by-step explanation:
Plug the given values into the equation to solve.
a² - b²
(4)² - (-2)²
16 - 4
12
So 22.5 per barrel
so 22.5
x represents the number of 22.5 barrels
y represents the number of 35 barrels
so
x+y=1250
then find the total cost
1250 barrels
27.5 per so mutiply by 1250 and get 34375 total cost
22.5x+35y=34375
we have 2 senctances
x+y=1250
22.5x+35y=34375
elimination
mulitply first equation by -35 to clear y
-35x-35y=-43750
add to second equation
-35x-35y=-43750
<u>22.5x+35y=34375 +</u>
-12.5x+0y=-9375
-12.5x=-9375
multiply -1
12.5x=9375
divie both sides by 12.5
x=750
subsitute
x+y=1250
750+y=1250
subtract 750
y=500
750 barrells of the 22.5 oil should be included and
500 barrells of the 35 oil should be included
Answer:
{w} is the SUBSET of {s,w,n,t,c}
Step-by-step explanation:
SUBSET: Any set P is called a SUBSET of a set Q is ALL ELEMENTS of P are in the set Q.
i.e P ⊂ Q
Here, the given set Q = {s,w,n,t,c}
Also, set P = {w}
Now,as the element w of set P is also an element of set Q.
⇒ P is the SUBSET of Q
⇒ P ⊂ Q
⇒ {w} ⊂ {s,w,n,t,c}
Hence, {w} is the SUBSET of {s,w,n,t,c}.
