Step-by-step explanation:

The student's question is unclear and lacks clarity. It is recommended that they provide more information or context so that an accurate explanation can be given.

The question seems to be unclear. As a tutor, I would ask the student to clarify their question more specifically. The number '400.902' is indeed an expression, however, it's not clear what it's supposed to be equivalent to. Understanding the context can help provide a more accurate answer, as '400.902' could represent a multitude of things, such as a decimal, a fraction, a percentage or even part of a scientific notation. Without this information, I can't provide a reliable explanation or comparison.

Answer: The center is 0,4

Step-by-step explanation:

Use this form to determine the center and radius of the circle:

(

x-h)^2+(y-k)^2=r^2

Match the values in this circle to those of the standard form. The variable  r  represents the radius of the circle,  h  represents the x-offset from the origin, and  k  represents the y-offset from origin:

r=8

h=0

k=4

The center of the cirle is found at (h,k): (0,4)

The radius is 8

Answer: 30%

Step-by-step explanation:

Subtract the original cost from the on sale price.

21.50 - 15.05 = 6.45

Divide the savings by the original cost.

6.45/21.50 = .3

Multiply by 100

.3 * 100 = 30

Answer:

30% percent

Step-by-step explanation:

21.50-15.05=6.45

21.50÷6.45=3.

3×100=30%

we times 100 because 1 equal 100%.So you need to do is just to multiply the number by 100 and add at the end symbol %

Answer:

- 30.75 < x < - 29.25

Step-by-step explanation:

Inequalities of the type | x | < a , always have solutions of the form

- a < x < a

Given

| 0.2x + 6 | < 0.15, then

- 0.15 < 0.2x + 6 < 0.15 ( subtract 6 from all 3 intervals )

- 6.15 < 0.2x < - 5.85 ( divide all intervals by 0.2 )

- 30.75 < x < - 29.25

To solve the inequality |0.2x+6| < 0.15, we split it into two separate inequalities and find that the solution for x is -30.75 < x < -29.25.

To solve the inequality |0.2x+6| < 0.15, we first consider the absolute value function. This means we are looking for values of x that make 0.2x + 6 less than 0.15 and greater than -0.15. We split this into two separate inequalities:

Solving the first inequality for x:

0.2x < 0.15 - 6
0.2x < -5.85
x < -5.85 / 0.2
x < -29.25

Solving the second inequality for x:

0.2x > -0.15 - 6
0.2x > -6.15
x > -6.15 / 0.2
x > -30.75

Therefore, combining the two inequalities, we find the solution for x is:

-30.75 < x < -29.25.

Answer: P(t) = 5000(1.02)^5

Step-by-step explanation:

The equation representing 'twenty less than the product of 3 and a number is -29' is 3n - 20 = -29. Solving for n, we find that n equals -3.

When solving the equation twenty less than the product of 3 and a number is -29, we can translate this into a mathematical expression as 3n - 20 = -29, where n represents the unknown number. To find the value of n, add 20 to both sides of the equation, which gives us 3n = -9. Dividing both sides by 3, we find that n = -3. Thus, the number we are looking for is -3.

[tex]116.5^{3}[/tex]

The approximate total volume of the silo is 116.9 m^3, the correct option is C. 116.5 m^3.

Suppose that the radius of considered right circular cylinder be 'r' units.

And let its height be 'h' units.

Then, its volume is given as:

[tex]V = \pi r^2 h \: \rm unit^3[/tex]

Right circular cylinder is the cylinder in which the line joining center of top circle of the cylinder to the center of the base circle of the cylinder is perpendicular to the surface of its base, and to the top.

We are given that;

Diameter=4.4m

Height=6.2meter

Now,

The radius of the silo is half of its diameter, which is 4.4/2 = 2.2 meters. So, plugging in the given values and using 3.14 for π, we get:

V = πr^2h + (2/3)πr^3

V = 3.14(2.2^2)(6.2) + (2/3)3.14(2.2^3)

V = 94.25 + 22.64

V = 116.89

Therefore, the volume of silo will be 116.5 m^3.

Answer: 25%

Step-by-step explanation:

Bc I’m smort boi

A randomly chosen quadrilateral has four right angles, has a probability that the quadrilateral also has four equal side lengths is 33%.

Probability is a measure of the likelihood of an event to occur.

