Answer:
3.5 i think
Step-by-step explanation:
r=(3V
4π)⅓=(3·180
4·π)⅓≈3.50263
The final equation is (x-5)^2 + (y+4)^2 = 10^2.
Hopefully this'll help you!
The square of any number means to self-multiply. This means 5 is multiplied by itself, or 5x5. So, 5 x 5 = 25, and 8 x 8 = 64.
The sum of 25 + 64 = 89.
89 is the sum of the squares 5 and 8.
I hope this helps!
Yolanda's daily salary is $225
Step-by-step explanation:
The given is:
- Yolanda gave 20% of her daily salary to taxes
- She then put 10% of her remaining salary into her savings
- She is left with exactly $162
We need to find Yolanda's daily salary
Assume that Yolanda's daily salary is $x
∵ Yolanda gave 20% of her daily salary to taxes
∵ Yolanda's daily salary is $x
∴ The taxes = 20% × x
∵ 20% = = 0.2
∴ The taxes = 0.2 × x = 0.2 x
∴ The remaining of her salary = x - 0.2 x = 0.8 x
∵ She put 10% of her remaining salary into her savings
∴ The money in her saving = 10% × 0.8 x
∵ 10% = = 0.1
∴ The money in her saving = 0.1 × 0.8 x = 0.08 x
∴ The remaining of her salary = 0.8 x - 0.08 x = 0.72 x
∵ She is left with exactly $162
∴ The remaining of her salary = $162
∵ The remaining of her salary = 0.72 x
- Equate her remaining salary
∴ 0.72 x = 162
- Divide both sides by 0.72
∴ x = 225
Yolanda's daily salary is $225
