Answer:

  12 11/24 radians (combined angular motion)

Step-by-step explanation:

In one hour, the combined angular motion is ...

  (2π)(1 +1/12) = 13π/6 radians

Then in the 5 3/4 hours between 1 pm and 6:45 pm, the angular motion of the two hands will total ...

  (23/4)(13π/6) radians = 299π/24 radians = 12 11/24 radians

given l is parallel to m, find the measure of angle ptu

Answers

Answer:

Angle ptu = 116°

as line L is parallel to m

angle pqt = 89° ( vertically opposite angle)

angle tpq = 3x° ( vertically opposite angles).

in triangle pqt

angle p + angle q + angle t = 180° (angle sum proper of a triangle)

Let the unknown angle ptq be X

3x + 89 + X = 180°

3x + x + 89 = 180

4x + 89 = 180

4x = 180 - 89

4x = 91

x = 27°

angle u = 89° ( corresponding angles)

angle ptu = 89 + 27

= 116°

Write a 5 sentence Summary:

Describe the transformation that exist a negative is multiplied outside of the function.

Answers

Answer:

The negative sign outside the absolute value function causes a few different things when multiplied. When a negative is multiplied outside of the function, the transformation that exists will be a vertical reflection.  A horizontal shift to the left 1 unit will happen because of g(x)=f(x+1). The graph will make a vertical shift down 2 units because of g(x)=f(x)−2. The value of (a) would be -1 and since it is less than 1, and it causes the graph to be wider because of vertical compression. Placing a minus sign outside absolute value bars gives you a negative result.

Plz help! Solve systems of Equations by substitution
y = 6x -11
-2x - 3y = -7

Answers

Answer:

x = 2

y = 1

Step-by-step explanation:

1) Re-arrange

(Solving for y)

-2x -3y = -7    -->  x3

6x - y = 11    -->  x1

-6x -9y = -21

6x -y = 11

-9y = -21

-y = 11

(-9y + -y) = (-21 + 11)

-10y = -10    

y = -10/-10

y = 1

2) Substitute

6x - 1 = 11

6x = 11 + 1

6x = 12

x = 12/6

x = 2

Answer: x = 2, y = 1

Step-by-step explanation:

Rearrange the second equation so it just works a little easier for you:

-2x - 3y = -7

rearranged to make y (with its constant) the subject:

3y = 7 - 2x

So we know what y equals. The question tells us y = 6x - 11. So substitute those values into the rearranged equation.

3y = 7 - 2x   becomes:

3(6x - 11) = 7 - 2x

because as stated in the question, y = 3x - 11.

Expand the brackets on the left-hand side:

18x - 33 = 7 - 2x

Rearrange to collect like terms:

18x = 7 + 33 - 2x

18x = 40 - 2x

18x + 2x = 40

20x = 40

x = 40/20

x = 2.

So now we know the value of x.

Let's input our new found value of x into one of the given equations, such as y = 6x - 11.

y = (6 * 2) - 11

y = 12 - 11

y = 1.

So y = 1.

You can test this by inputting these values into the other equation, for assurance.

-2x - 3y = -7 becomes:

(-2 * 2) - (3 * 1) = -7

(-4) - 3 = -7

-7 = -7

rewrite the equation in Ax + By = C form. use integers for A, B, and C. y - 6 = -3 (x + 5)

3x + y - 6 = -15

There is still controversy about whether or not Pluto should be considered a planet. Although planets are mainly defined by their orbital path (the condition that prevented Pluto from remaining a planet), the issue of size is something to consider. The table below lists the planets, including Pluto, and their approximate diameters in meters.


Planet Approximate Diameter (m)

Mercury 4.88 × 10^6

Venus 1.21 × 10^7

Earth 1.28 × 10^7

Mars 6.79 × 10^6

Jupiter 1.43 × 10^8

Saturn 1.2 × 10^8

Uranus 5.12 × 10^7

Neptune 4.96 × 10^7

Pluto 2.3 × 10^6

Answers

Answer:

  b) 62

Step-by-step explanation:

When all the numbers are in scientific notation, as these are, the numbers with the smallest exponent are smaller. If numbers have the same exponent, the number with the smaller mantissa is smaller.

a) least-to-greatest diameter, the order is ...

  Pluto, Mercury, Mars, Venus, Earth, Neptune, Uranus, Saturn, Jupiter

__

b) The ratio of diameters of Jupiter and Pluto is ...

  (1.43×10^8)/(2.3×10^6) = 6.2×10^1 = 62

Jupiter's diameter is about 62 times that of Pluto.

A cable company technician gave 3:00PM to 7:00PM as his arrival time. The arrival time is uniformly distributed. What is the probability that he arrives exactly at 4:00PM

Answers

I believe the answer is 1/240 but I am not sure

The probability that the technician arrives exactly at 4:00 pm is 1/5.

What is probability?

Probability is the chance of occurring a certain event out of the total no. of events that can occur in a given context. The probability of an event is always greater than equal to zero and less than equal to one.

If we distribute arrival time uniformly in terms of hours the no. of sample space N(s) = 5.     (3:00pm, 4:00pm, 5:00pm, 6:00pm, 7:00pm).

∴ The probability that he arrives exactly at 4:00 pm is,

= 1/5.

The probability of arriving at 4:00 pm is 1/5.

A bike wheel is 26 inches in diameter. What is the bike wheel's diameter in millimeters (1 inch = 25.4 millimeters)?

Answers

Answer:

660.4 mm

Step-by-step explanation:

Since 1 inch is equal to 25.4 millimeters, we can multiply 25.4 by 26 to see how many millimeters 26 inches is. You can also think of this as a proportion:

26:x = 1:25.4

26.4 times 26 is equivalent to 660.4, so we can conclude that 26 inches are equivalent to 660.4 millimeters.

him or her how to divide 2/3 by 1/6

Answers

9514 1404 393

Answer:

invert and multiply, oruse a common denominator

Step-by-step explanation:

There are two ways you can divide 2/3 by 1/6.

1) Division by a number is the same as multiplication by its reciprocal. The reciprocal of a fraction is the fraction obtained by swapping the numerator and denominator. So, division by 1/6 is the same as multiplication by 6/1.

  2/3 ÷ 1/6 = 2/3 × 6/1

The result of this multiplication is the product of the numerators divided by the product of the denominators:

  2/3 × 6/1 = (2×6)/(3×1) = 12/3 = 4

__

2) The fractions can be expressed with the same denominator. Then their quotient is the quotient of their numerators.

  2/3 = 4/6

  2/3 ÷ 1/6 = 4/6 ÷ 1/6 = 4 ÷ 1 = 4

B(5, 1). Find the equation of the line that contains the given segment.
The line segment is AB.
The equation is y =

Answers

Step-by-step explanation:

the equation is

y = ax + b

a is the slope of the line. this is the ratio y/x indicating how many units y changes, when x changes a certain number of units.

so, when we go from A to B, x changes 2 units (from 3 to 5), and y changes -4 units (from 5 to 1).

so the slope is -4/2 = -2

now or equation looks like

y = -2x + b

to get b we use one of the points in the equation. e.g. B

1 = -2×5 + b = -10 + b

b = 11

so, our full equation is

y = -2x + 11
