Q 1: 1/9 · (1/2)³

Q 2: 1/8 · (1/3)²

1/72 and 1/81

Step-by-step explanation:

Using the order of operations (PEMDAS):

Question 1:

You solve the exponent first: 1/9 * 1/8

Multiply: 1/72 ( repeating)

Question 2:

You solve the exponent first: 1/9 * 1/9

Multiply: 1/81 (0.0123456...)

dilation scale factor 2: starting with δabc, draw the dilation image of the triangle with a center at the origin and a scale factor of two. notice that every coordinate of the original triangle has been multiplied by the scale factor (x2). dilation with scale factor 2, multiply by 2.

1,407.5 hours

step-by-step explanation:

we first convert all the time to hours and then sum them up.

there are 24 hours in 1 day, in 58 days, there are 24 x 58 = 1,392 hours.

there are 60 minutes in 1 hour, thus, 30 minutes will be equivalent to 30 / 60 = 0.5 hours.

therefore, the number of hours it will take mercury to complete a full rotation is 1,392 + 15 + 0.5 = 1,407.5 hours
