2) (see image below)

3) x = 8  

   side(s) = 74

4) x = 10

   EF = DE = 67

   base = 31

Step-by-step explanation:

For No. 2, if you draw out two triangles with the corresponding angles, you can make it a lot easier. See the image below:

For No. 3, it is given that it's an equilateral triangle, meaning all sides and angles are congruent. So:

12x – 22 = 10x – 6 = 7x + 18

Instead of using all three at once, you can use any two. I'll be using:

12x – 22 = 10x – 6

2x = 16

x = 8

Plugging x in, we can get all the sides, because this is an equilateral triangle:

12x – 22

12(8) – 22

96 – 22

74

For No. 4, it is given that the triangle is an isosceles triangle where DE ≅ EF, so:

8x – 13 = 5x + 17

3x = 30

x = 10

Plugging in x for one of the congruent sides and the base, you can get your needed side length values:

8x – 13

8(10) – 13

80 – 13

67

x + 21

10 + 21

31

Answer:

Y=-5.6

x=.9

Step-by-step explanation:

Isolate the x:

6x=11+y

2x=7-3y

multiply top by 3 to get rid of y(3y and -3y cancel each other out)

18x=11

2x=7

put them together:

20x=18

divide by 20

x=0.9

to find y plug in x to the first equation:

y=6(.9)-11

y=5.4-11

y=-5.6

Answer:

350 kilómetros por hora son 97,2222 metros por segundo ;)

The result of converting 350 km/h to meter per second is 97.22 m/s.

To convert from kilometers per hour (km/h) to meters per second (m/s), you need to apply the conversion factor.

The conversion factor for this conversion is 1 km/h = 0.2778 m/s.

To convert 350 km/h to m/s, multiply 350 by the conversion factor:

350 km/h×0.2778 m/s

= 97.22 m/s

Therefore, the result of converting 350 km/h to m/s is approximately 97.22 m/s.

Answer:

Subject 's' in terms of 't'

  [tex]s = \frac{t-4}{5}[/tex]

Step-by-step explanation:

Explanation:-

Given that the subject 't in terms are 's'

Given that t = 5 s +4

subtracting '4' on both sides, we get

t - 4 = 5s +4-4

 t - 4 = 5 s

Dividing '5' on both sides ,we get

  [tex]\frac{t-4}{5} = \frac{5s}{5}[/tex]

   [tex]\frac{5s}{5 } = \frac{t-4}{5}[/tex]

Answer:

s=6

Step-by-step explanation:

Hope this helps :)

The value of s for the given expression 3(s + 4 = 30 will be 6.

A mixture of variables, numbers, addition, subtraction, multiplication, and division are called expressions.

A statement expressing the equality of two mathematical expressions is known as an equation.

As per the given expression,

3(s + 4) = 30

Divide both sides by 3

s + 4 = 10

Subtract both sides by 4

s + 4 - 4 = 10 - 4

s = 6

Hence "The value of s for the given expression 3(s + 4 = 30 will be 6".

Answer:

Step-by-step explanation:

equation for x

according to the question

110°+x=180°

x=180°-110°

x=70°

equation for y

according to the question

[tex]11 {0}^{o} + {40}^{o} + y = 18 {0}^{o} [/tex]

[tex]15 {0}^{o} + y = 180^{o} [/tex]

[tex]y = 18 {0}^{o} - 15 {0}^{o} [/tex]

[tex]y = 3 {0}^{o} [/tex]

equation for z

according to the question

90°+x+z=180°

90°+70°+z=180° (since x=70°)

160°+z=180°

z=180°-160°

z=20°

Answer:

X= 70

Z= 20

y= 30°

Step-by-step explanation:

Finding X:

Sum of angle in a straight line is 180

Therefore X = 180-110

Finding z:

Sum of angle in triangle is 180, and it’s a right angled triangle (90°)

Z= 180-(x+90)

Z= 180-( 70+90)

Finding y, look at the big triangle ABC:

There’s a right angle and <C is 40°,

Therefore <B is 180-(40+90)= 50°

<B= y + z

50° = 20° + y

y= 30°

Step-by-step explanation:

The closest probability of a randomly selected person in the city having red hair is approximately 0.03 (or 3%).

Probability is defined as the possibility of an event being equal to the ratio of the number of favorable outcomes and the total number of outcomes.

A certain city has a population of around 100,000 people. In the city, there are 3,101 people with red hair.

The required probability can be calculated by dividing the number of people with red hair by the total population of the city:

= 3,101 / 100,000

= 0.03101,

It can be rounded to 0.03.

Thus, the required probability is 0.03.

Answer:

Total number of employees = 86,891 employees

Step-by-step explanation:

Let

x = total number of employees

26.7% of x = 23,200

26.7/100 * x = 23,200

0.267 * x = 23,200

0.267x = 23,200

x = 23,200/0.267

x = 86,891.385767790
