Two people are jogging around a circular track in the same direction one person can go to completely around the track in 21 minutes the second person takes 18th if they both start running in the same direction at the same time how long will it take them to be together at this place if they continue to run
Answer:
n * 21 = m * 18 one runs n laps and one runs m laps to again be together at the same place
7 n = 6 m divide by 3
one runs 7 * 18 = 126 min
the other runs 6 * 21 = 126 min
After 126 min they will be together at the start

A harbor seal dives 35 meters below the ocean's surface. Then it dives down an additional 12 meters Determine the seal's new position relative to the surface of the ocean
The seal's new position relative to the surface of the ocean is 47 meters below.
How to calculate the value?It is important to note that that question has to do with elevation which is the change in position with regards to the sea or ocean level.
In this case, the harbour seal dives 35 metres below the ocean's surface and then it dives down an additional 12 metres
The new position will be;
= -35 - 12
= -47
This implies that it's 47 meters below the ocean surface.

What is Slope?A line's slope is determined by how its y coordinate changes in relation to how its x coordinate changes. y and x are the net changes in the y and x coordinates, respectively. Therefore, it is possible to write the change in y coordinate with respect to the change in x coordinate as,
m = Δy/Δx

9. The sum of two numbers is 130 and their difference is 34. Let x be the first number and y be the second
number. Set up a system of equations and use the elimination method to find the numbers. You must
show your work.
Using the system of equations and use the elimination method the two numbers are 82 and 48.
What is the elimination method?
To create an equation in one variable using the elimination approach, you can either add or subtract the equations. To eliminate a variable, add the equations when the coefficients of one variable are in opposition, and subtract the equations when the coefficients of one variable are equal.
Here, we
let the first number = x
let the second number = y
according to the given conditions:
x + y = 130 ........(1)
x - y = 34 .........(2)
Using the elimination method we add both equations (1) and (2) and we get
2x = 164
x = 164/2 = 82
Now, we substitute the value of x in eq (1) and we get
82 + y = 130
y = 130-82
y = 48
Hence, using the system of equations and use the elimination method the two numbers are 82 and 48.

Lacey inherited some money from her grandfather and put it in a bank account that earns 4%
interest compounded monthly. After 2 years, Lacey had $700.00 in the bank account. How
much interest did she earn?
Round your answer to the nearest cent.
The interest eared from the given amount, rate of interest and time period is $426.883.
Given that, amount = $700, rate of interest = 4% and time period = 2 years.
What is the compound interest?Compound interest is the interest on savings calculated on both the initial principal and the accumulated interest from previous periods.
The formula used to find the compound interest is [tex]Amount=Principal(1+\frac{r}{100})^{nt}[/tex]
Let the money deposited be x.
So, [tex]700=x(1+\frac{4}{100} )^{2\times12}[/tex]
⇒ [tex]700=x(1+0.04)^{24}[/tex]
⇒ [tex]700=x(1.04)^{24}[/tex]
⇒ 700 = 2.563x
⇒ x=700/2.563
⇒ x=$273.117
So, interest = 700-273.117
= $426.883
Therefore, the interest eared from the given amount, rate of interest and time period is $426.883.

What is a parallelogram?
A parallelogram is the name given to a quadrilateral in geometry. In a parallelogram, the opposing sides are parallel and of equal length. The rhombus, rectangle, and square are just a few shapes that are parallelograms.
Having two sets of parallel sides makes a quadrilateral a parallelogram. A parallelogram has opposite sides that are the same length and angles that are the same size. Additionally, the internal angles on the same transverse side are supplementary. 360 degrees are equal to the total of all internal angles.
Two parallel pairs of sides make up a parallelogram, a quadrilateral. Four right angles form a parallelogram called a rectangle.
Rhombus: An equal-length parallelogram with four sides.
The diagonals of a parallelogram bisect each other AC = 2 CE
Substitute AC= 34 into AC = 2CE =34 = 2CE
Calculate 34 = 2 CE=> CE = 17
The diagonals of a parallelogram bisect each other BD = 2DE
Substitute BD= 28 into BD = 2DE => 28 = 2DE
Calculate 28 = 2DE => DE = 14
Opposite sides of parallelogram are congruent AB = CD
Substitute AB = 26 into AB = CD => CD = 26
Perimeter of a triangle PΔCDE = CE + CD + DE
Substitute CE = 17, DE = 14, CD = 26.
PΔCDE = CE + CD + DE
PΔCDE = 17+ 26 + 14

