EleoNora [17]

Tim spends 500 minutes at the school.

Step-by-step explanation:

Given,

Time for lunch = 45 minutes

Time for study hall = 45 minutes

Total = 45+45 = 90 minutes

This represents 18% of the total minutes Tim spend at school.

Let,

x be the total minutes Tim spend at school.

18% of x = 90 minutes

\frac{18}{100}x=90\\\\0.18x=90

Dividing both sides by 0.18

\frac{0.18x}{0.18}=\frac{90}{0.18}\\x=500

Tim spends 500 minutes at the school.

Answer:

(x, y ) → (x + 6, y + 12 )

Step-by-step explanation:

We require to determine the horizontal and vertical shift to go from one of the points on the line to the corresponding point on the image

Consider point V with x- coordinate - 8 and y- coordinate - 2

The corresponding point is V'

with x- coordinate - 2 and y- coordinate 10

Thus V → V' is 6 units right in the horizontal direction and 12 units up in the vertical direction.

These are the same shifts for W → W'

Thus the translation rule is

(x, y ) → (x + 6, y + 12 )
