The height of a building is 1383 feet. How long would it take for an object to fall from the top?

Answer:

Yes, one inch is a twlefth of a ft which is a porportion of a feet

Step-by-step explanation:

Step-by-step explanation:

1. -10b+b=-9

It is like you are doing this:

-10+1=-9

5. 5k+7k=12k

5+7=12

3. 1+5v+v= 1+6v

Like: 5+1

2.-x-3x=-4x

Like:-3-1=4 (both are negative numbers and you just add the second one)

4.-7n-7-8+10n=3n-15

You are doing this with n:

10-7=3 and this with numbers:

-7-8=-15 (both negative again)

6.a-2+1+4a= 5a-1

Like this: 4+1=5 and -2+1=-1

7. 8(x+10)= 8*x+8*10= 8x +80

8. 8(1+6p)= 8*1+8*6p= 8+48p

9.-5(-7+7n)= 35-35n ( when you * negative and positive numbers you get negative result and when you * negative and negative numbers you get positive result)

10.-(9m+7)= -9m-7 ( when you have - before () every number changes its sign).

Sorry for messy writing... Hope this helps.

Answer:

14

Step-by-step explanation:

because the sum of the 2 smaller side have to add up to greater than the larger side

x+4 > 17

x > 13

14 is the next biggest whole number

Answer:

81.12 cm²

Step-by-step explanation:

The area for a semicircle can be figured with this formula: (πr²)/2. The triangle's area formula is bh/2.

(3.14 * 4²)/2 + (14 * 8)/2 (Work the operations in parentheses first.)

(3.14 * 16)/2 + 112/2

50.24/2 + 112/2 (Divide 50.24 by 2. Do the same for 112.)

25.12 + 56 (Add 25.12 & 56.)

81.12 cm²

The area of the figure is 81.12 cm².

Answer: A

Step-by-step explanation:

Answer:

5

Step-by-step explanation:

The given two triangles are similar , therefore ,

⇒ 5x /20 = 45/36

⇒ x/4 = 5/4

⇒ x = 5/4 × 4

⇒ x = 5

Hence the value of x is 5.

Answer:

50-50 on both because there 3 even and 3 odd numbers

Answer:

50% chance of either or 1/2

Step-by-step explanation:

50% of either

Look a die has 12 sides

6 numbers are odd and the other 6 even

If you randomly roll a die you will have 6/12 chances of landing on a even number and a 6/12 chance of landing on a odd number

now 6/12 can be simplified to 1/2 which is 50%

Hope that helps!

Answer:

33232.92

Step-by-step explanation:

Answer:

Area = 346.2yd²

Perimeter = 72.1yd

Step-by-step explanation:

AREA

Split it into three shapes: (1) the semi-circle, (2) the triangle, and (3) the rectangle. Find the area of each and then add them together for the area of the whole shape.

Area₁ = πr² = (6²)π = 36π = 113.1 yd²

Area₂ = (1/2)bh = (1/2)(11.3)(14) = 79.1 yd²

Area₃ = lw = (11)(14) = 154 yd²

154 + 79.1 + 113.1=346.2yd²

PERIMETER

The perimeter consists of the length of the curve on the semi-circle, the top , the right side, the bottom, and the slanted line.

length of the curve on the semi-circle = half the cicumference of circle with radius 6 = (2π(6))/2 = 6π = 18.8

the top = 22.3

the right side = 14

the bottom = 11

the slanted line = the hypotenuse of triangle(2) - the diameter of circle(1) = (√(11.3²+14²))-12= (√(323.69))-12=18-12=6

18.8+22.3+14+11+6=72.1yd

Answer:

Slope=-1.8, X=-0.5, y=1.9

Equation is y^2-y^1=m(x^2-x^1).

Y-1.9=-1.8(X-(-0.5))

Y-1.9=-1.8x+0.90

Add 1.9 on both sides.

Y= -1.8x+1.

I hope this helps you.

Answer:

106.028752

Step-by-step explanation:

First, find the circumference which is 2 pi r.

2pi(45), 90pi, 282.743339

135 out of 360 degrees is 135/360 or 3/8

and 3/8 out of 282.743339 is 106.028752

Answer:

The total cost of the new carpeting is $ 1,055.43.

Step-by-step explanation:

Since I decide that I want new carpeting in my bedroom that measures 12 feet 6 inches wide by 15 feet 9 inches long, and the price of the carpet and the underlying pad is $ 3.49 per square foot, and I decide to upgrade to the deluxe underlying pad that costs an additional $ 0.62 per square foot, and the fee for installation is a flat fee of $ 180, to determine what is the total cost, including sales tax of 6.7%, of the carpet, pad, and installation, the following calculations must be performed:

1 inch = 0.08333 feet

6 inches = 0.08333 x 6 = 0.5

9 inches = 0.08333 x 9 = 0.75

12.5 x 15.75 = Bedroom area

196,875 square feet = Bedroom area

((196.875 x (3.49 + 0.62)) + 180) x 1.067 = Total cost

((196,875 x 4.11) + 180) x 1,067 = Total cost

(809.15625 + 180) x 1.067 = Total cost

989.15625 x 1.067 = Total cost

1,055,429 = Total cost

Therefore, the total cost of the new carpeting is $ 1,055.43.

Answer:

[tex]x = 19[/tex]

[tex]y = 22.5[/tex]

Step-by-step explanation:

[tex]5y + 3y = 180[/tex]

[tex]8y = 180[/tex]

[tex]y = 22.5[/tex]

[tex]6x + 13 + 4x - 3 = 180[/tex]

[tex]10x - 10 = 180[/tex]

[tex]10x = 190[/tex]
