Jack and Diane are jogging back and forth along a one-mile path. They started out at 9:00 A.M. from opposite ends of the path. They passed each other in 10 minutes when Diane has gone 1/3 mile. What time will they meet at the same end of the path? You have to assume they keep jogging at the same speeds.
Explain:
Answers
If they keep running at the same pace, they will eventually meet at the same end of the course after 30 minutes.
what is speed ?The rate at which distance and time change is what is meant by speed. It has the aspect of temporal and spatial distance. The basic unit of distance with the basic unit of time are combined to form the SI unit of speed. This means that the SI unit of speed is the metre per second.
The way that the issue is described is vague.
I believe what is being said here is that they continue to jog at the same speed.
Half a mile per ten minutes is Diane's speed.
2/3 miles per 10 minutes is Jack's speed.
The numerator and denominator (top and bottom of the ratio) must be multiplied by the factor between 10 minutes and an hour (60 minutes) in order to convert this to a standard miles per hour format.
60/10 = 6.
In order to convert the above speeds to miles per hour, we must multiply both speeds by 6.
Diane: (1/3 divided by 6)/hour equals 2 miles/hour
Jack: (4 miles per hour) = (2/3 x 6) / hour
Diane will complete one length in the time it takes Jack to complete a round trip (back) because he runs twice as fast as she does.
Running a mile at a speed of two miles per hour takes Diane 30 minutes.
Running 2 miles (back and forth) at a speed of 4 miles per hour will take Jack 30 minutes.
So after 30 minutes they will meet again at his starting point.

Answers
The amount that store earns is $120. By writing the equation for the given payment of the computer by Rudo, we get the required value.
How much did the store earn on the sale of a computer?It is given that, Rudo buys a computer for $920. This is 115% of what the store paid for the same computer.
So, consider the amount paid by the store for the same computer as 'x'.
Then, from the given information we can write that,
$920 = 115% of x
⇒ 920 = 0.15x
⇒ x = 920/0.15 = 800
So, the amount paid by the store for the same computer is $800
Thus, the amount earned by the store on the sale is $920 - $800 = $120.

the output voltage for an electric circuit is specified to be 130.asampleof40independentreadings on the voltage for this circuit gave a sample mean 128.6 and standard deviation 2.1.test the hypothesis that the average output voltage is 130against the alternative that it is lessthan 130.useatestwithlevel.05
Answers
Consequently, we deduce that the typical output voltage is under 130.
What is standard deviation ?In statistics, the standard deviation measures how widely distributed or how much a bunch of values can vary. While a big standard deviation shows that values are scattered throughout a wider range, a low standard deviation suggests that values are frequently close to the set's mean.
Here,
A defined output voltage of 130 is offered for an electrical circuit.
The voltage for this circuit was measured 40 times independently, with a sample mean of 128.6 and a standard deviation of 2.1.
Let's say the average output voltage.
Null Hypothesis, [tex]H_{0}[/tex]: = 130 denotes that the average output voltage is 130.
A Different Hypothesis, [tex]H_{A}[/tex] : < 130 ( it indicates that the average output voltage is below 130.)
One-sample t test statistics will be employed in this case because we are unsure about the population standard deviation;
T.S. = ~ [tex]\frac{X^{'}-u }{\frac{s}{\sqrt{n} } }[/tex]
In this case, sample mean output voltage equals 128.6
Sample standard deviation equals 2.1, or s.
n = 40 for the sample of independent readers.
Thus, test statistics equal.
So, test statistics = ~[tex]\frac{128.6-130 }{\frac{2.1}{\sqrt{40} } }[/tex]
= -4.216
Now, for a left-tailed test with a 0.05 level of significance, the t table provides a critical value of -1.685 at 39 degrees of freedom. We have enough data to reject our null hypothesis because it will fall in the rejection region because our test statistics are smaller than the crucial value of t, which is -4.216 -1.685.
Consequently, we deduce that the typical output voltage is under 130.

Answers
The rate at which the diameter decreases is -0.16cm/min
Diameter:
In geometry, diameter refers the straight line that goes from one side to the other side of a circle, passing through the center.
Given,
Here we need to find if a snowball melts so that its surface area decreases at a rate of 1cm^2/min, find the rate at which the diameter decreases when the diameter is 10 cm. Finish solving the problem. Write an equation that relates the quantities.
Here we obtained the equation that relates the surface area S and the diameter D of a sphere given by
=> S = πD²
Now, we have differentiate the equation as,
=> dS/dt = d/dt (πD²)
=> dS/dt = π d/dt (D²)
=> dS/dt = 2πD dD/dt
Now, Solving for dD/dt, which is the unknown for this problem, we have
=> dD/dt = 1/2πD x dS/dt
Now, substituting the given values, the rate of change of the diameter when D=10 cm and dS/dt as (-1) is
=> dD/dt = 1/2 x π x 10 (-1)
=> dD/dt = -1/20π

(e) Area between 17 and 30 is 0.0884.
We have given that a variable is normally distributed with mean 21 and standard deviation 7.
(a) We have to find area to the left of 24.
We will use z-formula
i.e Z = (X - μ) / σ
where X is the row score, μ is mean and σ is standard deviation.
Substituting the values we get,
Z = (24 - 21)/ 7
= 3/7
Z = 0.4285
The p-value for 0.4285 is 0.6683.
Therefore area to the left of 24 is 0.6683.
(b) Now to find area to the left of 17,
Z =(17 - 21)/7
= - 4/7
Z = -0.5714
The p-value for -0.5714 is 0.284.
The area to the left of 17 is 0.284
(c) To find the area of the the right of 19,
Z = (19 - 21)/ 7

(d) The area of the right of 25 is,
Z = (25 - 24)/7
= 1/7
Z = 0.1428
The p-value for 0.128 is 0.8981.
Area right of 25 is 1 - 0.8981 = 0.1019.
(e) To find area between 17 and 30 first we will find area of 17 and 30 individually.
We know area of 17 is 0.284.
Now area of 30,
Z = (30 - 24)/7
= 6/7
Z = 0.8571.
P-value for 0.8571 is 0.1956.

