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.

Answer:

[tex]Probability = 0.504[/tex]

Step-by-step explanation:

Given

[tex]ID: 4\ digit\ number[/tex]

Required

Determine the probability that no two digit is repeated

First, we need to determine the total possible number of pins (with repetition)

Each of the 4 ID digit can be selected from any of the 10 digits (0 - 9).

i.e.

[tex]First = 10[/tex]

[tex]Second = 10[/tex]

[tex]Third = 10[/tex]

[tex]Fourth = 10[/tex]

[tex]Total = 10 * 10 * 10 * 10[/tex]

[tex]Total = 10000[/tex]

i.e.

[tex]n(Repetition) = 10000[/tex]

Next, we determine the total possible number of pins (without repetition)

Once a digit is selected from any of the 10 digits (0 - 9), it can no longer be repeated.

i.e.

[tex]First = 10[/tex]

[tex]Second = 10 - 1 = 9[/tex]

[tex]Third = 10 - 1 - 1= 8[/tex]

[tex]Fourth = 10 - 1 - 1 - 1 = 7[/tex]

[tex]Total = 10 * 9 * 8 * 7[/tex]

[tex]Total = 5040[/tex]

i.e.

[tex]n(No\ Repetition) = 5040[/tex]

The probability is then calculated as:

[tex]Probability = \frac{n(No\ Repetition)}{n(Repetition)}[/tex]

[tex]Probability = \frac{5040}{10000}[/tex]

[tex]Probability = 0.504[/tex]

Answer:

4

Step-by-step explanation:

Circumfrence is 2piR or piD, 20x3.14=62.8, 62.8/15.7=4

Answer:

4 flowers

Step-by-step explanation:

-Circumference of a circle formula: dπ (diameter times pi)

-So plug 3.14 for π and 20 for the diameter to solve it:

20(3.14)  which equals 62.8

-Do 62.8 divided by 15.7 to find how many flowers are around the edge (circumference):

62.8 ÷ 15.7, which equals 4

Answer: 4 flowers

Answer:

I think both are 75

Step-by-step explanation:

I know the bottom one is definitely 75.

For the top, if you substitute 75 for the y and 1 for the X, the only answer is 75. Please Mark Brainliest if correct.

Answer: X=6

Step-by-step explanation:    Rearrange the equation by subtracting what is to the right of the equal sign from both sides of the equation :

                    6-9*x-(7*x-10*x-30)=0  

Pulling out like terms

1.1     Pull out like factors :

  36 - 6x  =   -6 • (x - 6)  

This equation has no solution.

A a non-zero constant never equals zero.

Solving a Single Variable Equation:

2.2      Solve  :    x-6 = 0  

Add  6  to both sides of the equation :  

                     x = 6

Answer:

Answer:

x = 15

Step-by-step explanation:

The sum of the 3 angles in a triangle = 180°

Sum the 3 given angles and equate to 180, that is

3x - 10 + 6x + 5 + 4x - 10 = 180, simplify left side

13x - 15 = 180 ( add 15 to both sides )

13x = 195 ( divide both sides by 13 )

x = 15

Answer:

The area of the quadrilateral is 12 square feet. (B)

Step-by-step explanation:

To find the area of a triangle, we use the formula (L x W) / 2

The bottom triangles are both the same size, so we only need to find the area of one. The width of the triangle needs to be divided by two because we only need to know half of the big triangle on the bottom at the moment. So we have (3 x 2) / 2 = 3. We can then multiply that by two and the area of the bottom triangle is 6. To solve for the top, (3 x 4) / 2 = 6. We can then add together the top and the bottom to get B, 12 square feet.

Hope this helps!

Answer:

b = 0.4899

Step-by-step explanation:

Given;

2(2x-1)=5x²

4x - 2 = 5x²

5x² - 4x + 2 = 0

this is a quadratic equation with;

a = 5, b = -4 and c = 2

[tex]x = \frac{-b \ \ + /-\ \ \sqrt{b^2 - \ 4ac} }{2a} \\\\x = \frac{-(-4) \ \ + /-\ \ \sqrt{(-4)^2 - \ 4(5*2)} }{2(5)} \\\\x = \frac{4 \ \ + /-\ \ \sqrt{16 - \ 40} }{10} \\\\x = \frac{4 \ \ + /-\ \ \sqrt{-24} }{10}\\\\x = \frac{4 \ \ +/-\ \ (\sqrt{24)} (\sqrt{-1} ) }{10} \\\\x = \frac{4 \ \ +/-\ \ (\sqrt{24)} (i )}{10}\\\\ x = \frac{4 \ \ +/-\ \ (4.899) (i )}{10}\\\\ x = \frac{4 \ \ +\ \ (4.899) (i )}{10} \ \ or \ \ x = \frac{4 \ \ -\ \ (4.899) (i )}{10}\\\\[/tex]

in terms of a + bi, it will be simplified as;

[tex]x = \frac{4}{10} + \frac{(4.899) (i)}{10} \\\\x = 0.4 + 0.4899i[/tex]

Therefore, b = 0.4899

When the given expression is expressed in the simplest form of [tex]a+bi[/tex]  then the value of b is 0.4899.

Given-

The given expression in the problem is,

[tex]2(2x-1)=5x^2[/tex]

Simplify this,

[tex]4x-2=5x^2[/tex]

Arrange the above equation,

[tex]5x^2-4x+2=0[/tex]

Compare the above equation with general quadratic equation,

[tex]ax^2+bx+c=0[/tex]

we get,

[tex]a=5[/tex]

[tex]b=-4[/tex]

[tex]c=2[/tex]

Find the roots of the [tex]x[/tex] . The formula to find the roots of a quadratic equation can be given as,

[tex]x=\dfrac{-b\pm\sqrt{b^2-4ac} }{2a}[/tex]

[tex]x=\dfrac{-(-4)\pm\sqrt{(-4)^2-4\times5\times2} }{2\times 5}[/tex]

[tex]x=\dfrac{4\pm\sqrt{16-40} }{10}[/tex]

[tex]x=\dfrac{4\pm\sqrt{-24} }{10}[/tex]

[tex]x=\dfrac{4\pm\sqrt{-24}\sqrt{-1} }{10}[/tex]

[tex]x=\dfrac{4\pm 4.899i} {10}[/tex]

Take positive sign we get,

[tex]x=\dfrac{4+ 4.899i} {10}[/tex]

Take negative sign we get,

[tex]x=\dfrac{4-4.899i} {10}[/tex]

Compare the simplified form of  [tex]a+bi[/tex] with the root of [tex]x[/tex]

[tex]x=0.4+ 0.4899i[/tex]

here,

[tex]b=0.4899[/tex]

Hence when the given expression is expressed in the simplest form of [tex]a+bi[/tex]  then the value of b is 0.4899.

Answer: 1 1/6

Step-by-step explanation:

You are adding the fractions; they do not have the same denominator so you have to find a common denominator which is six. Multiply the numerator and denominator for the first fraction by 3 and multiply the numerator and denominator for the second fraction by 2. After that you are left with a denominator of six and a numerator of 3+4. You you solve 3+4 which equals 7. You then get 7/6 can you simplify that fractions 1 1/6.
