Answer:

D: 2f+15

Step-by-step explanation:

f is the number of stamps from France that Carlotta owns.

Twice this amount is 2f

Then, 15 more than twice this amount is 2f + 15, and this is the expression that represents the number of American stamps that Carlotta owns

Answer:

25^2=625

24^2= 576

7^2= 49

as 625 = 576+49 so 7,24,25 form a Pythagorean triplet

similarly

9,40,41 also is a Pythagorean triplet

Answer:

M=2

Step-by-step explanation:

m=2 Make sure to move the terms, then collect the like terms, then subtract, then divide both sides by 6

Answer:

m = 2.

Step-by-step explanation:

-7 + 4m + 10 = 15 - 2m

4m + 2m = 15 + 7 - 10

Answer:

The perimeter of rectangle ABCD = 16 units

Step-by-step explanation:

The vertices of the rectangle: A(−2,1), B(3, 1), C(3,4), and D(−2,4).

AB is horizontal, so measre the difference between the x coordinates of A and B.

between -2 and 3 are 5 units.

BC is vertical, so measre the difference between the y coordinates of B and C.

between 4 and 1 is 3 units.

The perimeter = 2 * ( AB + BC )

Substitute AB = 5 and CD = 3

2 * ( 5 + 3 )

2 * 8

The perimeter of rectangle ABCD = 16 units

Answer:

16 units

Step-by-step explanation:

finding the lengths of all sides which are 5,5,3, and 3 then adding them will get you 16 units.

negative three pi plus 4   BRAINLIEST :)

Answer:

[tex]\left(4-3\pi \right)^2 \text{ is a perfect square trinomial}[/tex]

[tex]\left(4-3\pi \right)^2=16-24\pi +9\pi ^2[/tex]

[tex]\sqrt{16-24\pi +9\pi ^2}\approx 5.42[/tex]

[tex]\sqrt{(4 -3\pi )^2} = -4 + 3\pi[/tex]

[tex]\sqrt{(4-3\pi )^2} = |4-3\pi|[/tex]

State that this is wrong, it cannot be negative

[tex]\sqrt{(4 -3\pi )^2} = 4 - 3\pi[/tex]

So,

[tex]\sqrt{(4 -3\pi )^2} \neq 4 - 3\pi[/tex]

State that [tex]\sqrt{a^2}=|a|[/tex]

It is [tex]a[/tex] assuming that a > 0

Answer:

y=45

x=90

Step-by-step explanation:

x is a right angle, y is vertical from 45 degrees making it congruent to it.

Answer:

C: x=90 y=45

Step-by-step explanation:

The place where x is is obviously a right angle therefore, it is 90. Then here is a diagonal line cutting through the 90 degrees in half. 90/2=45.

Answer:

1 1/2 hours

Step-by-step explanation:

19m = 1/2h

57m = xh

19 = 1/2

57 = x

19x = 1/2 (57)

19x = 28.5

÷19. ÷19

x = 1 1/2

Answer:  72

Step-by-step explanation:    so you do a line = line method the lines should look like they are fractions.  

you do it for the both numbers the percent is always out of 100.

it should look like this

40%            ?

--------- = -----------    

100%       180

then you cross multiply 40 and 180 and than divide it by 100.   your answer should be 72.    you later replace the ? with 72

you know this because It is smaller than 180 and its bigger than the number 40.

The number pages left to read is 12 pages.

Given that, George still has 40 percent of his book to read.

Percentage is defined as a given part or amount in every hundred. It is a fraction with 100 as the denominator and is represented by the symbol "%".

Let the total number of pages be x.

Now, x-40% of x=180

⇒ x-0.4x=180

⇒ 0.6x=180

⇒ x=180/0.6

⇒ x=300

So, remaining pages = 300-180=120

Therefore, the number pages left to read is 12 pages.

Answer:

A. y = 3sin(x-2) + 1

Step-by-step explanation:

The function whose graph is y= 3 sin (x-2)+1.

In mathematics, a function is an expression, rule, or law that establishes the relationship between an independent variable and a dependent variable. In mathematics, functions exist everywhere, and they are crucial for constructing physical links in the sciences.

As, From the graph that is provided to us we observe that,

when x=2 then f(x)=1.

1. y= 3 sin (x-2)+1

When x=2 gives y= 1

So, the equation satisfied.

2. y = 3 sin (x-2)+2

When x= 2 gives y= 2

So, the equation not satisfied.

3. y = 3 cos (x-2)+1

When x= 2 gives y > 1

So, the equation not satisfied.

Thus, the required function is y= 3 sin (x-2)+1.

Answer:

x = 5

y = 3

Step-by-step explanation:

9x and 45 are alternate interior angles, meaning they're congruent, so set them equal to one another, like so:

9x = 45

Divide both sides by 9:

x = 5

Solving for y, the two sides are of equal length, so set them equal:

6y = 18

Divide both sides by 6:

y = 3

Step-by-step explanation:

By alternate interior angle

9x=45°

x=5°

All parallel sides are equal in parallelogram

6y=18

y=3
