a circular fountain has a radius of 9.4 ft find its circumstance to the nearest hundredth using pi over3
Answers
= 2*3*9.4
=56.4 (to nearest hundredth)
therefore the circumference of the circular fountain is 56.4 feet to the nearest hundredth.

Answer:
4.2 × 10⁻⁵
Step-by-step explanation:
The decimal point must be after the first non-zero digit.
⇒ 4.2
Multiply 4.2 by a number that results in 0.000042. That number is 0.00001 or 10⁻⁵.
⇒ 4.2 × 10⁻⁵
Answer:
Sci. Notation= 4.2 x 10 to -5th power
Step-by-step explanation:
1. Go to decimal and move between 4 and 2
2. the number of zeroes after the the initial place of the decimal is the power it goes to
3. you pass four zeroes and the 4 which gives you five places, and the -5th power

which new equation would be the result of adding the equations together?
4x=2
8x=2
8x=12
y=12
Answers
Answer:
8x=12 cause y would cancel out and then you just add 2 and 6, and 7 and 5.
Final answer:
When the given system of equations is added together, the y terms cancel each other out, leaving '8x = 12' as the result.
Explanation:
Given the system of linear equations:
2x + 0.5y = 7
6x - 0.5y = 5
When we add these two equations together, the y terms will cancel out because one is positive (+0.5y) and one is negative (-0.5y). Thus, we will be left with the x terms and the constants. Adding the x terms (2x + 6x) gives 8x, and adding the constants (7 + 5) results in 12. Therefore, the new equation resulting from adding the two given equations together is 8x = 12.
