Answer:

A = 314 inches^2

Step-by-step explanation:

We know the diameter of the glass.  We need to find the radius

d = 2r

20 = 2r

Divide each side by 2

20/2 = 2r/2

10 =r

To find the area of the glass

A = pi r^2

A = pi * 10^2

A = pi*100

A = 100 *(3.14)

   = 314 in^2

lemme turn upwards the prims a little, check the picture below.

notice the triangle has a base of 4 and a height of 3, and the prism is really just two triangles and 3 rectangles, so we can simply get the area of each figure and sum them up, and that's the area of the prism.

To compare the measures of variation for both weeks, calculate the range and standard deviation. Week 1 has a larger range and standard deviation compared to Week 2.

Explanation:

To compare and contrast the measures of variation for both weeks, we need to calculate the range and standard deviation for each week. The range is the difference between the highest and lowest values, while the standard deviation measures the average amount by which each data point differs from the mean.

For Week 1, the range is 90 (90 - 30), and the standard deviation is 25.62. For Week 2, the range is 30 (60 - 30), and the standard deviation is 11.55.

Therefore, Week 1 has a larger range and standard deviation compared to Week 2.

Answer:

Option A

V = 15h

Step-by-step explanation:

Given in the question some information regarding the heights and volume of the towers with rectangular blocks

Formula to use

30 =  Length x Width (2)

Length x Width   = 30/2

Length x Width   = 15

Formula best represents the heights of the blocks in terms of their volumes

V = 15h

Answer:

The correct answer is option A.  15h

Step-by-step explanation:

From the figure we can see that a table shows the relationship between heights and volume of rectangular blocks.

Heights          Volume

2                       15

3                       45

4                       60

10                    150

To find the formula in terms of heights

If height = 2 then volume = 30 = 2 * 15

If height = 3 then volume = 45 = 3 * 15

If height is 'h' then volume = 15 * h = 15h

____________________________________________________

Explanation for question A:

We are trying to found the amount of money he payed after 10 years.

He pays an annual (yearly) of $2,000, so we would just multiply 2,000 by 10, since we are trying to find the amount he point in 10 years, in which he pays $2,000 a year.

[tex]2000*10=20000[/tex]

Answer for Question A: Tim Tradesman paid $20,000 in premiums at the end of 10 years.

____________________________________________________

Explanation for question B:

In question B, we are trying to find the cash value of the policy at the end of 10 years.

To find the cash value at the end of 10 years, we would get the units of life insurance and multiply it by the cash value per unit

There would be 150 units of life insurance.

So we multiply:

[tex]150*89=13350[/tex]

Answer for Question B: The cash value of his policy will be $13,350 at the end of 10 years.

____________________________________________________

Explanation for question C:

In question C, we are trying to find the ratio of cash value to premiums paid.

Our cash value is 13,350 and we paid 20,000.

When you subtract 20,000 and 13,350, you would get 6,650.

[tex]20000-13350=6650[/tex]

Then when you add 20,000 and 13,350, you would get 33,350.

[tex]20000+13350=33350[/tex]

When you subtract 6,650 from 33,350, you would get 26,700

[tex]33350-6650=26700[/tex]

26,700 is 66.75% of 33,350.

Answer for Question c: The ratio as a percent for the cash value to premiums paid is 66.75%

Answer:

The statement which describes the ratio of weight to mass and the value of x is ⇒ 98/10 ; = 110 answer B

Step-by-step explanation:

* Lets explain how to solve the problem

- The mass (kilograms) values are

  20 , 50 , x , 130 , 140

- The corresponding weight (newtons) values are

  196 , 490 , 1078 , 1274 , 1372

* Lets find the ratio between weight to mass

∵ 196/20 ⇒ divide up and down by 2

∴ 196/20 = 98/10

∵ 490/50 ⇒ divide up and down by 10

∴ 49/5 ⇒ multiply up and down by 2

∴ 49/5 = 98/10

∴ 490/50 = 98/10

∵ 1274/130 ⇒ divide up and down by 13

∴ 1274/130 = 98/10

∵ 1372/140 ⇒ divide up and down by 14

∴ 1372/140 = 98/10

- All the ratios between weight to mass equal 98/10

∴ 1078/x = 98/10 ⇒ by using cross multiplication

∴ 98(x) = 1078(10)

∴ 98 x = 10780 ⇒ divide both sides by 98

∴ x = 110

* The statement which describes the ratio of weight to mass and the

  value of x is 98/10; = 110

The ratio of weight to mass is constant. Write the ratio of weight to mass in simplest form to represent the table.  Answer: 9.8

What should the value of x be in the table? Answer 110 kilograms

Answer:

Part a) The measurement of arc KL is [tex]20\°[/tex]

Part b) The measurement of arc MJ is [tex]80\°[/tex]

Step-by-step explanation:

Let

x--------> the measure of arc KL

y-------> the measure of arc MJ

we know that

The measurement of the outer angle is the semi-difference of the arcs it encompasses.

