Answer:

6.02139

Step-by-step explanation:

345° × π/180 = 6.021rad

The number 345 degrees can be written in the form of radians would be 23π/12 radians.

Used the concept of measurement unit which states that,

A measurement unit is a standard quality used to express a physical quantity. Also, it refers to the comparison between the unknown quantity with the known quantity.

Since,

1 degree = π/180 radians

Now, convert 345 degrees to radians as,

1 degree = π/180 radians

345 degree = 345 × π/180 radians

= 23π/12 radians

Therefore, we get;

345 degree = 23π/12 radians

Answer:

The answer is below

Step-by-step explanation:

A fraction is the ratio of the numerator to the denominator. It is given as:

Fraction = numerator / denominator.

If both the numerator and denominator are equal then:

numerator = denominator

Fraction = numerator / denominator = numerator / numerator = 1

When using fractions with units, if you want the units to be canceled out the both the numerator and the denominator must have the same units.

Because the numerator and denominator of the fraction are equivalent, the value of the fraction is 1.  Multiplying by 1 does not change the quantity, but using an equivalence will change the units (or label) o In order for units to cancel they must be in both numerator and denominator of the fraction,

Step-by-step explanation:

1. You already got the first step, where D is the midpoint of AC and AB is congruent to BC, since it's given.

2. AD will be congruent to DC, via the definition of a midpoint (a midpoint is the middle point of a line segment, and it splits the segment into two congruent parts)

3. BD is equal to BD, via reflexive property. ( It's a shared side between the two triangles)

4. that means that ΔADB ≅ΔCDB via SSS rule.

5. ∠ABD ≅∠CDB by CPCTC (corresponding parts of congruent triangles are congruent)

Hope this helps! :)

Answer:

CDB is the longer bottom point so if you want to find the circumference or ≅ you have to find the ratio it would be the points CBD

Answer:

(-1, -2)

Step-by-step explanation:

-2x + y = 0

y = 2x

5x + 3y = -11

5x + 3(2x) = -11 => 5x + 6x = -11

11x = -11

x = -1

-2(-1) + y= 0

2 + y = 0 => y = -2

Answer:

-1/14

Step-by-step explanation:

Use rise over run, (y2 - y1) / (x2 - x1)

Plug in the points:

(y2 - y1) / (x2 - x1)

(2 - 1) / (-17 + 3)

1 / -14

= -1/14

So, the slope is -1/14

Answer:

[tex]55.45+p[/tex]

The decimal point is one step behind and rounded the number.

Step-by-step explanation:

Cost of leggings = $24.95

Cost of crewneck = $30.50

Cost of new purse = p

The correct expression to find the total cost of her shopping is

[tex]24.95+30.5+p[/tex]

[tex]=55.45+p[/tex]

What Paige did was she put the decimal point one step behind and rounded the number.

[tex]2.495+3.05+p[/tex]

[tex]=5.545+p[/tex]

[tex]=5.55+p[/tex]

So, she got the wrong expression.

Answer:

5 miles per hour

Step-by-step explanation:

Let the speed of Kelly is [tex]v_1[/tex] miles per hour and speed of Raul is v₂ miles per hour.

Since, speed = [tex]\frac{\text{Distance}}{\text{Time}}[/tex]

Kelly took 135 minutes to cover 90 miles from New York to Philadelphia.

∵ 1 minute = [tex]\frac{1}{60}[/tex] hours

∴ 135 minutes = [tex]\frac{135}{60}[/tex] = [tex]\frac{9}{4}[/tex] hours

v₁ = [tex]\frac{90}{\frac{9}{4}}[/tex]

   = [tex]90\times \frac{4}{9}[/tex]

   = 40 miles per hour

Raul took 153 minutes to cover the same distance as Kelly,

∵ 1 minute = [tex]\frac{1}{60}[/tex] hours

∴ 153 minutes = [tex]\frac{153}{60}[/tex] = [tex]\frac{51}{20}[/tex] hours

v₂ = [tex]\frac{90}{\frac{51}{20}}[/tex]

    [tex]=90\times \frac{20}{51}[/tex]                        

    = 35.29

    ≈ 35.3 miles per hours

v₁ - v₂ = 40 - 35.3

         = 4.7

         ≈ 5.0 miles per hours

Therefore, Kelly is 5 miles per hours faster than Raul.
