Answer:
area or two triangular faces = 2 × 1/2 x 6× 4 = 24
area of three rectangular faces= 3x 5x10 = 150
total area = 174cm^2
B.The sum of two rational numbers is rational.
C.The product of two irrational numbers is irrational.
D.The product of two rational numbers is rational.
Answer:
x=1
Step-by-step explanation:
this is because in this scale drawing they x2 when they are changing the numbers so you have to think what number x2 would give you 8 and that number is 1. so then you test it out and apply it to your scale drawing and they are 20 and 8
The number of rows kept empty will be 4 in the meeting room.
The difference between every two successive terms in a sequence is the same this is known as an arithmetic progression (AP).
The arithmetic progression has wider use in mathematics for example sum of natural numbers.
As per the given,
Number of seats in one row = 9
Total number of seats = 126
Maximum number of possible rows =126/9 = 14 rows
Total number of people seated = 90
Number of rows filled = 90/9 = 10 rows
Empty rows = 14 - 10 = 4 rows.
Hence "In the meeting room, four rows will be left unoccupied".
