The product has decreased by 80 %
<em><u>Solution:</u></em>
The product of the original numbers: xy
One number is decreased by 75 %
Let x be the number decreased by 75 %
new number = x - 75 % of x
Another number is decreased by 20 %
Let y be the number decreased by 20 %
new number = y - 20 % of y
<em><u>Now the product is given as:</u></em>
<em><u>Now we have to find the percent decreased</u></em>
Subtract new product and original product and then divide by original product . Multiply the result by 100 to get percentage
Here negative sign denotes decrease
Thus the product has decreased by 80 %
Answer:
Option 1
Step-by-step explanation:
5(3x+2) + 2(x-7)
15x + 10 + 2x -14
15x + 2x + 10 - 14
17x - 4
I think that whole numbers and natural numbers are the same set:- 1, 2, 3, 4 etc
The total charges for the first club as a function of the number of rentals (x) are
... f1 = 25 + 2.50x
The total charges for the second club are
... f2 = 3.25x
We want to find x so that f1 < f2.
... f1 < f2
... 25 + 2.50x < 3.25x
.. 25 < 0.75x . . . . . . . . . . subtract 2.50x
... 25/0.75 < x . . . . . . . . . divide by the coefficient of x
... 33 1/3 < x
You must rent 34 videos or more to make the first club more economical.
First is to understand the terms. Lateral area is the surface area of a 3D figure, excluding the area of any base.
<span>Laterial Area (L.A.) of a right cone = pi*radius*slant height </span>
<span>radius = 1/2 * diameter </span>
<span>L.A. = pi*(1/2)*(4)*(15)=30*pi </span>
<span>the formula for this is pi*r*rt(r^2 + h^2). If the diameter is 4, then the radius is 2. If the slant height is 15, then to get the real height we use the Pythagorean Theorem and get rt(221). So the lateral area is pi*2*rt(2^2 + (rt221)^2)...= 2pi*rt(225) = 30pi = 94.248 meters squared which is rounded to 94 meters squared.</span>
