Slope = (y2 - y1)/(x2 - x1)
Slope = (212 - 32)/(100 - 0)
Slope = 180 / 100
Slope = 18/10
Slope = 9/5
Answer
D. slope = 9/5
Answer:
go where they do school on
Step-by-step explanation:
1728 cubic centimeters
12 with the exponent of 3 would basically be 12x12x12 but easier i put 12x12=144x12= which is 1728
cuz if its just 12x12 thats just the area of one side, if its 12x12x12 its the volume of the whole cube/rectangular prism
Answer:
5in x 10in
Step-by-step explanation:
Solution:
1. You have to assume that the ring will land on the board and as a result, just focus on one rectangle of the board since they are all the same size.
2. For the ring to land entirely inside the rectangle, the center of the ring needs to be 1.5 inches inside the border (radius is 1.5 inches), so the "winning rectangle" will have dimensions:
L = (x - 2(1.5)) = x - 3
w = (2x - 2(1.5)) = 2x-3.
3. Now, we will set up and solve our geometric probability equation. The winning rectangle's area of (x-3)*(2x-3) divided by the total rectangle's area of x*(2x) = 28%
(2x-3)*(x-3)/(2x^2) = .28
2x^2 - 9x + 9 = .56x^2
1.44x^2 - 9x + 9 = 0
4 . Now you can plug that in the quadratic formula and get the solutions x = 1.25 or 5. However, it cannot by 1.25 because that is too small of a dimension for the the circle with diameter of 3 to fit in, the answers has to be 5.
5. As a result, the dimensions of the rectangles are 5in x 10in.
Answer:
$331.25
Step-by-step explanation:
Given:
The jewelry center bought a pair of earrings for $250
They are going to mark the price of the earrings up 32.5%
Question asked:
How much will they sell the earrings for ?
Solution:
Cost price of a pair of earrings = $250
Mark up value = 32.5% of $250
= 
Now, we can find selling price of a pair of earring by simply adding the cost price and the mark up value.
Selling price = cost price + mark up value
= 250 + 81.25
= $331.25
Thus, they sell the earrings for $331.25
