1.Interest rate=7%p.a.Find the interest of Rs 200 for years.
2.Interest rate=11%p.a.Find the interest of Rs 2000 for years.
Step-by-step explanation:
Question does not specify how many year and is in plural form considering the level of question I will consider it is some typo error and is just 1 year
Step 1
Finding Intrest for Rs200
We have
Principal(P) = Rs 200
Rate (R) = 7%pa
Time (T) = 1year
Intrest(I) =?
We have ,
I =PTR/100
=200*7/100
=Rs 14
Step 2
Finding intrest for Rs2000
Given
Principal(P)=Rs2000
Rate(R) =11%
Time(T) =1 year
Intrest(I) =?
We know,
I =PTR/100
=2000*11/100
= 20*11
=Rs 220

Two buses leave towns 304 miles apart at the same time and travel toward each other. One bus travels 14 mih slower than the other. If they meet in 2 hours, what is the rate of each bus?
Answer:
The faster bus moves at 83mi/h and the slower one moves at 69mi/h.
Step-by-step explanation:
Let's define:
R₁ = rate of bus 1, this is the faster one.
R₂ = rate of bus 2, this is the slower one.
We know that one bus travels 14mi/h slower, then:
R₂ = R₁ - 14mi/h.
Now we know that:
Distance = Speed*Time.
If we add the distances that both busses travel in 2 hours, it should be equal to the initial distance between the buses, then:
R₁*2h + R₂*2h = 304 mi
Then we have the two equations:
R₂ = R₁ - 14mi/h
R₁*2h + R₂*2h = 304 mi
The first step is to replace the first equation in the second one, to get:
R₁*2h + (R₁ - 14mi/h)*2h = 304 mi
And now we can solve this for R₁.
R₁*2h + R₁*2h - 14mi/h*2h = 304 mi
R₁*4h - 28mi = 304mi
R₁*4h = 304mi + 28mi = 332mi
R₁ = 332mi/4h = 83mi/h
The faster bus moves at 83mi/h
And we know that the slower one moves at 14mi/h slower than this, then:
R₂ = R₁ - 14mi/h = 83mi/h - 14mi/h = 69 mi/h

Given r(x) = x2 - 4x2 + 4x – 6, find the value
of r(2). What does your answer tell you about x-2 as a
factor of r(x)? Explain.
Answer:
We are given r(x)Additionally we are given that x=2 Hence: 4-16+8-6=10Use substitution to determine which system is represented by the graph.
Answer:
2x + 4y = 28
-2y = x + 28
Step-by-step explanation:
Looking at the graph, we can see that the lines do not intersect. Therefore, they do not have a shared solution. We need to find the system of equations that does not have a solution.
1) Let's try to solve the third system given (counting from the top). To solve with the substitution method, we need to isolate one variable in one of the equations. I chose to isolate y in -2y = x + 28:
[tex]-2y = x + 28\\y = \frac{-1}{2}x -14[/tex]
2) Now that we've isolated the y in that equation, substitute what y equals in that equation for the y in the other equation. So, substitute [tex]\frac{-1}{2}x-14[/tex] for y in 2x + 4y = 28 and simplify:
[tex]2x + 4(\frac{-1}{2}x - 14) = 28\\2x - 2x- 64 = 28\\-64 = 28[/tex]
In a normal situation, the x's would not cancel out, and we would be able to isolate x to get the x-value of the solution. However, in this case, they have, and we ended up with a false statement, as -64 does not equal 28. Whenever this happens, it means the system does not have a solution. Therefore, the third option would represent the system in the graph.
The given graph shows the simultaneous relationship of equations 2x + 4y = 28 and -2y = x + 28. Option C is correct.
What are simultaneous linear equations?Simultaneous linear equations are two- or three-variable linear equations that can be solved together to arrive at a common solution.
Here,
From the graph, the two lines represents the simultaneous relationship,
Where,
The slope of the both lines is,
m = -1/2
And y-intercept of both lines is,
C₁ = 7 and C₂ = - 14
Now,
equations of the lines are,
y = -x/2 + 7 and y = -x/2 - 14
x + 2y = 14 and x + 2y = -28
or
2x + 4y = 28 - - - - - -(1) and -2y = x + 28 - - - - - - -(2)
Now,
From equation 2 substitute y in equation 1
2x + 4[-x - 28]/2= 28
2x - 2x - 56 = 28
-56 = 28
So the lines are parallel and has no solution.
Thus, the given graph shows the simultaneous relationship of equations 2x + 4y = 28 and -2y = x + 28. Option C is correct.

