Answer:
$74.90
Step-by-step explanation:
If $70 is your original price, you would need to multiply it by 1.07, because that is 107%.
Since the original price is 100% of the price, and sales tax is another 7% of the price, you are multiplying the original price by 107%, again making $74.90.
Do you understand?
You have to use the distributive property for the numerator on both equations.
Answer:
Weight of a cone: W=13⋅π⋅r2⋅h⋅μD.
Step-by-step explanation:
Answer:Explanation: The formula for the equation of a circle is (x – h)2+ (y – k)2 = r2, where (h, k) represents the coordinates of the center of the circle, and r represents the radius of the circle. If a circle is tangent to the x-axis at (3,0), this means it touches the x-axis at that point.
Step-by-step explanation:
The correct answer is: x=9
4(1-x)+2=-3(x+1 )
-4x +3x = -3 -6
-x=-9
x=9
