Answer:

10 sheep

Step-by-step explanation:

First, we have to determine the area of the circular pen.

Area of a circle = [tex]\pi[/tex][tex]r^{2}[/tex]

But,

Circumference of a circle = 2[tex]\pi[/tex]r

So that,

77.5 = 2 x 3.14 x r

77.5 = 6.28r

r = 12.34

Radius of the pen is 12.34 feet.

Thus,

Area of the pen = [tex]\pi[/tex][tex]r^{2}[/tex]

                          = 3.14 x [tex](12.34)^{2}[/tex]

                    = 478.15

Area of the pen = 478.15 square feet

Number of sheep that can be safely kept in the pen = [tex]\frac{478.15}{45}[/tex]

                                           = 10.63

The number of sheep that can be safely kept in the pen is 10.

Answer:

1. h = 11 cm

2. d = 220 km

Step-by-step explanation:

1. A = 1/2bh

Where,

A = 66 cm²

b = 12 cm

A = 1/2bh

66 = 1/2 * 12 * h

66 = 6h

h = 66/6

h = 11 cm

2. s = d/t

Where,

s = 110 km/h

t = 2h

s = d/t

110 = d/2

Cross multiply

110 * 2 = d

d = 220 km

Answer:

16.8 in

Step-by-step explanation:

Given data

DIstance= 14 in

time= 2.5 hours

Speed= 14/2.5

Speed= 5.6 in per hour

Hence for 3 hours

Distance= speed*time

Distance= 5.6*3

Distance= 16.8 in

Answer:

x ≈ 21.7

I rounded to the nearest tenth because the values are given in tenths. The first few digits of x are below if you are rounding to something else, as the image is cut out.

Step-by-step explanation:

(It will not let me post, so I've attached a screenshot of my explanation:)

The value of x is  21.7 unit to the nearest tenth

Equations using trigonometric functions that hold true for all possible values of the variables are known as trigonometric identities.

Given:

The triangle is a right-angled triangle.

Then, cosx = Adjacent leg/ Hypotenuse

Cos37° = 17.3 / x

x = 17.3/ Cos37°

x = 17.3 / 0.7986.

x = 21.67 unit.

Therefore, the value of x is 21.67 unit.

Answer:

The graph is attached.

Step-by-step explanation:

The open circle is because the inequality sign is >. If the sign is > or <, the circle is plotted open. If the sign is [tex]\geq[/tex] or [tex]\leq[/tex], the circle is plotted closed.

The sign is greater than, so the arrow is pointed to the right (where the numbers are going up).

The circle is plotted between 12 and 14 because that is point 13, like the inequality says.
