The steps involved in using dimensional analysis for unit conversion is highlighted below :
The question is incomplete, however, from the portion given, we can see that the text is based on using dimensional analysis to convert units of measurement.
We relate our given unit to the desired or expected unit :
From the text:
To convert 3 miles into feets :
The given unit = 3 miles
The expected or desired unit = feets
The relationship between Given and desired unit :
1 mile = 5280 feets
(5280 feets / 1 mile )
With the unit we want or desire placed at the bottom
To convert a given number of miles to feets ;
Multiply the given value by the relation defined :
Hence,
3 miles to feets :
3 miles × (5280 feets / 1 mile)
Miles cancels out
3 × 5280 feets = 15,840 feets
Another example :
Convert ; 10 minutes into seconds :
1 minute = 60 seconds
given unit = minute ; desired unit = seconds
Relationship = (60 seconds / 1 unit)
10 minutes × (60 seconds / 1 minute)
Minute cancels out :
10 × 60 seconds = 600 seconds

Step-by-step explanation:
Use a fraction calculator
Given f(x) = x2 − 4x + 3 and g(x) = −x − 6, identify f(g(−2)).
a. 35
b. 99

Zach and Ginny are building model cars. Ginny's car is 2 more than 3 times the length of Zach's car. The sum of the lengths of both cars is 30 inches. Write an equation to determine the lengths of Zach's and Ginny's cars.
3x + 2 = 30
x + 2 + 3x = 30
2x + 3 = 30
x + 2x + 3 = 30
Answer:
x + 2 + 3x = 30
Step-by-step explanation:
Both lengths are unknown, but Ginny's car length is described in terms of Zach's car length, so we choose a variable for Zach's car length.
Let x = Zach's car length.
Zach's car length is x.
"Ginny's car is 2 more than 3 times the length of Zach's car."
Ginny's car length is 2 + 3x.
Add the lengths:
x + 2 + 3x
"The sum of the lengths of both cars is 30 inches."
x + 2 + 3x = 30
Answer: x + 2 + 3x = 30

HOPE THIS HELPS YOU......why do you multply by a power of 10 when writing a repeating decimal as a fraction
The goal is to multiply by a certain number (10, 100, 1000, etc.) so that when the original number is subtracted from the multiple, the repeating element cancels out. 10x = 2 is the result of multiplying by ten.

2 25 divided by 11 10 in fraction
Answer:
[tex] \frac{4}{55} [/tex]
Step-by-step explanation:
[tex] \frac{2}{25} \div \frac{11}{10} [/tex]
[tex] \frac{2}{25} \times \frac{10}{11} [/tex]
[tex] \frac{2}{5} \times \frac{2}{11} = \frac{2 \times 2}{5 \times 11} [/tex]
[tex] \frac{4}{5 \times 11}[/tex]
[tex] = \frac{4}{55} [/tex]
The given information is,
→ (2/25) ÷ (11/10) = ?
Let's find the required solution,
→ (2/25) ÷ (11/10)
→ (2/25) × (10/11)
→ 20/275
→ 4/55 {simplest form}
Hence, 4/55 is the answer.

I’ve been stuck on the same question for days now
Answer:
7
Step-by-step explanation:
You've said that both triangle are equal.
This means, both are in proportion
Let the unknown side be x
4 : 5 : x = 36 : 45 : 63
Divide LHS by 9
4 : 5 : x = 4 : 5 : 7
Since you may see x and 7 are same. So, the missing side is 7.
Answer:
Step-by-step explanation:
[tex]\frac{AB}{PQ} = \frac{BC}{QR}[/tex] #1 Find same sides
So, [tex]\frac{4}{36} =\frac{BC}{63}[/tex] #2 fill it in.
36BC= 252 #3 Cross multiply.
[tex]\frac{36BC}{36}[/tex]= [tex]\frac{252}{36}[/tex] #4 Divide by 36
BC= 7 #5 Here's your answer!
If you want to check, plug the sides in.
[tex]\frac{4}{36} =\frac{5}{45} =\frac{7}{36}[/tex]
[tex]\frac{1}{9} =\frac{1}{9} =\frac{1}{9}[/tex]
The siplified fractions should all equal the same number. If they do, the triangles are similar.

Change the mixed numbers to improper fractions
([tex]\frac{9}{2}[/tex] - [tex]\frac{11}{3}[/tex] ) + [tex]\frac{5}{3}[/tex] ← the LCM of 2 and 3 is 6
= [tex]\frac{9(3)}{2(3)}[/tex] - [tex]\frac{11(2)}{3(2)}[/tex] + [tex]\frac{5(2)}{3(2)}[/tex]
= [tex]\frac{27}{6}[/tex] - [tex]\frac{22}{6}[/tex] + [tex]\frac{10}{6}[/tex]
= [tex]\frac{5}{6}[/tex] + [tex]\frac{10}{6}[/tex]
= [tex]\frac{15}{6}[/tex]

Answer:
Step-by-step explanation:
54 = 6*9
That means there are 3 threes and 1 two
54 = 2*3 * 3 * 3
There are a pair of 3s and a two and a 3 left over.
The two and the three remain under the root sigh.
One of the pair of threes comes out of the root sign.
The other one is thrown away.

8x (+ 1 - 1) = 81 - 1
8x = 80
8x/8 = 80/8
x = 10
