For part A, use the Pythagorean Theorem.

a.) Since we see that the triangle is made up of two right triangles, simply subtract half the leg from the length of the hypotenuse.

10/2 = 5

13² - 5² = 169 - 25 = √144 = 12 centimeters cubed for the height.

b.) For this, we need to find the surface area of the prism. The surface area of a triangular prism can be found using the formula:

Surface area (SA) = 10(12) + (10 + 13 + 13)(20)

=120 + 660 = 780 cm²

1/2(32) = 32/2 = 16 are blonde

1/4(32) = 32/4 = 8 have black hair

1/4(32) = 32/4 = 8 have brown hair

Find the missing segment.

Bond [772]

Answer:

? = 7.

Step-by-step explanation:

The two triangles are similar because of the AA Theorem.

The larger triangle's side that is equal to 9 + 3 corresponds to the smaller triangle's side length of 9, while the larger triangle's 21 + ? side corresponds to the smaller triangle's 21 side. Now, we can set up a proportion!

$\frac{9}{9+3} =\frac{21}{21 + ?}$

$\frac{9}{12} =\frac{21}{? + 21}$

$\frac{3}{4} =\frac{21}{? + 21}$

$\frac{1}{4} =\frac{7}{? + 21}$

? + 21 = 7 * 4

? + 21 = 28

? = 28 - 21

? = 7

Hope this helps!

Applications: Sarah's Pet Store never has more than a combined total of 16 cats and dogs. She also never has more than 9 cats. W

ankoles [38]

The possible solution is 12 cats and 4 dogs in Sarah's store.

Let x represent the number of cats and y represent the number of dogs.

Since Sarah's Pet Store never has more than a combined total of 16 cats and dogs. Hence:

x + y ≤ 16

Also, She also never has more than 9 cats. Therefore:

x > 9

The solution to the inequality is graphed. From the graph, the possible solution is 12 cats and 4 dogs

A football team gained 5 yards and then last 7 yards. What real number represents the teams position relative to its original po

lana66690 [7]

Answer:

$\boxed{-2}}$

Step-by-step explanation:

Think of this situation as a number line in which the team starts at 0 yd.

Gaining yards is the positive direction and losing yards is negative.

Start at 0 yd and go 5 yd to the right. You are at +5.

Then go 7 yd left. You end up at -2.

+5 – 7 = -2

$\text{The real number that represents the team's position relative to its original position is $\boxed{\mathbf{-2}}$}$
