Answer:

1/2

Step-by-step explanation:

(1/16)^x

Let x = 1/4

(1/16)^ 1/4

Rewriting 16 as 2^4

(1/2^4)^ 1/4

We know that 1 / a^b = a^-b

(2 ^ -4)^ 1/4

We know that a^b^c = a^(b*c)

2^(-4*1/4)

2^-1

We know that  a^-b = 1/ a^b

2^-1 = 1/2^1 = 1/2

dimaraw [331]

Answer:

24.5 is the answer. It is not rounded.

Step-by-step explanation:

You have to work backwards on this problem.  153.86 divided by 3.14 = 49.  But 49 is only your diameter, so you have to divide by 2 to get radius.  49/2 = 24.5.

eimsori [14]

Answer:  

Year 10 Interactive Maths - Second Edition

Problem Solving

Linear equations are often used to solve practical problems that have an unknown quantity. We use a suitable pronumeral to represent the unknown quantity, translate the information given in the problem into an equation, and then solve the equation using the skills acquired earlier in this chapter.

Example 11

If a number is increased by 8, the result is 25. Find the number.

Solution:

Let x be the number.  Increasing x by 8 gives x + 8, which we are told is 25.  Therefore, x + 8 = 25.  Subtract 8 from both sides to find x = 17.  So, the number is 17.

Step-by-step explanation:
