a. The cost of each yoghurt to the nearest cent is 21,583 cents.

b. The cost of each yoghurt to the nearest rand is R216.

Given the following data:

a. To calculate the cost of each yoghurt to the nearest cent:

First of all, we would divide the total cost of a pack of six yoghurts by the total amount of yoghurts bought as follows:

[tex]A \;yoghurt = \frac{1295}{6}[/tex]

A yoghurt = R215.833.

Conversion:

1 Rand = 100 cents.

215.833 Rand = X cents.

Cross-multiplying, we have:

X = [tex]215.833 \times 100[/tex] = 21,583.3 cents.

A yoghurt ≈ 21,583 cents.

b. To calculate the cost of each yoghurt to the nearest rand:

A yoghurt = R215.833 ≈ R216.

Step-by-step explanation: divide it by 27x12 and the result should be close to 3 and because the 4th option is also close to 3, then that should be the correct answer.

Answer:

Step-by-step explanation:

Correct choice is B

Answer:

The Answer to the first one is x = 2. Here's an explanation so you can try and solve the others.

Step-by-step explanation:

First, y = x + 2. Meaning we can substitute the y in 2y. So, we get:

For the next equation:

Since both equations equal y, you must put them side by side.

With the 3rd one just substitute x in 3x with the equation it provides you with (y + 1) and solve (like in the first one).

Same thing with the last one (solve like the second one, side by side), since both equations equal y.

Hope this helps!!

Answer:

a = 2

Step-by-step explanation:

We know that the line of symmetry is equal to -b/2a. Since we know this, we can set up an equation by plugging in certain values.

The line of symmetry equals 2 and the line of symmetry equals -b/2a. By transitivity, 2 equals -b/2a.

In our equation, we are given what b is. b would be the second term in our quadratic equation, which is -8.

Now, we set up our equation and plug in known values.

2 = -b/2a

2 = [tex]-\frac{-8}{2a} [/tex]

Negatives cancel each other out:

2 = [tex]\frac{8}{2a} [/tex]

You can solve this part in many different ways, but I will do it using proportions:

[tex]\frac{2}{1} = \frac{8}{2a} [/tex]

2a *2 = 8 * 1

4a = 8

Divide by 4 on both sides

a = 2

Answer:

Answer:

maybe 129Step-by-step explanation:

Step-by-step explanation:

x = Moe's money

y = Loki's money

z = Nick's money

1/5 x = 1/4 y = 1/3 z (Moe gave 1/5, Loki 1/4, Nick 1/3, but all donations to Ott are the same amount of money).

that also means

y = 4/5 x

z = 3/5 x

in total the group has

x + 4/5 x + 3/5 x = 5/5 x + 4/5 x + 3/5 x = 12/5 x

Ott got 3× 1/5 x (since everybody gave the same amount of money, so it is in sum 3 times of what Moe gave).

so, Ott now has 3/5 x , out of a total of 12/5 x.

his fractional part is therefore

3/5 / 12/5 = 3/5 × 5/12 = 3/12 = 1/4.

he has 1/4 of the group's total money.

Answer:

Horizontal asymptote: y=0

Vertical asymptotes: x=-3, x=0, and x=2

Step-by-step explanation:

Hi there!

The asymptotes of a graph are lines that the graph travel infinitely closer to, but never touch.

For this graph, there is only one horizontal asymptote. This is the x-axis. Notice how the graph seems to be traveling closer and closer to it on both sides but it never seems to touch it.

y=0

Then, the vertical asymptotes are x=-3, x=0 (the y-axis) and x=2. Again, notice how these lines almost "split up" the graph.

Answer:

We are given two points (0,0) and (8,15)

15-0/8-0= 15/8 --> 8/15 for tangent

y=8/15(x) + b

plug in point A

y= 8/15 (x) +3.6

Check the picture below.

we know that the line AT is a tangent to the circle, so any radius line coming from the center of the circle will meet AT at the point of tangency, which is always a right-angle.

