You have a canteen that holds 32 fluid ounces and weighs 0.25 pounds when empty. Water weighs 0.065 pound per fluid ounce. You begin a hike with a full canteen of water. Write and simplify an expression for the weight of the canteen and water after you drink x fluid ounces.
The simplification of the expression for the weight of the canteen after drinking is 2.33 lbs
How to write the expressionThe total weight can be gotten as:
weight of empty canteen + ( 32 - x ) of the water x weight of water
This would be represented by
total weight = 0.25 + 0.065 * (32-x)
We have to open up the expression
weight = 0.25 + 2.08 - 0.065x
When the weight is 0 we would have
0.25 + 2.08 - 0.065x0
= 2.33 lbs
Hence the simplification of the expression for the weight of the canteen after drinking is 2.33 lbs

The equation representing when the two planes would be at the same altitude is 9x=486
In terms of mathematics, what is an equation?Equation: A declaration that two expressions with variables or integers are equal. In essence, equations are questions, and attempts to systematically identify the solutions to these questions have been the driving forces behind the creation of mathematics.
From (a) we get that: Altitude of Plane A = 990-18x
Altitude of Plane B = 1476-27x
make 890 - 18x = 1476-27x
-18x+27 x = 1476-890
9x=486
X= 54
so pass 54 seconds will the two plane at the same altitude.

Wendell mailed four packages. Each weighed 1 and 3/8 pounds. What was the total weight of the four packages?
The total weight of 4 packets will be equal to 5 and 1 / 2 pounds.
We are given that:
The total number of packages = 4
Weight of each of the package is given as 1 and 3 / 8 pounds
Weight of 1 package = 1 and 3 / 8 pounds.
Weight of 1 package = 11 / 3 pounds
Now, we need to calculate the total weight of 4 packets.
We will do this my multiplying 4 with the weight of each packet.
So, we get that:
Total weight of 4 packets = 4 × 11 / 8 pounds.
Total weight of 4 packets = 11 / 2 pounds
Total weight of 4 packets = 5 and 1 / 2 pounds.
Therefore, the total weight of 4 packets will be equal to 5 and 1 / 2 pounds.

Which pairs of events are independent?
(a) P(A) = 0.46, P(B) = 0.57, P(A∩B) = 0.25.
P(A) and P(B) are not independent events.
Event A is said to be independent of event B if the probability of occurrence of one of them is not affected by the occurrence of the other.
P(A∩B) = P(A)*P(B) for independent events, which is given 0.25 but P(A∩B) = P(A)*P(B) = 0.46*0.57 = 0.26, data does not match.
P(A) = 0.46 and P(B) = 0.57
For A and B to be independent
P (A and B) = 0.46*0.57 = 0.26 [ does not match with given data that is 0.25]
P (A, not B) =0.46*(1-0.57) = 0.19
P (B, not B) =0.57*(1-0.46) = 0.30
P (not A, not B) = (1-0.46) *(1-0.57) = 0.23
To check if they are independent, sum of all values should be equal to 1
0.57+0.19+0.30+0.23 = 0.98 which is not equal to one.
Therefore P(A) and P(B) are not independent events.

The ordered pair (3, -1) that is a solution is the one which makes the inequality TRUE when the value of the ordered pairs are substitute into the inequality 4x - 3y < 16
What is a solution set to an inequality or an equation?If the equation or inequality contains variable terms, then there might be some values of those variables for which that equation or inequality might be true. Such values are called solution to that equation or inequality. Set of such values is called solution set to the considered equation or inequality.
WE have been given an inequality as 4x - 3y < 16.
Here, we need to get the ordered pair solution to the system of linear equations.
Then Substitute x = 3 and y = -1 into 4x - 3y < 16
4(3) - 3(-1) < 16
12 + 3 < 16
15 < 16
(TRUE)
Therefore, the ordered pair, (3, -1) is the solution because it is the only given ordered pair which makes the inequality true.

Use the linear regression feature on a graphing calculator to find an equation of the line of best fit for the data. Round each value in your equation to the nearest tenth.
The equation of line for the given data is y = 5x -1.
According to the given question.
We have a data of points for a equaton of line.
As we know that the standard equation of line is y = mx + b.
Where, m is the slope of line and b is the y intercept.
Since, the points which are given in the data must satisfy y = mx + b.
Therefore,
Lets take the points (1, 4) and (2, 9) and substitute it in y = mx + b to find the value of m and b.
At x = 1 and y = 4
4 = m + b ..(i)
And at x = 2 and y = 9
9 = 2m + b ..(ii)
From equation i and ii
m = 5
So, b = -5 + 4 = -1
Hence, the equation of line for the given data is y = 5x -1.

