In 1 h the minute hand on a clock moves through a complete circle, and the hour hand moves through 1/12
of a circle.Through how many radians do the minute hand and the hour hand move between 1:00 p.m. and 6:45 p.m. (on the same day)?
9514 1404 393
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
_____
Additional comment
Maybe you're asking for the separate motions.
minute hand: 2π×5.75 = 11.5π radians
hour hand: (π/6)×5.75 = 23π/24 radians

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

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
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)?
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
9514 1404 393
Answer:
invert and multiply, oruse a common denominatorStep-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

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

a. Name the planets (including Pluto) in order from smallest to largest.
b. Comparing only diameters, about how many times larger is Jupiter than Pluto?
9514 1404 393
Answer:
a) Pluto, Mercury, Mars, Venus, Earth, Neptune, Uranus, Saturn, Jupiter
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.

Write a 5 sentence Summary:
Describe the transformation that exist a negative is multiplied outside of the function.
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.

- 6/5 - 1/3 = 23/15. (Common denominator = 15)

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

The endpoints of a side of rectangle ABCD in the coordinate plane are at A(3,5) and
B(5, 1). Find the equation of the line that contains the given segment.
The line segment is AB.
The equation is y =
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
