1)
36/3 x 42/3 = 12yd x 14yd

12×14=168

you will need 168 square yards to recarpet the kindergarten.

2)
168×24.99=4198.32

it will cost $4198.32 to recarpet the kindergarten.

3)
3.5 is 35% of 10

4198.32÷3.5=1198.52

they will need to sell 1199 coupon books to completely pay for the the recarpeting.

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

$y=22.5x$

Nina asked 30 of her friends what they thought about a new movie.

Sunny_sXe [5.5K]

No, this is not a random group of students. Because Nina asked her friends if they liked the movie. For her to ask a random group of people, she would have to go and ask people that she did not know.
