mojhsa [17]

Answer:

11,448 in²

Step-by-step explanation:

The area can be computed from ...

... A = 2(LW +H(L+W))

For the given prism, the area will be ...

... A = 2(18·12 +14(18+12)) = 2(216 +420) = 1272 . . . . in²

The area of a similar figure with dimensions 3 times as long will be 3² times as much. The area of the new figure is ...

... A = 3²×(1272 in²) = 11,448 in²

Dafna11 [192]

Correct answer is 33.1 m.

Use The definition of trigonometric functions. The sine of an angle is the quotient of the opposite side and hypotenuse.

$sin{65^o}= \frac{30}{x} 
\\x= \frac{30}{sin{65^o}}
\\x=33.1

What is the solution to this system?<br> 3x+2y=45<br> 4x+-y=5

hodyreva [135]

(I) $3x + 2y = 45$

(II) $4x - y = 5$

Get $y$ alone in equation (II)

$4x - y = 5\\y = 4x - 5$

Insert new equation (II) in equation (I)

$3x + 2(4x - 5) = 45\\3x + 8x - 10 = 45\\3x + 8x = 45 + 10\\11x = 55\\x = 5$

Insert $x = 5$ in equation (II)

$y = 4 \cdot 5 - 5\\y = 20 - 5\\y = 15$
