Answer:
14b.) RS = 60; ST = 36; RT = 96
Step-by-step explanation:
Since you have correctly solved for y = 7, all you need to do for b is to plug in y.
RS = 8(7) + 4 = 60
ST = 4(7) + 8 = 46
(You can add RS and ST or plug in for y for RT)
RT = 15(7) - 9 = 96

Sally has a bunch of pennies in her piggy bank. She gives 1/3 of her pennies to her older brother. Then, she gives 2/5 of her remaining pennies to her younger sister. After all this, Sally has 24 pennies remaining. How many pennies did Sally start with?
Answers
She started with 60 pennies
Ratios and propotionsLet the number of a bunch of pennies she has to be "x"
If she gives 1/3 of her pennies to her older brother, she will have 2/3 x remaining
If she gives 2/5 of her remaining pennies to her younger sister, she will have 2/3x- (2/5 of 2/3x) = x remainijg
If Sally has 24 pennies remaining, then;
2/3x - 4/15x = 24
10x-4x/15 = 24
6x/15 = 24
6x = 15 * 24
x = 60
This means that she started with 60 pennies

Solve the system of linear equations by substitution
2x+3y=0
8x +9y =18
Answers
Answer:
Step-by-step explanation:
Step 1:
Isolate x (1st Equation)
2x + 3y = 0
- 3y = -3y
2x = -3y
Step 2:
Divide both sides by 2
x = -3y/2
Step 3:
Replace the x from 8x with -3y/2 and Solve the equation
8(-3y/2) + 9y = 18
-12y + 9y = 18
-3y = 18
y = -6
Step 4:
Go back to the 1st equation and replace the y from 3y with -6. You are now solving for x. Solve the equation.
2x + 3(-6) = 0
2x - 18 = 0
+ 18 = +18
2x = 18
x = 9
Step 5:
Write your final answer.
(x, y) = (9, -6)

Answers
Answer: 60% decrease
Work Shown:
Difference = Large - Small = 1.25 - 0.50 = 0.75
Percent decrease = (difference/original)*100%
Percent decrease = (0.75/1.25)*100%
Percent decrease = (0.60)*100%

