The width of the aquarium is 0.1625 ft.

Step-by-step explanation:

Given,

The length (l) of the aquarium = 2 ft

Height (h) = 1.5 ft

The capacity of water it holds = 3.75 gallons

That means the volume (V) = 3.75 gallon

To find the width(b) of the aquarium.

Formula

So,

V = 3.75×0.13 cube ft

According to the problem,

2×1.5×b = 3.75×0.13

or, b = (3.75×0.13)÷(2×1.5)

or, b = 0.1625 ft

Hence,

The width of the aquarium is 0.1625 ft.

Answer:

Stagflation is the combination of stagnation and inflation. Its simply mean continues increase in inflation while consumer demand for product is stagnant and there is relatively high unemployment

Reason;

Some economist hold that inflation is caused when demand for goods are high and demand for a product can not be controlled where there is no price regulation.

Answer: The reason was because Economists at that time believed that inflation only occurred when the demand for goods was high.

Step-by-step explanation:

Stagflation occurred in the 1970's in the United States under the rule of President Gerald R. Ford. Stagflation is a term used to describe a situation of both stagnation and inflation in the economy. The period was a tough time in the history of America. It occurred just after the tenure of President Johnson who contributed to the crisis through his policy of pumping money into the economy to increase spending without increasing taxes. The resultant effect of this was inflation.

America was also dependent on oil at that time, even though the price of oil was rapidly increasing. The period saw them importing more goods than exporting. Also, jobs were lost. Economists tried to solve the issue but it was difficult because they believed that inflation could only occur when the demand for goods was high.

Answer:

A≈695.29cm²

Step-by-step explanation:

The area of a regular octagon with a perimeter of 96 cm is calculated by first finding the length of one side, then calculating the area of one of the eight isosceles triangles formed within the octagon, and finally multiplying this area by eight to get the total area, which is 384 cm².

To calculate the area of a regular octagon with a given perimeter, we first need to determine the length of one side. Since a regular octagon has equal sides, we can divide the perimeter by 8. In this case, the perimeter is 96 centimeters, so each side of the octagon is 96 cm / 8 = 12 cm.

We know that a regular octagon can be divided into eight identical isosceles triangles. The area of an isosceles triangle can be found by the formula A = (1/2)bh, where b is the base and h is the height.

To find the height of each triangle, we can draw an altitude from the center of the octagon to the base of one of the triangles, which creates two 90-degree triangles.

By using the Pythagorean theorem on one of these right-angled triangles, with the base of each being half the length of an octagon's side (6 cm), and the Pythagorean triple 6-8-10, we can determine the height to be 8 cm. Thus, the area of each triangle is (1/2) * 12 cm * 8 cm = 48 cm².

Finally, since there are eight triangles, the total area of the octagon is 8 * 48 cm² = 384 cm².

Answer:

"It is plausible that 75% of the population takes a daily vitamin because the data shows that a sample proportion of 70% is fairly likely."

Step-by-step explanation:

I took the test!

Based on the dot plot, the majority of the simulated proportions fall between 0.65 and 0.85, which includes the value of 0.75 that Naomi is testing.

Graphs are a not unusual place technique to visually illustrate relationships withinside the statistics. The reason for a graph is to provide statistics that are too severe or complex to be defined appropriately withinside the textual content and in much less space.

Naomi can draw the conclusion from the facts that it is implausible that 75% of the doctor's patients take a daily vitamin.

The dot plot reveals that most simulated proportions are below 75% and only a few are above it.

Further evidence that the sample percentage of 70% is unlikely to have originated from a population with an actual proportion of 75% is provided by the fact that the range of the simulated proportions is rather narrow.

The simulation performed by Naomi shows that the statistic that 75% of people take a vitamin every day is not plausible.

Answer:

$112.50¢

Step-by-step explanation:

please kindly check the attached file for explanation

$112500 would be saved in electricity in the 10,000−hour lifetime of the Fluorescent bulb.

Given that compact fluorescent bulbs use about 25% of the energy of incandescent bulbs.

Hence, For a 100W bulb, the corresponding energy is:

Fluorescent bulb = 25% of 100W = 0.25 * 100 = 25W

Since the charges is $0.15/kW-hour, hence, for 10000 hour lifetime:

Total charges for  Incandescent = 100W * 10000 hour * $0.15/kW-hour = $37500

Total charges for Fluorescent = 25W * 10000 hour * $0.15/kW-hour = $150000

Therefore the money saved in electricity = $150000 - $37500 = $112500

Hence $112500 would be saved in electricity in the 10,000−hour lifetime of the Fluorescent bulb.

Step-by-step explanation:

To work this out you would first divide 1.3 by 100, which gives you 0.013. Then you would add 0.013 to 1, which gives you 1.013. This is because you are finding a percentage increase and so you would convert the percentage to a decimal and add it to 1. Then you would multiply 5949951 by 1.013 to the power of 10. This is because you are finding the percentage increase over a span of 10 years.

1) Divide 1.3 by 100.

[tex]1.3/100=0.013[/tex]

2) Add 0.013 to 1.

[tex]0.013+1=1.013[/tex]

Answer:

First, 32 rounded to the nearest ten is:

30

Step-by-step explanation:

When rounding to the nearest ten, like we did with 32 above, we use the following rules:

A) We round the number up to the nearest ten if the last digit in the number is 5, 6, 7, 8, or 9.

B) We round the number down to the nearest ten if the last digit in the number is 1, 2, 3, or 4.

C) If the last digit is 0, then we do not have to do any rounding, because it is already to the ten.

The theoretical probability of the coin landing heads up is 30%.

The theoretical probability of the coin landing heads up is 30%.

The number of times the coin lands heads up out of the total number of coin flips is called the experimental probability. In this case, the experimental probability is 21/70 = 0.3, or 30%.

The theoretical probability of getting heads on a fair coin is always 50%, but in this specific experiment, the experimental probability varied due to chance. As the number of coin flips increases, the experimental probability should approach the theoretical probability of 50%.

Answer:

NO.

Step-by-step explanation:

In geometry, two figures or objects are congruent if they have the same shape and size, or if one has the same shape and size as the mirror image of the other. So, in other words, 2 shapes  or figures in geometry are congruent if they have the exact same size and shape.

A rectangle has 2 pairs of parallel sides. One pair is longer than the other pair. Therefore, to be congruent, all sides have to be equal, which is a square, not a rectangle. So the answer is NO.

No a rectangle does not have four congruent sides instead it has two pairs of congruent sides.

A rectangle has two pairs of congruent sides that are opposite each other. Therefore, a rectangle does not have four congruent sides, but rather two pairs of congruent sides.

The answer is $10.8 (1,080 cents)

Step-by-step explanation:

First of all, let us calculate the area of the frame:

Area = Length × width = 18 × 3 = 54 in²

We are told that she charges 20 cents per square inch, therefore:

1 in² = 20 cents

∴ 54 in² = 20 × 54 = 1,080 cents.

We know that 100 cents = $1

∴ 1,080 cents = 1/100 × 1,080 = $10.8
