Answer:
(6x6x6x6)x(6x6)
Step-by-step explanation:
6 to the power of 4 times 6 to the power of 2
If a number a is to the power of b, that means a multiplied by itself, b times
eg 4 to the power of 3 means 4x4x4
hence, 6 to the power of 4 (or superscript four) means 6 itself, 4 times
so, 6x6x6x6 multiplied by 6x6
Change the first to a decimal
15 2/5 = 15 4/10 = 15.4 miles
15.4 miles
------------
2.1 hours
7.33333333(repeating) miles/hour
7 1/3 miles per hour
Answer:
Total number of tables of first type = 23.
Total number of tables of second type = 7
Step-by-step explanation:
It is given that there are 30 tables in total and there are two types of tables.
Let's call the two seat tables, the first type as x and the second type as y.
∴ x + y = 30 ......(1)
Also a total number of 81 people are seated. Therefore, 2x number of people would be seated on the the first type and 5y on the second type. Hence the equation becomes:
2x + 5y = 81 .....(2)
To solve (1) & (2) Multiply (1) by 2 and subtract, we get:
y = 7
Substituting y = 7 in (1), we get x = 23.
∴ The number of tables of first kind = 23
The number of tables of second kind = 7