Particle P moves along the y-axis so that its position at time t is given by y(t)=4t−23 for all times t. A second particle, particle Q, moves along the x-axis so that its position at time t is given by x(t)=sin(πt)2−t for all times t≠2.
As time t approaches 2, what is the limit of the position of particle Q ? Show the work that leads to your answer.
Show that the velocity of particle Q is given by vQ(t)=2πcos(πt)−πtcos(πt)+sin(πt)(2−t)2 for all times t≠2.
Find the rate of change of the distance between particle P and particle Q at time t=12. Show the work that leads to your answer.
Answers
a) The limit of the position of particle [tex]Q[/tex] when time approaches 2 is [tex]-\pi[/tex].
b) The velocity of particle [tex]Q[/tex] is [tex]v_{Q}(t) = \frac{2\pi\cdot \cos \pi t-\pi\cdot t \cdot \cos \pi t -\sin \pi t}{(2-t)^{2}}[/tex] for all [tex]t \ne 2[/tex].
c) The rate of change of the distance between particle [tex]P[/tex] and particle [tex]Q[/tex] at time [tex]t = \frac{1}{2}[/tex] is [tex]\frac{4\sqrt{82}}{9}[/tex].
How to apply limits and derivatives to the study of particle motiona) To determine the limit for [tex]t = 2[/tex], we need to apply the following two algebraic substitutions:
[tex]u = \pi t[/tex] (1)
[tex]k = 2\pi - u[/tex] (2)
Then, the limit is written as follows:
[tex]x(t) = \lim_{t \to 2} \frac{\sin \pi t}{2-t}[/tex]
[tex]x(t) = \lim_{t \to 2} \frac{\pi\cdot \sin \pi t}{2\pi - \pi t}[/tex]
[tex]x(u) = \lim_{u \to 2\pi} \frac{\pi\cdot \sin u}{2\pi - u}[/tex]
[tex]x(k) = \lim_{k \to 0} \frac{\pi\cdot \sin (2\pi-k)}{k}[/tex]
[tex]x(k) = -\pi\cdot \lim_{k \to 0} \frac{\sin k}{k}[/tex]
[tex]x(k) = -\pi[/tex]
The limit of the position of particle [tex]Q[/tex] when time approaches 2 is [tex]-\pi[/tex]. [tex]\blacksquare[/tex]
b) The function velocity of particle [tex]Q[/tex] is determined by the derivative formula for the division between two functions, that is:
[tex]v_{Q}(t) = \frac{f'(t)\cdot g(t)-f(t)\cdot g'(t)}{g(t)^{2}}[/tex] (3)
Where:
[tex]f(t)[/tex] - Function numerator.[tex]g(t)[/tex] - Function denominator.[tex]f'(t)[/tex] - First derivative of the function numerator.[tex]g'(x)[/tex] - First derivative of the function denominator.If we know that [tex]f(t) = \sin \pi t[/tex], [tex]g(t) = 2 - t[/tex], [tex]f'(t) = \pi \cdot \cos \pi t[/tex] and [tex]g'(x) = -1[/tex], then the function velocity of the particle is:
[tex]v_{Q}(t) = \frac{\pi \cdot \cos \pi t \cdot (2-t)-\sin \pi t}{(2-t)^{2}}[/tex]
[tex]v_{Q}(t) = \frac{2\pi\cdot \cos \pi t-\pi\cdot t \cdot \cos \pi t -\sin \pi t}{(2-t)^{2}}[/tex]
The velocity of particle [tex]Q[/tex] is [tex]v_{Q}(t) = \frac{2\pi\cdot \cos \pi t-\pi\cdot t \cdot \cos \pi t -\sin \pi t}{(2-t)^{2}}[/tex] for all [tex]t \ne 2[/tex]. [tex]\blacksquare[/tex]
c) The vector rate of change of the distance between particle P and particle Q ([tex]\dot r_{Q/P} (t)[/tex]) is equal to the vectorial difference between respective vectors velocity:
[tex]\dot r_{Q/P}(t) = \vec v_{Q}(t) - \vec v_{P}(t)[/tex] (4)
Where [tex]\vec v_{P}(t)[/tex] is the vector velocity of particle P.
If we know that [tex]\vec v_{P}(t) = (0, 4)[/tex], [tex]\vec v_{Q}(t) = \left(\frac{2\pi\cdot \cos \pi t - \pi\cdot t \cdot \cos \pi t + \sin \pi t}{(2-t)^{2}}, 0 \right)[/tex] and [tex]t = \frac{1}{2}[/tex], then the vector rate of change of the distance between the two particles:
[tex]\dot r_{P/Q}(t) = \left(\frac{2\pi \cdot \cos \pi t - \pi\cdot t \cdot \cos \pi t + \sin \pi t}{(2-t)^{2}}, -4 \right)[/tex]
[tex]\dot r_{Q/P}\left(\frac{1}{2} \right) = \left(\frac{2\pi\cdot \cos \frac{\pi}{2}-\frac{\pi}{2}\cdot \cos \frac{\pi}{2} +\sin \frac{\pi}{2}}{\frac{3}{2} ^{2}}, -4 \right)[/tex]
[tex]\dot r_{Q/P} \left(\frac{1}{2} \right) = \left(\frac{4}{9}, -4 \right)[/tex]
The magnitude of the vector rate of change is determined by Pythagorean theorem:
[tex]|\dot r_{Q/P}| = \sqrt{\left(\frac{4}{9} \right)^{2}+(-4)^{2}}[/tex]
[tex]|\dot r_{Q/P}| = \frac{4\sqrt{82}}{9}[/tex]
The rate of change of the distance between particle [tex]P[/tex] and particle [tex]Q[/tex] at time [tex]t = \frac{1}{2}[/tex] is [tex]\frac{4\sqrt{82}}{9}[/tex]. [tex]\blacksquare[/tex]
Remark
The statement is incomplete and poorly formatted. Correct form is shown below:
Particle [tex]P[/tex] moves along the y-axis so that its position at time [tex]t[/tex] is given by [tex]y(t) = 4\cdot t - 23[/tex] for all times [tex]t[/tex]. A second particle, [tex]Q[/tex], moves along the x-axis so that its position at time [tex]t[/tex] is given by [tex]x(t) = \frac{\sin \pi t}{2-t}[/tex] for all times [tex]t \ne 2[/tex].

20men working 8hours a day took 18days to complete a work . How long will 24 men working 5 hours a day take to complete the some work
Answers
Step-by-step explanation:
20 men work 8 hours a day for 18 days.
that are
20×8×18 = 2880 work hours to complete that work.
if 24 men work 5 hours a day, that are
24×5 = 120 work hours per day.
we still need to do the total 2880 work hours.
so, they will need
2880 / 120 = 24 days to complete the work.

Two triangles are said to be similar if the ratio of their corresponding sides are in the same proportion. Also all the corresponding angles are congruent.
