In a trapezoid the lengths of bases are 11 and 18. The lengths of legs are 3 and 7. The extensions of the legs meet at some poin

FrozenT [24]

Answer: The length of segments between this point and the vertices of greater base are $7\frac{5}{7}$ and 18.

Step-by-step explanation:

Let ABCD is the trapezoid, ( shown in below diagram)

In which AB is the greater base and AB = 18 DC= 11, AD= 3 and BC = 7

Let P is the point where The extended legs meet,

So, according to the question, we have to find out : AP and BP

In Δ APB and Δ DPC,

∠ DPC ≅ ∠APB ( reflexive)

∠ PDC ≅ ∠ PAB ( By alternative interior angle theorem)

And, ∠ PCD ≅ ∠ PBA ( By alternative interior angle theorem)

Therefore, By AAA similarity postulate,

$\triangle APB\sim \triangle D PC$

Let, DP =x

⇒ $\frac{3+x}{18} = \frac{x}{11}$

⇒ 33 +11x = 18x

⇒ x = 33/7= $4\frac{5}{7}$

Thus, PD= $4\frac{5}{7}$

But, AP= PD + DA

AP= $4\frac{5}{7}+3 =7\frac{5}{7}$

Now, let PC =y,

⇒ $\frac{7+y}{18} = \frac{y}{11}$

⇒ 77 + 11y = 18y

⇒ y = 77/7 = 11

Thus, PC= 11

But, PB= PC + CB

PB= 11+7 = 18

Answer:

The length of the shortest piece is $1\textrm{ ft}$ .

The length of the medium-sized piece is $3\textrm{ ft}$ .

The length of the longest piece is $7\textrm{ ft}$ .

Step-by-step explanation:

The five-step method is GUESS method.

Given:

Length of copper wire, $L=11\textrm{ ft}$

Length of longest piece is 6 feet longer than the shortest one.

Length of the medium-sized piece is 3 times the shortest one.

Unknown:

Length of longest, medium-sized and shortest pieces of wire.

Let the length of shortest piece be $x$ feet.

Therefore, the length of longest piece is equal to $6+x$ .

And, length of the medium-sized piece is equal to $3x$ .

Evaluate:

Sum of lengths of longest, medium-sized and shortest pieces of wire is equal to the total length of wire. So,

$6+x+x+3x=11\\5x+6=11\\5x=11-6\\5x=5\\x=\frac{5}{5}=1$

Substitute and Solve:

Now, we have, $x=1$ .

Substitute 1 for $x$ and solve for each sizes of wire pieces. This gives,

Length of shortest piece = $x=1\textrm{ ft}$

Length of medium-sized piece = $3x=3(1)=3\textrm{ ft}$

Length of longest piece = $6+x=6+1=7\textrm{ ft}$

Therefore, the lengths of shortest, medium-sized, and longest pieces are $1\textrm{ ft}$ , $3\textrm{ ft}$ and $7\textrm{ ft}$ respectively.

Question 2 of 20

nikklg [1K]

Given:

The function on the Input output table.

To find:

The range of the given function.

Solution:

We know that, range is the set of output values.

From the given table it is clear that, hours of training is the input variable and pay per month is the output value.

So, range of the given function is the set of pay per month.

Range = {1100, 1200, 1300, 1400, 1500, 1600, 1700}

Therefore, the correct option is A.
