A rectangular room is 12 feet wider than its a long how many 1 ft.² tiles does it take to tile along the inside of the room let

Ludmilka [50]

Answer:

Number of of tiles will be $x^2+12x$ .

Step-by-step explanation:

Given:

let 'x' represent the length of the room.

Width is 12 feet wider than its length.

Width = $x+12$

Area of tiles = $1 ft^2$

We need to find number of tile along the inside of the room.

First we will find Area of room.

Area of room will be equal to length times width.

framing in equation form we get;

Area of room = $x(x+12)= x^2+12x$ sq. ft.

Now Number of Tiles will be equal to Area of room divided by Area of tile.

framing in equation form we get;

Number of Tiles = $\frac{x^2+12x}{1} = x^2+12x$

Hence Number of of tiles will be $x^2+12x$ .

Lily’s sister has a bag of skittles containing 3 yellow skittles, 4 red skittles, 5 green skittles, and 3 orange skittles. What

lisov135 [29]

Answer:

Read a bit so you can understand which one you want.

Percentage

15 skittles, 3 of the 15 are orange.

3 over 15, or 0.2 as a percentage.

So there is a 0.8% chance that he will NOT pick an orange skittle.

Fraction

15 skittles, 3 over 15.

3 over 15 can be 1 over 5.

So there is a 4 over 5 chance that he WONT grab an orange skittle, pretty good odds.

2. 40 cm^2

3. 14 cm^2

4 49 cm^2

Step-by-step explanation:

Area of triangle= 1/2(base)*(height)

Area of rectangle= (base)*(height)

1. 1/2(10)(4)=20

2. (8)(5)=40

3.1/2(4)(7)=14

4. (7)(7)=49

What is 3+0.5(4a+8)=9-2a is your solving for (a).

Nady [450]

Answer:

$a = 1/2$

Step-by-step explanation:

Step 1: Distribute

$3 + 0.5(4a + 8) = 9 - 2a$

$3 + (0.5 * 4a) + (0.5 * 8) = 9 - 2a$

$3 + 2a + 4 = 9 - 2a$

Step 2: Combine like terms

$(3 + 4) + 2a = 9 - 2a$

$7 + 2a = 9 - 2a$

Step 3: Subtract 7 from both sides

$7 + 2a - 7 = 9 - 2a - 7$

$2a = 2 - 2a$

Step 4: Add 2a to both sides

$2a + 2a = 2 - 2a + 2a$

$4a = 2$

Step 5: Divide both sides by 4

$4a / 4 = 2 / 4$

$a = 1/2$

Answer: $a = 1/2$

Describe how to transform the graph of f into the graph of g. f(x) = square root of quantity x minus nine. and g(x) = square roo

ruslelena [56]

Answer:

Translate the graph 14 units horizontally to the left by adding to the x-variable the constant 14.

Step-by-step explanation:

Translations of "c" units in the horizontal axis are obtained by adding or subtracting the constant value "c" to the variable x itself. When we want to translate the graph to the right, we subtract c, and when we want to move the graph horizontally to the left , we add c.

In this case, to go from the radicand (x-9) to the radicand (x+5), an addition of 14 units has to be performed, and such corresponds to a horizontal displacement to the left in 14 units.
