Answer:

26 hours + 6 minutes can also be said as 1560 min + 6 minutes

1560+6/6 = 1566/6 = 261

That is = 4 hours and 21 minutes

Answer:

AC =5

BC =  12

AB = 13

Step-by-step explanation:

Since this is a right triangle, we can use the Pythagorean theorem

a^2 + b^2 = c^2

(n-1)^2 + (2n)^2 = (n+7)^2

FOILing

n^2-2n+1  + 4n^2 = n^2+14n+49

Combine like terms

5n^2-2n+1   = n^2+14n+49

Bring everything to the left

5n^2-2n+1 -n^2-14n-49  = n^2+14n+49-n^2-14n-49

4n^2 -16n -48 = 0

Divide by 4

n^2 -4n -12 = 0

Factor

( n-6)(n+2) =0

Using the zero product property

n-6 =0  n+2 =0

n=6    n=-2

Since the length cannot be negative

n=6

AC = n-1 = 6-1 =5

BC = 2n = 2*6 = 12

AB = n+7 = 6+7 = 13

Given :

Hypotenuse of right angle triangle = n + 7

Base = n - 1

Altitude = 2n

Using Pythagoras theorem :

→ ( n + 7 )² = (n - 1)² + (2n)²

→ n² + 14n + 49 = n² - 2n + 1 + 4n²

→ n² + 14n + 49 = 5n² - 2n + 1 = 0

→ n² + 14n + 49 - 5n² + 2n - 1 = 0

→ -4n² + 16n + 48 = 0

→ -4(n² - 4n - 12) = 0

→ n² - 6n + 2n - 12 = 0

→ n(n - 6) + 2(n - 6) = 0

→ (n - 6)(n + 2) = 0

As n ≠ Negative

So, n ≠ -2

So, n = 6

Hypotenuse = n + 7 = 6 + 7 = 13

Base = n - 1 = 6 - 1 = 5

Altitude = 2n = 2 × 6 = 12

So,

AB = 13

AC = 5

BC = 12

Answer: Phelan now have 44.69 US dollars. of the original 250 US dollars.

Step-by-step explanation:

Given, Phelan spent 150 euros on his trip.

1 European euro = 1.3687 US dollars

So, 150 euros = 150 × 1.3687 US dollars

= 205.305 US dollars

≈ 205.31 US dollars [ Rounded to the nearest cent. ]

Initially he had 250 US dollars, now he has left (250-205.31)US dollars that is

44.69 US dollars.

Hence, Phelan now have 44.69 US dollars. of the original 250 US dollars.

Phelan now have 44.69 US dollars. of the original 250 US dollars.

Answer:

a translation is the movement of the shape from units left to right or up and down so its basically scooching over to the left for example but the size or shape doesn't change, hope this helped

Step-by-step explanation:

===============================================

Let a,b,c,d be scalars.

In general if v and w are two vectors such that

v = <a, b>

w = <c,d>

then the difference of the two vectors is

v - w = <a-c, b-d>

so we subtract the coordinates

-----------------

Using that idea for the given vectors leads to

v = <9, -1>

w = <-1, -6>

v - w = <9 - (-1), -1-(-6)>

v - w = <9+1, -1+6>

v - w = < 10, 5 >

Answer:

and independent variable It is a variable that stands alone and isn't changed by the other variables you are trying to measure. For example, someone's age might be an independent variable. and a Just like an independent variable, a dependent variable is exactly what it sounds like. It is something that depends on other factors. For example, a test score could be a dependent variable because it could change depending on several factors such as how much you studied, how much sleep you got the night before you took the test, or even how hungry you were when you took it.

C.

The solution to this is x ≤ 4.

So then we look at the graphs and choose the correct one.

When the sign is ≤ it's like an arrow whatever way it's pointing it goes that way. In this case it'd go the other way even though the sign is ≤, because the solution is stating 4 is greater then or equal to so it can't be less than 4. And the only option of +4 and higher is C.

