Can someone help me? I dont really know how to do this?​

Answer:

Number of cinammon = 12

Number of chocolate = 21

Step-by-step explanation:

Given that:

Cost of Cinnamon candle , c = $3.50

Cost of chocolate candle , d = $2.50

Total amount raised, T = $94.50

d = 2c - 3

Total amount = (cost of Cinnamon * number sold) + (cost of chocolate * number sold)

94.50 = (3.50 * c) + (2.50 * (2c-3))

94.50 = 3.50c + 5c - 7.5

94.50 = 8.50c - 7.5

94.50 + 7.5 = 8.50c

102 = 8.50c

c = 102 / 8.50

c = 12

d = 2c - 3

d = 2(12) - 3

d = 24 - 3

d = 21

Answer:

5500

Step-by-step explanation:

5000 + (10 / 100) x 5000 = 5000 + (1/10) x 5000 = 5000 +500= 5500 people visted the book fair in the second week

Answer:

Total cost of polishing the floor is Rs/500.

Step-by-step explanation:

The floor consists of 2000 tiles which have the shape of a rhombus.

Area of rhombus = [tex]\frac{d_{1} *d_{2} }{2}[/tex]

Where: [tex]d_{1}[/tex] and [tex]d_{2}[/tex] are the diagonals.

Given that:

[tex]d_{1}[/tex] = 40 cm = 0.4 m

[tex]d_{2}[/tex] = 25 cm = 0.25 m

Then,

Area of each tile = [tex]\frac{0.4*0.25}{2}[/tex]

                     = [tex]\frac{0.1}{2}[/tex]

                     = 0.05 [tex]m^{2}[/tex]

Area of each tile is 0.05 [tex]m^{2}[/tex].

Since there are 2000 tiles on the floor of the building, then;

Total area covered by the tiles = 0.05 x 2000

                              = 100 [tex]m^{2}[/tex]

The total cost of polishing the floor = 100 x Rs/5

                                = Rs/500

Answer:

[tex]2\sqrt{5}+\sqrt{29}+\sqrt{53},\\\approx 17.14\:\mathrm{units}[/tex]

Step-by-step explanation:

The distance between two coordinates is given by:

[tex]d=\sqrt{(\Delta x)^2+(\Delta y)^2}[/tex], or [tex]d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}[/tex].

The distance between each of the coordinates of the triangle forms the sides of triangle. Therefore, we can add the distance between these coordinates to find the perimeter of the triangle.

The distance between [tex](3, -2)[/tex] and [tex](7, 0)[/tex] is:

[tex]d=\sqrt{(7-3)^2+(0-(-2))^2}=\sqrt{4^2+2^2}=\sqrt{20}=2\sqrt{5}[/tex]

The distance between [tex](3, -2)[/tex] and [tex](5, 5)[/tex] is:

[tex]d=\sqrt{(5-3)^2+(5-(-2))^2}=\sqrt{2^2+7^2}=\sqrt{53}}[/tex]

[tex]d=\sqrt{(7-5)^2+(0-5)^2}=\sqrt{2^2+5^2}=\sqrt{29}[/tex].

Therefore, the total perimeter of the triangle is:

[tex]\fbox{$2\sqrt{5}+\sqrt{29}+\sqrt{53}\:\checkmark$}[/tex].

Step-by-step explanation:

y = 5x - 4

When x = 0, y = 5(0) - 4 = -4.

When x = 1, y = 5(1) - 4 = 1.

When x = 2, y = 5(2) - 4 = 6.

The 3 ordered pairs we have are (0,-4), (1,1) and (2,6).

We now check the point (-5,-29):

(-29) : 5(-5) - 4

-29 : -25 - 4

-29 : -29 => -29 = -29.

Since Left hand side = Right hand side, the point (-5,-29) is a solution.

Answer:

1. (1,1) (2,6) (3, 11)

2. Yes

Step-by-step explanation:

1. 5(1)-4 = 5-4 = 1

5(2)-4 = 10-4 = 6

5(3)-4 = 15-4 = 11

(I just chose 3 simple x values and plugged them into the equation to get the y values then wrote it as an ordered pair)

2. 5(-5)-4 = -25-4 = -29

-29 = -29

(Same as number 1 but I used the given x value then I checked if the y value I got matched the ordered pair)

Answer:

The first one, As time increases, the number of Perennials sold has decreased

Step-by-step explanation:

Answer:

It's A or the first one on the top.

Step-by-step explanation:

Step-by-step explanation:

We know that

1m = 100cm

according to question

perimeter of rectangle = 2 (l+b)

22cm = 2 (100+b)cm

2×(100+b)cm = 22cm

100+b cm = 22/2cm

100+b cm = 11 cm

b = 100 -11 cm

Answer:

y=-3x+2

y = [tex]\frac{1}{5}[/tex]x - 5

Step-by-step explanation:

Question 1

It is given that;

- one of the lines has an equation of; y = -3x-7

- the given line's y-int is (0, 2) ~(The y-int is when the line crosses the y axis, hence x is zero)

- these two lines are parallel

When two lines are parallel, their slope is the same, hence  the equations of the given line would look like this;

y = -3x + 2

In the slope-intercept format (which is; y = mx + b, where "m" is the slope, and "b" is the y-intercept).

Questions 2

It is given that;

- one of the lines has an equation of y = -5x + 1

- the given line's y-int is (0, -5) ~(The y-int is when the line crosses the y axis, hence x is zero)

- these two lines are perpendicular

When two lines are perpendicular, their slopes are the negatives reciprocal of each other, hence the equations of the given line would look like this;

y = [tex]\frac{1}{5}[/tex]x - 5

In the slope-intercept format (which is; y = mx + b, where "m" is the slope, and "b" is the y-intercept).
