Sandra would pay in dollars for the dress is 0.76 c

What is discount ?

discount. if telling in the simple sentence discount means something which u get at lower price by its original price

According to the question,

c×(1 - 5%) × (1 - 20%)

=c×(1 - 0.05) × (1 - .20)

=c × 0.95 × 0.8

=0.76 c

Hence, Sandra would pay in dollars for the dress is 0.76 c

Answer:

y = 3

Step-by-step explanation:

Take 2 points from the graph: (1,3) (-1,3)

Use those 2 points to find the slope and y-intercept.

Slope: 3 - 3 / - 1 - 1 => 0 / -2 => 0

Slope is 0.

The y-intercept is (0,3)

hence, the equation will be y = 3

Answer:

d) 27 times

Step-by-step explanation:

Let l,w, and h represent the length, width and height of the small box.

Therefore, 3l,3w, and 3h are the dimensions of the large box.

The volume of a rectangular prism, such as a box, is the product of its length, width and height

Volume of small box = l*w*h = lwh

Volume of large  box = 3l*3w*3h = 27lwh

So we can see that the volume of the large box is 27 times larger.

Answer:

Use the law of cosines to find c:

Use the low of sines to find one of the missing angles:

Find the missing angle:

Answer:

c ≈ 6.49

A ≈ 17.9°

B ≈ 67.1°

Step-by-step explanation:

To find the length of side c, use the Cosine rule.

Cosine rule

[tex]\sf c^2=a^2+b^2-2ab \cos C[/tex]

(where a, b and c are the sides and C is the angle opposite side c)

From inspection of the given triangle:

Substitute the given values into the formula and solve for c:

[tex]\implies \sf c^2=2^2+6^2-2(2)(6) \cos 95^{\circ}[/tex]

[tex]\implies \sf c^2=4+36-24 \cos 95^{\circ}[/tex]

[tex]\implies \sf c=\sqrt{40-24 \cos 95^{\circ}}[/tex]

[tex]\implies \sf c=6.49\:\:(2\:d.p.)[/tex]

To find angles A and B, use the Sine Rule.

Sine Rule

[tex]\sf \dfrac{\sin A}{a}=\dfrac{\sin B}{b}=\dfrac{\sin C}{c}[/tex]

(where A, B and C are the angles and a, b and c are the sides opposite the angles)

From inspection of the given triangle:

Substitute the given values into the formula:

[tex]\implies \sf \dfrac{\sin A}{2}=\dfrac{\sin B}{6}=\dfrac{\sin 95^{\circ}}{\sqrt{40-24 \cos 95^{\circ}}}[/tex]

Solving for A:

[tex]\implies \sf \dfrac{\sin A}{2}=\dfrac{\sin 95^{\circ}}{\sqrt{40-24 \cos 95^{\circ}}}[/tex]

[tex]\implies \sf A=\sin^{-1}\left(\dfrac{2\sin 95^{\circ}}{\sqrt{40-24 \cos 95^{\circ}}}\right)[/tex]

[tex]\implies \sf A=17.9^{\circ}\:\:(1\:d.p.)[/tex]

Solving for B:

[tex]\implies \sf \dfrac{\sin B}{6}=\dfrac{\sin 95^{\circ}}{\sqrt{40-24 \cos 95^{\circ}}}[/tex]

[tex]\implies \sf B=\sin^{-1}\left(\dfrac{6\sin 95^{\circ}}{\sqrt{40-24 \cos 95^{\circ}}}\right)[/tex]

[tex]\implies \sf B=67.1^{\circ}\:\:(1\:d.p.)[/tex]

Answer: Y=-5x+3

Step-by-step explanation:

first slope= 0 on the x axis so -2-3=-5

to get 3 you can do 4-1=3 or 7-4 or even 1-(-2)!

Correct answer: [tex]y = 3x -5[/tex]

You don't have to use the whole table in order to find equation. You can use just two points on the table to start.

In order to find the slope, the formula for that is: [tex]\frac{y_{2}-y_{1}}{x_{2} - x_{1}}[/tex]. So, we can start with points (1, -2) and (2, 1). Label (1, -2) as [tex]x_{1}[/tex] and [tex]y_{1}[/tex]; label (2, 1) as [tex]x_{2}[/tex] and [tex]y_{2}[/tex]. Now we can plug the numbers into the formula.

[tex]\frac{1-(-2)}{2 - 1}[/tex] → [tex]\frac{3}{1}[/tex] → [tex]3[/tex] is the slope.

To find the y-intercept, substitute (1, -2) into [tex]y = 3x + b[/tex].

[tex](-2) = 3(1) + b[/tex]

[tex]-2 = 3 + b[/tex]

[tex]-3[/tex]   [tex]-3[/tex]

________

[tex]b = -5[/tex] is the y-intercept.

Thus, the slope-intercept equation is [tex]y = 3x -5[/tex]. Hope this helps :) Let me know if you have any other questions related to this problem!

Step-by-step explanation:

125 grams is 0.125 kilograms, 0.125 < 0.2

Answer:

6⅓ ft²

Step-by-step explanation:

Area of the figure = area of a trapezoid

= ½(a + b)h

Where,

a = 11⅓ft = 34/3 ft

b = 34/3 + 15/2 = (68 + 45)/6 = 113/6 ft

h = 6 ft

Plug in the values

Area = ½(34/3 + 113/6)*6

= (34/3 + 113/6)*3

= (68 + 113)/3

= 181/3

= 6⅓ ft²

D. b = 3

Step-by-step explanation:

Given the following data;

Points on x-axis (x1, x2) = 10, 12

Points on y-axis (y1, y2) = 23, 27

First of all, we would determine the slope.

Mathematically, slope is given by the formula;

[tex] Slope = \frac{Change \; in \; y \; axis}{Change \; in \; x \; axis} [/tex]

[tex] Slope, m = \frac {y_{2} - y_{1}}{x_{2} - x_{1}} [/tex]

Substituting into the equation, we have;

[tex] Slope, m = \frac {27 - 23}{12 - 10} [/tex]

[tex] Slope, m = \frac {4}{2} [/tex]

Slope, m = 2

The equation of straight line is y = mx + b

Where;

m is the slope.

x and y are the points

b is the intercept.

To find the intercept, we would use the following formula;

y - y1 = m(x - x1)

Substituting into the formula, we have;

y - 23 = 2(x - 10)

y - 23 = 2x - 20

y = 2x - 20 + 23

y = 2x + 3 = mx + b

Therefore, intercept, b = 3
