Answer:

24.44%

Step-by-step explanation:

1) Find the difference between 45 and 56 as a number.

2) Divide the result from Step 1 by the starting number 45.

3) Multiply the result from Step 2 by 100 to get it in terms of percent.

The three steps above can be made into a formula. Thus, to find the percent change from 45 to 56, we use this formula:

((Y-X)/X)*100 = Percent Change

X is the starting number 45, and Y is the ending number 56 that it changed to. When we enter these numbers into the formula, we get:

((56-45)/45)*100 = 24.44%

Thus, the answer to the question "What is the Percent Change from 45 to 56?" is:

Answer:

The answer is 12 hours.

If she completes 1/4 of a page in an hour completing one page will take her 4 hours after that you multiply it by 3 and get the total of 12 hours that is takes for her to do her homework

Answer:

the answer is 12 :)))))

Answer: 5 hours

Step-by-step explanation: because 50 multiply by 5 is 250 and more 75 for radiator

Step-by-step explanation:

Since X : Y = 1 : 2, X = 0.5Y.

Since Y : Z = 2 : 5, Z = 2.5Y.

We have X + Y + Z = 4Y = 40. Hence Y = 10.

[tex]y=10[/tex]

Given -

[tex]x+y+z=40\\x:y=1:2\\y:x=2:5[/tex]

To find - [tex]y[/tex]

Since,

[tex]x:y=1:2,x=0.5y\\y:x=2:5,z=2.5y\\x+y+z=4y+40\\y=10[/tex]

Therefore, [tex]y=10[/tex].

Answer:

18

Step-by-step explanation:

Area = base x height

So you would start by multiplying you 2 side lengths given:

Area = 2 sqrt 3 x sqrt 27

2 sqrt 3 x sqrt 27 = 18

Once multiplied, you will get you area. Which is 18 units squared.

Answer:

  31

Step-by-step explanation:

If we assume the number of potatoes is proportional to the weight, then we can write the equation ...

  n/10 = 10/3.2

  n = 100/3.2 = 31.25 . . . . . . . multiply by 10

There may be 31 potatoes in a 10-lb bag.

Answer: (x, y) = (10, 10)

Since x = y, replacing y with x in 6x - 3y = 30 we have 6x - 3x = 3x = 30, so x = 30/3 = 10. Then y = x = 10, so the solution is (10, 10).

Answer:

[tex]k = -\frac{1}{5}[/tex] -- Constant

[tex]y = -\frac{x}{5}[/tex] -- Equation

Step-by-step explanation:

Given

[tex]\{(-15, 3), (-5, 1), (0, 0), (10, -2)\}[/tex]

Solving (a): The constant of variation

The given parameter is of the form (x,y) and the variation constant is calculated using:

[tex]k = \frac{y}{x}[/tex]

For:(-15,3), k is calculated as

[tex]k = \frac{y}{x}[/tex]

[tex]k = \frac{3}{-15}[/tex]

[tex]k = -\frac{1}{5}[/tex]

For (-5,1)

[tex]k = \frac{y}{x}[/tex]

[tex]k = \frac{1}{-5}[/tex]

[tex]k = -\frac{1}{5}[/tex]

The equation is calculated using the following rule:

[tex]y = kx[/tex]

Substitute [tex]-\frac{1}{5}[/tex] for k

[tex]y = -\frac{1}{5} * x[/tex]

[tex]y = -\frac{x}{5}[/tex]

Answer:

48

Step-by-step explanation:

Vertical angles are congruent

7x - 22 = 4x + 8     {Add 22 to both sides}

         7x = 4x + 8 + 22

        7x = 4x + 30         { subtract 4x from both sides}

7x - 4x = 30

         3x = 30

           x = 30/3

x = 10

4x + 8 = 4*10 + 8

          = 40 + 8

          = 48

7x - 22 = 7*10 - 22

            = 70 - 22

            = 48

Answer:

First angle = 117 degrees.

Second angle = 63 degrees.

Answer:

she earns $10 per hour, and can earn $1 in 6 minutes (60 min divided by $10)

Step-by-step explanation:

Given:

A figure.

To find:

The values of x and y.

Solution:

We know that, in a right angled triangle,

[tex]\sin \theta =\dfrac{Perpendicular}{Hypotenuse}[/tex]

[tex]\sin 60^\circ =\dfrac{x}{16}[/tex]

[tex]\dfrac{\sqrt{3}}{2} =\dfrac{x}{16}[/tex]

Multiply both sides by 16.

[tex]\dfrac{\sqrt{3}}{2}\times 16=\dfrac{x}{16}\times 16[/tex]

[tex]8\sqrt{3}=x[/tex]

And,

[tex]\cos \theta =\dfrac{Base}{Hypotenuse}[/tex]

[tex]\cos 60^\circ =\dfrac{y}{16}[/tex]

[tex]\dfrac{1}{2}=\dfrac{y}{16}[/tex]

Multiply both sides by 16.

[tex]\dfrac{16}{2}=y[/tex]

[tex]8=y[/tex]

Therefore, the missing side lengths are [tex]x=8\sqrt{3}[/tex] and [tex]y=8[/tex].

Answer:

86 heartbeats per minute

Step-by-step explanation:

i assume that's your question?

the number of heartbeats per minute is 86.

The unitary method is a technique for solving a problem by first finding the value of a single unit, and then finding the necessary value by multiplying the single unit value.

Given that, 473 heartbeats in [tex]5\frac{1}{2}[/tex] = 11/2minutes

Number of heart beats per minute = Total number of heart beats ÷ Number of minutes

= 473÷ 11/2

= 473×2/11

= 43×2

= 86 beats per minute

Therefore, the number of heartbeats per minute is 86.
