Bryan purchased two triangular wall shelves. The sides of each shelf are 8 inches, 10 inches, and 12 inches. He's trying to build a similar, larger triangular shelf to hang between the smaller ones. Which of the dimensions can Bryan use for the larger shelf so that it is similar to the ones he purchased? Justify why the three triangles are similar.A) 4 inches, 5 inches, and 6 inches; All of the side lengths of the smaller triangles have been multiplied by 1/2 which guarantees side-side-side similarity . B) 16 inches, 20 inches, and 24 inches; All of the side lengths of the smaller triangles have been multiplied by 2, which guarantees side-side-side similarity.

I need help with the answers please....I have no idea how to do this and I'm already behind

Answers

Remember alternative exterior angles are congruent... that means for example 12 that the angles are congruent

Also, interior angles are congruent... that means for example 17 the angles are congruent (also 19)

And, vertical angles are also congruent... that means for example in 18 the angles are congruent...

Consecutive angles also are congruent... that means 14

Corresponding angles are also congruent.. that means for example 13

Any other ones that I didn't exactly list... if they look like the ones I DID list then they go under that definition...

Hope this helps :)

A rectangular field is 80 meters wide and 125 meters long.Give the length and width of another rectangular field that has the same perimeter but a smaller area.

Answers

Perimeter of the rectangle is 2*(80+125)=410
The rectangle having the biggest area given the same perimeter is a square. So we need to go "the other way" -- find the rectangle with larger side ratio. 200 m and 5 m is a good example.

The area of the first rectangle: $80 m * 125 m =10000 m^2$
The area of the second rectangle : $200 m * 5 m = 1000 m^2$ (10 times smaller).

A lake in East Texas was stocked with 3,000 trout in the year 2000. The number of fish in the lake is modeled by f(x) = 3000 + 100x, where x represents the number of years after 2000 until 2016. Which of the following is the most reasonable domain for the function?

Answers

The domain of a function is the set of input values the function can take.

The reasonable domain of the function is [0,16]

From the question, we understand that x represents the number of years after 2000 until 2016.

In 2000, the value of x is 0
In 2016, the value of x is 16

Hence, the reasonable domain of the function is [0,16]

Answers

Factor in "x" the expression:

$ax+5x-4=10\n \n (a+5)x-4=10\n \n (a+5)x=10+4\n \n (a+5)x=14\n \n \boxed{x=(14)/(a+5)}$

What is the value of the variable?

19b = 38

Answers

The answer is 2. You divide 19 to sides of the equation, so you will get b=38/19, therefore your final answer is 2.

19b = 38

b = 2

Suppose you are determining the growth rate of two species of plants. Species A is 12 cm tall and grows 2 cm per month. Species B is 10 cm tall and grows 3 cm per month. Which system of equations models the height of each species H(m) as a function of months m.H(m ) = 2 + 12m
H(m ) = 3 + 10m

H(m ) = 2 + 12m
H(m ) = 10 + 3m

H(m ) = 12 + 2m
H(m ) = 3 + 10m

H(m ) = 12 + 2m
H(m ) = 10 + 3m

Answers

Answer:

The equations for the growth of two type of species are

H(m) = 12 + 2m

H(m) = 10 + 3m

Step-by-step explanation:

As given

The growth rate of two species of plants.

Species A is 12 cm tall and grows 2 cm per month.

The height of each species is represented by H(m) as a function of months m.

Than the equation becomes

H(m) = 12 + 2m

As given

Species B is 10 cm tall and grows 3 cm per month.

Than the equation becomes

H(m) = 10 + 3m

Than the equations for the growth of two type of species are

H(m) = 12 + 2m

H(m) = 10 + 3m

H(m) = 12 + 2m
H(m) = 10 + 3m
