Answer:

On the first hour she gathered 8 mushroons, on the second 15 mushroons and on the third she gathered 14 mushroons.

Step-by-step explanation:

Helen gathred a total of 37 mushroons in three hours. On the first hour she gathered "x" mushroons, on the second hour she gathered "x + 7" mushroons and on the third hour she gathered "x + 6". Therefore the sum of mushrrons she gathered on each hour should be equal to the total she gathered as shown below:

37 = x + (x+ 7) + (x + 6)

37 = 3*x + 13

3*x + 13 = 37

3*x = 37 - 13

3*x = 24

x = 24 / 3

x = 8

On the first hour she gathered 8 mushroons, on the second 15 mushroons and on the third she gathered 14 mushroons.

Answer:

Helen gathered

8 mushrooms in the first hour,

15 mushrooms in the second hour and

14  mushrooms in the third hour.

Answer:

£116.67

Step-by-step explanation:

Given;

Nar donated to 4 charities last year. She gave £175 to each of these charities.

The total amount Nar donated is;

Nar = 4 × £175 = £700

For Rana to donate the same amount equally among 6 charity, to determine the amount each charity would receive this year, we need to divide the total amount by the number of charities;

A = £700/6

A = £116.67

Answer:

- In a 3-D setting, straight line aa can be perpendicular or parallel to straight line cc.

- In a 2-D setting, straight line aa can only be parallel to straight line cc.

- W ustawieniu trójwymiarowym linia prosta aa może być prostopadła lub równoległa do linii prostej cc.

- W ustawieniu 2-D linia prosta aa może być równoległa do linii prostej cc.

Step-by-step explanation:

English Translation

Straight line aa and straight line bb are perpendicular to each other, as well as straight line bb and straight line cc are perpendicular to each other. Choose the correct completion of the sentence. Line aa is perpendicular / parallel to line cc.

Solution

If the frame of reference for the lines is in 3-D, then, it is the straight line aa can also be perpendicular to the straight line cc in the same vein as the x, y and z component lines are usually all perpendicular to one another. Note that straight line aa could also be parallel to straight line cc in a 3-D frame of reference.

But in a 2-D frame of reference, straight line aa can only be parallel to straight line cc. This is because the only directions that straight line bb can be perpendicular to, in a 2-D setting, are all in the same parallel direction.

In Polish/Po polsku

Jeśli układ odniesienia dla linii jest w 3-D, to jest to linia prosta aa może być również prostopadła do linii prostej cc w tej samej żyle, ponieważ linie składowe x, y i z są zwykle wszystkie prostopadłe do jednego inne. Należy zauważyć, że linia prosta aa może być również równoległa do linii prostej cc w trójwymiarowym układzie odniesienia.

Ale w dwuwymiarowym układzie odniesienia linia prosta aa może być tylko równoległa do linii prostej cc. Jest tak, ponieważ jedyne kierunki, w których prosta bb może być prostopadła, w ustawieniu 2-D, wszystkie są w tym samym kierunku równoległym.

Answer:

[tex]-\dfrac{1}{4}[/tex]

Step-by-step explanation:

Given two points (-9,-6) and (3,-9). The slope of the line through the points is determined by the formula:

[tex]Slope, m=\dfrac{y_2-y_1}{x_2-x_1} ,$ where (x_1,y_1)=(-9,-6), (x_2,y_2)=(3,-9)\\$Therefore:\\ m=\dfrac{-9-(-6)}{3-(-9)}\\=\dfrac{-9+6}{3+9}\\=\dfrac{-3}{12}\\\\m=-\dfrac{1}{4}\\[/tex]

The slope of the line through the points (-9,-6) and (3,-9) is [tex]-\dfrac{1}{4}[/tex]

Answer:

the slope of the line through the points (-9,-6) and (3,-9) is [tex]-\dfrac{1}{4}[/tex]

Step-by-step explanation:

Given that,

Points (x₁ , y₁) is (-9,-6) respectively and

( x₂ , y₂) is (3,-9) respectively.

The slope of the line through the points is determined by the formula:

[tex]Slope, m=\dfrac{y_2-y_1}{x_2-x_1}[/tex]

where x₁ = -9

y₁ = -6

x₂ = 3

y₂ = -9

Therefore:

[tex]\\ m=\dfrac{-9-(-6)}{3-(-9)}\\=\dfrac{-9+6}{3+9}\\=\dfrac{-3}{12}\\\\m=-\dfrac{1}{4}\\[/tex]

Therefore, the slope of the line through the points (-9,-6) and (3,-9) is [tex]-\dfrac{1}{4}[/tex]

Answer:

Mean= 15.8, Median= 14.

Step-by-step explanation:

To find the mean, we need to find the average. We will simply need to add up all of the values and divide by how many there are.

