The concentration of hypochlorite ion if 20.00 ml of bleach requires 32.00 ml of 0.500 m hcl to reach the equivalence point is: 0.800 M.
Concentration of hypochlorite ionGiven:
Ca = concentration/molarity of acid=0.500 M
Va = volume of acid= 32.00 cm3
Cb = concentration/molarity of base=?
VB =volume of base= 20.00 cm3
Hence:
Concentration of hypochlorite ion=0.500 × 0 × 1/ 20.00
Concentration of hypochlorite ion=0.800M
Inconclusion the concentration of hypochlorite ion if 20.00 ml of bleach requires 32.00 ml of 0.500 m hcl to reach the equivalence point is: 0.800 M.

The number v of computers infected by a computer virus
The number of hours that the computers will be infected by a computer virus is one hour.
How can computers be infected by viruses?Viruses are known to be some forms of computer worms or trojans that can be spread through a system in a lot of ways.
Its spread can be through networks, discs, email attachments etc. It is one that gives others access to your computer.
The number v of computers infected by a computer virus is given by V(t) = 100e^(4.666t)
So therefore, t is the time in hours.
After 1 hour the number of computer infected v(t=1) = 100*e^(4.666*1)
=100*e^4.666
=100*106.271804

A jar contains five black balls and seven white balls. two balls are drawn sequentially, but the first ball is replaced before the second drawn. the probability of drawing two white balls, given that at least one of the balls is white, is 7/17.
The probability both balls are black, given that the first one is black, is gotten as; ⁵/₁₂
What is the probability of Selection?
By using the probability of an event formula,
There are 5 black balls out of a total of 12 balls, so the probability of obtaining a black on a single draw is ⁵/₁₂, and the probability of obtaining a white is ⁷/₁₂
Since the balls are drawn with replacement, the two draws are independent events.
Use Multiplication and Union Rules to obtain the following probability:
P(F) = P(B, B) + P(B, W)
P(F) = (⁵/₁₂ * ⁵/₁₂) + (⁵/₁₂ * ⁷/₁₂)
P(F) = ⁵/₁₂
Thus, the probability both balls are black, given that the first one is black, is ⁵/₁₂

Consider the net of a triangular prism where each unit on the coordinate plane represents four feet. If a sheet of plywood measures 4 ft x 8 ft, how many sheets of plywood will a carpenter need to build the prism?
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)
