Two trains simultaneously left points M and N and headed toward each other. The distance between point M and N is 380mi. The speed of the train, which started, from point N was 5 mph faster than the speed of the other train. In two hours after the departure the distance between the trains was 30 mi. What is the speed of each train?

Answer:

56.52mm

Step-by-step explanation:

If the diameter is 18, the radius is 9.

The formula for circumference is c=2πr

so, 2*3.14*9=56.52

56.52mm

The total cost of the camera with sales tax included is $976.68

The listed  price of the camera = $891.95

The sales tax rate = 9.5%

The amount of tax = The listed  price of camera × (The sales tax rate / 100)

Substitute the values in the equation

The amount tax = 722.95 × (9.5 / 100)

Divide the terms first

= 891.95 × 0.095

Multiply the terms

= $84.735

The cost of the camera including tax = The listed  price of camera + The amount of tax

Substitute the values in the equation

= 891.95 +84.735

= $976.68

Hence, the total cost of the camera with sales tax included is $976.68

Answer:

Add 3

The pattern provided can be obtained by adding a constant number to the previous term. The common number is 3 because each term is 3 more than the previous term.

Therefore, you can add 3 to the previous term to get the next term.

Accοrding the given questiοn 0.16 is 0.4 Percentage οr % οf 40

A percentage is a number οr ratiο that can be expressed as a fractiοn οf 100 in mathematics. If we need tο calculate a percentage οf a number, multiply it by 100 and divide it by the tοtal. Sο, a part per hundred is what the percentage refers tο. Percent means fοr every 100. The symbοl "%" is used tο denοte it.

Percentages have nο dimensiοn. Hence it is called a dimensiοnless number. If we say, 50% οf a number, then it means 50 per cent οf its whοle.

0.4% is equivalent tο 0.4/100 = 0.004 as a decimal.

Tο find οut what number (a) is 0.4% οf 40, we can use the fοllοwing fοrmula:

a = 0.004 x 40

a = 0.16

Therefοre, 0.4% οf 40 is 0.16.

The slope-intercept form of this table is y = 3x - 10.

In Mathematics, the point-slope form of any straight line can be determined by using the following mathematical expression:

[tex]y - y_1 = \frac{(y_2- y_1)}{(x_2 - x_1)}(x - x_1)[/tex] or y - y₁ = m(x - x₁)

Where:

At point (25, 65), an equation of this line in slope-intercept form can be calculated by using the point-slope form:

[tex]y - y_1 = \frac{(y_2- y_1)}{(x_2 - x_1)}(x - x_1)[/tex]

[tex]y - 65 = \frac{(68- 65)}{(26 - 25)}(x - 25)[/tex]

y - 65 = 3(x - 25)

y = 3x - 75 + 65

y = 3x - 10.

In this context, we can reasonably infer and logically deduce that an equation of the line that represents this table in slope-intercept form is y = 3x - 10.

The length of JL can be found by subtracting the length of ML from the sum of LK and LN. Therefore, JL = 28 + 16 - 12 = 32.

To find the length of JL, first we can add the lengths of LK and LN. LK = 28 and LN = 16, so 28 + 16 = 44. Then, we can subtract the length of ML from the sum of LK and LN. ML = 12, so 44 - 12 = 32. Therefore, JL = 32.

This can be done by visualizing the diagram. The length of JL can be found by adding the lengths of LK and LN, which can be seen as the two sides of the right triangle that form the line MN. Then, the length of ML can be subtracted from the sum of LK and LN to get the length of JL. This is because the length of JL is equal to the length of LK plus the length of LN minus the length of ML.

"To solve this problem, we can use the Law of Cosines. Let's call the distance the pilot travels before the course correction d1 and the distance she travels after the course correction d2. We want to find the distance between her starting position and ending position, which we can call D.

First, let's find d1:

d1 = (720 mph) * (90 min / 60 min) = 1080 miles

Next, let's find d2:

d2 = (720 mph) * (100 min / 60 min) = 1200 miles

Now we can use the Law of Cosines:

D² = d1² + d2² - 2d1d2*cos(20°)

D² = 1080² + 1200² - 210801200*cos(20°)

D ≈ 1169 miles

Therefore, the pilot is approximately 1169 miles from her starting position." (ChatGPT, 2023)

Therefore , the solution of the given problem of probability comes out to be there is a 0.0084 percent chance that a raw number chosen at random will be higher than 96.

The primary goal of the designs inside a practice known as criteria is the evaluation of the likelihood that a claim is accurate or that a specific event will occur. Any number between 0 and 1 can be used to represent chance, with 1 usually representing a range level of certainty and 0 typically representing possibility. A probability diagram shows the chance that a specific event will occur. Just the digits 0% and approximately 100% make up the decimal 1, 0, and 0.

