A store sold 650 bicycles last year this year the store sold 572 bicycles what is the percent decrease in the number of bicycles sold from last year to this year?
Answers
How?
572/650=?/100
572 divided by 650= 88
100-88=12

Part B: How can you graph the equation obtained in Part A for the first six hours? (5 points)
Answers
Find the slope of the line segment that connects the points (3 hr, 51 km/hr) and (5 hr, 59 km/hr). Graph this line. Where does this line intersect the y-axis? Find the y-value; it's your "y-intercept," b.
Now write the equation: velocity = (slope of line)*t + b
The units of measurement of "slope of line" must be "km per hour squared," and those of the "y-intercept" must be "km per hour."
Part B: Start with the y-intercept (calculated above). Plot it on the vertical axis of your graph. Now label the horizontal axis in hours: {0, 1, 2, 3, 4, 5, 6}. Draw a vertical line through t=6 hours. It will intercept both the horiz. axis and the sloping line representing the velocity as a function of time. Show only the part of the graph that extends from t=0 hours to t=6 hours.

x² + 12x = l * x
A.
First, you factor x from x² + 12x
area = x (x+12)
area = (x+12) * x
Length = x + 12
B.
If x = 10,
l = x + 12 = 10 +12 = 22
length = 22
and
Area = x² + 12x = 10² + 12(10) = 100 + 120 = 220
area = 220
Hope this helps :)

a and b are legs
c=hypotnuse
a^2+b^2=c^2
10^2+b^2=10^2
100+b^2=100
minus 100 both sides
b^2=0
b=0
false, if you have a leg legnth 0, then they lines are right on top of each other
no cannot
To solve this problem we have to use the Pythagorean theorem. You can only use the Pythagorean theorem in Right Triangles. The longest side of the triangle is called the "hypotenuse". C² is the longest side so it is the hypotenuse . To calculate c² we have to do α² + β² = c².
Given
α² = 10
c² = 10
Solve
α² + β² = c²
α² (10²) + β² = c² (10²)
100 + β² = 100
β² = 100 - 100 = 0
Simplify
A right triangle can not have a leg that is 10 meters long and a hypotenuse that is 10 meters long.

rearrange 8 × x + 4 - (44) = 0
Step one: 8x - 40 = 8 × ( x - 5)
Step 2 : Solve 8 = 0
Step 2 (part 2) : Solve x - 5 = 0
So, your answer would be x= 5
8x = 40
x = 40/8
x = 5
