Answer:
Step-by-step explanation:
P = {x : x is a real number between 2 and 7}
{x: 3,4,5,6}
Q = {x : x is all rational number between 2 and 7}
{4 }
We know that P contains all the rational numbers between 2 and 7.
And P ∪ Q and Q ∪ P each of them contain all the real numbers which are between 2 and 7.
{3,4,5,6}
Here Q is the proper subset of P
P ∩ Q = Q ∩ P = Q= {4}
Assuming Mark wants to buy a PS5 for $499.00 and the tax in her local county is 7.75% of the total sale, what will be the final cost is $538
Using this formula
Final cost =Total sales+ (Total sales×Tax)
Let plug in the formula
Final cost= $499.00+($499.00×7.75%)
Final cost= $499.00+$38.67
Final cost= $537.67
Final cost= $538 (Approximately)
Inconclusion Assuming Mark wants to buy a PS5 for $499.00 and the tax in her local county is 7.75% of the total sale, what will be the final cost is $538

Answer:
25,600
Step-by-step explanation:
You can use the rule of three considering that the number of dolls sold varies directly with the advertising budget:
$54,000 → 9,600
$144,000 → x

x=25,600
According to this, the number of dolls sold if the amount of advertising budget is increased to $144,000 is 25,600.
Answer:
WQ = 2.67 to the nearest hundredth.
Step-by-step explanation:
The area of triangle PQX = 1/2 * PX * QX.
The area of the rectangle = 8 * YX .
But YX = 2 PX so its area = 8 *2PX = 16*PX.
We are given that area of PQX is 1/6 of the area of WXYZ, so we have the equation:-
16 PX = 6* 1/2*PX * QX
16 = 3QX
QX = 16/3 = 5.33
Finally WQ = WX - QX
= 8 - 5.33
= 2.67
