The total number of mattresses that are sold in a year = 1,330
Percentage of King size mattresses sold = 30% = 30/100 = 0.3
Next, we have to calculate the actual number sold by using the formula given below:
Number of king size mattresses sold = Total mattresses sold in a year * percentage of king size mattresses sold
Number of King Size mattresses sold = 1,330*0.3 = 399
Number of king size mattresses sold = 399
Answer:
See explanation
Step-by-step explanation:
The distibutive property states that for all real numbers a, b and c
Draw a rectangle with length of (a+b) units and width of c units. The area of this rectangle is
Divide this rectangle into two rectangles: first rectangle with the length of a units and the width of c units and the second rectangle with the length of b units and the width of c units. The area of these rectangles are
These two rectangles together form initial rectangle, so the sum of the area of two smaller rectangles is the area of the bigger rectangle.
{11X+8Y=158
{5X+17Y=152
{55X+40Y=790

Y=6
Cost of the ticket for student is $6
22% liked neither.
Step-by-step explanation:
Given,
64% liked pop music.
52% liked rap music.
38% liked both type of music.
To find out the percentage of those liked neither.
Now,
Let, total number of student = 100
Number of students liked pop = 64
Number of students liked rap = 52
Number of students liked both = 38
So,
Number of students who liked only pop = 64-38 = 26
Number of students who liked only rap = 52-38 = 14
Hence,
Number of students who liked neither = 100 - (26+14+38) = 22
22% liked neither.