The vertical distance of the jump is 4.8 feet.
What was the vertical distance, d, of his jump, rounded to the nearest tenth?We know that the equation that relates the vertical distance of the jump and the time is:
t = √d/2
In this case, we know that the time is t = 1.09 seconds, replacing that in the equation we get:
1.09 = √d/2
Now we can solve that equation for d.
1.09*2 = √d
Now we apply an exponent of 2 in both sides to remove the square root:

Step-by-step explanation:
Given function:
[tex]f(x)=x^3+12x^2-27x+11[/tex]
Differentiate the function:
[tex]\implies f'(x)=3 \cdot x^{3-1}+2 \cdot 12x^{2-1}-27x^{1-1}+0[/tex]
[tex]\implies f'(x)=3x^2+24x-27[/tex]
Find the critical points of the function by setting the derivative to zero and solving for x:
[tex]\implies f'(x)=0[/tex]
[tex]\implies 3x^2+24x-27=0[/tex]
[tex]\implies 3(x^2+8x-9)=0[/tex]
[tex]\implies x^2+8x-9=0[/tex]
[tex]\implies x^2+9x-x-9=0[/tex]
[tex]\implies x(x+9)-1(x+9)=0[/tex]
[tex]\implies (x-1)(x+9)=0[/tex]
[tex]\implies x-1=0 \implies x=1[/tex]
[tex]\implies x+9=0 \implies x=-9[/tex]
Therefore, the critical points are x = 1 and x = -9.
Evaluate the function at the endpoints of each interval as well as the critical points if the critical points fall within the given interval. The largest and smallest values of the function are the absolute extrema.
Part (a)
Given interval = [-10, 0].
One of the critical points is included in the interval.
Evaluate the function at the endpoints and critical point:
[tex]f(-10)=(-10)^3+12(-10)^2-27(-10)+11=481[/tex]
[tex]f(0)=(0)^3+12(0)^2-27(0)+11=11[/tex]
[tex]f(-9)=(-9)^3+12(-9)^2-27(-9)+11=497[/tex]
Therefore:
The absolute maximum of f(x) is 497 which occurs at x = -9.The absolute minimum of f(x) is 11 which occurs at x = 0.Part (b)
Given interval = [-7, 2].
One of the critical points is included in the interval.
Evaluate the function at the endpoints and critical point:
[tex]f(-7)=(-7)^3+12(-7)^2-27(-7)+11=445[/tex]
[tex]f(2)=(2)^3+12(2)^2-27(2)+11=13[/tex]
[tex]f(1)=(1)^3+12(1)^2-27(1)+11=-3[/tex]
Therefore:
The absolute maximum of f(x) is 445 which occurs at x = -7.The absolute minimum of f(x) is -3 which occurs at x = 1.Part (c)
Given interval = [-10, 2].
Both of the critical points are included in the interval.
Evaluate the function at the endpoints and critical points:
[tex]f(-10)=(-10)^3+12(-10)^2-27(-10)+11=481[/tex]
[tex]f(2)=(2)^3+12(2)^2-27(2)+11=13[/tex]
[tex]f(-9)=(-9)^3+12(-9)^2-27(-9)+11=497[/tex]
[tex]f(1)=(1)^3+12(1)^2-27(1)+11=-3[/tex]
Therefore:

The junior varsity football
team scored 23 points in last Saturday’s
game. They scored a combination of 7-
point touchdowns and 3-point field goals.
How many touchdowns and how many
field goals did they score?
Answer:
2 touchdowns, 3 field goals
Step-by-step explanation:
The number of touchdowns cannot be more than 3, so it is relatively easy to find the solution by trial and error.
23 is not divisible by 3, so 0 touchdowns is not a solution
23 -7 = 16 is not divisible by 3, so 1 touchdown is not a solution
23 -14 = 9 is divisible by 3, so 2 touchdowns and 3 field goals is a solution
21 -21 = 2 is not divisible by 3, so there is only one solution.
Answer:
1 touchdown and 3 field goals

You have to start with the values of kilograms and grams. So, here they are:
1 Kilogram = 1000 Grams
(For the record, the root kilo means 1000 in math.)
3/4 should be converted to decimals, so 0.75 is our number now.

How many solutions does this equation have? 3x + 1 = 3( x - 1) + 4
Answer:
infinite number
Step-by-step explanation:

3x + 1 = 3x - 3 + 4
3x + 1 = 3x + 1
3x = 3x
x = x
x = x is true for every value of x, so the equation has an infinite number of solutions.

The ratio of Trout to Goldfish to Perch in the pond by using ratio and proportion theorem in its simplest form is 5:2:13
As per the question statement, we are supposed to find out the ratio of Trout to Goldfish to Perch in the given pond in its simplest form.
It is given that 25% of the fish in a pond are Trout, 10% are Goldfish and the rest 65% are Perch in the given pond.
Let's suppose there are 100 fishes in the pond so
Number of Trout = 25% of 100 = 25
Number of Goldfish = 10% of 100 = 10
Number of Perch = 65% of 100 = 65
Using ratio and proportion theorem,
Trout : Goldfish : Perch = 25:10:65
Trout : Goldfish : Perch = 5 : 2 : 13
