Answer:
yes
Step-by-step explanation:
12*90=1080 so yes
there are 12 months in a year and if she pays 90$ each month the equation will be 12*90=1080
Answers:
121/11=11
23/3=23/3
85/5=17
37/83 0.44 x 100 = 44% ( to two decimal places) actual would be 44.57831325
Answer:
A = (1/2)Cr . . . or . . . A = C^2/(4π)
Step-by-step explanation:
The diagram shows the area of the circle being redrawn as a parallelogram with the length of it being half the circumference and the height of it being the radius of the circle.
The area of the parallelogram is the product of its length (C/2) and its height (r), so you can compute ...
A = (1/2)Cr
___
Given only the circumference, C = 2πr, you can find the value of r by dividing by its coefficient:
C/(2π) = r
Using this in the above formula, the area can be found from the circumference only as ...
A = (1/2)C·(C/(2π))
A = C^2/(4π)
If you would like to know the solutions to the quadratic equation, you can find this using the following steps:
3 * (x - 4)^2 = 75
3 * (x^2 - 8x + 16) = 75 /3
<span>x^2 - 8x + 16 = 25
</span>x^2 - 8x + 16 - 25 = 0
x^2 - 8x - 9 = 0
(x - 9) * (x + 1) = 0
1. x = 9
2. x = -1
The correct result would be <span>x = −1 and x = 9.</span>
