Place the following in order from least to greatest. 8,000,000 mm, 5 km, 7000,000 cm, 6,000 m
Answer: 5km, 6000m, 8,000,000 mm, 7000000 cm
Step-by-step explanation:
Note that:
1km = 1,000,000mm
1m = 1000mm
1cm = 10mm
Therefore,
5 km = 5 × 1,000,000mm = 5,000,000mm
7000,000 cm = 7,000,000 × 10 = 70,000,000mm
6,000 m = 6000 × 1000 = 6,000,000mm
Therefore, from the least to the greatest will be:
5km, 6000m, 8,000,000 mm, 7000000 cm

What is meant when we say "like terms" or that we are "combining like terms, and how does this relate to writing expressions in standard form.
Step-by-step explanation:
We call like terms only when we have some variables parts. For example 3x and 4x are like terms whereas 3x and 4w are not like terms.
The best thing about line terms are they can be combined together that is added, subtracted, multiplied or divided. For instance
3x+4x=7x or 4x-3x=x.
Lets us learn more by taking example containing more than one variable
3x+2y+4x+7−y
=3x+4x+2y−y+7
=(3+4)x+(2−1)y+7
=7x+y+7
So, 3x+2y+4x+7−y in standard form becomes 7x+y+7

P.s if you feel this answer is satisfactory please mark it brainiest. I need it for my rank.
NEED HELP ASAP 15 POINTS
Answer:
mean = 2
median = 2.5
Step-by-step explanation:
There are a total of 20 goals (1*0 + 3*1 + 1*2 + 3*5 = 0 + 3 + 2 + 15 = 20)
There are 10 games, so 20/10 = 2 = mean
Threre are 5 games with goals greater than 2.5 and 5 games with goals below 2.5. So the median is 2.5

Based on historical data, your manager believes that 43% of the company's orders come from first-time customers. A random sample of 243 orders will be used to estimate the proportion of first-time-customers. What is the probability that the sample proportion is between 0.2 and 0.39?
Answer:
Following are the solution to the question:
Step-by-step explanation:
[tex]p = 0.43\\\\n = 243\\\\\sigma =\sqrt{\frac{p(1-p)}{n}}=\sqrt{\frac{0.43 (1 -0.43)}{243}}=0.0013[/tex]
z-score for [tex]\hat{p}=0.2[/tex] will be:
z score for will be:
[tex]z=\frac{\hat{p}-p}{\sigma}=\frac{0.39 - 0.43}{0.0013}=-30.76[/tex]
[tex]P(0.2 <\hat{p}< 0.39) = P(-176.92 < z < -30.76)[/tex] using excel method to calculate the value.

Solid a is a right, rectangular prism, in other words is a box. The length and width are double to form solid b, but the heigth of solid a and solid b are the same. How would each quantity in solid a be changed to find the quantity in solid b
Answer:
The length and width dimensions of solid 'a' are multiplied by 2 while the height remains the same to get the representative quantity in solid, b
Step-by-step explanation:
The given parameters of solid 'a' are;
The shape of solid, a = Right, rectangular prism
Let 'l' represent the length of solid 'a', let 'w' represent the width of solid 'a' and let 'h' represent the height of solid 'a'
We have;
The length of solid, [tex]l_b[/tex] = 2·l
The width of solid, [tex]w_b[/tex] = 2·w
The height of solid, [tex]h_b[/tex] = h
Given that we have;
The length of solid, b = 2 × The length of solid, a
The width of solid, b = 2 × The width of solid, a
The height of solid, b = The height of solid, a
The dimensions of length and width of each quantity in solid 'a' will be multiplied by 2 to find the dimension of a similar quantity in solid 'b'
The change in volume from solid 'a' to solid 'b' is given as follows;
The volume of solid, 'a', Vₐ = l × w × h = l·w·h
The volume of solid, 'b', [tex]V_b[/tex] = 2·l × 2·w ×h = 4·l·w·h
[tex]V_b[/tex] = 4 × Vₐ
Therefore, the volume of each unit volume in solid 'a' is multiplied by 4 to get the volume of the image of the unit volume in solid 'b'
The cross sectional area of solid 'a', Aₐ = l × w
The cross sectional area of solid 'b', [tex]A_b[/tex] = 2·l × 2·w = 4·l·w
[tex]A_b[/tex] = 4 × Aₐ
The cross sectional area of each unit of solid 'a' is multiplied by 4 to get the image of the unit cross sectional area in solid 'b'.
Therefore;
The change in the height and width of of solid 'b' is equal to a change in twice the height and width of solid 'a' at a given height, 'h'
The relationships are;
[tex]l_b[/tex] = 2·l, [tex]w_b[/tex] = 2·w, [tex]h_b[/tex] = h
Jane borrowed $200 from her parents to buy a video game system. She has agreed to pay them back $35 each week. Which equation represents the amount of money Jane still owes her parents, p, after w weeks?
Answer:
p = 200 - 35w
Step-by-step explanation:
Let's represent
Number of weeks = x
Amount of money Jane still owes her parents = p
From the above question, we are told:
Jane borrowed = $200
She agreed to pay = $35 each week. Therefore, the equation that represents the amount of money Jane still owes her parents, p, after w weeks is written as:
p = $200 - $35 × w
p = 200 - 35w

The radius of a circle is 1 inch. What is the area of a sector bounded by a 135° arc?
Answer:
http://www.1728.org/radians.htm
The area of a sector = (central angle /360°) * PI * radius^2
area = (135 / 360) * 3.14159265 * 1 * 1
area = .375 * 3.14159265 * 1
area = 1.17809724 square inches

140
Answer:
Step-by-step explanation:
Sum of angles of a triangle = 180
x + (180 - 105) + (180 -140) = 180
x + 75 + 40 = 180
x = 180 -75 - 40
x = 65