Answer:

[tex]\large \boxed{\sf \frac{1}{9}}[/tex]

Step-by-step explanation:

[tex]\sf y=a(x-h)^2+k[/tex]

[tex]\sf Vertex = (h,k)[/tex]

y-value is 0 and the x value is 5

h = 2

k = -1

Solve for [tex]\sf a[/tex] (the coefficient of the squared term).

[tex]\sf 0=a(3)^2+-1[/tex]

The coefficient of the squared term in the parabola equation is 1/9.

Answer:

Fot this parabola the coefficient for squared term is 7

Step-by-step explanation:

The formula for vertex equation is:

x = a*(y-h)^{2}+kx=a∗(y−h)

2

+k

if vertex is at (-3,-1) and in the formula the vertex is (k,h), we replace this values

x = a*(y +1)^{2} -3x=a∗(y+1)

2

−3

The other point of this parabola is (4,0), so we replace it in the formula below:

4 = a*(0 + 1)^{2} -34=a∗(0+1)

2

−3

4 = a*(1)-34=a∗(1)−3

4 +3= a*(1)4+3=a∗(1)

a=7a=7

Answer:

The answer is c

Step-by-step explanation:

You have to do everything backwards,

-9 divide it by 3 to get -3, then add seven to that answer

Answer:

C

Step-by-step explanation:

You can work backward to find out the answer!

Start with -9. Instead of multiplying by 3, you can divide.

-9/3 = -3

Now, instead of decreasing -3 by 7, increase by 7.

-3+7 = 4

You get 4, which is C!

Answer:

I'm not sure but I believe it is "Three plus one-half times x."

Answer:

x + 6

Step-by-step explanation:

From the question given above, the following data were obtained:

Length of rectangle = 3x + 6

Width of rectangle = 4x – 1

Width of door =..?

A careful observation of the diagram shows that the door is located along the length of rectangular room.

In a rectangle, two sides are equal. Therefore,

x + door + x = 3x + 6

Making door subject of the above formula, we have:

x + door + x = 3x + 6

door + x + x = 3x + 6

door + 2x = 3x + 6

Subtract 2x from both side

door + 2x – 2x = 3x + 6 – 2x

door = 3x – 2x + 6

door = x + 6

Therefore, the width of the door is x + 6

Answer/Step-by-step explanation:

The scale factor = the ratio of the corresponding sides of the image and the preimage.

That is, A'B'/AB = B'C'/BC

The preimage is the smaller figure, given as ABCD.

AB = 3 - 1 = 2 units

BC = 4 - 1 = 3 units

The image is the larger figure, given as A'B'C'D'.

A'B' = 9 - 5 = 4 units

B'C' = 7 - 1 = 6 units

Scale factor = [tex] \frac{4}{2} = \frac{6}{3} = 2 [/tex]

Answer:

30

Step-by-step explanation:

The exterior angle of a triangle is equal to the sum of the opposite interior angles

150 = ?+120

Subtract 120 from each side

150-120 = ?

30 = ?

Answer:

[tex]\huge\boxed{<SUT = 30\ degrees}[/tex]

Step-by-step explanation:

According to exterior angle theorem:

The measure of the exterior angle is equal to the sum of non-adjacent interior angles.

So,

< VST = <STU + <SUT

150 = 120 + <SUT

<SUT = 150-120

<SUT = 30 degrees

2m is term because it is what you are looking for

In the expression 4(2m-n), (2m-n). is a term and  In expression 4(2m-n), 2m is also a term. The correct options are B and B for both.

One mathematical expression makes up a term. It could be a single variable (a letter), a single number (positive or negative), or the number of variables multiplied but never added or subtracted.

Variables in certain words have a number in front of them. A term is defined as a single number or single variable or number and variable multiplying with each other in a mathematics expression.

The first expression is 4(2m-n), then in the expression 2m - n will be the term of the expression.

The second expression is 4(2m-n), then in the expression 2m is the term of the expression.

Therefore, the expression 4(2m-n), (2m-n). is a term and  In expression 4(2m-n), 2m is also a term.

Answer: -6/7

Step-by-step explanation:

3(5f+2)-f=2(-3)
