What is the fewest number of quarters, nickels, and pennies that can be fairly exchanged for 2 quarters, 6 nickels, and 9 pennies?

Answers

Answer 1

Answer:

Your answer is 3 quarters, 2 nickels, and 4 pennies

Step-by-step explanation:

2 quarters plus 6 nickels plus 9 pennies is equal to 89 cents. So if we subtract 75(3 quarters) we get 14 which is less than 25 therefore we must only use nickels and pennies from now on. If we take 14 and subtract 10(2 nickels) we get 4 which less than 5 leaving us only to use pennies, which one a piece so it must be 4 pennies. Hope this helps!

The first term of an arithmetic sequence is 4. The common difference is 8. What is the 25th term of sequence

Answers

Answer:

196

Step-by-step explanation:

T25=4+(25-1)8

=4+192

T25=196

The 25th term of the arithmetic sequence is 196.

The formula that can be used in finding the nth term of an arithmetic sequence will be: = a + (n - 1)d

where,

a = first term = 4

d = common difference = 8

n = number of terms = 25

Therefore, the 25th term of the sequence will be:

= a + (n - 1)d

= 4 + [(25 - 1) × 8]

= 4 + (24 × 8)

= 4 + 192

= 196

The 25th term is 196.

Answer:

Perimeter = 72

Step-by-step explanation:

Notice that the adjacent (next to) lengths by each corner are equal in length.

This occurs when the quadrilateral is circumscribed.

Since 4.2 is adjacent to the length which makes up the total side 20.

20 – 4.2 = 15.8.

And 15.8 + 4.2 = 20.

(7 + 9) + (9 + 4.2) + (4.2 + 15.8) + (15.8 + 7) =

Suppose that two high school students decide to see if they get the same results as the
researcher. They both do 30 minutes of aerobic exercise and, immediately following the
exercise, take the test. The mean of their scores is = 25.2 seconds, the same as that of the
publication article. It is appropriate to conclude which of the following?​

Answers

Complete question is;

A researcher wishes to determine if aerobic exercise improves mental performance immediately following the exercise. He plans to have high school students participate in 30 minutes of aerobic exercise and then take a standard test of their reasoning skills. Suppose the scores of high school students on this test of reasoning skills immediately after 30 minutes of aerobic exercise follow a Normal distribution with mean μ and standard deviation σ = 4. Suppose also that, in the general population of all high school students, scores on the test of reasoning skills follow a Normal distribution with mean 25 and standard deviation σ = 4. The researcher, therefore, decides to test the following hypotheses.

H0 : μ = 25, Ha : μ > 25

To do so, the researcher has 10,000 high school students do 30 minutes of aerobic exercise and then, immediately following the exercise, take the test. The mean score for these students is = 25.2 and the P-value is less than 0.0001.

It is appropriate to conclude which of the following?

Select one:

A. The researcher has conclusively proved that, for high school students, 30 minutes of aerobic exercise substantially improves mental performance.

B. The researcher has strong evidence that, for high school students, 30 minutes of aerobic exercise substantially improves mental performance.

C. The researcher has moderate evidence that, for high school students, 30 minutes of aerobic exercise substantially improves mental performance.

D. None of the above

Answer:

D. None of the above

Step-by-step explanation:

We see that the researcher wants to test the hypotheses;

Null hypothesis; H0 : μ = 25,

Alternative hypothesis; Ha : μ > 25

Population mean = 25 and standard deviation σ = 4

After testing a sample of 1000 students, he discovered that;

Sample size; n = 1000

Sample mean; x¯ = 25.2

After calculations, he got P-value as less than 0.0001.

Now, he can't make any conclusion or evidence for this research because there is no population mean for the aerobic exercise and also no significance value in the entire question to compare the p-value with.

Thus, none of the options are correct.

Jesse’s age is two times Adam’s age and Adam is three years older than Denise. If the sum of their ages is 33, how old is each person.

