What is the value of the function f left parenthesis x right parenthesis equals 20 x when x equals 0.25?

Answer:

5d

Step-by-step explanation:

Mother: 3d

Father: 2d

Total: 3d + 2d = 5d

Without knowing the total number of coins or the ratio between one dollar and two dollar coins in the jar, we cannot accurately determine the number of two dollar coins.

Amadi has a jar with both one dollar and two dollar coins. The question is asking how many of the coins in the jar are two dollar coins.
To determine the number of two dollar coins, we need more information. The question does not provide any details about the total number of coins or the ratio between one dollar and two dollar coins in the jar. Without this information, it is not possible to give an accurate answer.
If we assume that the jar contains a total of 100 coins, we can use algebra to solve for the number of two dollar coins.

Let's say the number of two dollar coins is x. Then, the number of one dollar coins would be 100 - x.
Since the value of the two dollar coins is double the value of the one dollar coins, we can set up the equation 2x + 1(100 - x) = total value of coins.
Simplifying the equation, we get 2x + 100 - x = total value of coins.
Combining like terms, we have x + 100 = total value of coins.
Since we don't know the total value of coins, we cannot solve for x. Therefore, we cannot determine the number of two dollar coins without additional information.

Answer:

x=7

Step-by-step explanation:

x+6+x+x+2=29

3x=21

x=7

Answer:

2x + 3x = $25,000

5x = $25,000

x = $5,000

Amina will receive $10,000, and Mina will receive $15,000.

2:3

First, add 2 and 3 =5

The total money is 5

Then for Amina whose share is 2;

2/5 × 25,000 = GH$10,000.00

For Mina whose share is 3;

3/5 ×25,000 = GH$15,000.00

Therefore

Amina = GH$10,000.00

Mina=GH$15,000.00

Answer:

circle

radius

Step-by-step explanation:

1 ) The diameter measures the circle at its largest point across. Another definition that is related to the diameter is the radius. It is the measurement from the center of the circle to its edge.

2) When a circle's diameter is 1, its circumference is π. When a circle's radius is 1—called a unit circle—its circumference is 2π.    -

Answer:

we need to find the circumference and diameter of circle.

Dimeter of circle = 2× Radius

Diameter of circle = 2 × 6

Diameter of circle = 6cm

Circumference of circle = 2πr

Circumference of circle = 2 × π × 6

Circumference of circle = 12π

Answer:

145.309

Step-by-step explanation:

So we want to find the midpoint of the two number: 145.809 and 144.809, what we want to do it to find the difference between the two numbers and then divide it by 2 so we can find the halfway point:

145.809 - 144.809 = 1

^ So from this, we just have to add half of 1 or 0.5 to the smaller number:

144.809 + 0.5 = 145.309

Answer:

Approximately, there are 8 million insect species.

Step-by-step explanation:

Convert 64% into decimal

64%/100% = 0.64

To get the number of insect species, we just have to multiply the total species of organism by 0.64

Let n be the number of insect species

n = 12,400,000(0.64)

n = 7,936,000

n ≈ 8 million

Answer:

CM = 3

MG = 15

CG = 18

Step-by-step explanation:

CM = x

MG = x + 12

C to G equals 4x + 6

CG = 4x + 6

And CM + MG (CG) also equals  2x + 12

CM + MG = 2x + 12

4x + 6 = 2x + 12 (solve for x)

Subtract 2x from both sides.

2x + 6 = 12

Subtract 6 from both sides.

2x = 6

Divide by 2

x = 3

CM = (3)

MG = 3 + 12 = 15

CG = 4(3) + 6 = 18

Answer:

3

Step-by-step explanation:

Step 1: Define

f(x) = 6ˣ - 4x

g(x) = 1/2x + 10

f(2) is x = 2

g(-2) is x = -2

Step 2: Find f(2) and g(-2)

f(2) = 6² - 4(6)

f(2) = 36 - 24

f(2) = 12

g(-2) = 1/2(-2) + 10

g(-2) = -1 + 10

g(-2) = 9

Step 3: Find f(2) - g(-2)

12 - 9 = 3

The elements of set C that are less than or equal to -11 are -11, -12, -13, -14, and -15.

Set C consists of negative integers greater than -15. In order to determine which elements of set C are less than or equal to -11, we need to identify the negative integers that fall within that range.

Starting with the number -11, we can check if it is included in set C. Since the set C includes negative integers greater than -15, and -11 is greater than -15, we can conclude that -11 is an element of set C.

Therefore, the elements of set C that are less than or equal to -11 are -11, -12, -13, -14, and -15.

Answer: x=7

Step-by-step explanation:

To find the value of x, we can set a proportion since the problem states that "y varies directly with x".

[tex]\frac{13}{65} =\frac{x}{35}[/tex]              

Here, we see that the x is the numerator and y is the denominator.

[tex]\frac{13}{65} =\frac{x}{35}[/tex]              [cross multiply]

[tex]455=65x[/tex]          [divide both sides by 65]

[tex]x=7[/tex]

Now, we know that x=7. Logically, we know this is also correct because y=35 is less than y=65. This tells us that x has to be smaller than x=13.

The value of the variable x for this problem is given as follows:

[tex]x = \frac{5\sqrt{2}}{2}[/tex]

The three trigonometric ratios are the sine, the cosine and the tangent of an angle, and they are obtained according to the formulas presented as follows:

For the angle of 45º, we have that:

Applying the sine ratio, the value of x is given as follows:

sin(45º) = x/5

x = 5sin(45º)

[tex]x = \frac{5\sqrt{2}}{2}[/tex]

Answer:

Step-by-step explanation:

c=2A

An equation is formed when two equal expressions. The correct option is B.

An equation is formed when two equal expressions are equated together with the help of an equal sign '='.

Given that the cost to paint an area of 1,500 square feet is $3,000. Therefore, the equation that gives the relationship between c, cost and A, the area is,

cost = constant × area

c = k × A

$3000 = k × 1500 ft²

k = $2 per square feet

Now, the equation that gives the relationship between c and A can be written by substituting the value of k in the equation,

c = k × A

c = 2 × A

c=2A

Hence, the correct option is B.

Answer:

The answer to this question is given below in the explanation section.

Step-by-step explanation:

The number line helps in understanding the negative and positive numbers.

with the help of a number line, you can easily add and subtract positive and negative numbers.

As it is required to find the sum of -4+2 and -4+(-2) on the number line.

We know that

-4+2=-2

and

-4+(-2)=-6

now we want to know how to represent them on number line.

You know the number line, the center is the origin that is represented by zero, and the number that goes in the right direction are positive numbers and the numbers that go, in left direction are the negative number.

so first we point -4 at the left side of the origin of the number line. then the next number in this equation is +2 which means we have to move from -4 to two-point right on the number line, then we reach point -2 at the number line.

next is -4+(-2)

for this, we point at -4 on the number line, then the next sign is + that means we have to move forward but toward the left direction because of -2. as we left side two points on the number line from point -4 we will reach at -6. so -6 is the answer of this addition (sum).
