Mathematics

Answer:

Step-by-step explanation:

The exterior angles are out of the triangle at all times and it adds up to make 180 with anyone of the inside angle of the triangle.

The pair also rests on the same flat/straight line and that makes a pair.

Therefore we can say that it is formed by a linear pair/group with one of the interior/inside angles of the triangle.

So, the correct answer would be D.

200 kg of brass is melted down and cast into ornamental frogs, each weight 3/20kg. How many frogs are made?

Savatey [412]

Answer:

1,333 frogs

Step-by-step explanation:

okay so we know that mass remains conserved no matter where you are.

same here ^^

if the total mass of brass is 200 kg

the total mass of the new frogs formed from it when put together will be the same :)

and if there were n such frogs formed

we have,

total mass = n × mass of each frog

200 = n × 3/ 20

n = 4000/ 3

so it becomes something like 1,333.33

that is nearly 1,333 frogs can be made out of 200 kg of brass each weighing 3/ 20kg (the last ones a bit less to make upto 200kg)

What is the approximate area of the circle shown below?

bekas [8.4K]

Answer:

A. 804 cm²

Step-by-step explanation:

Formula :

$\boxed{A = \pi r^2}$

A = 3.14 × 16²

A = 3.14 × (16 × 16)

A = 3.14 × 256

A = 803.84 cm²

A = 804 cm² (rounded)

So, the approximate area of the shown below is 804 cm² (A)

Solve by factoring. x2 - 49 = 0

Gelneren [198K]

Remember
difference of 2 perfect squares
a^2-b^2=(a-b)(a+b)

(x)^2-(7)^2=(x-7)(x+7)

set to zero
x-7=0
x=7

x+7=0
x=-7

x=-7 or 7

Use ∆ABC to find the value of cos A.

Vinil7 [7]

Using the catchphrase SohCahToa, we can determine that the cosine ratio is equal to the length of the side adjacent to the angle over the length of the hypotenuse of the right triangle.

To find the cos∠A, we will look for side lengths BC and AB.

cosA = $\frac {9}{41}$

Since $\frac {9}{41}$ is already in it's simplest form, we can conclude that the cosine of ∠A is $\frac {9}{41}$ .

Hope this helps! :^)
