The difference of the same side interior angles of two parallel lines is 50°. Find all angles.

Answer:$400

Step-by-step explanation:

Because, if she spent ONLY 1/5 of her money, and she has $80 left, wouldn't you basically have to multiply 5 with 80 to get the original amount of money?

Answer:

$100

Step-by-step explanation:

If Maryna had $80 after spending 1/5, we know she has 4/5 left. Then, we divide 80 by 4/5. To divide a fraction, we multiply the number by rhe reciprocal. So, we multiply 80/1 by 5/4. 80 multiplied by 5 is 400, and divided by 4 is 100. This is how we get an original amount of $100.

Answer:

x = 11, y = 8

Step-by-step explanation:

ΔABC and ΔFDE are congruent by the postulate SSS

Equate the congruent sides in the 2 triangles

BC = ED, that is

x + 3 = 14 ( subtract 3 from both sides )

x = 11

-------------------------------------

DF = AB, that is

x - y = 3 ← substitute x = 11

11 - y = 3 ( subtract 11 from both sides )

- y = 3 - 11 = - 8 ( multiply both sides by - 1 )

y = 8

Answer:

The value of x is 11 and the value of y is 8.

Step-by-step explanation:

It is given that ∆ABC and ∆FDE are congruent.

The corresponding parts of congruent triangle are congruent.

[tex]AB=FD[/tex]                       (CPCTC)

[tex]3=x-y[/tex]                 .... (1)

[tex]BC=DE[/tex]                       (CPCTC)

[tex]x+3=14[/tex]

Subtract 3 from both the sides.

[tex]x=14-3[/tex]

[tex]x=11[/tex]

The value of x is 11.

Put x=11 in equation (1).

[tex]3=11-y[/tex]

Add y on both the sides.

[tex]3+y=11[/tex]

Subtract 3 from both the sides.

[tex]y=11-3[/tex]

[tex]y=8[/tex]

The value of y is 8.

Answer: 6 units

Step-by-step explanation:

Area = 1/2 (base1 + base2) X height <-------- Formula for a trapezoid

24 = 1/2 (2 + 6) X h <----- We know that the area of the trapezoid is 24 units

squared and that both of the bases are 2 units and 6 units.

24 = 1/2 (8) X h <------- Add 6 + 2

24 = 4 X h <-----  Half of 8 is 4

h = 6 <------  6 X 4 = 24 , therefore the height is 6 units.

Answer:

4,582,500

Step-by-step explanation:

(30,000*611)/4=4,582,500

Answer:

Quarterly budget of $4582500 must be allocated.

Step-by-step explanation:

A facility spends on its inmates of an average = $30000 annually

Number of inmates = 611

Total amount to be spent = $30000×611

= $18330000

Since there are 4 quarters in a year so quarterly budget allocated

= [tex]\frac{18330000}{4}[/tex]

= $4582500

Therefore, quarterly budget of $4582500 should be allocated.

1 ) Watts =E * I = 110 * 5 = 550 watts =.55 KW  

2) I = Watts / e = 1100 / 110 = 10 amperes  

3) 1 horsepower = 33000 ft/lbs per minute  

HP = ( 2000 * 1000) / (33000 *4) = 15.1515 hp  

4) cost = (10 * 100 / 1000) *11 * $0.10 = $1.10  

5) This answer will be incorrect because you have not stated the power factor of the motor.  

va = I * E = 7.5 * 240 = 1800  

2 hp = 2 * 746 watts = 1492 watts  

If the motor had a 1.0 power factor (it doesn't) the efficiency would be  

efficiency = output / input = 1492 / 1800 = 82.888 %  

6) I = watts / E =1000 / 120 = 8.333 amps  

7) 1 = watts / E = 1000 / 240 = 4.1616  

8) Kw-hr = (2 * 24 * 365 ) / 1000 = 17.52  

cost = kw-hr * $0.03 = 17.52 * $0.03 = $0.5256  

9) efficiency = (115 * 240) / (2400 * 12) = 95.8333 %  

10) KW = (I^2 * R) / 1000 = (20^2 * 5) / 1000 = 2  

the current required is 10 amperes.

To calculate the current required for a device rated at 1,100 watts operating at 110 volts, we use the formula P = IV, where P is power in watts, I is current in amperes, and V is voltage in volts.

Rearranging the formula to solve for current, we get I = P / V. Plugging in the given values, we have:

I = 1,100 W / 110 V

Thus, the current required is 10 amperes.

Answer:

Step-by-step explanation:

[ (x + 7) / 6 ] − [ (x + 5) / (x + 3) ]

First, we must find the common denominator.  In this case, that's 6 (x+3).  Multiply the first fraction by (x+3)/(x+3) and the second fraction by 6/6.

