Step-by-step explanation:

3.4 and -3.4 both have the same absolute value.

It appears that these days would be Tuesday and Friday based on the data you have provided.

Absolute Value

Absolute value is based on the numbers alone, and not the sign in front of them (negative or positive)

When considering absolute value, ignore positive and negative signs. Absolute value is indicated by terms inside of | | straight vertical lines

Example:

|3.4| = 3.4

|-3.4| = 3.4

Identify the coordinates of the point (3,-2), translated 5 units left and 6

kap26 [50]

Answer:

(- 2, 4 )

Step-by-step explanation:

A translation of 5 units left means subtract 5 from the original x- coordinate.

A translation of 6 units up means add 6 to the original y- coordinate.

Thus

(3, - 2 ) → (3- 5, - 2 + 6 ) → (- 2, 4 )

A tire on a toy car has a diameter of 8 cm if the toy car travels 12,560 cm approximately how many times does the tire rotate? U

Marina86 [1]

Answer:

The number of rotations completed by tire = 500.

Step-by-step explanation:

The diameter of the tire of toy car = 8 cm

Now, DIAMETER = 2 x RADIUS

So, radius of the tire = D/2 = 8/2 = 4 cm

Now, Circumference of the Circle = 2πr

= 2 x 3.14 x 4 = 25.12 cm

Now, $\textrm{Total number of rotations} = \frac{\textrm{Total Area covered}}{\textrm{Area covered in 1 rotation}}$

= $\frac{12,560}{25.12} = 500$

The number of rotations completed by circle = 500.
