The total bill that would be paid by Jan is equal to $43.125.

Given the following data:

Cost of Jan’s dinner = $18.50.

Cost of brother’s dinner = $19.00.

Tip = 15%

To determine the total bill that would be paid by Jan:

First of all, we would calculate the total cost of their dinner as follows:

$Total\;cost = 18.50 + 19.00$

Total cost = $37.50

Next, we would calculate the tip cost for the total cost of their dinner:

$Tip\;cost = \frac{15}{100} \times 37.5\\\\Tip\;cost =0.15\times 37.5$

Tip cost = $5.625

For the total bill:

$Total\;bill = Total\;cost + Tip\;cost\\\\Total\;bill = 37.5 + 5.625$

Total bill = $43.125.

Which of the following descriptions represents the transformation shown in the image

Viktor [21]

Answer: A. 270° rotation, 3 units left, and 2 units up

Step-by-step explanation:

C = (1, 1) D = (3, 3) E = (2, -2)

270° rotation counterclockwise means (x, y) = (y, -x)

new C = (1, -1) new D = (3, -3) new E = (-2, -2)

3 units left means subtract 3 from the x-coordinate

newer C =( -2, -1) newer D = (0, -3) newer E = (-5, -2)

2 units up means add 2 to the y-coordinate

C' = (-2, 1) D' = (0, -1) E' = (-5, 0)

Since the first option worked, there is no need to check the other options.

Answer:

Step-by-step explanation:

The maximum value of the sin function is at $\dfrac{\pi}{2}$ , when sin is equal to 1. Since you need to multiply pi/12 by 6 to get to pi/2, the maximum amount of people will be at the square after 6 hours. Hope this helps!