Many events cannot be predicted with total certainty.

We can predict only the chance of an event to occur i.e. how likely they are to happen, using it.

Given is a Venn diagram,

In the Venn diagram, we can see that we have 9 elements, 6 of these belong to the set R, 3 of them belong to the set E, and 2 belong to both sets.

Now we want to find the probability that, if a figure has four right angles (belongs to R) it also has 4 equal side lengths (belongs to E).

So, given that an element belongs to R (6 elements there).

The probability that it also belongs to E,

2 out of these 6 elements belong to E, so the probability will be:

P = 2/6 = 1/3 = 0.33

To get this in percent form, we need to multiply it by 100%, we will get:

0.33x100% = 33%

The length of CD is 6 feet.

The length of DE is x feet.

We need to determine the proportion that solves the distance between D and E.

Proportion:

The proportion that solves the distance between D and E can be determined by the similar triangle property.

The oblique prism below has an isosceles right triangle base. An oblique right triangular prism is shown. The triangular bases have 2 sides with a length of x. The length of they hypotenuse is unknown. The distance from the 2 triangular bases is (x + 3). The vertical height of the prism is (x + 2). What expression represents the volume of the prism, in cubic units?

One-halfx3 + x2

One-halfx3 + Three-halves x2

x3 + x2

x3 + 3x2

My answer:

Given that:

The oblique prism below has an isosceles right triangle base and the length of the base is x

=> the area of the base: 1/2 *x*x = 1/2[tex]x^{2}[/tex]

The vertical height of the prism is (x + 2)

=> The volume of the oblique prism is:

V = the base area * the vertical height

<=> V = 1/2[tex]x^{2}[/tex] (x + 2)

<=> V = [tex]1/2 x^{3}[/tex] + [tex]x^{2}[/tex]

The height of the cup is 0.51 in.

The height of the cup is 4.59 in.

Step-by-step explanation:

The volume of the cylinder is [tex]\pi r^2 h[/tex]

Given that,

The volume of the cup is 14.4375 in³.

If the measuring cup has a radius of 3 in.

Then,

[tex]\pi r^2h=14.4375[/tex]

Plug r= 3 in.

[tex]\pi (3)^2h=14.4375[/tex]

[tex]\Rightarrow h=\frac{14.475}{9\pi }[/tex]

⇒h=0.51 in.

The height of the cup is 0.51 in.

If it has radius of 1 in.

Then,

[tex]\pi r^2h=14.4375[/tex]

Plug r= 1 in.

[tex]\pi (1)^2h=14.4375[/tex]

[tex]\Rightarrow h=\frac{14.475}{1\pi }[/tex]

⇒h=4.59 in.

The height of the cup is 4.59 in.

Answer:

X=16

Y=5

Step-by-step explanation:

For equilateral triangle, length of both sides are equal hence 18y-41=3x+1=49

Solving for x

Given that 3x+1=49

Rearranging like terms

3x=49-1=48

x=48/3=16 units

Solving for y

Considering that 18y-41=49

18y=49+41=90

y=90/18=5 units

The value of x = 16 and y = 5.

Given that [tex]\( \triangle ABC \)[/tex] is an equilateral triangle, all sides are equal. Therefore, we have:

[tex]\[ AB = BC = AC \][/tex]

Given the side lengths:

[tex]\( AB = 49 \)[/tex] meters

[tex]\( BC = 3x + 1 \)[/tex] meters

[tex]\( AC = 18y - 41 \)[/tex] meters

Since [tex]\( AB = BC \)[/tex]:

[tex]\[ 49 = 3x + 1 \][/tex]

Solve for [tex]\( x \)[/tex]:

[tex]\[ 49 - 1 = 3x \][/tex]

[tex]\[ 48 = 3x \][/tex]

[tex]\[ x = \frac{48}{3} \][/tex]

[tex]\[ x = 16 \][/tex]

Next, since [tex]\( AB = AC \)[/tex]:

[tex]\[ 49 = 18y - 41 \][/tex]

Solve for [tex]\( y \)[/tex]:

[tex]\[ 49 + 41 = 18y \][/tex]

[tex]\[ 90 = 18y \][/tex]

[tex]\[ y = \frac{90}{18} \][/tex]

[tex]\[ y = 5 \][/tex]

If ABC Is an equilateral triangle, solve for both x and y.
