The decimal 0.16 can be expressed as the fraction x/25. What is the value of x ?

Answer:

26

Step-by-step explanation:

The number has to be greater than 15 but not less than 25 so any number that is at least 25 works.

Answer:

It would just be at least 26. Because, it's saying that n has to be greater than 15 and greater than 25. so, that the n < 25 is wrong. So i would put 26 because 15 < (is less than) 26, and 26 <(less than) 25 is wrong which is required to be an answer. So you could do 26 through infinity.

Option 2 is the correct graph for the function f(x) = \(4[(1/2)^{x}]\) .

Given ,

f(x) = \(4[(1/2)^{x}]\)

Mathematically the graph will of exponential in nature.

So,

Let us assume few values to understand the nature of graph.

Firstly,

Let x= 1

f(x) = \(4[(1/2)^{1}]\)

f(x) = 2

Let x = 2

f(x) = \(4[(1/2)^{2}]\)

f(x) = 1

Let x = 3

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

f(x) = 0.5

Thus from these values of f(x) corresponding to the values of x second graph will be correct .

1)The number of milk chocolate that sold last week is = \(25\frac{2}{3}\) B is correct

2)white chocolate at the candy store last week is 19.

Last week, a candy store sold \(5\frac{1}{3}=\frac{16}{3}\) pounds of white chocolate. It sold 4 times as much milk chocolate as white chocolate.

The number of milk chocolate did the candy store sell last week.

Since the candy store sold 4 times as much milk chocolate as white chocolate, it sold:

\(4 *\frac{ 19}{3 } =\frac{ 76}{3}\\ pounds\ of\ milk\ chocolate.= 25 \frac{2}{3}\)

option B is correct.

2)

To find out how many more pounds of milk chocolate were sold than white chocolate at the candy store last week, we can subtract the amount of white chocolate sold from the amount of milk chocolate sold:

\(\frac{76}{3} - \frac{19}{3} \\= \frac{57}{3}\\ = 19\ pounds.\)

Answer:

5216.844

Step-by-step explanation:

Let x be the fourth number.

We know that the sum of the four numbers is 20500:

2341.578 + 10690 + x + 2341.578 = 20500

Simplifying and solving for x:

x = 20500 - 2341.578 - 10690 - 2341.578

x = 5216.844

The only graph that represents a function is: Graph D

A function is defined as a relationship or expression that involves one or more variables. It typically has a set of input and outputs.  Each input has only one output. The function is the description of how the inputs relate to the output.

A function is a relation which describes that there should be only one output for each input (or) we can say that a special kind of relation (a set of ordered pairs), which follows a rule i.e., every X-value should be associated with only one y-value is called a function.

From the graphs, we can see that:

Graph A has 2 outputs at x = -2

Graph B has 2 outputs at x = 0

Graph C has two outputs at x = -1

Graph D has a unique output for every input and as such it is a function

Answer:

Step-by-step explanation:

it would be "c" because the question asks for the number that makes the inequality true

4x≤ x+3

the graph in c is saying that every number that is 1 or less than 1 makes the inequality true. so lets take -7 as an example

4 x -7=-28

-28+3=-25

-25 is greater than -28 so the inequality is true. the reason why graph d doesnt work is because if we plug in 2 into the equation, then 4x =8 and x+3=5

5 is not greater than 8 so it doesnt work

Given statement solution is :- If the expression is set equal to 10x + 5, then there would be one solution.

If the expression is set equal to 10x + 7, then there would be no solution.

a) Angle of line of sightFrom a point O in the school compound, Adeolu is 100 m away on a bearing N 35° E and Ibrahim is 80 m away on a bearing S 55° E. (a) How far apart are both boys? (b) (c) What is the bearing of Adeolu from point O, in three-figure bearings? What is the bearing of Ibrahim from point O, in three-figure bearings?The angle of the line of sight of Adeolu from the point O is given by:α = 90 - 35α = 55°.The angle of the line of sight of Ibrahim from the point O is given by:β = 90 - 55β = 35°.a) By using the Sine Rule, we can determine the distance between Adeolu and Ibrahim as follows:$

\frac{100}{sin55^{\circ}} = \frac{80}{sin35^{\circ}

100 sin 35° = 80 sin 55°=57.73 mT

herefore, both boys are 57.73 m apart. b) The bearing of Adeolu from the point O can be determined as follows:OAN is a right-angled triangle with α = 55° and OA = 100. Therefore, the sine function is used to determine the side opposite the angle in order to determine AN.

Thus:$$sin55^{\circ} = \frac{AN}{100}$$AN = 80.71 m.

To find the bearing, OAD is used as a reference angle. Since α = 55°, the bearing is 055°.

