a sketch of a fashion designer's shirt is 9cm long. the actual shirt is 1 meter long. What is the scale of the drawing?

Softa [21]

You can solve for (T)

$y = - 16t {}^{2} + 400 \\ add \: both \: side \: by \: - 16t {}^{2} \\ - 16t {}^{2} = - 400 \\ divide \: both \: side \: by16 \\ t {}^{2} = - 25 \\ t = \sqrt{25} \\ t = 5 \\ \: also \: it \: can \: be \: - 5 \\ + - 5 \\ \\$

Hope this help :)

P=3h+3u solve for h ...?

horrorfan [7]

p=3h + 3u subtract 3u from both sides

p-3u=3h now divide both sides by 3

h = p/3 - u

What is Xavier’s available lot coverage?

slavikrds [6]

Answer:

Step-by-step explanation:

<h3>At first:</h3>

Given,

Back of lot of the trapezoid = 175

Front of lot of the trapezoid = 185

Length of lot of the trapezoid = 100

Therefore, 

Area of the trapezoid

$= \frac{a + b}{2} c$

[On putting the values]

$= \frac{175 + 185}{2} \times 100$

[On Simplification]

= 360 × 50

[On multiplying]

= 18000

Hence,

We got the Total Area as 18000.

As per given equation,

$\frac{40}{100} = \frac{x}{total \: area}$
To find the value of x

Solution ,

$= > \frac{40}{100} = \frac{x}{total \: area}$

[On putting Total Area = 18000]

$= > \frac{40}{100} = \frac{x}{18000}$

[On cross multiplication]

=> 40 × 18000 = 100 × x

[On Simplification ]

=> 720000 = 100x

[On dividing both sides with 100]

$= > \frac{720000}{100} = \frac{100x}{100}$

[On Simplification ]

=> x = 7200

Hence,

Xavier's avaliable lot coverage (x) = 7200 (Ans)
