Answer:
- 7
Step-by-step explanation:
Solve for x
3x + 3 = - 9 ( subtract 3 from both sides )
3x = - 12 ( divide both sides by 3 )
x = - 4
Hence
3x + 5 = (3 × - 4) + 5 = - 12 + 5 = - 7
Option D: 3.47*10^-7 is the correct answer
Step-by-step explanation:
In order to determine the number written in standard scientific notation, first of all we have to understand how the scientific numbers are written
the scientific numbers are written in the form of:

Here
a is a number between 1 and 10 while the value of n can be only integer (positive or negative)
so,
In the given options:
Option A has a number larger than 10 in place of a so it is not in standard notation
Option B has a number less than 1 in place of a so it is also not in standard notation
Option C has a number larger than 10 in place of a so it is not in standard notation
Option D is in standard scientific notation as 1<3.47<10 and the power of 10 is integer
Hence,
Option D: 3.47*10^-7 is the correct answer

Answer:
2y
Step-by-step explanation:
Circumference of a circle having radius of 27 yard can be found using the formula, π = 2(Area of Circle)/r, which is C = 169.6 yd
<h3>What is the Circumference of a Circle?</h3>
- Circumference of a circle is the distance round the circle.
- Circumference = Perimeter
- Circumference of a circle without using π = 2(Area of Circle)/r.
Given:
radius of circle = 27 yd
Thus:
Area = πr² = π(27)²
Area = 2,290.2 yd²
Circumference of a circle without using π = 2(2,290.2)/27
= 169.6 yd.