Therefore, the bearing of Adeolu from the point O is N55°E. c) Similarly, the bearing of Ibrahim from the point O can be determined as follows:OBS is a right-angled triangle with β = 35° and OB = 80. Therefore, the sine function is used to determine the side opposite the angle in order to determine BS.

Thus:$$sin35^{\circ} = \frac{BS}{80}$$BS = 46.40 m.

To find the bearing, OCD is used as a reference angle. Since β = 35°, the bearing is 035°.Therefore, the bearing of Ibrahim from the point O is S35°E. A boy walks 5 km due North and then 4 km due East. (a) Find the bearing of his current posi- tion from the starting point.

(b) How far is the boy now from the start- ing point?The boy's position is 5 km North and 4 km East from his starting position. The Pythagorean Theorem is used to determine the distance between the two points, which are joined to form a right-angled triangle. Thus

:$$c^2 = a^2 + b^2$$

where c is the hypotenuse, and a and b are the other two sides of the triangle. Therefore, the distance between the starting position and the boy's current position is:$$

c^2 = 5^2 + 4^2$$$$c^2 = 25 + 16$$$$c^2 = 41$$$$c = \sqrt{41} = 6.4 km$$

Therefore, the boy is 6.4 km from his starting point. (a) The bearing of the boy's current position from the starting point is given by the tangent function.

Thus:$$\tan{\theta} = \frac{opposite}{adjacent}$$$$\tan{\theta} = \frac{5}{4}$$$$\theta = \tan^{-1}{\left(\frac{5}{4}\right)}$$$$\theta = 51.34^{\circ}$$

Therefore, the bearing of the boy's current position from the starting point is N51°E.

The surface area of a regular pyramid is equal to 1240.4 mm².

In Mathematics and Geometry, the surface area of a pyramid with a regular pentagon as its base can be calculated by using this formula:

Surface area of a pyramid = Area of all the sides + Area of base.

Note: Each side represents a triangle.

For this regular pentagonal pyramid, the area of the five triangles can be determined as follows;

Area of 5 triangles = 5 × 1/2 × base × slant height

Area of 5 triangles = 5 × 1/2 × 16 × 20

Area of 5 triangles = 800 mm²

Surface area of regular pyramid = 800 mm² + 440.4 mm²

The value of dy/dx is -27/8 for 1=5x³+2y²+4xy  at (-1,3).

A differential equation is an equation that contains one or more functions with its derivatives.

Given,

The equation is 1=5x³+2y²+4xy

We need to differentiate the given equation

5.3x²+4ydy/dx+4(xdy/dx+y)=0

15x²+4ydy/dx+4(xdy/dx+y)=0

15x²+4ydy/dx+4xdy/dx+4y=0

15x²+dy/dx(4y+4x)+4y=0

dy/dx(4y+4x)=-15x²-4y

dy/dx=-15x²-4y/4y+4x

Now plug in x =-1 and y=3

dy/dx=-15(-1)²-4(3)/4(3)+4(-1)

=-15-12/12-4

=-27/8

Hence, the value of dy/dx is -27/8 for 1=5x³+2y²+4xy  at (-1,3).

Step-by-step explanation:

I got u dawg

The maximum point that the middle of the rope reaches is 75 inches above the ground.

The correct answer is option (A)

"An amplitude of the cosine function is the amount by which it varies above and below the x -axis."

For given example,

The height of the middle of the rope, in inches, can be modeled by a cosine function with an amplitude of 36 inches.

⇒ h = 2a cos(x)

with a = 36 inches

If the minimum point that the middle of the rope reaches is 3 inches above the ground,

⇒ h = 2a cos(x) + 3

When the middle of the rope reaches the maximum point, then x = 0

⇒ h = 2 × 36 × cos(0) + 3

⇒ h = 72 × 1 + 3

⇒ h = 72 + 3

⇒ h = 75 inches

Therefore, the maximum point that the middle of the rope reaches is 75 inches above the ground.

Step-by-step explanation:

If x < 0 then x is negative.

If y > 0 then y is positive.

If a negative value is multiplied by a positive value, the result is always negative.  For example, (-2) · 3 = -6.  Therefore:

If a negative value is squared (multiplied by itself), the result is always positive.  For example, (-2)² = (-2) · (-2) = 4. Therefore:

If a negative value is divided by a positive value, the result is always negative.  For example, -4 / 2 = -2.

If a negative value is added to a negative value, the result is always negative.  For example, (-2) + (-2) = (-2) - 2 = -4.  Therefore:

If a negative value is subtracted from a positive value, the result is always positive.  For example, 3 - (-4) = 3 + 4 = 7. Therefore:
