Find y. Round to the nearest tenth: 290 500 ft y X y = [ ? ]ft

hjlf

Answer:

y = 242.4

x = 437.3

First find the inner angle:

90° - 29°

61°

[ given hypotenuse = 500 ft ]

using sine rule:

$\sf sin(x)= \dfrac{opposite}{hypotensue}$

$\hookrightarrow \sf sin(61)= \dfrac{x}{500}$

$\hookrightarrow \sf x=sin(61)*500$

$\hookrightarrow \sf x=437.3$

using pythagoras theorem:

a² + b² = c²

y² + (437.3)² = 500²

y = √58760.1

y = 242.4

Step-by-step explanation:

${9}^{ \frac{3}{2} } \times {27}^{ \frac{1}{2} } = {(3)}^{ \frac{3}{2} \times 2 } \times {(3)}^{ \frac{1}{2} \times 3} \\ = {3}^{3} \times {3}^{ \frac{3}{2} } \\ = {3}^{3 + \frac{3}{2} } \\ = {3}^{4\frac{1}{2} } \\ = {3}^{ \frac{9}{2} }$

A group of friends is addressing wedding invitations. Casey can address 23 envelopes in one hour, Anne can address 45 envelopes

vlabodo [156]

Answer:

"4.71" is the correct answer.

Step-by-step explanation:

As we know, 45 envelopes addressed in 2 hours then,

⇒ $\frac{45}{2} =22.5$

and, 45 in 3 hours,

⇒ $\frac{61}{3}=20.3$

Now by adding all together, we get

⇒ $23+22.5+20.3$

⇒ $65.8$

and multiply it by "4.71", we get

⇒ $65.8\times 4.71$

⇒ $309.91$

Round it "310".

So that "4.71" is the right answer.
