First, you must find the total number of people. Add together 32, 54, 78, 112, and 96 to get 372. Next, add the number of diabetic patients with the number of patients with eye problems (54 + 112 = 166).

Your fraction is now 116/372. Simplify this to get your answer, 29/93 or 0.31.

Answer:

Third option.

Step-by-step explanation:

You need to cube both sides of the equation. Remember the Power of a power property:

[tex](a^m)^n=a^{mn[/tex]

[tex]\sqrt[3]{162x^cy^5}=3x^2y(\sqrt[3]{6y^d})\\\\(\sqrt[3]{162x^cy^5})^3=(3x^2y(\sqrt[3]{6y^d}))^3\\\\162x^cy^5=27x^6y^36y^d[/tex]

According to the Product of powers property:

[tex](a^m)(a^n)=a^{(m+n)[/tex]

Then. simplifying you get:

[tex]162x^cy^5=162x^6y^{(3+d)}[/tex]

Now you need to compare the exponents. You can observe that the exponent of "x" on the right side is 6,  then the exponent of "x" on the left side must be 6. Therefore:

[tex]c=6[/tex]

You can notice that the exponent of "y" on the left side is 5,  then the exponent of "x" on the left side must be 5 too. Therefore "d" is:

[tex]3+d=5\\d=5-3\\d=2[/tex]

Answer:

13 is your answer

Step-by-step explanation:

x - 8.1 = 5.3

  +8.1    +8.1         Add 8.1 to both sides

x     =     13.4

Which if you want the whole number i'd be 13, Because if your rounding the 3, 4 won't bump the 3 up any because 4 isn't greater than 5.

Hope my answer has helped you!

Answer:

x=13

Step-by-step explanation:

A quick rough estimate could be obtained by adding 8 to both sides:

x = 5.3 + 8, or x = 13 (approx.)

The exact solution is x = 8.1 + 5.3 = 13.4 (which rounds down to 13).

Answer: 200 x 10

Step-by-step explanation:

√400 x √100 = 40,000  

√40,000 = 200  

The solution is :  The required simplified form is 20 × 10.

In mathematics, multiplication is a method of finding the product of two or more numbers. It is one of the basic arithmetic operations, that we use in everyday life.

here, we have,

We are given to find the simplified form of the following radical expression :

E = √400x100

We will be using the following property of radicals :

√x = x^1/2

and, √a* b = √a * √b

Therefore, we have

√400 x √100

= √40,000  

now, we get,

√40,000

= √400 x √100

=√20² x √10²  

=20x10

=200

Thus, the required simplified form is 20 × 10.

Answer:

B.) 83.7758

Step-by-step explanation:

Answer:

83.75 cubic inches

Step-by-step explanation:

We are given the diameter of a cone 8 inches, and height 5 inches and we are to find the volume of this cone.

(diameter is 8 inches so radius will be 4 inch)

We know that the volume of a cone is given by:

Volume of cone = [tex] \pi r ^ 2 \frac { h } { 3 } [/tex]

Substituting the given values in the above formula:

Volume of cone = [tex] \pi \times 4 ^ 2 \times \frac { 5 } { 3 } [/tex] = 83.75 cubic inches

(diameter is 8 inches so radius will be 4 inches)

For this case we must solve the following linear equation:

[tex]- \frac {1} {4} x + 5 = \frac {3} {4}[/tex]

Subtracting 5 from both sides of the equation we have:

[tex]- \frac {1} {4} x = \frac {3} {4} -5\\- \frac {1} {4} x = \frac {3-20} {4}\\- \frac {1} {4} x = - \frac {17} {4}[/tex]

Multiplying by 4 on both sides of the equation:

[tex]-x = -17[/tex]

Multiplying by -1 on both sides of the equation we have:

[tex]x = 17[/tex]

Answer:

[tex]x = 17[/tex]

Answer: [tex]x=17[/tex]

Step-by-step explanation:

You need to solve for the variable "x":

The first step is to subtract 5 from both side of the equation, then:

[tex]-\frac{1}{4}x+5-5=\frac{3}{4}-5\\\\-\frac{1}{4}x=-\frac{17}{4}[/tex]

The final step is to multiply both sides of the equation by -4.

Therefore, the value of the variable "x" is the following:

[tex](-4)(-\frac{1}{4}x)=(-\frac{17}{4})(-4)\\\\x=17[/tex]

Step-by-step explanation:

The fact that all right angles can be bisected is not a postulate of Euclidean geometry.

Euclidean geometry is the classical form of geometry first described by Euclid in his work Elements. He gathered all the mathematical knowledge known to the Greeks at the time, today his work presents itself as the first known axiomatization in the history of mathematics.

