Answer:

30 feet

Step-by-step explanation:

Let x be the length of the ladder. Then, x cos(60) = 15

If we divide both sides by cos(60), then x = 30 feet.

The length of ladder to be used by knight  will be of 30 feet

The angle of elevation is an angle that is formed between the horizontal line and the line of sight. If the line of sight is upward from the horizontal line, then the angle formed is an angle of elevation.

According to the question

The knight stands 15 feet from the base of the tower and the

angle of elevation to her window is 60 degrees.

Therefore, In figure

AB = Height of tower

CA = Distance between knight and tower  = 15 feet

BC = Length of the ladder

angle of elevation  = 60°

Now ,

Cos(60°) = [tex]\frac{Base}{Hypotenuse} = \frac{distance between knight and tower}{Length of the ladder } = \frac{15}{BC}[/tex]

[tex]\frac{1}{2} = \frac{15}{BC}[/tex]

BC = 30 feet

Length of the ladder  = 30 feet

Hence, the length of ladder will be used is 30 feet .

Answer:

cost of bread = $3.25

Cost per egg = $0.2

Step-by-step explanation:

Given the following :

Cost of a loaf of bread and 6 eggs = $4.45 - - (1)

Cost of a loaf of bread and a dozen eggs ( 12 eggs) = $5.65 - - - (2)

Let x = cost of bread and y = cost of egg

x + 6y = 4.45

x + 12y = 5.65

Subtract 1 from 2

6y - 12y = 4.45 - 5.65

-6y = - 1.2

y = $0.2

Hence,

From x + 6y = $4.45

Where y = $0.2

x + 6($0.2) = $4.45

x + $1.2 = $4.45

x = $4.45 - $1.2

x = $3. 25

Hence, cost of bread = $3.25

Cost per egg = $0.2

Answer:

1 solution

Step-by-step explanation:

-10 - 9z = -4 - 10z

Isolate z:

-9z + 10z = -4 + 10

z = 6

This is the only solution, so the equation has 1 solution.

Answer:

z = 6

1 solution

Step-by-step explanation:

–10 − 9z = –4 − 10z

Add 10z to each side

–10 − 9z+10z = –4 − 10z+10z

-10 +z = -4

Add 10 to each side

-10 +z +10 = -4+10

z = 6

Answer: D

Step-by-step explanation:

1/3) Let’s imagine a circle that passes through point R with the given center.

2/3) A 270 ángel takes up 3 on 4 of the circle.

3/3) D is the image of point R.

Clockwise rotation means rotating in the same way or direction as the hands of a clock move.

If point R is rotated about the center by 270 clockwise the image of point R is point D.

Clockwise rotation means rotating in the same way or direction as the hands of a clock move.

We have,

Point R is rotated clockwise about the center by 270 degrees.

We need to find the position of the R after the rotation.

i.e the image of the point R.

We know that the whole circle rotation is considered to have a 360-degree rotation.

270-degree rotation means it has rotated 3/4th of the circle.

So from the given figure, if the point R is rotated 3/4th of the figure in a clockwise direction the point R will be in the position of point D.

i.e the image of point R will be Point D.

Thus the image of point R is point D.

Given that:

A 15-foot log is cut into two pieces.

Longer piece is 1.5 feet shorter than twice the shorter piece.

Solution:

Let the length of shorter piece be x feet. So,

Length of longer piece = 2x-1.5 feet

Total length = x+(2x-1.5) feet

Now,

[tex]x+(2x-1.5)=15[/tex]

[tex]3x-1.5=15[/tex]

[tex]3x=15+1.5[/tex]

[tex]3x=16.5[/tex]

[tex]x=\dfrac{16.5}{3}[/tex]

[tex]x=5.5[/tex].

So, length of shorter piece is 5.5 feet.

[tex](2x-1.5)=2(5.5)-1.5[/tex]

[tex](2x-1.5)=11-1.5[/tex]

[tex](2x-1.5)=9.5[/tex]

So, length of longer piece is 9.5 feet.
