T = total bill = 20 + 8.90 = $28.90
O = original bill

O * 1.18 = T
O * 1.18 = 28.90
O = 28.90 / 1.18
O = $24.49

The sum of the digits of a two-digit

Ann [662]

Answer:

45

Step-by-step explanation:

Let the unit place be ‘x'

Tenth place be y

The number is 10y+x

x+y = 9 (according to the condition) (1)

Digits are interchanged Unit place' y ‘& tenth place ‘ x'

New no is 10x +y

This is 9 more than the original number

10x+ y = 10y+x +9

10x-x+y-10y = 9

9x-9y= 9

x-y = 1 (dividing by 9) (2)

Adding the two equations

2x = 10

x= 5

Substituting the value of x in first equation

y = 4

The number is 45, the original number is 54 this is 9 more of the new number.

12. Find the radius of a circle with a<br> circumference of 457 centimeters.

irga5000 [103]

Step-by-step explanation:

$Circumference=d\pi\\Circumference=2r\pi$

Since we need to find the radius, then we will rearrange the second formula.

$Radius=\frac{C}{2\pi }$

$Radius=\frac{457}{2\pi }$

$Radius=\frac{457}{6.28}$

$Radius= 72.8 (rounded)$

So, the radius of a circle that has a circumference of 457 is about 72.8 cm
