A circular coaster has a diameter of 5 inches. What is its area? write your answer using π.

Answers

Answer 1

Answer:

Step-by-step explanation:

Diameter=5 inches

Area= π[tex]r^{2}[/tex]

r is the radius of coaster.

Radius=diameter/2

Substitute the value of D:

r=5/2

Now

Area=π [tex]\frac{5}{2} ^{2}[/tex]

Area=π([tex]\frac{25}{2}[/tex])

Area=12.5π sq.inches

The sum of two numbers is 64 Twice the larger number plus five times the smaller number is 20. Find the two numbers​

Answers

Answer:

The numbers are 100 and -36.

Step-by-step explanation:

Let x be the larger number

64 - x be the smaller number

x + ( 64 - x ) = 64

2x + 5 ( 64-x ) = 20

2x + 320 - 5x = 20

-3x = -300

x = 100

64 - 100 = -36

A radar gun measured the speed of a baseball at 92 miles per hour.

If the baseball was actually going 90.3 miles per hour, what was the percent error in this measurement?

Answers

Answer:

subtract the actual measurement from the initial measurement

ie. 92-90.3 =1.7 %

You can calculate the error and then measure how much percent of the real value, the error came.

The percent error in the considered measurement is of approx 1.88%

How to calculate the percent error?

Suppose the actual value and the estimated values after the measurement are obtained. Then we have:

Error = Actual value - Estimated value

To calculate percent error, we will measure how much percent of actual value, the error is, in the estimated value.

[tex]\text{Percent error} = |\dfrac{Error}{\text{Actual value}}| \times 100 = |\dfrac{\text{(Actual value - Estimated value)} }{\text{Actual value}}| \times 100[/tex]

Sine in the given condition, we have:

Actual measurement = 90.3 miles per hourEstimated measurement = 92 miles per hour

Thus, we have

Error = 90.3 - 92 = -1.7 miles per hour

Thus, the percent error is calculated as:

[tex]\text{Percent error} = |\dfrac{-1.7 }{90.3}|\times 100 = \dfrac{1.7 \times 100}{90.3} = \dfrac{170}{90.3} \approx 1.88\%[/tex]

Thus,

The percent error in the considered measurement is of approx 1.88%

a box with a square base is taller than it is wide. in order to send the box through the US mail, the height of the box and the perimeter of the base cna sum to no more than 108 in. what is the maximum colume for such a box

Answers

The given box has the shape of a cuboid, since its height is greater than its width. Thus, the maximum volume for such box is 11200 [tex]in^{3}[/tex].

The volume of an object is a measure of it containing capacity. Since the given box has a taller height than its width, then it has the shape of a cuboid. The volume of a cuboid is given as:

volume = length x width x height

            = area x height

Given that the sum of the perimeter of its base and its height is not more than 108 inches, we can say; let the sides of the square base be represented by l and its height by h.

Then;

4l + h = 108

Therefore, maximum volume for the box can be attained when l = 20 inches and h = 28 inches.

So that;

4(20) + 28 = 80 + 28

                 = 108 inches

Thus;

maximum volume = area of the square base x height

                        = 400 x 28

maximum volume = 11200 [tex]in^{3}[/tex]

The maximum volume for such a box would be 11200 [tex]in^{3}[/tex].

1 minute is equal to 60 seconds. How many seconds are in 4 minutes, 14 seconds?

Answers

Answer:

254 seconds

Step-by-step explanation:

If 1 minute = 60 second

then

60 x 4 = 240 second

then add 14

240 + 14 = 254

Therefore, there are 254 second in 4 minutes and 14 seconds

Because 1 minute = 6 seconds, we will multiply 60 seconds x 4 because we add 60 to itself 4 times to convert minutes to seconds. We will then add 14 seconds to that in order to get the total time in seconds

60•4+14

240+14 = 254

Therefore, there is 254 seconds total.

Which relation is a function

Answers

Answer:

The 1st one on the right is a function

Answer:

Parabola Graph (top-right)

Step-by-step explanation:

A graph represents a function given that none of the x-coordinates have more than one corresponding y-coordinates. Consequently, if a graph contains two or more different points with the same x-coordinate, then that graph does not represent a function.  

An easier way of finding out whether a graph represents a function is through the vertical line test. In order to perform the vertical-line test, imagine dragging a ruler held vertically across the graph from left to right. A graph is a function if the edge of the ruler crosses the graph only once for every x -value.  

Out of all the given options, the graph of an upward-facing parabola represents a function (top-right graph), as each vertical line contains only one point. Please see the attachment, where I performed the vertical line test.
