Answer:

m<ALO=35°

Step-by-step explanation:

we know that

The right triangle AOL is congruent with the right triangle BOL

because

OA=OB=radius of the circle

OL is a common side

LA=LB ---> by applying the Pythagoras theorem

therefore

m<AOL=m<AOB/2

m<AOL=110°/2

m<AOL=55°

Remember that

m<AOL+m<ALO=90° ------> by complementary angles

m<ALO=90°-55°=35°

So think of it like this she starts off $32 negative and subtract 3 from each box of cards she makes . So each box of cards she will make $8 that being said

32/8 =4 (it will take 4 box of cards to pay off her booth expense).

Sales would be 11x 4 =44

Expenditures would be 3x4 =32 (the amount used to make cards ) +32(the amount paid for the booth)

Which in total would be $64

Sidney needs to sell [tex]\( \boxed{4} \)[/tex] boxes of cards to cover her expenditures, totaling [tex]\( \$44 \)[/tex] in sales and expenditures.

To determine when Sidney's sales will cover her expenditures, we set up the following equations:

1. Cost equation:

  Total cost C consists of booth cost [tex]\( \$32 \)[/tex] plus material cost [tex]\( \$3 \)[/tex] per box:

  [tex]\[ C = 32 + 3n \][/tex]

  where n is the number of boxes of cards sold.

2. Revenue equation:

  Total revenue [tex]\( R \)[/tex] is obtained from selling each box for [tex]\( \$11 \)[/tex] :

  [tex]\[ R = 11n \][/tex]

3. Break-even point:

  To find when sales cover expenditures, set [tex]\( R = C \)[/tex]:

  [tex]\[ 11n = 32 + 3n \][/tex]

  Simplify and solve for n :

  [tex]\[ 11n - 3n = 32 \][/tex]

  [tex]\[ 8n = 32 \][/tex]

  [tex]\[ n = \frac{32}{8} = 4 \][/tex]

4. Calculation:

  - Number of cards: Sidney needs to sell 4 boxes of cards.

  - Sales: Total revenue [tex]\( R \)[/tex] at break-even point:

    [tex]\[ R = 11 \cdot 4 = \$44 \][/tex]

  - Expenditures: Total cost C at break-even point:

    [tex]\[ C = 32 + 3 \cdot 4 = \$44 \][/tex]

Sidney will cover her expenditures after selling 4 boxes of cards, where her total revenue from sales equals her total costs, including booth fees and material costs. This ensures she breaks even in terms of financial outlay versus income from sales.

Sidney needs to sell 4 boxes of cards to cover her expenditures, resulting in total sales of [tex]\( \$44 \)[/tex] and total expenditures of [tex]\( \$44 \)[/tex].

The expressions that are equivalent to 2(2x + 1) are A. 4x + 2 and B. 2(1 + 2x).

The expression 2(2x + 1) can be simplified by distributing the 2 to both terms in the parentheses. This gives us 2 * 2x + 2 * 1, which simplifies to 4x + 2. Therefore, option A (4x + 2) is equivalent to 2(2x + 1).

We can also distribute the 2 to the terms inside the parentheses in option B (2(1 + 2x)). This gives us 2 * 1 + 2 * 2x, which simplifies to 2 + 4x, also equivalent to 2(2x + 1).

Option C (2(2x) + 1) is not equivalent because it simplifies to 4x + 1, not 2(2x + 1).

Option D (2x + 1 + 2x + 1) is not equivalent because it simplifies to 4x + 2, not 2(2x + 1).

Option E (x + x + x + x + 1 + 1) is not equivalent because it simplifies to 4x + 2, not 2(2x + 1).

The correct answer is:

y = -4x + 3

Answer:

The equation "y = -4 x + 3" represents a line parallel to the line shown on the graph.

Step-by-step explanation:

The line shown on the graph corresponds to the equation "y = -4 x + 8".

All linear functions with the same slope are represented by parallel lines.

The slope of the function of the graph is -4 and the slope function of the answer is -4, too. Therefore both of them represents parallel lines.

The function "y = 4 x - 1" has got different slope, so it represents a different line.

m∠KPF = 29°, m∠H = 129°. Using angle properties, we found m∠KPF by subtracting known angles from 360° and m∠H by alternate interior angles.

To solve this problem, we'll use several properties of angles in circles, particularly those formed by chords, secants, and tangents intersecting inside or outside a circle.

Given:

- PKHE is an inscribed quadrilateral.

- ∠E = 120°.

- ∠EPK = 51°.

- PF is parallel to EH.

We need to find:

- m∠KPF

- m∠H

Let's start by drawing the situation:

        P

       / \

      /   \

     /     \

    /_______\

   E         H

      K

Step 1: Determine m∠KPE

Since PF is parallel to EH, we have alternate interior angles:

m∠KPE = m∠EPK = 51°

Step 2: Find m∠KEH

Inscribed angle ∠KEH is half the measure of its intercepted arc, ∠E. So:

m∠KEH = 1/2× m∠E = 1/2× 120° = 60°

Step 3: Find m∠KPH

∠KPH is an exterior angle to triangle KPE:

m∠KPH = m∠KPE + m∠KEH

        = 51° + 60°

        = 111°

Step 4: Find m∠KPF

In quadrilateral KPFH, the sum of angles is 360°. So:

m∠KPF + m∠KPH + m∠E + m∠H = 360°

m∠KPF + 111° + 120° + m∠H = 360°

m∠KPF + m∠H = 360° - 111° - 120°

m∠KPF + m∠H = 129°

We'll use this relationship in the next step.

