I need to know this I don’t understand and it is last one

Answer:

Step-by-step explanation:

The diagram lacks the appropriate figure. Find the figure attached. If the line I is perpendicular to m, this means that the sum of the given angles will be equal to 90° as shown;

(3x+5)° + 37° = 90°

open the parenthesis

3x+5 + 37° = 90°

3x+42 = 90

subtract 42 from both sides of the equation

3x+42-42 = 90-42

3x = 48

Divide both sides of the resulting equation by 3;

3x/3 = 48/3

x = 16

Hence the value of x is 16°

Answer:

1152 hours

Step-by-step explanation:

It doesn’t mention that it has AM or PM, so we’re assuming that it’s just the same time, regardless if the clocks actually shows the wrong time in am/pm-wise.

So, if it gains 5 minutes every 8 hours, we have to make see how many 5-minutes that we need to make 12 hours. 12 hours is equal to 720 minutes, so 720/5=144. Since it asks how many hours we need for it to become the same time again, we need to add the fact that it only adds 5 minutes every 8 hours. Henceforth, we need to multiply our answer (144) by 8 hours. 144*8=1152. Your answer is 1152 hours.

The shortest interval of time after which the clock will show the correct time again is 144 hours.

Given that a certain analog clock runs fast and gains 5 minutes every 8 hours, and it was set to show the correct time, to determine what is the shortest interval of time after which the clock will show the correct time again the following calculation must be done:

A clock has a duration of 12 hours, that is, it makes a full turn in that time. Thus, the advance time must be 12 hours for the marked time to be correct.

Therefore, the shortest interval of time after which the clock will show the correct time again is 144 hours.

Answer:

The ratio is   k  =   2.76 pounds /  foot

Step-by-step explanation:

From the question we are told that

   For  1 m  height  =>  4.10 kg mass

generally  1 meter = 3.28084 feet  

Also

  1 kg  = 2.20462 pound

  4.10 kg  =  x pounds

So

      [tex]x = \frac{4.10 * 2.20462}{1 }[/tex]

=>    [tex]x = 9.04 \ pounds[/tex]

So

        9.04 pounds  = 3.28084  feet  

         z pounds  =  1 foot

So  

       [tex]z = \frac{ 9.04 * 1 }{ 3.28084}[/tex]

=>   z = 2.76 pounds

So the ratio is in pounds per foot is

      k  =   2.76 pounds /  foot

Answer: y=-4x+7

Step-by-step explanation:

To find a parallel line, we know that the slope must be the same because parallel lines NEVER touch or cross. All we have to do is use the given point to find the y-intercept.

y=-4x+b

7=-4(0)+b            [multiply]

b=7

Now, we know that the final equation is y=-4x+7.

Answer:

The answer is

Step-by-step explanation:

Equation of a line is y = mx + c

where

m is the slope

c is the y intercept

To find the equation of the parallel line we must first find the slope of the original line

The original line is y = - 4x + 2

Comparing with the general equation above

Slope / m = - 4

Since the lines are parallel their slope are also the same

Slope of parallel line = - 4

So the equation of the line using point (0,7) and slope - 4 is

[tex]y - 7 = - 4(x - 0) \\ y - 7 = - 4x[/tex]

We have the final answer as

Answer:

$127,618,279.99

Step-by-step explanation:

Adjusted for inflation, $163,882,660.00 in 1993 is equal to $127,618,279.99 in 1987.

Annual inflation over this period was 4.26%.

Answer:

a) 27.6%

b) 68.6%

c) 81.6%

d) 59.0%

e) 40.2%

Step-by-step explanation:

Let's say R = recycles, and B = believes bags should be banned.

