Step-by-step explanation:

First of all we need to know how odometer works. The change in odometer means the distance you have travelled.

Therefore:

112773-112352

=421 miles

Average, meaning you take the distance travelled divided by the gallons of gas used.

421/16

=26.3125

round up

≈26

Th temperature at 6 pm was 72f. This temperature was 8F less than 4pm. The temperature at 10am. Was 5F greater than the 4pm temp

Temp. at 6 pm. was 72...
that temp. was 8 less then at 4 pm....so at 4 pm, it was 72 + 8 = 80
the temp. at 10 am was 5 greater then at 4 pm.....so at 10 am, it was 80 + 5 = 85 F <===

Find the perimeter of the polygon with the vertices U(−2, 4), V(3, 4),U(−2, 4), V(3, 4), and W(3,−4)W(3,−4).

d1i1m1o1n [39]

Answer:

Perimeter = 22.434

Step-by-step explanation:

To find the perimeter we need to find the length of all three sides, and we do that by finding the distance between the points that form the sides:

The formula for the distance between two points is:

$d = \sqrt{(x_1 - x_2)^2 + (y_1 - y_2)^2}$

side UV:

$UV = \sqrt{(-2 - 3)^2 + (4 - 4)^2} = 5$

side VW:

$VW = \sqrt{(3 - 3)^2 + (4 - (-4))^2} = 8$

side UW:

$UW = \sqrt{(-2 - 3)^2 + (4 - (-4))^2} = 9.434$

So the perimeter is:

$P = UV + VW + UW$

$P = 5 + 8 + 9.434 = 22.434$
