Answer: Nova Scotia

Step-by-step explanation:

British Columbia people per police officer:

= Population number / no. Of policemen

= 3,282,000/6,149

= 534 people per policeman

Nova Scotia

= 900,000 / 1,542

= 584 people per policeman

Answer:

1728

Step-by-step explanation:

1200 borrowed for 2 years at 20% compounded annually ;

Using the compound interest formula :

A = P(1 + r/n)^nt

P = 1200 = principal

Time, t = 2 years

Rate, r = 20% = 0.2

A = 1200(1 + 0.2)^2

A = 1200(1.2)^2

A = 1200 * 1.44

A = 1728

Final amount to be repayed = 1728

Step-by-step explanation:

The given recipe makes 8 bags.

To make 16 bags, Lily needs twice as many ingredients because 8 + 8 = 16.

Since 1 cup of raisins makes 8 bags, 2 cups of raisins will make 16 bags.

To show the mathematical way:

Variable w = number of cups of raisins

1/8 = w/16

Cross multiply

1 × 16 = 8 × w

16 = 8w

2 = w

2 cups of pretzels makes 8 bags so 6 cups of preztels will make how many bags?

Set up an equation:

Variable x = number of bags

2/8 = 6/x

Cross multiply

2 × x = 8 × 6

2x = 48

x = 24

6 cups of pretzels will make 24 bags.

If 0.5 cup of pecans = 2.5 cups of crackers, then 1 cup of pecans = y cups of crackers?

Variable y = number of cups of crackers

Set up equation:

0.5/2.5 = 1/y

Cross multiply

0.5 × y = 2.5 × 1

0.5y = 2.5

y = 5

1 cup of pecans will need 5 cups of crackers

2 cups of pretzels = 8 bags, so 1 cup of preztels = z bags?

Variable z = number of bags

Set up equation:

2/8 = 1/z

Cross multiply

2 × z = 8 × 1

2z = 8

z = 4

Answer: D

Step-by-step explanation: get the variable by itself on one side of the inequality sign.

Get the variable by itself on one side of the inequality sign. Option D

Isolating a variable in an equation or inequality refers to changing it so that it is on its own on one side of the equation or inequality sign.

In order to remove any additional terms or factors that are affecting the variable, this entails applying different operations to both sides of the equation or inequality, such as addition, subtraction, multiplication, or division.

The objective is to make the inequality or equation simpler so that the variable can be solved more easily.

Answer:

Step-by-step explanation:

the area of a parallelogram is the same as a rectangle, well, uses the same formula. therefore it uses base × height.

for this equation we need to do 7.1 × 11.4

7.1 × 11.4 = 80.94

if you need to round the number to a whole number, it will be 81 because the first decimal digit is the number 9, and any decimal number 5 or up rounds up to the next number :D

Answer:

Two things we need to remember:

Speed of light = c = 299,792,458 m / s

This means that the light in one second covers a distance of 299,792,458 m

And for a circle of radius R, the is:

C = 2*pi*R

where:

pi = 3.14

Then if the radius of the earth is 6,378.1 km, then the of the earth is:

C = 2*(3.14)*6,378.1 km = 40,054.468 km

And we know that 1 km = 1000m

Then the circumference of the earth is:

C = (40,054.468*1000) m = 40,054,468 m

Now we need to see how many times the light can encircle the earth per second. (we assume that the light can move in a circular path, this is not really accurate to the reality)

We know that in one second the light can cover a distance of:  299,792,458 m

And the circumference of the earth is: 40,054,468 m

The quotient between these two distances is the number of times that the light can encircle the earth:

N = (299,792,458 m)/(40,054,468 m)  = 7.5

So light could encircle the earth 7.5 times per second.

Given:

Speed to train = 200km/h

The train sets off from Station A at 12:24.

Reaches station B at 14:12.

To find:

The distance between both stations.

Solution:

We have,

Speed to train = 200km/h

Time taken by the train to cover the distance between station A and station B is the difference between 14:12 and 12:24.

Time = 1 hr 48 min

Time = 1.8 hours            [ 1 hr = 60 minutes]

Let d be the distance between both stations.

