Answer:

249 inches

Step-by-step explanation:

a cube is equal on all sides so if one side is 7 all sides are 7, if you multiply 7 by 7 you get 49 but that's just one face of the cube, there are 6 faces on a cube so 49 x 6 is 249

Answer:

angle relationship: same-side interior

value of x: 40

Step-by-step explanation:

the horizontal lines are parallel and the vertical line is the transversal, so 3x+x+20=180. combine the x's and subtract 20 from both sides to get 4x=160. then divide both sides by 4 to get x=40.

Answer:

y=-2x+5

Step-by-step explanation:

x-2y=2

2y=x-2

y=(x-2)/2

so the slope is 1/2

for lines to be perpendicular m1m2=-1 so the line must have a slope satisfying the condition

(1/2)m=-1

m=-2

the only line with a slope of -2

If is wrong i'm sorry

Answer:

-32

Step-by-step explanation:

To find w(-7) we have to substitute x with -7

w(x)=4x-4

w(x = -7) = 4(-7) -4

w(-7) = -28-4

w(-7) = -32

Answer:

On July 24, 2009, the federal minimum wage will increase to $7.25 per hour. This is the final step of a three-step increase passed in 2007 when the minimum wage was only $5.15. In this last step, about 4.5 million workers will receive a raise, providing an additional $1.6 billion annually in increased wages. However, when adjusted for inflation, the new federal minimum is still less than the minimum wage through most of the period from 1961 to 1981.

Answer: 8

Step-by-step explanation:

The 4 times of the number 8 results to 32.

A branch of mathematics known as algebra deals with symbols and the mathematical operations performed on them.

Variables are the name given to these symbols because they lack set values. In order to determine the values, these symbols are also subjected to various addition, subtraction, multiplication, and division arithmetic operations.

Given:

32 is 4 times as much as what number

let the number be x.

So, 4 times of x = 32

4x = 32

Divide both side by 4.

4x/4 = 32/4

x= 8

Hence, the 4 times of the number 8 results to 32.

Step-by-step explanation:

It is not commutative.

The relationship between the cost charged for the daily boarding of dogs

by the kennel is a directly proportional relationship.

The correct responses are;

1. The dog kennel charges $60 per day is; False

Correct statement; The dog kennel charges $30 per day

2. The equation y = 30·x can represent the graph; True

3. It costs $200 to board a dog for 7 days is; False

Correct statement; It costs $210 to board a dog for 7 days

4.The graph will contain the coordinate point (9, 270); True

Reasons:

Points on the graph of the given graph of the Cost to Number of days are;

(2, 60), (4, 120)

The slope of the graph is [tex]m = \dfrac{120 - 60}{4 - 2} = 30[/tex]

Equation of the graph is therefore; y - 60 = 30·(x - 2)

Which gives;

y  = 30·x - 2×30 + 60 = 30·x

The equation of the graph is; y = 30·x

Therefore, the statement;

The cost of the dog kennel a day is given by the value of 'y', when x = 1, as

follows;

Cost per day, y = 30 × 1 = 30

The cost per day = $30 per day

Therefore;

The correct statement is; The dog kennel charges $30 per day

The amount it costs to board a dog for 7 days is y = $30×7 = $210

Therefore, the correct statement is; It costs $210 to board a dog for 7 days

Therefore, the statement; the graph will contain the coordinate point (9, 270) is; True

Step-by-step explanation:

Simplify the ratio and put it in word form.

Answer:

For every three kittens there is one orange kitten

Step-by-step explanation:

The total number of kittens is equal to four black kittens + two orange kittens, which makes for six kittens.

So for every six kittens there are two orange kittens.

We can simplify this down further by dividing by the greatest common factor, 2.

So,

For every three kittens there is one orange kitten.

e)0.53÷0.006=88.333

g)3.61÷1.1=3.282

I)6.56÷0.09=73.889

Explanation:

The slope of any vertical line is always undefined. This is because [tex]\text{slope} = \frac{\text{rise}}{\text{run}}[/tex], and the "run" portion is 0. The run represents the change in x, but we don't have a change in x for vertical lines. The x value is always some constant.

So this is why the run is 0, and it leads to a division by zero error, causing an undefined slope.

[tex]\sf \longmapsto x + y = 7 \: \: - - - (i)[/tex]

[tex]\sf \longmapsto 3x - 2y = 11 \: \: - - - (ii)[/tex]

By first equation,

[tex]\sf \longmapsto x + y = 7[/tex]

[tex]\sf \longmapsto x = 7 - y[/tex]

Now, we can find the original value of y.

[tex]\sf \longmapsto 3x - 2y = 11[/tex]

[tex]\sf \longmapsto 3(7 - y) - 2y = 11[/tex]

[tex]\sf \longmapsto 21 - 3y - 2y = 11[/tex]

[tex]\sf \longmapsto 21 - 5y = 11[/tex]

[tex]\sf \longmapsto - 5y = 11 - 21[/tex]

[tex]\sf \longmapsto - 5y = - 10[/tex]

[tex]\sf \longmapsto y = \dfrac{ - 10}{ - 5} [/tex]

[tex]\sf \longmapsto y = 2[/tex]

Now, we can find the original value of x.

[tex]\sf \longmapsto x + y = 7[/tex]

[tex]\sf \longmapsto x + 2 = 7[/tex]

[tex]\sf \longmapsto x = 7 - 2[/tex]

[tex]\sf \longmapsto x = 5[/tex]

Therefore, the values of x and y are 5 and 2 respectively.

Answer:

m < FGN = 88°

Step-by-step explanation:

The exterior angle theorem states that the measure of each exterior angle of a triangle is equal to the sum of the opposite and non-adjacent interior angles (also known as remote interior angles).

Given the exterior angle, m <FGN = (7x + 18)°, and the two remote interior angles, m < E = 38° and m < F = (6x - 10)°:

The following equality statement can be established according to the exterior angle theorem:

m < E  + m < F  = m <FGN

38 + 6x - 10 = 7x + 18

Combine like terms:

28 + 6x = 7x + 18

Subtract 6x from both sides:

28 + 6x - 6x = 7x - 6x + 18

28 = x + 18

Subtract 18 from both sides:

28 - 18 = x + 18 - 18

10 = x

Next, substitute the value of x = 10 into the equality statement to determine whether it is the correct value of x, and to find the measures of < FGE and < F.

m < E  + m < F  = m <FGN

38° + (6x - 10)° = (7x + 18)°

38 + 6(10) - 10 = 7(10) + 18

38 + 60 - 10 = 70 + 18

88 = 88 (True statement).

Therefore, m < FGN = 88°