[ (x + 7)(x + 3) / (6 (x + 3)) ] − [ 6 (x + 5) / (6 (x + 3)) ]

Now distribute the numerators:

[ (x² + 10x + 21) / (6 (x + 3)) ] − [ (6x + 30) / (6 (x + 3)) ]

Now we combine the fractions:

((x² + 10x + 21) − (6x + 30)) / (6 (x + 3))

(x² + 10x + 21 − 6x − 30) / (6 (x + 3))

(x² + 4x − 9) / (6 (x + 3))

So the simplified form is:

[tex]\frac{x^{2} + 4x - 9}{6 (x + 3)}[/tex]

f(x) − 2

Step-by-step explanation:

The function [tex]y=3 (2) ^ x[/tex] passes through point (0, 3) because:

[tex]f (0) = 3 (2) ^ 0 = 3 (1) = 3[/tex]

Then, if the transformed function passes through the point (0, 1) then this means that the graph of [tex]y = 3 (2) ^ x[/tex] was moved vertically 2 units down.

The transformation that displaces the graphically of a function k units downwards is:

[tex]y = f(x) + k[/tex]

Answer:

The length of the line segment is 13 units

Step-by-step explanation:

The line segment joining the two points is horizontal since the y co-ordinate is the same.

For a horizontal line, the length of the line segment is simply the difference between the x co-ordinate values.

In this case we have;

7 - (-6) = 7 + 6 = 13

Therefore, the length of the line segment is 13 units

Answer:

your answer is 13 units

Step-by-step explanation:

y = mx + b

m = slope

b = y-intercept

Since it is parallel to the equation y = 3x it means that the equation that goes through point (-1, 0) has the same slope (3x)

To find the b plug the x and y of point (-1, 0) into the equation: y = 3x + b then solve for b

0 = 3(-1) + b

0 = -3 + b

0 + 3 = (-3 + 3) + b

3 = b

so...

y = 3x + b

~Just a girl in love with Shawn Mendes

Answer:

y = 3x - 3

Step-by-step explanation:

Since our line is parallel to y = 3x, our slope should be 3. We also have the points (-1, 0).

From here, we can use the point-slope form (how convenient):

y - y₁ = m(x - x₁), where (x₁, y₁) is the given coordinate on the line, and m is the slope of the line

Plug in: y - 0 = 3(x - 1)

We could leave it here, but we should convert this line into the more commonly-seen slope-intercept form.

Distribute: y - 0 = 3x - 3

Identity: y = 3x - 3

Step-by-step explanation:

The mode in a stem-and-leaf plot is determined by identifying which leaf (end digit of a data point) occurs most often for a particular stem (leading digit(s)). For example, in the data set 4, 5, 6, 6, 6, 7, 7, 7, 7, 7, 7, 8, 8, 8, 9, 10 the mode is 7 as it appears most frequently.

The stem-and-leaf plot is a type of graph that provides a visual representation of data. It is a way of organizing data in which we can easily discover the mode, mean, median, and even the shape of the distribution (such as skewness). The mode in a data set is the value that appears the most often. In the context of a stem-and-leaf plot, identifying the mode involves finding which 'leaf' or end digit of a data point (the last digit in a number) occurs most frequently on a particular 'stem' or leading digit (all but the last digit of a number).

For example, in the stem-and-leaf plot of the data set given : 4, 5, 6, 6, 6, 7, 7, 7, 7, 7, 7, 8, 8, 8, 9, 10 the mode is 7 as the number '7' shows up the most often, which is 6 times. For identifying the mode, we closely look at the list of leaf values for each stem value and determine which leaf occurs more frequently than any other. Therefore, to answer the student's question about finding the mode from a stem-and-leaf plot, they simply need to identify which leaf value occurs most frequently in the data set presented in the plot.

Out of these 4, Matt has to do chores if two heads are flipped. It is 1/4 chance.

Out of these 4, Mark has to do chores if two tails are flipped. Again, 1/4 chance.

To flip again, they would have to get either HT or TH out of the 4 choices. So 2/4=1/2 is the likeihood they must flip again.

The k-th root's inverse function is raising to the k-th power.

So, if we raise the k-th root of some number x to the k-th power, we have applied a function and its inverse to x, and we must get x itself as output:

[tex]f(f^{-1}(x))=f^{-1}(f(x))=x\quad\text{for every invertible function f}[/tex]

So, in our case, we have

The equation that Arlene claim should be [tex]x^{k.\frac{1}{k}} \ = x^1 = x[/tex]

The k-th root's inverse function should be raising with respect to the k-th power.

Thus, in the case if we raise the k-th root of some number x to the k-th power, so here we used the function and its inverse to x, and we must get x itself in an output:

I believe that it has two solutions

Answer:

Step-by-step explanation:

To find the solution to the problem given, we will follow the steps below;

5x + 3x - 4 = 10

We will first start by simplifying

8x - 4 = 10

Add 4 to both-side of the equation

8x - 4 + 4 = 10 + 4

8x = 10

Divide both-side of the equation by 8

8x/8 = 10/8

At the left-hand side of the equation, 8 will cancel-out 8 leaving us with just x while at the right-hand side of the equation 10 will be divided by 8

x=1.25

Therefore the given equation has just one solution