We're given the following probabilities:

P(B) = 0.54

P(R and B) = 0.41

P(R given NOT B) = 0.60

a. Use conditional probability:

P(R given NOT B) = P(R and NOT B) / P(NOT B)

0.60 = P(R and NOT B) / (1 − 0.54)

P(R and NOT B) = 0.276

b. P(R) = P(R and B) + P(R and NOT B)

P(R) = 0.41 + 0.276

P(R) = 0.686

c. P(R or B) = P(R) + P(B) − P(R and B)

P(R or B) = 0.686 + 0.54 − 0.41

P(R or B) = 0.816

d. P(NOT R or NOT B) = 1 − P(R and B)

P(NOT R or NOT B) = 1 − 0.41

P(NOT R or NOT B) = 0.59

e. P(NOT B given R) = P(NOT B and R) / P(R)

P(NOT B given R) = 0.276 / 0.686

P(NOT B given R) = 0.402

Using conditional probability, it is found that:

a) 0.276 = 27.6% probability that the adult recycles and does not believe that plastic, noncompostable shopping bags should be banned.

b) 0.686 = 68.6% probability that the adult does recycle.

c) 0.816 = 81.6% probability that the adult does recycle or does believe that plastic, noncompostable shopping bags should be banned.

d) 0.59 = 59% probability that the adult does not recycle or does not believe that plastic, noncompostable shopping bags should be banned.

e) 0.402 = 40.2% probability that the adult does not believe that plastic, noncompostable shopping bags should be banned given that the adult does recycle.

-----------------------------------

Conditional probability:

[tex]P(B|A) = \frac{P(A \cap B)}{P(A)}[/tex]  

Item a:

Event A: Bags should not be banned.

Event B: Recycle.

[tex]P(B|A) = \frac{P(A \cap B)}{P(A)}[/tex]

[tex]P(A \cap B) = P(A)P(B|A) = 0.46(0.6) = 0.276[/tex]

0.276 = 27.6% probability that the adult recycles and does not believe that plastic, noncompostable shopping bags should be banned.

Item b:

First, we have to find the proportion that recycle, given that they believe bags should be banned. Thus:

54% of adults surveyed believed that plastic, noncompostable shopping bags should be banned.

Thus [tex]P(A) = 0.54[/tex].

41% of adults regularly recycle aluminum cans and believe that plastic, noncompostable shopping bags should be banned.

Thus P(A \cap B) = 0.41[/tex]

Then

[tex]P(B|A) = \frac{P(A \cap B)}{P(A)} = \frac{0.41}{0.54} = 0.7592[/tex]

The probability that recycle is the sum of:

Then:

[tex]p = 0.6(0.46) + 0.7592(0.54) = 0.686[/tex]

0.686 = 68.6% probability that the adult does recycle.

Item c:

Sum of:

Thus:

[tex]p = 0.686 + 0.2408(0.54) = 0.816[/tex]

0.816 = 81.6% probability that the adult does recycle or does believe that plastic, noncompostable shopping bags should be banned.

Item d:

Sum of:

Thus:

[tex]p = 0.314 + 0.276 = 0.59[/tex]

0.59 = 59% probability that the adult does not recycle or does not believe that plastic, noncompostable shopping bags should be banned.

Item e:

Then

[tex]P(B|A) = \frac{P(A \cap B)}{P(A)} = \frac{0.276}{0.686} = 0.402[/tex]

0.402 = 40.2% probability that the adult does not believe that plastic, noncompostable shopping bags should be banned given that the adult does recycle.

Well, it's a square, a rhombus and a rectangle.

In geometry, a square is a regular quadrilateral, which means that it has four equal sides and four equal angles (90-degree angles, or 100-gradian angles or right angles). It can also be defined as a rectangle in which two adjacent sides have equal length.

A rhombus is a quadrilateral whose four sides all have the same length.

Answer:

2h/ t^2 - 2v/t =g

Step-by-step explanation:

h = vt+1/2 gt^2

Subtract vt from each side

h - vt = vt+1/2 gt^2 -vt

h - vt = 1/2 gt^2

Multiply each side by 2

2( h-vt) = 2 * 1/2 g t^2

2 ( h-vt) = gt^2

Divide each side by t^2

2 ( h-vt) / t^2= gt^2/t^2

2/t^2 (h -vt) = g

Distribute

2h/ t^2 - 2v/t =g
