The list shows numbers in order from least to greatest. Negative 15, negative 3 and four-fifths, negative 1.5, blank, 2.3, 5 and two-thirds Which is an integer that can be inserted on the blank line in the list? A. –2 B. Negative 1 and one-third C. 0 D. 1.2
Answer:
The correct option is option C
Step-by-step explanation:
Here we want an integer that can be inserted into the blank.
We have:
-15 , -3 4/5 , -1.5 , blank , 2.3 , 5 2/3
The integer that must be inserted into the blank should have a value between -1.5 and 2.3
What this means is that it should be greater than -1.5 but less than 2.3
Option A is incorrect since -2 itself is less than -1.5
option B is incorrect as it not an integer ( integer are whole numbers)
option C is correct
D. option D is incorrect since it is not an integer

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)
(-1) + (-1) + (-1) + (-1) + ... 500 times =
(a) 500
(b) 1
(c) -1
(d) -500
Answer:
D
Step-by-step explanation:
(-1) + (-1) = -2... so 500 times... it would be -500.

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

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

Answer:
603.44
Step-by-step explanation:
solution,
radius=4 inches
height=12 inches
volume=?
we know,
volume of cylinder = πr^2h
=22/7×(4)^2×12
=22/7×16×12
=603.44 inches^3#
The volume of a cylinder with a radius of 4 inches and a height of 12 inches is 602.88 cubic inches.
What is Three dimensional shape?a three dimensional shape can be defined as a solid figure or an object or shape that has three dimensions—length, width, and height.
We have to find the volume of cylinder whose radius of 4 inches and a height of 12
Radius r = 4 inches
Height h =12 inches
Volume=πr²h
Now plug in the values.
Volume=3.14×4²×12

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
Hulu has two different subscription prices. You can pay $6.88 per month for the year or $60.00 per year. How much less per month is the annual subscription?
Answer:
$22.56
Step-by-step explanation:
$6.88 ⋅ 12 = $82.56
So you would have to pay $82.56 per year if you paid $6.88 per month.
$82.56 - $60.00 = $22.56
You would save $22.56 if you paid $60.00 per year.

how do I solve for 3(2x-1)+2x=4x-11
Answer:
x=-2
Step-by-step explanation:
3(2x-1)+2x=4x-11
6x-3+2x=4x-11
8x-3=4x-11
8x=4x-8
4x=-8
x=-2
The answer to the equation is [tex]x=-2[/tex]
First, you must use distributive property to simplify the equation.
[tex]6x-3+2x=4x-11[/tex]
Then, you must combine like terms.
[tex](6x+2x)-3=4x-11[/tex]
[tex]8x-3=4x=11[/tex]
Next, you must subtract 4x on each side
[tex]4x-3=-11[/tex]
Then, add 3 on both sides
[tex]4x=-8[/tex]
Finally, divide both sides by 4
[tex]\frac{4x}{4} =\frac{-8}{4}[/tex]
[tex]x=-2[/tex]

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

In AJKL, JL is extended through point L to point M, mZLJK = (2x + 2)°,
mZKLM = (82 – 16)°, and m/JKL (3x + 6)". Find mZKLM.
Answer:
<KLM = 48 degrees
Step-by-step explanation:
According to the instructions, we construct the triangle JKL and extend the side JL to point M. The information about the angles is shown in the attached image.
Recall that the addition of all internal angles of a triangle must give 180 degrees.
The angles we need to complete the addition is angle <JLK, which happens to be the supplementary angles to angle <KLM
Therefore <JLK = 180 - (8 x - 16) = 180 - 8 x + 16 = 196 - 8 x
The we can now solve for "x" in the equation of addition of internal angles of a triangle:
(2 x + 2) + (3 x + 6) + (196 - 8 x) = 180
Combining like terms on the left
- 3 x + 204 = 180
subtracting 204 from both sides:
- 3 x = 180 - 204
- 3 x = - 24
divide both sides by "-3" to isolate x
x = - 24 / (-3)
x = 8 degrees
Now that we know "x", we can find the measure of angle <KLM via its formula:
<KLM = 8 x - 16 = 8 (8) - 16 = 48 degrees
