$1006.85 would be saved per month if the 8 watts LED replaced the 100 watts bulbs.
What is an equation?An equation is an expression that shows the relationship between two or more variables and numbers.
Amount of energy for the 100 watt bulb = 8 * 100 watt * 8 hr * 30 days =192000 Wh = 192 kWh
Amount of energy for the 8 watt bulb = 8 * 8 watt * 8 hr * 30 days = 15360 Wh = 15.36 kWh
The cost saved in a month = $5.7 * (192 - 15.36) = $1006.85
$1006.85 would be saved per month if the 8 watts LED replaced the 100 watts bulbs.

Find the Unit Price for each bottle of conditioner. Which bottle of hair conditioner is the best buy?
8 oz for $1.49
12 oz for $2.29
15 oz for $2.75
20 oz for $3.89
Answer:
D.
Step-by-step explanation:
We know that to find unit price, we divide the unit in the numerator by the quantity in the denominator.
For the first option, we must put $1.49 as the numerator and 8 as the denominator. It will then look like this:
[tex]\frac{1.49 / 8 }{8 / 8\\}[/tex] Then we must divide 1.49 by 8. This will get us $0.18625.For our second option, we must put $2.29 as the numerator, and 12 as the denominator. It will look like this:
[tex]\frac{2.29 / 12 }{12 / 12\\}[/tex] Then we must divide 2.29 by 12. This will get us $0.19083 (rounded)For our third option, we must put $2.75 as the numerator, and 15 as the denominator. It will look like this:
[tex]\frac{2.75 / 15 }{15 / 15}[/tex]Then we must divide 2.75 by 15. This will get us $[tex]0.18333[/tex] (rounded)For our final option, we must put $3.89 as the numerator, and 20 as the denominator. It will look like this:
[tex]\frac{3.89 / 20 }{3.89 / 20}[/tex]Then we must divide 3.89 by 20. This will get us $0.1945 (rounded)Therefore, the last option is the best buy because $0.18625 > $0.18333.

Answer:
m∠WVZ=90°
m∠XVW=90°
Step-by-step explanation:
m∠WVY=m∠WVZ+m∠ZVY
180°=9x-15°+90°
180°=9x+75°
180-75=9x
105°=9x
⇒x = [tex]\frac{35}{3}[/tex]
So. m∠WVZ is
[tex]=9(\frac{35}{3})-15=3\times35-15\\=105-15=90[/tex]
m∠WVZ=90°
and same will be the m∠XVW
m∠XVZ=m∠XVW+m∠WVZ
180°=m∠XVW+90°
m∠XVW=180°-90°
m∠XVW=90°
Two dice are tossed 396 times. How many times would you expect to get a sum of 3?
Using proportions, it is found that you would expect to get a sum of 3 22 times.
What is a proportion?A proportion is a fraction of a total amount, and the measures are related using a rule of three.
When two dice are rolled, there are 36 total outcomes. 2 of them, (1,2) and (2,1), result in a sum of 3, hence the proportion is given by:
p = 2/36 = 1/18.
Out of 396 tosses, the expected value is given by:
E = 1/18 x 396 = 22.

A local charity holds a carnival to raise money. In one activity, participants make a $3 donation for a chance to spin a wheel that has 10 spaces marked with the values 0, 1, 2, 5, and 10. The participant wins the dollar amount marked on the space on which the wheel stops. Let X be the value of a random spin. The distribution of X is given in the table. What is the mean?
Answer:The median of the distribution is (first option)
1
Step-by-step explanation:
The values on the given table are presented as follows;
Value of spin: 0,1,2,5,10
Probability: 0.4,0.2,0.2,0.1,0.1
To find the median, we calculate the cumulative probabilities to find the value of the spin art which the cumulative probability is 0.5 as follows;
Cumulative probability, starting from the left, is therefore;
Probability for spin of 0, 0.4 + Probability for spin of 1, 0.2 = 0.6
Therefore, given that the probability of 0.5 occurs within the Value of Spin 1, the median of the probability distribution is 1
The solution is : The median of the distribution is (first option) 1
What is median?In statistics and probability theory, the median is the value separating the higher half from the lower half of a data sample, a population, or a probability distribution. For a data set, it may be thought of as "the middle" value.