Here,

To resolve this issue, we can use the conventional normal distribution. First, we must standardise the 96 number using the following equation:

=> z = (x - μ) / σ

where the mean is, the standard deviation is, and x is the number we're interested in. When we enter the numbers, we obtain:

=> z = (96 - 85) / 4.6 = 2.3913

The area to the right of z = 2.3913 can then be determined using a calculator or a conventional normal distribution table.

The area to the right of 2.39, according to a standard normal distribution chart, is 0.0084. (rounded to four decimal places).

As a result, there is a 0.0084 percent chance that a raw number chosen at random will be higher than 96.

Answer: Jalen wants the post to be perpendicular to the ground, which means the angle between the post and the ground should be 90 degrees. If the protractor showed the angle to be 82 degrees, then the post is leaning towards the ground. To make the post perpendicular, the angle needs to be decreased. Jalen incorrectly concluded that he needed to increase the angle by 12 degrees, which would make the angle 94 degrees, still not perpendicular.

To make the post perpendicular, Jalen needs to decrease the angle by 8 degrees (90 - 82 = 8). Therefore, the correct answer is D: The angle needs to be increased by 8 degrees to get to a 90 degree angle.

Second option is correct.

Step-by-step explanation:

We have been given that p varies jointly with r and s.

Thus, we can write it mathematically as

[tex]p=krs[/tex]

Here, k is the constant of variation.

Now, we have to find the value of k.

Divide the above equation by rs

[tex]\dfrac{p}{r \ s}=\dfrac{kr\ s}{rs}[/tex]

[tex]k=\dfrac{p}{r s}[/tex]

Hence, the value of k is [tex]k=\dfrac{p}{r s}[/tex]

Answer:

Step-by-step explanation:

Note that where the above conditions exists with regard to the geometric ratios, the sum of the antecedents is approximately 445.31.

Let the three continuous geometric ratios be a, ar, and ar^2, where a is the first term and r is the common ratio. Then the equality can be written as:

a/ar + ar/ar² + ar² = 3/4

Simplifying this equation, we get:

1/r + r + r² = 3/4

Multiplying both sides by 4r², we get:

4r + 4r³ + 4r⁴ = 3r²

Rearranging, we get:

4r⁴ + 3r² - 4r = 0

We can factor this equation as:

r(4r³ - 4r² + 3) = 0

Since r cannot be zero, we must solve the cubic equation:

4r³ - 4r² + 3 = 0

Using a numerical method or a computer program, we can find that one real root of this equation is approximately 0.8202.

Now that we know the value of r, we can use the difference between the largest and minor consequent to find the value of a. The largest consequent is ar², and the minor consequent is a, so we have:

ar² - a = 120

Substituting r = 0.8202, we get:

a(0.8202)² - a = 120

Simplifying, we get:

a = 120 / (0.6721)

a ≈ 178.63

Finally, we can calculate the sum of the antecedents:

a + ar + ar² = 178.63 + (178.63)(0.8202) + (178.63)(0.8202)²

Summing these terms, we get:

a + ar + ar² ≈ 445.31

Therefore, the sum of the antecedents is approximately 445.31

how about after 1 year?  well, we simply set t = 1, so (250)(0.025)(1) = 6.25.

would the interest for t = 2 be the same as for t = 1, if t = 2 is calculated, anyhow, the wording is a bit poor, let me reword it.

after the 1st year, she has an accumulated amount of 250 + 6.25 = 256.25.

well, hell no, because (250)(0.025)(2) using the inital amount

is not the same as (256.25)(0.025)(2).

The numeric value of the expression is given as follows:

[f(x + h) - f(x)]/h = 5h + 10x + 6.

To obtain the numeric value of a function or of an expression, we substitute each instance of the variable in the function or in the expression by the value at which we want to find the numeric value.

The function for this problem is given as follows:

f(x) = 5x² - 6x + 1.

The numeric value at x = x + h is given as follows:

f(x + h) = 5(x + h)² - 6(x + h) + 1

f(x + h) = 5(x² + 2xh + h²) - 6x + 6h + 1

f(x + h) = 5x² + 10xh + 5h² - 6x + 6h + 1

Hence:

f(x + h) - f(x) = 5x² + 10xh + 5h² - 6x + 6h + 1 - 5x² + 6x + 1

f(x + h) - f(x) = 10xh + 5h² + 6h

f(x + h) - f(x) = h(5h + 10x + 6).

Simplifying by h, we have that:
