Answer:  nickels = 14, dimes = 42, quarters = 18

Step-by-step explanation:

Let n represent nickels which has a value of $0.05

Let d represent dimes which has a value of $0.10

Let q represent quarters which has a value of $0.25

It is given that:

                       n = n

                      d = 3n

                      q = n + 4

and their total value is $9.40    ⇒     n + d + q = $9.40

Use substitution to find the quantity of nickels:

.05(n) + .10(3n) + .25(n + 4) = 9.40

 5n    +  10(3n) +   25(n+4)   = 940           multiplied by 100

 5n    +   30n   +  25n + 100 = 940          distributed

                            60n + 100 = 940          added like terms

                            60n           = 840          subtracted 100

                                 n           = 14            divided by 60

n = 14

                d = 3n

                   = 3(14)

                   = 42

                                       q = n + 4

                                          = (14) + 4

                                           = 18

Answer:

She stopped to rest for 45 minutes.

Step-by-step explanation:

It's where the line is straight. What's the second question?

Answer:

0.75 (45 mins) for both

Step-by-step explanation:

It's because the rest is the time where no activity is happening (the straight line). That line when measured from its start to end is mins 45 to mins 90, and when subtracted, gives 45 mins. For the initial ride it is from where the line moves upward until it stops. That goes from mins 0 to mins 45 ad when subtracted gives 45 mins.

Answer:

The lowest score 4th judge can give this dancer in order for her to move to the semi finals is 7.7.

Step-by-step explanation:

Let x points be the score that 4th judge gave to the dancer.

The first three judges gave the dancer 8.9 points, 7.1 points and 8.3 points.

In total, the dancer got

[tex]8.9+7.1+8.3+x=24.3+x[/tex] points

The average score is

[tex]\dfrac{24.3+x}{4}[/tex]

This average score must be at least of 8 points, so

[tex]\dfrac{24.3+x}{4}\ge 8\\ \\24.3+x\ge 32\\ \\x\ge 32-24.3\\ \\x\ge 7.7[/tex]

The lowest score 4th judge can give this dancer in order for her to move to the semi finals is 7.7.

Answer:

y = x - 4

Step-by-step explanation:

If you look at it, you can see that 8 - 4 is 4

12 - 4 = 8

14 - 4 = 10 and

17 - 4 = 13

The solution is, y = x - 4 , is the function equation for the input/output table.

Function, in mathematics, an expression, rule, or law that defines a relationship between one variable (the independent variable) and another variable.

here, we have,

given that,

x    y

8    4

12   8

14   10

17    13

In order to solve, we replace the values of x in the functions in at least two points, we then compare if the answers correspond with the y-components. From this, we will have that the function that models the table is:

y = x - 4

The table looks like this:

x = 8 => y = 8-4 = 4

x = 12 => y = 12 - 4 = 8

x = 14 => y = 14 - 4 = 10

x = 17 => y = 17 - 4 = 13

Hence, The solution is, y = x - 4 , is the function equation for the input/output table.

Step-by-step explanation:

6 is divisible by 2 and 3 (6 = 2 · 3).

257 is not divisible by 2 and 3 (257 is a prime number).

Therefore 257 is't divisible by 6.

Final answer:

257 is not divisible by 6 because it is not even.

A number must be even and the sum of its digits divisible by 3 to be divisible by 6.

Explanation:

To determine if 257 is divisible by 6, we need to check if it satisfies the criteria for divisibility by 6.

A number is divisible by 6 if it is divisible by both 2 and 3.

Examining 257, we see that it ends with a 7, which is not an even number.

So it does not meet the criterion for divisibility by 2.

Therefore, 257 is not divisible by 6.

The expression is [tex]\frac{n}{2}-6+10[/tex]

For n=8 the value of the expression is 8

Step-by-step explanation:

Let

n -----> the number

we know that

"six less than" means we're subtracting 6:

- 6

"The quotient" means division. "Of a number and 2" Usually the numerator is listed first:

n/2

"increased by ten" means we're adding 10:

+10

substitute

[tex]\frac{n}{2}-6+10[/tex]

For n=8

substitute the value of n in the expression

[tex]\frac{8}{2}-6+10[/tex]

[tex]4-6+10=8[/tex]

Answer:

Expression would be [tex]\frac{n}{2}-6+10[/tex]

Value would be 8.

Step-by-step explanation:

Here, n represents the unknown number,

∵ The quotient of n and 2 = [tex]\frac{n}{2}[/tex]

6 less than  [tex]\frac{n}{2}[/tex] =  [tex]\frac{n}{2}-6[/tex]

[tex]\frac{n}{2}-6[/tex] increased by 10 = [tex]\frac{n}{2}-6+10[/tex]

Thus, the required expression would be,

[tex]\frac{n}{2}-6+10[/tex]

When n = 8,

[tex]\frac{8}{2}-6+10=4-6+10=8[/tex]

Answer:

45mph.

