(image) The Figure Below Is An Isosceles Triangle Surmounted By A Semi-circle. Find The Area Of The Entire

Answers

Answer 1

Answer:

12.53

Step-by-step explanation:

∠BCA = (180°-40°)/2 = 70°

Laws of Sines: CA/sin 40° = AB/sin 70° = 5/sin 70°

CA = 5/sin 70° * sin 40° = 3.40

area of semicircle CA = (3.1416 * 1.70²) / 2 = 4.54

By Heron's Formula, area of triangle ABC:

1/4 √(a+b+c) (a+b-c) (b+c-a) (c+a-b) = 1/4 * √13.4*3.4*3.4*6.6

                                                          = 7.99

Entire region area = 4.54 + 7.99 = 12.53

How many cubic yards of concrete are in a light pole caisson having a diameter of 24 inches and a
depth of 6 feet?
a. 2.09
b. 1.4
c. .7
d. 18.9

Answers

Answer:

C. 0.7 yd³

Step-by-step explanation:

Find the volume of cylinder:

V = πr²h

Convert the dimensions into yards:

d = 24 inches = 24/36 yards = 2/3 yards ⇒ r = 1/2d = 1/2*2/3 = 1/3 yardsh = 6 feet = 6/3 yards = 2 yards

Find the volume by substituting the values:

V = 3.14*(1/3)²*2 = 0.69777 ≈ 0.7 yd³

Answer:

Step-by-step explanation:

The legs of the right triangles are drawn along the grid lines. You can count the grid lines to see how long they are. Use the given formula to find the square of the hypotenuse, then take the square root. The hypotenuse of each triangle is the straight-line distance between its end points.

It should be no surprise that 3^2 +4^2 is more than 3^2 +3^2, so the length from B to C will be longer than from A to C.

$29.99 x 0.2 = 5.998

$29.99 - 5.998 = $23.99

Answer: $23.992
Explanation: Since there is a 20% discount, the coat costs 80% of the original.
As such, 29.99 * 80%= 23.992

Right now Seth's age is 4/5 the age of his brother Eric. Twenty-one years ago, Eric was twice as old as Seth. What are their ages now?

Answers

Answer:

          Present Time                                                                

Let X= Eric's age                                                            (4/5)X= Seth's age

Question:  What are their ages now?________________________________________________________________________

                                             Past (21 years ago)

X-21 =Eric's age                                                                (4/5)X-21=Seth's age

2*[4/5(X-21]=Eric's age

Therefore, X-21= 2*[4/5(X)-21]=Eric's age           Substitution

_______________________________________________________________________

X-21= 8/5 X  - 42         Solve for "X" by adding 42 to both sides.

X-21+42=(8/5) X

X+21 = (8/5)X              Subtract "X" from both sides.

21=(3/5)X                    Multiply both sides of equation by reciprocal of (3/5), which is 5/3

21*(5/3)= X                  Finish the problem to find value of "X," which is Eric's age.  

                                   Then find  4/5 (X)= Seth's age  

Seth age = 4/5 × Eric's age

seth age = x

eric age = y

x = 4y/5 .....eqa 1

2(x-21) = y-21 ......eqa 2

2(4y/5 - 21) = y-21

8y/5 - 42 = y -21

8y/5 - y = 21

1.6 y - y = 21

0.6 y = 21

y = 35 years Eric's age

x = 28 years Seth's age

Expand 2(q+3) please

Answers

Answer:

2q + 6

Step-by-step explanation:

Expand the expression with the help of distributive property.

2(q + 3)=> (2 x q) + (2 x 3)=> 2q + 6

Hence, the expanded expression is 2q + 6.

Answer:

  2q +6

Step-by-step explanation:

The distributive property is used for this purpose. The factor outside parentheses (2) multiplies each of the terms inside parentheses (q, 3).

  2(q +3) = 2·q +2·3 = 2q +6

_____

Additional comment

It might help to think of the parentheses as a "bag" containing one "q" and 3 tokens. The number outside parentheses tells you how many "bags" you have. Expanding the expression is equivalent to dumping out the bags and describing the total contents:

  2(q +3) = (q +3) +(q +3) . . . . multiplication is the same as repeated addition

  = (q +q) +(3 +3)

  = 2q +6
