Four whole numbers are each rounded to the nearest 10
The sum of the four rounded numbers is 90
What is the maximum possible sum of the original four numbers?

Answers

Answer 1

The maximum amount of the original four numbers is 110.

What is the whole number?

A whole number is simply any positive number that does not include a fractional or decimal part. This means that, for example, the numbers 0, 1, 2, 3, 4, 5, 6, and 7 are all whole numbers.

Four whole numbers are each rounded to the nearest 10, which means each number can go +5 or -5.

The sum of the rounded numbers is 90, the maximum amount of the original four numbers is if +5 are added with each 4 original number.

So each number would have an extra +5.

And then the maximum number is 90 + (5 x 4) is equal to 110.

Or if the rounded-up no. were 10, 20, 30, 30.

The sum of these numbers is 90.

They can go up to 15,25,35,35.

So the sum of this is 110.

Hence, the maximum possible sum of the original four numbers is 110.

A sector with central angle theta is cut froma circle of radius 10 inches and the edges of the secotr are brought toegether to ormnr a cone find the amgnitude of theta such that thte volume of the conbe is a maximum

Answers

So, the maximum volume of the cone is approximately 1047.19 cubic inches.

The volume of a cone is given by the formula V = (1/3) * pi * r^2 * h, where r is the radius of the base and h is the height of the cone. In this case, the height of the cone is the radius of the circle, which is 10 inches, and the radius of the base is half the length of the circumference of the sector, which is (theta/360) * 2 * pi * 10 inches.

We want to find the value of theta that maximizes the volume of the cone. We can do this by taking the derivative of the volume formula with respect to theta, setting it equal to 0, and solving for theta.

V = (1/3) * pi * r^2 * h

= (1/3) * pi * ((theta/360) * 2 * pi * 10)^2 * 10

= (1/3) * pi * (theta/36)^2 * 100

dV/dtheta = (2/3) * pi * (theta/36) * (100/36)

= (2/3) * pi * theta/36

Setting dV/dtheta = 0 and solving for theta, we get theta = 0.

Since the magnitude of theta must be positive, the maximum volume occurs when theta = 0, which means that the entire circle is used to form the cone. The maximum volume of the cone is then

V = (1/3) * pi * r^2 * h

= (1/3) * pi * (10)^2 * 10

= (1/3) * pi * 100 * 10

= (1/3) * pi * 1000

= approximately 1047.19 cubic inches

So, the maximum volume of the cone is approximately 1047.19 cubic inches.

Find the interest rate for a principal of $5305 and charged $39534 in interest for 20 years

Answers

Answer:

37.237%

Step-by-step explanation:

Use the Formula I = P x R x T

P = Principal amount (the beginning balance).

R = Interest rate (usually per year, expressed as a decimal).

T = Number of time periods (generally one-year time periods).

Plug in the values

I = 5305 x R x 20

Solve for R by dividing 20 by 5305

I=5305 x R x 20

20 / 5305 = 0.0037

Answer: 10.56 or 10.6 %

Step-by-step explanation:

5305 x x^20 = 39534

39534/5305 = x^20

20√39534/5305 = x

x = 1.1056

1.1056 x 100 = 110.56

110.56 - 100 = 10.56 or 10.6

Solve g(x) = 10, if g(x) = 2/x+1​

Answers

Answer:

x = -0.8.

Step-by-step explanation:

To solve for x in the equation g(x) = 10, we need to find the value of x that makes g(x) equal to 10. Since we are given that g(x) = 2/x+1, we can substitute this expression for g(x) in the equation g(x) = 10 to get:

2/x+1 = 10

Next, we can multiply both sides of the equation by x+1 to get rid of the fraction on the left side:

2 = 10 * (x+1)

This simplifies to 2 = 10x + 10, which we can rearrange to get 2 - 10 = 10x. Subtracting 10 from both sides gives us -8 = 10x. Finally, dividing both sides by 10 gives us the solution: x = -0.8.

Therefore, the value of x that makes g(x) equal to 10 is x = -0.8.

When solving the following equations, multiply the first and second equation by a constant in order to eliminate the y terms.

2x + 2y = 7

6x + 3y = -2

What are the constants of both equations?

Answers

Answer:

multipliers: 3, 2 for subtraction; or 3, -2 for addition.solution: (x, y) = (-4 1/6, 7 2/3)

Step-by-step explanation:

You want to solve the given system of equations by eliminating the y-term. You also want to know what constants are used in the process.

Elimination

The y-term can be eliminated from these equations by combining them in such a way as to may the coefficient of y be zero. This can be done an infinite number of ways.

One way that works reasonably well is to identify the coefficients of y, and multiply each equation by the y-coefficient in the other equation. The resulting equations can be subtracted one from the other to eliminate the y-terms, which now have identical coefficients. You can choose the equation with the smaller x-coefficient to subtract from the other one.

Application

The y-term coefficients are 2 and 3.

Multiply the first equation by 3, and the second by 2.