Therefore:

[tex]\frac{14 + 19 + 20 + 12 + 14}{5}[/tex]= 15.8 = Mean.

To find the median, you can arrange the numbers in increasing order and find the middle value. You can do this like so:

12, 14, 14, 19, 20

The number in the middle of 14.

Option A)   Inside the circle

Step-by-step explanation:

step 1

Find the radius of the circle

we know that

The radius is equal to the distance from the center to any point on the circle

the formula to calculate the distance between two points is equal to

[tex]d\sqrt{(y2-y1)^2+(x2-x1)^2 }[/tex]

we have

A(-5,-8),M(-1,-3)

substitute the values

[tex]r=\sqrt{(-3+8)^{2}+(-1+5)^{2}}[/tex]

[tex]r=\sqrt{(5)^{2}+(4)^{2}}[/tex]

[tex]r=\sqrt{41}\ units[/tex]

step 2

Find the distance from the center to point V

we know that

If the distance from the center to point V is equal to the radius, then the point V lie on the circle

If the distance from the center to point V is less than the radius, then the point V lie inside the circle

If the distance from the center to point V is greater than the radius, then the point V lie outside the circle

we have

A(-5,-8),V(-11,-6)

substitute in the formula

[tex]d=\sqrt{(-6+8)^{2}+(-11+5)^{2}}[/tex]

[tex]d=\sqrt{(2)^{2}+(-6)^{2}}[/tex]

[tex]d=\sqrt{40}\ units[/tex]

so

[tex]\sqrt{40}\ units< \sqrt{41}\ units[/tex]

The distance from the center to point V is less than the radius

therefore

The point V lie inside the circle

Answer:

The length of a training track running around the field is  [tex]Z = 377.54 \ m[/tex]

Step-by-step explanation:

From the question we are told that

      The length of the field is  [tex]L= 93 \ m[/tex]

       The width of the field is  [tex]W = 61 \ m[/tex]

The length of the two semicircle is mathematically evaluated as

          [tex]A = 2 * \pi * \frac{W}{2}[/tex]

substituting values

          [tex]A = 2 *3.142 * \frac{61}{2}[/tex]

         [tex]A = 191.54 \ m[/tex]

Now the length of a training track running around the field is

       [tex]Z = A + 2 L[/tex]

  substituting values

       [tex]Z = 191.54 + 2 (93)[/tex]

       [tex]Z = 377.54 \ m[/tex]

Step-by-step explanation:

Answer:

Think about a dice. When a dice is rolled there are 6 possible outcomes: 1, 2, 3, 4, 5 and 6. To find the probability of the event of rolling a 4, find the number of possible ways of rolling a 4 and divide it by the total number of possible outcomes.

There is one way of rolling a 4 and there are six possible outcomes, so the probability of rolling a 4 on a dice is . This is called the ‘theoretical probability’ - in theory, if you roll a dice six times then you should roll a 4 once.

Answer:

The cost of the carpet at Magic Carpet is: 90 + 9*(area of carpet)

The cost of carpet at Carpeteria is: 50 + 13*(area of carpet)

The algebraic expression for which the cost is the same is: 90 + 9*(area of carpet) = 50 + 13*(area of carpet)

The area of carpet for which the cost is the same is: 10 square yard

Step-by-step explanation:

6a) The cost for magic carpet:

This company charges a fixed fee and a price for each square yard of carpeting, therfore the expression for the cost is:

cost = 90 + 9*a

Where a is the area of carpet to be installed.

6)b) The cost for Capeteria:

This company also charges a fixed fee and a price for each square yard of carpeting, so the expression is:

cost = 50 + 13*a.

6) c) The algebraic expression for the cost to be the same in both stores:

90 + 9*a = 50 + 13*a

6) d) We need to solve the expression above for a:

50 + 13*a = 90 + 9*a

13*a - 9*a = 90 - 50

4*a = 40

a = 40/4 = 10

let's first convert this to number form.

3^6 / 3^3= what?

to divide a number with the same base but different exponent, we simply subtract the second exponent by the first exponent.

3^6 / 3^3 = 3^6-3=3^3

Answer:

12 hours

Step-by-step explanation:

First to solve this problem, let's look at what we are dealing with here. It says that Ali made $126 for 9 hours of work.

Let's set that up into a fraction so it's easier to look at.

money/time = 126/9

Now that we have that set up let's look at our other piece of information.

It asks for how many hours would Ali have to work in order to make $168 so let's figure that out.

In order to find out the number of hours, let's first find our unit rate which can be simply found by dividing our given money/time.

126/9 = 14.

This means that for every 1 hour, there will be 14 dollars earned.

Now that we know that, let's look for how many hours it take to earn $168.

In order to do that simply see how many times 14 goes into 168 (division) and that way you can see how many hours it will take to earn $168.

168/14 = 12 hours.
