Answer:
Discounted price= $40.28
Step-by-step explanation:
Giving the following information:
A store is running a sale where all of the items are 35% off the normal price. The price of a video game you want to buy is normally $61.97.
<u>To calculate the discounted selling price, we need to use the following formula:</u>
Discounted price= selling price*(1 - discount rate)
Discounted price= 61.97*(1 - 0.35)
Discounted price= $40.28
Answer:x^3+13x^2+3
Step-by-step explanation:
(2x^3+11x^2+5)-(x^3-2x^2+2)
Clearing brackets
2x^3+11x^2+5-x^3+2x^2-2
Collect like terms
2x^3-x^3+11x^2+2x^2+5-2
x^3+13x^2+3
It would be A. R= 50 +10m
Answer:
w = 7m
l =9 m
Step-by-step explanation:
Let w = width
l = w+2
A = l*w
63 = (w+2) * w
63 = w^2 +2w
Subtract 63 from each side
0 = w^2 +2w - 63
Factor
What 2 numbers multiply to -63 and add to 2
9*-7 = -63
9-7 = 2
0 = (w +9) ( w-7)
Using the zero product property
w+9 =0 w-7 =0
w = -9 w = 7
Since we cannot have a negative length
w=7
l =w+2 =7+2 = 9
Given:
The track is a square with a half circle on its left and right sides.
The area of the square is 128 square feet.
To find:
The length of the track.
Solution:
Let side length of the square be x.
Area of square is
Taking square root on both sides.
From the given table 127.7 is closed to 128. So, 
is 11.3.
Diameter of circle = Side of square = 11.3.
The track has 2 sides of the square and the distance around 1 complete circle(s).
Radius of circle is
Length of the truck is sum of length of square and radii of two circles.
Therefore, the total length of the truck is 22.6 feet.
