I used the Old Change New method and cross multipled
I multiplied $48.76 * 115% (100% + 15%) which equal to 5607.4
So I divided that 5607.4 by 100% and it equals to $56.074 or juat round it to $56
Check: $56 > $48.76 by 15% so the answer is $56 after 15% tip
Answer:
<em>The perimeter is c. 28 millimeters</em>
Step-by-step explanation:
<u>The Perimeter of a Square</u>
The perimeter of a square is the sum of all its side lengths. If the side length is L, then the perimeter is:
P = 4L
The diagonal of a square is the hypotenuse of a right triangle with both legs of length L.
Applying Pythagora's theorem, we find the length of the diagonal is:
We know the diagonal of a square is
We can find the side length L:
Simplifying:
L = 7 millimeters
Thus, the perimeter is:
P = 4*7 = 28
The perimeter is c. 28 millimeters
Answer:
point lies on circle
Step-by-step explanation:
Substitute the coordinates of the point into the left side of the equation and if equal to the right side then point lies on circle.
(4 - 1)² + (2 + 2)² = 3² + 4² = 9 + 16 = 25 = right side
Then point (4, 2 ) lies on the circle
Answer: 133.69 or 133.7
Step-by-step explanation:
Subtract 3x from 5x getting 2x so your new equation is: 2x-1/4=-5/4 then you add 1/4 to -5/4 getting : 2x=-1 the you divide both sides by 2 so x=-1/2<span>
