Given :
Total amount, T = 10000 . ( It should not 1000 )
Annual rates of interest in both scheme is 8% and 9% .
After one year he got 875 rupees as interests from both.
To Find :
How much did he invest in each.
Solution :
Let, amount invested in 8% annual interest scheme is x.
So, amount in other scheme is 10000-x .
Now, sum of interest is equal to 875.
[tex]\dfrac{x\times r_1 \times 1}{100}+\dfrac{(10000-x)\times r_2\times 1}{100}=875\\\\8x + 9(10000-x)=87500\\\\x = 90000-87500\\\\x = 2500[/tex]
Therefore, amount invested in 8% and 9% annual interest scheme is 2500 and 7500 rupees respectively.
Hence, this is the required solution.

Which function has the same graph as x + y = 11?
A.
f(x) = -y + 11
B.
f(x) = -x + 11
C.
f(x) = x − 11
D.
f(x) = y − 11
Answer:
B. f(x) = -x + 11Step-by-step explanation:
y = f(x)
therefore
x + y = 11 → x + f(x) = 11 |subtract x from both sides
x - x + f(x) = 11 - x
f(x) = -x + 11
The correct function is f(x) = 11 - x, has the same graph as x + y = 11, which corresponds to option B.
Therefore, the correct answer is:
B. f(x) = -x + 11
Here,
To find the function with the same graph as x + y = 11,
we need to isolate y in the equation to make it of the form y = f(x).
Given equation: x + y = 11
Subtract x from both sides of the equation:
y = 11 - x
Now, we have the equation in the form y = f(x).
so, we get, f(x) = -x + 11
i.e. The function which has the same graph as x + y = 11 is: f(x) = -x + 11
so, we have,
The correct function is f(x) = 11 - x, has the same graph as x + y = 11, which corresponds to option B.
Therefore, the correct answer is:
B. f(x) = -x + 11

The link between the bases on a basketball field is 93 a scale drawing shows the distance between the Bases as 1 1/2 to 1 inch on the drawing equals how many feet
Answer:
Distance on drawing is 11.7 feet.
Step-by-step explanation:
A scale is a factor that can be used to either increase or decrease the size of an object.
Scale = [tex]\frac{distance on drawing}{original distance}[/tex]
Given that:
scale = [tex]\frac{3}{2}[/tex] to 1 inch, and the original distance = 93 inches
So,
[tex]\frac{3}{2}[/tex] : 1 = [tex]\frac{distance on drawing}{93}[/tex]
[tex]\frac{3}{2}[/tex] ÷ 1 = [tex]\frac{distance on drawing}{93}[/tex]
[tex]\frac{3}{2}[/tex] x [tex]\frac{1}{1}[/tex] = [tex]\frac{distance on drawing}{93}[/tex]
distance on drawing = [tex]\frac{3*93}{2}[/tex]
= [tex]\frac{279}{2}[/tex]
= 139.5
distance on drawing = 139.5 inches
Since 12 inches = 1 foot, then;
Distance on drawing in feet = [tex]\frac{139.5}{12}[/tex]
= 11.625 feet
Distance on drawing is 11.7 feet.

factory has supplies expenses of $1135.78 a day, in addition to the wages above and makes $60,128.72 in one week, what is the factory's total profit or loss in one week?
Answer:
A= $54144B= loss of $829.96 per weekStep-by-step explanation:
The question is incomplete, here is the detailed version:
A) A certain small factory employs 98 workers. Of these, 10 receive a wage of $150 per day and
the rest receive $85.50 per day. To the management, a week is equal to 6 working days. How much
does the factory pay out for each week?
B) If the same factory has supplies expenses of $1,135.78 a DAY in addition to the wages above
and makes $60,128.72 in a week, what is the factory’s total profit or loss in one week? .
A. The total pay per week
= (10(150)+88(85.5))*6
=(1500+7524)*6
=9024*6
=$54144
B. The factory’s total profit or loss in one week.
= 60,128.72-(54144+6(1135.78))
=60128.72-(54144+6814.68)
=60128.72-60958.68
= -829.96
The factory will make a loss of $829.96 per week
A snack bar at an outdoor fair is open from 10 A.M. To 5:30 P.M. And has 468 bottles of water for sale. Sales average 1.3 bottles of water per minute.
Answer:
the question is incomplete, so I looked for similar ones
the number of bottles of water remaining as a function of time:
f(x) = -78x + 468
1.3 bottles are sold per minute x 60 minutes per hour = 78 bottles per hour
x = number of hours
the slope is -78
the y intercept is 468
domain = 0 ≤ x ≤ 7.5 hours (from 10 AM to 5:30 PM)
range = 0 ≤ y ≤ 468 bottles
the snack will run out of bottles of water by 4 PM
78x = 468
x = 468 / 78 = 6 hours
if the snack wants to have enough bottles of water to serve all its customers, it will need:
78 x 7.5 hours = 585 bottles of water

