Step-by-step explanation:
Energy can be defined as the ability (capacity) to do work and it's measured in Joules. The various forms of energy are solar energy, chemical energy, thermal energy, wind energy, nuclear energy, electrical energy, etc.
Power can be defined as the energy required to do work per unit time.
Mathematically, it is given by the formula;
[tex] Power = \frac {Energy}{time} [/tex]
Energy consumption is the total amount of power used by an electronic device per unit time and it's measured in Watt-hour or Kilowatt-hour.
Mathematically, it is given by the formula;
[tex] Energy = power * time [/tex]
Generally, the most economic way to lessen electric consumption is by ensuring only the important electrical appliances are used at all times.
2. Given the following data;
Previous reading = 2156 KWh
Present reading = 2268 KWh
To find how many kilowatt-hour was consumed;
Energy consumption = present reading - previous reading
Energy consumption = 2268 - 2156
Energy consumption = 112 KWh
3. Given the following data;
Previous reading = 5512 KWh
Present reading = 5623 KWh
To find the electrical consumption of Falogme Family;
Electrical consumption = present reading - previous reading
Electrical consumption = 5623 - 5512
Electrical consumption = 111 KWh

Answer:
If we have a figure translated, all the points are translated by the same amount. So, to find the translation, we can look at a single vertex of one of the figures and see how many units it moved in each axis.
a) Let's look at points B and B'.
B = (-3, 4)
B' = (-1, 3)
The translation will be given by:
B' - B
(-1, 3) - (-3, 4) = (-1 -(-3), 3 - 4) = (1 + 3, -1) = (2, - 1)
Then, each point (x, y) in the original figure, is translated to (x + 2, y - 1)
Then the correct point is C.
b) Let's look at points B and B' again.
We can see that:
B = (1, 6)
B' = (6, -2)
Again, the translation is given by:
B' - B
(6, -2) - (1, 6) = (6 - 1, -2 - 6) = (5, - 8)
Then, any point (x, y) in the original figure, is translated to (x + 5, y - 8)
Then the correct option is C

A lock has a 3-number code made up of 16 numbers. If none of the numbers are allowed to repeat, how many different ways can you choose three different numbers in order for a unique code?
Answer:
137
Step-by-step explanation:
The number of ways we can choose three different numbers in order for a unique code for this case is 2730
What is Combination?A combination is a technique to determines the number of possible arrangements in a collection of items where the order of the selection does not matter.
We can use combinations for this case,
Total number of distinguishable things is m.
Out of those m things, k things are to be chosen such that their order doesn't matter.
This can be done in total number of ways,
⇒ [tex]^{m} C_{k} =[/tex] m! / (m - k)! k!
If the order matters, then each of those choice of k distinct items would be permuted k! times.
So, total number of choices in that case would be:
⇒ [tex]^{m} P_{k} =[/tex] m! / (m - k)!
This is called permutation of k items chosen out of m items (all distinct).
Given that:
The considered lock as a 3 number code
There are 15 numbers available.
None of the number can repeat.
In a lock, the order of the way numbers are arranged matters.
Because of no repetition allowed, we can simulate this situation as:
The number of ways we can choose 3 numbers out of 15 numbers with order = The number of different ways we can choose three different numbers in order for a unique code.
And we have:
The number of ways we can choose 3 numbers out of 15 numbers with order is,
⇒ [tex]^{m} P_{k} =[/tex] m! / (m - k)!
⇒ [tex]^{15} P_{3} =[/tex] 15! / (15 - 3)!
= 15! / 12!
= 2730
Thus, The number of ways we can choose three different numbers in order for a unique code for this case is 2730

Jamie needs to determine the distance across a river. She selects a rock, R. on the opposite river bank. She finds a tree, T. on her side of the river such that RT is perpendicular to the river: Next, Jamie walks 50 yards down the river from the tree, T. to a spot, C. Using a compass that she made from two sticks, she measures TCR. She then walks from C in a direction that makes the same angle as ZTCR with the river bank on her side of the river. She keeps walking in that direction until she sees the tree and the rock in a straight line from her position. She marks this point B and then paces from B to T to measure the distance from point B to the tree. If BT turns out to be 75 yards, what is RT, the distance across the river?
9514 1404 393
Answer:
RT = 75 yards
Step-by-step explanation:
Triangle TCB is congruent to triangle TCR by ASA. (Side TC is between angles T and C.)
Then RT = BT = 75 yards.

The polynomial equation x3- 4x2 + 2x+ 10 = x2 - 5x-3 has complex roots 3+2i. What is the other root? Use a graphing
calculator and a system of equations.
Answer:
Step-by-step explanation:
Given Equation:
x^3- 4x^2 + 2x+ 10 = x^2 - 5x-3
which simplifies to
x^3- 5x^2 + 7x+ 13 = 0
Given one of the roots is x = 3x+2i, the conjugate is therefore x = 3-2i.
The product is real, (x-3+2i)(x-3-2i) = x^2-6x+13
The other root can therefore be obtained by long division
(x^3- 5x^2 + 7x+ 13)/(x^2-6x+13) = x+1, or x=-1
Therefore the three roots are:
{x=3-2i, x=3+2i, x=-1 }
An animal shelter provides shelter for dogs and cats. The animal shelter currently has a total of 117 animals. If the number of cats is 3 more than 5 times the number of dogs, how many dogs and cats are currently at the animal shelter?
Answer:
98 cats and 19 dogs
Step-by-step explanation:
cat = c
dog = d
The animal shelter currently has a total of 117 animals
c + d = 117
c = 117 - d
the number of cats is 3 more than 5 times the number of dogs
c = 3 + 5d
subtitute c
117 - d = 3 + 5d
117 - 3 = 5d + d
114 = 6d
6d = 114
d = 114/6 = 19
so, the cat is 117-19 = 98
Which statement correctly explains how ladies could find a solution to solution to the following system of linear equations using elimination?
Given:
The system of equations is:
[tex]-4g-15h=-17[/tex]
[tex]-g+5h=13[/tex]
To find:
The correct statement that explains the solution process.
Solution:
We have,
[tex]-4g-15h=-17[/tex]
[tex]-g+5h=13[/tex]
To eliminate the variable g, we need same coefficients of g having opposite signs.
The coefficient of g in first equation is -4 and the coefficient of g in bottom equation is -1. If we multiply the bottom equation by -4, then we get 4 as a coefficient of g.
[tex]4g-20h=-52[/tex] [(i)×(-4)]
After that we can add both equation to eliminate the variable g and then we can solve to h.
She can multiply the bottom equation by -4 and then add the equations to solve for h.
Therefore, the correct option is A.