  3 × (2x +2y) = 3 × 7   ⇒   6x +6y = 21

  2 × (6x +3y) = 2 × (-2)   ⇒   12x +6y = -4

The x-coefficients are 6 and 12. We choose to subtract the first equation (with x-coefficient 6) from the second equation:

  (12x +6y) -(6x +6y) = (-4) -(21)

  6x = -25 . . . . . . . . simplified

  x = -25/6 = -4 1/6 . . . . . divide by 6

Substituting for x in the first equation, we have ...

  2(-25/6) +2y = 7

  2y = 7 +25/3 . . . . . add 25/3

  2y = 46/3 . . . . . . . .combine terms

  y = 23/3 = 7 2/3 . . . . divide by 2

The solution to the equations is (x, y) = (-4 1/6, 7 2/3).

Check

Since these numbers are not integers, we choose to check them in the original equations. We used the first equation to find y, so we'll use the second equation for checking.

   6(-4 1/6) +3(7 2/3) = -25 +23 = -2 . . . . . . as required

__

Additional comment

If you solve these by addition, rather than subtraction, you want to choose multipliers that result in opposite coefficients, so they add to zero. Essentially, you use the opposite coefficients, as described above, but you negate one of them.

Above, we chose the subtraction in a way that resulted in the x-coefficient being positive. If you arbitrarily choose the signs of the multipliers (always negating the second one, for example), the combined equations may make the x-coefficient negative. That works, too, but may require more mental effort to deal with the minus sign.

Of course, you can use the x-coefficients and eliminate the x-terms.

Or, you can use a single multiplier that corresponds to the ratio of the coefficients. For example the ratio of the 2nd y-coefficient to the first one is 3/2. Multiplying the first equation by this will give the y-term a coefficient of 3, matching the y-coefficient in the 2nd equation. Then the subtraction can proceed as already described.

  (6x +3y) -3/2(2x +2y) = (-2) -3/2(7)

  3x = -25/2 . . . . . simplified; y is gone.

assume that the maximum speed your car will go is a linear function of the steepness of the hill is going up or down. SUppose the car can go a maximum of 55 mph up a 5 hill and a maximum of 104 down a 2 hill

Answers

The maximum speed of the linear function is y = -7x + 90

Assume that the maximum speed your car will go is a linear function of the steepness of the hill is going up or down?

a. we have two points connecting (speed, degree) are (+5,55) and (-2,104) representing (x₁ , y₁) and (x₂, y₂)

Slope = (y₂ - y₁) / (x₂ - x₁)

slope = (104-55) / (-2-5) = 49/-7 = -7 mph/1°

speed = slope x (degree) + b

Solve 'b':

55 = -7 x (5) + b

55 = -35 + b

b = 55 + 35

b = 90

y₁ = -7x₁ + 90

b) What does the speed-intercept equal and what does it represent?  

The speed is 90 mph when there is no hill.

c ) What does the degree of steepness-intercept and what does it represent?

Up the hill, the steepness is roughly 12.9 degrees at its maximum. Whenever there is a slope, the car will not move.

d) Interpret the slope in words.

The speed drops by 7 mph for every 1 degree that the hill's steepness increases.

e) If your top speed is 83 mph, how steep is the hill?  Be sure to include whether the direction is up or down.

83 = -7 x + 90

83 -90 = -7x

-7 = -7x

x = 1° up the hill

f) How fast could you go down a 7º hill?

y = -7 (-7) + 90

y = 139 mph

what is the rate of change (slope) of the distance in feet below sea level with respect to time that the submarine traveled? place your answer in the box:

Answers

The rate of change (slope) of the distance in feet below sea level with respect to time that the submarine traveled is 11 feet .

Is the rate of change and slope the same thing?

Slope and rate of change are the same thing. The difference is just semantics of the situation.

Typically we use the word “slope” when we are referring to a graph, and we use the phrase “rate of change” when we are referring to a table or a situation in real life.

But that’s not absolute. We can count the slope on a graph, but there’s also a “slope formula” for use when you have two coordinate points or two data points — even though you are not creating a graph.

What do you call "the rate of change of slope"?

It is the derivative of of the slope, or the second derivative of the original function.

For example, if you plot position verses time, the slope between two points(change in position per change in time) is the velocity. This is the first derivative.

Take any two points ( 0 , 380 ) and ( 15 , 545 )

slope m = 545 - 380 / 15 - 0

= 165 / 15

= 33 / 3

= 11 / 1

= 11 feet

Hence the slope m is 11 feet .

The fraction 1¹/₂ + ⁵/₇ = 2³/₁₄

What are fractions?

Fractions are numbers written in the form a/b where a and b are integers and b ≠ 0.

How to find what 1¹/₂ + ⁵/₇?

Since we have the fractions 1¹/₂ and  ⁵/₇ and we want to compute the sum

1¹/₂ + ⁵/₇, we re-write the first fraction as an improper fraction.

So, 1¹/₂ = ³/₂

Now, re-writting the equation, we have

³/₂ + ⁵/₇

To find the sum, wetake the L.C.M of both numbers which 2 × 7 = 14.

