Answer:

first angle is 24

second angle is 108

third angle is 48

all the three angles of the triangle add up to 180

(its a rule)

then 2+9+4=15

180÷15=12

12×2=24

12×9=108

12×4=48

Answer:

Step-by-step explanation:

You really don't have enough information to solve this with one answer. You want a value for y and there is no what to limit it to just 1 set of values. For example if x = 23 then

x = y + y - 3

x = 2y - 3

23 = 2y - 3           Add three to both sides

23+3 =  2y           Combine

26 = 2y                Divide by 2

26/2 = 2y/2          Do the division

13 = y

The smaller number is 13 - 3 = 10

Their sum is 13 + 10=23           But that answer is not unique.

====================

Suppose x = 13

13 = 2y - 3              Add 3

13 + 3 = 2y

16 = 2y

y =8

The larger number = 8

The smaller number = 5

=======================

The best I can do is give you the equation which is

x = 2y - 3

Answer:

a) x=38

b) x=19

Step-by-step explanation:

a) The interior angles at L and M can be found by subtracting 134 and 84 from 180 respectively:

∠L = 180 - 134 = 46

∠M = 180 - 84 = 96

The angles of a triangle sum up to 180, so x + 46 + 96 = 180.

From this you find that x = 180 - 46 - 96 = 38

b) Because YZ and XW are parallel, ∠Y=∠W = 2x

The sum of the angles in the triangle must be 180, so

3x-5 + 90 + 2x = 180

Which simplifies to

5x +85 = 180

5x = 95

x = 19

Answer:

a) x = 38°; b) x = 19°  

Step-by-step explanation:

a)

∠OLM = 180 - 134 = 46°     Supplementary angles

∠OML =180 -   84 = 96°     Supplementary angles

         x + 46 + 96 = 180     Interior angles of triangle

                x + 142 = 180

                          x =   38°

===============

b)

∠XWY + 3x - 5 + 90 = 180         Interior angles of triangle

     ∠XWY + 3x + 85 = 180

(1)          ∠XWY + 3x = 95

                         ∠XWY = 2x

(2)           ∠XWY - 2x = 0           Alternate interior angles

                                5x = 95     [2 subtracted from (1)]

                                  x = 19°

Answer:

Step-by-step explanation:

Given speed of Charlotte in kilometer per hour = 9 km/h

We need to find the Charlotte's speed in meter per second.

We know 1 kilometer = 1000 meter

And 1 hour = 3600 seconds.

Plugging those values of km and hour in given speed in km/h, we get

[tex]9\ \frac{km}{h} = 9\times \ \frac{1000m}{3600 seconds}[/tex]

[tex]=\frac{10m}{4s}= 2.5\ m/s[/tex].

Therefore,

Answer:

Speed of Charlotte in a Unit which includes Km and hour [tex]=9 \frac{\text{Km}}{\text{hour}}[/tex]

1 Km=1000 meter

1 hour=60 minutes=3600 seconds

Speed of Charlotte in a Unit which includes meter and second is

                     [tex]=\frac{9 \times 1000}{3600}\frac{\text{meter}}{\text{seconds}}\\\\=\frac{90}{36}\frac{\text{meter}}{\text{seconds}}\\\\=\frac{5}{2}\frac{\text{meter}}{\text{seconds}}[/tex]

Answer:

Step-by-step explanation:

Answer:

1.X= 8 or 1

2.X= 3 or -1

3. X = 5/14

Step-by-step explanation:

1. Expanding your original equation (x-6)(2x-6)=20) , you get 2x^2-18x+36=20. Then, subtract 20 from both sides. You  get 2x^2-18x+16=0. Now this is a standard Quadratic equation. Use the quadratic Formula to solve this, you get   X= 8 or 1.

2. 1. Expand : x²+6x+9-8x-12=0    2. Simplify : x^2-2x-3=0  3. Solve as a quadratic equation : x= 3 or -1.

3. Same thing as the first one!

Answer:

x = 23

Step-by-step explanation:

the sum of the 3 angles in a triangle = 180°

the third angle forms a straight angle with 100°, hence

third angle in triangle = 180° - 100° = 80°

Summing the 3 angles gives

2x + 3 + 80 + 51 = 180

2x + 134 = 180 ( subtract 134 from both sides )

2x = 46 ( divide both sides by 2 )

x = 23

Answer:

Vertical shift is 2 units top and horizontal shift is [tex]\frac{\pi }{2}[/tex] units to the right

Step-by-step explanation:

Consider the function f(x) = a cos(bx + c) + d.

In this graph, the horizontal shift is -c/b and the vertical shift is d.

Let's compare our graph, f(x) = -3 cos(2x - π) + 2 with this graph.

Here, a = -3, b = 2, c = -π and d = 2.

So, vertical shift = d = 2 units top and

horizontal shift = [tex]-\frac{c}{b} =-\frac{-\pi }{2} =\frac{\pi}{2}[/tex] units to the right.

