Answer:

12 dimes and 36 nickels

Step-by-step explanation:

Let number of dimes be x. Since the number of nickles is three times the number of dimes, the number of nickels is 3x. There are a total of 48 coins, so number of nickels + number of dimes = 3x + x = 4x = 48 -> x =12. So she has 12 dimes and 3(12) = 36 nickels.

Answer:

240

Step-by-step explanation:

So here’s the step by step (for the show your work thingy)

so we can write an equation

0.05x=12

We use 0.05 becuase 5 percent is basically 5/100 and the x is used becuase we don’t know what the number is and the =12 is for the number that came out as a final result

ow we can solve the equation

x=12/0/05

x=240

Final answer is 240

Answer:

x = -1

Step-by-step explanation:

y + 2x = -1

Subtract 2x from both sides;

y = -2x - 1

y = 3x + 4

-2x - 1 = 3x + 4

Subtract 3x from both sides;

-5x - 1 = 4

Add 1 to both sides;

-5x = 5

Divide both sides by -5

x = -1

Answer: A cost function is a mathematical formula used to used to chart how production expenses will change at different output levels. In other words, it estimates the total cost of production given a specific quantity produced.

Answer:

D or y=-2x+4

Step-by-step explanation:

In the graph the y intercept is 2.

In y=-2x+4 they y intercept is 4 so this is not represented by the graph.

Answer:

D. y = -2x + 4

Step-by-step explanation:

When setting up the equation in slope-intercept form (y = mx + b), the 'b' variable represents the 'y' value where the line intercepts the y-axis. The 'm' represents the slope, which is the rate of change. If D was the correct answer, then the line would be placed higher up and would have been tilted down more.

Answer: Isolate the variable by dividing each side by factors that don't contain the variable.

Answer:

False

Step-by-step explanation:

The given statement "A data set can have more than one median" is False.

The mean is the average value which can be calculated by dividing the sum of observations by the number of observations

Mean = Sum of observations/the number of observations

Median; It represents the middle value of the given data when arranged in a particular order.

Mode; It is that number that appears most frequently in the given set of data.

Given the statement as; A data set can have more than one median.

If the value changed is not the middle value (if number of observations are odd) or is not changing the average of two mid values (if number of observations are even), then the median won't change as it does not care about the value of the data unless its about the mid value of the sorted data or average of mid values.

Since the median and mean can only have one value for a given data set. The mode can have more than one value

The given statement is False.

Answer:

3p + 2.25(p - 5) represents the total cost of the pens and pencils that Sandi bought.

Step-by-step explanation:

p = number of packages of pens

p - 5 = number of packages of pencils

3p = cost of p packages of pens

2.25(p - 5) = cost of p - 5 packages of pencils

3p + 2.25(p - 5) represents the total cost of the pens and pencils that Sandi bought.

We are to determine what the expression 3p + 2.25(p - 5) represent.

let

packages of pens = p

packages of pencils = p - 5

cost of p - 5 packages of pencil = $2.25

cost of p packages of pen = $3

Total cost of pencil and pen = (p)3 + (p - 5)2.25

= 3p + 2.25(p - 5)

The expression 3p + 2.25(p - 5) represent total cost of pen and pencils sandi bought

Answer:

The width is 7ft and the length is 17 ft

Step-by-step explanation:

Let w represent the width of the room and L represents the length of the den.

Given that:

caseys den is 10feet longer than it is wide

Then;

w + 10 = L ---- (1)

The area of the den = 119 ft²

Area = w × L

119 = w × L  ---- (2)

From equation (1);

let w = L - 10.

Now we can replace the value of w into equation (2)

i.e.

(L - 10) × L = 119

L² - 10L - 119 = 0

(L + 7) ( L - 17) = 0

L + 7 = 0 or L - 17 = 0

L = - 7 ft  or L = 17 ft

Recall that:

w = L - 10

w = -7 - 10    or    w = 17 - 10

w = -17         or     w = 7 ft

The area of the den can now be:

Area = -17 ft × - 7ft   or       17ft ×  7 ft

Area = 119 ft²           or        119 ft²

Since it is ideal to use the positive integer,

Then the width is 7ft and the length is 17 ft

Answer:

Step-by-step explanation:

1/2+1/3

Using the Pythagorean theorem, the length of the line is: √45 = 6.7 units.

The Pythagorean theorem is the equation that describes how the lengths of the three sides of a right triangle relate to each other. If a and b are smaller legs, and c us the hypotenuse of the triangle, the Pythagorean theorem states that:

c² = a² + b².

Consider the line above to be the hypotenuse of a right triangle that is formed by the rise and run of the line.

Rise = a = 3 units

Run = b = 6 units

Line = c

Therefore:

c² = 3² + 6²

c² = 9 + 36

c² = 45

c = √45

c = 6.7 units.

The fraction form of (5/6)×3 after simplification is  5/2.

A fraction is written in the form of p/q, where q ≠ 0.

Fractions are of two types they are proper fractions in which the numerator is smaller than the denominator and improper fractions where the numerator is greater than the denominator.

Given, (5/6)×3.

= (5/6)×(3/1).

Now in fraction multiplication, we simply multiply the numerator with the numerator and the denominator with the denominator.

Answer:

$247.37

Step-by-step explanation:

The total dinner bill with a tip for the large party is $177.90.

In mathematics, Multiplication operations perform Multiplying values on either side of the operator.

For example 4×2 = 8

The gratuity for a large party is 20% of the bill, so we can calculate the gratuity by multiplying the bill by 0.2.

Gratuity = bill x 0.2

Gratuity = 148.25 x 0.2

Apply the multiplication operation, and we get

Gratuity = 29.65

To find the total bill, we add the gratuity to the original bill.

Total bill = bill + gratuity

Total bill = 148.25 + 29.65

Apply the addition operation, and we get

Total bill = $177.90

Hence, the total dinner bill with a tip for the large party is $177.90.
