Answer: 50 degrees.

Step-by-step explanation:

The sum of the interior angles of a triangle is 180 degrees. Then, you can find the missing angle "x" of the larger triangle (Observe the figure attached):

[tex]53\°+45\°+x=180\°\\x=180\°-53\°-45\°\\x=82\°[/tex]

We know that:

[tex]x+y+68\°=180\°[/tex]

Then, "y" you need to substitute values and solve for "y":

[tex]y=180\°-68\°-82\°=30\°[/tex]

Then the angle ? is:

[tex]?=180\°-30\°-100\°\\?=50\°[/tex]

ANSWER

?=50°

EXPLANATION

From the diagram,

x+45+53=180

x+98=180

x=180-98

x=82°

Using angles on a straight line property,

x+68+y=180

82+68+y=180

150+y=180

y=180-150

y=30°

Using the sum of interior angles of the triangle,

?+y+100=180

?+30+100=180

?+130=180

?=180-130

?=50°

The question involves mathematical sampling techniques to generate categorical data from a high school population, which is shown in a pie chart and involves creating a stratified sample by selecting students from each year.

The question pertains to a mathematical concept used in the selection of a sample from a population, which in this scenario, is a group of high school students. This involves using a random number generator to select two class years (freshman, sophomore, junior, or senior) and then including all students from those two years in the sample. The sampling process will result in categorical data, which can be represented in a pie chart as shown in Solution 1.10.

Moreover, organizing the students' names by classification and selecting 25 students from each (a, d) ensures a stratified sample of high school students across different academic stages.

In the context of the presented educational tasks, students might explore how their learning experiences have intersected with personal and global changes, engaging in an analysis of polymorphism, continuous variation, and clinal distribution based on surveyed traits among their peers (Conclusion).

Answer:

Step-by-step explanation:

The easiest way for me to answer your question is just to do it. If we agree, all well and good. If we don't, then you have the way I did it.

A = (4.75*x + 125)/10000

A = (4.75*10000 + 125) / 10000

A = (47500 + 125) / 10000

A = 47625/10000

A = 4.76

So it looks like we both think it is A.

The question is deceptive because the 125 is really quite small compared to 47500.

Answer:

A. $4.76

Step-by-step explanation:

This case is fairly typical of average cost problems. There is some fixed cost that is amortized over the number of T-shirts produced, and there is some variable cost associated with each item.

Here, if you divide out the equation, you get ...

A = 4.75 + 125/x

Then for x=10,000, the value of A is ...

A = 4.75 +125/10,000 = 4.75 +0.0125 ≈ 4.76

_____

Once you see that the fixed cost of $125 is divided by 10,000, you can look for an answer choice that is very slightly higher than $4.75.

Answer:

~24.4%

Step-by-step explanation:

A circle is 360 degrees, we all know this.

The angle representing Techno is 28° While Country has a 60°. Combine this and we get 88° of people total chose country or techno. 88° divided by 360° gives us 0.2444444... With percentages, we move the decimal two places to the right, giving us:

~24.4%

Answer:

  0.5 cm

Step-by-step explanation:

You are given angles B and C and side b, so you can put those values into the given equation:

  sin(105°)/(2 cm) = sin(15°)/c

Multiply this equation by c·(2 cm)/sin(105°) and you get ...

  c = (2 cm)·sin(15°)/sin(105°) ≈ 0.535898 cm

  c ≈ 0.5 cm

_____

Comment on the given equation

When using the Law of Sines to find side lengths, I prefer to write the proportion in a form with the side length of interest in the numerator:

  b/sin(B) = c/sin(C)

or

  c/b = sin(C)/sin(B)

Using either of these forms, it is one step to find the value of c: Multiply the equation by the inverse of the coefficient of c.

  c = b·sin(C)/sin(B)

Answer:

1/4 ft

Step-by-step explanation:

The area is given by the product of length and width. Since the width of the rectangle was not changed, the new length L satisfies the equation ...

(1/6 ft)·L = 11/72 ft²

Multiplying by 6/ft tells us the new length:

L = (6/ft)·11/72 ft² = 11/12 ft

The original length is 2/3 ft shorter so is ...

L -2/3 ft = 11/12 ft -8/12 ft = 3/12 ft

L = 1/4 ft

Answer:

C) 5000(0.987783)^t

Step-by-step explanation:

The monthly interest rate is the APR divided by 12, so is 22%/12 ≈ 0.018333.

