Martine’s town is building a volleyball court based on a scale drawing that is 40cm to 80cm and uses the scale 1cm:22.5cm write

never [62]

Answer:

$y=22.5x$

Step-by-step explanation:

we have that

The scale drawing is

$\frac{1}{22.5}\frac{cm}{cm}$

we know that

Using proportion find out the actual dimensions of the volleyball court

Let

x -----> drawing court lengths in cm

y ----> court lengths in cm

For x=40 cm

$\frac{1}{22.5}\frac{cm}{cm}=\frac{40}{y}\frac{cm}{cm}\\\\y=40*22.5\\\\y=900\ cm$

For x=80 cm

$\frac{1}{22.5}\frac{cm}{cm}=\frac{80}{y}\frac{cm}{cm}\\\\y=80*22.5\\\\y=1,800\ cm$

Find the equation for the proportional relation ship between drawing court lengths x in centimeters and court lengths in y centimeters

A relationship between two variables, x, and y, represent a proportional variation if it can be expressed in the form $y/x=k$ or $y=kx$

For x=40 cm, y=900

substitute

$k=y/x$ -----> $k=900/40=22.5$

The equation is

$y=22.5x$

When 0.5(20x – 50y + 36) – 0.25(–100x + 40y – 12) is simplified, what is the resulting expression?

stiks02 [169]

Answer:

solution,

$0.5(20x - 50y + 36) - 0.25( - 100x + 40y - 12) \\ = 10x - 25y + 18 + 25x - 10y + 3 \\$

Combine the like terms:

$= 10x + 25x - 25y - 10y + 18 + 3 \\$

Simplify:

$35x - 35y + 21$

Hope this helps...

Good luck on your assignment...

A basketball player completed 44.2% of his field goals in the most recent season. He made 287 field goals. How many did he att

Andrej [43]

44.2%= 287

Let the total attempt = x

(287/x) ×100 = 44.2

287/x = 44.2/100

287/x = 0.442

x = 287/0.442

Hope this will help...

How do i find the value of x , i’m so confuseddd !

olasank [31]

Answer:

x ≈ 61.3

Step-by-step explanation:

Using the Sine rule, that is

$\frac{6}{sinx}$ = $\frac{5.8}{sin58}$ ( cross- multiply )

5.8 × sinx = 6 × sin58° ( divide both sides by 5.8 )

sin x = $\frac{6sin58}{5.8}$ ≈ 0.87729, thus

x = $sin^{-1}$ (0.87729) ≈ 61.3
