The figure is a square. Its diagonals meet to form four right
angles. What is the approximate value of x?
O 2.8 units
O 3.3 units
O 4.0 units
O 5.7 units
Answers
Answer:
D
Explanation:
ed2020
The approximate value of x is 5.7 units. It can be determined by Pythagoras' theorem. Therefore, option D is correct.
What is Pythagoras' theorem?Pythagoras' theorem is a fundamental theorem in mathematics. It describes the relationship between the sides of a right-angled triangle. It states that the square of the length of the hypotenuse (the side opposite the right angle) is equal to the sum of the squares of the lengths of the other two sides. Mathematically it is expressed by: H² = B² + P²
Given,
Base = x units
Perpendicular = x units
Hypoteneus = 8 units
The triangle formed in the figure is a right-angle triangle.
Thus, by Pythagoras' theorem,
H² = B² + P²
8² = x² + x²
64 = 2x²
x² = 64/2
x² = 32
x = √32
x = 5.7 units
Therefore, the correct option is D.

Choose a music instrument. Describe the types of energy involved in playing the instrument. State whether playing the instrument is an energy transfer or energy transformation.
Answers
Answer: Flute.
Explanation:
*1.* Once the air in the flute is vibrating, some of the energy is radiated as sound out of the end and any open holes. A much greater amount of energy is lost as a sort of friction (viscous loss) with the wall. In a sustained note, this energy is replaced by energy put in by the player
*2.* Energy Transfer. The ball's kinetic energy is transformed into gravitational potential energy as it rises through the air. This is converted back into kinetic energy as it falls. In most energy transfers and transformations, a small amount of energy is lost to the surrounding air as heat and sound energy.

In an electrical wire, if instead of copper, plastic wire is used. Would it conduct electricity?Justify your answer.
Answers
Answer:
No, a plastic wire would not conduct electricity. This is because plastic is an insulator that does not allow electric current to flow through it. In a wire, electrical conductivity is provided by the movement of charged particles - typically, electrons. Copper is an excellent conductor of electricity because it has a high number of free electrons that are not bound to atoms and can move through the wire very easily. However, in a plastic wire, the tightly bound electrons of its atoms do not allow for the free flow of charges, thus preventing the passage of electric current.

1. Using D10W and a vial of NaCl 4 mEq/mL, how many mL of NaCl are needed to prepare 250 mL of a
D10/NS solution?
a. 4.8mL
b. 9.6ml
c. 19.6mL
d. 154mL
Answers
To prepare 250 mL of a D10/NS solution using D10W and a vial of NaCl 4 mEq/mL, you would need 9.6 mL of NaCl. Normal saline (NS) contains 154 mEq/L of sodium chloride (NaCl). To prepare 250 mL of NS, you would need 250 mL * (154 mEq/L) = 38500 mEq of NaCl. Since the vial of NaCl contains 4 mEq/mL, you would need 38500 mEq / (4 mEq/mL) = 9625 mL = 9.6 mL of NaCl. So the correct answer is b. 9.6ml.

what is the relationship between convince and suspect?
Answers
To convince someone means to persuade them to believe or do something. This involves gaining their trust and making them feel confident in your argument or proposal.
On the other hand, to suspect someone means to have doubts or distrust about their motives or actions. This involves questioning their credibility and being cautious about their intentions.
So, while convincing involves building trust and confidence, suspecting involves the opposite - doubting and being cautious.

in diagram of the heart, the right side is colored blue to indicate its low in oxygen and high in ____________
Answers
Answer:
CO2 (Carbon dioxide)Explanation:
The right side is collored blue to indicate that the blood pumping through here is low on oxygen, but high in carbon dioxide. Because the blood is so low on oxygen, and high in carbon dioxide (a byproduct of Cellular Respiration), the blood will be pumped to the lungs where the CO2 is removed, and oxygen is taken in.
Normally the pressure on the right side of the heart and in the pulmonary arteries is lower than the pressure on the left side of the heart and in the aorta. This is because: the right side of the heart pumps blue (deoxygenated – little or no oxygen) blood returning from the body back to the lungs.
