The most massive planet in the solar system, Jupiter, has a mass of about 1,898,000,000,000,000,000,000,000,000 kg.
The least massive planet is Mercury, which has a mass of about 330,000,000,000,000,000,000,000 kg.
How many times more massive is Jupiter than Mercury? Answer the questions to find out.
1. Estimate Jupiter's mass using a one-digit whole number times a power of 10. Be sure to include units.
Answer:
Step-by-step explanation:
The number of times that Jupiter is more massive than Mercury is calculated as; 5.75 × 10³ times
How to divide large numbers?
We are given;
Mass of Mercury = 330,000,000,000,000,000,000,000 kg = 3.3 × 10²³ kg
Mass of Jupiter = 1,898,000,000,000,000,000,000,000,000 kg = 1.898 × 10²⁷ kg
Thus, to find how many times more massive is Jupiter than Mercury is;
n = (1.898 × 10²⁷ kg)/(3.3 × 10²³ kg)
n = 5.75 × 10³ times

Cell Phone Plan A charges $25 per month plus $10 per gigabyte of data. Cell Phone Plan B charges $50 per month plus $5 per gigabyte of data. What number of gigabytes of data results in the same cost for one month?
Answer:
[tex]gb = 5.[/tex]
Step-by-step explanation:
[tex]plan \: A. : \\ 25(per \: month) \: + 10(per \: gb) \\plan \: B. : \\ 50(per \: month) \: + 5(per \: gb) \\for \: both \: plan \: to \: be \: equal \: based \: on \: gb : \\ 50 + 5gb = 25 + 10gb \\ 5gb = 25 \\ gb = 5.[/tex]
The number of the Gega bytes for the same cost will be 5 GB.
What is an expression?The mathematical expression combines numerical variables and operations denoted by addition, subtraction, multiplication, and division signs.
Mathematical symbols can be used to represent numbers (constants), variables, operations, functions, brackets, punctuation, and grouping. They can also denote the logical syntax's operation order and other properties.
Given that Cell Phone Plan A charges $25 per month plus $10 per gigabyte of data. Cell Phone Plan B charges $50 per month plus $5 per gigabyte of data.
The two equations can be written as,
Plan A, 10G + 25
Plan B, 5G + 50
Equate two equations for the same cost.
10G + 25 = 5G +50
10G - 5G = 50 - 25
5G = 25
G = 5 gb
Therefore, the number of the Gega bytes for the same cost will be 5 GB.

The length of a rectangle is twice its width. If the perimeter of the rectangle is 48 ft , find its length and width of the rectangle.
Answer:
length=16ft
width= 8 ft
Step-by-step explanation:
Perimeter of rectangle = P = 48ft
Length = 2w
Width = w
Perimeter of rectangle = 2(Length+Width)
48=2(2w+w)
48=2(3w)
48=6w
48/6=6w/6
8=w
w=8ft
Length = 2w = 2(8)=16ft
Width = w = 8ft
Answer:
The length is 16 ft and the width is 8ft
Step-by-step explanation:
48 divided by 4 = 12
one has to be double of the other
12-4=8
12-4=8
12+4=16
12+4=16
16+16+8+8=48

Answer:
[tex]\huge\boxed{l = \frac{p}{2} - 2}[/tex]
Step-by-step explanation:
If we have the equation [tex]p=2(l+w)[/tex] and we want to solve for l, our goal is to isolate l on one side of the equation.
We can do this by reversing the equation - looking at what is stopping l from being alone on one side.
First lets divide both sides by 2:
[tex]p \div 2 = 2(l+w) \div 2\\\frac{p}{2}=l+w[/tex]
Now we can subtract w from both sides.
[tex]\frac{p}{2} - w = l+w-w\\\\\frac{p}{2} - w = l[/tex]

Using the drawing tool, graph the two inequalities on the number line. Take a screenshot of each number line and submit it in the response area below. For this scenario, how does the origin, zero, affect the graphing of the inequalities? What does zero represent? Type your answers in the response area.
The attached number lines represent the inequalities x ≥ 22 and x > -22
The inequalitiesTo answer these questions, we make use of the following inequalities
x ≥ 22 and x > -22
The ≥ inequality sign uses a closed circle, while the > inequality sign uses an open circle.
See attachment for the number line
The impact of the originThe origin of a number line is the point zero on the number line.
It affects the graphing of the inequality because it differentiates between the positive sign and the negative sign.
Also, it is always the midpoint of the number line
What zero represent?The point zero represents the origin of the inequality number line

What is the natural phenomenon that will be explained? or What do we see in nature because of this story? What did the character learn that relates to the nature?
(Ares god of war)
Answer:
“These phenomena, like all others, demand an ultimate exposition of the truth.” This innocuous passage from a 22 March 1930 review in Nature of the book Growth and Trophic Movements of Plants by Jagadis Chandra Bose caught Gregory’s eye: it shared his vision of science as the search for a deep connection with the absolute truth. The review’s 26-year-old author, Lionel John Farnham Brimble (pictured) — Jack to his friends — was duly asked to join the Nature team as an assistant editor in 1931. Like Gregory, Brimble had earlier passed over a career in research to be an educator and communicator of science, and he flourished in the Nature office. In the late 1930s, he actively pushed for schools to teach biology, particularly his speciality of botany, which was previously taught only to girls in Britain.

You work as a lab assistant. Each morning you are responsible for grouping the correct number of test tubes for each experiment that will be conducted that day. Today 40 test tubes will be used for 12 experiments. The first two experiments will require 4 test tubes each. Six of the experiments will require 3 test tubes each, and 2 of the experiments will require 2 test tubes each. Each of the two remaining experiments will use exactly the same number of test tubes.
Which calculation is appropriate to perform first when determining the number of test tubes that will be used for each of the two remaining experiments?
A) 10/2
B) 40 − 30
C) 40 − 12
D) 2(4) + 6(3) + 2(2)
Answer: D
Step-by-step explanation:
In total 40 test tubes are required for 12 experiments.
The first two experiments will require 4 test tubes for each.
Hence, there will be a requirement of = 8 test tubes.
Six experiments require 3 test tubes each.
Hence, these 6 experiments will take 18 test tubes.
Other 2 experiments will take 2 test tubes.
Here, = 4 test tubes will be required.
Till now a total of (8 + 18 + 4) = 30 test tubes have been used.
The remaining number of test tubes is (40 - 30) = 10.
The remaining experiments require test tubes.
The first calculation to perform is 2(4) + 6(3) - 2(2).

Solve the following algebraic equation. Show each step of the process.
1/4 (y+24)=32
Answer:
y=104
Step-by-step explanation:
So you do 4 time the whole process to get 1(y+24)=128
and then you simplify the 1 into (y+24) which gets you y+24.
And now you have y+24=128, you minus 24 on both sides, y+24-24=128-24 which is y=104
Answer:
y = 104
Step-by-step explanation
y+24=32 x 4
y+24=128
y=128-24
y=104
