Which conversion factors can be used to find the number of hours in a week? Select all that apply.
Archy [21]

Answer:

3rd and 4th options are correct that is 24 hours per day and 7 days per week.

Step-by-step explanation:

We need to find the conversion factors that can be used to find number of hours in a week.

We know that,

Number of hours in a day = 24

and

Number of days in a week = 7

So, Number of hours in 7 days = 24 × 7 = 168.

Therefore, 3rd and 4th options are correct that is 24 hours per day and 7 days per week.

Y=-x+1 y=2/3x-4 please answer this!!!!
yawa3891 [41]

Answer:

(x, y) = (-15, -14)

Step-by-step explanation:

y = x+1

y = 2/3x - 4

Next, we will substitute the value of y (first equation) into the second equation.

x+1 = 2/3x - 4

1/3x + 1 = -4

1/3x = -5

x = -15

So, y = -14

Draw polygon abcdef in this coordinate plane, given its vertices a=(-2,-3), b=(0,-3), c=(0,1), d=(3,1), e=(3,3), f=(-2,3)
tiny-mole [99]

The polygon abcdef in the coordinate plane shown with area of 18 square units.

<h3>What is a regular polygon?</h3>

A polygon is a geometric figure with a finite number of sides in two dimensions. On the sides or edges of a polygon, straight-line segments are joined end to end to form a closed shape. The vertices, also known as corners, are the points where two line segments meet and form an angle.

We have vertices for the polygon:

a=(-2,-3), b=(0,-3), c=(0,1), d=(3,1), e=(3,3), f=(-2,3)

After marking the coordinates on the coordinate plane and connecting the lines, we will get a polygon.

We can find the area of the shape:

Area of the shape = 18 square units

Thus, the polygon abcdef in the coordinate plane shown with area of 18 square units.
