Lilly has $35,she went to the store and spender 10% of it,how much money she has left?

kirill115 [55]

Hi there! Lily has $31.50 left.

To find our answer we first need to know the amount of money Lily spend.
$10\% \times 35 = 0.1 \times 35 = 3.50$

Therefore, Lily spend $3.50. Now we subtract this amount of money from the amount she initially owned.

$35 - 3.50 = 31.50$
Hence, Lily has $31.50 left.

Verify csc^2t-cos t sect= cot^2 t

slega [8]

Rewriting the left hand side,

csc²t - cost sec t

= (1/sin²t)-(cost)(1/cost)

= 1/sin²t - 1

= 1/sin²t - sin²t/sin²t

= (1-sin²t)/sin²t

= cos²t/sin²t

= cot²t

Can you find the Triangle’s perimeter I’m marking branliest.

trasher [3.6K]

Answer:

P = 12x - 9

Step-by-step explanation:

To find the perimeter of the triangle, we just add all of the sides.

The formula is:

P = a + b + c

Given:

a = 5x - 6

b = 4x - 3

c = 3x

Work:

P = a + b + c

P = 5x - 6 + 4x - 3 + 3x

P = 12x - 9