Step 5: Find m∠H

Using the fact that PF is parallel to EH, we have alternate interior angles:

m∠H = m∠KPF = 129°

Step 6: Find m∠KPF

From step 4:

m∠KPF + m∠H = 129°

m∠KPF + 129° = 129°

m∠KPF = 0°

So, the final answers are:

- m∠KPF = 0°

- m∠H = 129°

Answer:

∠QRS = 114°

Step-by-step explanation:

Note that the external angle ∠QRS is equal to the sum of the 2 opposite interior angles, hence

∠QRS = ∠PQR + ∠QPR = 52° + 62° = 114°

The measure of angle QRS in a triangle depends on the properties of the triangle and measurements of other angles. Without additional information, it's impossible to provide a definitive measure for angle QRS. A triangle's total angles are always 180 degrees.

In order to answer your question about the measure of ∠QRS, we first need information about the other angles in the triangle or the property that defines this triangle. For instance, if we know that this is a right-angle triangle and we have the measure of one of the other angles, we can easily find ∠QRS as a triangle's total angles are always 180 degrees. Alternatively, if this is an equilateral triangle, then all angles measure 60 degrees. Without more specific information, it is impossible to definitively state the measure of ∠QRS.

Final answer:

The value that is two standard deviations above the mean for the depth of snow at Yellowstone's lower geyser basin is calculated to be 4.94 inches.

Explanation:

To find the value that is two standard deviations above the mean in a normally distributed set of data, you simply add two times the standard deviation to the mean. Given that the mean depth of snow at Yellowstone's lower geyser basin is 3.9 inches with a standard deviation of 0.52 inches, we perform the following calculation:

Value = Mean + (2 × Standard Deviation)

Value = 3.9 + (2 × 0.52)

Value = 3.9 + 1.04

Value = 4.94 inches

Therefore, two standard deviations above the mean is 4.94 inches of snow.

The value that is two standard deviations above the mean depth of the snow at Yellowstone National Park in April at the lower geyser basin is 4.94 inches.

The value that is two standard deviations above the mean is calculated as follows:

- Mean= 3.9 inches

- Standard deviation = 0.52 inches

To find the value that is two standard deviations above the mean, we multiply the standard deviation by 2 and then add this to the mean:

- Value = Mean + (2 × Standard deviation)

- Value = 3.9 + (2 × 0.52)

- Value = 3.9 + 1.04

- Value = 4.94 inches

Answer:

Step-by-step explanation:

If W is the midpoint of VX then VW = WX. Therefore we have the equation:

2x + 5 = 4x - 3          subtract 5 from both sides

2x = 4x - 8       subtract 4x from both sides

-2x = -8        divide both sides by (-2)

x = 4

VX = VW + WX

VX = 2x + 5 + 4x - 3 = (2x + 4x) + (5 - 3) = 6x + 2

Put the value of x = 4 to 6x + 2:

VX = 6(4) + 2 = 24 + 2 = 26

The length of line segment VX, given W is the midpoint and the lengths of VW and WX are represented by 2x+5 and 4x-3 respectively, is 26 units.

In the given problem, W is the midpoint of VX. This indicates that VW is equal to WX. So, we can set up an equation using the given expressions for VW (2x+5) and WX (4x-3).

We have:
2x+5 = 4x-3

By rearranging the terms, we can find the value of x:
2x-4x = -3-5
-2x=-8
x = 4

Substitute x=4 in either VW or WX to find the length of half of VX: 2x+5 = 2*4+5 = 13.

Since W is the midpoint, VW = WX, so VX = VW + WX = 13 + 13 = 26.

Find the dimensions of the floor of the doll house.

Apply the formula:

[tex]A=lw[/tex]

Where  A is the area, l is the lenght and w is the width.

You know that:

[tex]A=864\\w=\frac{2}{3}l[/tex]

Then you can solve for l:

[tex]864=l(\frac{2}{3}l)\\\\864=\frac{2}{3}l^2\\\\l=\sqrt{\frac{864*3}{2}}\\\\l=36in[/tex]

Then the width is:

[tex]w=\frac{2}{3}(36)=24in[/tex]

Therefore, the dimensions of the floor on the blueprint of the doll house are:

[tex]l'=\frac{1}{4}(36in)=9in\\\\w'=\frac{1}{4}(24in)=6in[/tex]

Answer:

Step-by-step explanation:

The actual dollhouse floor measurements were figured out to be 24 by 36.

24x36 = 864 square inches for the area, which matches to the problem.

The blueprint measurements are to be 1/4 of the actual measurements, so 1/4 of 24 is 6, and 1/4 of 36 is 9.  Therefore, the scaled down measurements of the dollhouse floor are 6x9, which supposedly solves the problem.

But my family and I wondering -- if the actual floor area is 864, and the scaled down drawing is supposed to be 1/4 the size of the actual, then shouldn't the scaled down blueprint area be 1/4 of 864, so 216??

And 6x9 equals 54, not 216!  

What are we missing??