Each month, the previous balance (B) has interest charges added to it, so the new balance is ...

balance with interest charges = B + (22%)/12×B = 1.018333×B

The minimum payment is 3% of this amount, so the new balance for the next month is ...

balance after payment = (1.018333B)(1 - 0.03) = 0.987783B

Since the balance is multiplied by 0.987783 each month, after t payments, the balance starting with 5000 will be ...

5000×0.987783^t . . . . . . . . . matches choice C

Answer:

  $311.74

Step-by-step explanation:

A financial calculator computes the payment amount to be $311.74.

___

Your graphing calculator may have the capability to do this. Certainly, such calculators are available in spreadsheet programs and on the web.

___

The appropriate formula is the one for the sum of terms of a geometric series.

  Sn = a1·((1+r)^n -1)/(r) . . . . . where r is the monthly interest rate (0.005) and n is the number of payments (480). Filling in the given numbers, you have ...

  $620827.46 = a1·(1.005^480 -1)/.005 = 1991.4907·a1

Then ...

  $620827.46/1991.4907 = a1 ≈ $311.74

To achieve a retirement income of $4000 per month with a 6% APR compounded monthly, a nest egg of $620,827.46, and a retirement plan spanning 40 years, one should deposit about $288.69 into the account each month.

This question pertains to the concept of future value and annuities in finance. The purpose is to determine the monthly deposits required to achieve a specified future value, which in this case is the desired retirement income. Here, we use the future value of a series formula: FV = P * [((1 + r)^nt - 1) / r], where P is the monthly payment, r is the monthly interest rate, n is the number of times interest is compounded per year, and t is the time in years. Given that the future value FV is $620,827.46, the interest rate r is 0.06/12 (since it's compounded monthly), n is 12 (compounded twelve times a year), and t is 40 years. The aim is to solve for P, the monthly payment: P = FV / [((1 + r)^nt - 1) / r]. Plugging in the given values, the result is approximately $288.69. Thus, to receive a retirement income of $4000 per month, you should deposit about $288.69 into the account each month.

It is the factored form of a 2nd-degree polynomial, so is a quadratic function.

Answer:

5.13 feet

Step-by-step explanation:

So, we have the full dimensions of flag #1, and we have the partial dimensions of flag #2, which should follow the same ratio as flag #1, since not indicated otherwise.

When you need to compare dimensions like that, the easiest way to proceed is to do a cross-multiplication. Let's say x is the length of flag #2 we're looking for.  It's ratio over the width of flag #2 will be the same as the ratio of the length of flag #1 over its width, so:

[tex]\frac{x}{2.7} = \frac{1.9}{1}[/tex]

If we isolate x, we have x = (2.7 * 1.9) / 1 = 5.13 feet

Which makes sense since we know the result should be a bit less than 2.7 times 2.

Answer:

$95.48 was his commission

Step-by-step explanation:

First we need to find what the retail cost of the chest is.  If it's marked up 150%, we use 763.84 + 1.5(763.84) which gives us a retail price of $1909.60.  If Ben makes 5% on the sale as his commission, then we take 5% of 1909.60 which, in algebraic terms, looks like this:  .05(1909.60) which is $95.48

3x+2+x+8=180; 4x+10=180; 4x=170; x= 170/4= 42.5

Angle on top is x+8=42.5+8=50.8

Angle on the bottom is 3x+2=3•42.5+2= 129.5

The value of x is 42.5.

The fundamental characteristics listed below make it simple to recognise parallel lines.

Straight lines that are always the same distance apart from one another are called parallel lines.

No matter how far apart they are in any direction, parallel lines will never intersect.

Given:

From figure (x+8) and(3x+ 2) are angles on same side of transversal.

So, (x+ 8) + (3x+ 2)= 180

4x+ 10 = 180

4x = 180- 10

4x= 170

x= 170/4

x= 42.5

Hence, the value of x is 42.5.

Step-by-step explanation:

The line to the left of x=3 goes up from 4 to 12 as x goes from 0 to 3. Thus, the slope of it is ...

slope = (12 -4)/(3 -0) = 8/3

It intersects the y-axis at y=4, so its equation is ...

y = (8/3)x +4

__

For x > 3, we observe that the curve falls 3 units (from 12 to 9) as x goes from 3 to 4, then falls 9 units (from 9 to 0) as x goes from 4 to 5. The slope of the curved portion at x=3 looks like it might be zero, suggesting a polynomial function instead of an exponential function.