Answer:

Step-by-step explanation:

Answer:the answer is 75%

Step-by-step explanation:

Martin will earn 75% of his regular hourly rate during his training period, which is calculated by dividing the training hourly rate ($15) by the regular hourly rate ($20) and multiplying by 100%.

To determine what percent of Martin's regular hourly rate he will earn during training, we need to compare his training wage to his regular wage. Martin's regular hourly rate is $20 per hour, and during training, he earns $15 per hour.

The percentage can be calculated using the formula:

Percent Earned During Training = (Training Hourly Rate / Regular Hourly Rate) x 100%

Now, plug in Martin's earnings:

Percent Earned During Training = ($15 / $20) x 100%

Percent Earned During Training = 0.75 x 100%

Percent Earned During Training = 75%

Therefore, Martin will earn 75% of his regular hourly rate during his training period.

Answer:

Approximately 1.5 cups/hour

Step-by-step explanation:

Divide 214 cups by 145 hours.

(214 cups)/(145 hours) = 1.47586... cups/hour

Remy drinks around 1.47 cups of water in an hour. This was calculated by dividing the total cups (214) by total hours (145).

To solve this question, we need to calculate the rate at which Remy drinks 214 cups of water every 145 hours. This can be done by dividing the total number of cups by the total number of hours.

So, the formula we have is:Cups per hour = Total Cups / Total hours

This gives us:Cups per hour = 214 / 145

After calculating this, you will find that Remy drinks approximately 1.47 cups of water in 1 hour.

Answer: There are four possible solutions

Step-by-step explanation:

I was unable to manipulate this system to develop solvable equations, so I made a table consisting of 7 rows with the following 5 columns:

Table 1

Answer:

[tex]y\leq -x-5[/tex]

Step-by-step explanation:

First you find the equation of the line. Start by finding the slope of the line, using the two points given: (-5,0), (0,-5).

[tex]\frac{0--5}{-5-0} = \frac{5}{-5} = -1[/tex]

The y intercept is -5.

Your equation is then y = -1x-5.

To find which inequality to use, plug in a point within your region and see if the statement is true. I would choose (-3,-3)

-3 __ -1(-3)-5

-3 __ -2  you would fill this in with a <, so that is what goes in your equation. since the line is solid and  not dotted, you include the underline in the sign.

Answer:

B  2X-3Y=12

C -4(2X-3Y)=-4(12)

Step-by-step explanation:

y = 2/3 x -4

multiply by 3

3y = 2x -12   factor out a 2    3y = 2(x-6)

subtract 2x from each side

-2x+3y = -12

multiply by -1

2x-3y = 12

multiply by -4

-4(2x-3y) = -4(12)

The slope-intercept form: y = mx + b.

The standard form: Ax + By = C.

We have:

[tex]y=\dfrac{2}{3}x-4[/tex]       multiply both sides by 3

[tex]3y=2x-12[/tex]     subtract 2x from both sides

[tex]-2x+3y=-12[/tex]       change the signs

[tex]2x-3y=12\to\boxed{B.}[/tex]      multiply both sides by (-4)

[tex]-4(2x-3y)=-4(12)\to\boxed{C.}[/tex]

A. 3x - 2y = 4   - NOT

D. 2(x + 6) = 3y → 2x + 12 = 3y → 2x - 3y = -12      - NOT

E. 2x - 3y = 4    - NOT

Answer: The 6th term is 45

Given that two rabbits are gray and they represent 1/8 of all rabbits at a pet store, calculated using ratios, it can be inferred that the total number of rabbits is 16.

The question is asking about the total number of rabbits in a pet store given that 1/8 of the total rabbits are gray and there are two gray rabbits. We can use this information to set up a ratio to calculate this.

To find out the total number of rabbits, we can set up a proportion where 2/total rabbits = 1/8. By cross multiplying, we find that 2 * 8 = total rabbits. Therefore, the pet store has 16 rabbits.

Answer:

[tex]4\sqrt{10}[/tex]

Step-by-step explanation:

We have been given that point A has the coordinates(2,5) point B has the coordinates (6,17).

To find the length of segment AB we will use distance formula.

[tex]\text{Distance}=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}[/tex]

Upon substituting coordinates of point A and point B in distance formula we will get,

[tex]\text{Distance between point A and point B}=\sqrt{(6-2)^2+(17-5)^2}[/tex]

[tex]\text{Distance between point A and point B}=\sqrt{(4)^2+(12)^2}[/tex]

[tex]\text{Distance between point A and point B}=\sqrt{16+144}[/tex]

[tex]\text{Distance between point A and point B}=\sqrt{160}[/tex]

[tex]\text{Distance between point A and point B}=4\sqrt{10}[/tex]

Therefore, the length of segment AB is [tex]4\sqrt{10}[/tex].
