A
Step-by-step explanation:
Given:
The first customer paid $17 for 7 small envelopes and 3 memo pads.
The second customer paid $28.75 for 12 small envelopes and 5 memo pads.
To find:
The cost in dollars of each memo pad.
Solution:
Let x be the cost of each small envelop and y be the cost of each memo pad.
The first customer paid $17 for 7 small envelopes and 3 memo pads.
...(i)
The second customer paid $28.75 for 12 small envelopes and 5 memo pads.
...(ii)
Multiply equation (i) by 12 and equation (ii) be 7 to get same coefficient of x.
...(iii)
...(iv)
Subtracting (iv) from (iii), we get
Therefore, the cost of each memo pad is $2.75.
First taking small triangle,
Perpendicular(P') = 5cm
Base(B) = y (let)
Hypotenuse(H') = 12cm
so,
(H')² = (P')² + (B)²
(12)² = (5)² + (y)²
(y)² = 144 - 25
(y)² = 119
Now taking big triangle,
Perpendicular (P) = 12+5 = 17cm
Base (B) = y (already supposed)
Hypotenuse (H) = x
so,
(H)² = (P)² + (B)²
(x)² = (17)² + (y)²
(x)² = 289 + 119 = 408
x = √408
