A rose garden is formed by joining rectangle and a semicircle, as shown below. The rectangle is 29 ft long and 21 ft wide. If th
Iteru [2.4K]

Answer:

The answer to your question is 116.53 ft

Step-by-step explanation:

Data

length = 29 ft

width = 21 ft

π = 3.14

Process

1.- Calculate perimeter of the rectangle and subtract 1 length

Perimeter of the rectangle = 2l + 2w - l

Perimeter of the rectangle = 2(29) + 2(21) - 29

                                            = 58 + 42 - 29

                                            = 71 ft

2.- Calculate the perimeter of a semicircle

Perimeter = 2πr/2 = πr

radius = r = 29/2

               = 14.5 ft

Perimeter = (3.14)(14.5)

                 = 45.53 ft

3.- Calculate the total length of the fence

fence = 45.53 + 71

          = 116.53 ft

A triangular course for a canoe race is marked with buoys. the first leg is 3/10 mi, the second leg is 1/2 mi, and the third leg
igomit [66]

Answer:

1 1/5 mi

Step-by-step explanation:

We need to add the three legs together

3/10 + 1/2 + 2/5

The common denominator is 10

3/10  =3/10

1/2 *5/5 = 5/10

2/5 *2/2 =4/10

3/10 + 5/10+4/10 = 12/10

10/10 = 10/10+2/10 = 1+2/10  = 1 1/5 mi

1. ∠ PRS and ∠ RPQ are right angles
Blababa [14]

Answer:

Given : PS = QR

            ∠PRS = ∠RPQ

            PR = PR (On the same base)

Proof / Reason :

∠PRS = ∠RPQ (R)

PS = QR          (H)

PR = PR           (S)

Therefore, Triangle PRS is congruent to Triangle RPQ

∠PSR = ∠RQP     By  C.P.C.T. ( Congruent Parts Of Congruent Triangles)

Thanks!

If on a scale 75 feet are represented by 45 inches, then a scale of 1/5 inch represents how many feet?
liberstina [14]

A scale of \frac{1}{5} inch represents \frac{1}{3} feet

<em><u>Solution:</u></em>

Given that,

On a scale drawing

45 inches represented = 75 feet

We have to find a scale of \frac{1}{5} inch in feet

Let us first find 1 inch in feet

From given,

45 inches = 75 feet

Therefore,

1 \text{ inches } = \frac{75}{45} \text{ feet }

Now find for \frac{1}{5} inch in feet

1 \times \frac{1}{5} \text{ inches } = \frac{75}{45} \times \frac{1}{5} \text{ feet }\\\\\frac{1}{5} \text{ inches } = \frac{75}{225} \text{ feet }\\\\\frac{1}{5} \text{ inches } = 0.33 \text{ feet }\\\\\frac{1}{5} \text{ inches } = \frac{1}{3} \text{ feet}

Thus a scale of \frac{1}{5} inch represents \frac{1}{3} feet