The consecutive angles of a parallelogram are________?
Answer:
supplementary
Consecutive angles are supplementary (A + D = 180°). If one angle is right, then all angles are right. The diagonals of a parallelogram bisect each other. Each diagonal of a parallelogram separates it into two congruent triangles.
Answer:
Supplementary
Step-by-step explanation:
The consecutive angles of a parallelogram are supplementary.
Two angles that add up to 180° are called supplementary angles.
This can be proven by creating a parallelogram and extending all segments to create two parallel lines transversing another set of two parallel lines.
I drew a diagram of this shape and considering that all the opposite lines are parallel, the central shape is a parallelogram.
Looking at the diagram attached, we know that the angle of a straight line is 180° (represented by the yellow of Angle 1 and the pink angle next to it) All angles of the same color are congruent by angle theorems consisting of corresponding and vertical angles.
If pink is x, and yellow is y, then we can say that x + y = 180°
So, therefore we can say that the consecutive angles of the parallelogram (Angle 1 and Angle 2) sum up to 180°, because they are made up of one pink angle and one yellow angle ( x and y )

Answer:
30 inches
Step-by-step explanation:
In equilateral triangle all sides are equal. One side of the triangle EB is also the side of a square.
So, all the sides of the square is 6 inches
Perimeter = sum of all sides
= AB + BC + CD + DE + EA
= 6 + 6 + 6 + 6 + 6
= 5*6
= 30 inches
Answer:
Here,
length of the square BCDE(l)= 6 inches
Also,
length of the equilateral triangle ABE(l)=6 inches
Lastly, Perimeter of figure ABCDE= 5*6
=30 inches
or,Perimeter of the figure ABCDE also=
AB+BC+CD+DE+EA
=6+6+6+6+6
=30inches
Step-by-step explanation:
We know,
length DC of the square BCDE(l)=6inches
So,
DC=BC=BE=DE (All sides of a square are equal)
Again,
length BE of the equilateral triangle ABE=6inches
So,
BE=AB=AE (All sides of a equilateral triangle are equal)
Therefore, Perimeter of figure ABCDE=
AB+BC+CD+DE+EA or, 5*6
(perimeter means to sum all the outer sides a given polygon, in this case it's a Pentagon)

Ray HJ is the angle bisector of angle GHI. The measure of angle IHJ is 32°. What is the measure of angle GHJ?
a: 64°
b: 16°
c: 32°
d: 0.5°
Answer:
c) 32°
Step-by-step explanation:
The bisector of an angle is the line or line segment that divides the angle into two equal parts. So Ray HJ divides ∠GHI into 2 equal parts.
Therefore, ∠GHJ = ∠IHJ
As we are told that ∠IHJ = 32° then ∠GHJ = 32°
To find the missed spaces
Step-by-step explanation:
all coefficients are integers, the rational zeros theorem can be applied.
that means each rational solution ("root") x = p/q, written in most simplified terms so that p and q are relatively prime, can be found for the polynomial
an×x^n + an-1×x^(n-1) + ... + a1×x + a0
p is an ± integer factor of the constant term a0, and
q is an ± integer factor of the leading coefficient an.
in our case here
an = a4 = 1
a0 = 8
the only factor for 1 is ±1.
the factors for 8 are
±1, ±2, ±4, ±8
so, we get
1/1, 2/1, 4/1, 8/1, -1/1, -2/1, -4/1, -8/1, 1/-1, 2/-1, 4/-1, 8/-1, -1/-1, -2/-1, -4/-1, -8/-1
that leaves us with the different values of
1/1, 2/1, 4/1, 8/1, -1/1, -2/1, -4/1, -8/1
sorted from smallest to largest
-8/1, -4/1, -2/1, -1/1, 1/1, 2/1, 4/1, 8/1

Solving system of equations:
y = -x + 4 ----------(I)
y = x - 2 -----------(II)
Add equation (I) & (II). So, x will be eliminated and we can find the value of y.
(I) y = -x + 4
(II) y = x - 2 {Now add}
2y = 2
Divide both sides by 2
y = 2/2
y =1
Substitute y = 1 in any of the equations. Here, we are substituting in equation (II)
1 = x - 2
1 + 2 = x

What is the area of the triangle figure?
The area of the triangle is equal to 12 mm².
Area of triangle
The area of a triangle is given by the formula:[tex]A=\frac{bh}{2}[/tex], where:
b= length of the base;
h=height
STEP 1 - Find the dimensions for the base and the height of the triangle.From the figure, it is possible to see that h= base of rectangle - 4 mm. Then, the height of the triangle(h)= 10-4=6 mm.
You can see that the sum of the base of the triangle with the height of the rectangle is equal to 12 mm. The figure also shows that the height of this rectangle is equal to 8 mm. Thus, the base of the triangle(h)= 12-8=4 mm.
STEP 2 - Find the area of the triangle.
From step 1:
b= length of the base= 4
h=height=6
Therefore, the area of the triangle - [tex]A=\frac{bh}{2}=\frac{4 * 6}{2}=\frac{24}{2} =12 mm^2[/tex].
