Answer: 348in^2

Step-by-step explanation:

8 x 9 = 72

72 x 2 = 144in^2 (front and back)

8 x 6 = 48

48 x 2 = 96in^2 (sides)

9 x 6 = 54

54 x 2 = 108in^2 (top and bottom)

Total Surface area = 144 + 96 + 108 = 348in^2 (second option on picture)

ASAP On the coordinate plane below, quadrilaterals TRAP and HELP are similar to each other.

ipn [44]

Answer:

1 : 2

Step-by-step explanation:

Since the quadrilaterals are similar then the ratios of corresponding sides are equal, that is

$\frac{HP}{TP}$ = $\frac{2}{4}$ = $\frac{1}{2}$

Thus the ratio of perimeters is also 1 : 2

Find the coordinates of the point 7/10 of the way from A to B. a=(-3,-6) b=(12,4)

Artemon [7]

Answer:

The coordinates of $M$ are $x = \frac{15}{2}$ and $y = 1$ .

Step-by-step explanation:

Let be $A = (-3,-6)$ and $B = (12, 4)$ endpoints of segment AB and $M$ a point located 7/10 the way from A to B. Vectorially, we get this formula:

$\overrightarrow {AM} = \frac{7}{10}\cdot \overrightarrow {AB}$

$\vec M - \vec A = \frac{7}{10}\cdot (\vec B - \vec A)$

By Linear Algebra we get the location of $M$ :

$\vec M = \vec A + \frac{7}{10}\cdot (\vec B - \vec A)$

$\vec M = \vec A +\frac{7}{10}\cdot \vec B - \frac{7}{10}\cdot \vec A$

$\vec M = \frac{3}{10}\cdot \vec A + \frac{7}{10}\cdot \vec B$

If we know that $\vec A = (-3,-6)$ and $\vec B = (12, 4)$ , then:

$\vec M = \frac{3}{10}\cdot (-3,-6)+\frac{7}{10}\cdot (12,4)$

$\vec M = \left(-\frac{9}{10},-\frac{9}{5} \right)+\left(\frac{42}{5} ,\frac{14}{5} \right)$

$\vec M =\left(-\frac{9}{10}+\frac{42}{5} ,-\frac{9}{5}+\frac{14}{5} \right)$

$\vec M = \left(\frac{15}{2} ,1\right)$

The coordinates of $M$ are $x = \frac{15}{2}$ and $y = 1$ .

Wewaii [24]

Answer:

5,000 Meters

Step-by-step explanation:

Because it is a rectangle, you multiple the length and width, which would be 100 x 50; getting you 5,000 m.
