Answer:

x=18

Step-by-step explanation:

Vertical angles mean that the angles are the same, diagonal from each other.

So, you can assume that <1=<3,

4x-14=58

Solve this as an equation

58+14=72

72/4=18

x=18

So because they are Vertical angles, they are equal! The equation would be (4x-14)=58. When you solve for that, you get x=18

Write an equation for the line that passes through the points 0,-6 and -3,0

A circle has a diameter of 14 ft. What is the area of the circle? (use 3.14 for )

A. 43.96 ft²
B. 87.92 ft²
C. 153.86 ft²
D. 615.44 ft²

Answers

Answer:

answer is C. 153.86ft^2

Answer:

C 153.86ft²

Step-by-step explanation:

The formula is πr²

This mean you first find the radius of the circle which is half of the diameter. so for this circle the radius is 7ft.

Now plug everything in the formula and solve

3.14×7²

Following bedmas you would do exponents first. 7²=49

Now do 3.14×49 which is 154.86ft²

−2x − 10 = 15 I'm really un smart

Answers

Answer:

x = -12.5

Step-by-step explanation:

your goal is to get x alone so

-2x - 10 = 15

(add ten to both sides)

-2x = 25

(divide -2 to both sides)

x = -12.5

remember that whatever u do to one side of the equation, you have to do to the other so they even out!

Which BEST describes how the human circulatory and respiratory systems interact?
A.
The heart removes waste built up in the lungs.
B.
Oxygen enters the bloodstream directly from the nose.
C.
Oxygen is transferred to the bloodstream as blood passes by the lungs.
D.
The heart pumps air into the blood through the lungs.

Answers

C should be the answer

Option C is the best description of how the human circulatory and respiratory systems interact, as it accurately reflects the process by which oxygen is transferred to the bloodstream as blood passes by the lungs.

How do the human circulatory and respiratory systems interact?

The circulatory and respiratory systems work together to ensure that oxygen is delivered to the body's cells and carbon dioxide is removed. The respiratory system is responsible for taking in oxygen and expelling carbon dioxide, while the circulatory system is responsible for transporting oxygen and nutrients to the body's cells and removing waste products.

During respiration, oxygen is taken in through the nose and mouth and travels down the trachea, or windpipe, and into the lungs. In the lungs, oxygen is transferred to the bloodstream through tiny blood vessels called capillaries. At the same time, carbon dioxide is removed from the bloodstream and expelled through the lungs during exhalation.

The heart plays a crucial role in the circulatory system by pumping blood through the body, including through the lungs. As blood flows through the lungs, it picks up oxygen and releases carbon dioxide, which is then transported to the heart and pumped out to the rest of the body.

Therefore, oxygen is transferred to the bloodstream as blood passes by the lungs.
