Rachel runs 3.2 miles each weekday and 1.5 miles each day of the weekend. How many miles will she have run in 6 weeks?

Mandarinka [93]

Rachel will have ran 114 miles in six weeks.

There's five weekdays in a week: (3.2 x 5) = 16 miles

There's two days in a weekend: (1.5 x 2) = 3 miles

16 [weekday] + 3 [weekend] = 19 miles [7-day week]

(19 x 6) = 114 miles

Hope this helps, please mark brainliest. Have an amazing rest of your day and stay safe! xx

Based on the graph, what is the perimeter of an octagon?

Ghella [55]

Answer:

The perimeter of the regular octagon is 104 units

Step-by-step explanation:

we know that

The segment LM is the length of one side of the octagon

we have the coordinates

L(-6,-2) and M(6,3)

step 1

Find the distance LM

the formula to calculate the distance between two points is equal to

$d=\sqrt{(y2-y1)^{2}+(x2-x1)^{2}}$

substitute the values

$d_L_M=\sqrt{(3+2)^{2}+(6+6)^{2}}$

$d_L_M=\sqrt{(5)^{2}+(12)^{2}}$

$d_L_M=\sqrt{169}$

$d_L_M=13\ units$

step 2

Find the perimeter

we know that

A regular octagon has eight equal sides

To find out the perimeter, multiply by 8 the length of the segment LM

$P=8(13)=104\ units$
