5. Becca wants to edge her hexagonal garden

with brick. All sides are equal. The brick costs

$6 per yard. What is the perimeter of the

garden? How much will it cost to buy the

edging she needs?

Answers

Answer:

[tex](a)\ Perimeter = 6l[/tex]

[tex](b)\ Cost = \$36l[/tex]

Step-by-step explanation:

Given

[tex]l \to sides[/tex]

Solving (a): The perimeter

The shape has 6 sides; since the sides are equal, the perimeter is:

[tex]Perimeter = 6 * l[/tex]

[tex]Perimeter = 6l[/tex]

Solving (b): Cost of fencing

We have:

[tex]Unit\ cost = \$6/yd[/tex]

So, the cost is:

[tex]Cost = Unit\ cost * Perimeter[/tex]

[tex]Cost = \$6/yd * 6l[/tex]

[tex]Cost = \$36l[/tex]

To get the actual answer, substitute the length of one side of the hexagonal in the calculated expressions

Answer: P = 166 units

Step-by-step explanation: Each point on the triangle has lines that are tangent to the circle in the triangle, meaning that those lines form a 90° angle to the middle point in the circle. There is also a rule that states if there are tangent lines coming from the points and if the points have at least one given side length, the other side will have the same side length. So if one side on point D is 41, then the other side connected to the point is 41. I added up all of the side lengths; 41 + 41 + 30 + 30 + 12 +12 = 166 units.

Points A, B, C, and D are the vertices of a square. Points E and F are the center of two congruent semicircles that are tangent to each other at point G. Which value is closest to the area of the shaded regions? ​

Answers

Answer:

8 sq units

Step-by-step explanation:

to find the area of shaded region:

area of square minus sum of areas of each semi-circle

A(square) = 6² = 36

A (semi-circle) = πr²/2

= π3²/2

= 4.5π

Since there are two semi-circles, that makes one complete circle with an area of 9π

A(circle) ≈ 28 sq units

36-28 = 8 sq units

using the triangle 45o -45o -90o theorem solve this triangle. please​

Answers

Answer:

The length of the leg is 11 units.

Step-by-step explanation:

The triangle 45 - 45 - 90 theorem states that the length of the hypotenuse is [tex]\sqrt{2}[/tex] times of the length of any of the legs. Hence, we get the following expression:

[tex]h = \sqrt{2} \cdot l[/tex] (1)

Where:

[tex]l[/tex] - Length of the leg, in units.

[tex]h[/tex] - Hypotenuse, in units.

If we know that [tex]h = 11\sqrt{2}[/tex], then the length of the leg is:

[tex]l = \frac{h}{\sqrt{2}}[/tex]

[tex]l = 11[/tex]

The length of the leg is 11 units.

Solve 5x + 17 = 4(3x - 1) x = -3 x = -3 Infinitely many solutions Infinitely many solutions No solutions No solutions x = 3

Answers

Answer:

3 =x

Step-by-step explanation:

5x + 17 = 4(3x - 1)

Distribute

5x+17 = 12x -4

Subtract 5x from each side

5x+17-5x = 12x-4-5x

17 = 7x-4

Add 4 to each side

17+4 = 7x-4+4

21 = 7x

Divide by 7

21/7 = 7x/7

3 =x

Answer:

x = 3

Step-by-step explanation:

5x + 17 = 4(3x - 1)

Distribute on the right side.

5x + 17 = 12x - 4

Subtract 12x from both sides. Subtract 17 from both sides.

-7x = -21

Divide both sides by -7.

x = 3

A cube block has sides 8cm long. A cylindrical hole of radius 3.6 is drilled through the block. Find the volume of the block that remained

Answers

Answer:

186.45 cm^3

Step-by-step explanation:

Given data

Side lenght of cube block= 8cm

Radius of cylindrical hole= 3.6cm

Volume of entire Shape= l^3

Volume of entire Shape= 8*8*8

Volume of entire block= 512cm^3

Volume of cylindrical hole= πr^2h

Volume of cylindrical hole= 3.14*3.6^2*8

Volume of cylindrical hole= 3.14*12.96*8

Volume of cylindrical hole= 325.55cm^3

Hence the volume of the block

=volume of entire shape- volume of cylinder

=512-325.55

=186.45 cm^3

Could you help ? It says “ a nursery plants a new tree and attaches a guy wire to help support the tree while it’s roots take hold. An eight foot wire is attached to the tree and to a stake in the ground the angle of elevation of the connection with the tree is 42 degrees . Find the nearest tenth of a foot, the height of the connection point on the tree” .

Answers

Answer:

5.4'

Step-by-step explanation:

See diagram attached.

The 8' wire is the hypotenuse of the triangle, with a base angle of 42°.

Hence the height is the length of the hypotenuse multiplied by sin(42°)

H = 8sin(42°) = 8 *0.6691 = 5.353'
