Answer:
Explanation:
2 sheets of plywood will be needed.
Step-by-step explanation:
See the attached diagram.
Each three square plywood has area 1 units by 3 units = 4 feet by 12 feet = 48 feet square. {Since each unit on the coordinate plane represents four feet}
Now, the two triangular plywood has area half of a unit square area.
So, two triangular plywood has total area = 1 unit by 1 unit = 4 feet by 4 feet = 16 feet square.
Therefore, the total area of plywood required to make the triangular prism is (48 + 16) = 64 feet square.
Now, if a sheet of plywood measures 4 ft by 8 ft i.e. 32 feet square, then the carpenter will need such sheets of plywood. (Answer)

Each of the following statements is arguably true of thermometers. Which of them is most helpful to keep in mind if you are conducting an experiment to measure the specific heat of a material?
The statement that is true of thermometers is; The temperature reported by a thermometer is never precisely the same as its surroundings.
What is the function of thermometer in an experiment?In the experiment to determine the specific heat of a material, the theory will be one which explains that when a heat interchange takes place between two bodies that were having different temperatures at the beginning, the quantity of heat the warmer body looses is equal to that gained by the cooler body to reach the equilibrium temperature. This is true only if no heat is lost or gained from the surrounding.
Now, If heat is gained or lost from the surrounding environment, the temperature readings by the thermometer will be incorrect. The experimenter should therefore have in mind that for accurate results, the temperature recorded by the thermometer is similar to that of the surrounding at the beginning of the experiment and if it differs then note that heat is either gained or lost to the environment.

During the halftime performance for a football game, the color guard is planning a new formation in which seven members stand around a central point and stretch their flag to the person immediately to their left. 10. what is the measure of each exterior angle of the formation?
There are different kinds of angles. The measure of each exterior angle of the formation is 51.4.
What is a exterior angle in math?The term exterior angle is known to be the angle that is found between a side of a polygon and that of an extended adjacent side.
The shape of the halftime is regular heptagon.
Note that a regular heptagon has 7 congruent sides and 7 congruent interior angles.
So the exterior angles are said to be congruent, based on the fact that angles supplementary to congruent angles are regarded as congruent.
So Let take n as the measure of each exterior angle.
7n = 360
n= 360/n
To Solve for n =51.4
Therefore, The measure of each exterior angle of the formation is 51.4.

When the 0.10 m solution of hclo2 is allowed to come to equilibrium, what percent of the acid molecules are ionized?
If 0.10 m solution of hclo2 is allowed to come to equilibrium, the percent of the acid molecules that is ionized is 29%
We have
HClO2 = 0.1 mole = 0.012
HClO + H2O ⇄ ClO₂⁻ + H₂O
Ka = 0.1α x 0.1α / 0.1(1-α)
= 0.1α²/1-α = 0.12
We have to form a quadratic equation from the above
0.1α² = 0.012 - 0.12α
We write the equation to be
0.1α² + 0.012 - 0.12α = 0
To solve the equation above, the quadratic formula calculator was used.
[tex]\frac{-b+-\sqrt{b^2-4ac} }{2}[/tex]
alpha = 0.29
This is 29 percent. Therefore the percentage of ionization is 29%.

drag the labels to identify the events in the generation of an action potential in order and correctly name the refractory periods.
An absolute refractory period occurs during depolarization while the relative refractory period takes place during repolarization.
What is an action potential?An action potential refers to a sudden, quick change in electrical potential (voltage) during the transmission of an impulse (signal) to a receptor, across a cellular membrane.
The order of events in the generation of an action potential include the following:
At -60 mV, graded depolarization transmits an area of excitable membrane to threshold.At +30 mV, voltage-gated sodium channels are opened for sodium ions to move into the cell. As repolarization begins, sodium channels close, voltage-gated potassium channels are opened for potassium ions to move out of the cell. Finally, both sodium and potassium channels return to their normal states as the potassium channels is closed.In conclusion, an absolute refractory period occurs during depolarization while the relative refractory period takes place during repolarization.
