A boat can travel 140 kilometers on 35
liters of gasoline. How much gasoline will
it need to go 432 kilometers?
Answer: 108 liters of gasoline is needed.
Hope this helps! :)
Given parameters:
Distance = 140km
Volume of gasoline = 35liters
Unknown:
Volume of gasoline needed for 432km = ?
Solution:
Let us first find the rate of gasoline consumption per mile. Using this value, we can then determine the volume of gasoline used for the distance given.
Rate of gasoline consumption by the boat = [tex]\frac{volume of gasoline}{distance}[/tex]
= [tex]\frac{35}{140}[/tex]
= 0.25liters/km
Now, the volume of gasoline needed for 432km;
Volume of gasoline needed = rate of gasoline consumption x distance
= 0.25 x 432
= 108liters of gasoline

Which set of coordinate pairs do NOT represent a linear function?
(−4, −12), (−3, −10), (−2, −8), (−1, −6)
(−4, −17), (−3, −10), (−2, 5), (−1, 2)
(1, −7), (2, −10), (3, −13), (4, −16)
(1, 1), (2, 4), (3, 7), (4, 10)
Answer:
(-4, -17), (-3, -10), (-2,5), (-1,2)
All the coordinates are represent linear function.
What is an expression?Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.
Given that;
The coordinates are,
⇒ (-4, -12), (-3,-10), (-2, -8), (-1,-6)
⇒ (-4, -17), (-3, -10), (-2,5), (-1,2)
⇒ (1, -7), (2, -10), (3, -13), (4, -16)
⇒ (1, 1), (2, 4), (3, 7), (4, 10)
Now,
We know that;
A relation between a set of inputs having exactly one output each is called a linear function.
Clearly, All the coordinate have exactly one output for every input.

[tex]-7\sqrt{3}\pi[/tex]
Add similar elements
:)Hope you enjoy this:)Answer:
A. [tex]-7\sqrt{3}\pi[/tex]
Step-by-step explanation:
To find the simplified form of that expression, we have to combine like terms. To do this, we should remember that:
ab + cb = (a + c)b
[tex]\pi\sqrt{3}-8\pi\sqrt{3}=(\pi-8\pi)\sqrt{3}=((1-8)\pi)\sqrt{3}=-7\pi\sqrt{3}=-7\sqrt{3}\pi[/tex]
So the simplified form would be [tex]-7\sqrt{3}\pi[/tex].

the average rain fall in cuba in the summer is 5.3 inches per month. if cuba gets 6.3 inches in june and 7.1 in july how much rain do they need in august to exceed their average
Answer:
They need more than 2.5 inches.
Step-by-step explanation:
average = 5.3
June: 6.3
July: 7.1
August: x
The average of the amounts for June, July, and August is
(6.3 + 7.1 + x)/3
To exceed the average, the average must be greater than 5.3.
(6.3 + 7.1 + x)/3 > 5.3
Multiply both sides by 3.
6.3 + 7.1 + x > 15.9
x + 13.4 > 15.9
Subtract 13.4 from both sides.
x > 2.5
Answer: They need more than 2.5 inches.

A linear regression has a correlation coefficient of r=0.82
. Would this be a good correlation coefficient? What is the best value you could have for a correlation coefficient? Explain your reasoning completely.
Answer:
not very good
Step-by-step explanation:
the correlation should be almost 1 to be a good representation of the data. 0.82 isn't very close. This would be a pretty "rough" approximation at best. Maybe that's all that's needed but usually something close to 1.. like 0.99 is needed.

(? x 3) - 3 = 15
help pls and i need the steps :/
Answer:
4
Step-by-step explanation:
Lets make [tex]x[/tex] be the ? in the equation.
That becomes ([tex]x[/tex] x 3) - 3 = 15.
First you have to add 3 on both sides. After doing that it gets to ([tex]x[/tex] x 3) = 15 - 3.
Then you simplify it to 3[tex]x[/tex] = 12.
Now you divide 3 on both sides. That gets to [tex]x[/tex] = 4 after doing it.
Hope this helped! If not, please let me know! <3
