a sweater that originally cost $40 is on sale for 10 percent off. what is the amount of the discount?

Andrej [43]

The retail price is 100% of the cost, and when 10% is taken off, that is the new price of the sweater.
100%-10%=90%
Then you convert the percentage to decimal and multiply the decimal with the retail price.

90%=0.9
0.9(40)=36
The new price of the sweater is $36.

Help pls will give brainliest

Answer:

Step-by-step explanation:

area of triangle = 1/2 x c x d =cd/2

area of semicircle = 1/2 x π x r^2 = 1/2 x π x (a/2)^2 = 1/2 x π x a^2/4 =πa^2/8

area of shape = area of triangle + area of semicircle

PLEASE HELP BRAINLY - which option is correct?

LuckyWell [14K]

Answer:

$y > \frac{2x}{3} + 1$

Step-by-step explanation:

Given:

The graph in the attachment where the coordinates are (3,3) and (-3,-1)

Required:

Which inequality represent the graph

The first step is to determine the slope of the graph

$m = \frac{y_2 - y_1}{x_2 - x_1}$

Where m represents the slope, $(x_1, y_1) = (3,3)$ and $(x_2, y_2) = (-3,-1)$

$m = \frac{-1 - 3}{-3 - 3}$

$m = \frac{-4}{-6}$

Simplify to lowest term

$m = \frac{2}{3}$

Next is to determine the equation of the line using the slope formula

$m = \frac{y - y_1}{x - x_1}$ , $(x_1, y_1) = (3,3)$ and $m = \frac{2}{3}$

$\frac{2}{3} = \frac{y - 3}{x - 3}$

Cross multiply

$2 * (x - 3) = 3 * (y - 3)$

Open both brackets

$2 x - 6 = 3y -9$

Collect like terms

$2 x - 6 +9= 3y$

$2 x+3= 3y$

Divide through by 3

$\frac{2x}{3} + \frac{3}{3} = \frac{3y}{3}$

$\frac{2x}{3} + 1 = y$

Reorder

$y = \frac{2x}{3} + 1$

Next is to determine the inequality sign

The dotted lines on the graph shows that the inequality sign is either > or <
Since the shaded region is the upper part of the graph, then the > inequality sign will be considered,

The inequality becomes

$y > \frac{2x}{3} + 1$

Circle A is intersected by lines LM and MO. What is the measure of angle LMO?

dusya [7]

$\angle LMO = \frac{LO - LN}{2} = \frac{148^{\circ}-59^{\circ}}{2}=\frac{99^{\circ}}{2}=48.5^{\circ}$

Which pair of angles are vertical angles?

Vlad1618 [11]

ANSWER

$< \: WRS \: \:and \: < \: \: VRT$

EXPLANATION

Vertical angles face each other directly opposite just like the angles formed on the opposite sides of the letter X.

Vertical angles, also called vertically opposite angles are equal.

From the above diagram,
$< \: WRS= < \: VRT$

because they are vertically opposite to each other.

The correct answer is B.
