Answer:18.5m

1m=100cm

Let lenght of streamers in meters be x

Then(1/100)=(x/1850)

(1850/100)=x

18.5m=x

The area of a rectangular piece of land is 5/16 square mile. .

tatiyna

Answer:

Step-by-step explanation:

Area = L * W

L = 1/2

Area = 5/16

5/16 = 1/2 * w You could do this using decimals

5/16 = 0.3125

1/2 = 0.5

0.3125 = 0.5 * w

w = 0.3125/0.5

w = 0.625

w = 5/8

The other way is done by fractions

$\frac{\frac{5}{16} }{\frac{1}{2} } = \frac{5}{16}*\frac{2}{1} =\frac{5}{8}$

There are a couple of notes

First, you invert and multiply the denominator (the bottom fraction). It becomes 2/1
Second the 2 and 16 cancel 5/16 becomes 5/8

What should be added to a²-2ab+b² to get a²-ab-2b²

<u>SOLUTION</u><u>:</u>

<u>what should be added to a²-2ab+b² to get a²-ab-2b² </u>

let the added no is P

$\pmb{P+(a^2-2ab+b^2)=(a^2-ab-2b^2) }$

$\pmb{P=(a^2-ab-2b^2)-(a^2-2ab+b^2) }$

$\pmb{P=a^2-ab-2b^2-a^2+2ab-b^2 }$

$\pmb{P=ab-3b^2 }$

$\therefore{\pmb{ab-3b^2 }}$ should be added to a²-2ab+b² to get a²-ab-2b²

The drama club is printing t-shirts for its members. The printing company charges a certain amount for each shirt plus a setup f

Setler [38]

Answer: $7.

Step-by-step explanation:

It is given that the printing company charges a certain amount for each shirt plus a setup fee of $40.

Let x be the cost of each t-shirt.

There are 21 students in the drama club. So, total cost of 21 t-shirts is

$\text{Total cos}=40+21x$

It is given that the t-shirt order costs a total of $187.

$40+21x=187$

$21x=187-40$

$21x=147$

Divide both sides by 21.

$x=\dfrac{147}{21}$

$x=7$

Therefore, the cost of each t-shirt is $7.
