How much will it cost in Canadian dollars to purchase €2000 at a bank that charges a 2.2% commission on the transaction? Use an exchange rate of $1 Canadian equals €0.711142.

Answers

Answer:

$2,874.25 Canadian dollar

Step-by-step explanation:

The first thing to do here is to calculate the amount of the commission.

That would be 2.2% of €2,000

= 2.2/100 * €2,000 = €44

Now the total cost to pay = selling price + amount in commissions = €2,000 + €44 = €2,044

But we need our answer in the Canadian dollars

Mathematically;

$1 Canadian = €0.711142

$x Canadian = €2,044

x = (2,044 * 1)/0.711142

x = 2,874.25014975912

This is approximately $2,874.25 Canadian dollar

The mean is the average value which can be calculated by dividing the sum of observations by the number of observations

Mean = Sum of observations/the number of observations

It is Given that, there are 12 bags of apples on a market stall.  

The mean number of apples in each bag is 8.  

We need to calculate the number of apples in the 12 bags.

The mean of "n" observations is given as

Mean = Sum of observations/the number of observations

8 = sum of observations/12

The total number of apples = 8 x 12 = 96

Hence, there are 96 apples in 12 bags.

Step-by-step explanation:

The perimeter of the rectangle is 20 cm. One side is 6 cm long. What is the length of the missing side

Answers

Answer:

it is 4cm long

Step-by-step explanation:

You multiply 6 by 2 to get 12, then subtract 12 from 20 and get 8. Then you divide 8 by 2 to get 4. If you want to check it, you can add 6+6+4+4 to get 20

Answer: 4

Step-by-step explanation: the definition of a rectangle states that opposite sides of the rectangle are congruent. this means that there is 2 sides that measure 6cm. These two sides added together give us 12cm. By working backwards, we can subtract 12cm from the perimeter (20cm), this gives us 8cm. by diving that by 2 we can find the lenght of the missing sides, 4cm each.

what is the transitive property

Answers

Answer:

the transitive property of uniformity reveals to us that on the off chance that we have two things that are equivalent to one another and the subsequent thing is equivalent to a third thing, at that point the primary thing is additionally equivalent to the third thing. The recipe for this property is in the event that a = b and b = c, at that point a = c.

Step-by-step explanation:

Area 'A' is defined as the product of length and height

[tex]A=lh=300ft^2\\h= \frac{1}{3} l[/tex]

[tex]\\300=l( \frac{1}{3}l)\\300=\frac{1}{3} l^{2}\\900=l^{2}\\30=l\\l=30ft\\\\h= \frac{1}{3}(30)\\h=10ft[/tex]

6

Answers

Answer:

6 blue marbles

Step-by-step explanation:

Given;

Total number of marbles N = 15

probability of randomly selecting a green marble

P(G) = 1/5

The probability of randomly selecting a green marble, replacing it, and then randomly selecting a blue marble P(G∩B) = 2/25

P(G∩B) = P(G) × P(B)

P(B) = P(G∩B) ÷ P(G)

The probability of selecting a blue marble

P(B) = 2/25 ÷ 1/5 = 2/5

The number of blue marbles N(B) = P(B) × N

N(B) = 2/5 × 15 = 6

There are 6 blue marbles

Why does (-4 1/2)^2 = 20.25? Thank you please hurry!

Answers

Answer:

See below.

Step-by-step explanation:

Squaring a number means to multiply the number by itself.

For example, 3^2 means 3 * 3.

8^2 means 8 * 8.

(-6)^2 means (-6) * (-6).

In each case above, you see that the number that is squared is multiplied by itself.

In this case, (-4.5)^2, squaring the number -4.5, means multiply the number -4.5 by the number -4.5

(-4.5)^2 = (-4.5) * (-4.5)

Now we need to actually multiply -4.5 by -4.5

When you multiply a negative number by a negative number, the result is positive, so the product of -4.5 and -4.5 is a positive number. To find that number, you multiply 4.5 by 4.5

4.5 * 4.5 = 20.25

Therefore, (-4.5)^2 = 20.25

Using the properties of a kite, what is the measure of Angle X? 70° 90° 130° 140°

Answers

Answer:

70°

Step-by-step explanation:

Properties of a kite are:

a) They have two congruent sides

b) Their diagonal is perpendicular to each other.

c) On a kite, we also have two angles that are opposite and congruent to each other. These angles are the same

We would be using the property of a kite that says "On a kite, we also have two angles that are opposite and congruent to each other. These angles are the same" to solved this question.

In the diagram , the angles Z and X are opposite and congruent to one another. This means they are equal to each other.

Since angles Z= angle X

Let us call both of them angle a

Since a Kite is a Quadrilateral shape, the sum of angles in a Quadrilateral = 180°

Angle W = 90°

Angle Y = 130°

Angle X = a°

Angle Z = a°

Hence,

90° + 130° + a° + a° = 360°

220° + 2a° = 360°

2a° = 360° - 220°

2a° = 140°

a° = 140/2

a° = 70°

Therefore, from the calculation above, we can say that the measure of x = 70°

Answer:

70°

Step-by-step explanation:

Properties of a kite are:

a) They have two congruent sides

b) Their diagonal is perpendicular to each other.

c) On a kite, we also have two angles that are opposite and congruent to each other. These angles are the same

Moving from (-7, -9) to (-3, -4), x increases by 4 and y increases by 5.

Thus, the length of the hypotenuse / distance between the two points) is

The equation of a line in slope - intercept form is

c=m(n)+b

where

m is the slope

b is the c-intercept (value of c when the value of n is equal to zero)

Observing the graph  we have the points

Find the slope

The formula to calculate the slope between two points is equal to

m= c2-c1/n2-n1

substitute the values
