A boat travels upstream the Missouri River for 3.5 hours. The return trip takes only 2.5 hours because the boat travel 2 miles per hour faster downstream due to the current. How far does the boat travel downstream? PLEASE HELP PLSPLSPLSPLS
The distance traveled by boat upstream would be 5 miles because downstream, the boat moves 2 miles per hour more quickly.
What is the speed?Speed is defined as the ratio of the total distance traveled by a body to the total time taken for the body to reach its destination.
We have been given that the boat takes 3.5 hours to move upstream on the Mississippi River.
And 2.5 hours are used traveling back.
Downstream, the boat moves 2 miles per hour more quickly.
Let the speed of travel upstream would be x
⇒ 3.5x = 2.5(x + 2)
⇒ 3.5x = 2.5x + 5
⇒ 3.5x - 2.5x = 5
⇒ x = 5
So the distance traveled by boat upstream would be
= 3.5 × 5
= 17.5 miles per hour
Therefore, the boat travels 5 miles downstream.

The sum of three lengths of a fence ranges from 31 to 40 inches. two side lengths are 9 and 12 inches. if the length of the third side is x inches, write and solve a compound inequality to show the possible lengths of the third side. 31 ≤ x ≤ 40 22 ≤ x ≤ 28 10 ≤ x ≤ 19 9 ≤ x ≤ 12
If two side lengths of a fence are 9 and 12 inches and the sum of the three lengths ranges from 31 to 40 inches, then the length of the third side, x, can be presented by the compound inequality 10 < x < 19.
Inequality refers to the relationship between two non-equal expressions. It can be denoted by > for greater than, < for less than, >/= for greater than and equal to, and </= for less than and equal to.
Given that the sum of the three lengths of a fence ranges from 31 to 40 inches, the inequality can be written as:
31 < sum < 40
If two side lengths are 9 and 12 inches, and let x be the third length, the inequality becomes:
31 < 9 + 12 + x < 40
31 < 21 + x < 40
Subtracting 21 at all sides,
31 - 21 < 21 + x - 21 < 40 - 21
10 < x < 19
Hence, the compound inequality to show the length of the third side can be written as 10 < x < 19.

9. Marlee is making jewelry for a class craft
show. She began with 115 inches of wire.
She used 25.75 inches for rings. Then her
teacher gave her 30 1/4 inches of wire to
make more jewelry. She then used 38 1/2
inches for the bracelets and 60.2 inches for
necklaces. How much wire does Marlee
have left?
The wire that Marlee had left is 20.8 inches.
How to calculate the fraction?From the information given, it was stated that Marlee is making jewelry for a class craft show and that she began with 115 inches of wire.
Amount used for rings = 25.75 inches..
Amount given to her by the teacher = 30 1/4 inches.
Amount used for bracelets = 38 1/2
inches.
Amount used for necklace = 60.2 inches
It should be noted to know the wire left, we have to subtract the values that were used and then add the value that her teacher gave her from the original value. This will be calculated thus:
This will be:
= 115 - 25.75 + 30.25 - 38.5 - 60.2
= 20.8 inches
Therefore, in conclusion, the wire that Marlee had will be 20.8 inches left.

txt: identify the domain and range of the following relation and determine if the relation is a function. Explain why or why not.
We need to know about relation and function to solve the problem. The domain of the relation is {-4,2,7,10} and the range is {-4}. The relation is a function.
Relation is a subset of Cartesian product or we can say that it is a set of points. It can also be described as a collection of ordered pairs.Function is a relation which follows that each input should have only one output. The domain of a relation or function is the set of values that the relation can accept, the range of a relation is the set of values that can be an output of the function or relation. The x values are the inputs and form the domain whereas the y values give the range. In the given relation the domain of the relation is {-4,2,7,10} and the range of the relation is {-4} since there is only one ouput value. The relation is a function since every input has only one output.
Therefore the domain of the relation is {-4,2,7,10} and the range is {-4} and the relation is function.

Answers to Question 6: m∠1 = 92, m∠2 = 88
The sum of a linear pair's angles is 180°, so we will set up an equation to solve.
(x + 67) + (3x + 13) = 180
4x + 80 = 180
4x = 100
x = 25
-
(x + 67) ➜ (25 + 67) ➜ 92
(3x + 13) ➜ (3(25) + 13) ➜ 88
Answer to Question 7: m∠2 = 56
Vertical angles are congruent, or equal, so we can set up an equation to solve.
(5x + 16) = (4x + 24)
x = 8
-
(5x + 16) ➜ (5(8) + 16) ➜ 56
(4x + 24) ➜ (4(8) + 24) ➜ 56

The two numbers with the value of 9 in the first digit being 10 times the value of 9 in the second digit are 98 and 9.
Given that the value of the digit 9 in the second number is 10 times the value of digit 9 in the first number .
The first number will be 9 and the second number will be 98.
In the second number, the 9 is in the tens position which means that it has the value of 90.
In the first number, the value of 9 is simply 9.
90 is 10 times the value of 9 which means that 9 and 98 satisfy the requirements.

The function f(x) = x² + 4 is defined on the domain [-8, 8]. Which of the following is the correct associated range?
O [4, 68]
O [0, 4]
O [-60, 4]
O (-∞, 4]
O [-60, 68]
0 (-∞, ∞)
========================================================
Explanation:
The parabola has its lowest point when either x = -8 or x = 8
Plug either value into the function
f(x) = -x^2 + 4
f(-8) = -(-8)^2 + 4
f(-8) = -60
You should find that f(8) = -60 as well
This is the lowest output possible. Confirmation of such can be done using a graph. Look for the lowest point and only focus on the interval [tex]-8 \le \text{x} \le 8[/tex]
The highest point is at the vertex (0, 4), so the largest output is y = 4
------------
We have the lowest output y = -60 and the highest output y = 4
The possible set of outputs is the interval [tex]-60 \le \text{y} \le 4[/tex] which turns into the interval notation [-60, 4]

What is the standard deviation and its meaning given this population of customer ages? 45, 76, 30, 22, 51, 40, 63, 66, 41
The standard deviation is 16.54 if the population of customers ages is 45, 76, 30, 22, 51, 40, 63, 66, and 41.
What is the standard deviation?It is defined as the measure of data disbursement, It gives an idea about how much is the data spread out.
[tex]\rm SD = \sqrt{\dfrac{ \sum (x_i-X)^2}{N}[/tex]
SD is the standard deviation
xi is each value from the data set
X is the mean of the data set
N is the number of observations in the data set.
It is given that:
The data set:
45, 76, 30, 22, 51, 40, 63, 66, 41
From the formula:
∑(x(i) - X)² = 2463.55
N = 9
SD = √(2463.55/9)
SD = 16.54
Thus, the standard deviation is 16.54 if the population of customers ages is 45, 76, 30, 22, 51, 40, 63, 66, and 41.