We note that the change in the value of y=x^2 as x goes from 0 to 1 is 1, then as x goes from 1 to 2, it is 4-1 = 3 — 3 times the change in the first interval. This suggests a quadratic function that has been scaled by a vertical factor of -3, and had its vertex moved to (3, 12). Such a function is described by ...

y = -3(x -3)² +12

Then the graph is modeled by a piecewise function, defined as a line for x < 3, and as a quadratic curve for x > 3. Since the function is continuous at x=3, we can put "or equal to" signs on either or both of these boundaries. We choose to write it as ...

f(x) = (8/3)x +4, x ≤ 3; -3(x -3)² +12, x > 3.

It’s A the region one

Answer:

A). when the region is divided into a greater number of rectangles.

Step-by-step explanation:

This forms the basics of integration.

Integration can be use to calculate areas under the curve. To find the area under the curve we try to approximate the area under the curve by using rectangles. When we increased the number of rectangles of equal width of the rectangles, a better approximation of the area is obtained. We then find the area of each infinitesimally small rectangle and then integrate by taking two limits, the upper limit and the lower limit.

Answer:

  a) center: (-3, 2)

  b) radius: √65

  c) equation: (x +3)² +(y -2)² = 65

Step-by-step explanation:

a) The center (point A) is the midpoint of the diameter, so its coordinates are the average of the endpoint coordinates:

  A = (P +Q)/2 = ((-10, -2) +(4, 6))/2

  = (-10+4, -2+6)/2 = (-6, 4)/2

  A = (-3, 2)

__

b) The radius is the distance from the center to one end of the diameter. The distance formula can be used to find that.

  r = √((x2 -x1)² +(y2 -y1)²) = √((4-(-3))² +(6 -2)²) = √(49+16)

  r = √65

__

c) The circle centered at (h, k) with radius r has formula ...

  (x -h)² +(y -k)² = r²

So the formula for this circle is ...

  (x +3)² +(y -2)² = 65

Step-by-step explanation:

We have to complete

sin⁡(α+β)/sin⁡(α-β) = ?

The identities that will be used:

sin⁡(α+β)=sin⁡ α cos ⁡β+cos ⁡α sin ⁡β

and

sin⁡(α-β)=sin⁡ α cos⁡ β-cos⁡ α sin⁡ β  

Now:

=   sin⁡(α+β)/sin⁡(α-β)  

=(sin⁡ α cos⁡ β+cos ⁡α sin⁡ β)/(sin ⁡α cos ⁡β-cos ⁡α sin ⁡β)

In order to bring the equation in compact form we wil divide both numerator and denominator with  cos⁡ α cos⁡ β  

=  (((sin ⁡α cos ⁡β+cos ⁡α sin ⁡β))/(cos ⁡α cos ⁡β ))/(((sin α  cos ⁡β-cos ⁡α sin ⁡β))/(cos ⁡α  cos ⁡β))

=((sin⁡ α cos⁡β)/(cos ⁡α cos ⁡β )+(cos ⁡α sin ⁡β)/(cos ⁡α cos ⁡β ))/((sin ⁡α cos ⁡β)/(cos ⁡α  cos ⁡β )-(cos ⁡α sin ⁡β)/(cos ⁡α cos ⁡β))  

=(sin⁡ α/cos ⁡α + sin ⁡β/cos ⁡β )/(sin ⁡α/cos ⁡β - sin ⁡β/cos ⁡β)

=(tan ⁡α+tan ⁡β)/(tan ⁡α-tan ⁡β )

The weight of the water in the pool to the nearest pound is 280,800 pounds.

To find the weight of the water in the swimming pool, we need to calculate the volume of the pool in cubic feet and then use the density of water to determine the weight.

Convert dimensions to consistent units:

The depth of the pool is given in feet (2 feet), so we need to convert the length and width from yards to feet.

1 yard = 3 feet

Length = 25 yards × 3 feet/yard = 75 feet

Width = 10 yards × 3 feet/yard = 30 feet

Calculate the volume of the pool:

Volume = length × width × depth

Volume = 75 feet × 30 feet × 2 feet = 4,500 cubic feet

Calculate the weight of the water:

Weight of water = volume × density

Density of water = 62.4 pounds per cubic foot

Weight = 4,500 cubic feet × 62.4 pounds/cubic foot = 280,800 pounds
