Divide distance by time:
3.2 meters / 5 minutes = 0.64
The descent was -0.64 meters per minute
Answer:
.64
Step-by-step explanation:
Whenever you see x per y that means that you're looking at a ratio, which can be expressed as a fraction.
It would look like 3.2/5
The rate of descent may not be consistent, but on average it's reflected by the ratio and so you can just cut 3.2 meters into five equal parts to see, on average, how far the diver descended every minute.
Can anyone help me with this?

Three plus two times a number is seven less than four times a number.
What is that number?
Answer:
5
Step-by-step explanation:
3+2x = 4x-7
3+7=4x-2x
x=5
Answer:
Let the number be x
According to given conditions,
3 + 2x = 4x - 7
3 + 7 = 4x - 2x
10 = 2x
2x = 10
•°• x = 10/2
•°• x = 5
The number is 5.
Megan draws three different diagrams to represent the sample space of flipping a coin and rolling a 6-sided die.
Drag a sample space into the row that fits the description and represents Megan's experiment.
Answer:
The explanation is given below.
Step-by-step explanation:
Given:
Two events take place.
Let event A be flipping a coin
Let event B be rolling a 6-sided die.
Now, a coin has two faces; one is head and the other is tail.
So, the possible outcomes of event A are: {H, T}
H → Head, T → Tail.
Now, a six sided die has six faces each marked with a number. The numbers marked ranges from 1 to 6.
So, the possible outcomes of event B are {1, 2, 3, 4, 5, 6}
Now, each element of set A should match with all the elements of set B.
Now, tabular form should have a row of outcomes of B and a coum of outcomes of event A. Thus,
Outcomes 1 2 3 4 5 6
H H1 H2 H3 H4 H5 H6
T T1 T2 T3 T4 T5 T6
Therefore, the organised list has the following outcomes:
H1 T1
H2 T2
H3 T3
H4 T4
H5 T5
H6 T6
Finally, the correct tree diagram is attached below.

A system of equations is shown below y=3x-7 y=2x+1 what is the solution to the system of equations 8 ,17 -8,17 -8,-17 8,-17
Answer:
(8, 17)
Step-by-step explanation:
y = 3x - 7, y = 2x + 1
Substitute the second equation into the first for y.
2x + 1 = 3x - 7
8 = x
Now use 8 for x in one of the equations and solve for y.
2(8) + 1 = y
y = 17

The base area of a box is 36 square inches. If the volume of the box is 108 cubic inches, what is the height of the box?
The height of a box that has a base area of 36 sq. in. and a volume of 108 cubic inches is: 3 inches.
Recall:
The formula for the volume of a box = base area × height
Given the following dimensions:
base area of box = 36 sq. in.
Volume = 108 cubic inches.
Required: height of the box
Plug in the given values into the formula for the volume of a box
108 = 36 × height
Divide both sides by 36
height = 108/36
height = 3 inches

What are the exact measures of the other two sides of the triangle? Use special right triangles ratios and
show your work
Answer:
30-60-90 is a special right triangle
if the side opposite to the 30 degree angle = x,
then the side opposite to the 90 degree angle = 2x
and the side opposite to the 60 degree angle = x*sqr3

If 21 and 35 are two members of a Pythagorean triple, what is the third member?.
The third member of the Pythagorean triple is 28 and this can be determined by using the Pythagorean theorem.
Given :
21 and 35 are two members of a Pythagorean triple.
The following steps can be used in order to determine the third member of the Pythagorean triple:
Step 1 - The Pythagorean theorem can be used in order to determine the third member of the Pythagorean triple.
[tex]H^2 = P^2+B^2[/tex]
where the hypotenuse is H, the perpendicular is P, and the base is B of the right-angle triangle.
Step 2 - Now, substitute the value of H and P in the above expression in order to determine the value of 'B'.
[tex]35^2 = 21^2+B^2[/tex]
Step 3 - Simplify the above expression.
[tex]B^2= 784[/tex]
[tex]B = 28[/tex]
So, the third member of the Pythagorean triple is 28.

Write a function representing the line that includes the points (2,18) and (5,36).
Answer:
Step-by-step explanation: Find the y-intercept. Write the equation in slope-intercept form. Write an equation of the line that passes through each pair of points. 5. (4, −3), (2, 3)
y=6x+6 is the function representing the line that includes the points (2,18) and (5,36).
What is Slope of Line?The slope of the line is the ratio of the rise to the run, or rise divided by the run. It describes the steepness of line in the coordinate plane.
The slope intercept form of a line is y=mx+b, where m is slope and b is the y intercept.
The slope of line passing through two points (x₁, y₁) and (x₂, y₂) is
m=y₂-y₁/x₂-x₁
The given two points are (2,18) and (5,36).
m=36-18/5-2
=18/3=6
slope of line is 6.
Now we need to find the equation of line passing through (2,18) and (5,36).
We need to find the y intercept.
18=6(2)+c
18=12+c
18-12=c
6=c
So y intercept is 6
The equation of line is y=6x+6
Hence y=6x+6 is the function representing the line that includes the points (2,18) and (5,36).