Graph the function rule. Tell whether the graph is continuous or discrete. The height h, in inches, of the juice in a 20-oz bottle depends on the amount of juice j, in ounces, that you drink. This situation is represented by the function rule h=8−0.4j.
Upon graphing of the function rule h = 8 - 0.4j, we see that the graph is continuous.
We are given the function as; h = 8 - 0.4j
Let h represent the height in inches on the y-axis and let j represent the amount of juice in ounces on the x-axis.
We are told that the height of the juice in a 20-oz bottle depends on the amount of juice. This means that j is an independent variable and h is dependent variable.
The function represents the height of juice after drinking j ounces of juice. Therefore as the juice is being drank, the height of the juice in bottle will change continuously. Therefore, the graph of our given function will be continuous because we can drink fractions of an ounce juice.
The equation of a line in slope-intercept form is given as;
y = mx + b
where;
m is Slope of line
b is y-intercept
If we rewrite our function slope-intercept form of equation, we will get;
h = -0.4j + 8
Thus;
Slope = -0.3
y-intercept = 8.

Answer:
Step-by-step explanation:
A ball is kicked with an initial velocity of 15 m/s in the horizontal direction and 18 m/s in the vertical direction. (Assume the ball is kicked from the ground.)
At what speed (in m/s) does the ball hit the ground?
For how long (in s) does the ball remain in the air?
What maximum height (in m) is attained by the ball?
A) The speed (in m/s) at which the ball hits the ground is; 23.43 m/s
B) The time (in s) that it takes the ball to remain in the air is; 3.67 s
C) The maximum height attained by the ball is; 16.51 m
How to solve projectile problems?
A) The motion of the ball on the vertical axis is basically uniformly accelerated motion, with acceleration g = 9.81 m/s² and initial vertical velocity v_y = 18 m/s, so the vertical position of the ball at time t is:
y(t) = v_y*t - ¹/₂gt²
The formula for time when the ball hits the ground is;
t = 2v_y/g
t = (2 * 18)/9.81
t = 3.67 s
Thus, vertical velocity at time t is given by the formula;
v_y(t) = v_y - gt
v_y(t) = 18 - (9.81 * 3.67)
v_y(t) = -18 m/s (which shows it is in the opposite direction because of the negative sign)
Thus, the speed at which the ball hits the ground is the resultant of the vertical and horizontal velocity at time t;
v = √(v_x² + v_yt²)
v = √(15² + 18²)
v = 23.43 m/s
b) From a above, the time that the ball remains in the air is the time it takes to hit the ground which is t = 3.67 s
c) The time to reach maximum height is half the time it takes to reach the ground. Thus;
t = 3.67/2 = 1.835 s
Thus maximum height is given by the formula;
y(t) = v_y*t - ¹/₂gt²
y(1.835) = 18(1.835) - ¹/₂(9.81)(1.835²)
y = 16.51 m

Arithmetic sequences are sequences of the form:
a, a+d, a+2d, a+3d, a+4d, …
a is the first term and d is the common difference
series. The n terms of the arithmetic progression are given by
[tex]a_{n}[/tex] = a + (n - 1)d
The number d is called the common difference
Arithmetic progressions differ by d and any terms [tex]a_{n}[/tex] and [tex]a_{n-1}[/tex]
d = [tex]a_{n}-a_{n-1}[/tex] -
According to the given pattern, in the first figure, number of dots is 1 , in the second figure, number of dots become 5 , similarly in the next the count is 9 and 14
So, the sequence become

We need to find the number of dots after 100 minutes
So, here n = 100
We need to find [tex]a_{100}[/tex]
[tex]a_{100}[/tex] = a + (100 - 1) d = 1 + 99(4) = 1 + 396 = 397
