Answer:

40 miles per hour

Step-by-step explanation:

change hours and minutes to hours

12 minutes = 12 minutes * 1 hr/ 60 minutes = 12/60 hrs

12/60 = 1/5 = .2 hours

1 hours 12 minutes = 1.2 hours

48 miles in 1.2 hours

48/1.2 = 40 miles/hour

Determine if the statement is true or false The figures below are similar

artcher [175]

Answer:

True

Step-by-step explanation:

The polygons given have 5 sides, so the sum of their interior angles is (5-2) * 180 = 540. Next, there are 4 pairs of corresponding sides. Writing those sides as a, b, c, and d, for each pentagon, we can write

540 = a + b + c + d + missing angle

As is shown here, if a, b, c, and d are the same, 540 - (a+b+c+d) = missing angle is the same as well. Therefore, there are 5 corresponding angle pairs for the two polygons. Furthermore, because there are only 5 angles for each polygon, and because having all corresponding angles be equal makes polygons similar to each other, the polygons given are similar

Whats a equation for a linear function that passes through the point (3,7) and (0,13).

allsm [11]

Answer:

Step-by-step explanation:

First do your x2-x1/y2-y1 to find slope, which is 0-3/7-13 = -3/-6 = 1/2

Then plug into point slope form (choose either point)

(y-13) = 1/2(x-0)

(y-7) = 1/2(x-3)

Where e is enclosed by the planes z = 0 and z = x + y + 9 and by the cylinders x2 + y2 = 4 and x2 + y2 = 16?

katrin [286]

Best to use cylindrical coordinates. The volume (assuming that's what you're supposed to find) of the region is given by the triple integral

$\displaystyle\iiint_E\mathrm dV=\int_{\theta=0}^{\theta=2\pi}\int_{r=2}^{r=4}\int_{z=0}^{z=r(\cos\theta+\sin\theta)+9}r\,\mathrm dz\,\mathrm dr\,\mathrm d\theta$
$=\displaystyle\int_{\theta=0}^{\theta=2\pi}\int_{r=2}^{r=4}(r^2(\cos\theta+\sin\theta)+9r)\,\mathrm dr\,\mathrm d\theta$
$=108\pi$