15 x 3 = 45

20 x 3 = 60

so 60 ÷20 = 3

60 divided by 20 is 3

And 15 miles in 20 minutes times 3 is 45 miles in one hour

Answer:

Step-by-step explanation:

To form soil, the two processes which must occur are erosion and weathering, so the correct answer here is B. Soil formation is a continuous process, but also one which takes a long time. It can sometimes more than five hundred years for 1cm of soil to form.

The formation of soil is a complex process that involves various physical, chemical, and biological processes acting over long periods of time.

Some of the key processes involved in soil formation include:

1. Weathering: Weathering is the breakdown of rocks and minerals into smaller particles due to exposure to physical, chemical, and biological agents such as water, wind, temperature fluctuations, plant roots, and microorganisms.

2. Erosion and Transportation: Once rocks and minerals are weathered, the resulting particles are transported by agents such as water, wind, ice, and gravity. Erosion refers to the movement of soil particles from one place to another, while transportation involves the movement of these particles over long distances.

3. Deposition: Deposition occurs when transported soil particles settle out of suspension and accumulate in a new location. Deposition can occur in various environments, such as river deltas, floodplains, glacial moraines, and coastal areas.

4. Organic Matter Accumulation: Organic matter, derived from decaying plant and animal remains, accumulates on the soil surface or mixes with mineral particles. Organic matter plays a crucial role in soil fertility, structure, and nutrient cycling.

Answer:X = 2

Step-by-step explanation:

Apply the distributive property.

2x+2⋅5+4(x−9)=−142x+2⋅5+4(x-9)=-14

Multiply 22 by 55.

2x+10+4(x−9)=−142x+10+4(x-9)=-14

Apply the distributive property.

2x+10+4x+4⋅−9=−142x+10+4x+4⋅-9=-14

Multiply 44 by −9-9.

2x+10+4x−36=−142x+10+4x-36=-14

Simplify by adding terms.

6x−26=−146x-26=-14

Move all terms not containing xx to the right side of the equation.

Add 2626 to both sides of the equation.

6x=−14+266x=-14+26

Add −14-14 and 2626.

6x=126x=12

Divide each term by 66 and simplify.

Divide each term in 6x=126x=12 by 66.

6x6=1266x6=126

Cancel the common factor of 66.

x=126x=126

Divide 1212 by 66.

-16/8 or -16÷8 equals -2 which is a whole number

an integer is a whole number that is positive ,negative or zero

Examples of integers: 1, 2, -5, -18, 20

Not Integers: 0.2, 9.15, 2/3

Final answer:

The division of -16 by 8 results in -2, which is an integer because it has no decimal component. Therefore, -16/8 is an integer.

Explanation:

The question is whether -16/8 is an integer. To determine this, we simply perform the division: -16 divided by 8 equals -2. Since -2 has no decimal component, it is indeed an integer. Integers are whole numbers that can be positive, negative, or zero, but do not include fractions or decimals. Examples of integers include -8, -6, -2, 0, 4, and 12. In this case, -16/8 simplifies precisely to -2, which is an integer.

Answer: I believe first one is 32/99 and the second one is 2 whole numbers and 5/9

Step-by-step explanation:

The number 0.323232... can be written as a fraction 32/99, while the number 2.55555... can be written as the mixed number 2 5/9.

To write 0.323232... as a fraction, you can use the method for converting repeating decimals to fractions. Let's say X = 0.323232... Then 100X = 32.323232..., and subtracting the first equation from the second gives 99X = 32, or X = 32/99.

For the number 2.55555..., we will have our whole number as '2' and we need to convert .55555... into a fraction. Let's use the same method: if Y = .55555..., then 10Y = 5.55555.... Subtracting these gives 9Y = 5, which simplifies to Y = 5/9. So, 2.55555... as a mixed number is 2 5/9.

Answer:

the answer is y = -3x + ( -0.25)

Step-by-step explanation:

The equation of a line with a slope of -3 passing through the point (1.25, -4) can be derived by using the point-slope form (y - y1 = m(x - x1)). Substituting the given values, we get the line's equation as y = -3x - 0.25.

The given problem requires us to write the equation of a line in either point-slope form or slope-intercept form. We are provided with a bit of information to get started: the slope of the line (-3) and a point the line passes through (1.25, -4).

The point-slope form of a line's equation is: y - y1 = m(x - x1), where (x1, y1) are coordinates of a point on the line and m is the slope. Substituting the given values, we get y - (-4) = -3(x - 1.25), which simplifies to y + 4 = -3x + 3.75. Finally, rearranging, we get the slope-intercept form: y = -3x - 0.25.