Answer:
Perimeter you add up all the sides. If it is a horizontal or vertical line, you just write those values for the side lengths. For the slanted one, I would use pythagorean theorem to solve it.
Step-by-step explanation:
If we make a right triangle using vertical and horizontal lines. We will find that a = 6, and b = 12. Find the square root of the sum of a squared plus b squared. That will tell you C. Then add C to the other 3 sides and that will give you the perimeter.
Write an equation of the line in point slope form given the information below slope= 7 point (1,4)
Answer:
y-4=7(x-1)
Step-by-step explanation:
y-y1=m(x-x1)
y-4=7(x-1)
The equation of the line with a slope of 7, passing through the point (1,4), in point-slope form is y = 7x - 3.
To write the equation of a line in point-slope form, we use the formula:
y - y₁ = m(x - x₁)
where m represents the slope of the line and (x₁, y₁) represents the coordinates of a point on the line.
In this case, the given slope is 7 and the point (1,4) lies on the line. Plugging in the values into the formula, we have:
y - 4 = 7(x - 1)
Simplifying the equation, we can distribute the 7:
y - 4 = 7x - 7
To isolate y, we can add 4 to both sides of the equation:
y = 7x - 7 + 4
y = 7x - 3

What is the domain of the function graphed below?
Answer:
x < 7
Step-by-step explanation:
the domain is the number range or interval of x the function is defined for to generate a y-value.
the graph shows that the y-values continue with x-values to the right up to but not including 7 (the empty dot says "excluding"). and with x- values to the left to negative infinity.
x=-1 is not a problem, because while for the left part of the function it is not included, but for the right part it is.
so, it is fully defined for all x < 7.
Jaxon is traveling from Portland, Oregon to Denver, CO. If he were traveling by car, he would drive 1000 miles east and 575 miles south. What distance, to the nearest tenth of a mile, would he travel if he took a direct flight from Portland to Denver?
1153.5 miles
1575 miles
425 miles
818.2 miles
Answer:
1153.5 miles (first answer choice)
Step-by-step explanation:
'1000 miles east' is the change in x ('the run'), and '575 miles south' is the change in x (the 'rise'). Since these two vectors form a right angle, we can immediately apply the Pythagorean Theorem without worrying about signs:
d = √(1000² + 575²) = 1153.5 miles (first answer choice)

3 -4. Litros d jugo de frutilla 1 y 1-2 litro de jugo de manzana 1-8 litro de jugo de limón Y 1 y 1-2 litro de agua .Cuántos litros de jugo preparo la mamá??
Answer:
La madre hizo en total 2 y 3/8 litros de jugo.
Step-by-step explanation:
Sabemos que preparó:
3/4 litros de jugo de frutilla = 3/4 L
1 y 1/2 litro de jugo de manzana = (1 + 1/2) L
1/8 litro de jugo de limón = 1/8 L
1 y 1/2 litro de agua = (1 + 1/2) L
¿Cuántos litros de jugo preparó la mamá?
Simplemente debemos sumar los distintos volúmenes de jugo escritos arriba (el de agua no, pues solo nos pregunta cuantos litros de jugo se prepararon)
Total de jugo = 3/4 L + (1 + 1/2) L + 1/8 L
Para completar esta suma, separamos los números enteros de los racionales:
Total de jugo = 1 L + ( 3/4 + 1/2 + 1/8) L
Para resolver la suma dentro del paréntesis, debemos tener todos los números con el mismo denominador.
Recordar que si multiplicamos el numerador y el denominador por el mismo número, entonces el número racional no cambia.
Como el denominador más grande dentro del paréntesis es 8 (que tambien es multiplo de los otros dos), tratemos de reescribir los otros dos números de tal forma que su denominador también sea 8:
Total de jugo = 1 L + ( (2/2)*(3/4) +(4/4)*(1/2) + 1/8) L
= 1 L + (6/8 + 4/8 + 1/8) L
= 1 L + (11/8) L
podemos reescribir el segundo termino como:
= 1L + (8 + 3)/8 L
= 1L + (8/8) L + (3/8) L
= 1L + 1L + 3/8 L
= 2L + 3/8 L
La madre hizo en total 2 y 3/8 litros de jugo.

A map has a scale of 1:200000 How far is it from Belfast to Larne in Km if the distance on the map is 7.8cm
Answer:
15.6km
Step-by-step explanation:
Given the map scale 1:200000
1cm on the map represents 200000 cm on ground or in actual distance
Hence, if distance from Belfast to Larne is 7.8vm on map ;
Actual distance will be :
7.8 * 200000 = 1560000 cm
Converting to km :
Recall :
1000 m = 1km
100 cm = 1 m
Hence,
100000 cm = 1km
Therefore, (1560000 / 100000) km
= 15.6km
Hence, distance between Belfast and Larne is 15.6km
