Answer:

99 yd

Step-by-step explanation:

When I add these, I line them up vertically

  29 yd. 2ft. 11 in.

+ 55 yd. 1 ft. 10 in.

+ 13 yd. 1 ft.  3 in.

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

97 yd  4ft   24 in

We know that 12 in = 1 ft

so 24 in = 2ft

Subtract 24 in and add 2 ft

97 yd  4ft   24 in

           +2ft  -24 in

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

97  yd   6ft

We know 3 ft = 1yd

so 6ft = 2yd

Subtract 6ft and add 2 yd

97  yd   6ft

+2yd   - 6ft

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

99 yd

Step-by-step explanation:

|2x + 6| − 4 = 20

Add 4 to each side

|2x + 6| − 4+4 = 20+4

|2x + 6|  = 24

Now we have an absolute value equation that has the absolute value isolated.  We can separate them, have two equations, one positive and one negative.

2x+6 =24   and 2x+6=-24

Subtract 6 from each side

2x+6-6=24 -6    2x+6-6 = -24-6

2x = 18                   2x =-30

Divide by 2

2x/2 = 18/2          2x/2 = -30/2

x =9                        x=-15

Answer: D) 4/5

================================================

Explanation:

There are a few ways to see how this is the answer.

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

The first is to notice how 16/20 = 0.80 when using long division or a calculator. At the same time, 4/5 = 0.80 as well. So that means 16/20 = 4/5.

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

Another way to see how this works is to multiply top and bottom of 4/5 by 4. So we have 4*4 = 16 as the new numerator and 5*4 = 20 as the new denominator. Going in reverse, you can divide each piece of 16/20 by the GCF 4 to reduce this fraction into 4/5.

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

Finally, we can equate the two fractions and cross multiply

16/20 = 4/5

16*5 = 20*4

80 = 80

Both sides are the same value, so that confirms the original equation is true as well.

Answer:

Step-by-step explanation:

In mathematics, the complex conjugate of a complex number is the number with an equal real part and an imaginary part equal in magnitude but opposite in sign. For example, the complex conjugate of 3 + 4i is 3 − 4i. In polar form, the conjugate of is.

A complex conjugate is the element of a complex number that has the same real part but an opposite-sign imaginary part, and multiplying a complex number by its conjugate yields a real number.

A complex conjugate in mathematics is a paired element of a complex number that has the same real part but an opposite-sign imaginary part. When you have a complex number, let's call it A, which can be expressed in the form (a + ib) where 'a' is the real part and 'b' is the imaginary part, the complex conjugate of A, denoted as A*, would be (a - ib). One important property of complex conjugates is that when you multiply a complex number by its conjugate, you get a real number. This is because the product A* A = (a + ib) (a - ib) = a² + b².

For example, if a complex number is a = 3 + 4i, its complex conjugate would be a* = 3 - 4i. Multiplying a by its conjugate, we get a* a = (3 + 4i) (3 - 4i) = 9 + 16 = 25, which is a real number. This property is very useful, especially in fields such as quantum mechanics, where physical measurements must yield real numbers.

You will have the points: (0,0) and (1,10) and (2,20) and (3,30) etc etc

Plot at least 2 of these points. Then draw a line through them.

Each point has an x,y pair such that the y value is ten times the x value

For example, if x = 2, then

y = 10*x = 10*2 = 20

so that shows how (2,20) is one of the points.

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

The domain would be the set of positive whole numbers assuming Tyler can only work a whole number of hours. If partial time values are accepted, then the domain would be the set of positive real numbers. Negative x values are not allowed as Tyler can't work negative 3 hours for instance.

In a similar fashion, the range is the set {0, 10, 20, 30, 40, ...} incrementing by multiples of 10 if x is the set of positive whole numbers. If x is the set of positive real numbers, then y can be 0 or larger which sets up the range of y being the set of positive real numbers as well.

The x-intercept of the equation y = -2.65x + 25 is approximately 9.43. The x-intercept generally represents the value of x at which y is zero or the point where correlation between x and y starts.

