Helia began charging her cell phone battery when it was
30% charged. After 36 minutes, her cell phone battery
was 70% charged. If the cell phone battery charges at a
constant rate, how many more minutes will it take for
her cell phone battery to be exactly 80% charged?

Answers

Answer 1

Answer:

After 9 more minutes, her cell battery will be 80% charged.

Explanation:

Let us try to make an equation here to describe the relation between battery and time.

It is given that the battery charges at a constant rate so we can assume that

battery(\(b\)) ∝ Time(\(t\))

\(\Rightarrow b=kt\)

But at t=0, the battery is already 30% charged so we rewrite the equation as follows:

\(b=kt+30\)           -(1)

Now,

at put t=36 and b=70 in Eqn 1:

We get    \(k=\frac{10}{9}\)

The final eqn is \(b=\frac{10}{9}t +30\)

Put b=80

We get:

\(\Rightarrow80=\frac{10}{9} t+30\\\Rightarrow 50=\frac{10}{9}t\\\\\Rightarrow t=45 \text{min}\)

∴ It will take (45-36)=9 more minutes to reach 80% battery.

Answers

If the length plus the width of the rectangle ABCR is 8, then the perimeter of the shaded region is; (B) 10 + 3π

What is the perimeter of the shaded region?

From the image attached, let us say that;

AR = a

RC = b

The perimeter of a circle is defined as the complete arc length of the periphery of a circle.

The formula for the perimeter of a circle is;

Perimeter = 2πr

However, in the attached image we see that we don't have a full circle but a quarter circle and as such;

Perimeter of quarter circle = ( 2πr ) / 4

We are given that radius; r = 6. Thus;

Perimeter of quarter circle = ( 2π*6 ) / 4 = 3π

From the diagram we can say that;

AS = 6 - a

CT = 6 - b

AC = RB = 6 ( radius )

Now, the perimeter of the shaded region = AS + AC + CT + C(SBT)

Plugging in the relevant values gives;

Perimeter of the shaded region = ( 6 - a ) + 6 + ( 6 - b ) + 3π

Perimeter of the shaded region = 18 - ( a + b ) + 3π

We are told that length + width = 8 . Thus, a + b = 8 and we have;

Perimeter = 18 - 8 + 3π

Perimeter = 10 + 3π

The breaking strengths of cables produced by a certain manufacturer have a standard deviation of 92 pounds. A random sample of 90 newly manufactured cables has a mean breaking strength of 1700 pounds. Based on this sample, find a 95% confidence interval for the true mean breaking strength of all cables produced by this manufacturer. Then give its lower limit and upper limit. Carry your intermediate computations to at least three decimal places. Round your answers to one decimal place

Answers

Answer:

To find the 95% confidence interval for the true mean breaking strength of all cables produced by the manufacturer, we can use the formula:

Confidence Interval = Sample Mean ± (Critical Value * Standard Error)

First, let's calculate the standard error, which is the standard deviation divided by the square root of the sample size:

Standard Error = Standard Deviation / √(Sample Size)

= 92 / √(90)

≈ 9.685

Next, we need to determine the critical value corresponding to a 95% confidence level. Since the sample size is large (n > 30), we can use the z-table. The z-value for a 95% confidence level is approximately 1.96.

Now we can calculate the confidence interval:

Confidence Interval = Sample Mean ± (Critical Value * Standard Error)

= 1700 ± (1.96 * 9.685)

Lower Limit = 1700 - (1.96 * 9.685)

≈ 1679.69

Upper Limit = 1700 + (1.96 * 9.685)

≈ 1720.31

Therefore, the 95% confidence interval for the true mean breaking strength of all cables produced by this manufacturer is approximately (1679.7, 1720.3). The lower limit is 1679.7 pounds, and the upper limit is 1720.3 pounds.

Dan's motorcycle tank holds 6 1/2 gallons of gas. There are 3 5/8 gallons of gas currently in the tank. How much more
gasoline will it take to fill the tank? (Simplify your answer and write it as a mixed number.)

