What is the answer to 4+x+7 + x = 33 A. 11 B. -11 C. 12 D. 22

1 answer:

8 0

First move the numbers to the other side
x+x = 33-4-7
2x = 22
Next divided both sides by 2 to get x on its own
X=11
Therefore the answer is A

Please help find the percent of increase?!

otez555 [7]

First, work out the difference(increase) between the two numbers you are comparing. So, the difference would be 100-80, which will equal 20.

Then, divide the increase by the original number and multiply the answer by 100. So, that would be 20÷100, which would be 0.2, then it would be 0.2⋅100, so back to 20.

The percent of increase should be 20.

The top of a refrigerator has an area of 0.6 m^2. The height of the refrigerator is 180 CM. What volume does the refrigerator oc

emmainna [20.7K]

the volume (V ) of a cuboid is V = Ah

where A is the area of the base or top and h is the height

h = 180 cm = 1.8m

V = 0.6 × 1.8 = 1.08 m³

Express the following relations in the set builder notation. Then, determine whether it is reflexive, symmetric, transitive. Ple

pshichka [43]

Answer:

a)Reflexive, not symmetric, transitive

b)Reflexive, not symmetric, transitive

c)Not reflexive, symmetric, not transitive

d)Reflexive, not symmetric, transitive

Step-by-step explanation:

$R=\left \{ (a,b)\epsilon \mathbb{R} \times \mathbb{R} \mid a \leq b\right \}$

The relation R is reflexive for

$a\leq a$ for every real number a

it is not symmetric because 0 is less than 1, but 1 is not less than 0

it is transitive

$a\leq$ and $b\leq c\Rightarrow a\leq c$

So if aRb and bRc, then aRc

$R=\left \{ (m,n)\epsilon \mathbb{Z} \times \mathbb{Z} \mid \exists k\in \mathbb{Z} \ni m=kn \right \}$

R is reflexive because m=1.m for every integer m

R is not symmetric: 2 is a factor of 4, but 4 is not a factor of 2

R is transitive: if mRn and nRp if m=kn and n=qp, so m=(kq)p and kq is an integer , so mRp

$R=\left \{ (m,n)\epsilon \mathbb{Z} \times \mathbb{Z} \mid m\neq n\right \}$

R is obviously not reflexive because all numbers equals themselves

R is symmetric: if a different to b, then b different to a

R is not transitive: 1R2 and 2R1 (because 1 different to 2), but 1 = 1

$R=\left \{ A,B\mid A\subseteq B \right \}$

R is reflexive for every set A is a subset of itself

R is not symmetric {1,2} is a subset of {1,2,3} but {1,2,3} is not a subset of {1,2}

R is transitive: if A is subset of B and B is subset of C, then A is subset of C
