Water main valves should be located at frequent intervals in a grid system.
What is a water valve?
The flow and temperature in pipes and plumbing fittings are controlled by water valves. The valves regulate steady flow and volume when they are correctly placed and used. Water valves are made of brass, plastic, stainless steel, bronze, cast iron, and galvanised pipe, among other materials.
The master cutoff valve for the house will typically feature a wheel (a gate valve) or a straight handle (ball valve). The wheel on gate valves (seen on the right) is turned clockwise until the water is shut off. To turn off the water, turn the handle of a ball valve a quarter turn in the opposite direction. Every house has two main water shutoff valves: one inside and one near the intersection of your property and the street.

Using it's concept, the probability of at least 1 red face upper most is 17/18 = 0.9444 = 94.44%.
What is a probability?A probability is given by the number of desired outcomes divided by the number of total outcomes.
For each cube, the probability of no red faces is:
Cube A: 1/6.Cube B: 3/6 = 1/2.Cube C: 4/6 = 2/3.Hence the probability of no red faces in anu cube is:
1/6 x 1/2 x 2/3 = 1/18.
Which means that the probability of at least 1 red face is given by:
1 - 1/18 = 17/18 = 0.9444 = 94.44%.

HELP ME SOLVE PLEASEEEE
Answer: It is m<U = 60 and m<V = 120 (x = 20)
Step-by-step explanation:
1. We know that these 2 angles are supplementary, which means both adds up to 180 degrees.
2. So first, we do this:
3x + 2(m<U) = 180
2a. We do this to find m<U
3. We can also notice that 3x is m<U, so substituting m<U with 3x makes sense. 3x + 2(3x) = 180
4. We then simplify:
3x + 6x = 180
9x = 180
5. We will then divide:
x = 20
6. With the new found info, we substitute x with 20:
m<U = 3(20)
m<V = 2(3(20))
7. Doing the math, it becomes:
m<U = 60
m<V = 120
(i) You can add both up if you want to make sure, but it is correct

First Options:

Second Options:

Third Options:
Numbers of hours of sleep
Genre of the movies
Actors in the movies
There is no relationship between the number of movies and the number of sleep hours.
What is a relationship?It is always a thing of importance to show data by the use of a scatter plot. The scatter plot must always have two axes. The vertical (y axis ) and the horizontal (x axis). It is always common to plot the independent variable on the x axis and the dependent variable on the y axis.
The scatter plot thus represented shows how one variable is related to another. In this case, we are trying to obtain how the number of sleep hours tend to be related with the number of movies and this has been shown on the scatter plot that is shown in the question above.
It is clear from the statements in the question that the line of best fit would show that as the number of movies remained constant, the number of sleep hours decreased. This now implies that there is no relationship between the number of movies and the number of sleep hours.

The perimeter of the triangle formed by the points B(7,-9), C(7,-2) and D(0,0) is 25.68 square units.
Perimeter is defined as the distance or the enclosed path that surrounds the 2-D shapes or polygon. The perimeter of a triangle is the sum of all the three sides of a triangle.
The perimeter of a triangle formed by the points B(7,-9), C(7,-2) and D(0,0) can be determined by finding the distance between two points.
The distance between two points A(x1,y1) and B(x2,y2).
√[(x2-x1)²+(y2-y1)²]
Therefore, BC = √(7-7)²+(-2+9)²
BC = √49
BC = 7 square units.
and CD = √(0-7)²+(0+2)²
CD = √53
CD = 7.28 square units.
and DB = √(7-0)²+(-9-0)²
DB = √130
DB = 11.40 square units.
Therefore, perimeter of triangle formed from given points is BC+CD+DB = 7+7.28+11.40 = 25.68 square units.

A rocket flies 10 km vertically, then 20 km at an angle of 15° to the vertical and finally 60 km at an angle of 26° to the vertical. Calculate the vertical height of the rocket at the end of the third stage.
The vertical height of the rocket at the end of the third stage is 83.2 km.
We are provided that the rocket travels first 10 km vertically up (OA), then the rocket travels for 20 km (AC) at an angle of 15° from point A.
Let rocket travels 'a' distance vertically up(AB) during this,
then, rocket travels for travels for 60 km (CD) at an angle of 26° from point C.
Let rocket travels ' b' distance vertically up (BX) during this.
So,
Total Vertical Height Covered = 10 + a + b
So, According to diagram
In ΔABC
[tex]cos \ 15[/tex]° [tex]= \frac{a}{20}[/tex]
[tex]\\a = 20 * cos 15[/tex]° = 19.32km
In ΔCDE
[tex]cos \ 26[/tex]° [tex]= \frac{b}{60}[/tex]
[tex]\\b = 60 * cos 26[/tex]° = 53.9km
Since,
Total Distance = 10 + a +b
Total Distance = 10 + 19.32 + 53.9
Total Distance = 83.2 km

A bag contains 3 red marbles, 5 blue marbles and 4 green marbles. If
two marbles are drawn out of the bag, what is the exact probability
that both marbles drawn will be red?
+-
Answer:
Submit Answer
the probability of drawing 2 red marbles from the bag will be 0.0455.
Number of Red marbles = 3
Number of blue marbles = 5
Number of green marbles = 4
Total marbles = 3 + 5 + 4 = 12
Probability of drawing 2 red marbles from the bag will be:
P = 3 / 12 × 2 / 11
P = 6 / 132
P = 3 / 66
P = 1 / 22
P = 0.0455

If angle 5 is 120 degrees, find the value of <8
Answer:Answer:
The measurement of the angle is 60
Step-by-step explanation:
The two blue lines are straight and parallel lines. The sum of the angles on a straight line is 180 degrees. Angle 5 and angle 6 are on a straight line. Therefore
Angle 5 + angle 6 = 180
If angle 5 is 120 degrees, then
Angle 6 = 180 - 120 = 60 degrees.
