Answer:

25π/6 yd

Step-by-step explanation:

∠DCE = 110°, so arc DFE = 360° − 110° = 250°.

In radians, that's 250° × π/180° = 25π/18.

Arc length is:

s = rθ

s = (3 yd) (25π/18)

s = 25π/6 yd

Answer:

Your answer is B

Step-by-step explanation:

Because if they are already $60 and she wants one more it would be $75

The cost for the 6th pajama bought by Keli is given as $85.

A straight line can be written in the form of equation as, y = mx + c.

Two straight lines intersect each other only at one point.

When two straight lines are parallel to each other the angle between them is zero.

The equation of the straight line from the given graph can be formed as below,

Take any two coordinates from the graph as (1, 10) and (2, 25) respectively.

Suppose the cost be y and the number of pajamas be x.

Now, the equation for the slope can be written as,

(y - 10)/(x - 1) = (25 - 10)/(2 - 1)

⇒ (y - 10)/(x - 1) = 15

⇒ y = 15x - 5.

Then, the cost of 6th pajama can be calculated by substituting x = 6 in the above equation as,

y = 15 × 6 - 5

  = 85

Hence, the cost of sixth pair of pajama is $85.

Answer: 360.73

Step-by-step explanation:

When you come across any question that says [a of b] is just saying a × b.

5.5% of x=5.5% × x

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

Given

5.5% of x=19.84

Converted into numerical expression

5.5% × x=19.84

Divide both sides by 5.5% (0.055)

x=19.84 ÷ 5.5%

simplify

x=360.73 (rounded)

Answer:

360.7273

Step-by-step explanation:

5.5% of 'x' is 19.84

so, x*5.5/100 = 19.84

or, x*5.5 = 1984

or, x = 1984/5.5

so, x=360.7273(answer)

Answer:

x = -6

Step-by-step explanation:

Order of Operations: BPEMDAS

Step 1: Write out equation

2(x - 7) = 5x + 4

Step 2: Distribute parenthesis

2x - 14 = 5x + 4

Step 3: Subtract 2x on both sides

-14 = 3x + 4

Step 4: Subtract 4 on both sides

-18 = 3x

Step 5: Divide both sides by 3

-6 = x

Step 6: Rewrite

x = -6

Answer:

x=-6

Step-by-step explanation:

2(x-7)= 5x+4

2x - 14 = 5x+4

-2x         -2x

-14 = 3x +4

- 4           -4

-18= 3x

18/3 = 3x/3

Answer:

since second company salary, $93,600, is more than first company yearly salary of $65000

Second company pays more

Step-by-step explanation:

To check what job pays more we have to compare yearly salary of both the company offer.

_________________________________________________

Yearly salary from one company = 65k = 65000

Weekly salary from another company = $1800

there are 52 weeks in a year

to get yearly salary , we need to multiply weekly salary with 52.

Yearly salary from another company = Weekly salary*no of wees in a year

Yearly salary from another company = 52*$1800 = $93,600

since second company salary, $93,600, is more than first company yearly salary of $65000

Second company pays more

Answer:

B, 13 cubic yards.

Step-by-step explanation:

You didn't give a graph, but I'm assuming you had the same question as me (I attached the graph that I had). I took the test and got the right answer.

The recommended amount of mulch for a flowerbed with a radius of 20 feet is 13 cubic yards

The vertex of the graph is given as:

Vertex = (0,0.5)

The equation of the graph is given as:

[tex]y = 0.5 * 1.177^x[/tex]

When the radius is 20 feet, we have:

y = 0.5 * 1.177²⁰

Evaluate

y = 13.02

Approximate

y = 13.0

Hence, the recommended amount of mulch for a flowerbed with a radius of 20 feet is 13 cubic yards

Answer:

t= -15/2       or       t= -7.5

Step-by-step explanation:

We are given the equation:

[tex]\frac{-6}{5}t=9[/tex]

and asked to solve for t. Therefore, we must isolate t on one side of the equation.

t is being multiplied by -6/5. The inverse of multiplication is division. We should divided both sides by -6/5, but we are dividing by a fraction. Instead, we can multiply by the reciprocal.

To find the reciprocal, flip the numerator (top number)  and denominator (bottom number).

