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

Can someone explain to how change a percent to a fraction is really confused

stealth61 [152]

For example,
45/100 In decimal would be 0.45
45/1000 in decimal would be 0.045.
I didn't really explain, but I gave an example. Hope this helped you?

How I do this? 3x+4y=11 X-2y=-3

Amanda [17]

Answer:

$\huge\boxed{x=1,\ y=2\to(1,\ 2)}$

Step-by-step explanation:

$\left\{\begin{array}{ccc}3x+4y=11\\x-2y=-3&\text{multiply both sides by (-3)}\end{array}\right\\\\\underline{+\left\{\begin{array}{ccc}3x+4y=11\\-3x+6y=9\end{array}\right}\qquad\text{add both sides of the equations}\\.\qquad\ \ \ \ 10y=20\qquad\text{divide both sides by 10}\\.\qquad\qquad\boxed{y=2}\\\\\text{subtitute it to the second equation:}\\x-2(2)=-3\\x-4=-3\qquad\text{add 4 to both sides}\\\boxed{x=1}$

The owners of a coffee shop conducted a taste test to determine whether its customers preferred a new coffee brand to the curren

yulyashka [42]

Answer:

Descriptive Statistics

Step-by-step explanation:

There are mainly two types of Statistics:

1) Descriptive Statistics

Descriptive statistics provide simple summaries about the sample and the measures. When using descriptive statistics you are simply describing what the data shows.

2) Inferential Statistics

On the other hand, inferential statistics try to reach conclusions that extend beyond the immediate data alone.

In this case the decision made was based on the "90% of the taste testers preferred", and no more than that.
