<u>Answer:</u>

8.94 inches or $8\frac { 1 5 } { 1 6 }$ inches

<u>Step-by-step explanation:</u>

We know that the current height of the photo is $3\frac{1}{4}$ inches and the customer wants it to be enlarged by a factor of $2\frac{3}{4}$ its current height.

$3\frac { 1 } { 4 } = 3.25$

$2 \frac { 3 } { 4 } = 2.75$

To find the enlarged height, we will multiply the scale factor with the photo's current height.

Enlarged height = $3.25 \times 2.75 = 8.94 inches or [tex] 8\frac { 1 5 } { 1 6 }$ inches

NemiM [27]

Answer:

The height of the statue is 21.4 feet

Step-by-step explanation:

We are given

A person is standing 50 ft from a statue

The person looks up at an angle of elevation of 16 degree when staring at the top of the statue

hen the person looks down at an angle of depression of 8 degree when staring at the base of the statue

Firstly, we will draw diagram

In triangle ABF:

FC=50

we can use trig formula

$tan(16)=\frac{y}{50}$

$y=50tan(16)$

$y=14.33727ft$

now, we can find x

In triangle DEF:

we can use trig formula

$tan(8)=\frac{x}{50}$

$x=50tan(8)$

$x=7.0270ft$

we can see that

height of statue =x+y

so, the height of statue is

$=14.33727+7.0270$

$=21.4ft$

From a height of 50 meters above sea level on a cliff, two ships are sighted due west. The angles of depression are 61° and 28°.

Olenka [21]

Answer:

The ships are 66 meters apart.

Step-by-step explanation:

For the sake of convenience, let us label ships A and B

As shown in the figure, the distances to the ships from right triangles.

The distance to the ship A is $d_1$ and it is given by

$tan (61^o)= \dfrac{50}{d_1}$

$d_1=\dfrac{50}{tan (61^o)}$

$\boxed{d_1= 27.71m}$

And the distance to the ship B is $d_2$ and is given by

$tan (28^o)= \dfrac{50}{d_2}$

$d_2=\dfrac{50}{tan (28^o)}$

$\boxed{ d_2=94.04m}$

Therefore, the distance $d$ between the ships A and B is

$d= d_2-d_1=94.04-27.7\\\\\boxed{d=66m}$

In other words, the ships are 66 meters apart.

Perform the indicated operation 5 1/6 - 2 2/3

goldenfox [79]

Answer:

2½

Step-by-step explanation:

First find the Least Common Denominator [LCD], which is 6, then convert 5⅙:

5⅙ → 4 7⁄6

$5 \frac{1}{6} - 2 \frac{2}{3} = 4 \frac{7}{6} - 2 \frac{4}{6} = 2 \frac{3}{6} = 2 \frac{1}{2}$

You see, we regrouped 1 from 5⅙ to make sure that the top mixed number had a higher value than the bottom mixed number, so it is much easier to work with.

I am joyous to assist you anytime.
