The crew of a garbage truck takes 5 hours to empty all the bins in one neighborhood on pickup day. The city assigned a second garbage truck to this neighborhood. During their training, it took the crew from the second truck 8 hours to empty all the bins. A table showing rate in part per hour, time in hours, and part of bins emptied. The first row shows first truck and has, startfraction 1 over 5 endfraction, t, and startfraction 1 over 5 endfraction times t. The second row shows second truck and has, startfraction 1 over 8 endfraction, t, and startfraction 1 over 8 endfraction times t. When the two crews start working together, what part of all the garbage bins will the first garbage truck empty? 0. 6 0. 5 0. 7 0. 4.

Answers

Answer 1

When the two crews start working together, the part of all the garbage bins that the first garbage truck will empty is; A: 0.6

We are told that the first truck empties all bins in 5 hours. Thus;

Rate of first truck per hour = ¹/₅

Second truck empties all bins in 8 hours. Thus;

Rate of second truck per hour = ¹/₈

If both trucks work together, their rate per hour is;

Combined rate per hour = ¹/₅ + ¹/₈

Combined rate per hour = ¹³/₄₀

Thus, number of hours it will take for both of them to do the whole job, we will solve as;

¹³/₄₀t = 1

where t is the time it will take both of them combined to finish the whole job.

Thus;

t = ⁴⁰/₁₃

The part that the first garbage truck will empty when they both work together = ¹/₅t = ¹/₅ * ⁴⁰/₁₃

⇒ Approximately 0.6

Answers

By differentiating both sides of y = 4x² + 1 with respect to time t, we have

dy/dt = 8x dx/dt

If the x value changes at a rate of +2 units/second (that is, dx/dt = 2) at the moment x = 1, then the y value changes at a rate of

Answers

Answer:

Edge says Fecundity

Explanation:

Fecundity is the biological capacity of an organism to conceive a child - in conjunction with another organism. For this to occur it is necessary that the man and the woman be fertile, that is, they have fertility. A person's fertility is measured by the number of ovules / seeds that can be fertilized. After fertilization, the fetus grows in the gestational process and becomes a baby.

The correct word from the list that best fits the definition of the biological capability to bear children is fecundity. The correct option is E.

What is childbearing?

Women can theoretically become pregnant and give birth from puberty, when they begin having periods, to menopause, when they cease having them. The reproductive years of the average woman last from 12 to 51 years.

The biological ability of one organism to conceive a child in collaboration with another creature is known as fecundity. Both the man and the woman must be fertile, or have fertility, for this to happen.

The quantity of ovules or seeds that can be fertilized is used to determine a person's fertility. The fetus develops during the gestational period after conception to become a baby.

Therefore, the correct option is E. Fecundity.

The probability that a randomly selected customer will wait more than 4 minutes at the deli is given below

The probability that a randomly selected customer will wait more than 4 minutes = [tex]0.4286[/tex]

The waiting time for the customers is uniformly distributed between 0 - 7 minutes

Consider a random variabe X that represents the waiting time of customers and uniformly distributed between 0-7 minutes

Therefore, the density function of X is determined as

[tex]f(x) = \frac{1}{b-a}\\\\f(x) = \frac{1}{7-0}\\\\f(x) = \frac{1}{7}[/tex]

The probability that the customer will wait more than 4minutes,

Place the events that form hurricane-force winds in order.

Answers

Answer: The events that form hurricane-force winds are as follows

1. Tropical disturbance

2. Tropical depression

3. Tropical storm

4. Hurricane.

Explanation:

All of the above-mentioned events happen in chronological order for the hurricane-force winds to occur.

1. Tropical disturbance occurs from the tropics and the subtropics. These are generally 100-300 miles in diameter. It is a tropical weather system of organized conventions. This is the first stage that consists of a loosely organized low-pressure area.

2. Tropical depression is a more organized deep convention and has a closed circulation of sustained winds of less than 39 mph.

3. Tropical storm is the third stage that has sustained winds between 39 - 73 mph.

4. The hurricane is created when the sustained winds finally reach or cross the speed of 74 mph.
