The area of a square is calculated by squaring the side length (A = s²). Consequently, 30 = s². Taking the square root gives us s = √30. A calculator shows that √30 is approximately 5.48, or through estimation, we can see that √25 < √30 < √36, suggesting that √30 falls between 5 and 6.
Zoe incurred $18.60 in tips and sales tax for her meal. The rate of sales tax stands at 11% while her tip amounted to 20%. (The tip does not include sales tax, and it is calculated on the dinner's price before tax.)
From the information provided, it's evident that both the tip and sales tax apply solely on the dinner cost. Thus, we have:-
Sales Tax = 11% of dinner cost
Tip = 20% of dinner cost
And Sales Tax + Tip = $18.60
Therefore, (20+11)% of dinner cost = 18.60
31% of dinner cost = 18.60
0.31 * dinner cost = 18.60
dinner cost = 18.60/0.31 = 60
Thus, Zoe's dinner cost was $60.
65^2-16^2=63^2, which means the answer is 63.
Answer:
First, we must calculate the slope
m=Y2-Y1/X2-X1
= 9 - (-6) / 12 - (-8)
= 15/20
= 3/4
Therefore, the equation with the slope of 3/4 is Y=3/4x
