ALEXANDRA BUYS SWEATSHIRTS FOR $12 EACH . IN HER STORE SHE SELLS EACH SWEATSHIRTS BY 25%

1 answer:

4 0

PLEASE DO NOT PUT QUESTIONS IN ALL CAPS. IT BECOMES VERY ANNOYING

so anyway
she sells each shirt at a 25% discount so each shirt is (100-25)%=75% in cost

percent means parts out of 100 so
75%=75/100=7.5/10=0.75
0.75 of 12
'of' is translated to as multipy
0.75 times 12=9
each shirt costs 9 dollars

2 shirts so
2 times 9
18
18
plus tax
x=4%
4%=4/100=0.04
18 times 0.04=0.72
tax=0.72
10+0.72=18.72
total cost is $18.72

U − -23 _______ = -8 -9 Solve for u Thanks!

Romashka [77]

Answer:

u=95

Step-by-step explanation:

To solve this problem we need to isolate 'u' variable using properties of equation.

Lets multiply by -9 the whole equation

u - -23=-8*9

Remember keys features of algebra:

- * - = +

- * += -

+ * - = -

+ * + =+

So, our equations becomes>

u+23=-72

Lets now subtract 23 to both sides

u-23=-72-23

We have u=95

Answer:

75.9375%

Step-by-step explanation:

We apply the simple interest formula;

we first determine the amount of accrued interest to be earned;

interest = 275000 - 32000

= 243000

Applying the simple interest formula;

$I=\frac{P*R*T}{100}\\243000=\frac{32000*R*10}{100}\\ 243000=3200R\\R=75.9375$

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
