Answer:
$6.94
Step-by-step explanation:
Let's say that the cost of the hamburger without tax in 100%. Then the price with tax is 108% because there is an 8% tax. Therefore, $7.50 corresponds to 108%. if we divide 7.50 by 108 we get 0.0694444 or 1%. Finally, we multiply by 100 to get 100% or the cost without tax which is $6.94.
Answer:
Center: (9, 4)
Radius: 20
Explanation:
(x - 9)² + (y - 4)² = 400
The Circle Formula:
(x - h)² + (y - k)² = r²
where (h, k) is center points, r is radius
Rewrite the equation:
(x - 9)² + (y - 4)² = 20²
Identify following:
h = 9, k = 4, radius = 20
It’s would be 160 km since 160/80x60=120 min and 160/120x60=80min
Answer:u can estimate 246 to 200 and u can estimate 328 to 300
Step-by-step explanation:
add 34
Here the only limitation on the domain exists when the denominator is equal to zero, as division by zero has no meaning and is not "allowed" because of its meaninglessness. :)
Factor the denominator to find the excluded values of x...
3x^2+5x-12
3x^2+9x-4x-12
3x(x+3)-4(x+3)
(3x-4)(x+3)
So x CANNOT equal 4/3 or -3 (all other real values of x are part of the domain) so the domain is:
x=(-oo, -3),(-3, 4/3),(4/3, +oo)