Answers

Answer:

Jesse = 18yrs

Adam = 9yrs

Denise = 6yrs

Step-by-step explanation:

Denise = x

Adam = x+3

Jesse = 2(x+3)

x+x+3+2x+6 = 33

4x+9 = 33

4x = 33-9

4x = 24

x = 6yrs

Substitute :

Denise = 6

Adam = 6+3 = 9

Jesse = 2(6+3) = 2(9) = 18

A dairy farmer delivered milk over two days.
On Monday, he used 5 gallons of fuel to drive 40 miles.
• On Tuesday, he drove 120 miles at an average rate of 10 miles per gallon of fuel.
Determine the miles traveled per gallon of fuel on Monday and the number of gallons of fuel used on
Tuesday,

Answers

Answer:

the ans is

Step-by-step explanation:

monday = 40/per gallon

tuesday = 120/per gallon

1) The miles traveled per gallon of fuel on Monday = 4 miles/gallons

2) The number of gallons of fuel used on Tuesday = 12 gallons

What is ratio?

"It is a quotient of two mathematical expressions."

What is average rate?

"The average rate is the total change in output values divided by the change in the input values."

For given situation,

On Monday,

a dairy farmer used 5 gallons of fuel to drive 40 miles.

So, the miles traveled per gallon of fuel would be the ratio of the distance he drove and the fuel used.

the miles traveled per gallon of fuel:

= 20 / 5

= 4 miles/gallon

Therefore, the miles traveled per gallon of fuel on Monday = 4 miles/gallons

On Tuesday,

he drove 120 miles at an average rate of 10 miles per gallon of fuel.

Let he used 'x' gallons of fuel.

⇒ 10 = 120/x

⇒ 10 × (x) = 120

⇒ x = 120/10

⇒ x = 12 gallons

Therefore, he used 12 gallons of fuel on Tuesday.

The graph of a quadratic function with vertex (1,-3) is shown In the figure below . Find the domain and the range

Answers

Answer:

We can not see the graph, but that does not matter.

For a function y = f(x), the domain is the set of the possible values of x that we can input in the function, and the range is the set of the possible outputs.

First, for the domain, we start assuming that the domain is the set of all real numbers.

Then we look at our function, there is a point that causes a problem?

(a problem can be a zero in a denominator, for example)

Well, we have a quadratic equation, then we can not have any "x" in a denominator, then there are not problems, which means that the domain is the set of all real numbers.

For the range we first need to find the minimum (or maximum value) of f(x).

Here we know that the vertex is (1, - 3)

If the arms of the graph open upwards, then the minimum is at the vertex, which means that the minimum value of y is y = -3

And the arms go upwards infinitely, so there is no upper limit.

Then the range is the set of all numbers such that:

-3 ≤ y

Now, if the arms of the graph open downwards, then the maximum is at the vertex, which means that the maximum of our function is at y = -3

And with similar thinking than in the above case, we can find that the range is:

R:  y ≤ -3.

find the number set which satisfies each of these problems:

What is the equation of line?

The equation of the line shown in the graph is determined by calculating the slope and y - intercept of the line as shown below.

The slope of the line is calculated as follows;

m = Δy / Δx

where;

Δy is change in y valuesΔx is the change in x values

m = ( 9 - 3 ) / (2 - 0 )

m = 6 / 2

m = 3

The  y - intercept of the line is the point where the line intersects y-axis.

y = mx + c

Answer:

  a) y = 3x-1

  b) y = x+5

Step-by-step explanation:

a) We notice the x-values change by 1, so the change in the y-value is the slope. -4 -(-7) = 3 is the change between the first two y-values.

The y-intercept is shown by the ordered pair (0, -1). So, the slope-intercept equation is ...

  y = 3x -1

__

b) We note that the change in x is 2 units, as is the change in y. Then the slope of the function is m = 2/2 = 1. The y-intercept (b) can be found from ...

  b = y -mx

  b = 7 -1·2 = 5

Then the slope-intercept equation is ...

  y = x + 5
