Step-by-step explanation:
We have two sets of elements, we will call them A and B. Let's remember what does each symbol represents:
We say that A ⊆ B (A is included in B) if every element of A is also an element of B.
We say that A ⊂ B (A is strictly included in B) if every element of A is also an element of B, but there is at least one element of B that's not an element of A.
If we look our sets, we can see that all the elements on the second set are included on the first one. But the olives are on the first set and not in the second one. Therefore, the symbol that can be placed in the blank is
⊃.
If we only can use ⊂ or ⊆, without changes, the answer would be neither.
Answer:
The size of Isabella's pool is 220 liters.
Step-by-step explanation:
Let the size of Isabella's pool be 
liters, 
be the rate of fill, 
be the time of fill and 
be the volume of water filled in the pool.
As the rate of fill is constant,
Therefore, volume of water filled in the pool can be given as,
Volume of water left is given as 
From the table,
Volume of water left after 
minutes is 184 liters.
So, 
-------- 1
Volume of water left after 
minutes is 4 liters.
So, 
------------2
Multiply equation 1 by 6 and equation 2 by -1, we get
Now, we add the above equations, we get
Therefore, the size of Isabella's pool is 220 liters.
Given that ABC is a right angle triangle with m∠C=90°, m∠B=75° and AB=12cm.
Area of triangle =
=
So we need to find BC,AC now.
To find them let us take sinB and cosB.
SinB =
BC = 12* cos B = 12* cos 75
So, area =
= 72*sin(75)*cos(75)
= 36*(2sin(75)cos(75))
= 36*sin(150) = 18
Hence area of triangle is 18
Hope this helps tbh sorry I was a little late btw (:
She will have enough money to buy the coffee maker. after you take away the 2 bills, you are left with $27.02. if she buys the coffee machine, she will have $5.03 left.
or 129-40-63=26 - 22 = 4
