Answer: 300*0.73^x
Step-by-step explanation:
300 is the initial value and every time x goes up by 1, the value get multiplied by 0.73
when x=3
then the value would be 300*0.73*0.73*0.73 or 300*0.73^3
then for x amount of times the equation would be 300*(0.73 x times ) or 300*0.73^x
Answer:
More than half I think its based off of a 1-10% scale
Step-by-step explanation:
it's greater than 5%
Pythagorean Theorem is for triangles not circles.
The equation of a circle is (x - h)² + (y - k)² = radius² where (h, k) is the center.
Plug in your given information and simplify.
(x - (- 1))² + (y - 2)² = (3)²
(x + 1)² + (y - 2)² = 9 is your equation.
Answer:
Adult plate = 21 , child plate = 11
Step-by-step explanation:
number of adult plate = a , no of child plate = c
$487 = $19a + $8c (equation 1)
32 = a + c (equation 2)
Multiply equation 2 by 8 gets you:
256 = 8a + 8c (equation 3)
Solve equation 1 and equation 3 simultaneously:
487 = 19a + 8c (equation 1) minus
256 = 8a + 8c (equation 3) :
231 = 11a
a = 231/11
a= 21
Substitute a = 21 into equation 2 :
32 = 21 + c
c = 32 - 21
c = 11
So 21 adult plates and 11 child plates were sold.