[tex]m<MEJ=\frac{1}{2}(y-x)[/tex]

substitute the given value

[tex]30\°=\frac{1}{2}(y-x)[/tex]

[tex]60\°=(y-x)[/tex]

[tex]y=60\°+x[/tex] ------> equation A

The measure of the inner angle is the semi-sum of the arcs comprising it and its opposite.

[tex]m<MFJ=\frac{1}{2}(x+y)[/tex]

substitute the given value

[tex]50\°=\frac{1}{2}(x+y)[/tex]

[tex]100\°=(x+y)[/tex]

[tex]y=100\°-x[/tex] ------> equation B

Equate the equation A and B and solve for x

[tex]60\°+x=100\°-x[/tex]

[tex]2x=100\°-60\°[/tex]

[tex]x=20\°[/tex]

Find the value of  y

[tex]y=100\°-20\°=80\°[/tex]

therefore

The measurement of arc KL is [tex]20\°[/tex]

The measurement of arc MJ is [tex]80\°[/tex]

ANSWER

The length of a Diameter is 3.714

EXPLANATION

The circumscribed triangle is shown in the attachment.

We use the cosine ratio to find the altitude of the isosceles triangle.

[tex] \cos(60 \degree) = \frac{altitude}{hypotenuse} [/tex]

[tex] \cos(60 \degree) = \frac{altitude}{8} [/tex]

Altitude =8cos(60°)

Altitude=4cm

Let the upper half of the altitude be y cm.

Then the radius of the circle is (y-4)cm

The upper radius meets the tangent at right angles.

From the smaller right triangle,

[tex] \sin(60 \degree) = \frac{4 - y}{y} [/tex]

[tex] y\sin(60 \degree) = 4 - y[/tex]

[tex]y\sin(60 \degree) + y= 4 [/tex]

[tex](\sin(60 \degree) + 1)y= 4 [/tex]

[tex]y= \frac{4}{\sin(60 \degree) + 1} [/tex]

[tex]y = 16 - 8 \sqrt{3} [/tex]

y=1.857

The diameter is 2y

[tex]d = 32 - 16 \sqrt{3} [/tex]

=2(1.875)

The length of a Diameter is 3.714

Answer:

Diameter of the circle is 16 cm.

Step-by-step explanation:

Given : The measure of a vertex angle of an isosceles triangle is 120° and the length of a leg is 8 cm.

To find : The length of a diameter of the circle circumscribed about this triangle?

Solution :

We construct a circle in which an ABC isosceles triangle is formed.

Refer the attached figure below.

The measure of a vertex angle of an isosceles triangle is 120° .

The length of a leg is 8 cm, AC=8 cm

Vertex angle is divided by the line touching the center of the circle.

So, [tex]\angle A=60^\circ[/tex] and line AD=radius of the circle

Applying property of isosceles triangle,

Now, ∠DAC=∠ACD=∠CDA=60°

AC=DC=8 cm

The radius of the circle is 8 cm.

The diameter of the circle is twice the radius.

Therefore, The diameter of the circle is d=2(8)=16 cm.

Answer:

Amplitude = 4; period = π; phase shift: x = -pie/2

Step-by-step explanation:

For a sine wave of the following type:

y = Asin(Bx + C) + D, we have that:

A represents the amplitude

C represents the phase shift

D represents the vertical shift

And the period is given by: [tex]\frac{2 \pi}{B}[/tex]

Therefore, considering: f(x) = −4 sin(2x + π) − 5, we know that sin(a + π) = -sin(a). Then:

f(x) = −4 sin(2x + π) − 5 = 4sin(2x)-5 = 4cos(2x - π/2) - 5

The amplitude equals 4

The period is T = π

The fase shift is: -π/2.

Therefore, the correct option is:

Amplitude = 4; period = π; phase shift: x = -pie/2

Answer:

Required ratio is 2:5.

Step-by-step explanation:

Given that number of female nurses = 250

Given that number of male nurses = 100

Now we need to find about what is the ratio of male nurses to female nurses.

So we just need to divide number of male nurses by the number of female nurses. That means divide 100 by 250. We get:

[tex]\frac{male}{female}=\frac{100}{250}[/tex]

[tex]\frac{male}{female}=\frac{10}{25}[/tex]

[tex]\frac{male}{female}=\frac{2}{5}[/tex]

Hence required ratio is 2:5.

Answer:

Multiply both sides by 12

12 × cos42° = x, hence

x ≈ 8.9 → (c)

Answer:

B

Step-by-step explanation:

To find the value [tex]F(-9)[/tex] of the polynomial function [tex]F(x)=-x^2-10x-2,[/tex] you have simply substitute [tex]x=-9[/tex] into the function expression (write -9 instead of x):

[tex]F(-9)=-(-9)^2-10\cdot(-9)-2\\ \\=-81+90-2\\ \\=7[/tex]

Final answer:

To find f(-9) in the given function, substitute -9 for x and evaluate by following the transformation rules.

Explanation:

We can rewrite a given function as y = f{-2(x+1)}. To find f(-9), we substitute -9 for x in the function.

This gives us f(-9) = f{-2(-9+1)}. Calculating further results in f(-9) = f{-2(-8)}.

Therefore, to find f(-9), we evaluate the function at x = -8, and the value depends on the specific function provided.