The x-intercept of a graph is the point at which the line crosses the x-axis. In terms of your equation y = -2.65x + 25, the x-intercept is found when y equals 0. By setting y equal to 0 and solving for x, we get: 0 = -2.65x + 25. Isolate x by dividing both sides by -2.65 and adding 25. This calculates to x ≈ 9.43. In terms of real life situations, the x-intercept often represents the value of x where y is nil or where the correlation between x and y begins. However, the real-world interpretation of this value depends on the context of the problem.

Rounding to the whole number or an estimation.

Step-by-step explanation: Pretty sure there isn't really a name for this

Rounding a number to its first digit is known as rounding to the nearest whole number. This method simplifies calculations while maintaining a number's approximate value.

The process of rounding a number to its first digit is often referred to as rounding to the nearest whole number. For example, if you have a number like 4.58, rounded to the nearest whole number it's 5, because the number next to 4 is 5 which is equal or higher than 5. But if the number was 4.42, rounded to the nearest whole number it's 4, because the number next to 4 is 2 which is less than 5. This rounding method applies when you want to make calculations simpler, while still keeping the number's value close to what it was.

The answer is:

The probability that both John and Ted will be on time is 48%.

Since we are dealing with percentages, in order to make it easy to understand, let's remember that percentages are used to simplify the way we refer to something, talking in numeric terms. For example, meaning 100% it's equal to say that somethinh is complete, or absolute. Also, we can see the percentage as a ratio that is expressed as a fraction of the number 100 or [tex]\frac{1}{100}[/tex]

From the statement the know that John is late 20% of the time, making it easy to understand, it's equal to say that from 100 times, John is late 20 times.

So, calculating we have:

For John:

[tex]Probability=TotalTimes(percent)-LateTimes(Percent)\\\\Probability=100-20=80[/tex]

So, we have that the probability that John will be on time is 80%.

For Ted:

[tex]Probability=TotalTimes(percent)-LateTimes(Percent)\\\\Probability=100-40=60[/tex]

So, we have that the probability that Ted will be on time is 60%.

Now, to calculate the probability that both John and Ted will be on time, we need to calculate the combined probability. It can be calculated using the following equation:

[tex]CombinedProbability=Probability_{1}*Probability_{2}[/tex]

Let be:

[tex]Probability_{1}=80(percent)=\frac{80}{100}=0.8\\\\Probability_{2}=60(percent)=\frac{60}{100}=0.6[/tex]

So, substituting and calculating we have:

[tex]CombinedProbability=Probability_{1}*Probability_{2}[/tex]

[tex]CombinedProbability=0.8*0.6=0.48=48(percent)[/tex]

Hence, we have that the probability that both John and Ted will be on time is 48%.

Answer: The pilot traveling 400 mph rising at an angle 30 degrees is going to gain more altitude faster

======================================================

Explanation:

Draw out the triangles as you see in the attached image below. We'll use the sine rule because we want to tie together the unknown height (h) which is the opposite side of the reference angle, to the known hypotenuse (the speed of the aircraft)

For the first plane,

sin(angle) = opposite/hypotenuse

sin(30) = h/400

h = 400*sin(30)

h = 200

so the first plane is gaining altitude at 200 mph (each hour, the plane is 200 miles higher up)

For the second plane

sin(angle) = opposite/hypotenuse

sin(40) = h/300

h = 300*sin(40)

h = 192.836282905961

h = 192.84

which is smaller than the previous result (200)

So we see that the first plane is rising faster

Answer:

a pilot traveling 400 mph and rising at an angle of 30 degrees

Final answer:

Kendra's original allowance was $10.

Explanation:

To find out how much Kendra's allowance was, we can use algebraic equations. Let 'x' represent Kendra's original allowance.

Kendra lost half of her allowance, which means she had x/2 left.

Then her mother gave her four more dollars, so now she has x/2 + 4.

Given that Kendra has $9, we can set up the equation x/2 + 4 = 9 and solve for x.

x/2 + 4 = 9

x/2 = 9 - 4

x/2 = 5

Multiplying both sides of the equation by 2, we get x = 10.

Therefore, Kendra's allowance was $10.
