The mass of an electron is approximately 9.1 x 10^-31 kilograms.
The mass of a proton is approximately 1.7 x 10^-27 kilograms.
Approximately how many times greater is the mass of a proton than the mass of a electron?
A. 5,500
B. 1,900
C. 19,000
D. 55,000
Answer:
1900
Step-by-step explanation:
hello bro how r u i think answer is 1835 but there is no option
The required mass of the proton is 1900 times the mass of the electron. Option B is correct.
What is proportionality?Proportionality is defined as between two or more sets of values, and how these values are related to each other in the sense are they directly proportional or inversely proportional to each other.
here,
The mass of an electron is approximately e = 9.1 x 10⁻³¹ kilograms.
The mass of a proton is approximately p = 1.7 x 10⁻²⁷ kilograms.
Now
p/e = 1.7 x 10⁻²⁷/9.1 x 10⁻³¹
p/e ≈ 1900
p = 1900e
Thus, the required mass of the proton is 1900 times the mass of the electron.

A department store offered a 15% discount off the regular price of a shirt. The amount of the discount is $3. What is the regular price of the shirt?
Answer: $3.53
Step-by-step explanation: 15 percent off can be thought of as 85% of the original value because 100-15 is 85. this means that if x is the value of the original shirt, .85x=3
divide by .85
x=3.5294
which is about $3.53
Answer:
You will pay $12 for a item with original price of $15 when discounted 20%. In this example, if you buy an item at $15 with 20% discount, you will pay 15 - 3 = 12 dollars.

Lin has a scale model of a modern train. The model is created at a scale of 1 to 48. The height of the model train is 102 milliliters. What is the actual height in meters?
Answer:
The actual height is 4.896 m
Step-by-step explanation:
Given
[tex]Ratio= 1 : 48[/tex]
[tex]Scale\ Height = 102mm[/tex]
Required
Determine the actual height in metres
Represent the actual height with x.
So, the ratio of Scale Height to Actual Height as:
[tex]Ratio = 102mm : x[/tex]
To calculate x, both ratios must be equal
[tex]1 :48 = 102mm:x[/tex]
Convert to fraction
[tex]\frac{1}{48} = \frac{102mm}{x}[/tex]
Cross Multiply
[tex]x * 1 = 48 * 102mm[/tex]
[tex]x = 4896mm[/tex]
Convert mm to metres
[tex]x = 4896 * 0.001m[/tex]
[tex]x = 4.896m[/tex]
The actual height is 4.896 m

Jada had some dimes and quarters that had a total value of $12.50. The relationship between the number of dimes, d, and the number of quarters, q, can be expressed by the equation
01.d + 0.25q = 12.5.
1. If Jada has 4 quarters, how many dimes does she have?
2. If Jada has 10 quarters, how many dimes does she have?
3. Is the number of dimes a function of the number of quarters? If yes, write a rule (that starts with d =...) that you can use to determine the output, d, from a given input, q. If no, explain why not.
Answer:
1. 115. If q=4, then the equation tells us that 0.1d+(0.25)⋅4=12.5. Subtracting 1 from both sides gives 0.1d=11.5, so d=115.
2. 100. If q=10, then the equation tells us that 0.1d+(0.25)⋅10=12.5. Subtracting 2.5 from both sides gives 0.1d=10, so d=100.
3. Yes. If you know the number of quarters, then you can determine the number of dimes from the equation. We can even write the equation in a way that shows this: d=125−2.5q. The expression 125−2.5qrepresents the output—it is the rule that determines the output d from a given input q.

The solution is, the scale factor on the map is 557.
What is scale factor?A scale factor is when you enlarge a shape and each side is multiplied by the same number. This number is called the scale factor. Maps use scale factors to represent the distance between two places accurately.
here, we have,
from the given diagram we get,
in the map it is mentioned that,
1 unit = 557 miles.
now, we have to find the scale factor,
i.e. the number, which we have to multiply with the the unit of distance in the map to get the original distance of the two places.
now, we have,
so, it means that the x unit = 557 * x miles.
i.e. the scale factor = 557
Hence, The solution is, the scale factor on the map is 557.

Step-by-step explanation:
The far left area:
30*15=450
The middle area:
-Since there is an eight feet being subtracted it is:
22*15=330
The last side:
-Since there is two 15's at the bottom we must subtract 30 from 45:
15*30*1/2=225
Add the area together:

Answer:
x=2
Step-by-step explanation:
Isolate the variable by dividing each side by factors that don't contain the variable.
Answer:
Step-by-step explanation:
This is a linear equation, and we will need to get the variable by itself.
Let's calculate!
[tex]8+3x=14\\3x=14-8\\3x=6[/tex]
Now we divide both sides by 3. Dividing 3 by 3 is just 1, and we don't need to write the 1, and 6 divided by 3 is two! So your equation will look like this:
[tex]3/3x = 6/3\\x=2\\[/tex]

the speed of light is approximately 3 x 10 to the 8th power meters per second, while the speed of sound is approximately 3.4 meters per second. How many times faster is the speed of light than the speed of sound?
Answer:
The speed of light is 8.8x10⁵ times faster than the speed of sound.
Step-by-step explanation:
We can find how many times faster (R) is the speed of light than the speed of sound as follows:
[tex] R = \frac{c}{v_{s}} [/tex]
Where:
c: is the speed of light = 3x10⁸ m/s
[tex]v_{s}[/tex]: is the speed of sound = 340 m/s (the value given in the statement, 3.4 m/s, is wrong)
[tex]R = \frac{3 \cdot 10^{8} m/s}{340 m/s} = 8.8 \cdot 10^{5}[/tex]
Hence, the speed of light is 8.8x10⁵ times faster than the speed of sound.
