What is the expression and value of “six less than nine times the sum of a number and eight” when n = 5
Vikentia [17]

Answer:

The expression is 9(n + 8) - 6, the value is 111 ⇒ answer A

Step-by-step explanation:

* Lets explain how to solve the problem

- We have a statement:

" six less than nine times the sum of a number and eight"

- When we solve we will start by the last part

- The last part is the sum of a number and 8

- Assume that the number is n

∵ The sum is the answer of adding

∴ The sum of a number and eight is ⇒ n + 8

- Nine times the sum

∵ The sum is n + 8

∵ Nine times means multiply the sum by 9

∴ Nine times the sum is ⇒ 9(n + 8)

- Six less than nine times the sum

∵ Nine times the sum is 9(n + 8)

∵ Six less than means subtract 6 from nine times the sum

∴ Six less than nine times the sum is ⇒ 9(n + 9) - 6

*<em> </em><em>The expression is 9(n + 8) - 6</em>

- Lets evaluate the expression when n = 5

∵ 9(n + 8) - 6

∵ n = 5

∴ The value = 9(5 + 8) - 6

∴ The value = 9(13) - 6

∴ The value = 117 - 6

∴ The value = 111

* <em>When n = 5 the value of the expression is 111</em>

What is the volume of a sphere that has a diameter of 36 yd?
Katen [24]
Volume=(4/3)pi(r^3)

radius=1/2diameter
d=36
radius=1/2 36
radius=18


subsitute
volume=4/3 pi 18^3
volume=4/3 pi 5832
volume=23328/3 pi
volume=7776pi

aprox pi to 3.14
volume=7776 times 3.14
volume=24416.64




answer is 24416.64 yd^3

1=10^0 into logarithmic form
Tatiana [17]

Answer:

0 = log_{10} 1

Step-by-step explanation:

Base for the exponent and for the logarithm are the same!

10^0 is the <u>exponential</u> form where 10 is the base and 0 the exponent

log_{10} 1 is the l<u>ogarithm</u> form where 10 is the base

To solve log_{10} 1 =   ask the question :

To what power should I raise the base 10 to obtain the number 1 ?

The answer to the power 0 therefore

log_{10} 1 = 0

1 = 10^{0}   -is-the- exponential -form\\0 = log_{10} 1 - is -the -logarithmic -form