So, we make both denominators equal to the L.C.M.

So,  

³/₂ × ⁷/₇ + ⁵/₇ × ²/₂ = ²¹/₁₄ + ¹⁰/₁₄

= (21 + 10)/14

= 31/14

= (28 + 3)/14

= 28/14 + 3/14

= 2 + 3/14

= 2³/₁₄

A cruise ship traveled to Madagascar and
back. On the trip there it traveled 12 km/h
and on the return trip it went 18 km/h.
How long did the trip there take if the
return trip took six hours?
A) 12 hours
C) 9 hours
B) 10 hours
D) 7 hours

Answers

To find the time it took the cruise ship to travel to Madagascar, we need to use the formula for distance, which is distance = speed x time. We are given the distance and the speed of the ship on the trip there, so we can solve for the time by dividing the distance by the speed:

time = distance / speed

We are told that the distance of the trip there was the same as the distance of the return trip, which took 6 hours. We are also told that the ship traveled 12 km/h on the trip there, so the distance of the trip there was 12 km/h x 6 h = 72 km.

Now we can plug this information into the formula to solve for the time:

time = 72 km / 12 km/h = <<72/12=6>>6 hours

Therefore, it took the cruise ship 6 hours to travel to Madagascar. The correct answer is therefore (A) 12 hours.

What is the Sum of Angles on a Straight Line?

The sum of all the angles on a straight line is equal to 180 degrees.

To find the size of the smallest angle, find the value of a by creating the equation below:

(2a + 62) + (54 - a) + (5a - 20) = 180

Open the parentheses:

2a + 62 + 54 - a + 5a - 20 = 180

How to calculate prevalence and incidence asthma?

Prevalence is the formula to determine the rate of some case based on population. This can be calculated by divide the case by the population.

Incidence rate is same as prevalence in some factor except it only calculate time range and for this case it have same formula which is we can calculate incidence rate by divide the case by the population.

So, for January 1, 2019 is

Prevalence = 1,098 / 19,800

= 0.055

For September 1, 2019 is

Prevalence = (1,098 +  new 495) / 19,800

= 1,593 / 19,800

= 0.080

For incidence of asthma between January 1 and September 1 is

Incidence = 495 / 19,800

= 0.025

For 2018 because we are not provided with data for that year so it is impossible to calculate it.

Thus, the prevalence in January 1 is 0.055, September 1 is 0.080, and incidence between January 1 and September 1 is 0.025, and also there is not possible to calculate asthma incidence rat for the year 2018.

Step-by-step explanation:

You have an observer 337 m from a skyscraper who measures the angle of elevation from a point 1.75 m above the ground to be 19°. You want to know the height of the skyscraper.

Tangent

The tangent relation tells you ...

  Tan = Opposite/Adjacent

Solving for the side opposite the angle, we get ...

  Opposite = Adjacent · Tan

Application

In this scenario, the height of the building above the eye height is ...

  height above eyes = (337 m)(tan 19°) = 116.038 m

Then the height of the building is ...

  skyscraper height = eye height + height above eyes

  skyscraper height = 1.75 m + 116.038 m = 117.788 m

The height of the skyscraper is about 117.79 meters.

Find the greatest possible error :19oz

Answers

Answer:

  0.5 oz

Step-by-step explanation:

You want the greatest possible error associated with the measurement 19 oz.

Measurement error

The possible error is generally considered to be half the place value of least-significant digit. Here, the least significant digit has a place value of units, so the greatest error is 1/2 unit, or 0.5 ounces.

__

Additional comment

We know that values of 18.5 oz up to 19.4999... oz will round to 19 oz. That is why the greatest error is considered to be 0.5 oz.

In practice, there can be some difficulty associated with knowing that a value is 18.5 instead of 18.49. Hence real-world error may actually be slightly larger than 0.5 oz. In math, we ignore that case.

Algebraically find the x-coordinates where the line y=2x+3 intersects the circle (x-3)^2 + (y+6)= 50

Answers

The x-coordinates where the line y = 2x + 3 intersects the circle is equal to -2 and -4.

What is the equation of a circle?

Mathematically, the standard form of the equation of a circle is represented by this mathematical expression;

(x - h)² + (y - k)² = r²  

Where:

h and k represents the coordinates at the center of a circle.r represents the radius of a circle.

From the information provided, we have the following system of equations:

(x - 3)² + (y + 6)² = 50      ......equation 1.

y = 2x + 3              .............equation 2.

In order to determine the x-coordinates at the point of intersection, we would substitute the equation 2 into equation 1:

(x - 3)² + (2x + 3 + 6)² = 50

(x - 3)² + (2x + 9)² = 50

x² - 6x + 9 + 4x² + 36x + 81 - 50 = 0

5x² + 30x + 40 = 0

x² + 6x + 8 = 0

x² + 6x + 9 = 1

(x + 3)² = 1

Taking the square of both sides of the equation, we have;

x + 3 = ±1

x = ±1 - 3

x = -2 and -4
