During a sale, a shopkeeper reduced the prices of all his goods by 25%.
Calculate the normal selling price of a pair of shoes which was sold for Rs 1350 in the sale.
Answer:
1800
Step-by-step explanation:
Let y represent the normal selling price
y-y×25/100= 1350
y-y/4= 1350
4y-y/4= 1350
3y/4 = 1350
Cross multiply both sides
3y= 1350×4
3y= 5400
Divide both sides by the coefficient of y whichj is 3
3y/3= 5400/3
y= 1800
Hence the normal selling price is 1800

The table below shows the values of f(x) and g(x) for different values of x. One of the functions is a quadratic function, and the other is an exponential function. Which function is most likely increasing exponentially?
Answer:
G(x) or at least in the question i hae seen but i do not see your table so just gonoff of what i say below becase it might be f(x)
Step-by-step explanation:
Exponetial funtions are when you have a power of, for example g(x)=1+6x^2
It increases at a rather fast pace because of the power of 2 in this equaion when if it did not have thepower of 2 it would increase at a slower pace

Answer:
R = 101
S = 131
Step-by-step explanation:
First, you will want to get your angle T. Since T is on the same line as the angle with 128 degree, you can easily find angel T. They are supplementary angels and form 180.
T=180-128
T=52
You also know that all angles in a triangle equal to 180
Use that to find angle S
180 = R+S+T
180 = 79 + S + 52
180 - 79 - 52 = S
49 = S, exterior S = 180-49 = 131
Exterior R = 180 - 79 = 101
Now add all your exteriors
Which equation in point -slope form describes the line that passes through the point (4,-5) and is perpendicular to the line represented by -7x+2y=14.
Answer:
[tex]y+5=-\frac{2}{7} (x-4)[/tex]
Step-by-step explanation:
Hi there!
What we need to know:
Linear equations are typically organized in slope-intercept form: [tex]y=mx+b[/tex] where m is the slope and b is the y-intercept (the value of y when the line crosses the y-axis)Point-slope form: [tex]y-y_1=m(x-x_1)[/tex] where the given point is [tex](x_1,y_1)[/tex] and m is the slopePerpendicular lines always have slopes that are negative reciprocals (ex. 2 and -1/2, 3/4 and -4/3)1) Determine the slope (m)
[tex]-7x+2y=14[/tex]
First, rearrange this given equation into slope-intercept form ([tex]y=mx+b[/tex]) so we can easily find the slope.
Add 7x to both sides to isolate 2y
[tex]-7x+2y+7x=7x+14\\2y=7x+14[/tex]
Divide both sides by 2 to isolate y
[tex]y=\frac{7}{2} x+7[/tex]
Now, we can identify clearly that the slope of this line is [tex]\frac{7}{2}[/tex]. Because perpendicular lines have slopes that are negative reciprocals, we know that the slope of the line we're currently solving for will have a slope of [tex]-\frac{2}{7}[/tex].
[tex]m=-\frac{2}{7}[/tex]
2) Plug all necessary values into [tex]y-y_1=m(x-x_1)[/tex]
[tex]y-y_1=m(x-x_1)[/tex]
We know that [tex]m=-\frac{2}{7}[/tex] and that the given point is (4,-5). Plug the slope into the equation
[tex]y-y_1=-\frac{2}{7} (x-x_1)[/tex]
Plug the point into the equation
[tex]y-(-5)=-\frac{2}{7} (x-4)\\y+5=-\frac{2}{7} (x-4)[/tex]
I hope this helps!

Answer:
A)-19,15,-9,-1,9
Step-by-step explanation:
that's the answer when I compute it
===================================================
Explanation:
If we plug in x = -2, then we get,
y = x^2 + 7x - 9
y = (-2)^2 + 7(-2) - 9
y = 4 - 14 - 9
y = -10 - 9
y = -19
So x = -2 leads to y = -19. The answer is between A and D.
---------
If you repeat those steps for x = -1, then you should get y = -15
Then x = 0 leads to y = -9
x = 1 leads to y = -1
Finally, x = 2 leads to y = 9
The outputs we get are: -19, -15, -9, -1, 9 which is choice A
Choice D is fairly close, but we won't have a second copy of -15, and we don't have an output of -19.

Applying the Pythagorean theorem, solve this triangle.
Answer:
20
Step-by-step explanation:
We can use the Pythagorean theorem since this is a right triangle
a^2+b^2 = c^2 where a and b are the legs and c is the hypotenuse
21^2 + b^2 = 29^2
441+b^2 =841
Subtract 441 from each side
441 +b^2 -441 = 841-441
b^2 = 400
Take the square root of each side
sqrt(b^2) = sqrt(400)
b =20

Find the area of the isosceles triangle
Answer:
Step-by-step explanation:The area of an isosceles triangle is the amount of space enclosed between the sides of the triangle. Besides the general area of the isosceles triangle formula, which is equal to half the product of the base and height of the triangle, different formulas are used to calculate the area of triangles, depending upon their classification based on sides. These different types based on sides are given below:
Equilateral Triangle- A triangle with all sides equal.
Isosceles Triangle- A triangle with any two sides/angles equal.
Scalene Triangle- A triangle with all unequal sides.

This year, water usage has increased by 20% for both regular days and special events.
LAST YEAR'S WATER USAGE:
All regular days - 13,505 gallons
Per special event - 18.5 gallons
Total for the year - 13,616 gallons
Write an equation for the total water usage, U, at the park this year in terms of x, the number of special events the park has hosted.
Answer:
The total water usage at the park this year, in gallons, U = 16,206 + 22.2·x
Step-by-step explanation:
The given parameters are;
The increase in water usage for both regular days and special event for the current year = 20%
The water usage for last year regular days = 13,505 gallons
The water usage per special event = 18.5 gallons
The total water usage = 13,616 gallons
Therefore, we have;
The water usage for regular days on the current year = 13,505 gallons + (20/100)×13,505 gallons = 16,206 gallons
The water usage per special event for the current year, x = 18.5 gallons + (20/100) × 18.5 gallons = 22.2 gallons
The total water usage, U, at the park this year in terms of 'x', the number of special events the park hosted is given by the sum of the amount of water used on regular days and the product of 'x', and the amount of water used per special event this year as follows;
U = 16,206 gallons + x × 22.2 gallons
∴ The total water usage at the park this year, U = 16,206 + 22.2·x
Answer:
U=16,206+22.2 ^. x

A rectangular is 11 inches long and 8 inches wide. Find its area
Answer:
The area is 88 square inches.
Step-by-step explanation:
To get the area of a rectangle, you multiply the length and the width.
The length of this rectangle is 11 inches and the width is 8 inches.
11x8=88
Tip: You can multiply by 11s easily if you replace the ones with the number you are multiplying. This only works for numbers up to 9 though.
Example:
11x5=55
11x2=22
