Hey there!

4x - 16 + 2x + 16 = 180 (linear pair)

4x + 2x - 16 + 16 = 180

6x = 180

x = 180/6

x = 30.

Hope it helps ya!

Answer:

C

Step-by-step explanation:

Step 1: Determine the value of x by using [tex]x=tan^{-1}(\frac{\sqrt{3} }{\sqrt{2}} )[/tex]

[tex]x=tan^{-1}(\frac{\sqrt{3}}{\sqrt{2} })=50.7685 degrees[/tex]

Step 2: Substitute x=50.7685 degrees into the original equation

[tex]2cos^{4}(x)-sin(x)=2cos^{4} (50.7685)-sin(50.7685)=0.320-0.7746=-0.4546[/tex]

f ^− 1 ( x )  =  x/2  − 4

That is the inverse

The value of the function, for x=-2 is 4.

The given function is f(x)=2x+8.

Functions are the fundamental part of the calculus in mathematics. The functions are the special types of relations. A function in math is visualized as a rule, which gives a unique output for every input x.

When x=-2, we get

f(-2)=2(-2)+8

=4

When x=0, we get

f(0)=2(0)+8

= 8

When x=5, we get

f(5)=2(5)+8

= 18

Therefore, the value of the function, for x=-2 is 4.

Answer:

D 36

Step-by-step explanation:

Write the information algebraically

c = 3a

c + a = 48

c = children, a = adults

In the second sentence (in bold), we can replace c with 3a

c + a = 48 → 3a + a = 48

Simplify

3a + a = 48 → 4a = 48 → a = 12 (divide both sides by 4)

We can then substitute or plug in a = 12 into the original equation:

c + a = 48 → c + 12 = 48 → c = 36 (subtract 12 from both sides)

Answer:

First mechanic: $65.

Second mechanic: $60.

Step-by-step explanation:

Let the rates be x for the first mechanic and y for the second.

x + y = 125

10x + 5y = 950

Multiply first equation by - 5

-5x - 5y = -625

Adding the last 2 equations:

5x = 325

x = 65

y = 125-65 = 60 .

Answer: About 317.4 oz or 19 lbs! Pls Brainly Thx :D

Answer:

D) 19.8 lbs

Explanation:

1kg in household measurement is equal to 35.274 ounces. 35.274*9=317.466 ounces.

1kg is also equal to 2.205 lbs. 9*2.205=19.8416

9 kg is also equal to 9000 grams, but grams are not a part of the household measurement system

a) 9000 grams. b) 9000 ounces. c) 19.8 ounces. d) 19.8 pounds.

This leaves us with 19.8 lbs

Answer:

  y = 8

Step-by-step explanation:

If the variation is direct, any multiplier of the x-value will also multiply the y-value.

  old value × -1 = new value

  x: 4 × -1 = -4

  y: -8 × -1 = 8

The new value of y is 8.

Answer:

Step-by-step explanation:

Answer:

D)  

Step-by-step explanation:

y = 12x.

A) x=8, so that y = 12(8) = 96.  It's on the line

B) x = 10, so that y = 12(10) = 120.  It's on the line

C) x = 15, so that y = 15(12) = 180.  It's on the line

D) x = 18, so that y = 18(12) = 216, not equal to 206.  So, the point is not on the line.

Answer:

4294967296 Kilograms

Step-by-step explanation:

Great Pyramid has 2^21 blocks

2^21 = 2097152, so

2097152 blocks

Blocks weigh 2^11 each

2^11 - 2048, so

2048 kg per block

2097152(number of blocks) x 2048(weight in kilograms per block) = The Great Pyramid in Egypt weighs 4294967296 Kilograms

Step-by-step explanation:

More than 2,300,000 limestone and granite blocks were pushed, pulled, and dragged into place on the Great Pyramid. The average weight of a block is about 2.3 metric tons (2.5 tons).

How much is that? Well, you can think of it in terms of refrigerators. An average refrigerator weighs about 91 kg. If 1 metric ton = 1,000 kg, how many refrigerators equal a 2.3-metric ton block?

A 25 refrigerators

B 5 refrigerators

C 90 refrigerators
