Answer:

11/4

Step-by-step explanation:

Hope this helps!

Step-by-step explanation:

Hey there!

By looking through figure, l and m are parallel lines and a transversal line passes through the lines.

Now,

7x + 12° = 12x - 28°( alternate angles are equal)

12°+28° = 12x - 7x

40° = 5x

[tex]x = \frac{40}{5} [/tex]

Therefore, x = 8°

Now,

12x - 28° + 9y - 77 = 180° ( being linear pair)

12×8° - 28° + 9y -77° = 180°

96° - 28° + 9y - 77° = 180°

-9 + 9y = 180°

9y = 180° + 9°

y = 189°/9

Therefore, y = 21°

Therefore, X = 8° and y= 21° .

Hope it helps....

Answer:

Let's see what to do buddy...

Step-by-step explanation:

_________________________________

Step (1)

First we need two points of the table :

I choose a = ( 0 , 3 ) and b = ( 2 , 0 ) .

_________________________________

Step (2)

To find the slope of linear functions using two points, we use the following equation :

[tex]slope = \frac{y(b) - y(a)}{x(b) - x(a)} \\ [/tex]

Where a and b are two points of the function.

_________________________________

Step (3)

Now just need to put the coordinates of the points which we chose.

a = ( 0 , 3 ) °•°•°•°•°•°•° b = ( 2 , 0 )

[tex]slope = \frac{0 - 3}{2 - 0} \\ [/tex]

[tex]slope = - \frac{3}{2} \\ [/tex]

And we're done.

Answer:

$18

Step-by-step explanation:

we proceed by first solving for the unit cost of a sheet

then calculate the cost for any number of sheet

We are told that a builder could buy 6 sheets for the cost of $9

this means that one sheet would cost 9/6= $1.5

Now the builder buys 12 sheets

therefore the cost of 12 sheets will be

12*1.5= $18

Answer:

20:1

Step-by-step explanation:

It is given that,

Input voltage = 260 volt

Output voltage = 13 volt

We need to find the ratio of the number of input wire coils to output wire coils on the transformer.​

For a step-down transformer,

[tex]\dfrac{V_i}{V_o}=\dfrac{N_P}{N_S}\\\\\dfrac{N_P}{N_S}=\dfrac{260}{13}\\\\=\dfrac{20}{1}[/tex]

Hence, the required ratio is 20:1.

Answer:

If two quantities x and y are related by y = f(x), the derivative f'(xo) represents the rate of change of y with respect to x at the point xo. It is measured in (units of y)/(units of x). A positive rate of change is sometimes called a rate of increase.

Step-by-step explanation:

Slope is positive and it goes up by 1 so it is just 1 and the y-intercept is 4 so it is y=x+4

Answer:

4π + 33 or 45.6

Step-by-step explanation:

For this question, you need to identify the perimeter of the semicircle and the 3 sides of the trapezoid.

The perimeter of the semicircle would be (this is the equation for a circle divided by two):

(2πr)/2 or (πd)/2

To figure this out, you don't need to know the radius, because you can just use the diameter, in which case if you plug it in you would get:

(8π)/2

→ 4π

Now you would just add the perimeter of the semicircle to the perimeter of the 3 sides of the trapezoid to get:

4π + (10+13+10)

→ 4π + 33

Now all you'd need to do is round 4π to the tenths place to get:

12.6 + 33

→ 45.6

Answer:

y=9x-17; x=17/9 or x=1 8/9 or x=1.8

y=x+23; x= -23

Step-by-step explanation:

y=9x-17

0=9x-17 (Move variables to the left-hand side and change its sign)

-9x=-17 (Divide both sides of the equation by -9)

x=17/9, x=1 8/9, or x=1.8

y=x+23

0=x+23 (To find x-intercept/zero, substitute y=0)

-x=23 (Move variable to the left-hand side and change its sign)

x= -23 (Change the signs on both sides of the equation)

x= -23

Answer:

x = 5

y = 28

the expressions both equal y so they are equal to each other.  so you right the equation as

9x - 17 = x + 23

then you subtract x from both sides

and then add 17 to both sides

the final step is to divide 8 on both sides and that gives you the answer x = 5. then you plug that back into the problem so...

y = 5 +23

so y = 28.

The mean difference in the game scores over six games is 2.5

The mean difference measures the absolute difference between the mean value in two different groups.

Given is a basketball team which played six games such that in those games, the team won by 8 points, lost by 11, won by 7, won by 11, lost by 4, and won by 13 respectively.

The mean difference of the given data can be calculated using the following formula -

Mean Difference = (∑W / n) - (∑L / n)

Where -

(∑W / n) is the mean of games won.

and

(∑L / n) is the mean of games lost.

(∑W / n) = (8 + 7 + 11 + 13)/4 = 9.75

and

(∑L / n) = (11 + 4)/2 = 15/2 = 7.5

Mean difference =  (∑W / n) - (∑L / n) = 9.75 - 7.5 = 2.5

Therefore, the mean difference in the game scores over six games is 2.5

Answer:

$36

Step-by-step explanation:

orig price = $40

discount=10%

40*10/100= 400/100 = 4

$40-4= $36

Answer:

$4

Step-by-step explanation:

x percent = x/100

10 percent = 10/100 = 0.10

10% of $40 = 0.10*40 = 4

You save $4

The old price is $40 and changes to $36 after the discount is applied. This is ignoring any taxes or other surcharges
