We can calculate eee, the amount of euros that has the same value as ddd u.s. dollars, using the equation e= 17/20d how many euros have the same value as u.s. dollar? euros how many u.s. dollars have the same value as 1 euro?

Answers

0.85 euros have the same value as 1 U.S. dollar.

1.18 U.S. dollars have the same value as 1 euro.

What is Euro?

Euro (EUR) is used by 22 nations in Europe as their unit of exchange, including 17 members of the European Union.

What is Dollar?

The US dollar (USD) is the de facto currency for international trade and a reserve currency for the majority of the world. It is also the official currency of the US.

What is exchange rate of currencies?

A country's currency's value in relation to the currency of another country or economic region is known as the exchange rate.

Given equation : e = 17/20d

E = 17/20D
D = 1 dollar
Therefore:
E = 17/20 × 1
E = 0.85 euros

so, 0.85 euros have the same value as 1 U.S. dollar.

E = 17/20D
E = 1 euro
1 = 17/20D
D = 1 ÷ 17/20
D = 1 × 20/17
D = 1.1764705882 dollars
D = 1.18 dollars

so, 1.18 dollars have the same value as 1 euro.

if

[tex]2xy = 7[/tex]
find the value of
[tex] {x}^{2} + {y}^{2} + 6xy[/tex]

Answers

Answer:

32

Step-by-step explanation:

x²+y² = 11 equation--(i)

2xy = 7 equation--(ii)

Here,

= x²+y²+6xy

= 11 + 6xy (x²+y² = 11 from equation--(i))

= 11 + 3 × 2xy

= 11 + 3 × 7 (2xy = 7 from equation --(ii))

= 11 + 21

5/8 divided by 1/3 in simplest form

Answers

Answer: 1-7/8.

Step-by-step explanation;

Division of fractions is equivalent to multiplication by the reciprocal of the second fraction:  5/8 / 1/3 = 5/8 * 3/1.

Once rearranged, multiply all of the numerators by each other. Do the same with the denominators and form a new fraction with these values:  15/8.

15 ÷ 8 = 1R7, therefore:  1-7/8.

The required, 15/8, is the simplest form. It cannot be further reduced since the numerator (15) and the denominator (8) have no common factors other than 1.

To divide fractions, we multiply the first fraction by the reciprocal of the second fraction. The reciprocal of a fraction is obtained by swapping the numerator and denominator. Let's calculate the division:

(5/8) ÷ (1/3)

Find the reciprocal of the second fraction:

Reciprocal of (1/3) = 3/1 = 3

Now, multiply the first fraction by the reciprocal of the second fraction:

(5/8) * 3 = (5 * 3) / 8 = 15 / 8

So, the answer to 5/8 divided by 1/3 in simplest form is 15/8.

A number consists of two digits. The sum of its digits is 16. If 28 is subtracted from the number, the digits interchange their place. Find the number. |.Give the answer only ​

Answers

Answer:

The number is 97

Step-by-step explanation:

Note: The difference should read 18 not 28, it must be a typo. In general such difference must be a multiple of 9.  

Let the digits are x and y.

If the first digit is x and the second digit is y, then the number is 10x + y.

According to the question we have:

x + y = 1610x + y - 18 = 10y + x ⇒ 9x - 9y = 18  ⇒ x - y = 2

Add up the equations:

x + y + x - y = 16 + 22x = 18x = 9

Find y:

9 + y = 16y = 7

The number is 97.

A. y=-2/3x-4/3
B. y= - 2/3x-10/3
C. y= -2/3x-2/3
D. y= -2/3x -17/4

Answers

Answer:

B: y = -2/3x - 10/3

Step-by-step explanation:

The point is at (-2,-2), therefore when you input -2 into the desired equation, it should yield -2 as our output. If we use the equation B, the equation becomes

-4/3 - 10/3 which is -6/3. After dividing it we get -2 as the output.

To find the line yourself we use the point slope formula

y - y1 = m(x - x1)

The line is parallel to the one on the graph so the slope or m is equal to -2/3

We input the coordinates we want for y1 and x1.

y - (-2) = -2/3 (x - (-2))

y + 2 = -2/3x - 4/3

y + 6/3 = -2/3x - 4/3

y = -2/3x - 10/3

Y=-2/3x-10/3 so BBBBBBBBBBB

A pond contains 20 tadpoles, of which f are frog tadpoles and the others are toad tadpoles. If 10 more frog tadpoles are added to the pond, the probability of catching a frog tadpole is doubled. Find f

Answers

Answer:

The value of f is 5

Step-by-step explanation:

Initially, the number of frog tadpoles = f

The initial probability of catching a frog tadpole = f/20

Adding 10 more frog tadpoles,

Number of frog Tadpoles = f +10

Total number of tadpoles in the pond = 20+10 = 30

new probability of catching a frog tadpole = (f+10)/30

New probability of catching a frog tadpole = 2 x Initial probability of catching a frog tadpole

(f+10)/30 = 2 x (f/20)

(f+10)/30 = f/10

f+10 = f x 30/10

f+10 = 3f

2f = 10

f = 5

Which figure below does not illustrate rotational symmetry?

Answers

Answer:

the answer is F

Step-by-step explanation:

The correct option is option F , that is figure F shows the rotational symmetry.

What is rotational symmetry ?

An object's ability to maintain the same shape when rotated about its own axis is known as rotational symmetry.

Some figures are given and we have to tell which figure doesn't illustrate rotational symmetry.

Let's check them all , one by one.

F)

We know that rotational symmetry meant a figure looks the same when it is rotated. Here , if we consider a point on the circle and try to rotate it about its own axis , then we get to know that the figure does not looks same in all directions.

So , this figure doesn't have rotational symmetry.

G)

This figure is when rotated about its own axis , we get that that it looks same in all directions. This figure has rotational symmetry.

H)

This figure also has rotational symmetry.

G)

We know that a triangle follows the rotational symmetry. If we rotate it , we get the same looks in all directions. This figure has the rotational symmetry.

Therefore , the correct option is option F , that is figure F shows the rotational symmetry.
