) What would the value of c be when

jasenka [17]

The value of c is 233.3

Step-by-step explanation:

Given equation is:

$\frac{18}{20}c-250=-40$

To find the value of c, we have to isolate c on one side of the equation

So,

Adding 250 on both sides

$\frac{18}{20}c-250+250=-40+250\\\frac{18}{20}c=210$

Multiplying by 20 on both sides

$20*\frac{18}{20}c=210*20\\18c=4200$

Dividing both sides by 18

$\frac{18c}{18}=\frac{4200}{18}\\c=233.3333$

Rounding off to the nearest one decimal place

c=233.3

The value of c is 233.3

HELP!! PLEASE A carpenter is framing a window with wood trim where the length of the window is 9 and 1/3 feet. If the width of t

ohaa [14]

We need the perimeter of the window for framing

The window is in the shape of a rectangle with the height of $9 \frac{1}{3}$ feet and width of $6 \frac{3}{4}$ . The diagram of the shape is shown below

The perimeter of a shape is obtained by adding up the length of all the sides that form the shape.

The perimeter of the window is $9 \frac{1}{3}+9 \frac{1}{3}+6 \frac{3}{4}+6 \frac{3}{4}$ = $18 \frac{2}{3}+12 \frac{6}{4}$

We have two whole numbers 18 and 12 and two fractions $\frac{2}{3}$ and $\frac{6}{4}$

Adding the two fractions that have different denominator
$\frac{2}{3}+ \frac{6}{4} = \frac{8}{12}+ \frac{18}{12}= \frac{26}{12}$ , which is an improper fraction which we can change into a mixed number $2 \frac{1}{6}$

So the perimeter of the window is
$18+12+2 \frac{1}{6} =32 \frac{1}{6}$

and the length of wood needed for the frame is $32 \frac{1}{6}$ feet