Answer:
y+1 = 3/4(x-1)Step-by-step explanation:
Given the coordinates of a line, (1, -1) and (5, 2), we are to find the equation of the line in point-slope form.
The point slope form of the equation is generally expressed as;
y -y0 = m(x-x0)
m is the slope
(x0, y0) is the point
Get the slope first;
m = y2-y1/x2-x1
m = 2-(-1)/5-1
m = 3/4
Substitute any of the point sat=y (1, -1) and m = 3/4 into the point slope form of the equation
y - (-1) = 3/4 (x-1)
y+1 = 3/4(x-1)
Hence the required equation is y+1 = 3/4(x-1)

Find the maximum height of the rocket and explain in at least threes sentence how you calculated your answer of y = - 16x ^ 2 + 480x
Answer:
The maximum height of the rocket is 3600
Step-by-step explanation:
The vertex of the quadratic equation y = ax² + bx + c is (h, k), where
h = [tex]\frac{-b}{2a}[/tex]k = y at x = hThe vertex (h, k) is a minimum point if a is positive The vertex (h, k) is a maximum point if a is negativeThe height of the rocket calculated using the equation y = -16x² + 480x, where y is the height and x is the time
To find the maximum height, do that
Find the x-coordinate of the vertex of the equation ⇒ hSubstitute the value of x in the equation by h to find the y-coordinate of the equation ⇒ kThe maximum height equal the value of kLet us do that
∵ y = -16x² + 480x
∴ a = -16 ⇒ the vertex is a maximum point
∴ b = 480
→ Use the rule above to find h
∵ h = [tex]\frac{-b}{2a}[/tex]
∴ h = [tex]\frac{-480}{2(-16)}[/tex] = [tex]\frac{-480}{-32}[/tex]
∴ h = 15
∵ k = y at x = h
→ Substitute x by 15 in the equatuion and y by k to find x
∵ k = -16(15)² + 480(15)
∴ k = -3600 + 7200
∴ k = 3600
∵ The maximum height equal the value of k
∴ The maximum height of the rocket is 3600

In December of 2003, the average price for a gallon of regular gas in the United States was $1.50.
b. Is the relationship between number of gallons and cost proportional? Explain.
Answer:
yes
Step-by-step explanation:
because the cost stays the same and you would multiply blank gallons of gas by 1.50 every time so it is proportional. For example: it would be $1.50 to 1 gallon, $3 to 2 gallons, $4.50 to 3 gallons and would keep going like that, adding the same amount every time

What are the coordinates of point \green{B}Bstart color #28ae7b, B, end color #28ae7b?
Answer:
(7,4)
Step-by-step explanation:
The midpoint formula is expressed as:
M(X, Y) = {(x2+x1)/2, (y2+y1)/2
Given the coordinates of the midpoint
M(2.5, -1.5)
Endpoint A(-2, -7)
Required
Endpoint B
From the formula;
X = x2+x1/2
Given
X = 2.5, x1 = -2
Get x2
2.5 = -2+x2/2
5 = -2+x2
x2 = 5+2
x2 = 7
Also
Y = y2+y1/2
-1.5 = -7+y2/2
-3 =-7+y2
y2 = -3+7
y2 = 4
Hence the coordinate of the endpoint B (x2,y2) is (7,4)