So we can say that line AT is perpendicular to line PA, as you see in the picture, line PA has a slope of 15/8, keeping in mind that perpendicular lines have negative reciprocal slopes then

[tex]\stackrel{\textit{perpendicular lines have \underline{negative reciprocal} slopes}} {\stackrel{slope}{\cfrac{15}{8}} ~\hfill \stackrel{reciprocal}{\cfrac{8}{15}} ~\hfill \stackrel{negative~reciprocal}{-\cfrac{8}{15}}}[/tex]

so we're really looking for the equation of a line with a slope of -8/15 and that passes through (8 , 15).

[tex](\stackrel{x_1}{8}~,~\stackrel{y_1}{15})\qquad\qquad \stackrel{slope}{m}\implies -\cfrac{8}{15} \\\\\\ \begin{array}{|c|ll} \cline{1-1} \textit{point-slope form}\\ \cline{1-1} \\ y-y_1=m(x-x_1) \\\\ \cline{1-1} \end{array}\implies y-\stackrel{y_1}{15}=\stackrel{m}{-\cfrac{8}{15}}(x-\stackrel{x_1}{8}) \\\\\\ y-15=-\cfrac{8}{15}x+\cfrac{64}{15}\implies y=-\cfrac{8}{15}x+\cfrac{64}{15}+15\implies y=-\cfrac{8}{15}x+\cfrac{289}{15}[/tex]

Answer:

13.89 inch

Step-by-step explanation:

area  = length x width

=> width = area/length = 108.35/7.8 = 13.89 inch

Answer:

Answer:

[tex]9 \times {10}^{3} [/tex]

Step-by-step explanation:

(2.7 × 10^6) ÷ (3 × 10^2)

= (2.7 ÷ 3) × (10^6 ÷ 10^2)

= 0.9 × 10^(6 - 2)

= 0.9 × 10^4

= 9 × 10^(-1 + 4)

= 9 × 10^3

Using proportions, it is found that 5449.62 QR is equal to HKD 315920​.

Hence, the rule of three is:

2000 QR - 157960 NC

x QR - 13.62 NC

Applying cross multiplication:

[tex]157960x = 200(13.62)[/tex]

[tex]x = \frac{200(13.62)}{157960}[/tex]

[tex]x = 0.01725[/tex]

Then:

Then, the second rule of three is:

1 HKD - 0.01725 QR

315920 HKD - x QR

Applying cross multiplication:

[tex]x = 0.01725(315920) = 5449.62[/tex]

5449.62 QR is equal to HKD 315920​.

Coterminal angles are those angles who both share same terminal sides.

Here. the Option C: 40°  + (360n)° for any whole number n is correct.

To find coterminal angle with a 400° angle.

Coterminal angles are those angles who both share same terminal sides.

Since terminal side can come at same place after one round forward, two round forward etc and one round backward, two round backward thus multiples of 360 or 0 can be added or subtracted.

A full round is of 360°.

If an angle is of [tex]\theta ^\circ[/tex], then [tex]\text{Coterminal angles of\:} \theta^\circ = \theta^\circ \pm 360^\circ n; n \in \mathbb Z[/tex]

Thus, we have:

Coterminal angles of 400 degrees = [tex]400 \pm 360n = 40+360 \pm 360n = 40 \pm 360(n+1); n+1 \in \mathbb Z\\or\\\text{Complementary angles of 400}^\circ = 40^\circ+360n^\circ; n \in \mathbb Z[/tex]

Thus, the Option C: 40°  + (360n)° for any integer n is correct.

Patrick was supposed to multiply 3 and 2 first and then do 8 - 6. (PEMDAS). So he made a mistake in the first step.

The step in which Patrick first made a mistake is Step 1.

Expression in mathematics is defined as the collection of numbers variables and functions by using signs like addition, subtraction, multiplication, and division.

We are given that;

The expression =7 x [8 - 3 x 2].

Now,

He did not follow the order of operations correctly. He should have multiplied 3 and 2 first, then subtracted that from 8, and then multiplied by 7.

The correct steps are:

7 x [8 - 3 x 2] Step 1: 7 x [8 - 6] Step 2: 7 x 2 Step 3: 14
