Answer:

The value of x is 26.

Step-by-step explanation:

In a triangle, the total angles is 180°. In order to find the value of x, you have to add up all the angles in terms of x and make it equals to 180°

2x + 3x + 50 = 180

5x + 50 = 180

5x = 180 - 50

5x = 130

x = 130 ÷ 5

x = 26

As we know that,

Sum of all angles of triangle = 180°

Given,

Angles are 2x , 3x and 50°

Now,

[tex] \rightarrow \: 2x + 3x + 50 = 180[/tex]

When plus sign goes to another side then,it become minus.

[tex] \rightarrow \: 5x = 180 - 50[/tex]

[tex] \rightarrow \: 5x = 130[/tex]

[tex] \rightarrow \: x = \cancel \dfrac{130}{5} [/tex]

[tex] \rightarrow \: x = 26[/tex]

Hence,the value of x is 26°.

Answer:

The volume of the hemisphere  

       V = 121.33086 cubic centimeter

Step-by-step explanation:

Step(i):-

Given that the total surface area of a hemisphere = 45π cm²

The total surface area of a hemisphere = 3π r²

Equating

              3π r² = 45π

                   [tex]r^{2} = \frac{45}{3} =15[/tex]

                    r = [tex]\sqrt{15} = 3.87[/tex]

The radius of the sphere 'r' = 3.87

Step(ii):-

The volume of the hemisphere

                 [tex]V = \frac{2}{3} \pi r^{3}[/tex]

                [tex]V = \frac{2}{3} \pi (3.87)^{3}[/tex]

we know that   π = 3.14

                [tex]V = \frac{2}{3} (3.14) (3.87)^{3}[/tex]

               V = 121.33086 cubic centimeter

Answer:

x = -3

Step-by-step explanation:

Given expression is,

[tex]\frac{2}{x}- \frac{4x}{2x-3}=-2[/tex]

[tex]\frac{2(2x-3)}{x(2x-3)}-\frac{4x(x)}{x(2x-3)}=-2[/tex]

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

(4x - 6) - 4x² = -2x(2x - 3)

4x - 6 - 4x² = -4x² + 6x

4x - 6 = 6x

6x - 4x = -6

2x = -6

x = -3

Answer:

f(x)= -2|x-3|-1

(Hi Simran! I just wanted to help you with this question though it might be wrong)

Step-by-step explanation:

f(x) = a|x-h|+k

f(x)= a|x-3|-1

-7 = a |0-3| -1

-7 = a |-3| -1 <-- add to -7

-6 = a |-3|

-6 = 3a

-6/3 = a

-2 = a

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

The equation of the absolute value is f(x)= -2|x-3|-1

Answer:

Positive, Positive

Step-by-step explanation:

The only variable is an absolute value which means that as x approaches infinity it can only get bigger and bigger

Answer:  here's your answer

485 ft

Step-by-step explanation:

step 1

Find the distance from the base of the building to the base of the radio tower

Let

x -----> the distance from the base of the building to the base of the radio

we know that

tan(36°)=254/x

x=254/tan(36°)=349.60 ft

step 2

Find the distance from the base of the tree to the base of the radio tower

Let

x -----> the distance from the base of the tree to the base of the radio tower  

we know that

tan(62°)=254/x

x=254/tan(62°)=135.05 ft

step 3

Find the distance from the base of the building to the base of the tree

Adds the distances

349.60 ft+135.05 ft=484.65 ft

Round to the nearest foot

484.65 ft=485 ft

Answer:

K = 2y + 4

Step-by-step explanation:

Let K = Keith

The expression that can be used to find Keith's age will be K = 2y + 4.

An equation is a statement that two expressions, which include variables and/or numbers, are equal. In essence, equations are questions, and efforts to systematically find solutions to these questions have been the driving forces behind the creation of mathematics.

It given that, Keith is 4 years older than twice sheila's age. Sheila is y years old.

Suppose the age of Keith is shown by K and Sheila is y years old.

Expression is the combination of constants and variables with mathematical operators.

The expression can be used to find Keith's age is obtained as,

K = 2y + 4.

Thus, the expression that can be used to find Keith's age will be K = 2y + 4.

Answer:

A. 200

B. Growth

C. 118%

Step-by-step explanation:

Answer:

Initial population size=200

The function represents a growth

Step-by-step explanation:

Equation to calculate population size after time, t

P(t) = 200(1.18)^t

To find initial population size we will take t = 0

P(0) = 200(1.18)^0

      = 200(1)

      = 200

To find that function represent growth or decay

P(1) = 200(1.18)^1

     = 200(1.18)

     = 236

Its means that after a year population increases. Hence, function represent growth.

By what percentage does the population change each year?

(236 - 200 / 200) * 100%

= 235%
