Answer:
The dimensional analysis method uses equivalences written in fractional form. Because the numerator and denominator of the fraction are equivalent, the value of the fraction is 1. Multiplying by 1 does not change the quantity, but using an equivalence will change the units (or label). In order for units to cancel they must be in the numerator and the denominator of the fraction
Step-by-step explanation:
Dimensional analysis is a method of problem solving that takes into consideration the identity property of multiplication whereby the product of a number and 1 will always give the same number, that is 1 × n = n whereby the value "n" remains the same after the multiplication
Therefore, a fraction of two equivalent measurements but different units has a value of 1, and multiplying the equivalent fraction with another measurement with the same unit as the denominator of the fraction with a value of 1 changes the unit to that of the unit of the numerator

Answer:
A van can carry 15 students and a bus can carry 21 students
Step-by-step explanation:
System of Equations
There are separate trips to the water park for which vans and buses were rented. Let's call the variables:
x = number of students that a van can carry
y = number of students that a bus can carry
6 vans and 8 buses were filled with 246 students. This leads to the equation:
6x + 8y = 246
Dividing by 2:
4x + 3y = 123 [1]
4 vans and 8 buses were filled with 228 students. Thus, we form the equation:
4x + 8y = 228 [2]
Subtracting [2] minus [1]:
5y = 228 - 123 = 105
Dividing by 5:
y = 105/5 = 21
y = 21
From [1]:
4x + 3*21 = 123
4x + 63 = 123
Subtracting 63:
4x = 60
Dividing by 4:
x = 60/4 = 15
x = 15
A van can carry 15 students and a bus can carry 21 students
What is the solution to this inequality?
6x – 5 > -29
• X > -4
o x > 4
o x < -4
o x < 4
Step-by-step explanation:
the answer is the third one

Jillian is incorrect because the shown graph is not a radical function but a logarithmic function instead. Both radical and logarithmic increase for f(x) when x increases as well.
Note that radical functions do not have any asymptotes, that includes vertical and horizontal.
Part BThe shown graph is a logarithmic function. The name already says it. The logarithmic function is part of logarithmic where the equation is
[tex] log_{a}(m) = n[/tex]
AnswerPart A — Jillian is incorrect. The graph has vertical asymptote at x = 0, and radical functions do not have vertical asymptote.Part B — logarithmicNeed help ASAP!! I’m super bad at rounding!! What’s the number 838 rounded to the hundreds place???

Can Somebody Help Your Girl Here Plz
Answer: They are both correct
Step-by-step explanation:
Jane saying 5 is a factor for every while number that has a 5 in the ones place is correct. For example, in the number 345 or 25, we can see that we have 5 in the ones place and 5 is a common factor for the numbers.
Also, Fred saying 5 is a factor for every while number that has a 0 in the ones place is correct as well. For example, the numbers 10, 20, and 200 all have 0 in their ones place and they have a factor of 5 as well.
Therefore, both of them are correct.

What is the value of [3.6]
A: 3
B: 3.5
C: 3.6
D: 4
Answer: 3
Step-by-step explanation: [ 3.6 ] represents the greatest integer function [ x ]
If x is an integer use that integer
If x is not an integer use the next smaller integer
[ 3.6 ] is not an integer, hence
[ 3.6 ] = 3

In the morning, a farmworker packed 4 pints of strawberries every 4 minutes. In the afternoon, she packed 3 pints of strawberries every 5 minutes. What was the difference between her morning and afternoon packing rates, in pints per hour?
Answer: 24
Step-by-step explanation:
In the morning, a farmworker packed 4 pints of strawberries every 4 minutes. The amount of pints of strawberries packed in an hour would be:
= 4/4 × 60
= 60 pints of strawberries
In the afternoon, she packed 3 pints of strawberries every 5 minutes. The amount of pints of strawberries packed in an hour would be:
= 3/5 × 60
= 36 pints of strawberries
The difference between her morning and afternoon packing rates, in pints per hour would be:
= 60 - 36
= 24
What is the distance between point A and point B?
Answer:
[tex]\sqrt{45}[/tex]
Step-by-step explanation:
Ultimately, you want to find the hypotenuse from the distance of Point A to Point B. From point A to the center of point B, it is nine units up and from there it is three units to the right of Point B. Use the Pythagorean theorem to get your hypotenuse in which you should get 45 as your hypotenuse and when you divide it, it is [tex]\sqrt{45}[/tex].
