The percent change of 15 yards to 18 yards

Paladinen [302]

First we subtract it:

18 - 15 = 3

Now we divide it to the original:

3 / 15 = 0.2

Multiply by 100:

0.2 * 100 = 20%

one family spends $134 on 2 adult tickets and 3 youth tickets at an amusement park. Another family spends $146 on 3 adult ticket

Eddi Din [679]

Answer:

Let x be the price of an adult ticket and y be the price of a youth ticket.

One family spends $134 on 2 adult tickets and 3 youth tickets so we can write: 2x+3y=134

Another family spends $146 on 3 adult tickets and 2 youth tickets so we can write: 3x+2y=146

We need to find y so we eliminate x. Multiply (1) by 3 and (2) by 2 to obtain (3) and (4): 6x+9y=402

6x+4y=292

Subtract (3) and (4) and solve for y: 5y=110

y=22→$22

Aleksandr [31]

Answer:

G 328 ft

Step-by-step explanation:

$\cos(angleBAC) = \frac{AB}{AC}$

$\cos(55°) = \frac{AB}{400}$

AB = 229.431 ft

AB² + BC² = AC²

229.431² + h² = 400²

h = 327.659 ft ≈ 328 ft