Originally, it was only cultivated on a plane and in three-dimensional space, at the same time linking it with the physical world that it was supposed to describe, thus preventing the possibility of studying other varieties of geometry.

x = - 1

Step-by-step explanation:

2(x-3)²-32=0                      Add 32 to both sides

2(x-3)² - 32+32 = 32          Combine

2(x - 3)²  = 32                     Divide by 2

2(x - 3)² /2 = 32/2              Do the division

(x - 3)² = 16                         Take the square root of both sides

sqrt(x - 3)² = sqrt(16)           Do the square root.

x - 3 = +/- 4

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

x - 3 = 4                                Add 3 to both sides

x - 3+3 = 4+3

x = 7

The simplified formula for calculating the monthly lease payment for a car is the sum of the depreciation fee and the finance fee. These are calculated based on the car's initial cost, residual value, and the lease factor.

In the context of car leasing, the simplified formula used to calculate the monthly lease payment is: depreciation fee + finance fee. The depreciation fee is calculated by subtracting the car's expected residual value at the end of the lease from its initial cost (MSRP) and then dividing this by the number of months in the lease. The finance fee is calculated as the sum of the MSRP and the residual value, multiplied by the lease factor or money factor which is essentially the interest rate.

Answer:

[tex]f(x)=\frac{3}{5}(x+1)^2+4[/tex]

Step-by-step explanation:

The equation of a quadratic function in vertex form is given by:

[tex]f(x)=a(x-h)^2+k[/tex]

Where (h,k) is the vertex.

It was given in the question that the vertex of the parabola is (-1,4).

When we substitute the vertex into the formula we get:

[tex]f(x)=a(x+1)^2+4[/tex]

The parabola also passes through (4,19) hence it must satisfy its equation.

[tex]19=a(4+1)^2+4[/tex]

[tex]19-4=a(5)^2[/tex]

[tex]15=25a[/tex]

We divide both sides by 25 to get:

[tex]a=\frac{15}{25}= \frac{3}{5}[/tex]

Hence the quadratic function is:

[tex]f(x)=\frac{3}{5}(x+1)^2+4[/tex]

2. -69/21 - 91/21 = -160/21

3. -7 13/21

Answer:

D.

Step-by-step explanation:

To find this area, we can break it up into two rectangles, one with dimensions of 4x19 and another of 24x11. All we have to do is find the areas of both rectangles and add them together!

Since 4*19=76 and 11*24=264, we get D. 340 square units as our answer.

For this case we have that the area of the figure is given by the sum of the areas of two rectangles. The area of a rectangle is given by:

[tex]A = a * b[/tex]

Where:

a, b: They are the sides of the rectangle

[tex]A_ {1} = 24 * 11\\A_ {1} = 264[/tex]

On the other hand:

[tex]A_{2} = 4 * (4 + 11 + 4) = 4 * 19 = 76[/tex]

Thus, the total area is:

[tex]A_ {t} = 264 + 76\\A_ {t} = 340[/tex]

The total area is 340 square units

Answer:

D. Vertex (1, -25); intercepts x = -4, 6

Step-by-step explanation:

Vertex

x = -b/2a

x = - (-2)/2(1)

x = 2/2

x = 1

y = 1^2 - 2(1) - 24

y = 1 - 2 - 24

y = -25

Vertex (1, -25)

x-intercepts when y = 0

x^2 - 2x - 24 = 0

(x - 6)(x + 4) = 0

x - 6 = 0; x = 6

x + 4 = 0;x = -4

Answer

D. Vertex (1, -25); intercepts x = -4, 6

The x-intercepts of the parabola are [tex]\( x = -3 \) and \( x = 1 \)[/tex].

To find the x-intercepts of the parabola defined by the equation [tex]\( y = -3x^2 - 6x + 9 \)[/tex], we need to set y=0 and solve for x.

So, we have:

[tex]\[ -3x^2 - 6x + 9 = 0 \][/tex]

Now, let's solve this quadratic equation using the quadratic formula:

[tex]\[ x = \frac{-b \pm \sqrt{b^2 - 4ac}}{2a} \]where \( a = -3 \), \( b = -6 \), and \( c = 9 \).\[ x = \frac{-(-6) \pm \sqrt{(-6)^2 - 4(-3)(9)}}{2(-3)} \]\[ x = \frac{6 \pm \sqrt{36 + 108}}{-6} \]\[ x = \frac{6 \pm \sqrt{144}}{-6} \][/tex]

[tex]\[ x = \frac{6 \pm 12}{-6} \][/tex]

Now, we have two possible values for x:

1. When [tex]\( x = \frac{6 + 12}{-6} = \frac{18}{-6} = -3 \)[/tex]

2. When [tex]\( x = \frac{6 - 12}{-6} = \frac{-6}{-6} = 1 \)[/tex]

Answer:

1 solution

Step-by-step explanation:

This is a linear equation and has one solution

6x - 4 = x + 6 ( subtract x from both sides )

5x - 4 = 6 ( add 4 to both sides )

5x = 10 ( divide both sides by 5 )

x = 10 ← only 1 solution
