A boat travels upstream on the Mississippi River for 3.5 hours. The return trip takes only 2.5 hours because the boat travels 2 miles per hour faster downstream due to the current. How far does the boat travel downstream?
The distance that the boat travel is 17.5 miles per hour.
How to calculate the distance?A boat travels upstream on a Mississippi river for 3.5 hours and the return trip takes 2.5 hours
The boat travels 2 miles per hour faster downstream
Let y = the speed that was traveled upsteam.
This will be illustrated as
3.5y = 2.5(y + 2)
3.5y = 2.5y + 5
3.5y - 2.5y = 5
y = 5
Therefore the distance travelled by the boat upstream will be:
= 3.5 × 5
= 17.5 miles per hour

What is basic algebra ?The area of mathematics known as algebra aids in the representation of circumstances or problems as mathematical expressions. To create a meaningful mathematical expression, it takes variables like x, y, and z together with mathematical operations like addition, subtraction, multiplication, and division. Algebra is used in all areas of mathematics, including trigonometry, calculus, and coordinate geometry. 2x + 4 = 8 is a straightforward algebraic expression. In algebra, symbols are used, and operators are used to connect the symbols to one another. It is more than just a mathematical idea; it is a skill that we all utilize on a regular basis without even being aware of it.

insert brackets to make the statement true 10 + 2 x 3^2 - 2 = 84
Inserting brackets to make the statement true 10 + 2 x 3^2 - 2 = 84 will be (10 + 2) × (3² - 2).
How to illustrate the informationIt should be noted that the information simply means that one had to put the bracket in the appropriate places on order to get the value of 84.
This will be illustrated thus:
= 10 + 2 × 3² - 2
= (10 + 2) × (3² - 2)
= 12 × (9 - 2)
= 12 × 7
= 84

Find the median, mode, and range.
For the given discrete data series,
Median = 4'7"
Mode = 4'8"
Range = 1'3"
To begin with, let us arrange the given discrete data series in ascending order as follows:
3'7" 3'11" 4'3" 4'6" 4'7" 4'7" 4'8" 4'8" 4'8" 4'9" 4'10"
To identify the median, locate the data point that stands exact at midpoint of the series. It is the sixth entry from left and hence median = 4'7"
To identify the mode, count and identify which data points occurs highest in frequency. 4'8" is mode as it occurs highest number of times (3 times) in the series.
To calculate the range, we subtract the last entry. Thus Range = 4'10" - 3'7" = 1'3"

[tex]18^{2}[/tex] + [tex]b^{2}[/tex] = [tex]30^{2}[/tex]

[tex]b^{2}[/tex] = 576
[tex]\sqrt{b^{2} }[/tex] = [tex]\sqrt{576}[/tex]
b = 24
Answer:
24 inches
Step-by-step explanation:
Since the size of the screen is measured from the lower corner to the opposite upper corner.
therefore it forms a right angled triangle.
given hypotenuse is 30inch
the height is 18 inches
using the Pythagorean theorem
[tex] {hypotense}^{2} = {width}^{2} + {height}^{2} [/tex]
then
[tex] {30}^{2} = {width}^{2} + {18}^{2} \\ 900 = {width}^{2} +324[/tex]
Subtract 324 from both sides

How will the volume of a cube change if its edge becomes twice as long; 3 times as
long; 10 times as long; n times as long?
Answer:8s^3 , 27s^3 , n^3s^
Step-by-step explanation:
As we know that
Volume of the cube = side × side × side
let us assume that one side is s
side = 2s
Then,
Volume = 2s ×2s×2s
=8s^3
side =3s
Then,
Volume= 3s×3s×3s
=27s^3
side =ns
Then,
Volume= ns×ns×ns
=n^3 s^3

explain
Ths. nth term of the sequence will be 4 - 3n.
The next three terms will be -5, -8 and -12.
How to illustrate the information?It should be noted that a sequence simply represents the numbers that have a common term between them.
In this case, the numbers that are given include 7, 4, 1 and -2.

C. No correlation
D. Weak negative
E. Strong negative
While graph A shows a Strong Negative Correlation (Option E), Graph B shows a No Correlation. (Option C)
What is a strong negative Correlation?
A significant negative correlation, on the other hand, suggests a substantial relationship between the two variables, but that one rises while the other falls. For example, a correlation of -0.97 suggests a high negative connection, whereas a correlation of 0.10 shows a mild positive correlation.
A scatter plot, also known as a scatter graph or scatter chart, employs dots to represent the values of many numerical variables. To demonstrate a weak positive association, the value of Y grows slightly as the value of X increases.

(100 points) While practicing a tightrope walk at a height of 20 feet, a circus performer slips and falls into a safety net 15 feet below. The function h(t) = -16t^2+20, where t represents time measured in seconds, gives the performer's height above the ground (in feet) as he falls. Write and solve an equation to find the elapsed time until the performer lands in the net. Will give brainiest to person who answers the questions correctly.
The equation to find the elapsed time is -16t^2 + 20 + 15 = 0 and the elapsed time is 1.479 seconds
How to determine the equation to find the elapsed time?The given parameters are:
h(t) = -16t^2 + 20
Also, we have:
Safety net = 15 feet below
This means that
h(t) = -15
Substitute h(t) = -15 in h(t) = -16t^2 + 20
So, we have
-16t^2 + 20 = -15
Add 15 to all sides
-16t^2 + 20 + 15 = 0
Using a graphing calculator, we have
t = -1.479 and t = 1.479
Time cannot be negative
So, we have
t = 1.479
Hence, the time is 1.479 seconds