We know that,

[tex]Speed=\dfrac{Distance}{Time}[/tex]

[tex]200=\dfrac{d}{1.8}[/tex]

[tex]200\times 1.8=d[/tex]

[tex]360=d[/tex]

Therefore, the distance between the two stations is 360 km.

A number is written in scientific notation when there is a number greater than or equal to 1 but less than 10 multiplied by a power of 10.

If we have a number greater than 10, we move the decimal point to the left until we have a number between 1 and 10. ...

Answer:

the missing value is 18.

Step-by-step explanation:

First i converted the percentage to a fraction which was 30% was 3/10 or 0.3 or 3 and 100% was 1 so i took those numbers with 54, 1, 3, and Solve for an unknown value x with this fractions calculator. Find the missing fraction variable in the proportion using cross multiplication to calculate the unknown variable x. Solve the proportion between 2 fractions and calculate the missing fraction variable in equal's.

For the equation

543=x1

The cross product is

54×1=3×x

Solving for x

x=54×13

and reducing

x=18

Solution by Proportion

Since the equation is an equality

If

3 ÷ 1 = 3

Then it is true that

54 ÷ x = 3

Solving for x

x = 54 ÷ 3

x = 18

Answer:

1) 13 ft.

2) 23.3 m (when rounded to 1 dp)

Step-by-step explanation:

The Pythagorean theorem states that [tex]a^2+b^2=c^2[/tex] when a and b are the two legs (the sides adjacent to the right angle) and c is the hypotenuse (the longest side). This only applies to right triangles.

1) Question 1

The lengths of the two legs in the image are 12 ft. and 5 ft. We know that these are the legs because they are the sides adjacent to the right angle. We're solving for the length of the ladder, which in this case would represent the hypotenuse (c). Plug the values 12 and 15 into the equation as a and b and solve for c:

[tex]a^2+b^2=c^2\\12^2+5^2=c^2\\144+25=c^2\\144+25=c^2\\169=c^2[/tex]

Take the square root of both sides

[tex]\sqrt{169}=\sqrt{c^2} \\13=c[/tex]

Therefore, the length of the ladder is 13 ft.

2) Question 2

The lengths of the legs in the image are 20 m and 12 m. Again, we know that these are the legs because they are the sides adjacent to the right angle, which in this case would be the corner of the garden. We're solving for the length of the fence going diagonally from one corner to the other, which represents the hypotenuse (c). Plug the values 20 and 12 into the equation as a and b and solve for c:

[tex]20^2+12^2=c^2\\400+144=c^2\\544=c^2[/tex]

Take the square root of both sides

[tex]\sqrt{544}=\sqrt{c^2} \\23.3=c[/tex]

Therefore, the length of the fence when rounded to 1 decimal point is 23.3 m.

I hope this helps!

Step-by-step explanation:

Step-by-step explanation:

Plug in each given value into the expression to see if it is true.

Set given: {2 , 3  , 4}

Equation given: x + 2 = 6

First, plug in 2 for x. When x = 2:

x + 2 = 6

(2) + 2 = 6

4 ≠ 6.

Next, plug in 3 for x. When x = 3:

x + 2 = 6

(3) + 2 =6

5 ≠ 6.

Finally, plug in 4 for x. When x = 4:

x + 2 = 6

(4) + 2 = 6

6 = 6 (True).

In the given set, only 4 complete the equation.

Answer:

69090840 possible rankings

Step-by-step explanation:

The number of possible ranking ordered in terms of effectiveness can be obtained using permutation

Number of salesperson = 39

Number of rank = 5

nPr = n! ÷ (n - r)!

nPr = 39P5

39P5 = 39! ÷ (39 - 5)!

39P5 = 39! ÷ 34!

39P5 = 39 * 38 * 37 * 36 * 35 = 69090840

Step-by-step explanation:

First, we need to get rid of the integers:

4x = 22-6

Now, we solve that part:

4x = 16

If 4x is 16, then what is x? To solve this, we divide each side of the equation by 4:

1809 in.2.

Step-by-step explanation:

So we know that the formula of a circle's area is r^2 * pi.

In this case, the radius is 24 inches. 24^2 = 576. They tell us to use 3.14 for pi.

576 * 3.14 = 1808.64.

The area is 1808.64, which rounds up to 1809 in.2.
