Answer:
1. 0.8165 ; 2. 27.52 ; 3 = 3.8352 ; 4. 812.128 ; 5. 11.8513
Step-by-step explanation:
1. 3 - 2.1835 = 0.8165
2. 38.35 - (3.9 + 6.93) = 27.52
3. 8 - 4.1648 = 3.8352
4. 604 + 406.064 = 1010.064
604 - 406.064 = 197.936
1010.064 - 197.936 = 812.128
5. 18.35 - 6.4987 = 11.8513

The percentage increase in average miles flown per passenger from 1966 to 1976 is 16.9%.
What is an equation?An equation is an expression that shows the relationship between two or more numbers and variables.
In 1966, the average miles flown per passenger was 711 while in 1976, the average miles flown per passenger was 831. Hence:
Percentage increase = [(831 - 711) / 711] * 100% = 16.9%
The percentage increase in average miles flown per passenger from 1966 to 1976 is 16.9%.

I need help asap The average length of a female dolphin is about 181 inches (in).
What is this length in feet (ft) and inches (in)?
The length is ft in.
Answer:
the length of the female dolphin would be 9 ft 3 in
Answer:
15 ft and 6 inches
Step-by-step explanation:
Every foot is 12 inches, and 12 times 15 gets you the closest to 181 without going over 181. 12 times 15 is 180 so all you need is one inch to get to 181.

Answer:
1350 cm^2
A=6a^2= 6 x 15^2 = 1350^2
Answer:
B. 1350 cm^2
Step-by-step explanation:
Hello!
To start, let's understand what surface area is. The surface area is all the space on the outside of the shape.
In this case, we see that the entirety of the outside of the shape is made up of 6 different faces.
We know that this is a cube, so all the measurements of length and width are the same. We are given 15 for one of those, so we know that length and width are all 15.
Because we already determined that the surface area is all the face areas added up, we can now follow that pathway.
We know that there are 6 faces that are equal in the area (due to it being a cube). We also know that the width is the same as the length. That means the area of one face in the cube would be 225 cm^2. Since there are 6 of those faces, we multiply that by 6. 22*6 = 1350 cm^2
That's your answer.
Let me know if you have any questions.

Solving steps:
Answer:
60 : 72 = 5 : 6
Solution:
Try to reduce the ratio further with the greatest common factor (GCF).
The GCF of 60 and 72 is 12
Divide both terms by the GCF, 12:
60 ÷ 12 = 5
72 ÷ 12 = 6
Try to reduce the ratio further with the greatest common factor (GCF).
The GCF of 120 and 144 is 24
Divide both terms by the GCF, 24:
120 ÷ 24 = 5
144 ÷ 24 = 6
The ratio 120 : 144 can be reduced to lowest terms by dividing both terms by the GCF = 24 :
120 : 144 = 5 : 6
Therefore:
120 : 144 = 5 : 6
A) The ratio 60 : 72 can be reduced to lowest terms by dividing both terms by the GCF = 12 :
60 : 72 = 5 : 6
Therefore:
60 : 72 = 5 : 6
Answer:
30 : 36 = 5 : 6
b) Solution:
Try to reduce the ratio further with the greatest common factor (GCF).
The GCF of 30 and 36 is 6
Divide both terms by the GCF, 6:
30 ÷ 6 = 5
36 ÷ 6 = 6
The ratio 30 : 36 can be reduced to lowest terms by dividing both terms by the GCF = 6 :
30 : 36 = 5 : 6
Therefore:
30 : 36 = 5 : 6
Answer:
6 : 7 = 6 : 7
c) Solution:
Try to reduce the ratio further with the greatest common factor (GCF).
The GCF of 6 and 7 is 1
Divide both terms by the GCF, 1:
6 ÷ 1 = 6
7 ÷ 1 = 7
The ratio 6 : 7 cannot be reduced further by dividing both terms by the GCF = 1 :
This ratio is already in lowest terms.
Therefore:
6 : 7 = 6 : 7
Answer:
15 : 18 = 5 : 6
d) Solution:
Try to reduce the ratio further with the greatest common factor (GCF).
The GCF of 15 and 18 is 3
Divide both terms by the GCF, 3:
15 ÷ 3 = 5
18 ÷ 3 = 6
The ratio 15 : 18 can be reduced to lowest terms by dividing both terms by the GCF = 3 :
15 : 18 = 5 : 6
Therefore:
15 : 18 = 5 : 6
Answer:
5 : 6 = 5 : 6
e) Solution:
Try to reduce the ratio further with the greatest common factor (GCF).
The GCF of 5 and 6 is 1
Divide both terms by the GCF, 1:
5 ÷ 1 = 5
6 ÷ 1 = 6
The ratio 5 : 6 cannot be reduced further by dividing both terms by the GCF = 1 :
This ratio is already in lowest terms.
Therefore:
5 : 6 = 5 : 6
Find the surface area of this net.
Answer:
231cm²Step-by-step explanation:
First, let's find the surface area of both the triangles
5x3=15
So, the surface area of the triangles is 15 sq.cm
Now, let's find the surface area of the base (large rectangle in the middle)
12x8=?
10x8=80
2x8=16
80+16=96
12x8=96
So, the surface area of the base, is 96sq.cm
Now, let's find the surface area of both of the side rectangles
12x5=60
60x2=120
So, the surface area of the two side rectangles is 120sq.cm
Now, let's find the total surface area by adding all of our answers.
120+96=216
216+15=231
So hence, the surface area of this net is 231cm²

Find the inverse function of f(x) = x^3/2
Answer:
The answer is f^-1(x)=0^3[tex]\sqrt{x}[/tex]+2
Step-by-step explanation: Now we just change y back to f(x) and add a 0−1 to write it in inverse notation We begin with f(x)= x 3−2 . To find the inverse of any equation, just switch x and y No, before we do that, I'm going to change the equation. I'm going to rename f(x) to y , just so that I don't have to deal with the parentheses or anything. Now, all I have to do is change what f (x) is called, not it's actual value. Anyways, we have y = x 3 − 2 Now we switch x and y and then solve for y Now we've got x = y 3−2 If we add 2 on both sides we have x + 2 = y 3 Now we just need to get y as simple as possible, which we'll do by cube rooting both sides of the equation. That leaves us with y=0 3√x+2 Now we just change y back to f(x) and add a 0−1 to write it in inverse notation