-6/5 ----> -5/6

Multiply both sides of the equation by -5/6

[tex]\frac{-5}{6} *\frac{-6}{5}t=9 *\frac{-5}{6}[/tex]

[tex]t=9 *\frac{-5}{6}[/tex]

[tex]t=\frac{9}1 *\frac{-5}{6}[/tex]

Multiply across the numerator and denominator.

[tex]t= \frac{9*-5}{1*6}[/tex]

[tex]t=\frac{-45}{6}[/tex]

Simplify the fraction. Both the numerator and denominator can be divided by 3.

[tex]t=\frac{-45/3}{6/3}[/tex]

[tex]t=\frac{-15}{2}[/tex]

[tex]t= -7.5[/tex]

t is equal to -15/2 or -7.5

Complementary angles are angles whose sum is 90 degrees.

This means that we can make an equation.

[tex](8x-23)+(7x-7)=90[/tex]

[tex]15x-30=90[/tex]

[tex]15x=120[/tex]

[tex]x=8[/tex]

Then we can plug in the value we got into the express for angle A's measure.

[tex]8(5)-23[/tex]

[tex]40-23[/tex]

[tex]17[/tex]

The measure of angle A is 17 degrees.

Answer:

The line that can be drawn through points D and E is contained in plane Y.

Step-by-step explanation:

Let's just go through all of these answer choices.

The first one says that "The line that can be drawn through points C and D is contained in plane Y." Is this true? If we drew a line connecting points C and D, it looks like it would cross through both planes X and Y, so it cannot be contained in only plane Y. This is false.

The second one says that "The line that can be drawn through points D and E is contained in plane Y." If we imagine a straight line going from point D to point E, it looks like it's just a line in plane Y; so this can be contained in plane Y. This seems true.

The third one says that "The only point that can lie in plane X is point F." This is false because plane X has a ton of points, but point F is just the only one that's labeled. This is false

The fourth one is similar, and says that "The only points that can lie in plane Y are points D and E." Again, this is false because points D and E just happen to be the only two labeled points, but there are infinitely many points on plane Y; points D and E are not all of them.

The second answer choice is true.

Answer:

40

Step-by-step explanation:

Given that:

Number of options available for transmission = 2 (Standard or Automatic)

Number of options for doors = 2 (2 doors or 4 doors)

Number of exterior colors available = 10

To find:

Total number of outcomes = ?

Solution:

First of all, let us calculate the number of outcomes for the transmission mode and number of doors options.

1. Standard - 2 doors

2. Standard - 4 doors

3. Automatic - 2 doors

4. Automatic - 4 doors

Number of outcomes possible = 4 (which is equal to number of transmission mode available multiplied by number of doors options i.e. 2[tex]\times 2[/tex])

Now, these 4 will be mapped with 10 different exterior colors.

Therefore total number of outcomes possible :

Number of transmission modes [tex]\times[/tex] Number of doors options  [tex]\times[/tex] Number of exterior colors

2 [tex]\times[/tex] 2 [tex]\times[/tex] 10 = 40

The number of possible outcomes of a new car will be 40. Then the correct option is B.

A sample is a collection of well-defined elements. A sample is represented by a capital letter symbol and the number of elements in the finite sample is shown as a curly bracket {..}.

A new car is available with standard or automatic transmission, two or four doors, and it is available in 10 exterior colors.

Then the number of possible outcomes will be

Answer:

20 rabbits, 10 chickens

Step-by-step explanation:

Because chickens and rabbits each have 2 eyes, the number of animals is 60 ÷ 2 = 30.

Let's say that all of the 30 animals are chickens. There would be a total of 30 × 2 = 60 legs.

So the extra (100 – 60) = 40 legs must have come from the rabbits.

Every rabbit has (4 – 2) = 2 more legs than a chicken.

So there are 40 ÷ 2 = 20 rabbits and 30 – 20 = 10 chickens.

The question lacks the required diagram. Find the diagram attached.

From the diagram the length of the vector along x component is given as:

Vx = Vcos(theta)

theta is the angle between the vector and the x axis

V is the length of the vector

Given

theta = 22°

V = 15

Substitute the given values into the formula above

Vx = 15cos22°

Vx = 15×0.9272

Vx = 13.91
