The area of a triangle is calculated by the expression given as:

Area = bh/2

where b is the base and h is the height.

We calculate as follows:

270 = b (15) / 2

b = 36

hypotenuse = sqrt ( 15^2 + 36^2 ) = 39

A^2+b^2=1305, a*b=648, a-b=?

luda_lava [24]

a - b is 9

Step-by-step explanation:

Step 1: Given a² + b² = 1305, a × b = 648. Find a - b using the identity for (a - b)²

⇒ (a - b)² = a² + b² - 2ab

⇒ (a - b)² = 1305 - 2 × 648 = 1305 - 1296 = 9

⇒ (a - b) = 9

Two cooks purchased plates and cups at the same store. The first cook bought 4 plates and 5 cups for a total of $25.25. The seco

X=number of plates
y=number of cups

4x+5y=25.25

7x+3y=25.50

Add the two equations together:

11x+8y=50.75
11x=50.75-8y

x= $\frac{50.75-8y}{11}$

Plug x into the first equation:
4x+5y=25.25

4( $\frac{50.75-8y}{11}$ ) = 25.25

$\frac{4(50.75-8y)}{11}$ = 25.25

$\frac{203-32y}{11}$ = 25.25

203-32y = 277.75

-32y=74.75
32y=-74.45
y=2.34 (rounded to nearest hundredth)

The price of a plate is $2.34