Calculate the initial value for -12x - 10y = -50
Answers
The initial value for the equation, -12x - 10y = -50, is: 5.
How to Determine the Initial Value of a Linear Equation?The initial value of a linear equation is also known as the y-intercept of the equation. Th equation in slope-intercept form can be expressed as y = mx + b, where the initial value of the equation is represented as the value of b, while m is the slope.
Given the linear equation, -12x - 10y = -50, in standard form, to find the initial value, b, we have to rewrite the equation in slope-intercept form:
-12x - 10y = -50
Add 12x to both sides of the equations:
-10y = 12x - 50 [addition property of equality]
Divide both sides by -10
-10y/-10 = 12x/-10 - 50/-10 [division property of equality]
y = -6/5x + 5

Exchange the variables, x for y and y for x
x = 2y / 3 - 17
Isolate the variable y
Adds 17 both sides
x + 17 = 2y / 3
Multiply by 3 both sides
3(x+17) = 2y
Divide by 2 both sides
y = 3(x + 17)/2

Additionally, addition, basic arithmetic, multiplication, and division are one or more of the four arithmetic calculations that simple equations undertake.
The system of equations can be expressed in three different ways: in point-slope form, standard form, and slope-intercept form.
So, the parent function is therefore known to be:
f(x) = (1/7)^x
Observe that the y-intercept results from evaluating this in zero:
f(0) = (1/7)^0 = 1
The graph's y-intercept is located at y = -3.
As a result, the function was translated downward by 4 units, bringing it to a point 4 units below the y-intercept of the parent function.
Thus, the graphed function is as follows:
g(x) = f(x) - 4
g(x) = (1/7)^x - 4
Therefore, the equation is shown in the graph as (C) g(x) = (1/7)^x - 4.

The Oakland Tigers are having team shirts made. One option is to pay Susan's Tees a $34 setup fee and then buy the shirts for $10 each. Another option is to go to City Printing, paying $23 for a setup fee and an additional $11 per shirt. The team parent in charge of the project notices that, with a certain number of shirts, the two options have the same cost. What is the cost? How many shirts is that?
Answers
To find the cost of the shirts, we need to set up a system of equations. Let x be the number of shirts.
Option 1: 34 + 10x = Option 2: 23 + 11x
We can solve this system of equations by subtracting the equations:
34 + 10x - 23 - 11x = 0
11x - 23 = 0
11x = 23
x = 23 / 11
Therefore, the cost is the same when the team orders 23/11 = 2 shirts.

Which of the following is a criteria for construction of triangles A AAA B SAS C ss D None?
Answers
A criteria for construction of triangle include the following: B. SAS.
What is a triangle?In Mathematics, a triangle can be defined as a two-dimensional (2D) geometric shape that comprises three (3) sides, three (3) vertices and three (3) angles only.
Generally speaking, the side, angle, side (SAS) criterion is essential for the construction of any triangle such as the following:
Isosceles triangleObtuse triangleEquilateral triangleScalene triangleRight-angled triangleBased on the side, angle, side (SAS) criterion, a statement which is necessary to prove that two (2) triangles are congruent is that one of its side must be equal to another side because their angles are equal in measure or magnitude.

-40-2(3m+1/2) =7m-2
Answers
Answer:
Step-by-step explanation:
-Start by distributing the 2, -2(3m+1/2).
-Getting -6m-1, your equation should look like -40-6m-1=7m-2
-Combine -40 and -1 to get -41, and then add the -6m to the other side.
-The equation should look like -41=13m-2. Add the 2 to the -41 to get -39.
-Now, we have -39=13m. divide both sides by 13 to get m=-3.
Make X the
subject of m=n+x/p
Answers
Answer:
x = pm - pn
Step-by-step explanation:
m = n + [tex]\frac{x}{p}[/tex] Subtract n from both sides
m - n = n - n + [tex]\frac{x}{p}[/tex]
m-n = [tex]\frac{x}{p}[/tex] Multiply both sides by p
p(m - n) = ([tex]\frac{p}{1}[/tex]) [tex]\frac{x}{p}[/tex] [tex]\frac{p}{1}[/tex] means the same as p
pm - pn = x Distribute the p
x = pm - pn
Triangle PQR is similar to triangle STU. Find the measure of side ST. Figures are not
drawn to scale.
Answers
Answer:
ST = 2.6
Step-by-step explanation:
since the triangles are similar then the ratios of corresponding sides are in proportion, that is
[tex]\frac{ST}{PQ}[/tex] = [tex]\frac{SU}{PR}[/tex] ( substitute values )
[tex]\frac{ST}{18}[/tex] = [tex]\frac{5.2}{36}[/tex] ( cross- multiply )
36 × ST = 18 × 5.2 = 93.6 ( divide both sides by 36 )
ST = 2.6
