You want to tile a 10 foot square floor with tiles that are twice as long as they are wide. determine how many tiles you need to cover the floor when the tile length is 2 feet

Answers

To cover a floor with an area of 10 square foot, 5 tiles is needed.

Area is the amount of space enclosed by a two-dimensional figure.

If the tile is 2 feet long and twice as long as they are wide, suppose that the tile is a rectangle, then the area of each tile will be:

Area of tile = l x w

where l = 2 feet

w = 1 foot

Area of tile = 2feet(1 foot)

Area of tile = 2 ft^2

To determine how many tiles are needed to cover a 10 foot square floor, divide the area of the floor with the area of each tile.

# of tiles = Area of floor/Area of each tile

# of tiles = 10 ft^2/2ft^2

# of tiles = 5

Find the equation of the line that passes through the following points. Write the equation in slope-intercept form.
(-4.-8) and (-8, -9)

Answers

Answer:

The equation in the slope-intercept form will be:

y  = 1/4x - 7

Step-by-step explanation:

Given the points

(-4.-8) (-8, -9)

[tex]\mathrm{Slope}=\frac{y_2-y_1}{x_2-x_1}[/tex]

[tex]\left(x_1,\:y_1\right)=\left(-4,\:-8\right),\:\left(x_2,\:y_2\right)=\left(-8,\:-9\right)[/tex]

[tex]m=\frac{-9-\left(-8\right)}{-8-\left(-4\right)}[/tex]

[tex]m=\frac{1}{4}[/tex]

We know that the slope-intercept of line equation is

[tex]y=mx+b[/tex]

where m is the slope and b is the y-intercept

substituting m = 1/4 and the point (-4, -8) to find the y-intercept 'b'

y = mx+b

-8 = 1/4(-4)+b

-8 = -1 + b

b = -8+1

b = -7

so the y-intercept = b = -7

substituting m = 1/4 and b = -7 in the slope-intercept form of line equation

y = mx+b

y  = 1/4x + (-7)

y  = 1/4x - 7

Thus, the the equation in slope-intercept form will be:

y  = 1/4x - 7

The answer is C.

Step-by-step explanation:

In order to find the x-intercept and y-intercept, you have to substitute 0 into each expression :

[tex]let \: x = 0[/tex]

[tex]0 - 3y = 6[/tex]

[tex] - 3y = 6[/tex]

[tex]y = 6 \div ( - 3)[/tex]

[tex]y = - 2[/tex]

[tex]let \: y = 0[/tex]

[tex]2x - 0 = 6[/tex]

[tex]2x = 6[/tex]

[tex]x = 6 \div 2[/tex]

[tex]x = 3[/tex]

Given that the x-intercept is 3 and y-intercept is -2. By looking at the picture, graph C fits the coordinates, (3,0) and (0,-2).

Which ratio is equivalent to the ratio 20 to 35? 5 to 7 7 to 5 8 to 14 14 to 8

Answers

Answer: it’s 8 to 14 number c

Step-by-step explanation:

Let me know if I’m wrong

The ratio equivalent to 20 to 35 is 8 to 14.

Option C is the correct answer.

What is a ratio?

The ratio shows how many times one value is contained in another value.

Example:

There are 3 apples and 2 oranges in a basket.

The ratio of apples to oranges is 3:2 or 3/2.

We have,

20 to 35

This can be written as,

= 20/35

= 5 x 4 / 5 x 7

= 4/7

Now,

5 to 7 = 5/7

7 to 5 = 7/5

8 to 14 = 8/14 = 4/7

14 to 8 = 14/8 = 7/4

Thus,

20 to 35 is the same as 8 to 14.

2x + 10 =- 4x – 9

Answers

Answer:

x = -19/6

General Formulas and Concepts:

Pre-Algebra

Order of Operations: BPEMDAS

Brackets Parenthesis Exponents Multiplication Division Addition Subtraction Left to Right

Equality Properties

Step-by-step explanation:

Step 1: Define Equation

2x + 10 = -4x - 9

Step 2: Solve for x

Add 4x on both sides:                    6x + 10 = -9Subtract 10 on both sides:             6x = -19Divide 6 on both sides:                  x = -19/6

Step 3: Check

Plug in x into the original equation to verify it's a solution.

Substitute in x:                    2(-19/6) + 10 = -4(-19/6) - 9Multiply:                               -19/3 + 10 = 38/3 - 9Add/Subtract:                      11/3 = 11/3

Here we see that 11/3 does indeed equal 11/3.

∴ x = -19/6 is the solution to the equation.
