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

on which number line is a point plotted at −15 1/4?
Answer:
C
Step-by-step explanation:
Because it is negative it goes backwards, so it would be on the left side of -15. It doesn't go in the middle because that would be -15 1/2. It does go on the left side of the middle, because that would be -15 3/4. It goes on the right side of the middle because that is -15 1/4.
Answer:
C
Step-by-step explanation:
Since its negative then your going backwards and 1/4 is less than half.

Answer:
C and d
Step-by-step explanation:
Now u can mark the other guy the brainliest
The correct ratio table is c. $0.27 : $0.30, which accurately represents the price per fluid ounce for Clean White and Clean Bright detergents.
To determine the correct ratio table, we need to compare the prices of Clean White and Clean Bright and create a ratio based on the price per fluid ounce.
Clean White:
Price: $8.63
Fluid ounces: 32
Clean Bright:
Price: $7.20
Fluid ounces: 24
To calculate the price per fluid ounce for each detergent, we divide the price by the number of fluid ounces:
Clean White:
Price per fluid ounce = $8.63 / 32 ≈ $0.2697 per fluid ounce
Clean Bright:
Price per fluid ounce = $7.20 / 24 ≈ $0.30 per fluid ounce
Now, let's compare these price per fluid ounce values to the given ratio tables:
a. $0.28 : $0.33
b. $0.26 : $0.31
c. $0.27 : $0.30
d. $0.29 : $0.35
Among the options, the correct ratio table is c. $0.27 : $0.30, which accurately represents the price per fluid ounce for Clean White and Clean Bright detergents.

Can someone please help? Thx ;-;
Answer:
a. 3x+6=30
b. 3(6+x)=30
Step-by-step explanation:
a. As you know, x is the unknown variable. In the first question we know that there are 3 bags that weigh the same amount, however we don't know the amount of pounds that it weighs. So we can mark it with a variable (x). Since there is 3 bags we can multiply 3 by x to get the total weight. There is a 6 pound rice bag inside, and the total weight is 30. Hence, the equation 3x+6=30.
b. In this case, we ae told that each basket contains 3 boxes. with a 6 pound rice bag, and a bag of stuffing. We will represent the weight of the bag of stuffing with an x. The weight of a single box is x+6. Since there is 3 boxes, we can multiply the entire thing by 3.

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.

You roll a 6-sided die.
What is P(4)?
Answer: 0.1666
Step-by-step explanation: To find the probability of an event, you divide the number of favorable events by the number of total events. Since there are 6 total events, and rolling a 4 counts as 1 event, you would divide 1 by 6.
1/6 = 0.1666

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.

1005 ft squared (B)
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:
450+330+225=1005

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.
