Let's solve this question by step by step.
Layout equation.
−104=−8(k+8)
Step 1: Simplify both sides of the equation.
−104=−8(k+8)
−104=(−8)(k)+(−8)(8)(Distribute)
−104=−8k+−64
−104=−8k−64
Step 2: Flip the equation.
−8k−64=−104
Step 3: Add 64 to both sides.
−8k−64+64=−104+64
−8k=−40
Step 4: Divide both sides by -8.
-8k/-8=-40/-8
The answer for this problem is k=5.
Answer: The area is approximately 314 ft^2
Step-by-step explanation:
Well if the diameter is 20 feet then the radius will be 10 because the radius is half the diameter, and to find the area of a circle, you use the formula
A=
where A is the area and pi times the radius squared.
We will represent pi by 3.14
A= 3.14* 10^2
A= 3.14 * 100
A = 314
Answer:
X = 25, Angles are 65 degrees

Answer:
$2326
Step-by-step explanation:
I have $1000 invested in a coin worth $43000. If the coin reaches $100000 how much will I have invested?
To solve the above question, we have:
$43,000 = $1000
$100,000 = x
Cross Multiply
43000 × x = 100,000 × 1000
x = 100000 × 1000/43000
x = $2325.5813953
Approximately = $2326
Therefore, If the coin reaches $100000 you would have invested $2326
