Solve similar triangles (basic)

Mathematics
1 answer:
fiasKO [112]2 years ago
4 0

Answer:

<em>T </em><em>=</em><em> </em><em>1</em><em>6</em>

Step-by-step explanation:

As triangles are similar

AB/DE = BC/EF = AC/DF

13.5/18 = 6/4 = 12/T

3/4 = 3/4 = 12/T

3/4 = 12/T

T = 12×4/3

T = 16

What is the reason for each step in the solution of the inequality?
Citrus2011 [14]

step 1: Given

step 2: Distributive Property

step 3: Combine Like terms

step 4: Subtraction Property of Order

step 5: Addition property of order

step 6: Division property of order

Step-by-step explanation:

We are given the inequality: -38-3(x+5)>6x-17

We need to match each step with the reasons.

The given steps are:

1.

−38−3(x+5)>6x−17

So, Reason for step 1: Given

2.

−38−3x−15>6x−17

So, Reason for step 2: Distributive Property

3.

−3x−53>6x−17

So, Reason for step 3: Combine Like terms

4.

−9x−53>−17

So, Reason for step 4: Subtraction Property of Order

5.

−9x>36

So, Reason for step 5: Addition property of order

6.

x<−4

So, Reason for step 6: Division property of order

The cost (c) to hire a dog trainer is varies directly with the amount of time (h) in hours spent training the dog.
NNADVOKAT [17]

Answer:

Part A) The proportional equation is c=55h

Part B) 8 hours of training

Step-by-step explanation:

we know that

A relationship between two variables, x, and y, represent a proportional variation if it can be expressed in the form y/x=k or y=kx

Let

c -----> the cost to hire a dog

h ----> the amount of time in hours

The linear equation is equal to

c=kh

Sue spent $660 on 12 hours of obedience training for her dog Muffin

Find the value of k (constant of proportionality)

k=y/x

substitute the values

k=660/12=55

therefore

The linear equation is

c=55h

For c=\$440

Find the value of h

substitute in the equation and solve for h

440=55h

h=440/55=8\ hours

On the right side we have st which is the same as s*t or s times t

We want to undo the multiplication that is happening to s, so we have to divide both sides by t

d = s*t

d/t = s*t/t ..... divide both sides by t

d/t = s

s = d/t

Answer: Choice A)