Answers

Answer:

2 7/8

Explanation:

You have to subtract the two numbers to find how much more gas you need to fill the tank.

First, subtract the 6 and 3, getting 3. You then have to subtract the 1/2 and 5/8, meaning the denominators have to be the same to be able to subtract them. So you make the 1/2 to 4/8 by multiplying 4/4 to the numerator and the denominator. You keep the 5/8 because now both fractions have the same denominator. So then you subtract 4/8 and 5/8 which is -1/8.

But we still have the 3, which you can take the -1/8 from, getting 2 and 7/8 because 8/8 is the same as a whole.

Hope this was helpful and let me know if it could be clearer!

The amount of gasoline will it take to fill the tank is 2 7/8.

What is gasoline?

Gasoline is defined as a supplementary fuel that is high in energy and can be used as a form of cash. Many different compounds that include hydrogen and carbon are combined to make gasoline. A typical gasoline mixture typically contains about 150 different hydrocarbons, including butane, pentane, isopentane, and the BTEX compounds.

First, subtract the 6 from the 3 to arrive at 3. The 1/2 and 5/8 must then be subtracted, so the denominators must match for this to be possible. Therefore, you multiply 4/4 by the numerator and denominator to create the 1/2 to 4/8. Since both fractions now have the same denominator, you preserve the 5/8. So you take out 4/8 and 5/8 to get -1/8. However, the 3 remains, from which you can subtract 1/8 to get 2 and 7/8 because 8/8 is a whole that is the same.

Thus, the amount of gasoline will it take to fill the tank is 2 7/8.

The exact same experiment was conducted 15 times. How many times
should the results have been similar for them to be valid?
A. 15
B. 9
C. 8
D. 6

Answers

To consider the results of the 15 experiments valid, they should be similar in at least 8 of the trials . So, option C is the right choice.

To determine the number of times the results should be similar for them to be considered valid, we need to establish a threshold based on the number of experiments conducted. In this case, the experiment was repeated 15 times.

To determine the minimum number of times the results should be similar for validity, we can calculate the majority. We divide the total number of trials by 2 and add 1. In this case, 15 divided by 2 equals 7.5, and adding 1 gives us 8.

Therefore, for the results to be considered valid, they should be similar in at least 8 out of the 15 trials. This threshold ensures that the majority of the experiments produced consistent results, indicating reliability and reproducibility.

Thus, The correct answer is option C.8

A Punnett square may be characterized as a type of table that allows you to determine the expected percentages of different genotypes in the offspring of two parents. It allows the prediction of the percentages of phenotypes in the offspring of a cross from known genotypes.

The potential genotypes of their offspring would not be affected when you switch the locations of the parent genotypes around the Punnett square. This is because the genotypes of the offspring are formed by the random and systematic segregation of their alleles with respect to their genes.

Three reasons why lron cannot be used to make a replacement joint

Answers

Iron's susceptibility to corrosion, poor biocompatibility, and lack of mechanical strength make it unsuitable for use in replacement joints.

First of all, iron is very prone to corrosion when exposed to moisture and oxygen, which might eventually cause the joint to degrade. The joint may become unsuitable for long-term usage in the human body due to corrosion, which can degrade the joint's structural integrity and affect its functionality.

Second, iron has poor biocompatibility, which means that when it comes into touch with live tissues, it may result in unfavourable reactions and tissue responses. This may cause inflammation, immunological reactions, and even the immune system of the body rejecting the joint. Materials with strong biocompatibility are selected to guarantee a successful replacement joint to reduce the risk of problems and enhance patient outcomes.

The mechanical strength needed for a replacement joint is also lacking in iron. In order to endure the loads and forces that joints are subjected to during movement, a material must be strong enough. Iron is a powerful metal, but it might not have the best mechanical qualities, such as high tensile strength, fatigue resistance, and longevity, needed for a joint replacement.

These factors lead to the use of other materials, such as titanium alloys or cobalt-chromium alloys, which provide higher corrosion resistance, biocompatibility, and mechanical qualities suited for long-term usage in the human body.
