В рулоне 32 метров ткани. Отрезали одну восьмую часть. Сколько

chubhunter [2.5K]

Answer:

28 meters

Step-by-step explanation:

<u><em>The question in English is</em></u>

On a 32-meter roll of fabric, it cuts an eighth of the total. How many meters of fabric are left in a roll?

step 1

we know that

To find out how many meters of fabric were cut, multiply the total meters by the fraction that was cut

$32(\frac{1}{8})=4\ m$

step 2

To find out how many meters of fabric are left, subtract the meters of fabric that were cut from the total meters of fabric

so

$32-4=28\ m$

A clothing manufacturer uses the model a=f+4−−−−√−36−f−−−−−√ to estimate the amount of fabric to order from a mill. In the formu

Questions:

A clothing manufacturer uses the model a = √(f + 4) - √(36 - f) to estimate the amount of fabric to order from a mill. In the formula, a is the number of apparel items (in hundreds) and f is the number of units of fabric needed. If 400 apparel items will be manufactured , how many units of fabric should be ordered?

Answer:

32 units of fabrics

Step-by-step explanation:

Given

$a = \sqrt{f + 4} - \sqrt{36 - f}$

Required

Find f when a = 4

Substitute 4 for a

$4 = \sqrt{f + 4} - \sqrt{36 - f}$

Rewrite as:

$\sqrt{36 - f} + 4 = \sqrt{f + 4}$

Square both sides

$(\sqrt{36 - f} + 4)^2 = (\sqrt{f + 4})^2$

$(\sqrt{36 - f} + 4)^2 = f + 4$

$36 - f + 8\sqrt{36 - f} + 16 = f + 4$

Collect Like Terms

$8\sqrt{36 - f}= f +f+ 4 - 36 -16$

$8\sqrt{36 - f}= 2f -48$

Divide through by 2

$4\sqrt{36 - f}= f -24$

Square both sides

$16(36-f) = (f - 24)^2$

$16(36-f) = f^2 - 48f + 576$

$576-16f = f^2 - 48f + 576$

$-16f = f^2 - 48f$

Collect like terms

$f^2 - 48f + 16f = 0$

$f^2 -32f = 0$

Factorize

$f(f - 32) = 0$

$f = 0$ or $f = 32$

f can not be 0 because some units must be ordered.

So, f = 32

A rectangle with an area of 192 square meters has a length and width in a ratio of 3:1. What are the length and width?

yuradex [85]

Hey there! :)

Answer:

Length = 24 meters.

Width = 8 meters.

Step-by-step explanation:

Recall that to find the area of a rectangle, the formula is as shown:

A = l × w

In this case, the length is 3 times the length of the width, or 3 : 1.

Let w = width, and

3w = length.

Find the value of w by plugging in these values into the equation:

192 = 3w · w

192 = 3w²

Divide both sides by 3:

64 = w²

Square root both sides:

w = 8 meters. This is the width.

The length is equivalent to 3w, so:

3(8) = 24 meters.

Let's call Frank's house F, Derek's one D n Evan's E.

F(5,-4)
E(-3,-4)
D(-3,4)

FE=5-(-3)=5+3=8
ED=4-(-4)=4+4=8

We can see the triangle is a half of a square, so FD is 8(√2)≈11.312

11.312+8=19.312

The answer is C.19.31
