Step-by-step explanation:
Parents sometimes yell at their children for leaving the light on in their bedroom when they aren't in the room. If the child's room is lit with two 10 watt bulbs for one extra hour a day for everyday of the year (365), and the cost of energy is $0.068 per kilowatt*hour (kWh), how much money is wasted on lighting that isn't being used, to the nearest cent.
Answer:
50 cent
Step-by-step explanation:
Given that :
Cost of energy = $0.068 per kilowatt-hour (kWh)
Number of bulbs = two 10 watt bulbs
Converting the power of the bulb to kilowatt :
2 * 10watt = 20 watt
1000 watt = 1 kilowatt
20 watt = x
1000x = 20
x = 20/1000
x = 0.02 kW
Cost of Energy consumed by bulb 1 hour for 365 days :
0.02kW * 1 * 365 * $0.068 = $0.4964
$0.4964 to cent
100 cent = $1
$0.4964 * 100 = 49.64 cent
49.64 = 50 (nearest cent)

Step-by-step explanation:
The length of a rectangle is three times its width.
If the perimeter of the rectangle is 56 yd, find its area.
Answer:
147 yards
Step-by-step explanation:
Use a system of equations
Let x be length of rectangle and y be width of rectangle
x = 3y
2x + 2y = 56
Substitute x = 3y into second equation, we have 2(3y) + 2y = 56. Combine like terms and we have 8y = 56. y = 7.
Substituting y = 7 into the first equation, we have x = 3(7), and x = 21.
Area is length times width, so area is 21 * 7 = 147
Answer:
area= 147 yd
Step-by-step explanation:
l= 21 yd
w= 7 yd
Formula: a=lxw (area=length x width)
a=21 x 7
21 x 7=147 yd

The local nursery is waiting for its spring annuals to be delivered, and 20% of the plants ordered are petunias. If the first truck contains 120 plants packed at random, what is the probability that no more than 30 plants are petunias?
Answer: 0.9147
Step-by-step explanation:
Given: 20% of the plants ordered are petunias.
Let p = 20% = 0.2
Sample size: n = 120
If they follow normal distribution, then mean = np = 120x 0.2 = 24
Standard deviation = [tex]\sqrt{n p(1-p)}=\sqrt{120\times0.2\times.8}[/tex]
[tex]=\sqrt{19.2}\\\\ =4.38[/tex]
The probability that no more than 30 plants are petunias : [tex]P(\dfrac{X-\mu}{\sigma}\leq \dfrac{30-24}{4.38})[/tex]
[tex]=P(Z<1.37)= 0.9147[/tex]
Hence, the probability that no more than 30 plants are petunias = 0.9147

What is the fundamental principle of multiplication?Multiplication is the mathematical operation that is used to determine the product of two or more numbers. If an event can occur in m different ways and if following it, a second event can occur in n different ways, then the two events in succession can occur in m × n different ways.
We are given that lottery game called Quinto is played by choosing five numbers each, from 0 through 9
Therefore, we are asked to find the number of possibilities.
10 x 10 x 10 x 10 x 10
=100,000
Thus, there are 100,000 number
This means that from 0 through 9 there are 10 possibilities.
Hence, A lottery game called Quinto is played by choosing five numbers each, from 0 through 9, there are 10 possibilities

Neena is listening to a song. It has a consistent beat. She counts 11 beats in
5 seconds. What is the constant of proportionality for the relationship of beats
to minutes? Show your work.
Answer:
132
Step-by-step explanation:
First, find how many beats are in a minute by creating a proportion:
[tex]\frac{11}{5}[/tex] = [tex]\frac{x}{60}[/tex]
Cross multiply and solve for x:
5x = 660
x = 132
So, there are 132 beats in one minute.
This means the constant of proportionality is 132.
The proportional relation is y= 2.2x
What is proportion?In general, the term "proportion" refers to a part, share, or amount that is compared to a total.
According to the concept of proportion, two ratios are in proportion when they are equal.
A mathematical comparison of two numbers is called a proportion. According to proportion, two sets of provided numbers are said to be directly proportional to one another if they increase or decrease in the same ratio. "::" or "=" are symbols used to indicate proportions.
Given:
Neena counts 11 beats in 5 seconds
So, x=11 and y=5
Using the proportionality
y = k x
k= y/x
k= 11/5
k= 2.2
Hence, the proportional relation is y= 2.2x

What is the perimeter of the composite figure? Round to the nearest tenth
Answer:
123.8 units
Step-by-step explanation:
The vertices of the polygon has been labelled ABCDEF, as shown in the diagram attached below.
Perimeter of the Polygon = [tex] \overline{AB} + \overline{BC} + \overline{CD} + \overline{DE} + \overline{EF} + \overline{FA} [/tex]
[tex] \overline{AB} [/tex] = |-12 - 24| = |-36| = 36 units
[tex] \overline{BC} [/tex]: calculate the distance between B(24, 16) and C(15, 3) using the distance formula.
[tex] \overline{BC} = \sqrt{(x_2 - x_1)^2 + (y_2 - y_1)^2} [/tex]
[tex] \overline{BC} = \sqrt{(24 - 15)^2 + (16 - 3)^2} [/tex]
[tex] \overline{BC} = \sqrt{(9)^2 + (13)^2} [/tex]
[tex] \overline{BC} = \sqrt{81 + 169} = \sqrt{250} [/tex]
[tex] \overline{BC} = 15.8 units [/tex]
[tex] \overline{CD} [/tex] = |6 - 15| = |-9| = 9 units
[tex] \overline{DE} [/tex] = |3 -(-12)| = |-15| = 15 units
[tex] \overline{EF} [/tex] = |-12 - 6| = |-18| = 18 units
[tex] \overline{FA} [/tex] = |18 -(-12)| = 30 units
Perimeter = 36 + 15.8 + 9 + 15 + 18 + 30 = 123.8 units

49-3m=4m+4 please help
Answer:
m = 45/7
Step-by-step explanation:
move terms :
49 - 3m - 4m = 4
-3m - 4m = 4 - 49
collect like terms
-7m = 4 - 49
-7 = -45
divide both sides of the equation by -7
= m = 45/7
Answer:
m = 6.43
Step-by-step explanation:
49 - 3m = 4m + 4
1. subtract 4 from both sides
45 - 3m = 4m
2. add 3m to both sides
45 = 7m
3. divide by 7
6.428571429 = m

The components of a vector are Ax = –10 units and Ay = 8 units. What angle does this vector make with the positive x axis? g
Answer:
This vector make an angle of 141° with the positive x axis
Step-by-step explanation:
Refer the attached figure
Components of vector :
[tex]A_x=-10 \\A_y = 8[/tex]
We are supposed to find What angle does this vector make with the positive x axis
[tex]tan \theta =\frac{A_y}{A_x}\\tan \theta =\frac{8}{-10}\\\theta =tan^{-1}(\frac{8}{-10})\\\theta =tan^{-1}(\frac{8}{-10})=-38.65^{\circ}[/tex]
Now ,
[tex]\alpha = 180-38.65=141.35^{\circ}[/tex]
So, this vector make an angle of 141° with the positive x axis
