Answer:
a) Similar triangles are triangles with the same shape but not necessarily the same size
b) 15/45 = 8/x
1/3 = 8/x (simplify the 15/45)
x = 8 * 3 (cross multiplication)
x = 24
c) y^2 = 15^2 + 8^2 (Pythagoras theorem)
y = *square root of* 15^2 + 8^2
y = 17
1/3 = 17/z
z = 17 * 3 (cross multiplication)
z = 51
Answer:
Where's the line?
Step-by-step explanation:
David paid $22 for the beanie baby.
Profit and loss formulas are used to calculate the profit or loss that has been incurred by selling a particular product. They are mainly used in business and financial transactions to depict how much profit or loss a trader has incurred from any particular deal.
Let the cost which David pay for the beanie baby be x and y be the price at which Jessica bought the beanie baby
Profit formula :
Profit = Selling price (S.P.) - Cost price (C.P.)
So using the profit formula
$6 = $25 - y
$19 = y
Now using the same equation for David
-$3 = $19 - x
$22 = x.
Thus David paid $22 for the beanie baby.

Median is 43.65 and the mean is 45.5.
First u put the number in order of smallest to largest.
The median is the middle numbers and since there is a even number u add up the 2 middle numbers and divide by 2.
The mean is the average so u add up all the numbers and divide by how ever many there are.
