a student needs to determine the density of an irregularly shaped object with a mass of . be sure each of your answer entries has the correct number of significant digits.

Answer:

The impulse on an object is equal to the change in momentum of the object. In this case, the ball's initial momentum is 10 kg * 15 m/s = 150 kg m/s. After the collision, the ball's final momentum is -10 kg * 23 m/s = -230 kg m/s.

The change in momentum of the ball is: -230 kg m/s - 150 kg m/s = -80 kg m/s.

So, the impulse on the ball is -80 kg m/s.

Answer:

x = 127°

x = 36

Step-by-step explanation:

The sum of interior angles for the given geometrical figure is calculated with the following formula:

(s-2) × 180

3 × 180 = 540

90 + 143 + 77 + 103 + x = 540

413 + x = 540

x = 127°

The given is a hexagon. The sum of its exterior angles is equal to 360.

80 + 59 + 2x + 59 + 54 + x = 360

252 + 3x = 360

3x = 108

x = 36

The probability of getting someone who is a woman or a heavy drinker is,

0.546 to three decimal places.

None of the above is the correct option.

The Probability in mathematics is possibility of an event in time. In simple words how many times that incident is happening in any given time interval.

Given:

The table lists the drinking habits of a group of college students.

If a student is chosen at random,

then the probability of getting someone who is a woman or a heavy drinker,

=P(woman) + P(heavy drinker) - P(woman and heavy drinker)

= 216/405 + 13/405 - 8/405

= 221/405

= 0.546 to three decimal places.

Therefore, the probability is 0.546.

Operation sign between two of the digits is 96 ÷ 2 × 5 + 8 × 0 - 7 = 8,818

This question uses the Order of Operations (PEMDAS) theory.

The order of operations states that we should work through equations in the following order: Parentheses, Exponents, Multiplication and Division (from left to right), Addition and Subtraction (from left to right).

In this question, the first operation was division (96 ÷ 2), followed by multiplication (48 × 5), then addition (240 + 8), then multiplication (248 × 0), and finally subtraction (0 - 7).

Step 1: 96 ÷ 2 = 48

The slopes I found are (A) equivalent. This means that the slope triangles are (B) similar and no matter what (C) two points I pick on the line the slope will be the (A)same.

The slope is defined as the ratio of the vertical change between two points, the rise, to the horizontal change between the same two points, the run.

Mathematically, the slope is the change in y divided by the change in x. That is:

Slope = y2-y1 / x2-x1

The slope of the line between points A and B:

A (x1 = -5, y1 = -2) and B (x2 = -2, y2 = 0)

Slope = [(0-(-2) )]/ [-2-(-5)] = 2/3

The slope of the line between points B and C:

B (x1 = -2, y1 = 0) and C (x2 = 4, y2 = 4)

Slope = [4-0]/ [4-(-2)] = 4/6 = 2/3

The slope of the line between points A and C:

A (x1 = -5, y1 = -2) and C (x2 = 4, y2 = 4)

Slope = [(4-(-2))]/ [4-(-5)] = 6/9 = 2/3

The required width and length of the given rectangle is 25/12 cm and 63 / 12 cm.

The rectangle is 4 sided geometric shape whose opposites are equal in length and all angles are about 90°.

Here,
Length = 3 1/6 + width

perimeter of the rectangle = 2[length + width]

15 1/3 = 2 [3 1/6 + width + width]
46/3  × 1/2 =  19/6 + 2 width
23 / 3 - 19 / 6 = 2 width
[46 - 19]/ 12 = width
width = 25/12 cm

Now,
Length = 25/12 + 19/6
Length = 63 / 12 cm

The least positive integer N such that the set of 1000 consecutive integers beginning with 1000 N is 282.

Let x² appear before 1000N so:

(x+1)² − x² >1000⟹ x ≥ 500

Let A = [1000N, 1000(N+1)]

So I let x=500

then, x²=250000

, obviously this is impossible since the set has a square already.

So now I need to set some number, k² ≥ 5012 = 0 (mod1000)

So I need to solve the quadratic residue:

Lets see: 500²=250000

and 501²=251001

and 502²=252004

501²=500²+1000+ ∑ (12k−1)

502²=500²+2(1000)+∑ (12k−1)

The number of miles the business person can travel with 110 dollars is 290 miles.

Value Rent-A-Car rents a luxury car at a daily rate of $37.33 plus 25 cents per mile. A business person is allotted $110 for car rental each day.

Therefore, the number of miles the business person can travel on 110 dollars can be calculated as follows;

Using equations,

Therefore,

y = 0.25x + 37.33

where

Therefore, let's find the distance he can travel for 110 dollars.

110 = 0.25x + 37.33

110 - 37.33 = 0.25x

72.67 = 0.25x

x = 72.67 / 0.25

Approximately 68% of housing prices are between a low price of $144,000 and a high price of $160,000.

The Empirical Rule, also known as the 68-95-99.7 rule, states that for a normal distribution, approximately 68% of the data falls within one standard deviation of the mean, 95% falls within two standard deviations, and 99.7% falls within three standard deviations.

Given that the mean of housing prices is $152,000 and the standard deviation is $8,000, we can use the Empirical Rule to determine that approximately 68% of housing prices fall within one standard deviation of the mean. This means that the range of prices that contains 68% of the data is between:

$152,000 - $8,000 = $144,000 and $152,000 + $8,000 = $160,000.

So, approximately 68% of housing prices are between a low price of $144,000 and a high price of $160,000.

We know that the sum of angles of a triangle are 180°

If you don't know how to find the angles of a triangle

We use the formula,

[tex](n-2)X180[/tex]

Where n replicates the sides of a polygon

Applying the sides into the formula we get

[tex](3-2)X180\\1X180\\180[/tex]

Now in order to find x we sum up all the angles into a equation

90°+ 65°+ x - 10° = 180°

145 + x = 180

We then transpose 145 to the Right Hand Side (RHS)

x = 180 - 145

x = 35°

Hence , the value of x is 35°

Answer:

The exterior of a triangle is the sum of two of its interior angles except the one adjacent to it. The angle x is evaluated as 135°.

What is a triangle?

A triangle is a two dimensional shape bounded by three sides. The sum of the interior angles of a triangle is 180°. The longest side of a triangle is always less than the sum of other two sides.

Given that,

There is a triangle shown in the figure with following angles,

∠y = 102°  and ∠Z = 57°.

Angle x is the exterior angle of the given triangle. Use the property of exterior angle to get,

∠x  = ∠B + ∠Z

    = (180° - y) + 57°

    = (180° - 102°) + 57°

    = 135°

                               dP/dt = kP (1- (P/K)) (1-(m/P))   -(1)

where k is a constant and K is the carrying capacity.

Here, K = 10000, m = 800 and k = 0.05

Putting these values in Equation 1 we get,

                      dP/dt = 0.05P (1- (P/10000)) (1-(800/P))

1.) If dP/dt > 0 then P is increasing

As dP/dt > 0

So, 0.05P (1- (P/10000)) (1-(800/P)) > 0

Both ((10000- P)/10000) > 0 and ((P-800)/P) > 0

=> P < 10000 and P > 800

So, for  800 < P < 10000, the population will increase.

2.)  If dP/dt < 0 then P is decreasing

As dP/dt < 0

So, 0.05P (1- (P/10000)) (1-(800/P)) < 0

Both ((10000- P)/10000) > 0 and ((P-800)/P) > 0