Write the equation of the function of a parabola with vertex at (–1,–2) and a point (1,–6) that lies on the curve.
Question 9 options:
f(x) = −(x − 1)2 − 2
f(x) = −(x + 1)2 − 2
f(x) = (x + 1)2 – 2
f(x) = (x − 1)2 − 2
Answer:
The second answer is the correct one, f(x) = -(x + 1)² - 2
Step-by-step explanation:
We know that the answer must either be the second or third, because those two have (x + 1) squared, which means that the vertex must have an x co-ordinate of -1.
We also know that the third one can't be correct, as the y-coordinate of -6 requires a negative coefficient of the x^2. Without that the parabola would be moving upward from its vertex of (-1, -2).
With those we can eliminate all answers but the second one

C. [tex]-2\frac{3}{8}[/tex] < -8/6 < -0.85 < 0.8 < 4/3 < 140% in ascending order.
What is ascending and descending order ?In ascending order we write numbers from smaller to greater and in descending order we write numbers from greater to smaller.
According to the given question we have list of fractions decimals and percentages and we have to write them in ascending order.
given [tex]-2\frac{2}{8}[/tex], - 0.85, 4/3, 140%, -8/6, 0.8.
Now let convert all these into one form we choose to convert them in percentage.
[tex]-2\frac{3}{8}[/tex] is -19/8 = -2.375 = -237.5 %.
-0.85 = - 85%.
4/3 = 133%.
140% = 140%
-8/6 = -133%
0.8 = 80 %.
∴ [tex]-2\frac{3}{8}[/tex] < -8/6 < -0.85 < 0.8 < 4/3 < 140%.

Answer:
12.8% decrease
Step-by-step explanation:
if you find the unit rate for the sale, which would be 125 cents divided by 3 cans, equals around 43.6 cents per can. 43.6 cents is an x% decrease of 50 cents, and to find x easily i multiplied by 2. 43.6 x 2=87.2, and 50 x 2 = 100. that means that the sale price is 87.2 % of the original price, which is a 12.8% decrease.

A rectangle has a perimeter of 50 centimeters. If the width of the rectangle is 10 centimeters, what is its length?
Answer:
15 cm
Step-by-step explanation:
The perimeter of a rectangle is 2(L + W), where L is length of the rectangle and W is the width.
If we plug in 10 for W, we get this:
2L + 2(10) = 50 <-- the perimeter
2L + 20 = 50
2L = 30
L = 15

Given:
A line segment AB on a coordinate plane.
The rule of translation is
[tex]f(x,y)\to (x-6,y-3)[/tex]
To find:
The coordinates of A' and B'.
Solution:
From the given graph, it is clear that the coordinates of A and B are A(1,3) and B(5,1).
The rule of translation is
[tex]f(x,y)\to (x-6,y-3)[/tex]
Using this rule, we get
[tex]A(1,3)\to A'(1-6,3-3)[/tex]
[tex]A(1,3)\to A'(-5,0)[/tex]
And,
[tex]B(5,1)\to B'(5-6,1-3)[/tex]
[tex]B(5,1)\to B'(-1,-2)[/tex]
Therefore, the coordinates of A' and B' are A'(-5,0) and B'(-1,-2).
